NTRODUCTION

The taxation of multinational companies has come under scrutiny by tax administrations,

tax experts and the general public in recent years. More and more evidence suggests that

considerable amounts of corporate income generated in cross-border activities find ways

to avoid taxation. The business models of multinational companies have become more

complex, intra-group transactions have multiplied and multinationals' integrated value

chains make it difficult to determine where profits are created. Governments struggle to

determine within the current set of international tax rules which country should tax a

multinational's income. Smaller businesses are put at a competitive disadvantage and

citizens perceive tax systems as unfair since some corporate taxpayers might be able to

avoid taxation by exploiting tax planning strategies. This perceived lack of fairness

threatens the social contract between governments and their citizens and may impact

overall tax compliance. More generally, the international tax rules suffer from

inefficiencies and are non-transparent. On the other hand, companies still face a very

complex patchwork of 28 national systems with high compliance costs and risks of

double taxation.

The Commission announced in June 2015 to re-launch the proposal for a common

consolidated corporate tax base (CCCTB) to address these issues.

This report presents

the main findings from the impact assessment for this re-launch. The CCCTB was

previously proposed by the European Commission in 2011, based on an impact

assessment concluding that it would greatly improve the business environment in the

single market, making it simpler and cheaper for companies to operate cross-border.

Since 2011, new issues have come into light that reinforce the need for a common

approach to corporate taxation in Europe.

First, aggressive tax planning strategies of multinational corporate groups have become

more prevalent. As outlined above, these tax avoidance activities undermine the very

principle of a deeper and fair single market and generate frustration among honest

taxpayers who in recent years had to make additional efforts to consolidate public

finances after the economic and financial crisis.

Second, the financial crisis has shed light on tax-induced corporate financing structures

that weaken the resilience of businesses and put at risk the financial system and more

generally the economy. Ideally, an efficient corporate tax system should be neutral with

regard to the financing and investment decisions of companies.

Third, European growth and investment remain subdued and businesses in the EU are not

investing enough in R&D activities in comparison to other major economies. European

businesses need to remain competitive and innovative in a globalised world. The

corporate tax system can play an important role in ensuring effective taxation while

minimizing negative impacts on investment and growth.

The introduction of a CCCTB is central to those issues, as it aims to fundamentally

reform corporate taxation and provide a European solution to the current challenges in

the international tax policy arena. It has been recognised that the CCCTB can serve as a

powerful tool in the fight against corporate tax avoidance by removing exploitable

plan for a fair and efficient corporate tax system in the EU (COM/2015/302).

kom (2016) 0685 - Ingen titel

differences and mismatches between national systems. To safeguard the CCCTB against

profit shifting to third countries, it also needs to be equipped with common anti-

avoidance provisions, as spelled out in the June 2015 action plan. A single set of

corporate tax rules will not only remove tax obstacles in the single market, but will make

Europe more attractive to domestic and foreign investment. By making EU tax law

simpler and reducing regulatory costs, it is expected to contribute to a clear, stable and

predictable regulatory framework and improve tax certainty. At the same time, it

provides for the opportunity to address existing financing and investment distortions and

ensure sufficient R&D incentives. The CCCTB would hence contribute to the

Commission's top priority of creating jobs, growth and investment.

Accordingly, the June 2015 action plan identified the CCCTB as a potentially effective

tool to make corporate taxation fairer and more efficient. The action plan announced the

re-launch of the CCCTB, while clarifying that it needed to be strengthened to address the

current challenges in taxation. In that respect, the action plan referred to the fact that the

CCCTB should be made compulsory, at least for multinational corporations, and that

R&D incentives and measures to address current distortions would be considered.

Developing a staged approach to implementing the CCCTB was recommended, focusing

first on the common corporate tax base (common base henceforth) and in a second stage

on the consolidation. The action plan also recalled the detrimental impact on European

competitiveness of the current heavy compliance costs and administrative burdens

created by the patchwork of 28 different national tax bases.

The re-launch of the CCCTB has been included in the 2016 Commission Work

Programme under the priority of creating a deeper and fairer single market.

The work

programme has also announced the withdrawal of the 2011 proposal. The 2016 re-launch

builds on the 2011 proposal and adds the new elements as described above.

The analysis conducted in 2011 showed that the CCCTB has the potential to bring

simplification and reduce costs for companies. It therefore contributes to the

Commission's regulatory fitness and performance programme (REFIT). The CCCTB

initiative has also been identified as one of the important milestones for building a capital

markets union (CMU).

In this context, the Commission committed to address the issue

of the debt-equity bias as part of the re-launch of the CCCTB. The preferential tax

treatment of debt represents an obstacle for creating a stronger equity base in European

companies.

The CCCTB is a major reform proposal to address the current challenges in corporate

income taxation, but experience so far has shown that its negotiation in Council will need

time. To address the most pressing issues in fighting aggressive tax planning the

Commission committed in the June 2015 action plan to other actions aimed at ensuring in

the shorter term effective taxation where profits are generated, a better tax environment

for business, greater tax transparency and strong EU tools for coordination. As a result,

the Anti-Tax Avoidance Package followed in January 2016. It includes legally-binding

anti-avoidance measures necessary to reduce aggressive tax planning. Tax transparency

has been boosted by the Commission's proposals on tax rulings and on country-by-

COM(2015) 215 final.

As described in the action plan on building a capital markets union, COM(2015)468final,

country reporting.

The Anti-Tax Avoidance Package complements existing initiatives

and forums to ensure effective taxation and transparency, such as the Code of Conduct or

the Joint Transfer Pricing Forum. Compared to the more short-term measures, the re-

launched CCCTB offers a holistic solution, which allows tackling important root causes

of the tax avoidance problems.

The CCCTB defines the rules for calculating the taxable profits of a company. The tax

base definition would be the same in all Member States under a CCCTB. However, the

CCCTB does not seek to harmonize the national corporate tax rates. The level of taxation

as determined by the statutory tax corporate rate remains a national decision. The

CCCTB does not change either the domestic corporate tax systems for companies that are

not captured by the scope of the directive or have not opted in. Also, the CCCTB does

not replace bilateral tax treaties and transfer pricing rules which are still needed vis-à-vis

third countries.

This impact assessment and the new CCCTB proposal build on the extensive work done

by the CCCTB working group, the 2011 impact assessment and the technical work done

in collaboration with Member States following the 2011 proposal.

The impact

assessment presented in this document should thus be seen as part of a wider package of

technical studies on the subject

, complementing the existing material with further

evidence, with a focus specifically on the new elements and objectives. Due to the

CCCTB's potential to considerably simplify the corporate income tax system in the EU,

this document was prepared as a regulatory fitness project of the European Commission.

The impact assessment is based on the following logic: The analysis starts with the

withdrawal of the 2011 proposal. The absence of a CCCTB proposal coupled with the

introduction of recent anti-tax avoidance initiatives is the baseline scenario. The impact

of introducing a CCCTB as envisaged in 2011 is assessed and the analysis is further

developed by studying the impact of possible new proposed elements to the CCCTB: a

compulsory requirement for some companies, a solution for the debt bias, a tax incentive

for R&D and a staged approach for its introduction to facilitate the political process.

The analysis concludes that the preferred option would be a CCCTB that is mandatory

for very large multinational companies and optional for others, that includes an

allowance for growth and investment (AGI) with well-designed anti-avoidance measures

and that contains an additional allowance for R&D expenses.

Box 1: The 2011 proposal for a CCCTB

The Commission has highlighted the issues and challenges of corporate tax systems in an Economic

Union as well as their role for competitiveness vis-à-vis third countries for many decades. In 2001, the

Commission presented a communication identifying concrete steps to eliminate tax obstacles to cross-

border trade in the EU. This was followed by 10 years of technical preparation, culminating in the

Commission's 2011 proposal for a CCCTB.

The Commission tabled in March 2011 a proposal for a directive on a CCCTB which lays down

common rules for the calculation of the tax base applicable to companies operating in the EU. This EU

tax framework comprises a full set of corporate tax rules to calculate the individual fiscal results of

companies and permanent establishments which are tax resident, or situated, in the EU. The system

includes rules for consolidating those results (profits and losses) when there are other group members

and to apportion the consolidated tax base to all relevant Member States if it is positive. In other words,

a qualifying company or group of companies would have to comply with only one set of rules for

computing its taxable income, rather than different rules in each Member State where it operates. The

consolidated tax base would be apportioned on the basis of a fixed formula comprising three equally

weighted factors: sales (by destination), labour and assets. Each Member State would apply its own tax

rate to the share of the tax base apportioned through the formula. Only the calculation and

apportionment of the tax base would be harmonised. Member States would retain the power to set their

own tax rates.

The CCCTB was proposed as an optional system. All companies, irrespective of size or whether they

had cross-border operations, would be entitled, but not obliged, to apply the system, provided that they

fulfilled the eligibility requirements of the Directive. The proposal also includes anti-abuse rules and

stipulates how Member States should administer the CCCTB under a 'one-stop-shop' approach.

In 2011, the CCCTB was primarily envisaged as a tool for removing tax obstacles which companies

occasionally suffer when they operate cross-border within the internal market. Companies would thus

benefit from cross-border loss relief, which is an automatic outcome of consolidation (i.e. no more

paying tax on profits in one Member State to the extent that unrelieved losses are being made at the

same time in another Member State). The apportionment of the tax base through a formula would

remove the requirement for lengthy and costly recording and negotiating of intra-group transactions at

notional arm's length prices (i.e. no more transfer pricing within a CCCTB group). Accordingly,

compliance costs would be reduced by providing for a single set of tax rules for calculating the tax

base. Having a common set of rules would also reduce the possibility of double taxation or double non-

taxation and mismatches in general.

Intensive technical discussions followed in Council. After a first reading was completed, the High

Level Working Party (HLWP) agreed in March 2013 that work on the proposal should be structured as

a step-by-step approach and Member States should prioritise the matters related to the tax base.

Accordingly, consolidation would have to be addressed in a second step once the work on the base

would have been sufficiently advanced. At the time, Member States also stated that the proposal was

not yet ready for a political discussion.

After technical work on the elements of the tax base was accomplished, attention shifted towards

highlighting the link between the CCCTB and the OECD initiative against Base Erosion and Profit

Shifting (BEPS). In this framework, discussions focussed on the international aspects of the tax base as

well as certain elements of the CCCTB system, such as controlled foreign company (CFC) legislation

and the interest limitation rule. Both are closely linked to the OECD BEPS work.

At the informal ECOFIN of October 2014, the Council discussed how to make concrete progress on the

CCCTB in the short to medium term. It was concluded that future work should primarily be centred on

the international aspects of the system.

On 28

January 2016 and while work on the re-launched CCCTB proposal was progressing, the

Commission tabled a proposal for a directive against tax avoidance practices. As a matter of fact, the

proposed instrument included most of the elements of the international and BEPS related aspects of the

CCCTB in an effort to lay down a coordinated approach to implementing certain common minimum

standards against tax avoidance in the EU.

HE PROBLEM AND WHY THE

UROPEAN

NION SHOULD ACT

2.1.

Problems with corporate taxation in an international context

Drivers

The taxation of multinational companies has increasingly come under scrutiny in recent

years. The business models of multinational companies have become more complex and

increasing evidence suggests that considerable amounts of corporate income can avoid

taxation.

The root of the problem stems from current international practices for the distribution of

taxable profits in combination with the increase in capital mobility over the last decades.

Capital mobility within the EU has been fostered by the increased economic integration

following key achievements towards a single market and the implementation of a

common currency in the euro area. While this has helped businesses in their cross-border

activities and increased welfare of citizens, the increased capital mobility conflicts with

the lack of coordination of tax policies at the international level. Not only do tax

obstacles still exist in the single market, but tax authorities also struggle to determine

which country should own the rights to tax which share of a multinational's income.

Figure 1: Problem tree

Source: European Commission

The interplay between these factors creates incentives for governments to compete for

highly mobile tax bases, notably accounting profits as well as income related to

intangible assets. In fact, the economic literature shows that governments have reacted to

increased mobility by reducing the statutory corporate tax rates while broadening the tax

bases to lower the risk of profits being shifted outside the country. Governments have

also implemented specific regimes to attract highly mobile tax bases such as royalty and

kom (2016) 0685 - Ingen titel

license payments. This form of tax competition increasingly replaces tax competition

based on headline statutory tax rates and opens up new non-transparent tax planning

opportunities.

Recent evidence points to tax competition being particularly strong within

the EU due to the high economic integration and low trade costs within the EU (Streif,

2015).

The continued strengthening of the single market with respect to goods, capital

and labour in the absence of tax harmonisation has intensified this effect (Redoano,

2014).

While incentives for tax competition have increased, there is at the same time a tendency

to protect domestic tax bases through anti-avoidance rules. Introducing anti-abuse

measures by Member States is a valuable short-term solution to fix the most pressing

issues. However, the uncoordinated implementation of such measures can create new

barriers to cross-border investments and thereby hamper the overarching goals of the

single market, the creation of a capital markets union and the overall attractiveness of the

EU at the global level. Moreover, they render the international corporate income tax

(CIT) system ever more complex, which in itself may exacerbate the tax avoidance

problem. More generally, uncoordinated national actions contribute to creating new tax

mismatches and loopholes that can be exploited by multinational firms.

Problems

Improvements in the tax area to the functioning of the single market have brought some

key advantages to multinational companies active in several EU countries. Notably, they

benefit from withholding tax exemptions on intra-group interest, royalty and dividend

payments and from tax-neutral cross-border reorganisations

, as well as a fairly narrow

application of controlled foreign company (CFC) rules between most EU Member

States.

In short, they are treated as if they were operating only domestically. At the

same time, their multinational group structure allows them to exploit mismatches in the

interaction of national tax systems, locate intellectual property where they achieve the

most attractive tax savings and treaty-shop in the EU for the most attractive withholding

tax regimes vis-à-vis a specific third country.

The existence of tax avoidance in the form of profit shifting and base eroding practices is

demonstrated in many academic studies. Although the extent of these practices and their

impact on total tax revenues is hard to measure, the existing evidence suggests it is

considerable. The OECD/G20 BEPS report on Action 11 for example estimates the

revenue loss at the global level at 4-10% of CIT revenue, i.e. USD 100-240 billion

Evidence for tax competition and the evolution of tax rates and bases in the EU have been summarised

in the Staff Working Document accompanying the June 2015 action plan (European Commission,

2015b).

Low trade costs have two effects: (1) they tend to concentrate foreign direct investment from third

countries in one Member State, from where other Member States are reached via exports instead of

investing more evenly in the EU; (2) with decreasing trade costs, foreign direct investment within the

EU might become relatively less attractive compared to intra-EU exports.

According to the rules laid down in the Merger Directive, the Parent-Subsidiary Directive and the

Interest and Royalty Directive.

Following the European Court of Justice Decision, the fundamental freedoms imply that CFC rules in

the EU only apply to wholly artificial arrangements. The situation is slightly different in Denmark

(where CFC rules also apply to domestic cases), Lithuania (which applies a white list for EU countries,

but subject to conditions) and the UK (which has not implemented a specific clause for the EU) (see

page 58 of ZEW (2016c) for a discussion).

kom (2016) 0685 - Ingen titel

annually at 2014 levels. In a study covering 51 countries, the IMF concludes that "the

(unweighted) average revenue loss is about 5 per cent of current CIT revenue – but

almost 13 per cent in non-OECD countries". Additionally, a recent study commissioned

by the European Parliamentary Research Service finds that the revenue loss from profit

shifting amounts to about EUR 50-70 billion in the EU, equivalent to 17-23% of CIT

revenue in 2013.

Other studies have not attempted to measure the total revenue loss, but are nonetheless

indicative of the potential size of the problem. Lee et al. (2015) find that 22% of

companies in their sample have a 'large tax gap', meaning that their tax payments

correspond to at most 90% of the taxes they would theoretically owe according to where

they generate their revenues. Furthermore, there is evidence of the sensitivity of affiliates'

profits to CIT rates: reported profits are higher in low-tax jurisdictions than in high-tax

jurisdictions.

Synthesizing 25 studies, Heckemeyer and Overesch (2013) find that an

increase in the CIT rate by 1 percentage point leads to a lowering of affiliates' pre-tax

profits by 0.8% on average.

An important cross-border tax obstacle for companies active in several Member States is

having to deal with up to 28 different rulebooks and up to 28 different tax

administrations. They also have to deal with international rules set by bilateral tax

treaties between Member States. In addition, they are faced with an extremely complex

system for determining how intra-group transactions should be taxed (transfer pricing),

and often cannot offset their losses in one Member State against profits in another.

The

result is that most businesses are faced with high costs and complexities, while smaller

businesses are often completely deterred from expanding within the EU. This could be

particularly detrimental for young companies that foster innovation dynamics and are an

engine of job creation. Cross-border obstacles hindering the functioning of the single

market motivated the 2011 proposal for a CCCTB

and most of the 2011 findings on

these obstacles are still valid today. A majority of companies find the current regimes

difficult to operate, particularly transfer pricing requirements and dealing with audits in

various Member States.

The latest available statistics under the EU arbitration

convention show that the number of pending disputes has further increased since 2008

and the number of requests to resolve disputes has also gone up in recent years.

Moreover, the growing number of anti-avoidance regulations adds to the complexity of

the international corporate tax system, potentially creating additional double taxation

cases and leading to higher administrative costs for both businesses and administrations.

Consequences

The negative consequences resulting from corporate tax avoidance, the complex

international tax system and other tax obstacles are manifold, but they particularly raise

See Sullivan (2004) and Clausing (2011).

Denmark is one exemption, where corporations can opt for international joint taxation for the group.

Corporate taxation has been recognised much earlier as a fundamental component of the single market.

See e.g. the 2000 report by the CEPS Tax Task Force, Radaelli (2000) and the discussion in annex X.

These findings are based on a 2013 review of methods to compute compliance costs (Ramboll

Management Consulting, The Evaluation Partnership and Europe Economic Research, 2013).

The EU arbitration convention establishes a procedure to resolve disputes where double taxation

occurs between enterprises of different Member States as a result of an upward adjustment of taxable

profits by one Member State.

kom (2016) 0685 - Ingen titel

issues of fairness among taxpayers and may constitute barriers to cross-border

investment. Tax avoidance leads to a poor congruence between the jurisdiction where the

value is created and the one where corporate profits are taxed. This contributes to an

unfair distribution of the tax burden, alongside a tendency of national governments to

respond by tapping less mobile tax bases, an additional benefit for multinational

businesses. In the light of fiscal adjustment needs following the economic and financial

crisis (public debt levels have increased in the EU from around 58% of GDP in 2007 to

an estimated 86% of GDP in 2017), many governments have cut expenditures and

increased taxes, notably on consumption, to consolidate public budgets. This has raised a

question about multinationals and their fair contribution to government budgets.

There is clear evidence for an uneven playing field between multinational entities and

domestic firms. A recent study by the ZEW (2016c) has shown that the use of cross-

border tax planning in the EU can considerably reduce effective taxation levels (Table

1).

Tax planning reduces both the mean effective average tax rate (EATR) in the EU as

well as the minimum and maximum EATRs

. The average reduction is substantial.

Lower effective taxation levels for multinational entities have also been evidenced

empirically. For instance, Egger et al. (2010) compare the tax liabilities of multinationals

with those of domestic firms and find that foreign-owned affiliates in high-tax European

countries pay 32% less tax than domestically owned companies. A similar study by Finke

(2013) for Germany finds a gap of 27%.

Notes: Hybrid financing: A parent located in the EU or the US finances an intermediate company located in an 'EU

average' country which grants a 'hybrid loan' to a subsidiary located in the EU. The hybrid loan is treated as

equity in the EU average country and as a loan in the subsidiary country.

Intellectual property box: A parent located in the EU finances both, an intermediate company in an EU

country that has an attractive intellectual property box regime and another subsidiary in the EU or the US.

The intermediate company licenses the intellectual property to the subsidiary and receives royalties from the

subsidiary. The figures show the extreme case where the intellectual property is the only productive asset of

the multinational.

Financing via offshore treaty: A parent located in the EU or the US finances an intermediate company located

in a zero-tax country which has concluded tax treaties with EU countries. The intermediate company grants a

loan to a subsidiary located in the EU and receives interest payments from the subsidiary.

Mean: In the domestic case the mean is the simple EU-28 average, while in cross-border cases, the mean is

the average over all possible combinations of parent-subsidiary locations in the EU-28 and the US.

The possibilities for hybrid loan financing by corporate groups and the ensuing double-non taxation

have been reduced due to the 2014 amendment of the Parent-Subsidiary Directive, effective as of

2016.

Effective average tax rates are driven by the respective statutory CIT rate in each country, which partly

explains the wide spread.

kom (2016) 0685 - Ingen titel

Aside from the harmful perception of the tax system being unfair, including its negative

impact on taxpayer morale (see discussion in Section 5.1), the resulting competitive

distortions weigh negatively on the economy. Tax avoidance and aggressive tax planning

by multinational companies distort price signals in the single market and thereby the

allocation of resources. A recent study by the OECD estimates that mark-ups of

multinational entities are on average 10% higher than those of domestic groups with

similar characteristics while the mark-up of a tax-planning MNE is up to 23% higher. For

multinational groups with links to zero-tax countries or operating in a large number of

countries the mark-ups are estimated to be even higher. Multinational enterprises are also

found to operate in more concentrated industries.

Companies which use tax avoidance

are more profitable and face lower capital costs compared to domestic companies. Higher

mark-ups weigh on growth and are detrimental to equality.

In addition, important

economic resources are wasted on unproductive tax planning activities.

On the other hand, the negative consequences highlighted in the 2011 impact assessment

remain: high tax compliance costs and double taxation risks coupled with few

possibilities for cross-border loss offset constitute an important barrier to cross-border

investment and impede the EU's attractiveness as an investment destination.

The main findings on tax compliance costs for firms from the 2011 impact assessment

were that they are high and significant, mostly due to frequent changes and complexity of

tax laws, and that they are regressive: The estimate for large companies is about 2% of

taxes paid, while for small and medium sized enterprises (SMEs) the figure is about 30%

of taxes paid. These findings are confirmed in a survey of empirical estimates by

Eichfelder and Vaillancourt (2014) for the period between 1984 and 2014. Research also

shows that those compliance costs do not appear to be diminishing over time.

Evidence on cross-border tax compliance costs remains scarce, even though they are

arguably higher than in the domestic case since the rules of two countries have two be

applied in addition to international tax rules which have to be considered (double tax

treaties). In line with this, the 2011 impact assessment finds that compliance costs

increase with cross-border activity and with increasing number of subsidiaries. Early

contributions such as the 1992 Ruding report provide a first survey of cross-border

compliance costs for EU companies, which were found to be at around 3% of total

income of the surveyed companies.

A more detailed overview of the main findings on

tax compliance costs is provided in annex VII.

neutral and investment friendly tax system. This would contribute to a successful capital

markets union, attract inward investment to the EU, and result in a more resilient

corporate sector by removing financing distortions.

Taxation is indeed a key component

of the business environment. It influences companies' investment and innovation

decisions through its impact on the cost of capital. Two issues stand out in particular: the

debt bias and the tax treatment of R&D expenditures.

2.2.1. Debt bias

Drivers and problems

Most corporate tax systems favour debt over equity because interest expenses for debt are

largely tax deductible in contrast to equity costs. The result is a difference in effective

taxation between investments financed by debt and those financed by equity. The debt

bias has been recognized by the European Commission and other relevant international

organisations as a major problem.

Figure 2: Cost of capital - difference between new equity and debt financing

Source: ZEW (2015, 2016a)

Note: The graph shows the cost of capital at the level of the company for new equity and debt as well as the

difference between them for each Member State in 2015. The indicator takes into account the ACE provisions

in Belgium and Italy. The assumption is that the notional interest rate granted is equal to the market interest

rate in the model. This results in full financing neutrality.

Because of this different tax treatment, an equity financed investment needs to earn a pre-

tax return that is higher than the one required by a debt financed investment. In a

concrete example this means that if the investing company has an alternative safe

investment that earns 5%, the investment financed by debt would need a pre-tax return of

This is in line with the tax recommendations in the European Semester.

See for example the various

Annual Growth Surveys

published by the European Commission in the

context of the European Semester, the action plan on building a capital markets union, the publications

of the International Monetary Fund (IMF, 2009, 2010; de Mooij, 2011a) or the Organisation for

Economic Cooperation and Development (OECD, 2015a), and the Financial Stability Board (2015).

kom (2016) 0685 - Ingen titel

only 4%, while equity needs to earn 6.1%.

Figure 2 presents this 'required return' - also

called cost of capital - for Member States in 2015. It shows that the bias is present in

nearly all countries, as the cost of capital for investment financed by new equity is larger

than the cost of capital for investment financed by debt.

Consequences

There is ample empirical evidence that the corporate debt bias significantly affects

financing decisions of companies, both in the financial and the non-financial corporate

sector. In the non-financial sector, de Mooij (2011b) finds that a 10 percentage point

higher corporate tax rate increases the debt-asset ratio by between 1.7 and 2.8 percentage

points.

