## Overview of the 2026 Tax Simplification Package
On **24 June 2026**, the European Commission adopted a major tax simplification initiative comprising two key pieces: the **Omnibus on Direct Taxation** and a **recast of the Directive on Administrative Cooperation (DAC)**. These proposals aim to streamline and modernize the EU’s direct taxation framework, reducing regulatory complexity, cutting red tape, and promoting cross-border investment and competitiveness.

Financially, the package is expected to deliver ~**€7.9 billion** annually in savings, including ~**€3.25 billion** in administrative burden relief.

## Key Measures Relevant to Tax Planning & Pillar Two
Here are the most important features that taxpayers and tax advisers should watch:
| Measure | What It Does | Implication for Businesses / Tax Planning |
|---|---|---|
| **Abolition of withholding taxes** on cross-border dividends, interest, and royalties between EU companies | Removes a longstanding tax barrier under cross-border payments between companies within the EU | Enhances cash flow, simplifies structuring of investments or royalties flows between subsidiaries; reduces lobbying for double tax relief arrangements ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai)) |
| **Extension of Parent-Subsidiary Directive to pension institutions** | Pension funds would also benefit from withholding tax exemptions on dividends from other Member States | Could significantly lower the cost of investment portfolios managed by EU pension institutions; structuring opportunities for pension-fund-backed entities ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai)) |
| **Immediate expensing for R&D-related tangible assets across Member States** | Harmonises treatment of R&D capital expenditure so that businesses can claim full deduction immediately | Encourages investment in R&D infrastructure; helps especially SMEs and capital-intensive industries; affects ROI modelling ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai)) |
| **Streamlining CFC rules to align with Pillar Two (Global Minimum Tax)** | Removes overlapping requirements between Controlled Foreign Corporation (CFC) rules and Pillar Two; introduces harmonised model | Simplifies tax exposure calculations; reduces risk of double taxation; aids in consistent compliance across EU jurisdictions under Pillar Two framework ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai)) |
| **Modernised Interest Limitation Rule (ATAD-based)** | Raises mandatory de minimis; excludes low-risk third-party borrowing and market-based arrangements | Provides breathing space for corporate finance planning; more favourable treatment for debt financing under certain thresholds ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai)) |
## Compliance Impacts & Reporting Simplification (DAC Recast)
- Consolidates existing DAC directives (DAC1 through DAC8) into a single unified legal instrument for administrative cooperation. ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/taxation/tax-transparency-cooperation/administrative-co-operation-and-mutual-assistance/directive-administrative-cooperation-dac_en?utm_source=openai))
- **Reduces reporting obligations** for groups already under Pillar Two, removing duplicative requirements under DAC6. Estimated compliance volume reduction: ~35%, with savings of **€300-€700 million per year** depending on size and sector. ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai))
- Introduces a central notification obligation for country-by-country reporting and top-up tax declarations to avoid duplicative filings. Creates a unified template and harmonised deadlines. ([taxation-customs.ec.europa.eu](https://taxation-customs.ec.europa.eu/news/european-commission-proposes-landmark-tax-simplification-package-streamline-compliance-and-boost-2026-06-24_en?prefLang=fi&utm_source=openai))
## Actionable Tips for Businesses & Tax Advisors
1. **Review withholding tax flows now:** Identify intra-EU entities paying dividends, interest, or royalties—prepare for changes once Omnibus is adopted.
2. **Align accounting for R&D investments:** Capitalize on the shift toward immediate expensing; adjust financial projections and investment policies.
3. **Assess your CFC exposure under Pillar Two:** With harmonisation coming, entities should map cross-border activities, consider restructuring where overlapping burdens exist.
4. **Track DAC recast progress:** New reporting regimes will simplify DAC6, DAC4, DAC9 etc.—keep ahead of timelines and template changes.
5. **Engage with national tax authorities:** Because directives require transposition into Member State law, some flexibility or variation may occur—monitor how each Member State adopts these reforms.
## Example Scenarios
**Scenario A: A tech company headquartered in Germany with subsidiaries in Spain and Poland**
- Currently, paying royalties from Poland to Germany may trigger withholding tax under bilateral rules. Under the Omnibus, once withholding tax is abolished, flows become cleaner, cash flow improves, optimizing internal IP monetization.
- R&D facility in Poland building tangible assets—investment can be immediately deducted, reducing taxable profit in early years, improving ROI and WACC (weighted average cost of capital).
**Scenario B: An EU insurance group managing pension funds in France and Italy**
- As pension institutions gain exemption under the Parent-Subsidiary extension, dividends paid among pension entities cross-border are exempted from withholding tax—meaning greater net returns for beneficiaries.
## Timelines & Next Steps
- Proposals are **pending adoption** by European Parliament and Council. Once agreed, directives need **transposition** into national law by Member States.
- Changes under DAC recast and Omnibus will have **phased implementation**, especially regarding reporting deadlines and template standardisation.
- Businesses should engage with regulatory updates in late 2026 through 2028 to ensure compliance.
**Conclusion**: The Tax Simplification Package represents a substantial shift in the EU tax landscape—simplifying structures, reducing barriers, aligning with global minimum tax efforts—offering opportunities for well-prepared companies to streamline operations and reduce tax-compliance burdens.
