Overview
In June 2026, the European Commission unveiled a Tax Simplification Package that includes the Direct Taxation Omnibus Directive and a Recast of the Directive on Administrative Cooperation (DAC Recast). These proposals are designed to simplify the EU’s direct tax rules, reduce compliance burdens, and make the Single Market more competitive.(taxation-customs.ec.europa.eu)
Key Changes & Their Implications
| Measure | What’s Changing | Why It Matters | What Businesses Should Do Now |
|---|---|---|---|
| Abolition of withholding taxes on cross-border payments of dividends, interest & royalties between EU companies | Eliminates inter-company WHT that has long been a barrier to cross-border investment. Also extends Parent-Subsidiary Directive benefits to pension institutions.(taxation-customs.ec.europa.eu) | Frees up cash flow, simplifies accounting, and makes intra-EU investments more attractive. Investment returns currently trapped by complex reclaim systems. | Audit existing cross-border finance flows. If your group uses WHT exemptions or reclaim claims, map all past cases and pending ones. Be ready to adapt treasury functions. |
| Full expensing of R&D-related tangible assets via a common minimum tax standard | Upfront deductions enabled in all Member States for investments in eligible R&D tangible assets.(taxation-customs.ec.europa.eu) | Changes investment calculus—accelerated depreciation incentivises capital investment in tech, labs, and manufacturing facilities. | Companies with R&D physically anchored in the EU should accelerate capex before rules take effect. Engage with local tax authorities to understand eligibility and claiming mechanisms. |
| DAC Recast (Administrative Cooperation overhaul) | Consolidates nine DAC directives into one, eliminates redundant reporting, raises thresholds for DAC7 (platform-based income), improves TIN (Tax Identification Number) verification, and centralises notifications for country-by-country (CbC) reporting and top-up tax reporting under DAC9.(taxation-customs.ec.europa.eu) | Less paperwork, more clarity, fewer overlapping obligations—especially for digital platforms and large multinationals. | Review current compliance workflow for DAC6-7-9 obligations. Track deadline & threshold changes; ensure systems capture TINs correctly. |
| Modernizing ATAD interest limitation & harmonizing CFC rules with Pillar 2 | Reduces optionality among Member States in ATAD implementation, introduces higher de minimis thresholds, and seeks consistency between Controlled Foreign Company rules and the global minimum tax regime (Pillar 2).(taxation-customs.ec.europa.eu) | Harmonization lowers tax arbitrage risk, improves predictability. Firms operating across countries with varying ATAD regimes will face fewer conflicts or surprises. | Map your group’s exposure to ATAD. Include intra-group debt and interest expense structure. If your operations span jurisdictions with divergent CFC rules, plan for higher subtotals under Pillar 2. |
Effective Dates & Planning Horizon
The proposals are not yet enacted—they are still in consultation and legislative stages. Typically, EU Directives allow Member States time to transpose them into national law. Businesses should expect phased implementation over 2027-2029. It is not yet possible to rely on them as law. Engage with local counsel around implementation plans.
Case Study Example
A German tech company purchasing royalty licenses from an EU-based licensor currently pays withholding tax of 15% in the source country, followed by a complex reclaim process. Under the new Omnibus proposal, assuming both entities qualify, no WHT would apply—improving cash flow and reducing accounting & compliance costs by thousands of euro per year.
Actionable Insights
- Audit intercompany payment flows—identify relationships to which WHT or administrative burdens currently apply.
- Lobby & monitor national transposition of these proposals—Member States may add qualifiers or delays.
- Upgrade compliance tools—ensure systems can handle revised DAC reporting thresholds, TIN verification, and data centralisation.
- Coordinate tax, FP&A, and treasury functions—to take advantage of full expensing and other capital investment incentives.
Conclusion
The proposal marks a game changer for EU business taxation: reduced WHT, clearer DAC obligations, harmonized ATAD & Pillar 2 norms. Although not yet law, the package paves the way toward an integrated, simpler tax regime in the EU—offering significant opportunities for companies ready to adapt.