The result is an increased indebtedness of non-financial companies due to the

debt bias.

The debt bias encourages non-financial corporations to use more debt than equity. The

higher leverage makes companies more fragile and less resilient and may result in an

increased volatility of the business cycle and disproportionate levels of bankruptcy costs.

Indeed, Sørensen (2015) estimates that the debt bias leads to a debt-asset ratio which is

about 2-3 percentage points above the socially optimal level

. This is partly attributed to

the fact that firms do not account for the welfare costs of financial distress when

choosing their debt levels.

The debt bias also has a negative impact on growth. According to research conducted at

the Bank for International Settlements, debt levels exceeding 90% of GDP for the non-

financial corporate sector become deleterious for growth.

This negative effect of debt

on growth is also identified by the European Central Bank (2014, p. 112). In 2014 the

non-consolidated non-financial corporate debt level in percent of GDP was above that

level in 18 of the 28 Member States and was above 150% in six of them.

The debt bias misallocates capital and may hamper the growth of stock market

capitalization, the latter being associated with higher GDP per capita. In addition, the

debt bias is particularly detrimental for young and innovative firms, whose access to

external funding is more difficult. Thus it puts at a disadvantage exactly those firms that

are important for economic growth (including by slowing down the exit of highly-

indebted low-productivity firms). As a consequence the welfare costs associated with the

Annex X explains the underlying model.

This result could be a lower bound: recent studies that rely on tax return data rather than commercial

balance sheets find that the estimated tax effect on capital structure using financial statements is likely

to be biased downward. Devereux et al. (2015) show that the external leverage of domestic stand-alone

companies and of multinational companies responds strongly to corporate tax incentives.

Taxation is not the only driver of indebtedness but econometric techniques allow disentangling the

respective effects of the various drivers and point to a large role for taxation.

The socially optimal level is defined as the one that maximises total rent to society generated by an

investment. See also equation 3.1 in Sørensen (2015).

See Cecchetti et al. (2011).

non-financial corporations are Debt securities (F.3) and Loans (F.4). Data are presented in non-

consolidated terms, i.e. including transactions within the same sector.

kom (2016) 0685 - Ingen titel

lack of deductibility of the cost of equity for young and innovative firms may be

particularly relevant. Overall, the welfare impact is not negligible.

Recent research has also shown that despite stricter capital requirements for banks, the

debt bias also plays a significant role in the financing structure of financial institutions, in

clear opposition with the aims of regulations strengthening the equity base. For banks

with an amount of equity larger than the minimum regulatory requirement, the

responsiveness of the debt-asset ratio to corporate tax rate increases is similar to the one

for the non-financial sector.

Moreover, the adverse impacts in the non-financial and

financial sectors reinforce each other to the extent that the sectors provide funds to each

other. By discouraging firms from building a strong equity base and tapping capital

markets, the debt bias has contributed to excessive leverage also in the financial sector

and potentially magnified the negative effects of the financial crisis: Langedijk et al.

(2014) and de Mooij et al. (2014) find that eliminating the debt bias could decrease both

the likelihood of financial crises and their costs for public finances. The potential gains

from the reduced probability and cost of crises are estimated by both studies to be

between 0.5 and 11-12% of GDP (reflecting the low and high range of tax elasticities).

Finally, the preferential tax treatment of debt generates opportunities for aggressive tax

planning. At a cross-border level, the deductibility of interest expenses creates

opportunities to decrease reported profit via debt-shifting – for example by using hybrid

instruments (considered as equity in one country, but as debt in another).

Figure 3

summarises the different drivers and consequences of the debt bias.

See Fatica et al. (2013, p. 11) for a discussion.

Empirical evidence for the debt bias in the financial sector is among others provided by Gropp and

Heider (2010), Hemmelgarn and Teichmann (2014) and Keen and de Mooij (2012).

Huizinga et al. (2008) provide empirical evidence for this type of profit shifting.

2.2.2. The tax treatment of R&D expenditures

Drivers

R&D investment is a key driver of productivity and economic growth. However, private

companies do not sufficiently invest in R&D from a welfare perspective. The reason is

that companies do not take into account the positive externality from knowledge

spillovers which benefit the whole economy. Indeed, the social returns from R&D

investment are estimated to be two to three times higher than the private returns of firms

on the investment.

In addition, the risk and the uncertainty of returns are much higher

for R&D investments and their returns are highly skewed, which again leads to lower

investment.

The IMF (2016) shows that fully internalizing the externalities of R&D

would lead to 40% higher investments compared to the status quo. Such an increase

could lift GDP in individual economies by 5% in the long term - and globally by as much

as 8% due to international spillovers.

Problems and Consequences

The underinvestment in business R&D is particularly pronounced in the EU. While the

world is becoming more R&D-intensive, the relative weight of the EU is decreasing,

mainly due to the rapid rise of China. The EU is moreover not on track to reach its target

of investing 3% of GDP in (total private and public) R&D by 2020. The underinvestment

in business R&D is one of the reasons behind the widening of the EU's productivity gap

compared to the US. The shortfall mainly reflects a deficit in business R&D expenditure.

Business in the EU spend far less on R&D than businesses, e.g. in the US and Japan, and

the latest figures show a further increase of the gap (Figure 4). To reach the 3% R&D

target, large additional R&D investments are needed. Assuming that two thirds of the

investment should come from the private sector, the business R&D investment gap was

EUR 98 billion in 2014.

R&D tax incentives are an important policy tool, which is now used by the majority of

EU countries (and beyond). In response to the challenging economic environment, almost

all Member States widened their R&D tax incentives and five other countries have

introduced new measures.

The OECD (2016) estimates that R&D tax support

accounted for at least 43% of fiscal support for business R&D in 2013. However, not all

measures are effective.

The diversity of schemes could result in an increasingly

complex landscape for R&D tax treatment in Europe hindering trans-European

collaboration. In its 2006 Communication on the more effective use of tax incentives in

favour of R&D, the Commission already encouraged Member States to improve the use

and coordination of R&D tax incentives. Figure 6 summarises the different elements

discussed above in a problem tree which relates drivers, problems and consequences.

See Garnier et al. (2014) for an overview of tax reforms in the EU.

Governments can draw on several experiences with the design of R&D tax incentives given that such

schemes have been deployed in most advanced economies over the last decade or longer. These

experiences are evaluated in a study by CPB (2014) carried out for the European Commission in 2014

which also benefited from exchanges with Member States representatives and concluded with a list of

good practices in terms of the design of R&D tax incentives.

How the problems affect stakeholders

Multinational enterprises are negatively affected by the problems outlined above to the

extent that they have to deal with numerous national tax systems which creates high

compliance costs and uncertainty. On the other hand, some companies do benefit from

the tax planning opportunities generated by the current international tax architecture.

SMEs face high costs of investing and growing abroad due to differences across national

tax systems. There is no level-playing-field since SMEs cannot reduce their tax burdens

by tax planning measures which leads to distortions in the internal market and raises

fairness issues.

The current tax systems provide incentives for Member States to possibly engage in

harmful tax competition to attract highly mobile tax bases. As a consequence of such tax

competition, some Member States will lose tax bases, while others gain from adopting

tax provisions that are advantageous for attracting mobile tax bases.

Citizens perceive the fairness of tax systems being hampered by the fact that some

taxpayers have means to reduce their tax burden significantly by playing with the rules.

This perception can reduce overall tax morale and more broadly damage the social

contract between citizens and governments.

2.4.

Baseline scenario based on recent developments

The baseline scenario assumes that the CCCTB as tabled in 2011 is withdrawn. It reflects

the latest initiatives to clamp down on corporate tax avoidance and ensure fair and

efficient taxation in the EU. The June 2015 action plan acknowledged that the CCCTB is

a very ambitious proposal that would require time to be completed. It identified several

kom (2016) 0685 - Ingen titel

actions aimed in the shorter term at enhancing effective taxation where profits are

generated, creating a better tax environment for business, enhancing tax transparency and

strengthening EU tools for coordination.

Following the crisis and the increased revenue needs, the OECD proposed an action plan

on base erosion and profit shifting (BEPS) to reinforce the current international tax rules

and stabilise national tax bases. The BEPS project focuses on the interaction of different

(national) tax rules and tries to detect and close loopholes in the current tax architecture.

The action plan laid the basis for developing an EU approach

to implementing some

international aspects of the common base that are linked to the OECD/G20 BEPS project.

As a result, the Commission proposed in January 2016 the Anti-Tax Avoidance Package,

made up of four proposals to ensure that tax is paid where the value is generated and that

tax information is effectively accessed. The elements of the package are detailed in annex

VIII. Its central element is the

Anti-Tax Avoidance Directive

which was politically

agreed by the Council on 21st June 2016 and legally adopted on 12th July 2016. It puts

forward tax rules aimed at preventing that income goes untaxed (or taxed at very low

level),

inter alia

an interest limitation rule, controlled foreign company rules, and rules

on hybrid mismatches.

The other elements of the package consist of: (i) an

Amendment to the existing Directive

on administrative cooperation

to implement automatic exchange of information on

country-by-country reports of multinational companies with consolidated revenues of at

least EUR 750 million; (ii) a

Recommendation on Tax Treaty issues;

(iii) a

Communication on External Strategy for Effective Taxation

setting out a coordinated EU

approach against external risks of tax avoidance and to promote international tax good

governance.

The Anti-Tax Avoidance Package complements existing initiatives and forums to ensure

an effective taxation, enhance tax transparency and address the risk of double taxation.

The proposal for an automatic exchange of information on tax rulings was adopted by the

Council in December 2015. A proposal to introduce public reporting requirements for

multinational entities with turnover above EUR 750 million was adopted by the

Commission in April 2016. In line with the action plan of June 2015, the Commission is

currently exploring various options for a coordinated EU approach to improve dispute

resolution mechanisms, following a public consultation. The Commission is also willing

to respond to the invitation for tabling a proposal on hybrid mismatches involving third

countries, as this arises from the statement which accompanied the political agreement on

the Anti-Tax Avoidance Directive.

Thus the baseline scenario, against which all policy options will be evaluated, is one in

which there is no CCCTB, but the Anti-Tax Avoidance Package and public country-by-

country reporting are implemented.

This would allow for a coordinated implementation of the new international standards agreed in the

package. The Treaties require that the fundamental rights – including the freedom of establishment –

be respected. Reforms must therefore be tailored for the EU content and fix inconsistencies on an EU-

wide basis.

Subsidiarity

Subsidiarity and proportionality, EU added value

Although the problems and market distortions explained in the previous subsections have

distinct origins, it seems that their harmful effects can be tackled effectively only through

a common solution: that is, the approximation of corporate tax regimes in the EU would

mitigate distortions in the market by creating a fairer and more coherent tax environment

for businesses. For this objective to come into fruition, action is necessary to be taken not

separately by Member States in an uncoordinated fashion, but at the level of the Union

instead. Initiatives, planned and implemented by each Member State individually, would

only perpetuate, or even exacerbate, the current situation, as taxpayers would still need to

deal with 28 diverse and sometimes, conflicting tax systems.

The envisaged re-launch of the CCCTB aims to respond to the need for increased growth

and job creation in the post-crisis EU, as well as countering aggressive tax planning

practices. All these objectives essentially seek to tackle problems beyond a single

Member State which by nature require a common approach. In this light, any measures

could only bring results if the rules were applied in a uniform fashion across the single

market. If not, the landscape in the field of corporate taxation would remain fragmented

and the current situation would persist, allowing fiscal obstacles and unfair tax

competition practices to continue to flourish.

What is more, tax avoidance practices are nowadays primarily set up in a cross-border

context. It is indeed the interaction between different tax systems that generates

opportunities for abuse or facilitates taking advantage of mismatches in the interaction of

national corporate tax rules. In addition, the fact that the EU is an internal market with a

high degree of integration presumes enhanced cross-border activity, which underscores

the significance of agreeing to coordinated solutions.

More specifically, most key features of the CCCTB system, such as relief for cross-

border losses, tax-free internal group restructurings, the elimination of complex intra-

group transfer pricing as well as the apportionment of revenues by a formula at the level

of a group have a cross-border underpinning and could only be addressed within a

context of common regulation.

Thus, the EU added value follows from the fact that a

certain degree of uniformity is necessary for the purpose of effectively tackling identified

distortions in the market caused by mismatches, double taxation or non-taxation.

Common rules are also a prerequisite for creating a 'one-stop-shop' for companies or

groups of companies operating across the EU.

Considering the scale and effects of the envisaged CCCTB, its objectives would be better

achieved at Union level, to attenuate the distortions resulting from the current interaction

of 28 national tax regimes and create more favourable conditions for cross-border

investment in the single market.

Proportionality

The envisaged measures are both suitable and necessary for achieving the desired end.

They do not go further than harmonising the corporate tax base, which is a prerequisite

For an overview of the elements of the CCCTB mentioned here see also annex X.

kom (2016) 0685 - Ingen titel

for curbing identified obstacles that distort the single market. Furthermore, the explored

initiatives do not restrict Member States' capability to determine the composition and

desired amount of tax revenues that they collect in order to meet their budgetary policy

targets. In this regard, they do not affect Member States' sovereignty over setting their

own corporate tax rates.

Although the Commission has consistently promoted the coordination of national tax

practices, coordination alone is not sufficient for eradicating tax-related distortions in the

single market. Experience has shown that coordination is a slow process and the results

of such exercises have hitherto been modest. Moreover, tax coordination typically

addresses only specific, targeted issues and cannot cater for the wide variety of problems

faced by companies in the single market.

The rules would contribute to improving the functioning of the single market through a

more efficient way for collectively managing problems that emerge from the interaction

of disparate national corporate tax systems.

EU added value

The taxation of multinational companies in a framework of national corporate tax

systems and bilateral tax treaties faces considerable challenges. While the integration of

markets has made progress and generates benefits for companies as well as for citizens,

the taxation of income from corporate activities across the EU remains a national task.

This can lead to frictions in the single market due to tax obstacles.

In this context, the value-added of EU action is to maintain and further improve capital

mobility within the Union by decreasing compliance costs and tax obstacles. At the same

time, EU action ensures that the activities of multinational companies within the EU do

not avoid a fair level of taxation. An integrated EU approach to the taxation of corporate

income allows Member States to tax the income generated within their boundaries with

the corporate tax rate they consider appropriate. A common approach to an EU tax base

therefore helps to re-establish the link between taxation and value creation. Acting at EU

level would not only replace the current mechanism of taxing corporate profits with a

system based on attributing income where the real economic activity takes place, it

would also eliminate the costly transfer pricing procedures since the tax base would be

consolidated at EU level.

BJECTIVES

The June action plan announced the CCCTB as a proposal to strengthen the single

market by ensuring a fair, efficient and growth-friendly corporate tax system which is

immune to aggressive tax planning practices and based on the principle that companies

should pay taxes in the country where profits are generated. Work on this impact

assessment has led to the identification of the following general and specific objectives,

which are consistent with those of the action plan.

kom (2016) 0685 - Ingen titel

3.1.

General objective: Enhancing the fairness of the tax system

A first important aim is to enhance the fairness of the tax system by addressing some of

the root causes of corporate tax avoidance by multinational companies. The specific

objectives supporting this general goal are to



(i) significantly reduce cross-border tax planning possibilities;



(ii) create a more level playing field between domestic and multinational companies;



(iii) ensure that companies pay a fair share of the tax burden; and



(iv) enhance general tax payer morale, which is currently seriously undermined by a

strong perception that international players are largely escaping taxation.

3.2.

General objective: Stimulating growth and investment

The improvement of the business environment by removing single market tax obstacles

was the central objective of the 2011 CCCTB proposal. This objective remains important

in order to maintain or even enhance the competitiveness of companies in the EU and is

reflected in the 10 Commission priorities which put an emphasis on strengthening jobs,

growth and investment as well as the single market.

The specific objectives to support

this goal are to



(i) significantly simplify within the EU the currently highly complex international

system of corporate taxation to reduce compliance costs and administrative burden;

and



(ii) eliminate double taxation risks within the EU and remove still existing

discriminations and restrictions.

Supported by lessons learned following the financial crisis and given the still modest and

uneven economic recovery, two more objectives have been identified that a reform of the

corporate tax system for the EU should deliver:



(iii) provide an approach to profit taxation that does not distort investment and

financing decisions; and



(iv) create more incentives to invest in the EU,

inter alia

by supporting R&D and

innovation to safeguard and enhance current welfare levels.

In light of the current

underinvestment in business R&D (compared to its importance for innovation,

productivity and economic growth), a minimum requirement should be that the

preferred option maintains the current tax incentives for R&D expenses. Incentives

going beyond the current levels in the EU need to be balanced against the revenue

costs for providing such incentives.

The 10 priorities are summarized here:

https://ec.europa.eu/priorities/index_en.

This is in coherence with the Commission's objective to stimulate more investment and jobs in Europe

under the Investment Plan.

kom (2016) 0685 - Ingen titel

One should note that there is a trade-off between the general objectives. Notably,

reducing costs for companies and fostering investment by more attractive allowances and

deductions could in some cases be difficult to reconcile with ensuring effective taxation

by reducing tax planning opportunities. In addition, it can also impact tax collection.

Therefore the two general objectives need to be balanced. The objective to stimulate

growth and investment needs to be put in coherence with the objective of enhancing the

fairness of the tax system and should not result in more tax planning opportunities.

Notably, experiences with some of the measures taken at national level to tackle the debt

bias and to promote R&D point to the need for a specific anti-abuse design. Provided that

due attention is given to the design and anti-abuse framework, reforms in these areas

would actually provide for an opportunity to tackle specific tax avoidance channels. For

example, addressing the debt bias could remove opportunities for groups operating cross-

border to shift profit via the debt instrument.

OLICY OPTIONS

In line with the action plan of June 2015 and the existing CCCTB proposal, the main

option for a policy proposal will centre on the CCCTB as proposed and discussed in the

Council since 2011 (see Box 1). This is in the following referred to as the 'central

scenario'. The impact of having an interim stage without consolidation and

apportionment, but with the possibility of some form of cross-border loss relief has also

been examined (Sections 4.5 and 5.5). A key element within the options for a CCCTB is

its scope (Sections 4.2 and 5.2), determining which taxpayers should be subject to

mandatory application of the CCCTB and which taxpayers could be allowed to opt into

the system. Further, there are naturally many different options to choose from for the

design of the CCCTB. Most of the relevant design elements have been evaluated

thoroughly in the preparations for the 2011 proposal. Discussions have subsequently

progressed in Council. The present impact assessment therefore focusses on assessing

options for new elements that were not yet discussed in the earlier proposal: measures to

tackle the debt bias (Sections 4.3 and 5.3) and R&D tax incentives (Sections 4.4 and 5.4).

Table 2 gives an overview of the intervention logic by linking problems, objectives and

policy options as well as providing the context for the initiative.

The analysis focuses on the new elements that are added to the original proposal, but all

comparisons are always made against the 'no CCCTB' baseline scenario. Note also that

the additional options (debt bias solution, R&D incentives, etc.) are analysed here as

separate policy interventions, whereas they are in reality provisions of the corporate tax

base included in the CCCTB proposal and not separate proposals on their own.

4.1.

Option 1: No further EU action

In case of no further EU action, the expected evolution of the current situation is as

described in the baseline scenario. Notably, the CCCTB would not be implemented, but

the Anti-Tax Avoidance Package is implemented and eventually public country-by-

country reporting by large multinational entities will be in place. The root problems

linked to current international practices for the distribution of taxable profits will largely

remain. Differences in the treatment of debt- and equity-financing are likely to continue

to push up indebtedness and bear on growth. Differences in the treatment of debt and

equity across Member States will continue to offer tax planning opportunities.

Differences in R&D tax incentives will continue to prevent the emergence of a single

market for research, and promote tax competition strategies for the location of

intellectual property, without increasing R&D activities. As a consequence, socially-

inefficient levels of R&D may remain. Overall, as the internationalisation of the global

economy is expected to continue, it is likely that tax avoidance strategies will continue to

be sought after. In the long term, a shift to those avoidance strategies that are not at the

centre of the more recent policy proposals can be expected. Even new strategies might be

created, circumventing the new anti-avoidance rules and other measures that most likely

will be in place in the near future.

kom (2016) 0685 - Ingen titel

4.2.

Option 2: CCCTB with a scope definition

To keep the exposition reasonably simple, only the main options for the scope are

outlined below. Where relevant, sub-options on various design questions will be

discussed in Section 5.

4.2.1. Option 2a: Optional for all firms

Under this option, the CCCTB would be fully optional. Given the magnitude of tax

savings that are currently achievable for those companies that use tax avoidance

strategies most aggressively (see evidence in Table 1), it is unlikely that potential

CCCTB benefits such as reduced compliance costs, enhanced R&D benefits or cross-

border loss offset suffice to make these firms opt into the CCCTB. Consequently, a fully

optional approach would not effectively fight tax avoidance and is thus not suited to

enhancing the fairness of the tax system. This option is therefore not considered further

in the analysis of impacts in Section 4.

4.2.2. Option 2b: Compulsory application for a defined set of firms and

possibility to opt in for all others

This option would make the application of the CCCTB compulsory for a defined set of

companies, while giving all others the option to apply the CCCTB. The criteria for

defining the compulsory element should ideally capture companies which are most

relevant in the corporate tax avoidance context to comprehensively address corporate tax

avoidance in the EU and not introduce any undue selectivity. Several criteria can

theoretically be envisaged, alone or combined: (i) a sectorial approach, (ii) an approach

targeting multinational entities via a definition of cross-border groups and (iii) a size

approach.

4.2.3. Option 2c: Compulsory application for a defined set of firms without

possibility to opt in for other firms

This option would make the application of the CCCTB compulsory for certain

companies, but would not allow other companies to opt into the CCCTB system. While

such an approach would be in line with the objective of fighting tax avoidance in the EU,

this option is clearly problematic vis-à-vis the equally important objectives of stimulating

growth and investment and creating a level playing field. If the CCCTB delivers on its

promise to provide for a simple corporate tax system which would reduce compliance

costs and double taxation risks in the cross-border context, preventing some companies

from applying the system is not appropriate. Indeed, to the extent that the CCCTB could

provide more attractive design and compliance features than national tax systems, such

an approach may imply granting an advantage on a selective basis which would be

contrary to State aid principles. It may also raise concerns in terms of discrimination

under the fundamental freedoms. Finally, stakeholders who expressed their views widely

support a possibility to opt in. About 60% of respondents are in favour and only 9%

reject the idea. Some of the opponents explain their rejection with concerns about tax

planning possibilities. Not granting the possibility to opt-in is therefore not retained as an

option in the analysis of impacts in Section 5.

4.2.4. Option 2d: Compulsory application for all firms

This option would replace all existing national CIT systems with the single set of rules

provided by the CCCTB. Member States would continue to determine tax rates at

kom (2016) 0685 - Ingen titel

national level. Thus all corporations in the EU, irrespective of their size, group structure

or cross-border activity would have to apply the CCCTB.

4.3.

Option 3: Solutions to address the debt bias

4.3.1. Option 3a: No debt bias action

The no-action case assumes that the CCCTB does not provide any specific measure to

comprehensively address the debt bias. This implies that, as in the 2011 proposal, equity

costs are not deductible while interest expenses remain deductible, though with

limitations (notably those included in the Anti-Tax Avoidance Directive).

4.3.2. Option 3b: Non-deductibility of interest expenses

Disallowing the deductibility of interest expenses would align the treatment of debt and

equity costs.

With full non-deductibility of interest expenses, interest limitation rules

would become obsolete.

4.3.3. Option 3c: Allowance for corporate equity (ACE)

An allowance for corporate equity grants a defined return for equity which is deductible

from the tax base. The defined interest rate is usually close to or linked to a risk-free

reference rate such as the interest rates of government bonds.

Since the allowance is

computed by multiplying a defined rate on a definition of equity, an ACE does not

necessarily achieve full financing neutrality between debt and equity, but moves in any

case the system closer to neutrality.

The allowance can be designed in several ways. First, the allowance can apply to the total

stock of equity (stock-based) or to the difference between current equity and equity at a

specific date in the past (incremental-based). Second, the level of the defined rate can

vary with the reference interest rate. Third, the design can include anti-abuse measures to

avoid cascading of the benefits along the ownership structure of the corporate group.

4.3.4. Option 3d: Allowance for growth and investment (AGI)

The allowance for growth and investment is one specific version of an ACE. The AGI is

incremental with a moving reference date in the past. This means it is granted only for

the sum of equity increases over a specific period (e.g. 10 years in the past). Also, the

AGI foresees rules so that new capital can only benefit once from the deductibility.

