EU Unshell Directive (informally “ATAD 3”) — Anti-Shell Company Directive

The EU Unshell Directive (informally called “ATAD 3”) is a European Commission directive proposal from 22 December 2021 (COM(2021)565) that would introduce minimum substance requirements for EU-resident companies. The proposal amends Directive 2011/16/EU (DAC — Directive on Administrative Cooperation), not the ATAD Directive 2016/1164. Its aim is to combat tax avoidance through substance-less shell companies within the EU that are established primarily to obtain tax advantages without conducting genuine economic activities.

• Three-step gateway test to identify at-risk companies (risk indicator)
• Minimum substance standards: own premises, at least one director resident in the member state or qualified local personnel, at least one own active EU bank account
• Tax consequences for failure to demonstrate substance: denial of treaty benefits and tax exemptions
• Reporting obligation via harmonised form to national tax authority
• Automatic exchange of information between EU member states

The European Commission published the Unshell Directive proposal (COM(2021)565) on 22 December 2021. The proposal was introduced under procedure reference 2021/0434(CNS) on the legal basis of Article 115 TFEU, which requires unanimity in the Council. It was a response to revelations from the Panama Papers, Pandora Papers, and other leaks exposing the misuse of shell companies within the EU. The proposal amends Directive 2011/16/EU (DAC) and complements existing transparency and substance requirements.

The European Parliament adopted its position on 17 January 2023 under rapporteur Lidia Pereira (EPP) (T9-0004/2023), supporting the Commission proposal with amendments. Negotiations in the EU Council proceeded slowly. Several member states, notably Luxembourg, Malta, Cyprus, and the Netherlands, raised significant concerns. The unanimity requirement under Art. 115 TFEU further complicates reaching agreement. On 8 July 2024, the Commission published a response to the EP position (SP(2024)270).

As of 2025, the directive has not been adopted. The Commission proposed the BEFIT package (Business in Europe: Framework for Income Taxation, COM(2023)532) and the HOT directive (Head Office Tax, COM(2023)528) on 12 September 2023. Whether elements of the Unshell proposal will be integrated into these initiatives or the proposal will continue as a standalone initiative remains open.

The Unshell proposal would apply to EU companies meeting all three gateway criteria in two consecutive tax years:

• More than 75% of revenues consist of passive income (in particular interest, dividends, royalties, capital gains on financial assets, real estate income, and other passive financial income — the list is non-exhaustive)
• More than 60% of the book value of the company’s assets is located outside the member state, or more than 60% of relevant income flows through cross-border transactions
• In the preceding two tax years, the administration of day-to-day operations and decision-making on significant functions has been outsourced to external service providers

Exclusions: listed companies, regulated financial undertakings, holding companies with holding activities in the same member state and at least 5 full-time equivalent employees exclusively carrying out those activities.

• Annual reporting obligation for companies meeting the gateway test
• Evidence of minimum substance standards: own office space or exclusive use thereof, at least one director resident in the member state or sufficient qualified personnel, at least one own active EU bank account
• Rebuttable presumption: companies failing substance test deemed shell entities
• Consequences: denial of treaty benefits, no tax exemptions, look-through treatment
• Automatic exchange of information: annual transmission of reporting data to all other EU member states
• Penalties: at least 5% of turnover for non-reporting or false reporting

3 corrections:
- last_amended date 2022-01-17 is misleading for a never-adopted proposal
- Official Journal publication date wrong — January 17, 2022 was not OJ publication
- ATAD 3 is not an official designation — Directive amends DAC (2011/16), not ATAD
3 updates:
- Commission response to EP position (July 2024) not mentioned
- Status 'proposed' could be more precise — 'awaiting Council decision' would be more accurate
- Key milestones missing in key_dates: EP committee and plenary votes
