Entity Setup in the EU: Using Pillar 2, ATAD, and Withholding Changes to Structure Efficiently

Core EU Rules That Shape Entity Setup

• ATAD (Anti-Tax Avoidance Directive) rules: minimum standards covering interest limitation, exit taxation, controlled foreign corporations, hybrid mismatches. These remain binding since implementation deadlines (e.g. Hybrid Mismatch Rule fully in force from 1 Jan 2022) and influence entity choice. (taxation-customs.ec.europa.eu)
• Pillar 2: Entities in large multinational groups with ≧ €750 million revenue are subject to global minimum taxation; effective tax rates <15% in a jurisdiction lead to top-up taxes via Income Inclusion or Undertaxed Profits Rules. (taxation-customs.ec.europa.eu)
• Withholding tax changes under the Omnibus proposal: abolition of cross-border withholding taxes on dividends, interest, royalties between EU companies could reduce complexity and costs of financial flows. (taxation-customs.ec.europa.eu)

Structuring Strategies Under Emerging Rules

• Centralize EU entity jurisdictions: Use jurisdictions with strong IIR domestic implementation and clarity on Pillar 2 transposition to host central functions. This helps with compliance under DAC and Pillar 2.
• Avoid substance pitfalls: With Pillar 2’s carve-outs (5% tangible asset, 5% payroll), simply being a shell entity without people/employees/assets is risky and offers little benefit. Substance matters more than ever. (taxation-customs.ec.europa.eu)
• Optimize financing and royalty flows: Once withholding taxes between EU firms are abolished, previously higher-taxed structures for internal financing or IP licensing may become more efficient. Look for reorganizing so passive income resides in EU entities.

Considerations for ATAD Compliance

• Hybrid mismatch rules: When setting up cross-border entities, avoid structures that create mismatch in tax treatment under national laws; EU rules mandate elimination of double deductions, mismatched timings. (taxation-customs.ec.europa.eu)
• Exit taxation and controlled foreign corporations: Moving assets or profit centers must be evaluated under ATAD exit-tax rules or CFC rules; certain jurisdictions may impose deferred tax or immediate inclusion of profits.

Example Structure Scenarios

• Scenario A: A SaaS company with operations in Germany, Italy, and Poland, earning IP-based royalties. Under future withholding tax abolition, move their royalty flows through an EU entity rather than a non-EU holding, reducing friction and perhaps taxation. Ensure substance with employees and tangible assets in that entity to comply with Pillar 2.
• Scenario B: A manufacturing group uses a subsidiary in Estonia for passive income collection. Given Pillar 2, they must verify that local effective tax rate (after carve-outs) isn't falling below 15%. If yes, top-up tax applies, so structuring for IIR or QDMTT is essential.

Actionable Steps for Those Considering Formation or Reorganization

1. Select jurisdiction based on Pillar 2 implementation track record—time to enact top-up, digital infrastructure, treaty network.
2. Ensure substance now—office, staff, tangible assets, active operations will help under ATAD and Pillar 2.
3. Map future passive income flows—royalties, dividends, interest—and anticipate how withholding tax changes may affect them.
4. Review group’s reporting obligations—set systems for GIR (Global Information Return), ensure readiness for TTIR under DAC9.
5. Use advisors familiar with both domestic implementation and cross-border effects to avoid unwelcome surprises.

Conclusion

Recent EU policy changes are tilting the playing field. With Pillar 2 firmly in force, ATAD still relevant, and proposals to remove withholding taxes within the EU, entity setup strategies need updating. Well-designed structures with substance, clear compliance systems, and foresight can yield efficiency and tax risk mitigation in this evolving landscape.