4.3.5. Option 3e: Allowance for corporate capital (ACC)

Under this option, companies may deduct a defined return on total capital, i.e. the sum of

debt and equity. At the same time, it is no longer permitted to deduct actual interest

This option resembles a 1992 proposal from the U.S. Department of Treasury, called a Comprehensive

Business Income Tax (CBIT). However, the CBIT is more far-reaching as it complements the non-

deductibility of interest expenses with the non-taxation of interest income, an element which goes

beyond the EU's legal power to act.

The proposal goes back to a contribution by Devereux and Freeman (1991). It has been tested in

practice and with different designs. Currently, Belgium, Italy and more recently, Cyprus apply an

ACE. Austria, Latvia and Croatia also experienced an ACE. Portugal has an ACE for its SMEs (under

eligibility conditions) and is considering extending its scope. Other countries such as Turkey also

currently have an ACE.

kom (2016) 0685 - Ingen titel

expenses. Since there is only one rate applied to debt and equity, this option achieves full

financing choice neutrality.

The need for a limitation rule for the allowance would have

to be examined. So far, it has not been implemented in practice. The same considerations

in terms of stock versus incremental, the reference rate and the possible anti-abuse

measures apply as for the ACE and the AGI.

4.3.6. Option 3f: Cost of capital allowance (CoCA)

The cost of capital allowance combines a defined interest on capital at the corporate level

with the inclusion in the profit of the shareholder of an amount equivalent to the ACE

deduction obtained by the corporation and instead of actual dividends and interest.

The

CoCA is a far-reaching proposal that includes changes in the taxation of capital income

at the level of individuals. The option for a CoCA is not retained in the analysis of

impacts in Section 5 as it is too far-reaching. At corporate level, the effects of the CoCA

are identical to those of the ACC. The same considerations in terms of stock versus

incremental, the reference rate and the possible anti-abuse measures apply as for the ACE

and the AGI.

4.4.

Option 4: Options to incentivise R&D

R&D tax incentives reduce the tax burden on R&D activities. They can target R&D

inputs by supporting R&D related expenditure. Such measures either reduce the tax base

by granting a deductible allowance or they directly reduce the amount of tax to be paid in

form of a tax credit. Support measures can also be based on output, i.e. income generated

by R&D outcomes such as patents. The latter offer reduced rates on R&D income.

4.4.1. Option 4a: No further action on R&D

The no-action option assumes that, as in the 2011 proposal, all R&D expenses would be

expensed immediately for tax purposes. However, to reflect concerns expressed by

Member States in Council, it is also assumed that capital expenses on R&D buildings

would not be expensed immediately, but depreciated in the same way as other

buildings.

No national R&D tax incentives would apply any more for companies

applying the CCCTB.

4.4.2. Option 4b: Granting tax incentives for R&D expenses

Under this option, the CCCTB would offer additional allowances or tax credits on R&D

expenses, replicating tax incentives applicable under the national systems.

4.4.2.1. Additional allowance for R&D expenses

An additional allowance decreases the tax base by deducting more than 100% of R&D

expenditure.

For example, a company could deduct an additional allowance of 50% of

An ACC was first analysed by Boadway and Bruce (1984).

This system was proposed by Kleinbard (2015).

R&D expenses on buildings and land account for only a small share of total business R&D (around 5%

according to OECD estimates) and are therefore not expected to materially affect incentives to invest

in R&D. The largest part of R&D spending is for skilled labour which also generates the highest

spillovers.

Note that the term "additional allowance" in the context of R&D refers to the amount of tax incentives

granted on top of immediate expensing of R&D expenditures, i.e. an immediate deduction of 100%. In

kom (2016) 0685 - Ingen titel

their R&D expenditure on top of the full deductibility of R&D costs, i.e. 150% in total.

The effective level of generosity of the additional allowance varies with the applicable

corporate tax rate.

4.4.2.2. Tax credit for R&D expenses

Tax credits and additional allowances are economically very similar. The operational

difference is that tax credits reduce directly the tax bill and therefore do not vary with the

tax rate. However, tax credits go beyond the scope of the common base. Member States

would give a tax credit after the computation of the tax liability which would be in

opposition to the spirit of the CCCTB. By granting a tax reduction after the application of

formula apportionment they would not ensure a level playing field for R&D in the EU

and could induce harmful competition between Member States.

Therefore this option is

not retained.

4.4.3. Option 4c: Granting tax incentives for income from intellectual

property

Output-related incentives apply reduced rates to income generated by R&D, i.e. earned

from exploiting intellectual property (patent boxes). The empirical evidence suggests that

input-related incentives are more effective than patent boxes in stimulating R&D

investments.

Moreover, patent boxes have in recent years given rise to concerns of harmful tax

competition. First, intangible assets play an important role in profit shifting as their

location can be tax sensitive and can lead to large revenue losses.

Evidence from ZEW

(2016c) as summarised in Table 1 shows the considerable decrease in effective tax rates

that multinational groups can achieve by exploiting patent box regimes. Second, patent

boxes do not stimulate increases in R&D activity.

Third, there is no clear rationale for

using patent boxes as a means of stimulating innovation, as they do not appear to address

any specific market failure. Instead, they award additional tax benefits to a successful

innovation that already enjoys intellectual property protection. Research efforts that are

not patentable with potentially higher social spillovers are less attractive and thus become

indirectly discriminated. Finally, the compliance costs required to directly link R&D

expenses to individual patentable efforts are significant and extremely complex for

businesses and tax administrations.

All in all, this option does not only go contrary to the objective of reducing tax avoidance

and improving the fairness of the tax system, but also against the objective of stimulating

additional research and innovation and simplifying the tax system. It is therefore not

retained for further analysis.

4.5.

Option 5: Staged approach

Recognising the likely difficulties to adopt the CCCTB in one step, the June 2015 action

plan announced that consolidation and formula apportionment would be postponed until

the common base has been agreed and implemented. This impact assessment therefore

assesses the implications of such a staged approach. The key question concerns the

granting of some form of cross-border loss relief in the absence of consolidation.

It is useful to note here that there will be no differentiation between stage 1 (CCTB) and

stage 2 (CCCTB) regarding the scope and the definition of the tax base (including the

debt bias solution and the R&D incentives). The directive on a common base would be

implemented as a first step and then be amended in stage 2 via a CCCTB directive to

incorporate consolidation and formula apportionment. The base definitions as such do

not change in stage 2.

4.5.1. Option 5a: Common base without cross-border loss relief

This option focusses on securing the common tax base at a first stage. This would

involve agreeing to a common set of corporate tax rules for computing the tax base of

companies without possibility for multinational entities to offset losses in one Member

State with profits in another Member State.

4.5.2. Option 5b: Common base with cross-border loss relief

With the aim to strengthen EU competitiveness, the common base could include a

mechanism of (partial) cross-border loss relief with subsequent recapture. Taxpayers

would be entitled to temporarily take into account the losses incurred by their immediate

subsidiaries and permanent establishments situated in other Member States.

under the patent box and a firm’s R&D activities ('nexus approach'). However, this does not mean that

these schemes are effective in raising R&D efforts.

NALYSIS OF IMPACTS OF THE OPTIONS

This section assesses the options outlined above in terms of their effectiveness and

coherence in reaching the specific objectives, which contribute to the general objectives

of enhancing fairness and stimulating growth and investment. Fairness of the tax system

is measured mainly against the effectiveness of the option to limit tax avoidance in the

future. The assessment involves a qualitative evaluation on the suitability of options to

prevent the most relevant cross-border tax planning strategies, as well as a quantification

of the impact on profit shifting in the EU. Stimulating growth and investment is assessed

vis-à-vis the specific objectives outlined in Section 3.2. Simplification is achieved to the

extent that complexity is effectively reduced. The impact on financing distortions is

assessed in terms of the change in the debt bias, which is measured here as the difference

in the cost of capital of an investment if financed by equity or debt. Investment

distortions are measured in terms of the impact on the average cost of capital of

investments. The main options are also assessed in terms of their impact on the economy

in a general equilibrium model. Main variables looked at include GDP, investment,

employment and wages and welfare. Finally, the section discusses the expected impact

on tax revenues and on the burden for companies and administrations as a result of

implementing the different options.

The coherence assessment focusses on evaluating whether fairness and tax avoidance

objectives are indeed not achieved at the expense of stimulating growth and investment

and vice versa.

kom (2016) 0685 - Ingen titel

To reduce complexity, the assessment is presented in sequential steps. This separation of

option dimensions is justified as there are no relevant interdependencies between them.

Other possible interdependencies are discussed whenever appropriate; otherwise the

independence between different option dimensions is explained in the following

subsections. Sections 5.1 and 5.2 focus on the basic choice of 'no action' versus

implementation of a CCCTB and the options on the scope of the application. Assuming

implementation of the CCCTB with the preferred scope option, Sections 5.3 and 5.4

assess the open design issues related to debt bias and R&D incentives. Finally, Section

5.5 assesses the impact of introducing the CCCTB in two steps, with an initial period

without consolidation, but possibly with some form of cross-border loss relief.

Box 2: Formula apportionment

The distribution of revenues based on a formula is an important element of the CCCTB proposal and its

impact was analysed in the 2011 impact assessment (see also annexes V and VIII). It concluded to

allocate the consolidated tax base to a 'group member A' according to the following formula:

Aside from the extensive work by the CCCTB Working Group and consultations with stakeholders,

three specific pieces of analysis were included in the impact assessment in order to compare the impact

of different formulas: (i) a survey of multinational entities on compliance costs: (ii) impact of

variations in the formula on the distribution of tax bases across countries, using the Amadeus and

ORBIS databases; and (iii) the CORTAX study, which examined formula apportionment within the

context of a wider analysis aiming to quantify the impacts of alternative policy options. The formula

was evaluated against four criteria: 1. Simplicity for taxpayers and administrations; 2. Difficult to

manipulate, i.e. no easy relocation of factors to exploit tax-rate differentials across the EU; 3. Fair and

equitable distribution of the tax base; 4. No negative impact on tax competition. More details on the

rationale for the formula that was chosen can be found in Annex V: Formula apportionment.

Figure 7 shows the sequence of the analysis. To justify this sequential approach it is

required that the preferred options for the scope, for the debt bias solution and for R&D

incentives do not change if the choice of options changes for the other dimensions. Based

on the available analytical evidence and qualitative arguments this can be assumed with

relative confidence. For example, the choice of a solution for addressing the debt bias

seems independent of the choice for the scope or of the choice for the R&D incentives.

In contrast, this does not mean that the choice of each dimension does not affect the final

outcome. In other words, the economic impact of a preferred option (for example to

address the debt bias) might very well change if options in another dimension change (for

example the mandatory scope). For example, implementing an AGI for all companies or

only a selection of them will have different economic impacts. However, the important

point is that the ranking of the preferred options seems to be independent from the

choices made elsewhere.

However, it should be made clear that it is not possible to quantify in all cases the exact impacts due to

the limitations of the analytical model, even if this latter is considered state-of-the-art in corporate

taxation analysis in an international context. Based on the partial analysis that is available on the

combination of certain options and based on additional quantitative arguments outlined in the analysis

Baseline vs CCCTB

This section compares the CCCTB (option 1b) with the baseline scenario (option 1a),

assuming that the CCCTB will be either (i) mandatory for some set of firms with the

possibility to opt in for others or (ii) mandatory for all firms. To keep the exposition

reasonably simple, this section discusses the case of a CCCTB without any specific

measures to address the debt bias or to ensure sufficient incentives for R&D. Since there

is a certain degree of overlap of the present assessment with the impact assessment of the

2011 proposal, the main conclusions of the 2011 assessment have been summarised in

annex VIII.

5.1.1. Fairness impacts

Despite the progress at EU level in coordinating a stronger anti-abuse framework, it is

clear that these new rules alone do not address comprehensively the roots of the problem,

particularly in the long term. The inherent conflict remains between corporate taxation

rules determined at national levels on one hand and an increasingly integrated economy

and mobile profits on the other hand. As such, there is a risk that the new anti-abuse

below, one can be confident that the principal choices (i.e. limiting the mandatory scope to large firms,

opting for an allowance for growth and investment to address the debt bias, providing additional

allowance for R&D expenses) would not change even if a complete model that could capture all the

interactions were available.

kom (2016) 0685 - Ingen titel

framework addresses only a selection of avoidance strategies, so that companies over

time would adjust their behaviour towards other planning strategies. Not only would this

entail the need for new anti-abuse rules and an ever more complex system, it would also

mean that tax planning multinational entities will keep their undue advantages vis-à-vis

purely domestic firms.

Due to the common rules for determining the tax base combined with full consolidation,

the CCCTB would by and large eliminate profit-shifting possibilities within the EU for

those companies subject to mandatory application. Notably, aggressive tax planning by

exploiting mismatches and making use of patent boxes would no longer be possible,

provided that due attention is given to definitions of central concepts such as debt,

interest expenses, profits and dividends. Whereas exploiting tax differentials via intra-

group loans or transfer pricing would no longer be beneficial. Effectively, the most

relevant aggressive tax planning strategies would be addressed within the EU.

Incentives for tax planning remain however relevant vis-à-vis third countries. Therefore,

the CCCTB is equipped with a broad set of anti-avoidance measures. As discussed

above, many of these measures are already adopted with the Anti-Tax Avoidance

Directive. Hence, anti-abuse rules addressing tax avoidance involving third countries

would be harmonised with a CCCTB which leaves companies with less room to shop for

the most attractive regime(s) in the EU.

Limited opportunities would remain in relation

to differences in withholding tax regimes between EU Member States and third countries,

with respect to factor allocation under the formula apportionment regime and, if the

mandatory application is not extended to all firms, with respect to those companies or

parts of a company group that are not subject to the CCCTB.

Also, transfer pricing

remains an issue between the EU and third countries.

In the general equilibrium model used to analyse the economic impacts of a CCCTB

reform,

multinational entities have the possibility to shift profits within their group via

transfer pricing.

Table 4 below compares the impact of profit shifting on tax bases in

the baseline case and in the CCCTB case (compulsory for multinational entities). The

table shows the percent changes in the tax base due to intra-group profit shifting from

and into EU Member States. The starting point is the hypothetical tax base that would

occur if transfer pricing was not available to multinational entities. In the model, which

covers the EU-28, the US and Japan, the CCCTB results in the complete elimination of

any outward shifting of profits from EU Member States. Inward shifting is also largely

eliminated although some inward shifting from the high-tax countries US and Japan

remains. CORTAX currently cannot simulate other aggressive tax planning techniques.

To the extent that these are no longer possible or beneficial within the EU under the

See Ramboll et al. (2015) for a description of those tax planning strategies.

The relevance of this point is underlined by the findings in ZEW (2016c).

See annex V for a discussion.

See annex IV (part 1) for a detailed description of model.

CORTAX does not model other tax planning strategies, which are often based on specific regimes

offered in national tax systems or certain mismatches between national systems. Therefore the analysis

of the profit shifting impact is stylised and summarised via the transfer pricing channel. In addition,

the analysis only covers profit shifting within the EU, the US and Japan. Consequently, the figures

presented here are not comparable with the estimates presented in Section 2 on the possible tax

revenue costs of tax avoidance.

kom (2016) 0685 - Ingen titel

CCCTB, notably strategies using mismatches, intra-group loans and patent boxes, similar

relative impacts can be expected.

Overall, in terms of effectively addressing tax avoidance, the CCCTB has very clear

advantages compared to the 'no action' scenario.

Due to the reduced tax planning opportunities, governments will face fewer difficulties in

ensuring a fair contribution to tax collection from the corporate sector. Under a formula

apportionment mechanism as described in box 2 (but in the absence of rate

harmonisation) planning opportunities may still theoretically arise because of the

incentive to relocate the apportionment factors included in the formula and hence

attribute the largest possible share of their profit to low-tax Member States. For instance,

multinational entities may engage in 'factor shifting' operations by structuring sales

through 'independent' distributors located in low-tax Member States. However, the

literature confirms that the envisaged formula apportionment system is much less prone

to such artificial arrangements than the current system because shifts of real factors are

generally more difficult and costly to do than shifts of book profits.

The application of

anti-abuse and related provisions in the CCCTB further reduces this possible avoidance

issue.

Moreover, the optimal location of factors depends on many determinants other than taxes

(such as infrastructure quality, availability of skilled work). In addition, the possibility to

opt into the system for companies outside the mandatory scope mitigates risks of tax rate

competition, as a country that lowers the tax rate applicable to the CCCTB would risk a

larger deterioration of revenues as more and more companies would opt in. It is therefore

expected that the problems that Member States face today with mobile tax bases and the

ensuing tax competition will not persist within the EU under the CCCTB with formula

apportionment.

The effective reduction of tax planning activities is expected to have a positive impact on

taxpayer morale. Over the past years, more and more large-scale tax avoidance cases

have become publicly known. This is damaging as it may impact taxpayer compliance

more generally. It is known that social norms may influence the compliance behaviour of

taxpayers. To the extent that tax avoidance cases reveal poor tax ethics, i.e. a poor sense

of responsibility for contributing a fair share to society, this might negatively impact on

the ethics of other taxpayers. Moreover, taxpayers without tax planning opportunities

may perceive this as unfair and feel a moral justification to not fully comply with their

obligations. Indeed, several studies support the view that a perception of unfairness in

See Annex V: Formula apportionment.

kom (2016) 0685 - Ingen titel

taxation negatively impacts tax compliance behaviour or at least the willingness to

cooperate with tax authorities.

5.1.2. Economic impacts

To assess the economic impact of various options, the CORTAX model was used.

CORTAX is a computable general equilibrium model, allowing state-of-the-art analysis

of corporate tax reforms by incorporating key features such as multinational profit

shifting, investment decisions, loss compensation and the debt-equity choice of firms.

The model includes the direct and indirect effects of all domestic labour and capital

markets. It covers the 28 countries of the European Union, the U.S., Japan and a tax

haven. The CORTAX simulations assess the impact of the CCCTB on a set of main

economic variables such as investment, employment and wages, GDP and welfare. It is

assumed that the CCCTB is implemented in a budget-neutral manner, notably by

compensating changes in the corporate tax base by changes in the CIT rate.

Results can

be made available for two basic assumptions on the set of firms applying the CCCTB:

either all firms or only multinational entities. The assumption that all multinational

entities apply the CCCTB fits, within the logic of the model, to a wide range of possible

definitions for the mandatory scope as long as domestic firms are not included.

Table 5 shows the results of implementing the CCCTB for multinationals only and for all

firms (both compared to the baseline scenario). Whether applied to multinational entities

only or to all firms, the CCCTB has positive effects on key economic variables. The cost

of capital decrease and as a result investment increases. Employment and wages are also

positively affected, as is GDP and welfare. The results for CCCTB for all firms are

generally more positive, albeit the differences are marginal.

As a caveat, CORTAX does not permit a proper assessment on the level playing field

between domestic firms and multinational entities. On the one hand, the closing of the

Niemirowski and Wearing (2006) and Torgler et al. (2008).

In more detail, the model adjusts ex-ante the corporate statutory tax rates to ensure ex-ante revenue-

neutrality when the corporate tax base changes. The adjusted CIT rate is subject to an upper bound for

of 37.5% and a lower bound of 10%. In addition, budget neutrality is ensured ex-post by a change in

lump-sum transfers to the citizens (see JRC (2016) for the details).

European Commission (2016) are available in annex IV.

most important cross-border tax planning channels is not properly reflected in the model.

CORTAX captures profit shifting in a stylised way through transfer pricing via intra-

group sales, but does not feature multinational entities exploiting mismatches, making

use of patent boxes or saving taxes via intra-group loans. On the other hand,

multinational groups in the model benefit considerably from consolidation. This is

mostly because they are all active in all 28 Member States, which makes it very likely

that a loss occurred in one Member State can be offset against profits in other Member

States. Thus, the model tends to capture more the positive features for multinational

entities while the loss of tax planning opportunities is reflected only partially. In contrast,

the possible positive impact on domestic firms is not captured in the model. This is

because CORTAX does not feature the opt-in choice of firms. In the 'only multinational

entities' case, domestic firms are assumed to stay in their respective national system,

which is broadly consistent within the logic of the model. In the 'all firms' case, domestic

firms are all forced into the CCCTB. In both cases, there may be reasons that domestic

firms would rather opt into/stay out of the CCCTB. For example, if for a domestic firm

the CCCTB tax base is smaller compared to the national tax base and this advantage is

not fully eliminated by a larger CCCTB tax rate, a domestic firm might choose the

CCCTB. The CCCTB may also be attractive as it may be simpler to administer than the

national system, notably due to the depreciation regime, which allows depreciating short-

life assets in a pool rather than individually.

Hence, the model may over-emphasise the positive impacts of the reform for

multinational entities, whereas it may underestimate them for domestic firms. Moreover,

this relative difference in the impacts is reinforced to the extent that domestic firms and

multinational entities compete against each other. As a result, the CORTAX simulations

show a large increase in production of multinational entities and a large decrease in

production of domestic firms, as reported in Table 6. Due to the caveats explained above,

and notably since the model does not feature the possibility to opt in for domestic firms,

the magnitude of the estimated impacts on production cannot be considered realistic. It

therefore does not seem justified to reject the proposal based on this result alone.

opt in, even if in reality they may prefer to do so.

A sensitivity analysis based on a number of variations in the assumptions has been

conducted. The variations that have been considered include different depreciation

regimes, variation in the capital-labour substitutability, reduced compliance cost savings

under the CCCTB and compensating changes in tax bases by modifying labour taxes

instead of corporate income tax. All variations yield similar results as in the central case,

pointing to the robustness of the findings, namely positive economic impacts.

Impacts on tax revenue

The CORTAX simulations also allow for some first considerations on the impact on tax

revenues although the model cannot simulate all transmission channels. The available

simulations point to a small decrease in total tax revenues for the EU-28 of 0.08% of

GDP, corresponding to about EUR 11 billion. This results from a decrease in EU-28

corporate tax revenues by about EUR 36 billion partly compensated by increases in the

collection of other taxes by about EUR 25 billion. These tax increases are due to

increased economic activity and better employment that respectively boost consumption

and labour tax bases.

These figures should be put in perspective with the potential gain in corporate tax

revenues due to the reduction in several forms of corporate tax avoidance. As discussed

in the previous subsection, the CORTAX model captures the impact from reduced

transfer pricing activities (which are eliminated in the model), but it does not capture the

removal of patent boxes, the removal of hybrid mismatches and the elimination of profit

shifting via intra-group debt shifts. A recent study commissioned by the European

Parliamentary Research Service finds that the corporate tax revenue losses due to tax

avoidance would amount to about EUR 50-70 billion in the EU. It is however difficult to

assess the share of this amount due to transfer pricing and the share due to other

channels.

Moreover, interpreting these values is difficult as a number of factors impact on

revenues. Most importantly, the model assumes that governments set the CIT rate for the

CCCTB in order to compensate for changes in the rules to compute the corporate tax

base. This is a technical assumption as national governments would be free to adjust tax

rates in other ways. More details and a discussion of other factors that drive the impact

on tax revenues are provided in annex XII.

Impact on administrative burden

The effectiveness of the CCCTB in simplifying the currently highly complex

international system of corporate taxation, reducing compliance costs and double taxation

and removing discriminations and restrictions in cross-border situations, has been

demonstrated in the 2011 impact assessment.

To which extent the CCCTB would be

made mandatory is of little relevance for these impacts as companies or company groups

which would gain the most from reduced compliance costs are expected to opt into the

system. The differences in national R&D incentives schemes (as illustrated in annex XI)

are a good example to illustrate the potential for simplification. These differences can

lead to high compliance cost for businesses that conduct their R&D cross-border or

engage in transnational cooperations on R&D projects for example through joint

ventures.

As explained in annex VII, tax compliance costs remain an important burden for

businesses and their reduction is a major advantage of the CCCTB compared to the

Available studies on the tax revenue impact from transfer pricing do not give a clear indication. The

staff working document accompanying the June action plan includes a summary discussion of the

available studies (SWD/2015/121).

See annex VIII for an overview.

baseline. The 2011 impact assessment estimated compliance costs for large companies to

amount to about 2% of taxes paid, while for SMEs the estimate was about 30% of taxes

paid. In absolute terms, compliance costs were estimated to increase with cross-border

activity and with increasing number of subsidiaries. The compliance cost levels and their

structure do not seem to have changed considerably in recent years. A recent review of

compliance tax studies (Eichfelder and Vaillancourt, 2014) shows for the period from

1984 to 2014 that compliance costs remain largely stable over time. Existing differences

between different estimates are rather due to different methodologies applied to measure

the costs.

One could expect that compliance requirements have rather slightly increased since the

2011 assessment. In fact, tax reform data show that numerous CIT reforms took place

after the crisis and many measures were directed at reinforcing the international anti-

abuse framework.

In the light of this, the reduction of compliance costs when setting up

an additional subsidiary under the CCCTB remains a major advantage: Time costs for

setting up a new subsidiary in a Member State were estimated to decrease 62-67% for the

CCCTB. Focussing on recurring costs, i.e. ignoring one-off switching costs, the 2011

impact assessment estimated a decrease in time spent on compliance activities by 8% for

the CCCTB.

