EU Anti-Tax Avoidance Framework
The EU anti-tax avoidance framework has developed rapidly since 2015, responding to the OECD Base Erosion and Profit Shifting (BEPS) project, public concern about corporate tax avoidance, and the need for coordinated action within the Single Market. The framework comprises the Anti-Tax Avoidance Directives (ATAD 1 and 2), Directive on Administrative Cooperation (DAC) provisions on automatic exchange of information, and the EU list of non-cooperative jurisdictions.
Anti-Tax Avoidance Directive (ATAD 1) — Directive 2016/1164
ATAD 1 (Council Directive (EU) 2016/1164) establishes legally binding anti-tax avoidance measures across all Member States. Adopted on 12 July 2016, it implements BEPS recommendations in EU law and goes beyond the minimum standards agreed at the OECD level. Member States were required to transpose ATAD 1 by 31 December 2018.
Interest Limitation Rule
Article 4 restricts the deductibility of exceeding borrowing costs (borrowing costs minus taxable interest revenues) to 30% of earnings before interest, tax, depreciation, and amortisation (EBITDA). Member States may apply a de minimis threshold of EUR 3 million and may exclude loans used to fund long-term public infrastructure projects.
The limitation addresses profit shifting through excessive debt financing. The Court of Justice in L V CL (Case C-650/20) confirmed that the interest limitation rule is compatible with the freedom of establishment, provided it does not discriminate between domestic and cross-border situations.
Exit Taxation
Article 5 requires Member States to impose an exit tax on assets transferred to a third country or on the transfer of tax residence where the assets remain within the taxing jurisdiction of the Member State. The exit tax is levied on the difference between the market value and the tax value of the transferred assets.
The exit tax provision reflects the Court’s judgment in National Grid Indus (Case C-371/10), which held that exit taxation is a proportionate restriction on the freedom of establishment where it permits deferred payment and immediate taxation is limited to cases where recovery is at risk.
General Anti-Abuse Rule (GAAR)
Article 6 requires Member States to introduce a GAAR disregarding arrangements that are not genuine or whose main purpose or one of the main purposes is obtaining a tax advantage that defeats the object or purpose of the applicable tax law. The GAAR applies to arrangements put in place for the essential purpose of obtaining a tax advantage, establishing a subjective test in addition to the objective test of artificiality.
Controlled Foreign Company (CFC) Rules
Article 7 requires Member States to attribute the undistributed income of a controlled foreign company (CFC) to its controlling taxpayer where the CFC is subject to an effective tax rate lower than 50% of the host Member State’s nominal rate. The CFC rules apply to entities in which the taxpayer holds a direct or indirect interest of more than 50% of voting rights, capital, or profit rights.
Article 7(2) provides an optional transactional approach: where the CFC’s effective tax rate is below the threshold, the Member State may attribute only the non-genuine income artificially diverted from the controlling entity.
ATAD 2 — Directive 2017/952
ATAD 2 (Council Directive (EU) 2017/952) addresses hybrid mismatches with third countries, supplementing ATAD 1 which addressed intra-EU hybrid mismatches. Hybrid mismatches arise from differences in the legal characterisation of entities, instruments, or permanent establishments between two jurisdictions, resulting in double deduction or deduction without inclusion.
ATAD 2 requires Member States to neutralise hybrid mismatches through rules that deny deductions or require income inclusion. The Directive extends to reverse hybrid entities (entities that are transparent in their jurisdiction but treated as opaque in the jurisdiction of their investors), ensuring that such arrangements do not result in untaxed income.
DAC 6 — Mandatory Disclosure Rules
Directive (EU) 2018/822 (DAC 6) imposes mandatory disclosure obligations on intermediaries and taxpayers in respect of reportable cross-border arrangements. The Directive entered into force on 25 June 2018, with reporting obligations applying to arrangements whose first step was implemented after 25 June 2018.
DAC 6 introduces the concept of “hallmarks” — categories of cross-border arrangements that present potential tax avoidance characteristics. Hallmarks include: arrangements involving confidentiality clauses; arrangements where the intermediary receives a fee contingent on the tax advantage; arrangements involving standardised documentation; arrangements involving losses, circular transactions, or deductible cross-border payments to low-tax jurisdictions.
Intermediaries must disclose reportable arrangements within 30 days to the competent tax authority, which automatically exchanges the information with all other Member States through the Central Directory. Failure to disclose attracts penalties that Member States must ensure are effective, proportionate, and dissuasive.
The Court of Justice in T v Belgium (Joined Cases C-694/20 and C-695/20) addressed the legal profession privilege under DAC 6, holding that Member States must exempt legal advice from mandatory disclosure where the intermediary is a lawyer and the information is subject to legal professional privilege.
Country-by-Country Reporting (CbCR)
Directive (EU) 2016/881 implements the OECD’s CbCR standards within EU law. Multinational enterprise groups with consolidated group revenue of at least EUR 750 million must report annually on their revenue, profit, taxes paid, capital, earnings, employees, and assets for each jurisdiction in which they operate. CbCR reports are exchanged automatically between Member States under the DAC framework.
Public CbCR was introduced by Directive (EU) 2021/2101, requiring multinational groups with total consolidated revenue exceeding EUR 750 million to publish their CbCR data. The public disclosure requirement applies from 2024 for groups with operations in the EU.
EU List of Non-Cooperative Jurisdictions
The EU list of non-cooperative jurisdictions (the “EU blacklist”) is a transparency and governance tool established by the Council in 2017. The list identifies third countries that fail to meet the EU’s criteria for tax good governance, including tax transparency, fair taxation, and implementation of BEPS minimum standards.
Listed jurisdictions face defensive measures: Member States may apply non-deductibility of payments, Controlled Foreign Company (CFC) rules, withholding taxes, and restrictions on participation exemption. The list is reviewed twice annually.
