What is the EU Tax Simplification Omnibus?
The European Commission on 24 June 2026 adopted a sweeping Tax Simplification Package which includes two legislative proposals: the Direct Taxation Omnibus and the Recast of the Directive on Administrative Cooperation (DAC). These aim to modernise EU direct tax rules, reduce administrative burden, and improve competitiveness across the Single Market. (taxation-customs.ec.europa.eu)
Key Measures and Impacts
- Abolition of withholding taxes on cross‐border payments (dividends, interest, royalties) between EU companies, unlocking cross‐border capital flow. (taxation-customs.ec.europa.eu)
- Extension of the Parent‐Subsidiary Directive to include pension institutions, enabling them to benefit from withholding tax exemptions on dividends. (taxation-customs.ec.europa.eu)
- Full and immediate expensing rules for R&D‐related tangible assets in all Member States to incentivise innovation. (taxation-customs.ec.europa.eu)
- Simplification in the ATAD interest limitation rules, including removing implementation options and increasing the mandatory de minimis threshold to ease compliance. (taxation-customs.ec.europa.eu)
- Streamlined DAC reporting obligations:
- Companies under the EU Minimum Tax / Pillar Two may be excluded from DAC6 reporting. (taxation-customs.ec.europa.eu)
- Removing hallmarks in DAC6 considered low value; refining just what must be disclosed. (taxation-customs.ec.europa.eu)
- Simplification for DAC7, via threshold adjustments (e.g. removing the activity threshold, increasing monetary threshold to ~€3,000) for platforms reporting income. (taxation-customs.ec.europa.eu)
- Harmonising notifications under DAC4 and DAC9, with one template and one deadline. (taxation-customs.ec.europa.eu)
- Improving data quality by verifying Tax Identification Numbers (TINs) centrally. (taxation-customs.ec.europa.eu)
What’s the Timeline?
These are proposals, not yet laws—they still require approval by the European Parliament and the Council. The changes are expected to take effect gradually, following those approvals. (taxation-customs.ec.europa.eu)
Implementation will likely lag across Member States, especially for measures needing domestic law changes (e.g. ATAD amendments), or technical infrastructure (DAC tools).
How Businesses Should Prepare Now
- Review existing cross‐border payment structures to anticipate where withholding tax changes could deliver savings.
- For pension funds, assess whether they fall under the revised Parent‐Subsidiary Directive scope, and what compliance steps will follow.
- Monitor national legislation related to ATAD interest limitation rules—estimated thresholds and allowed carve‐outs will matter.
- DAC reporting: categorize your arrangements under DAC6/DAC7 now to see whether they may be excluded or simplified under the new rules.
- Ensure systems are in place to capture correct TINs, country‐by‐country and top‐up reporting (DAC9), and country‐by‐country reporting (DAC4).
Practical Example
An EU tech company based in Ireland that currently pays withholding tax on royalty payments to a parent company in Germany may see those payments become tax‐free once the Omnibus rules abolish withholding taxes among EU members.
Watch Out For
- Final thresholds under DAC7 and DAC6 may differ from proposal—keep up with legislative texts.
- Member States may resist loss of revenue from withholding taxes and could delay implementing changes.
- Pillar Two interactions—CFC rules standardization aims to reduce overlap, but detailed guidance will be needed to avoid double compliance.
Bottom line: If you operate across borders inside the EU—particularly in digital services, R&D, or cross‐border payments—this Omnibus could reshape your planning. Prepare now, follow the legislative process, adjust systems, and consider where simplifications will fall in your favour.