Based on these time reductions one could endeavour a rough calculation

of the order of total cost savings that would result under the CCCTB. If 5% of medium-

sized companies expand abroad, a one-off cost saving of around EUR 1 billion could be

expected. If all multinational entities apply the CCCTB recurring compliance costs could

go down by about EUR 0.8 billion.

Tax administrations will benefit from reduced dealings with transfer pricing issues and a

reduced 'case number' to the extent that the tax affairs of a company group is mainly dealt

with by the administration of the Member State where the parent resides. However, if the

CCCTB is not made mandatory for all firms, the burden for national administrations may

go up slightly due to the required maintenance of two parallel systems. Also, there might

be requirements to set-up new IT and communication systems between Member States to

ensure a consistent enforcement and application of the CCCTB.

5.1.3. Stakeholder views

Most of the stakeholders (38%) believe that the CCCTB can be an effective tool against

aggressive tax planning and at the same time retain attractiveness to businesses. This

includes a majority of enterprises, driven by the views of SMEs, 54% of which agree

with this view. Another 22% of stakeholders have a more nuanced opinion. A number of

them give a qualified approval, i.e. attaching certain conditions; others point to the

original motivation of removing single market barriers, which in their view should

remain the main focus. Some 17% of respondents do not believe in the effectiveness of

The Commission services commissioned a study (Ramboll Management Consulting et al., 2013) on

methodologies to measure compliance cost in 2013 which explains in detail the existing methods as

well as the related caveats.

The Tax Reform Report 2015 describes the very recent anti-avoidance measures taken by Member

States in the 2014 and 2015 (Section 1.5.2 of the report). For example, several Member States

introduced or strengthened general or specific anti-avoidance provisions. Four Member States

reinforced their transfer pricing rules, in particular by extending reporting requirements. Controlled-

Foreign-Company rules were introduced or tightened as were interest limitation rules.

the CCCTB against aggressive tax planning. Often they point to other initiatives against

tax avoidance and/or do not find the CCCTB to be a proportionate measure.

5.1.4. Preferred option

Overall, the CCCTB (option 1b) is preferable over the alternative of taking no action

(option 1a). The anticipated effects of enhancing fairness via reduced corporate tax

avoidance, ensuring a fair tax contribution from the corporate sector, a more level

playing field among companies and the expected positive impacts on taxpayer morale are

critical, even if not all of them are quantifiable. This is also in line with the views of a

majority of stakeholders. In addition, small positive economic impacts are expected

through the removal of single market tax obstacles. Both the business environment and

the labour market are positively affected. Overall, welfare is expected to increase

slightly. The removal of tax obstacles is also expected to remove existing distortions

between domestic and cross-border investments and enhance incentives for cross-border

investments within the EU and form outside the EU.

Moreover, the administrative burden for companies operating cross-border is expected to

reduce significantly. The burden for national administrations is expected to go down if

the CCCTB is made mandatory for all firms. If not, the required maintenance of two

parallel systems in case the CCCTB is not made mandatory for all companies could raise

the costs for administrations.

Scope of the common consolidated base

This section will examine the options for the scope of the mandatory application, keeping

in mind that it is motivated by the new objective of enhancing the fairness of the tax

system by comprehensively addressing corporate tax avoidance. The available options

are to make the application compulsory for all firms (option 2d) or to make it compulsory

for some firms (the scope of which will be discussed) and to grant the possibility to opt

in for other firms (option 2b). Full optionality (option 2a) as well as making the CCCTB

mandatory for some set of firms without granting the possibility to opt in for other firms

(option 2c) have been discarded in Section 4.2.

5.2.1. Fairness impacts

To determine the mandatory set that is effective in capturing tax avoiders but

proportionate at the same time, i.e. not imposing unjustified obligations, it is helpful to

think of three mutually exclusive sets of firms. First, there are those firms that prefer the

CCCTB over the current national systems. It is irrelevant whether the mandatory

application applies to these firms as they will in any case benefit and therefore opt into

the CCCTB. Second, there are firms that prefer the current national systems, not because

they are currently employing tax avoidance strategies but because the net impact from the

CCCTB is not positive for them, in the sense that it would increase their tax burden and

they would not benefit sufficiently from reduced compliance costs. Third, there are firms

that prefer to continue applying the current national systems because they benefit from

tax avoidance strategies and this benefit is larger than any potential benefits from reduced

tax compliance costs and the net impact of other changes.

It is not relevant whether the definition of the mandatory set covers firms in the first set,

which in any case would opt-in. However, the aim should be that the definition captures

the third set of firms and should only capture firms in the second set if there is a valid

justification for requiring them to apply the CCCTB. Many firms in the second set are

likely to be micro and small corporations. These smaller firms are unlikely to engage in

tax avoidance practices. Since a large share of them are active only domestically

, they

would also not be able to reap any of the potential benefits of the common base. In

addition, 14 Member States currently apply specific regimes for the smallest

corporations, not only in the form of reduced statutory rates, but in 11 of them also via

modified tax bases and/or relief from other taxes.

The mandatory for all option would

harmonise the tax treatment across all firms. It is not clear whether this would necessarily

create a level playing field to the extent that special regimes are justified to compensate

undue competitive disadvantages. The results from the CORTAX study for the

'mandatory for all' option presented in Table 7 indicate that in the aggregate domestic

firms (which may be small or not) do not benefit uniformly from the application of the

CCCTB.

Overall, option 2d to make the CCCTB mandatory for all firms appears disproportionate

to the extent that it would unnecessarily oblige these small and micro corporations to

To keep the structure of the assessment of various option dimensions consistent throughout the report

the impact analysis in this section is divided into fairness impacts and economic impacts, even though

the separation is not always clear-cut.

According to a survey conducted in 2015, only 4% of European SMEs had invested abroad at that time

(European Commission (2015c)). Similarly, Navaretti et al. (2011) find a clear positive correlation

between firm size and propensity to invest abroad in seven EU Member States (AT, FR, DE, HU, IT,

ES, UK). Notably, the share of firms with foreign affiliates is several times larger for large firms than

for SMEs.

kom (2016) 0685 - Ingen titel

apply the CCCTB. Proportionality is also an important aspect of the EU Better regulation

agenda and in particular its programme for regulatory fitness (REFIT), according to

which legislation should avoid any unnecessary burden. In line with this approach, the

intention is thus not to place, in the absence of any real benefits, a burden on smaller-

sized companies of limited finances, which may not have the intention of expanding

abroad. While this would come at the administrative cost of maintaining two corporate

tax systems in parallel, it would also allow national corporate tax systems to stay more

flexible and respond to domestic circumstances.

There are in principle three main criteria that could be used to select firms into the

mandatory set: (i) a sectorial approach, (ii) an approach targeting multinational entities

via a definition of cross-border groups and (iii) a size approach.

Sectorial approach

One could argue that some sectors, such as the financial sector, would be more suitable

candidates than other sectors to the application of a CCCTB, notably because the far-

reaching harmonisation in regulation and supervision makes taxation one of the few

discriminating elements between companies of different Member States.

However, the

sectorial approach is not retained here as the problems identified in Section 2 are

common to all sectors, albeit to possibly varying degrees, and as it is difficult to

apprehend how an adequate and efficient solution to those problems can be achieved by

applying a sectorial approach.

Cross-border criterion

Firms that currently benefit from cross-border tax planning have by definition a cross-

border structure. This is therefore a natural requirement for the inclusion into the

mandatory set. It may be considered as the 'minimum criterion', leading to the widest

mandatory scope that is justifiable. However, mandating firms with cross-border

operations into the CCCTB while domestic firms (even of a comparable size) are given

the possibility, but are not obliged, to opt in, could be challenged on discrimination

grounds. In addition, if not complemented by further criteria a cross-border criterion

would capture about 4-5% of SMEs that are active cross-border (Table 8 below). On this

basis, it is not suggested to focus on a cross-border criterion alone.

Size criterion

There is a clear correlation between size and propensity to operate in a cross-border

structure (Table 8 below). Therefore, applying a size criterion might be a good alternative

way for capturing those – essentially cross-border – businesses which have higher

possibilities of engaging in tax avoidance practices. Furthermore, relying on a size

criterion would better fit the necessity to avoid discrimination since it would not make

any difference between a member of a multinational group and a member of a domestic

group that, even just potentially, want to grow internationally or do business through

permanent establishments. Finally, a size criterion would be consistent with the approach

followed in the recently agreed amendment to the Directive on administrative

See e.g. Bénassy-Quéré, Trannoy and Wolff (2014).

kom (2016) 0685 - Ingen titel

cooperation to implement the country-by-country reporting. The reporting requirement

will apply to groups with total consolidated revenue of at least EUR 750 million.

Different size thresholds could be envisaged above which the CCCTB would be

mandatory. In that respect, the following elements serve as guiding principles.

First, as explained above, the threshold should aim at the right balance between the risk

of tax avoiders falling below the CCCTB threshold and the risk of imposing the CCCTB

to companies that do not engage in tax avoidance and would get little or no benefit from

lessened compliance costs as they do not operate cross-border (i.e. threshold set too

low).

The available evidence on the link between a firm's size and its likelihood to engage in

tax planning would point, if anything, to a rather high threshold. It is difficult to establish

a clear direction for this link. The empirical literature finds evidence for both positive and

negative relationships, pointing to a possible non-linear relationship. A recent meta-study

by Belz et al. (2016) finds the overall effect to be rather positive. However, they also

point to a changing picture based on studies that use more recent samples. Moreover,

studies focussing on samples with larger firms show a significantly lower consensus

estimate, indicating that these firms might indeed achieve lower effective tax rates. Data

for the US show that average implicit tax rates (i.e. the tax payment divided by the

taxable profit) increase with increasing firm size, except for the 5% largest firms.

Examining this upper 5 percentile more closely shows that there is no significant trend in

one or the other direction for the 95-99 percentile but that effective tax rates are

significantly lower and decreasing in size for the 99-100 percentile (Bao and Romeo,

2013).

Analyses of the structure of tax compliance costs of companies suggest that spending on

tax planning increases with firm size which could be interpreted as economies of scale in

tax avoidance techniques. Eichfelder and Vaillancourt (2014) summarise the tax

compliance cost literature of the last three decades and conclude that tax planning costs

seem to be relatively unimportant for micro and small enterprises. The results could be

interpreted in the sense that the fraction of planning costs increases with business size.

This evidence has to be used cautiously due to the many weaknesses of the methods to

estimate compliance costs and the exact definition of tax planning costs. Data provided

by Slemrod and Venkatesh (2002) show that the share of tax planning costs in total

compliance costs increases with firm size measured by the value of assets from 4% for

companies with assets smaller than USD 5 million to 15% for companies with an asset

size of more USD 1 billion.

Second, by setting a threshold, a trade-off might emerge for some companies that may

want to scale down or refrain from growing in order to remain outside the scope of the

CCCTB. Such an effect is likely to be more acute if the threshold is low. The direction of

In the OECD/G20 BEPS Report on Action 13, the following elements were put forward: the general

filing requirement for MNE groups with annual consolidated group turnover of more than EUR 750

million is believed to "exclude approximately 85 to 90 percent of MNE groups from the requirement to

file the country-by-country report, but that the country-by-country report will nevertheless be filed by

MNE groups controlling approximately 90 percent of corporate revenues. The prescribed exemption

threshold therefore represents an appropriate balancing of reporting burden and benefit to tax

administrations." (OECD, 2015b)

kom (2016) 0685 - Ingen titel

the distortion would be that some firms above, but close to the frontier would stay

smaller than they would choose to be otherwise.

Unless at the outset firms are already

larger than optimal, this would imply an efficiency loss. The lower the threshold, the

larger is the number of firms facing such a trade-off. A similar issue concerns the level

playing field between companies below and above the threshold. Due to the possibility to

opt in, firms below the threshold may be able to benefit from an advantage compared to

competitors above the threshold. This concern is less pronounced for higher thresholds

simply because there will be fewer instances of direct competitors being below and above

the threshold.

Third, a very high threshold may give rise to concerns of creating a beneficial tax regime

for the most mobile segment of the tax base, which would in turn harm taxpayer morale.

In principle, Member States would have incentives to make the CCCTB regime attractive

to attract mobile base. There are two reasons why this concern is of limited relevance.

The notion of mobility will change under the CCCTB as shifting tax base requires the re-

allocation of factors. Furthermore, the possibility for companies to opt in implies that a

country that lowers the CCCTB tax rate would risk a larger deterioration of revenues as

more and more companies would opt in.

Table 8 gives an overview of the estimated scope of the CCCTB (in terms of number of

companies and share of corporate revenues) for various thresholds.

It is clear that corporate groups with consolidated turnover up to EUR 50 million, which

corresponds roughly to SMEs, are overwhelmingly present in a single Member State

only. Therefore, capturing the small share of SME groups active in more than one

Member State would come at the expense of imposing a change to the CCCTB on a very

large number of domestic firms. This would clearly not be a targeted measure. Moreover,

even within the large groups with consolidated turnover of more than EUR 50 million,

slightly more than half of the large groups have a purely domestic structure. The share of

domestic firms becomes significantly smaller only for considerably larger thresholds.

Overall, the thresholds of EUR 500 million and EUR 750 million seem to produce fairly

requirements in Japan.

This ratio has been computed for groups that have their global ultimate owner (GUO) in the EU. In

They imply that a fraction of 19.2% and 24.5% of groups under mandatory application

would be active only domestically.

5.2.2. Economic impacts

Results for the economic impacts using the CORTAX study have been obtained for two

different assumptions on the set of firms that apply the CCCTB, namely either only

multinational entities or all firms. As the results summarised in Table 4 and Table 5

show, the overall impact on key economic variables is very similar for the two options.

However, the CORTAX model is not built to capture in a meaningful way the opt-in

decision of a firm. The assumption that all multinationals opt into the CCCTB, whereas

domestic firms prefer to stay out is consistent with the other assumptions in the model,

but in reality a number of elements influence the opt-in decision.

In principle, one would expect economic impacts to be maximised if firms have the

largest possible flexibility to choose the CCCTB. They would then self-select depending

on whether the CCCTB or the respective national system better fits their needs, even

though this would also entail a certain burden due to the required cost-benefit analysis

preceding such a decision.

Impact on administrative burden

The main impacts on the compliance burden for companies have been discussed in

Section 5.1. In principle it is expected that the CCCTB reduces the compliance burden

for companies, at least for those that are active cross-border or wish to expand cross-

border. There may be cases in which a company finds the respective national system

easier to deal with. If companies have the possibility to opt into the CCCTB, they would

factor in the compliance burden in their opt-in decision. In this respect a wider optional

application would be better to reduce compliance costs. On the other hand firms would

have to conduct a cost-benefit analysis before they decide. Since such cost-benefit

analysis is a one-off cost, it is overall more beneficial from a compliance cost perspective

to leave companies a choice.

Tax administrations, however, would benefit the most if the CCCTB is made mandatory

for all firms, even though they would also incur one-off costs for switching to the new

system. In terms of recurring costs, the burden for national administrations may go up

slightly if the CCCTB is not mandatory for all firms due to the required maintenance of

two parallel systems. In this case, they could still benefit from reduced case numbers due

to the one-stop shop approach by which multinational companies deal with the tax

administration of only one Member State.

5.2.3. Stakeholder views

Stakeholders were asked whether they support making the CCCTB obligatory for all EU

groups. Roughly one-third of the respondents are in favour and the same fraction is

against. Another 13% express a neutral stance while 15% opted for 'other'. Among

companies, slightly more than half of SMEs support a mandatory application for all EU

This is why in the 2011 impact assessment the 'optional for all' option was translated into the

assumption that all multinational entities would opt into the CCCTB.

kom (2016) 0685 - Ingen titel

groups, whereas only 20% of the large companies are in favour. The absolute number of

respondents representing respectively large companies and SMEs is relatively small

though and the results should be interpreted cautiously. Comments given along with the

replies suggest a wide range of nuances within each of the reply categories. Some

consider it more appropriate to apply cross-border or turnover criteria and/or to exclude

SMEs, and/or believe that a mandatory application should only be considered after an

initial optional phase. The range of views is particularly wide for the opponents. Some

prefer the CCCTB to be mandatory for all firms to ensure a level playing field. Some

suggest size thresholds or an opt-out possibility. Others are in principle against the

CCCTB.

5.2.4. Scope preferred option

Table 9 shows a summary of the performance of the two main scope definitions for the

CCCTB against the baseline. Column (1) summarises the impacts of a mandatory

application for all firms. Column (2) shows the impacts for the case of a limited

mandatory application. Evaluated on their merits in reaching the objectives, both scope

options improve the situation when compared to the baseline scenario. The option

'compulsory for all firms' is expected to perform slightly better in reducing tax planning

opportunities and has the advantage to eliminate all national corporate tax systems which

reduces costs for tax administrations in comparison to a limited mandatory application.

Otherwise, the two options are expected to be similarly effective in stimulating growth

and investment. However, the advantage of a full compulsory application in reducing tax

planning opportunities is small if compared to a mandatory scope definition that captures

the most relevant companies engaged in cross-border tax planning. At the same time, a

fully compulsory approach would also force companies into the CCCTB system that

have no tax planning opportunities and generally fewer benefits to reap from the

CCCTB. This is not a proportionate approach to achieve the objectives. Instead, granting

the possibility to apply the CCCTB to such companies, which are often active only

domestically and tend to be smaller, creates a more level playing field between them and

multinationals. Thus 'compulsory for all' is rejected.

It is proposed to make the CCCTB compulsory only for a subset of firms (option 2b),

based on their size. A size criterion proves to be a good proxy for capturing, in a non-

discriminatory manner, companies that are likely to engage in tax avoidance practices.

Defining the actual threshold implies a trade-off between the risk of not capturing tax

avoiders and the risk of targeting companies that do not ordinarily engage in cross-border

activities and would therefore not present a substantial tax avoidance risk. In addition,

this second category of companies should be expected to operate business structures that

would derive only little or no benefit from lessened compliance costs, given that they do

not operate cross-border. It seems at the very least appropriate to exclude SMEs from the

mandatory application as they are by and large not active internationally, hence unlikely

to engage in tax avoidance. The link between size and likelihood to engage in tax

planning being more robust for the very large firms, and taking into account the risk of

adverse threshold effects (disincentives to grow), would point to a rather high threshold.

Moreover, domestic firms do not seem as a whole to benefit from the CCCTB or from

staying out. To account for their different needs and to ensure a more level playing field,

it may be important to not oblige them to apply the system. This, too, points to a rather

high threshold, considering the shares of purely domestic groups captured by the various

thresholds displayed in Table 8.

kom (2016) 0685 - Ingen titel

Limiting the compulsory application to groups with a consolidated turnover above

EUR 750 million would serve the purpose of capturing the vast majority (ca. 64%) of

turnover generated by groups while limiting the risk of including purely domestic groups.

Furthermore, such a threshold would be coherent with the approach taken in other EU

initiatives to counter tax avoidance.

Importantly, the assessment should be contrasted with the proportionality of each option.

A 'compulsory for all' approach would put an unnecessary burden on some firms, in

particular small and micro corporations. Those companies would not necessarily be able

to benefit from reduced recurrent compliance costs and may no longer have access to

specific tax regimes. This is disproportionate to the extent that including those companies

would not much advance any of the two general objectives.

dimensions.

The choice for the mandatory scope does not change with respect to the preferred debt

bias and R&D options. In relation to the debt bias, this relies on the AGI being the

preferred option, as developed below.

The level of generosity of the R&D options has

no critical implications for the scope question either. The more generous and the larger

the set of firms that would opt in, the more limited the risk of not capturing all tax

avoiders. However, it is not obvious how to translate this effect into an exact amount for

the threshold.

Addressing the debt bias

This section examines how to address the debt bias in the CCCTB with the most

effective and efficient option vis-à-vis the objectives. The available options are:



'No further action', which is equivalent to maintaining the situation as foreseen in

the 2011 CCCTB proposal but aligned with the requirements by the Anti-Tax

Avoidance Directive (option 3a),

the non-deductibility of interest payments (option 3b),

the allowance for corporate equity (option 3c),

the allowance for growth and investment (option 3d), and

the allowance for corporate capital (option 3e).

The cost of capital allowance (option 3f) has been discarded in Section 4.3. In line with

the intervention logic, this section starts out with presenting the economic impacts, which

are more relevant for the options for the debt bias. The same sequence is applied in the

following section on R&D tax incentives.

5.3.1. Economic impacts

Impact on the financing decisions of firms

Current tax systems in the Member States usually provide a significant tax advantage to

debt (see also Section 2.2.1). They indeed favour debt-financed investments by allowing

a deduction of interest paid from the tax base, whereas there is no equivalent deduction

for the cost of equity.

For the analysis of the economic impacts of this differential treatment, it is necessary to

adopt an indicator that expresses the financing costs of a company for different sources

of financing. The indicator used here is the cost of capital (this concept is explained in

annex X). In most tax systems, the cost of capital is lower for debt-financed investment

due to the favourable tax treatment of debt. A profit-maximizing company will exploit

this difference and use more of the (cheaper) debt financing. Ideally, the cost of capital

for debt and equity should be equal. In this case the tax system would be neutral with

regard to financing decision (i.e. debt and equity face the same tax wedge).

ZEW (2016a) analyses the impact of various tax reforms to address the debt bias on the

cost of capital.

The reforms simulate revenue neutrality to avoid that the results are

driven by changes in revenue levels. Table 10 presents the results of the study.

Column

(1) shows the required cost of capital in the current tax systems assuming a real return on

a safe alternative investment of 5%.

Details on the concept and the underlying model are available in annexes IV and XII.

It should be noted that our model does not distinguish between the ACE and the AGI, which have here

the same macroeconomic effects.

Note: *Debt Bias: This is computed as the cost of capital for new equity minus the cost of capital for debt. Revenue

neutrality is achieved by adjusting the statutory CIT rate to achieve the same effective average tax rate. For

ACE, AGI and ACC, the defined interest rate assumed is 7.1%, corresponding to the long-term nominal

interest rate on a risk-free bond. The analysis is not qualitatively affected by the assumed rate (ZEW, 2016b).

The analysis shows that reform options to address the debt bias largely eliminate tax-

induced financing distortions by equalizing the cost of capital of debt-financed

investments and equity-financed investments.

Implementing the non-deductibility of interest increases the cost of capital for debt up to

the level for equity. Non-deductibility of interest leads to a broader tax base, which

allows reducing the CIT rate to achieve revenue neutrality. Due to this lower tax rate, the

cost of capital decreases slightly also for equity. Overall, the reform leads to an increase

in the mean cost of capital from 6.0 to 6.5%, despite the decrease in the CIT rate.

The allowance for corporate equity (ACE, option 3c), allowance for growth and

investment (AGI, option 3d) and the allowance for corporate capital (ACC, option 3e)

show identical results. They differ only with respect to their tax treatment of debt, with

the ACC providing a defined deduction whereas ACE and AGI generally allow for the

deductibility of actual interest paid.

This design difference does not matter here since

the assumed defined rate is identical to the nominal market interest rate.

All reforms

reduce the tax base and thus require an increase in the CIT rate to keep revenue

neutrality.

Despite the increase in the tax rate to guarantee revenue neutrality, the cost

of capital for equity decreases considerably.

Overall, the cost of capital decreases by

25%, from 6.0% to 4.5%. The reason for this result is that the cost of capital measures the

cost of an investment at the margin, i.e. the tax burden on the last euro invested. The

three reforms reduce this marginal burden thereby fostering investment. In contrast, the

tax burden on the economic rent, i.e. the profit above the normal market return is taxed

higher. From an economic point of view this type of taxation is efficiency enhancing

since it leads to fewer distortions in the investment decision of companies.

The model can simulate neither the effects of specific corrections done under the AGI nor its

incremental features. Hence it cannot differentiate between the ACE and the AGI.

Irrespective of the defined rate, the ACC always achieves financing neutrality. In contrast, full

financing neutrality for the ACE and the AGI is achieved only if the rate equals the market interest

rate.

Note, however, that for the ACC the impact on the base depends on the level of the defined rate

chosen. For sufficiently low rates, the tax base may be broader than in the status quo.

Due to the deductibility of interest the tax base for a 'marginal investment' (see annex XII) is small.

Therefore changes in tax rates have little impact and changes in the tax base dominate.

kom (2016) 0685 - Ingen titel

In the central scenario, the CCCTB (option 1b) is implemented without specific

provisions to address the debt bias but there would still be certain limitations on interest

deductibility (as following the implementation of the Anti-Tax Avoidance Directive,

interest deductibility limitations will be part of the CCCTB). Such limitation rules have

already been discussed in Council after the 2011 proposal. They would deny interest

deductibility partially either with respect to debt that leads to 'thin capitalisation'

(meaning an insufficient equity base relative to debt) or with respect to interest expenses

that exceed a certain percentage of gross earnings. These rules would overall imply a

strengthening of deductibility limitations currently applied in Member States.

