What is the Tax Simplification Package?
On 24 June 2026, the European Commission proposed a sweeping package of reforms aimed at simplifying direct tax laws and EU administrative cooperation rules (DAC). Key objectives include reducing compliance burdens, removing unnecessary withholding taxes, and harmonizing rules around interest limitation, CFC regimes and cross-border restructuring. Estimated savings for businesses are approximately €7.9 billion per year. (taxation-customs.ec.europa.eu)
Key Proposals & Implications
| Reform Area | What’s Changed / Proposed | Why It Matters |
|---|---|---|
| Parent-Subsidiary Directive | Extended scope to include pension institutions, enabling withholding tax exemptions on dividends from subsidiaries in other Member States. | Aids pension fund cross-border investment, eases double taxation barriers. (taxation-customs.ec.europa.eu) |
| Withholding Taxes (Dividends, Interest, Royalties) | Abolishing most withholding taxes on cross-border payments between EU companies. | Reduces friction, improves capital flow and intra-EU investment. (taxation-customs.ec.europa.eu) |
| CFC Rules & Pillar Two Interaction | Streamlined interaction to reduce overlaps and legal uncertainty; harmonised model proposed. | Helps multinationals ensure compliance and reduce unexpected penalties. (taxation-customs.ec.europa.eu) |
| ATAD Interest Limitation | Raised mandatory de minimis thresholds, excluded low-risk debt and market-based financing, limiting complexity. | Simplifies rules, improves predictability for corporate debt financing. (taxation-customs.ec.europa.eu) |
How to Plan Your Entity or Investment Structure
- Map your cross-border flows: identify where dividends, interest, royalties are paid or received within EU group; use proposed changes to minimize withholding tax exposure.
- Review pension fund engagement: if acting as a pension institution, anticipate benefit under the expanded Parent-Subsidiary scope.
- Plan finance mechanisms: with revised interest limitation, assess whether external financing can be structured to qualify as low-risk or market-based, thereby escaping burdensome limits.
- Align with Pillar Two: ensure your CFC and minimum tax models don’t inadvertently trigger top-up tax or UTPR liabilities due to overlaps or inconsistent definitions.
Case Example
Imagine a Luxembourg-based R&D-focused group with subsidiaries in Spain and France, and a UK-based pension institution participating in dividend income. With the proposed rules:
- Dividends to the pension institution could be exemption-eligible under expanded Parent-Subsidiary Directive.
- Intercompany interest or royalties payments become simpler due to abolished withholding tax between EU companies.
- Cross-border R&D investments could use full and immediate expensing for qualifying tangible R&D-assets — improved capital deployment. (taxation-customs.ec.europa.eu)
Timelines & Risks
- These proposals are currently proposed, not yet final. They must pass through the European Parliament and Council before becoming binding rules. (taxation-customs.ec.europa.eu)
- National measures may lag implementation; transitional uncertainties exist.
- Keep monitoring for guidance on implementation with DAC recast and the Tax Simplification Omnibus.
Takeaway: By staying ahead of these proposals and aligning tax planning accordingly, companies operating across EU borders can remove longstanding frictions, reduce costs, and secure stronger tax certainty.
