Why Entity Setup Matters Now
Recent EU directives, especially Directive (EU) 2022/2523 (Pillar Two) and DAC9, have introduced top-up tax requirements and streamlined reporting rules. DAC9, adopted in April 2025, complements Pillar Two by enabling a centralised framework for the exchange of top-up tax information return, meaning that a multinational enterprise group may only have to file once at the group level instead of separately in each Member State. (taxation-customs.ec.europa.eu) However, Member States must have implemented DAC9 by 31 December 2025. The first group filings started 30 June 2026. (taxation-customs.ec.europa.eu)
To design an EU entity setup that is compliant and efficient, businesses must take into account:
- Choosing a jurisdiction with clear Pillar Two implementation and DAC9 reporting capabilities.
- Structuring entities so that they align with Group filing under DAC9 to avoid duplicate or redundant filings.
- Understanding local rules for corporate tax, withholding, and top-up tax where the effective tax falls under 15%.
Key Elements to Plan For
| Element | What to Check | Potential Pitfall | Best Practice |
|---|---|---|---|
| Entity jurisdiction | Do local laws fully implement Pillar Two, including Qualified Income Inclusion Rules (QIIR) and Qualified Domestic Minimum Top-up Tax (QDMTT)? | Partial or delayed implementation may expose to top-up or withholding risk. | Select countries with well-established Pillar Two jurisprudence or guidance, eg, Netherlands, Luxembourg. |
| Filing structure | Can group-level entities serve as Designated Filing Entities? Is there an interoperable DAC9 system in place? (taxation-customs.ec.europa.eu) | Separate filings at each entity may expose to errors or misalignment. | Build the group entity’s capacity to act as filing entity; centralise tax data systems. |
| Transfer pricing & APAs | Are you needing Advance Pricing Agreements? Is your income taxed adequately in source and destination states? | Aggressive attribution or mis-licensing of IP can lead to audit or exclusion from reliefs. | Use formal APAs and maintain substance. |
| Withholding & double tax treaties | Check treaties to ensure proper rate on outgoing interest, dividends, royalties under new EU rules. | Treaty shopping or improper payments may trigger STTR or subject-to-tax rule. | Document economic activity; map treaty obligations. |
Examples
- A holding company headquartered in an EU Member State: may file one top-up tax return under DAC9, but if constituent entities are in low-tax jurisdictions without Pillar Two, the group will need to pay the difference at the group level to reach 15%.
- A subsidiary taking in payments (interest, royalties) from other group companies: ensure the destination country’s withholding is acceptable under STTR and/or subject-to-tax rule to avoid surprise tax exposure.
Actionable Steps Right Now
- Run a compliance audit: Evaluate each planned entity’s tax rate vs 15% and look for treaty inconsistency.
- Select central filing entity early, ensure your group can capture financial information necessary for DAC9/GIR filing.
- Document substance: Personnel, premises, decision-making must match tax rights.
- Involve local counsel and tax advisers to map implementation differences; Pillar Two and DAC9 transposition dates may vary.
- Monitor updates: For example, the European Commission in its 2026 Annual Report on Taxation shows many member states introduced reforms in their tax systems, including incentives under the Clean Industrial Deal. (taxation-customs.ec.europa.eu)
Conclusion
Entity setup in the EU is no longer just about corporate tax rates. With DAC9 and Pillar Two now in force with real filing obligations—as of mid-2026—structuring for efficient compliance and sound documentation is essential. Choose jurisdictions with clarity, consolidate filings where possible, and maintain substance to avoid risk.