They are,

however, not designed to achieve financing neutrality of the corporate tax system and

they tackle tax-induced indebtedness only partially.

Based on the results on the impact on cost of capital, all reform options are expected to

increase the share of equity in corporations. The introduction of an ACE in Belgium in

2006 and in Italy in 2011 offer the possibility to assess empirically their effect on

leverage.

For Belgium, a number of studies find a reduction in leverage of non-financial

Belgian firms after the introduction of the ACE.

Schepens (2015) finds similar effects

for the financial sector. For Italy, Panteghini et al. (2012) find evidence of a significant

decrease in the leverage of firms following the introduction of the ACE.

As no country has applied full non-deductibility of interest or an ACC, there is no

empirical evidence on their effects. Some research found that partial limitations of

interest via anti-abuse rules have somewhat decreased the leverage of companies.

Finally, simulations with CORTAX indicate that all options would indeed reduce the

leverage of firms, ranging from a decrease by 1.8% in the case of the ACE and AGI to

4.4% with the no interest deductibility (see Table 11).

Impacts on investment and growth

The macroeconomic impacts of the three potential reforms and the central scenario (in

which the CCCTB is implemented without a debt-bias reform) are summarized in Table

11. As before, the results have been obtained using CORTAX, which simulates all

reforms in an ex-ante revenue-neutral way by adjusting the CIT rate. The macroeconomic

effects of the ACE and the AGI are positive and superior to those of the no-action

scenario, the ACC and the non-deductibility of interest. The table shows the case of a

CCCTB applied to multinational entities only, but similar results are obtained under all

possible variations (CCTB or CCCTB, all firms or multinational entities only).

In all

these variations, the non-deductibility of interest leads to a negative effect on GDP,

driven by depressed investment.

As discussed in ZEW (2016b, chapter 6.1), 16 Member States apply interest deductibility limits to

intra-group debt only (of which 9 simply apply the arm's length principle without any specific rule),

whereas the other 12 Member States apply specific limitations to both intra-group and third-party debt.

The ACE in Belgium has some resemblance with the traditional ACE as it is based on stock of equity

and the anti-avoidance framework, although the way certain tax planning opportunities are addressed

is considered as incomplete by some (e.g. Zangari, 2014). In contrast, the Italian system is closer to the

AGI as it is based on incremental equity and has a relatively complete anti-avoidance framework.

See Princen (2012), aus dem Moore (2013), Panier et al. (2015) and Hebous and Ruf (2015).

See for example Büttner et al. (2012) and Blouin et al. (2014).

The results are confirmed even if one allows companies in the model to relocate their activities in

response to taxation (JRC, 2016).

kom (2016) 0685 - Ingen titel

The CORTAX model does not incorporate the incremental feature of the AGI, i.e. the

fact that it is only granted on equity increases. Sensitivity analyses presented in annex

XIII suggest that the extent of the economic impacts depends on the exact calibration of

the AGI (and the ACE), notably the choice of the rate.

The impact on investment has been assessed empirically for the Belgian ACE.

Aus dem

Moore (2014b) finds "highly significant and robust estimates that correspond to an

increase in investment activity by small and medium-sized firms of about 3 percent in

response to the ACE reform". Hebous and Ruf (2015) find no effect on production

investment from multinational affiliates, which are the focus of their study. Zangari

(2014) concludes that while the Belgian ACE has possibly benefitted investment by

SMEs, multinationals seem to have used the ACE mostly as a tax planning device. He

stresses the weaknesses of the anti-avoidance framework of the Belgian ACE as opposed

to Italy's system, where the same effect has not been reported. In addition, the fact that

the Belgian ACE at its introduction was granted on the already existing stock of a

company's equity implied a windfall gain for companies, without any impact on

investment decisions or their financing source.

Note: All simulations are changes compared to the baseline scenario of no CCCTB

The CORTAX simulations do now allow capturing the incremental feature of the AGI. However, sensitivity analysis on

the level of the allowance base suggest that the economic impacts of the AGI depend on its exact calibration.

Impacts on tax revenue

Revenue impacts are difficult to assess for non-deductibility of interest and the ACC

since none of the systems have so far been implemented. For the non-deductibility of

interest a back-of-the-envelope calculation, which does not take into account behavioural

responses, suggests an increase in CIT collected of between 0.4% and 1% of GDP (see

annex XII).

As neither a full non-deductibility of interest nor an ACC have been applied in practice, no empirical

study exists. In addition, the Italian and the Cypriot ACE are too recent to offer long enough time-

series data to investigate their impact on investment.

kom (2016) 0685 - Ingen titel

Regarding the revenue impact of the ACE, De Mooij (2012) finds a potential decrease in

the tax base by 14.1% and in tax collection by 0.49% of GDP. Zangari (2014) finds that

for the period 2009-2011, the revenue losses of the ACE represented about a third of CIT

collected. He estimates that the revenue cost would be lower by 15% taking into account

reductions in deductible interest as companies substitute debt for equity. The National

Bank of Belgium (2008) puts this correction at about a third of the gross revenue loss in

2006. More details on these analyses are available in annex XII.

The CORTAX simulations allow evaluating the additional revenue impact of debt bias

reforms compared to the CCCTB central scenario, i.e. the CCCTB without addressing

the debt bias. The figures are subject to a number of caveats. Notably it should be kept in

mind that CORTAX ensures budget-neutrality by adjusting the CIT rate and lump sum

transfers. In terms of total tax revenues the additional impact from 'non-deductibility of

interest payments' is positive in the order of EUR 13 billion (0.1% of GDP), due to a

larger increase in CIT revenues partly compensated by a decrease in other tax revenues.

The ACE/AGI reform is expected to decrease total tax revenue by EUR 19 billion (0.1%

of GDP), due to a larger decrease in CIT revenues partly compensated by an increase in

other tax revenues. With its design, the AGI is supposed to lead to lower revenue losses

than the ACE and could be made fully revenue-neutral by introducing offsetting tax rate

increases, without affecting the positive impact on financing neutrality. The ACC is

almost neutral with a negative impact of EUR 1 billion, due to a decrease in CIT

revenues largely offset by an increase in other taxes.

Impact on administrative burden

None of the options seem to imply important changes in administrative burden. They

concern only one aspect of the computation of the tax base and are not per se more

burdensome than e.g. the application of depreciation rules. The non-deductibility of

interest is straightforward as is the application of a defined interest rate to equity.

The application of anti-avoidance rules may generate additional compliance and

administrative costs for companies and tax administrations respectively. This is

specifically the case for the AGI but, depending on their depth, also for the ACE and the

ACC. These costs of course need to be balanced with the objectives of fairness.

Compared to the no-action scenario and the non-deductibility of interest, the application

of AGI, ACE and ACC could then lead to increased administrative burden.

5.3.2. Fairness impacts

The design of individual debt-bias reforms is crucial for the impacts on fairness. Not

addressing the debt bias would leave opportunities for groups operating cross-border to

shift profit via the debt instrument, at least under a common base.

Fully disallowing interest deductibility would suppress such opportunities and would

therefore address the fairness aspects. The ACC would reduce tax planning opportunities

via transfer price manipulations on interest rates as the deductible interest would not be

based on the actual rate but on a defined one.

kom (2016) 0685 - Ingen titel

The ACE has been criticised because of the tax planning opportunities

it can

theoretically open in the form of cascading of the deductions on the same initial capital.

Under the current system, interest paid is taxed at the level of the receiver, which is

justified by the fact that the payment is tax deductible at the level of the payer. At the

level of company groups, the reverse is true for dividends. Dividends paid are not taxed

at the level of the receiver (via participation exemption in the EU), which finds its

justification by the fact that they are not deductible at the level of the payer. The ACE

changes this system by allowing a notional deduction for equity at the level of the payer

(but does not change the exemption for dividends at the level of the receiver). This opens

the following possibility to cascade the benefits of deductions: a parent borrows debt (D)

from a bank and/or receives equity injections (E

) from shareholders and re-injects the

full amount of capital into a subsidiary as equity (E

= D+E

). Under an ACE system

without proper anti-avoidance rules, the parent company receives tax deductions in the

form of ACE and deductible interest on its equity Ep and its debt D, respectively. The

subsidiary receives a tax deduction in the form of an ACE on the same (transferred)

capital.

To avoid such cascading, there is a need to make sure that the same euro of capital

invested in the group receives tax deductibility only once.

This is achieved with an

allowance for growth and investment (AGI). The embedded anti-avoidance measures

ensure that the funds injected in a group benefit only once from a deductibility (via

deductible actual interest or the allowance on equity). The system would remove the

loopholes used for aggressive tax planning.

These specific rules to make the system robust to tax planning can include inter alia a

stricter definition of the ACE/AGI base to exclude items that do not represent business

needs or genuine investment, as well as participations and own shares, the limitation of

the benefits of the ACE/AGI both in time (via an incremental system with a moving

reference date) and amount (with a fixed limit), general anti-abuse rules (GAAR) and

specific anti-abuse rules in terms of interest limitation rule; last but not least the AGI

For the Belgian ACE, Hebous and Ruf (2015) find indications for the use of such tax planning

strategies.

Zangari (2014) discusses the Belgian and Italian ACE systems and the role of anti-avoidance

provisions targeting intra-group transactions.

kom (2016) 0685 - Ingen titel

offers a correction mechanism at the level of either the parent or the subsidiary to avoid

the cascading of the benefits.

5.3.3. Stakeholder views

In the stakeholders' consultation (see annex II), an overwhelming majority of respondents

have voiced that the debt bias shall be addressed in the proposal. Among companies who

responded more than 60% are in favour of addressing the debt bias, large companies and

SMEs alike.

Most of the NGOs opt for the non-deductibility of interest method whereas from the

companies' perspective there is resounding support for the ACE/AGI

. Like the

companies, a strong majority of business/professional associations and consultancy/law

firms expressed their preference for the ACE/AGI. A few respondents were in favour of

the ACC/CoCA. Some respondents indicated that anti-avoidance measures are an

important component of a possible ACE/AGI.

Several respondents mention the interest limitation rules foreseen in BEPS action 4 to

indicate that interest limitation shall probably not go beyond those. Finally, many

respondents emphasise the need for a solution to promote investment.

5.3.4. Debt bias preferred option.

In light of the above, deductibility for equity costs in the form of an allowance for growth

and investment (AGI, option 3d) is the option that scores best in terms of economic

outcomes while at the same time addressing the fairness aspects of the tax system.

Indeed, looking back at the objectives, both the non-deductibility of interest and the AGI

would reduce tax planning opportunities, something the ACE would not do. When it

comes to levelling the playing field for domestic and multinational companies, we have

seen that the debt bias is particularly detrimental for SMEs, which constitute a large share

of domestic companies. By entirely removing the debt bias, all options have the potential

to help SMEs. However, the ACE and the ACC offer planning opportunities that would

favour multinational entities over domestic companies.

The ACE, AGI and ACC may bring some complexity notably when it comes to their

details. This is certainly true when compared to the non-deductibility of interest which is

a simple, albeit radical, solution. However, a specific issue arises with the application of

the full non-deductibility of interest in the financial sector. Applying the full non-

deductibility of interest paid to the financial sector would represent a disproportionate

financial cost for the sector, unless by symmetry the interest received would be

exempted. This however would in turn mean that the larger part of traditional banking

would be exempted from corporate taxation. Another practical question concerns the

compatibility of non-deductibility of interest within the international landscape. In most

countries interest is taxed based on residence whereas disallowing interest deductibility

would imply moving to taxation at source.

The AGI was not formally part of the public consultation as it is a special case of the ACE.

kom (2016) 0685 - Ingen titel

In the panel of options, only the AGI – by ensuring that deductibility is granted only once

– offers a remedy without leading to double taxation. The non-deductibility of interest

creates double taxation unless interest received is exempted at the level of the recipient.

In theory, all options should offer a satisfactory remedy to the distortions in the financing

decisions. However, the same is not true when it comes to investment decisions and the

attractiveness of the EU as the non-deductibility of interest would have adverse effects

and the ACE would distort choices because of potential tax planning opportunities.

Taking no action, i.e. introducing the CCCTB without a debt bias solution, would imply

that problems due to distorted financing incentives remain unaddressed, whereas profit

shifting via debt would be mitigated to a certain degree through limitation rules in the

CCCTB on interest deductibility.

In conclusion, the AGI addresses the debt bias and is expected to have a positive impact

on the investment, even if implemented in a revenue-neutral way. The robust anti-

avoidance framework inherent to the AGI makes it the preferred debt bias option.

Table 12 summarises the impacts of the different debt bias options and assesses them

against the central scenario for a CCCTB. This means that options are compared to a

situation with a CCCTB which does not address the debt bias. The table therefore

answers the questions whether a debt bias solution will improve the CCCTB vis-à-vis the

central scenario. The analysis shows that granting no interest deductibility at all is

attractive to reduce tax planning opportunities. At the same time this option clearly

hampers investment due to its impact on capital costs. An allowance for equity features

high on improving the economic environment, but scores lower when tax planning

considerations are taken into account. The allowance for growth and investment (AGI)

comes with stricter anti-avoidance rules and is only granted on incremental changes in

the capital stock. It provides economic benefits while reducing the risks of tax planning.

The allowance for the cost of capital (ACC) is similar to an ACE, but less favourable in

economic terms.

5.3.5. Independence of the debt bias preferred option with other option

dimensions

The conclusion on the preferred debt bias option does not depend on the preferred option

for the scope or the R&D incentive. The results from the CORTAX and ZEW studies

confirm that the ranking of debt bias options is stable, irrespective of the scope (and

indeed independent also from consolidation). The specific design of the R&D incentive

should not have implications for the choice on scope or debt bias either. The debt bias is

a wider issue, changing the cost of capital for all investments, not only R&D

investments.

5.4.

Treatment of R&D expenses

This section reviews the two retained options for ensuring that the CCCTB provides

sufficient incentives to invest in R&D. The available options are 'No further action' on

R&D (option 4a), which is equivalent to immediate expensing of R&D in the 2011

CCCTB proposal, and granting a super allowance for R&D expenses (option 4b). The

options of granting tax credits or granting tax incentives for income from intellectual

property (option 4c) have been discarded in Section 4.4.

kom (2016) 0685 - Ingen titel

5.4.1. Economic impacts

Option 4a provides full and immediate deductibility for R&D expenses.

The majority

of national tax incentives provide currently larger than full immediate expensing

(additional allowances amount to up to 200% in Latvia and Lithuania) or a tax credit for

qualifying R&D costs.

Annex XI provides an overview table of the systems currently

applied in Member States and selected third countries.

A systematic comparison of the generosity levels requires a measure which condenses

different features of the tax system (rate, design of the incentive, etc.) into one indicator.

Such an indicator of tax support to R&D is the '1-B-index' (see box 3). This index takes

the value zero if the tax system does not provide any tax incentive on business R&D

expenses beyond immediate expensing of all R&D expenses. It takes a positive value if

the incentive is larger. It takes a negative value if the incentive is smaller.

Box. 3 The B-index and the 1-B-index

The B-index measures the minimum level of profit before tax that a representative company needs to

earn to break even on one euro spent on R&D. The B-index summarises a large array of qualitative and

quantitative information about R&D tax incentives and depreciation regimes for R&D assets as

collected by the OECD. An alternative and more intuitive way is to look at the one minus B-index.

1-B-index = Tax subsidy (if positive) or tax burden (if negative).

The 1-B-index shows the influence of R&D tax incentives on the price of business R&D (user cost). For

example, a value of 0.1 suggests that the price for a business to invest in R&D is 10% lower than it

would have been in the absence of taxation, whereas a value of -.05 suggests that the user cost is 5%

higher than it would have been in the absence of taxation. A value of 0 corresponds to the case of no

taxation.

Source: OECD and Warda (2001).

Table 13

shows the computations of the 1-B index for all EU countries. The values are

positive in 21 Member States, i.e. these Member States provide more tax support beyond full

immediate expensing. They are negative in four Member States and the value is zero for

three Member States. The weighted average of the tax subsidy rate for the EU stands at 0.12.

This means that for every euro invested in business R&D in the EU, Member States give on

average a subsidy of 12 cents.

Option 4a offers immediate expensing for all R&D costs except for the estimated 5% related

to buildings and land. This would translate into a tax burden on R&D of -0.01 and not

maintain the current generosity level of the tax treatment of R&D expenses.

As explained in Section 3.6.1., the exception is expenses for R&D buildings which cannot be

immediately expensed, but these account for only 5% of total R&D expenditure.

These considerations may be affected in case a country requires capitalisation of some current R&D

costs. The effect of expensing or capitalisation of current R&D costs was considered in preparation for

the 2011 proposal and the results of the simulation reveal no considerable impact (ZEW, 2008).

Impact on R&D investment

The vast majority of empirical research concludes that expense-based R&D tax

incentives lead to additional R&D investment.

The estimates of the size of this effect

are widely diverging, partly due to differences in methodologies and countries covered

by the studies. Recent studies conclude that the tax elasticity (the proportional change in

R&D spending due to a 1% decrease in the tax burden) is positive and close to, but less

than one.

To reflect these results in a plausible but conservative manner, an elasticity of 0.8 is

assumed in the calculations presented in table 14.

An elasticity of 0.8 means that a 10%

reduction in the price of business R&D results in an 8% increase in business R&D. In

line with the result above that Option 4a would lead to a deterioration in incentives, the

analysis finds an 18% reduction in R&D spending compared to the baseline (existing

national schemes). An additional allowance (option 4b) of 33% is required to achieve the

same level of tax subsidy as in current national tax schemes.

See the study by CPB (2014) for a recent survey of the literature.

See for example CPB (2014), Becker (2015) and Koehler et al. (2012). The effects, may, however be

underestimated, as some research suggests that R&D tax incentives may assessed to be less effective

than they really are if studies do not take into account the endogenous determination of tax policies,

i.e. the fact that tax reforms are often introduced to offset economic downturns (Chang, 2014).

Alternative calculations were also performed using a plausible range of literature-backed elasticities

(from 0.5 to 1.2). Minimum and maximum bounds suggested by these alternative elasticities are also

presented.

Note: R&D buildings are depreciated under all options. Inclusion of own-calculated B-indices leads to a lower

average tax subsidy in the EU than the one calculated based on the available OECD indices as the GDP-

weighted average B-index drops from 0.88 to 0.86. Under the B-index of 0.86, the full expensing has worse

consequences on R&D, as the drop in R&D is -23% (from -18% with the full set of 28 B-indexes). An

allowance of 37% is needed to achieve pre-reform levels (up from 33%).

An additional allowance of 100% (on top of full expensing) would significantly improve

existing incentives to engage in R&D, with an expected increase of about 17% in

business R&D investment compared to the status quo. Meeting the Europe 2020 target of

3% of GDP devoted to R&D would require an even bolder allowance. If 2% of GDP

were to come from the private sector, business R&D investment would need to increase

by 54% from current levels.

An additional allowance of 200% could result in an

increase in business R&D by 52%, approximately meeting the Europe 2020 target.

However, the effectiveness of an additional allowance of a given level will vary with the

applicable CIT rate. The higher the tax rate the larger the benefit for the company

investing in R&D and thus the stronger the incentive to invest. Under the CCCTB the

relevant rate would depend on a weighted average of tax rates after formula

apportionment. To the extent that Member States change CIT rates after introduction of

the CCCTB this could change the generosity level of the allowance.

Impact on tax revenue

In terms of foregone tax revenues, granting an additional allowance of 33% should have

an overall neutral impact on CIT revenues as it corresponds to the R&D tax incentives

already offered in EU Member States.

Estimates of the likely changes in CIT revenues

under the two options for different rates of the allowance, as presented in annex XII, vary

from 5% for an additional allowance of 100% to 15% for an allowance of 200%. These

estimates are broadly in line with OECD (2015c).

Neither of these estimates takes into account revenue gains from the reversal of all patent

boxes currently applied in the EU. Griffith et al. (2014) simulate the revenue impacts of

introducing patent boxes in four countries. They find that tax revenues from new patents

are less than half of their pre-reform levels in the four countries concerned. The impact

from the removal of patent box regimes would be the same for both options.

R&D business expenses stood at 1.3% of GDP in 2014 and thus the shortfall in the EU amounts to

0.7% of GDP (Eurostat data).

The effect will depend on the tax rates Member States choose after the introduction of a CCCTB.

Impact on different types of companies and possible targeting of R&D incentives

A conclusion from the economic literature is that tax incentives should not be linked to

the size of a company but rather to the desirable outcome such as more research and

innovation investment.

100

The effects of R&D tax incentives vary across firm types, notably size. In general, there

is no undisputed conclusion whether SMEs respond more strongly to R&D tax incentives

than large companies. Recent evidence however suggests that knowledge spillovers from

large firms exceed those from small firms (Bloom et al, 2013). Targeting R&D tax

incentives to firm size needs to consider both, the degree of responsiveness and the level

of spillovers. There is nevertheless evidence that size may not be the best selection

criterion as the impact of tax incentives on R&D spending for start-up firms can exceed

the average impact. Therefore, targeting young companies can be considered a better

practice than targeting SMEs.

101

If the CCCTB is more generous than national tax incentives schemes, it could be seen as

favouring incumbent firms. This is because more generous R&D tax incentives can be

associated with a more concentrated growth distribution in R&D intensive sectors, which

may favour incumbent firms (Bravo-Biosca et al., 2013). Young companies can

challenge incumbent businesses and generate proportionally more jobs (Criscuolo et al.,

2014). The EU has currently fewer young leading innovative companies than the US in

fast moving sectors (Cincera and Veugelers, 2013). Tax incentives can hence be designed

to support young companies directly with relatively more generous provisions (as

currently applied in France, Belgium, the Netherlands and Portugal), by including

options to carry forward the R&D expenditure (as in most national schemes) and/or to

get a cash refund (as in seven EU countries). Such features offer young firms more

flexibility and reduce the uncertainty associated with investment decisions.

Impact on EU competitiveness

Based on the conclusion that option 4a weakens current incentives for businesses to

invest in R&D and given that the EU underinvests in private R&D compared to other

innovation leaders such as US, Japan and South Korea (which all apply R&D tax

incentives), option 4a could further deteriorate the competitive position of EU businesses

and could also lead to delocalisation of R&D efforts of EU businesses from the EU to

other countries.

The likely impact of the tax treatment of R&D expenses on GDP growth is difficult to

estimate. The IMF (2016) expects a long-term increase in GDP of about 5% following an

increase in business R&D by 38% based on the literature estimates of the elasticity of

100

101

This seems to be the focus as well in national tax systems. A 2015 study on SME taxation concludes

that SME tax incentives are not as frequently implemented as R&D tax incentives. Mostly, reduced tax

rates are employed to support SMEs on which available evidence suggests that such SME reduced

rates may prevent companies from growing (IMF, 2016). Most SME tax incentives seem to benefit

only micro and small enterprises, while medium-sized corporations basically benefit only from R&D

tax incentives (see also table 37 in annex XI). Reductions in the effective tax burden due to R&D tax

incentives for large corporations comes mostly from reductions applicable to the tax base, i.e.

enhanced allowances (VVA and ZEW, 2015).

See the discussion and evidence provided in CPB (2014), OECD (2016) and IMF (2016).

kom (2016) 0685 - Ingen titel

output with respect to changes in business R&D. Extrapolating from this, an allowance

of 100% and 200% may increase GDP by roughly 2% and 7%, respectively. However,

linear extrapolations should be treated with caution.

102

Impact on administrative burden

As explained above, introducing the CCCTB is expected to reduce administrative burden

in relation to R&D tax incentives, which currently vary considerably across the EU

(annex XI). This reduction in administrative burden is expected to be the same for

options 4a and 4b.

5.4.2. Fairness impacts

Stimulating R&D activities should also contribute to the objective of enhancing fairness.

13 EU countries currently offer tax reductions on the income earned from exploiting

intellectual property. Such patent boxes have been introduced in recent years with the

declared objective of boosting R&D, high-tech jobs and competitiveness. However,

patent boxes have been criticized from the outset. Research shows that they do not

stimulate R&D and may rather be used as a profit-shifting instrument, leading to high

revenue losses. Section 4.4 discusses this more and Table 1 in Section 2.1 illustrates the

large tax saving potential by exploiting patent boxes. Patent boxes reward successful

innovations which already profit from an intellectual property protection. They could

thus make research efforts that are not patentable, with potentially higher social

spillovers, less attractive. Furthermore, the use of intellectual rights is sector specific.

103

Overall, both options 4a and 4b would increase fairness by reducing IP-related profit

shifting and improving the level playing field between those research efforts which

benefit from IP-protection and those which do not.

5.4.3. Stakeholder views

A majority of respondents (55%) are in favour of making the CCCTB more favourable

for R&D than in the 2011 CCCTB proposal, while 18% are against. Those in favour are

companies – in fact all large companies and 80% of SMEs who responded - while most

of the NGOs and private individuals are against a more favourable regime.

Around half of the respondents who are against making the framework more favourable

refer to concerns about harmful tax competition induced by tax schemes based on income

from intellectual property. Many respondents highlight that any scheme under the

CCCTB should be based on actual R&D costs. Other responses in this group suggest a

preference for other means to stimulate R&D.

102

103

The variance observed in quantitative literature on the returns to R&D (e.g. Hall et al., 1999) argues

against crude linear extrapolations. In fact literature on the statistical distribution of highly valuable

inventions (e.g. Scherer and Harhoff, 2000; Silverberg and Verspagen, 2007) suggests that they have

no mean and no variance and therefore attempts to forecast the aggregate outcome of R&D with

precision need to be treated with caution.

Hall et al. (2013) find that in the UK even among firms that conduct R&D, only 4% patent. Findings

are similar for the US as 5.5% of US manufacturing firms own a patent (Balasubramanian and

Sivadasan, 2011). Sectors such as computers, electronics, machinery, chemical and pharmaceuticals

seem to have the highest patenting activities (Squicciarini and Dernis 2013). The empirical evidence

suggests that for many sectors patents seem an ineffective way to appropriate returns and secrecy and

lead times are used extensively (Arundel, 2001; Hanel, 2008; Hall et al., 2014).

kom (2016) 0685 - Ingen titel

The suggestions of respondents who are in favour of making the framework more

favourable mostly concentrate on super deductions.

Across the various groups of respondents, some believe that Member States should be

allowed to retain their flexibility in granting R&D tax credits or super deductions in

parallel to the CCCTB.

5.4.4.

Preferred R&D option

Given its impact on R&D investment and positive spillovers for the whole society, option

4b, i.e. granting an additional allowance, is preferable to maintaining the 2011 CCCTB

proposal on R&D (option 4a). An additional allowance between 33% and 100% would

be preferable to maintain or further encourage R&D investment in the EU at a reasonable

cost. To stimulate growth of innovative firms and ensure fairness, a more generous

provision could be proposed to young innovative companies that would opt into the

CCCTB. An alignment of definitions and eligible costs with EU state aid rules would

ensure coherence with other EU policies.

Table 15 summarizes the impacts of the two options. Column (1) shows the central

scenario for the CCCTB which by definition is neutral (option 4a). Column (2) shows the

impacts in comparison to this central scenario of an additional allowance (4b).

5.4.5. Independence of the R&D preferred option with other option

dimensions

The preferred choice for the treatment of R&D expenses does not have important

dependencies with the preferred option for the scope or the debt bias. This is due to the

possibility to opt in and the objective to include R&D tax incentives that are at least as

kom (2016) 0685 - Ingen titel

generous as what Member States currently apply. However, it is possible that in some

cases a company will have more incentives to invest in R&D under the national system,

but falls under the mandatory scope. This would be an argument for keeping the

threshold for the mandatory application rather high to reduce the possibility for such

cases. The considerations between the principal choices for the R&D incentive

(additional allowance, tax credit etc.) do not depend on the preferred debt bias option

either. As shown above, in order to design the preferred R&D option in a way to

maintain at least current generosity levels, at least immediate expensing of all R&D costs

needs to be ensured. As this means that R&D costs are not capitalised, there is no

interaction between the generosity of the R&D incentive and the choice for the preferred

debt bias option, which is the AGI.

5.5.

The staged approach

This section presents (i) the impacts expected, relative to the CCCTB, from an initial

stage without consolidation and formula apportionment (option 5a); and (ii) it assesses

whether it would be opportune to foresee some form of cross-border loss offset during

this initial stage (option 5b).

It is clear from this impact assessment and the one underpinning the 2011 proposal that

the preferred option is the CCCTB. However, discussions in the Council have shown that

the CCCTB is unlikely to be adopted in one piece, consolidation being the most difficult

and controversial element. It no longer appears promising to move forward with the

CCCTB in one single go and the Commission therefore decided to pursue a pragmatic

approach, postponing the work on consolidation until after the common base has been

agreed and implemented. Therefore this section presents the economic and fairness

impacts of the initial stage, in which the common base is implemented. This means that

provisions on profit and loss consolidation within groups and formula apportionment

across Member States would be postponed. All other features of the base definition,

notably an allowance for growth and investment (AGI) and R&D incentives would be the

same in the common base and the CCCTB.

The comparison of options in this subsection concerns merely the possible inclusion of

some form of cross-border loss offset, if the political environment required the staged

approach for the introduction of the CCCTB. The main difference between cross-border

loss offset and consolidation is that the latter would fully offset losses and profits within

a CCCTB group whereas cross-border loss offset would only allow a vertical offset

between parents and subsidiaries. In addition, the cross-border loss offset envisaged

would foresee a reincorporation of the loss offset after some time.

5.5.1. Economic impacts

Table 16 presents the results from the CORTAX simulations for the common base with

and without cross-border loss offset as well as, for comparison, the results for the

CCCTB. All the simulations presented assume that all multinational enterprises apply the

common base and that the common base includes the ACE/AGI to address the debt

bias.

104

It is clear that the CCCTB is expected to achieve better economic results than the

common base. GDP, investment, wages and employment all perform better. In the model,

104

R&D incentives should also apply but these do currently not feature in the CORTAX model.

kom (2016) 0685 - Ingen titel

three main effects drive these differences in the impacts. First, under the CCCTB

compliance costs are assumed to fall to zero for subsidiaries of multinational enterprises,

whereas they stay the same as before under the common base.

105

Second, consolidation

allows for the immediate offset of losses against profits made somewhere else in a

multinational group. This lowers the tax burden and the cost of labour and the cost of

capital. Third, the move to formula apportionment removes an important distortion to the

location of real factors and replaces it by another, yet less significant, distortion induced

by formula apportionment (see discussion Section 5.1). Overall, since in the CORTAX

model the key economic benefits of the reform are driven by the ACE/AGI reform, the

relative differences between the common base and the CCCTB are relatively minor.

Turning to the cross-border loss offset, CORTAX results indicate a fairly modest positive

economic impact of allowing cross-border loss relief, where parents can claim losses of

their subsidiaries. The most important benefit from offering some cross-border loss relief

is the enhancement of cash-flow capacity of businesses (for instance, by compensating

start-up losses in a Member State with profits in another Member State) and the resulting

support for cross-border investment within the EU.

Currently only a few Member States offer limited forms of cross-border loss

compensation. Some cross-border loss offset would alleviate in most Member States

differences in the treatment of groups operating cross-border and domestic groups.

Moreover, limited or non-existing cross-border loss offset implies differences in tax

treatment of foreign permanent establishments and foreign subsidiaries. As the 2011

impact assessment notes, other potential benefits include the reduced risk of investment,

as losses are better insured, and increased efficiency in the international allocation of

productive capital.

Impact on administrative burden

The administrative burden would be reduced by much more under the CCCTB compared

to the common base. Consolidation brings major benefits in terms of reduced compliance

105

A sensitivity analysis, in which the compliance costs instead are reduced by 50% is also performed in

the CORTAX study.

kom (2016) 0685 - Ingen titel

costs, eliminating the necessity to comply with the arm's length principle. For groups, the

absence of consolidation implies that cross-border transactions between group members

and associated enterprises would continue to be subject to transfer pricing rules and filing

formalities. It would therefore be necessary to work out arm's length adjustments. In

addition, groups of companies would have to continue dealing with as many tax

administrations as the number of Member States where they have a taxable presence (i.e.

subsidiary or permanent establishment). On the other hand, formula apportionment

requires documenting additional information on the factors used in each company entity

in order to apply the formula.

106

Thus the CCCTB is expected to be particularly effective in reducing recurrent tax

compliance cost. In terms of one-off costs for setting up a subsidiary in a new location,

the common base would already constitute a major improvement as a company

expanding cross-border would not have to deal with a new tax system. Tax

administrations would be able to benefit from a reduced number of cases and fewer

dealings with transfer pricing issues only once the CCCTB is implemented.

5.5.2. Fairness impacts

Consolidation and apportionment is clearly an important element to reap all the benefits

from reducing tax avoidance. Whereas the common base would address profit shifting by

exploiting patent boxes and mismatches in the tax systems, the CCCTB would in

addition render profit shifting via transfer pricing and debt shifting unattractive

(assuming that both the common base and the CCCTB would be mandatory for the most

relevant companies).

A mechanism for a cross-border loss relief outside formula apportionment may give rise

to new opportunities of tax planning and profit shifting in favour of multinational

companies. Anti-tax avoidance provisions that may be implemented in order to prevent

an abusive use of cross-border loss relief could have only limited dissuasive effect. It

should also be underlined that tax administrations would have a crucial role in order to

prevent abuses. Hence, anti-avoidance provisions could remain ineffective to the extent

that tax administrations are not capable to apply them.

The loss relief should therefore have a narrow scope to minimise possibilities for tax

avoidance. Notably, to safeguard national tax revenues, the deducted losses should be

reincorporated ('recaptured') automatically if this has not occurred after a certain number

of years or if the requisites to qualify as an immediate subsidiary or permanent

establishment are no longer met. In addition, it should be ensured that companies cannot

artificially reduce their tax bill by buying loss-making companies. This is an issue that

has already been recognised in national systems that provide a loss relief for groups and

can be addressed via specific anti-avoidance rules.

5.5.3. Stakeholder views

More than 50% of companies who responded are in favour of a temporary cross-border

loss relief. The positive view is shared by large companies and SMEs alike. The majority

of the companies argue that the current lack of mechanisms available to offset cross-

The required information concerns sales by destination, tangible fixed assets, employees and the wage

bill.

kom (2016) 0685 - Ingen titel

border losses is one of the major obstacles to the completion of the single market and

reduces the competitiveness of the EU. A few respondents suggest that the cross-border

loss offset should be extended to non-EU companies and permanent establishments,

given that competitiveness of EU companies needs to be regarded on a global scale.

A strong majority of respondents from business/professional associations and

consultancy/law firms believe that consolidation is essential. However, they would

accept a transitory and temporary cross-border loss relief as a second-best approach.

Some envisage resistance from Member States in offering wide-ranging cross-border

relief as taxes should be paid where value is created. Others advocate the introduction of

an EU wide regime, not linked to the CCCTB, to be implemented into domestic

legislation.

Conversely, most NGOs and civil society organizations do not support a temporary

mechanism for cross-border loss relief. They fear it would only shrink the taxable base of

multinational companies and open up the system to new types of aggressive tax planning

while postponing consolidation would remove the main benefit of the proposal.

5.5.4. Conclusion on staged approach

Should an initial stage without consolidation be required politically, a limited form of

cross-border loss offset (option 5b) could have small positive impacts on key economic

variables such as GDP, the labour market and investment.

5.6.

Impact on SMEs

SMEs would be effectively excluded from the mandatory application of the CCCTB

through the recommended high turnover threshold. Given the low degree of

internationalisation of SMEs, the risk of imposing an additional administrative burden

(through a change in the tax rules to which they would be subjected) would not

necessarily be offset by the benefits of having a common base throughout the EU.

However, the CCCTB is expected to support growth and investment and to reduce

compliance costs when expanding across border. SMEs might therefore want to opt into

the system, which would allow them to benefit from the CCCTB, including the AGI and

the allowance for R&D expenses.

Indeed 63% of SMEs that responded to the public consultation are in favour of providing

the possibility to opt into the CCCTB. Views by SMEs on other issues have been

summarised above in the respective sections on the public consultation.

The impact of debt bias measures is likely to be higher for SMEs that would opt for the

CCCTB. The debt bias is particularly detrimental for young and innovative firms, whose

access to external funding is more difficult. Among the options, the AGI could

potentially be particularly favourable to growing companies, which are likely to be small

on average. Caiumi (2015) investigates the impact of the Italian ACE on the debt bias

and finds that the corrective effect is particularly strong for SMEs.

5.7.

Social and environmental impacts

There are no relevant environmental impacts expected from any of the options. Social

impacts will also be limited, but two aspects are worth mentioning. To the extent that

kom (2016) 0685 - Ingen titel

positive indirect impacts on the labour market materialise (employment and wages),

positive social impacts are also expected. This aspect lends further support for a CCCTB

with an AGI, which has the most positive impacts on the labour market.

In addition, the significant reduction of corporate tax avoidance under the CCCTB is

expected to influence positively general taxpayer morale. The positive impact on

taxpayer morale is maximized with a CCCTB and a mandatory scope that ensures that

the major share of corporate tax avoidance is no longer feasible.

In the longer term, the provision of R&D tax incentives in the CCCTB which would lead

to more investment in R&D could improve the living standard by generating positive

social spillovers. Cost-benefit analyses of the social effects of R&D tax incentives carried

out in the Netherlands, Canada and Japan find positive effect on welfare.

107

5.8.

Conclusion on the preferred option

5.8.1. Design components of the preferred option

The analysis of impacts in the previous sections focusses on three design elements of the

CCCTB proposal. These elements were added to the 2011 proposal to address the new

general and specific objectives outlined in Section 3. The general objectives are to (1)

enhance the fairness of the tax system and to (2) stimulate growth and investment.

Section 5.1 shows that the CCCTB offers clear advantages in comparison with the

baseline scenario. The anticipated effects of enhancing fairness via reduced corporate tax

avoidance, ensuring a fair tax contribution from the corporate sector, a more level

playing field among companies and the expected positive impacts on taxpayer morale are

critical, even if not all of them are quantifiable. Small positive economic and investment

effects arise, notably by removing obstacles in the single market. Overall, welfare is

expected to increase slightly. The impact on public finances will largely depend on how

Member States will adjust tax rates, but also on some calibration issues such as the rate

for the AGI. Under the assumption of partly offsetting changes in CIT rates, the

simulations show a small decrease in total tax revenues by 0.2% of GDP, due to a

reduction in CIT revenues partly offset by an increase in other taxes as a result of the

increased economic activity. However, these figures do not capture expected positive

impacts from closing important tax planning channels.

Effectively reducing tax avoidance by multinational entities and increasing fairness

through a more level playing field in the EU can only be reached if the relevant

companies have to operate under a CCCTB. Section 5.2 concludes that a scope which is

mandatory for a defined set of multinational entities and optional for other companies is

the preferred option. The limit of compulsory application is set to groups with a high

consolidated turnover. A threshold of EUR 750 million would serve the purpose of

capturing the vast majority (ca. 64%) of turnover generated by groups while limiting the

risk of including purely domestic groups. Furthermore, such a threshold would be

coherent with the approach taken in current EU initiatives to enhance tax transparency.

107

Parsons and Phillips (2007) conclude that the tax incentive in Canada had a positive welfare effect of

eleven cents for every dollar spent in terms of lost tax revenue. Lokshin and Mohnen (2009) conclude

that the Dutch program resulted in a 16% net welfare gain. Such analyses are sensitive to the

assumptions made, for example on spillover rate and administrative and compliance costs.

kom (2016) 0685 - Ingen titel

Solutions for the CCCTB to address the debt bias in corporate taxation are analysed in

Section 5.3. The options to address the debt bias are assessed not only based on their

economic merits of removing the distortion, but also with a view to minimising the risks

of tax planning. The allowance for growth and investment (AGI) is identified as the

option that best matches both criteria. Compared to the CCCTB without AGI, the results

also show much larger positive impacts in terms of overall investment which increases

by up to 3.4% depending on the level of allowance.

Section 5.4 analyses the question of the appropriate level for an allowance for R&D

investments. When setting the level of the allowance, policy makers have to weigh the

increase in R&D expenses from granting the allowance with the loss of tax revenue. The

simulations show that an additional allowance between 33% and 100% (i.e. beyond full

immediate expensing) would be preferable to maintain or further encourage R&D

investment in the EU at a reasonable cost. Allowances will reduce the tax bases and

therefore revenues. However, costly and inefficient existing patent box regimes in

Member States would be removed with the CCCTB. This could partly offset some of the

revenue losses.

In conclusion, a mandatory CCCTB for very large companies, an AGI with well-

designed anti-avoidance measures and an R&D tax incentive designed as a super

allowance for R&D expenses define the preferred option for the re-launch of the

CCCTB.

5.8.2. Regulatory fitness and simplification of the preferred option

Tax compliance costs are an important burden for businesses and their reduction will be a

major advantage of the implementation of the CCCTB. Estimated compliance costs for

large companies amount to about 2% of taxes paid, while for SMEs the estimate was

about 30% of taxes paid. Compliance costs are estimated to increase with cross-border

activity and with increasing number of subsidiaries. Tax reform data show that numerous

CIT reforms took place after the crisis and many measures were directed at reinforcing

the international anti-abuse framework. In the light of this, the reduction of compliance

costs when setting up an additional subsidiary when the CCCTB is introduced remains a

major advantage: The compliance costs for companies will decline for those cases where

cross-border investments are involved – partly because of the abolition of transfer pricing

documentation, more generally because there is only one set of rules to comply with.

Given the fact that the CCCTB is more streamlined than national systems, one could

expect that also domestic compliance costs are reduced. In any case, the choice to enter

the CCCTB will reflect compliance cost considerations, both for domestic firms and for

multinational entities not subject to mandatory application. Generally, data on these

questions are scarce or in some cases missing. The available survey data point however

to cost savings as explained in Section 5.1.1 and therefore serves the objective to increase

regulatory fitness. Time costs for setting up a new subsidiary in a Member State are

estimated to decrease 62-67% for the CCCTB. Focussing on recurring costs, i.e. ignoring

one-off switching costs, the Impact Assessment estimates a decrease in time spent on

compliance activities by 8% after implementation of the CCCTB. Based on these time

reductions one could endeavour a rough calculation of the order of total cost savings that

would result under the CCCTB. If 5% of medium-sized companies expand abroad, a one-

off cost saving of around EUR 1 billion could be expected. If all multinational entities

apply the CCCTB recurring compliance costs could go down by about EUR 0.8 billion.

With regard to the costs of tax administrations, the parallel application of national CIT

systems and the CCCTB will increase administrative burden in tax administrations since

two, albeit similar taxes need to be managed. However, since multinational entities under

the scope of the CCCTB will file only one tax declaration in the EU the total amount of

tax declarations should decline and ease the burden for tax administrations. Also, the fact

that no more transfer pricing documentation is necessary in the EU will reduce the

burden on administrations – in line with increasing regulatory fitness.

5.9.

Choice of the corresponding policy instrument

It is beyond doubt that binding legal rules are necessary for providing solutions, through

a common legislative framework, to the problems identified earlier as distortions to the

single market. Soft law would risk not being implemented by Member States at all or

could lead to a piece-meal approach. Such an outcome would be highly undesirable. In

addition to creating legal uncertainty for taxpayers, non-binding rules could jeopardise

the objectives for a coordinated and coherent corporate tax system in the single market.

In addition, as the architecture of the common tax base should be expected to impact on

national budgets, especially through the formula apportionment, it is critical that the rules

which define its composition be applied consistently and efficiently. This is far more

likely to be achieved through binding law.

Based on Article 115 of the Treaty on the Functioning of the European Union (TFEU),

which is the legal base used for legislating in direct taxation, "the Council shall, acting

unanimously … issue directives for the approximation of laws, regulations and

administrative provisions of the Member States as directly affect the establishment or

functioning of the internal market." The Treaty is therefore prescriptive that in direct

taxation, legislation shall exclusively be in the form of directives. According to Article

288 TFEU, a directive shall be binding, as to the result to be achieved, upon each

Member State to which it is addressed, but shall leave to the national authorities the

choice of form and methods for achieving this result. In this vein, the directive should

remain general in nature since technicalities and the minute detail should be left to

Member States to decide.

ONITORING AND EVALUATION

6.1.

Monitoring arrangements

The Commission will monitor the implementation of the legal proposal and its

application in close cooperation with the Member States. Monitoring in a continuous and

systematic way will allow identifying whether the policy proposal is applied as expected

and addressing implementation problems in a timely manner. Collection of factual data

of the suggested monitoring indicators will also provide the basis for the future

evaluation of the CCCTB. Given the specificities of the proposal, the monitoring will

cover both phases of the staged approach set out in the preferred option.

In terms of operational objectives, the number of intra-EU profit shifting arrangements

should be significantly reduced compared to the status quo since the CCCTB makes the

kom (2016) 0685 - Ingen titel

current practices obsolete.

108

The corresponding indicators presented in Table 17 are a

selection of those suggested by the OECD/G20 BEPS project (Action 11), slightly

modified to fit the context of the CCCTB initiative. For other companies the CCCTB is

optional, but it is generally designed to be attractive for all businesses. The operational

goal is to have a large number of firms opting into the system, ideally from all sectors of

the economy. The operational objective to ensure that profit taxation that does not distort

financing decisions is (i) to reduce the difference in the cost of capital for debt and equity

and (ii) to reduce the debt-equity ratio in companies. High take-up rates of the R&D tax

incentives are the relevant operational objective to measure progress towards the goal to

enhance investment in business R&D.

To measure the operational objectives, in-depth analyses is necessary. The data needed is

micro-panel data for companies, as well as national accounts data and information from

tax administrations, for instance on the take-up of the R&D allowance under the CCCTB.

To measure the effects econometrically a period of five years after the introduction is

necessary to produce statistically relevant results.

In compliance with the principle of subsidiarity, the relevant information should be

gathered primarily by the Member States' tax administrations when data on tax

compliance and the use of the system is concerned. Micro-data on companies is available

from external data providers.

Evaluation

The evaluation of the CCCTB should assess the extent to which the outlined objectives

have been met. It will also analyse the extent to which the expected simplifications for

the targeted stakeholders have materialized and assess the related administrative and

regulatory burden. Considering the phased approach of the CCCTB and allowing for

impacts to materialize and to be observed after the implementation of the policy, an

evaluation should be carried out three to five years after the implementation of the

second phase of the proposal. The Commission will report on the evaluation results in the

form of an evaluation report.

LOSSARY

Aggressive tax planning (see also: Tax planning):

In the Commission

Recommendation on aggressive tax planning (C(2012) 8806 final), aggressive tax

planning is defined as “taking advantage of the technicalities of a tax system or of

mismatches between two or more tax systems for the purpose of reducing tax liability.

Aggressive tax planning can take a multitude of forms. Its consequences include double

deductions (e.g. the same loss is deducted both in the state of source and residence) and

double non-taxation (e.g. income which is not taxed in the source state is exempt in the

state of residence)”.

Allowance for corporate capital (ACC)

is a corporate tax system where corporations

may deduct a defined return on total capital (both equity and debt) from the corporate

income tax base. It achieves full financing neutrality between debt and equity at the

corporate level.

Allowance for corporate equity (ACE)

is a corporate tax system where interest

payments and a defined return on equity can both be deducted from the corporate income

tax base. It moves the system closer to financing neutrality between debt and equity at

the corporate level.

Allowance for growth and investment (AGI)

is a corporate tax system where interest

payments and a return on equity can both be deducted from the corporate income tax

base. It moves the system closer to financing neutrality between debt and equity at the

corporate level. It goes some steps further than ACE because it removes tax avoidance by

cascading the benefits (the funds injected in a group benefit from deductibility only once)

and uses an incremental system based on a moving reference year.

Anti-Tax Avoidance Directive (ATAD)

is an EU Tax Directive which lays down rules

against tax avoidance practices which directly affect the functioning of the single market.

Anti-Tax Avoidance Package (ATAP)

is a package of actions which includes legally-

binding anti-avoidance measures necessary to reduce aggressive tax planning. It is part of

the action plan on corporate taxation for fairer, simpler and more effective corporate

taxation in the EU.

Base erosion and profit shifting (BEPS project):

Tax planning strategies that exploit

gaps and mismatches in tax rules to artificially shift profits to low or no-tax locations

where there is little or no economic activity, resulting in little or no overall corporate tax

being paid. The OECD and the EU have developed specific actions to give countries the

tools they need to ensure that profits are taxed where economic activities generating the

profits are performed and where value is created, while at the same time giving

enterprises greater certainty by reducing disputes over the application of international tax

rules, and standardising requirements.

Common consolidated corporate tax base (CCCTB)

is a policy proposal of the

European Commission consisting of the harmonisation of the tax base of corporations at

EU level. It also includes consolidation and apportionment of the tax base of corporation

groups.

kom (2016) 0685 - Ingen titel

Common corporate tax base (CCTB)

consists of the harmonisation of the tax base of

corporations at the EU level, but does not include the element of tax consolidation which

is part of the CCCTB.

Comprehensive business income tax (CBIT)

refers to a corporate tax system where

neither interest payments nor the return on equity can be deducted from corporate profits,

and are thus both fully subject to corporate income tax. It equalises the tax treatment of

debt and equity finance at the corporate level.

Controlled foreign corporation (CFC)

is a foreign corporation whose income (or some

part of it) is deemed to be generated (and hence to be taxed) in the residence country of

the multinational group if certain conditions are met (usually this condition is that the tax

rate in the foreign country is lower than a set percentage of the tax rate in the country

implementing the CFC rule). The particular definition of the foreign corporations subject

to these rules varies across jurisdictions, but it is generally based on a control percentage.

Corporate income tax (CIT)

is a direct tax levied on the profits of corporations. The tax

rate payable varies across jurisdictions.

Cost of capital (CoC)

is a measure of the cost of either debt and/or equity. It is used to

assess the cost of new investments.

Cost of capital allowance (CoCA):

The term refers to a corporate tax system where the

cost for both debt and equity finance is captured by a defined allowance which is

deductible from the corporate tax base; similarly, at the investor's level, the income tax

base increases by a defined return on the investments, which corresponds to the defined

allowance and can be taxable. The amount of the allowance/return is computed as the

product of the relevant assets/investments multiplied by a CoCA rate. This system

equalises the tax treatment of debt and equity finance at the corporate and investor level.

Country-by-country reporting (CBCR)

refers to the requirement that large

multinational entities (those with consolidated revenues of at least EUR 750 million)

have to submit a report on tax-related information to the jurisdictions in which they do

business on an annual basis.

Debt-equity tax bias/debt bias

can be the result of operating a corporate tax system

which favours financing by debt, rather than by equity. This is achieved by treating

interest payments as a tax deductible expense whilst no equivalent deduction is granted

for the return on equity (mainly, dividends).

Double taxation

is an international taxation scenario in which the same taxable object is

subject to taxation in two or more jurisdictions.

Earnings before interest, tax depreciation and amortisation (EBITDA)

is an

accounting measure of the net earnings of a company. It excludes interest, taxes,

depreciation and amortisation expenses.

Effective average tax rate

is a tax rate calculated from the nominal tax rate and the

definition of the tax base. Particularly, this effective tax rate is based on total investment

income.

kom (2016) 0685 - Ingen titel

Effective marginal tax rate

is a tax rate calculated from the combination of the nominal

(i.e. statutory) tax rate and the definition of the tax base (i.e. the taxable profit).

Particularly, this effective tax rate is based on additional investment income.

Formula apportionment

is an equation used to allocate the tax base of multinational

corporations between the entities of the group.

Hybrid mismatches:

This refers to the situation where, as a result of disparities amongst

national laws, the same entity or financial instrument is characterized differently, as far

as its tax treatment is concerned, in two or more States (e.g. an entity is treated as a

partnership in one jurisdiction and as a corporation in another; a financial instrument

qualifies as deductible interest in one jurisdiction and as tax exempt dividend in the

other). Taxpayers often set up arrangements to exploit such mismatches for the purpose

of lowering their overall tax burden.

Intellectual property

is a set of intangible assets owned by a company, which are legally

protected by patents, trademarks, copyrights or other type of intellectual property rights.

Joint Transfer Pricing Forum

is an EU forum of experts that assists and advises the

European Commission on transfer pricing tax issues. It was created by a Commission's

Decision of 25

January 2011.

109

The JTPF has one representative from each Member

State's tax administrations and 18 non-government organisation members. It is chaired by

an independent chairperson. The JTPF works within the framework of the OECD

Transfer Pricing Guidelines and operates on the basis of consensus to propose to the

Commission pragmatic, non-legislative solutions to practical problems posed by transfer

pricing practices in the EU.

Multinational entities/companies/enterprises

are corporations that operate across

different jurisdictions.

Non-financial corporations

are corporations not belonging to the financial sector.

Profit shifting

is an intra-group tax planning strategy of multinational entities consisting

of shifting profits from the entities of the group operating in high tax paying countries to

other entities operating in low tax paying countries.

Research & Development (R&D):

Research: all original and planned investigation undertaken with the prospect of gaining

new scientific or technical knowledge and understanding.

Development: the application of research findings or other knowledge to a plan or design

for the production of new or substantially improved materials, products, devices,

processes, systems or services before the start of commercial production or use.

Small and medium-sized enterprises (SMEs)

are defined by the European Commission

as having less than 250 persons employed. They should also have an annual turnover of

up to EUR 50 million, or a balance sheet total of no more than EUR 43 million

(Commission Recommendation of 6 May 2003).

Special-purpose entities

are legal entities established to perform specific functions

limited in scope or time, which has little or no production, is often a subsidiary and has

as a core business function financing its group activities or holding assets and liabilities

of its group.

Treaty on the Functioning of the European Union (TFEU)

is one of the Treaties on

which the EU is founded. It organises the functioning of the Union and determines the

areas of, delimitation of, and arrangements for exercising its competences.

Tax avoidance:

According to the OECD glossary of tax terms, tax avoidance is defined

as the arrangement of a taxpayer’s affairs in a way that is intended to reduce his or her

tax liability and that - although the arrangement may be strictly legal - is usually in

contradiction with the intent of the law it purports to follow.

Tax evasion:

According to the OECD glossary of tax terms, tax evasion is defined as

illegal arrangements where the liability to tax is hidden or ignored. This implies that the

taxpayer pays less tax than he or she is legally obligated to pay by hiding income or

information from the tax authorities.

Tax planning (see also: Aggressive tax planning):

According to the OECD glossary of

tax terms, tax planning is an arrangement of a person’s business and/or private affairs in

order to minimize tax liability.

ROGRAMME

The re-launch of a proposal for a Common Consolidated Corporate Tax Base (CCCTB)

was prepared under the lead of Directorate General for Taxation and Customs Union.

Within the Agenda Planning of the European Commission, the project is referred to

under item 2016/TAXUD/006. In the Commission Work Programme for 2016, the

Commission committed under the header "Deeper and Fairer Internal Market with a

Strengthened Industrial Base" to propose a staged approach starting with agreeing a

mandatory tax base.

2. O

RGANISATION AND

IMING

Work on the re-launch of the CCCTB started in July 2015.

An Inter-services Steering Group assisted DG Taxation and Customs Union in the

preparation of this Impact Assessment report. The Steering Group was set up on

24/08/2015 and included colleagues from DG Communication Networks, Content and

Technology; DG Competition; DG Economic and Financial Affairs; DG Environment;

DG Financial Stability, Financial Services and Capital Markets Union; DG Internal

Market, Industry, Entrepreneurship and SMEs; DG Justice and Consumers; DG Research

and Innovation; DG Taxation and Customs Union; DG Trade; the Joint Research Centre;

the Legal Service; and the Secretariat-General.

The Steering Group met on four occasions between September 2015 and June 2016. The

last meeting of the Steering Group took place on 13 June 2016. At each occasion, the

members of the Steering Group were given the opportunity to provide comments in

writing on the draft versions of the documents presented.

ONSULTATION OF THE

EGULATORY

CRUTINY

OARD

The impact assessment report was reviewed by the Regulatory Scrutiny Board on 20

July 2016. Based on the Board's recommendations, the impact assessment has been

revised in accordance with the following points.

(1) The introduction (Section 1) has been amended to clarify and better explain the policy

context. The other sections have been revisited to ensure consistency with the new

introduction. A box on the 2011 proposal has been introduced in Section 1.

(2) The intervention logic was refined and is explained in Section 3 which now also

includes a table which provides an overview of the links between problems, objectives

and policy options as well as the general context. The choice of the preferred option for

the scope has been elaborated more vis-à-vis the summary table 8.

(3) Throughout the text the references to baseline scenario have been clarified and

streamlined to better explain the assessment of options. A new section on EU value

added has been introduced in Section 2.5.

kom (2016) 0685 - Ingen titel

(4) Options have been numbered and further clarified with regard to the 2011 proposal.

More information on the fiscal impact of the options has been added in the subsections of

Section 5 and in annexes XII and XIII. . Section 5.5 has been expanded to explain better

the implications of a staged approach.

(5) The REFIT elements have been added in Section 5.8 in the discussion of the preferred

policy option.

4. E

XTERNAL

XPERTISE

DG Taxation and Customs Union used external expertise to substantiate the discussion of

the design of the CCCTB with extensive quantitative analysis. These projects were not

triggered specifically by the decision to propose a re-launch of the CCCTB itself, but part

of continuous analysis of policy issues in the area of corporate income taxation by DG

TAXUD.

On the basis of administrative agreement between DG Taxation and Customs Union and

the Joint Research Centre (JRC)

110

, the JRC Institute for Prospective Technological

Studies (IPTS) has provided modelling support in the area of corporate tax policy. By

means of econometric analysis and computable general equilibrium model, IPTS has

analysed corporate income tax policy development and reforms.

Within the Framework Service Agreement with the Centre for European Economic

Research (ZEW) on the "Provision of effective tax rates in the context of an enlarged

European Union and related supporting services"

111

, DG TAXUD signed specific

contracts for the analysis of effective tax rates. One of these studies explored potential

effects of aggressive tax planning on the effective marginal and effective average

corporate tax rate of multinational corporations

112

. In another study, the ZEW analysed

the "The Effects of Tax Reforms to Address the Debt Bias on the Cost of Capital and on

Effective Tax Rates".

For the studies prepared by the JRC and the ZEW, Annex 4 provides more detailed

information on the model structure used, underlying assumptions and sensitivity of

results.

In addition to these specific studies commissioned by DG TAXUD, there exist a number

of other recent external studies of particular relevance for the design of a CCCTB. A list

of the scientific papers referred to in the Impact Assessment is provided in Section 8 of

the Impact Assessment report.

Annex II: Stakeholder Consultation – Synopsis Report

1. I

NTRODUCTION

On 17th June 2015 the Commission published an action plan for a Fairer and Efficient

Corporate Tax System which proposed 5 key areas for action in the coming months

(COM (2015) 302). The re-launch of the Common Consolidated Corporate Tax Base

(CCCTB) proposal lies at the heart of the action plan. It is presented as an overarching

objective which has the potential to be an extremely effective tool for meeting the twin

objectives of fairer and more efficient taxation.

The Inception Impact Assessment has been published on the EUROPA webpage early in

the process to inform the public of the setup and scope of the re-launch of the CCCTB.

The Commission has not received any direct feedback on this Inception Impact

Assessment.

The Commission has furthermore run an open public consultation to consult all

stakeholders and offer interested parties the possibility to provide their input to the re-

launch of the CCCTB. 175 participants participated in this consultation.

The percentages given in this factual summary correspond to the responses submitted by

stakeholders to the open public consultation. Beyond a statistical analysis of the data, the

summary also provides a qualitative assessment of the valued opinions and input

received.

REAKDOWN OF

ARTICIPANTS

The majority of respondents were trade or business associations and companies (42% and

32% of responses, respectively). A comparably high share of responses came from

Bulgarian companies (about 20%). The second largest group of responses came from

trade/business associations in Belgium (some being representations to the EU).

Respondents indicating "Other country" were located in Norway, Russia, South Africa,

USA – or did not want to single out a specific country when their association or company

group is located in many different countries.

A majority of participating private individuals and civil society organisations share the

view that CCCTB can be an effective tool against aggressive tax planning while retaining

its attractiveness to business. A number of respondents mentioned that a common set of

rules for calculating the corporate tax base, accompanied by consolidation, would prevent

profit shifting, provide greater transparency and align economic activity with taxation.

This will also make the EU a more attractive place for foreign firms to invest in and

make doing business easier.

Many companies also broadly agree with this objective. Respondents who don't agree

argue that the CCCTB should be focussed on removing cross-border obstacles in order to

reduce tax compliance costs.

Furthermore a large majority of respondents from NGOs, public authorities and other

respondents shared the view that the CCCTB could be an effective anti-avoidance tool

within the CCCTB zone. For arrangements involving third countries, or tax avoidance by

multinationals headquartered outside the CCCTB, the prevailing opinion is that the

OECD BEPS project outcomes will provide more targeted and global responses and that

diverging from OECD/BEPS could leave EU business at a competitive disadvantage.

Therefore the CCCTB ''should not go faster and further than the rest of the world in

implementing BEPS recommendations''.

kom (2016) 0685 - Ingen titel

Some respondents had some concerns about the overall administrative burden that many

new rules could place on business and the risk that shifting the focus towards aggressive

tax planning may undermine the original purpose of the CCCTB, i.e. to support EU

business and make the internal market more business friendly. Concerns have also been

expressed about the risk that the interaction between the formulary approach followed by

the CCCTB and the arm's length principle strengthened by the OECD BEPS project

could potentially lead to double taxation.

The Commission envisages re-launching the CCCTB in a staged approach which will consist of 2 steps:

Firstly, agreement on the tax base, secondly, moving on to consolidation. What are your views on the

staged approach?

Among the respondents to the public consultation, in general more respondents were in

favour of the staged approach than against. For those in favour of a staged approach,

consolidation is essential and its introduction should follow as quickly as possible

without delay. Therefore the first stage should incorporate a procedural path towards the

second stage and a clear timeframe/ commitment to move to consolidation should be

introduced at the outset.

Only the group of NGOs, public authorities and other respondents was – with a big

majority – in favour of introducing the CCCTB in one move. These respondents argued

that delaying consolidation would create uncertainty and a risk of more tax competition.

kom (2016) 0685 - Ingen titel

Among the remaining respondents, some are concerned that there is little point in

achieving a CCTB when there may be difficulty making further progress; a few are in

principle against the concept of CCCTB; and a couple support implementing the CCTB

as a stand-alone and not depending on consolidation.

It is a priority of the Commission to promote discussion in Council of certain BEPS-related international

aspects of the common base before the re-launched CCCTB is proposed. The aim will be to arrive at

consensus on how to implement certain OECD anti-BEPS best practice recommendations in a uniform

fashion across the EU. The intention would be to create a common playing field in defending the single

market against base erosion and profit shifting.

What are your views on agreeing on such a common approach?

In the responses to the consultation, NGOs stated their views that OECD has fallen short

of expectations and that it is now up to the EU to go beyond the BEPS recommendations

in order to close the remaining tax loopholes and develop a solution to the widespread

phenomenon of tax avoidance. Only one reply from civil society organisations showed

opposition to a common approach to implementing OECD anti-BEPS best practice

recommendations. Companies believe that it is crucial for multinational entities to have

stability and legal certainty. Accordingly, if the proposals of the OECD BEPS action plan

were to be implemented by EU Member States unilaterally without any harmonisation or

coordination, the basic principles of the OECD BEPS action plan would be violated and

the chances to achieve its aims would be severely harmed. Only a small percentage of

this category's respondents are opposed to the Commission's approach.

kom (2016) 0685 - Ingen titel

There is a strong support from registered business/professional associations and

consultancy/law firms for the common implementation of the OECD BEPS principles

through the EU. However the majority believes that EU anti-BEPS measures should not

go beyond the OECD recommendations in order to avoid competitive disadvantages for

EU companies.

As to the timing and modalities, some proposed an anti-BEPS directive to be

supplemented with a strong dispute resolution system, while others questioned whether

the CCCTB would be an appropriate mechanism to implement anti-BEPS measures

before the common tax base has been agreed. A few objected that applying a one size fits

all approach to tax legislation within the EU does not take into account the needs of

different Member States.

3.2 Scope of the CCCTB proposal

The Commission considers making the new proposal for a CCCTB obligatory for all EU companies which

are part of a group. A group can be formed:

Between parent and subsidiary companies where there is a holding of more than 50% of the voting rights;

and direct or indirect holding amounting to more than 75% of capital or more than 75% of the profit

rights); or

Between a Head Office and its permanent establishment where a company has one or more permanent

establishment in other Member States.

What are your views on making the proposal for a

CCCTB obligatory for all EU companies which are part

of a group?

Would you suggest a different approach to defining who should be required to use the CCCTB? If yes,

please explain your suggestion briefly.

Respondents from NGOs, public authorities and other respondents advocate a mandatory

CCCTB given that an optional one would allow companies to choose the more profitable

system, hence creating new arbitrage opportunities. A substantial number of respondents

consider that the co-existence of two systems, the domestic one and the CCCTB, could

cause the Internal Market to deteriorate and therefore propose a broader scope for the

CCCTB to include all companies with a taxable presence in the EU.

Companies' opinions appear to be more divided. 40% of them support the Commission

proposal. On the other hand 30% of them are opposed to a mandatory CCCTB. Even

among the supporters, the definition of "group" gives rise to different views. Some

respondents propose to include only cross-border entities while others prefer a threshold

based on the turnover of the company.

The majority of business/professional associations and consultancy/law firms do not

support this approach. The divergent opinions expressed on this question include the

following: "Making the system optional could create an incentive for EU governments to

create a system that is superior to existing individual systems and to give businesses a

practical alternative." "For governments an optional system entails the benefit of a

gradual adoption by businesses, thereby ensuring a limited short term impact on

corporate tax".

Business and professional associations expressed concern about the definition of group

for which the system should be mandatory. Considering the difficulty of introducing the

concept of group for jurisdictions that have very different legal accounting models, some

proposed that the criteria for defining a group should be based on the accounting

directive.

The Commission envisages providing the following option:

Companies which would not be subject to the mandatory CCCTB - because they do not fulfil the

requirements of being part of a group - could still have the possibility to apply the rules of the system.

What are your views on offering non-qualifying companies the option to apply the rules?

Overall, a clear majority of the respondents to the consultation supports the possibility

that non-qualifying companies could opt for applying the common tax base.

Most enterprises and business/professional associations support optionality for all

companies. There is some agreement that a system mandatory for qualifying companies

should allow non-qualifying companies to opt in. Others believe that allowing some

companies to opt in would undermine the level playing field the CCCTB wants to create

and will distort the system, opening it up to possible abuses and tax planning.

3.3 Anti-avoidance elements

In view of recent developments, the CCCTB system should include more robust rules to defend itself

All measures have received a certain support but, overall, there is a general demand for

more robust CFC rules. In particular, many NGOs call for "full-inclusion" CFC rules

which means: " treating all foreign affiliates of EU resident parent companies as CFCs so

that the group consolidated profits are subject to tax in the resident country, with a full

credit for all equivalent foreign taxes paid, which under the CCCTB should be

apportioned among the group’s E affiliates by an appropriate formula. This would

protect the tax base of both source and residence countries. They should certainly not be

kom (2016) 0685 - Ingen titel

limited to income from transactions with the parent company, and there should be no

exemptions based on criteria such as effective exchange of information, as profits may

also be shifted into cooperative jurisdictions. Full-inclusion CFC rules would be easier to

apply than attempting to distinguish between active and passive income, or using a

threshold such as 40% of the taxpayer’s effective tax rate."

Most of civil society respondents who chose 'other suggestion', argue that consolidation

and harmonisation would make the listed elements unnecessary.

From the companies' perspective, improving arbitration seems to be essential.

The most recurrent 'other suggestion' from business/professional associations and

consultancy/law firms include:



a double tax avoidance mechanism (arbitration) between EU and non-EU country

with a mandatory system for the EU through a directive;

consistency between the anti-avoidance measures incorporated in the CCCTB and

those advocated by the OECD;

coordination with non-EU countries to avoid relocation of business activities

outside the EU.

One respondent's comments summarise the prevailing opinion of this category:

"Effective anti-avoidance rules are necessary under a CCCTB but they should not trigger

any unintended consequences such as having a negative effect on investments into the

EU or the international competitiveness of EU based groups".

3.4 Hybrid Mismatches

Hybrid mismatches are the result of disparities in the tax treatment of an entity or financial instrument

under the laws

of two or more States. Currently, arrangements can be set up to exploit such mismatches for

the purpose of lowering their overall tax burden. The risk of such arrangements would be removed in

transactions between enterprises applying the common tax base rules within a consolidated group. It would

however persist in relations with enterprises outside the common rules as well as during step 1 of the

staged approach to a CCCTB, in the absence of tax consolidation amongst the companies applying the

common rules.

One option to address hybrid mismatches would be to require enterprises to follow in a Member State the

classification of entities and/or of financial instruments adopted in the other Member State or the third

country which is party to the transaction.

In your view, can hybrid mismatches be effectively addressed through any other measures than the one

suggested above?

The majority of NGOs and public authorities propose full-inclusion CFC rules as a key

element to catch hybrids, accompanied by a credit for taxes paid abroad. One third

doesn't know. A few suggest a public country by country report as an effective measure

to cover more hybrid mismatches, others stress that consolidation would solve the

discrepancies.

A vast majority of companies answered that they don't know, mainly driven by the

responses of small and medium size enterprises. Only a few respondents, including

multinationals, mentioned that hybrids could be avoided through OECD anti-BEPS

actions.

Among registered business associations, some believe that the EU should not diverge

from the OECD recommendations on this topic. Some make a distinction between intra-

EU situations, where a consolidated CCCTB from the beginning could solve the issue,

and extra-EU situations where OECD/BEPS covers the issue. A couple of respondents

say that hybrid instruments are not necessarily a result of tax planning.

3.5 Research and Development (R&D)

In the currently pending CCCTB proposal, the Commission has proposed a favourable treatment of costs

for Research and Development (R&D) by making these costs fully deductible in the tax year they are

What are your views on the existing framework for R&D?

A large majority of respondents expressed strong support for the existing framework.

Many among the responding NGOs, public authorities and other respondents replied

"other", mainly calling for clear definitions. It was also remarked that deduction of R&D

costs should be strictly limited to genuine research and development costs in order to

subsidise only real innovation.

The overwhelming majority of companies believe it is important to allow deduction of

R&D and support the existing framework.

60% of respondents from registered business/professional associations and

consultancy/law firms also support the existing framework. 17% are neutral, and a small

number don't know. The other respondents from this category mostly ask for a clear

definition of R&D, possibly consistent with the accounting definitions, or believe that

"Member States should have flexibility to design tax policy for R&D within the BEPS

work in order for the EU to remain attractive compared to extra-EU".

101

kom (2016) 0685 - Ingen titel

One option for rendering the CCCTB more favourable to promoting R&D could be to introduce more

generous provisions for deducting R&D costs, such as super deductions which are currently applied by a

number of Member States (e.g. Croatia, the Netherlands and the UK)?

What are your views on making the existing framework for R&D more favourable?

Would you suggest an alternative scheme? If so, please explain in your response and/or provide further

Most of the NGOs, public authorities are against R&D incentives for the reason that they

can be used for aggressive tax planning. They argue that there are other means to

stimulate R&D without risking new abuses. Some of them point out the lack of clear

definitions. Some respondents would like to go further and reverse intellectual property

regimes such as patent boxes.

With a completely different approach, almost all companies would welcome a more

favourable framework for R&D as it would foster the economy.

Half of the respondents from business/professional associations and consultancy/law

firms are in favour of making the existing framework for R&D more favourable. Their

suggestions include:



Super deductions (mostly);

Introduction of a common incentive rule such as an incremental deduction for

R&D or an EU Intellectual Property box;

102

kom (2016) 0685 - Ingen titel



Tax credits (cash premiums) because super deductions tend to most benefit

companies that are profitable;

Above-the-line R&D expenditure credits in EU countries so that even loss-

making companies can benefit from them.

Some respondents from this category believe that any EU initiative needs to build on the

recent work of OECD and/or that Member States should be allowed to retain their

flexibility in designing their own national R&D policies.

3.6 Debt equity bias

Corporate tax systems usually favour debt-financing over equity-financing by treating interest payments as

a tax deductible expense with no equivalent deduction for the return paid to equity.

44% of respondents agree that the debt bias shall be addressed against 13.1% who think

it should not. The 'yes' surpasses the 'no' in all categories of respondents, even though a

large share of business/professional associations and consultancy/law firms chose the

category 'other'. The majority of those who agree with addressing the debt bias stress

distortions of economic decisions, notably related to investment.

Those among business/professional associations and consultancy/law firms who believe

that debt/equity bias should not be addressed as part of the CCCTB argue that the

CCCTB is primarily focused on the taxation of corporate groups and/or OECD/BEPS

103

kom (2016) 0685 - Ingen titel

Action 4 recommendations need to be put in place and tested before considering a new

set of rules.

Some argue that equity and debt are two different instruments with different rights and

different costs and, as such, the tax treatment should not necessarily be the same and that

a different treatment is justified for the banking sector. A couple think that a detailed

assessment of the budgetary impact for each Member State is a pre-requisite; others

suggest that since equity financing is not readily available in the EU any changes should

not further impact the financing options available in the EU. A few respondents from this

category replied in a completely positive manner.

The corporate tax debt equity bias could be addressed via three possible

policy options.

Option 1 is the Comprehensive Business Income Tax (CBIT) that disallows any financing costs as

deductible expense.

Option 2 is the Allowance for Corporate Equity (ACE) that allows the deductibility of actual interest

payments and of a

notional interest on equity.

Option 3 is the Cost of capital Allowance (CoCA)

that allows the deductibility of a notional interest on

capital (equity and debt).

In your view, which option would be best suited to address the corporate debt bias?

there is resounding support for ACE. Several of those who support ACE argue that

interest limitation shall be limited to OECD BEPS Action 4 and ask whether the proposal

is in line with OECD BEPS Action 4. Like the companies, a strong majority of

business/professional associations and consultancy/law firms expressed its preference for

ACE. Some warn against the risk of raising tax rates and levelling down of deductibility

of interest to pay for ACE.

3.7 Temporary mechanism for cross-border loss relief

The Commission envisages proposing a temporary mechanism for cross-border loss relief with recapture

until the consolidation step (CCCTB) is agreed. The aim will be to balance out the absence of the benefits

of consolidation during the first step (CCTB) of the proposal.

What are your views on such a temporary mechanism for cross-border loss relief?

The majority of the companies who responded argue that the lack of mechanisms

available to offset cross border losses is currently one of the major obstacles to the

completion of the single market and reduces the competitiveness of EU. In addition, a

few respondents suggest that the cross-border loss offset should be extended to non-EU

companies and permanent establishments, given that competitiveness of EU companies

needs to be regarded on a global scale.

In addition a strong majority of respondents from business/professional associations and

consultancy/law firms also believe that consolidation is essential. However, they would

accept a transitory and temporary cross-border loss relief as a second best approach.

Some envisage resistance from Member States in offering wide-ranging cross-border

relief as taxes should be paid where value is created. Others advocate the introduction of

105

kom (2016) 0685 - Ingen titel

an EU wide regime, not linked to the CCCTB, to be implemented into domestic

legislation.

Conversely most NGOs and civil society organizations don't support the introduction of a

temporary mechanism for cross-border loss relief. They believe that postponing

consolidation indefinitely while introducing a cross-border loss relief risks removing the

main benefit of the proposal, while shrinking the taxable base of multinational companies

and opening up the system to new types of aggressive tax planning.

3.8 Additional information provided by respondents

Is there anything else you would like to bring to the attention of the Commission?

The Commission services have analysed and factored into the summary all additional

comments and papers that were submitted.

kom (2016) 0685 - Ingen titel

Annex III: Who is affected by the initiative and how

The objective of this annex is to set out the practical implications of the initiative for

different types of companies and for national tax administrations.

The initiative directly affects companies falling under the mandatory scope, companies

that are given the possibility to opt for the CCCTB and tax administrations. In a first step,

all companies active in the EU would have to determine whether they fall under the

mandatory application, depending on the threshold on consolidated turnover.

Large companies

above the high turnover threshold that are subject to mandatory

application of the CCCTB would be faced with new rules to compute the tax base in the

Member States in which they are active, including the rules on consolidation and formula

apportionment. This would inter alia entail a one-off cost for switching to new rules on

(i) depreciation, (ii) the valuation of assets and liabilities, and (iii) the deductibility of

expenses and exempt revenues, and for determining (iv) which parts of a group fall under

the CCCTB definition of a group (and consolidating the EU-wide tax base for this group)

and (v) the information required on the formula apportionment factors (assets,

employment and wage bill, sales by destination) for each group member.

It is estimated that a vast majority of companies under the mandatory scope would be

active cross-border (at least 80% for a threshold of EUR 750 million; at least 75% for a

threshold of EUR 500 million, see table below). For companies active in several EU

Member States, it is expected that the recurrent compliance costs will decrease

considerably. The same is true for domestic companies that would wish to expand their

operations to another EU Member State.

The fairly high turnover threshold envisaged under the preferred option would imply that

only a small share of groups would be subject to mandatory application. By means of

example, for a threshold of EUR 750 million the application would be compulsory for an

estimated 1.6% of company groups the CCCTB. It is estimated that at most 19% of the

groups subject to compulsory application are purely domestic groups.

SMEs

and other companies which are not obliged to apply the CCCTB are free to stay

within their national systems and would as such not be affected by the initiative. Those

among these companies that consider the possibility to opt in would have to conduct a

cost-benefit assessment to decide whether they would benefit from applying the CCCTB.

Such cost-benefit analysis would also factor-in the costs for switching to the new system.

Tax administrations

will also incur costs for implementing the new system, notably on

IT and staff training. There will also be a need to coordinate in the EU the uniform

implementation and practical application of the new rules. Eventually, tax

administrations are expected to benefit from reduced dealings with transfer pricing issues

and a reduced 'case number' to the extent that the tax affairs of a company group is

mainly dealt with by the administration of the Member State where the parent resides.

Since the CCCTB would not be made mandatory for all firms, the burden for national

administrations may overall go up slightly due to the required maintenance of two

parallel systems.

Annex IV: Analytical Models used in preparing the Impact Assessment

1. CORTAX: A

MODEL TO SIMULATE CORPORATE TAX POLICIES

1.1. Brief Description of the Model

The CORTAX model is a computable general equilibrium model designed to evaluate

the effects of corporate tax reforms in 28 EU countries capturing the optimal behaviour

of all agents in the economy. In the model, each country is assumed to have the same

structure in terms of consumption, savings, production and public finances (though the

data are country-specific). Countries are linked to each other via international trade in

goods markets, international goods markets and investment by multinationals. The model

also includes Japan, USA and a tax haven.

Firms are divided into three categories: multinationals headquarters, their subsidiaries

located abroad and domestic firms that only produce in their country of residence.

Multinationals and domestic firms differ to the extent that the former optimise profits

globally and are engaged in profit shifting activities across borders. Domestic firms pay

their corporate taxes in their country of residence according to the revenues generated in

this country only. Both domestic and multinational firms shift profits to tax haven to

reduce their tax burden. In the benchmark, all firms are equal and, whilst on aggregate

taxable profits are positive, there are random shocks affecting their revenues that can be

attributed to, for example, business cycle evolutions. These shocks may result in losses

that can be carried forward in the model.

In relation to government, there is a balanced budget where consumption and public debt

are a fixed proportion of GDP. Tax revenues and/or transfer payments adjust to keep a

constant public budget. The taxes included in CORTAX are taxes consumption and direct

taxes on income from corporate and labour, dividends, capital gains and interest.

Government consumption and government debt as a share of GDP are maintained

constant after a reform.

The effects of reforms can be expressed as changes in GDP, household consumption,

business investment and fiscal revenue. The model is elaborated using data from different

data sources including Eurostat, the OECD, the United Nations, the IMF and the Orbis

firm database (see Section 4.2 below for more details). In the present exercise, the model

has been constructed with a database for the year 2012. The structural description of the

model and the calibration process borrow heavily from Bettendorf et al. (2009b).

1.2. Model Validation and Peer Review

The CORTAX model has acquired a strong reputation among corporate tax experts. As

noted, the model was originally produced by CPB Netherlands, and has since been used

by experts affiliated to the Oxford University Centre for Business Taxation, the Erasmus

University Rotterdam, the Tinbergen Institute and CESifo. The model was previously

used in an Impact Assessment (European Commission, 2011a), which drew extensively

from a report produced for DG TAXUD (Bettendorf et al., 2009b). Among other policies,

the report analysed both a common corporate tax base and a common consolidated

corporate tax base for the EU.

The CORTAX model has been the basis for a number of publications in peer-reviewed

journals. Of particular note is Bettendorf et al. (2010a) in

Economic Policy

which

109

kom (2016) 0685 - Ingen titel

simulates a common consolidated corporate tax base (CCCTB) across the EU, with

further innovations of the ideas subsequently published in

Fiscal Studies

(Bettendorf et

al., 2010b). The issue of using CORTAX to analyse the debt bias in corporate taxation

was addressed in de Mooij and Devereux (2011b) published in

International Tax and

Public Finance.

An earlier publication in

The World Economy

used CORTAX to analyse

the impact of corporate taxation on the labour market (Bettendorf et al., 2009a). That the

model has stood up to the rigorous standards required to be accepted by journals of this

quality reflects the level of the theoretical and empirical work underlying the model, and

that it is appropriate for analysing key policy questions in the area of corporate taxation.

1.3. Discussions with External Experts

As noted in the previous section, the CORTAX model has been accepted within the

corporate taxation community for some years. The model has been used by leading

research institutes and universities, and work based around the model has been accepted

for publication in high-level, peer-reviewed academic journals in the area of fiscal policy.

Since this earlier body of work, the model data has been updated by the Tax Modelling

Group in JRC-Seville. This extensive recalibration process has been carried out in

conjunction with external experts, as appropriate. The team has collaborated closely with

Leon Bettendorf (CPB Netherlands), one of the original authors of the model, and lead

author for many of the reports and journal articles. Regarding the calibration, the team

has worked with Simon Loretz (Institute for Advanced Studies, Vienna), who produced

much of the data for the previous calibration of the model during his time at the Oxford

University Centre for Business Taxation, and was a co-author for the report that formed

the basis of the 2011 Impact Assessment (European Commission, 2011a).

1.4. Underlying Assumptions and Data Input

1.4.1 Baseline and key assumptions

In CORTAX, we account for two types of households: old and young. Their lifetime is

40-year periods each and their behaviour remains the same during the whole period.

Households maximise their intra-temporal utility function subject to a budget constraint,

where net savings from young workers (wages, current transfers and negative

consumption) are equal to negative value of net savings from old households. The effects

on welfare are calculated using the compensating variation. This is calculated as the

difference in transfers received by young households required to compensate the change

in utility.

Firms maximise their value subject to the production function and the accumulation

constraints on physical capital and fiscal depreciation. Total production is calculated as

the sum of production in all firms (domestic and multinationals) net of intermediate

inputs in foreign subsidiaries. Usually, the production function is a Cobb Douglas

combination of the fixed factor and the value added, which is a CES aggregate of labour

and capital. The model allows the parent company to charge a transfer price for intra-firm

deliveries that deviates from the equivalent price that would be charged if it had been an

inter-firm transaction (the ‘arms-length’ price), which reflects profit shifting in

multinationals. In the case of domestic firms, these practices are captured with the

existence of a tax haven. Profit shifting to tax havens depends on the difference between

the statutory rate in their respective countries and the tax rate in the tax haven.

110

kom (2016) 0685 - Ingen titel

The simulations are coded to ensure that the government budget remains balanced. This

is achieved in two ways. First, it is assumed that governments will adjust the corporate

tax rates to maintain constant corporate tax revenue, prior to any behavioural response

(i.e. ex-ante to the simulation). Any revenue changes due to the behavioural responses

(i.e. ex-post to the simulation) are accounted for by the government adjusting transfers to

retirees.

1.4.2 Key sources of macroeconomic and socio-economic data

The current calibration largely uses the same data sources as the original calibration of

CORTAX as outlined in Bettendorf and van der Horst (2006), though in a few cases

alternatives were used if these were considered more reliable, or the original source was

no longer available. The year 2012 was chosen as reference year for the calibration, as it

represented a good compromise between timeliness and completeness. The countries

covered are the 28 EU member states, the United States and Japan.

Population and employment statistics come from the United Nations and national

accounts data on income and expenditure are collected from OECD and Eurostat.

Purchasing power parity (PPPs) exchange rates are from the IMF and Eurostat and

general government consolidated gross debt as a percentage of GDP is from DG

ECF N’s Ameco Database. Additionally, CORTAX needs bilateral FD positions as part

of the calibration. For these, the modelling starts with the Eurostat bilateral positions.

Data on Foreign Direct Investment (FDI) flows by country of origin and country of

receipt are from Eurostat (financial account, direct investment, reporting economy). As a

number of countries have incomplete information on the country of origin of the inward

FDI stock, the modellers impute these values following the practice in Bettendorf and

van der Horst (2006), and a correction is made when the FDI data represent special

purpose entity activity.

Finally, CIT receipts as a percentage of GDP are from European and the OECD while

information on balance sheets and ownership structure are extracted from the Orbis

database, provided by Bureau Van Dijk. Although Orbis is a firm-level database, for the

purposes of the calibration it is only used to produce national-level estimates of debt

shares and of corporate investment shares (by type of asset) so as to calculate relevant

corporate tax parameters such as the cost of capital (financed via equity or debt).

1.4.3 Construction of the baseline and core policy simulations

The data described above is entered into the model, which provides a consistent and

connected framework for firms, household and governments. The data and the current

policies of each country are used to replicate the corporate taxation regime, and indeed

the production structure and household behaviour. The corporate taxation regime is

necessarily stylised (for example, not every deduction can be included), though the

simulations confirm that at a macro-level the CIT regimes are replicated well.

The core simulations have been chosen to reflect potential policy options for

harmonisation of corporate tax bases in the EU. Following the proposal (European

Commission, 2015a), two main reforms are considered: the common corporate tax base

(CCTB), and the common consolidated corporate tax base (CCCTB). Both reforms are

assumed to be mandatory for multinationals only (though the work also simulates the

case where domestic firms participate). The CCCTB proposal offers a holistic solution to

111

kom (2016) 0685 - Ingen titel

profit shifting. It combines a common tax base together with consolidation of each

multinational group's profit, removing the incentive to engage in profit shifting. Under

this reform, the consolidated tax base must then be apportioned to each country

according to an agreed formula. Both the CCTB and CCCTB require a definition of the

common tax base, which according to our interpretation of the legislation is defined as

follows: a 12.5 percent straight line depreciation rate for machinery (8 years), a 4 percent

rate for industrial buildings (25 years), a 6.67 percent rate for intangibles (15 years) and

an average value for inventories (alternative tax bases are also simulated as part of the

sensitivity analysis).

Debt and equity financing can be seen as imperfect substitute forms of capital use, and

their different tax treatment introduces an obvious distortion in the way firms and

investors choose to invest funds – the so-called debt bias. The main proposals to correct

for this tax-induced debt bias are, first, the comprehensive business income tax (CBIT),

which fully disallows the deductibility of interest, and so taxes all returns to investment

including the "normal" return. Second, an allowance for corporate capital (ACC)

provides an imputed return to investment, regardless of its form (debt or equity). Third,

an allowance for corporate equity (ACE/AGI, undistinguished in the model) keeps the

deductibility of interest (like in the traditional corporate tax design), but adds a

deductible imputed return for equity investments. All these are introduced by changing

how the corporate tax base is calculated. The change in tax liability has implications for

the cost of capital, and hence for investment decisions.

1.4.4 Sensitivity of model results and likely robustness to changes in the underlying

assumptions and/or data input

Extensive sensitivity analysis has been conducted around the core policy simulations.

These simulations provide additional insights into the consequences of altering the model

assumptions or policy choices, and offer a strong test of the robustness of the results. The

eight types of sensitivity analysis are as follows: (i) implementing the common corporate

(CCTB and CCCTB) for all firms, rather than just multinationals, (ii) alternative

definitions of the common tax base, (iii) stricter control on profit shifting, (iv) alternative

choices for capital-labour substitutability, (v) less compliance cost saving from

consolidation, (vi) compensate revenue with labour taxes, instead of changing transfer

payments, (vii) discrete location choice for firms, (viii) inclusion of a cross-border loss

offset provision with the common corporate tax base (CCTB), (ix) alternative

deductibility shares and rates for the ACE/AGI, and (x) alternative assumptions on the

ex-ante CIT rate closure.

The sensitivity analysis provides a more rounded picture of the model. Where different

model assumptions are simulated (such as alternative capital-labour substitutability or

less compliance cost savings), some changes in the magnitude of the effects are observed,

though the broad conclusions remain. For all core and sensitivity simulations full

country-level results are provided, as are additional tables as necessary to explain the

results.

2. E

FFECTS OF FUNDAMENTAL TAX REFORMS ON EFFECTIVE TAXATION

2.1. Brief Description of the Model

112

kom (2016) 0685 - Ingen titel

Corporate tax systems in Europe usually encourage the use of debt rather than equity

financing as interest payments are deductible for tax purposes while equity returns are

not. This unequal treatment might cause economic problems, such as excessive leverage

in the corporate sector and an associated increased vulnerability to economic crises. The

report focuses on the current extent of the corporate debt bias in the tax systems of the

EU-28 Member States and informs about whether different reform options could in

principle manage to address the debt bias and promote investment, possibly in a revenue

neutral way.

The report analyses current interest deduction limitation rules, intended to prevent an

excessive use of debt financing, and assess the impact of interest deductions limitations

rules on effective tax burdens in the EU-28 Member States. The main focus of the study

is the analysis of the consequences of four fundamental tax reforms which try to

overcome the debt bias differently, i.e. the Comprehensive Business Income Tax (CBIT),

Allowance for Corporate Equity (ACE), Allowance for Corporate Capital (ACC), Cost of

capital Allowance (CoCA).

The study relies on the general framework of the Devereux/Griffith model which

provides different indicators of the effective tax burden levied on corporate investments.

The Devereux/Griffith model allows considering marginal and profitable investments and

different financing sources taking into account the taxes borne at the corporate level and

the level of the shareholders. For marginal investments, the model provides the cost of

capital and the effective marginal tax rate (EMTR) as a measure of effective taxation.

The cost of capital represents the minimum pre-tax rate of return required for a real

investment to achieve the same after-tax return as a safe investment in the capital market

and should, from a theoretical point of view, impact on the scale of investments. For

profitable investments, the effective average tax rate (EATR) is a more proper measure

of the effective tax burden levied on the investment return and is used to identify the

effect of taxation on discrete location choices.

The fundamental reform options will impact the tax bases at corporate and shareholder

level differently and, therefore, will affect Member States tax revenues. Member States

might be reluctant to suffer revenue losses or increase their statutory tax rates as this is

associated with lower investment rates and growth. The report provides options for a

revenue neutral introduction of the fundamental tax reforms as well as possible

consequences for the level of investment in the EU-28 Member States.

2.2.

Model validation and peer review

The Devereux and Griffith methodology has acquired a strong reputation among

corporate tax experts. This approach is rooted in the model originally proposed by King

and Fullerton (1984) and as such has the advantage of allowing the computation of both

effective marginal tax rate and effective average tax rate under a unique framework.

The EMTR method has been extensively used to compute the effective tax rates levied

on capital income from different domestic investment over time and across countries.

However, as Devereux and Griffith (1998) demonstrate, this indicator may not be a

suitable one when the purpose of the analysis is the international location of capital. In

these circumstances, firms usually face a choice between two or more mutually exclusive

investment projects that are expected to earn some economic rent. The location choice

will be made on the basis of the highest post-tax economic rent, that is to say, where the

113

kom (2016) 0685 - Ingen titel

proportion of total income taken in taxes is the lowest. The most suitable measure for a

highly profitable multinational to adopt when deciding where to invest is the EATR, that

is, the present value of the expected total tax burden in relation to total profits. The

EATR is usually higher than the EMTR. The reason is that many tax deductions apply to

the cost of investment projects (which for the marginal investment project are equal to

the rate of return) but are irrelevant for economic rent. Once the strategic location choice

has been made, the cost of capital and the EMTR play an important role in determining

the optimal scale of the investment.

A range of studies have examined the theoretical foundation of the Devereux/ Griffith

model and its scope of application (Lammers 2002; Schreiber et al. 2002; Devereux and

Griffith, 2003). These forward-looking indicators permit to compare international tax

regimes and to isolate the structure of incentives and disincentives given by the different

tax systems to undertake a specific investment. Hence, these indicators are a useful

policy tools in the analysis of the effects of corporate tax differentials on resource

allocation.

The Devereux/Griffith approach was previously used in an Impact Assessment by the

European Commission (EEC 2001), following the advice of a panel of academic experts,

to comply with the mandate of the ECOFIN Council in December 1998 concerning the

scope of the analysis of effective tax rates.

114

Since then the methodology has been

applied for the calculation of effective tax rates in the EU and other countries on a yearly

basis.

2.3.

Underlying assumptions and data input

2.3.1.

Baseline and key assumptions

To gain insights on the effects of different reform options on effective tax rates, the cost

of capital and the EATR of the reform scenario are compared to the pre-reform scenario

(status quo). The results for the effective tax rates for the year 2015 are used as the status

quo scenario.

The basic approach proposed by Devereux and Griffith is to consider hypothetical

incremental investment located in a specific country undertaken by a company resident

possibly in the same country, but also possibly in another country. The hypothetical

investment takes place in one period and generates a return in the next period. The

impact of taxation is analysed by considering a number of features of the tax system,

including the statutory tax rate, capital allowances, depreciation rules and the treatment

of different financing sources, the treatment of foreign source income, wealth taxes paid

by the company, as well as possibly the treatment at the corporate and personal level of

dividends paid by the company, and wealth and capital gains taxes.

115

The tax database

comprises all relevant tax parameters for the EU-28 Member States.

Both the cost of capital and the EATR are computed for five different types of assets

(intangibles, buildings, machinery, financial assets, inventory), three different sources of

114

It is assumed that the tax system remains unchanged over the life of the investment.

114

kom (2016) 0685 - Ingen titel

financing (retained earnings, new equity, debt) and by three types of shareholders (zero-

rate, top-rate non-qualified and top-rate qualified) and can thereby be used to compare

the relative distortions introduced by the tax system in relation to certain investments or

financing sources both at the corporate level and shareholder level.

In presenting averages over different forms of assets, these assets are weighted equally,

while unequal weights are used for financing: retained earnings 55%, new equity 10%,

and debt 35% (OECD, 1991). As for true economic depreciation rates it is assumed in all

countries: intangibles (15.35%), industrial buildings (3.1%); machinery (17.5%),

financial assets (0%), and inventories (0%).

The alternative form of investment is assumed to be lending and the alternative

investments earns a real interest rate of 5%. The inflation rate is assumed to be 2% in all

countries. The computations of EATRs are based on a pre-tax rate of profitability of 20%

which corresponds to the standard economic assumption.

2.3.2.

Construction of the core policy impact assessment

The report provides calculation of effective tax rates using the Devereux/Griffith model

for Member States with interest deduction limitation rules by assuming binding limits to

the deductibility of interest costs.

Thin capitalization or earnings stripping rules limit the deductibility of interest costs in

case of debt financing and can be found in more and more Member States. The

Devereux/Griffith model does not allow a detailed implementation of interest deduction

limitation rules. In previous reports on effective taxation in the European Union, it has

always been assumed that interest costs were deductible irrespective of the existence of

limitation rules. For the purpose of this study, it is assumed that the limitations with

regard to interest costs are applicable. In Member States with interest deduction

limitation rules, this will result in a complete non-deductibility of interest costs at the

corporate level. The chosen approach (applicable vs. non-applicable) will neglect

substantial differences in the existing interest limitation deduction rules of the Member

States at the corporate level, like a possible carry-forward of non-deductible interest.

Therefore, the report will interpret the results cautiously.

Moreover, for the analysis of fundamental tax reforms, the tax codes of Belgium and

Italy are modified. Both Member States have already implemented one type of

fundamental tax reform: the Allowance for Corporate Equity. For the analysis of the

other hypothetical fundamental tax reforms, it is consistent to assume that no other

fundamental tax reform is currently in place. Otherwise, the effects of two fundamental

tax reforms (e.g. CBIT and ACE) would overlap and might even contradict and

compensate each other.

2.3.3.

Sensitivity of model results and likely robustness to changes in the

underlying assumptions and/or data input

The effect of the revenue neutral fundamental tax reforms on the EATR might differ if

the pre-tax rate of profitability is changed. Therefore, a sensitivity analysis with pre-tax

rates of profitability below and above the base case assumption of 20% is conducted. The

sensitivity of the effective tax measures to the assumed inflation and interest rates are

discussed in ZEW (2016b).

HE IMPACT OF TAX PLANNING ON FORWARD

LOOKING EFFECTIVE TAX RATES

3.1.

Brief description of the model

Multinationals companies have the opportunity to apply profit shifting strategies to

reduce their tax payments in high-tax countries and minimize the overall effective tax

burden on their global profits. The tax planning strategies of multinational corporations

have been a key issue on the international policy agenda for some years now. The aim of

the report is to explore the implications of typical tax planning strategies on effective tax

rates for cross-border investments between the 28 EU member states and the US.

The report derives forward-looking average and marginal effective tax rates that

incorporate the possibility of sophisticated tax planning strategies by multinationals and

the existence of preferential tax regimes such as IP boxes. Profit shifting channels from

high-tax to low-tax countries cover intra-group debt shifting, royalty payments, as well as

transfer pricing of goods and services. A number of cases are considered, including

“triangular” structures involving the use of tax haven finance affiliates and the use of

hybrid entities and hybrid instruments. The report also provides insights on the potential

impact of anti-avoidance measures against so-called aggressive tax planning.

As in the annually updated report on effective tax rates conducted by ZEW, the study at

hand applies the Devereux/Griffith model to calculate cost of capital (CoC) and effective

average tax rates (EATR). This allows one to compare the results for different tax

planning structures to the results for direct cross-border investments known from the

annual updates.

2003). OECD (2007) provides specific considerations on cross-border METR/AETR

analysis with triangular financing structure. The issue of incorporating IP Box regimes

into a model of effective tax rates was addressed in Evers et al. (2015).

Underlying assumptions and data input

3.3.1.

Baseline and key assumptions

The basic framework underlying the Devereux/Griffith model for cross-border settings

with a parent company and its subsidiary located in different countries have been

established in several earlier studies undertaken by ZEW on behalf of the European

Commission. The focus here is on multinational corporations hence the case of

incorporated SMEs and partnerships is ignored. Given to the high mobility on the

international capital market, personal taxes are of little importance for decision making in

multinational enterprises. Therefore, the analysis is limited to the corporate level (i.e.

excluding shareholders' taxation).
