How the EU Tax Simplification Omnibus Proposal Could Transform Tax Planning

What’s Changing Under the Simplification Package

On 24 June 2026, the European Commission proposed a Tax Simplification Package consisting of two legislative proposals: the Direct Taxation Omnibus Directive and a Recast of the Directive on Administrative Cooperation (DAC). These aim to modernise direct tax rules, reduce reporting burdens, and make EU member states more competitive. (taxation-customs.ec.europa.eu)

Selected Highlights

• Abolition of withholding taxes on cross-border dividends, interest and royalties between EU companies.
• Extension of the Parent-Subsidiary Directive to include pension institutions.
• Introduction of full and immediate expensing for R&D-related tangible assets across all Member States.
• Streamlined interaction between CFC (Controlled Foreign Company) rules and Pillar Two, reducing overlap.
• Revisions to interest limitation provisions under ATAD to simplify and raise de minimis thresholds.
• DAC recast: consolidates nine existing DAC directives into a more coherent legal instrument, cuts reporting on certain cross-border arrangements by approx. 35%, saving around €7.9 billion/year EU-wide. (taxation-customs.ec.europa.eu)

Implications for Tax Planning

1. Cash flow benefits & investment incentives: Immediate expensing for R&D assets boosts investment attractiveness and enhances return calculations. Plan CapEx schedules accordingly.
2. Dividend and interest distribution strategies will change: no more withholding between EU companies—this alters optimal funding and dividend flow structures.
3. Interaction with CFC and Pillar Two: If your structure includes low-taxed subsidiaries, the proposed Omnibus changes may reduce the risk of overlapping compliance obligations or double “minimum taxes.”
4. Planning DAC obligations: With reduced reporting requirements, certain cross-border arrangements that offered limited information-value may be de-prioritised or phased out.

Practical Guidance & Adaptation Steps

• Conduct an internal review of your cross-border holdings: identify where withholding taxes currently apply and how their removal will affect your cashflows.
• Revise financial models to incorporate immediate expensing of R&D and assess whether past capital allocations need adjustment.
• Map current CFC exposure and Pillar Two top-up tax risk to optimize structure for overlapping rules.
• Re-evaluate your cross-border arrangements to ensure only those with substantial impact are maintained, given elimination of low-value reporting.

Example Scenario

A tech firm with subsidiaries in Germany, Ireland, and Cyprus, investing heavily in R&D assets. Under the Omnibus proposals:

• They can immediately expense their capital equipment in Ireland if qualifying.
• Dividends from the German entity to the Irish entity would flow without withholding.
• Their Cyprus unit may no longer need to report certain cross-border arrangements under DAC that prove low-value or information-poor.

Takeaway: These proposals, once enacted, shift the focus to efficiency, clarity, and investment-friendly structures. Companies should start scenario-planning now to take full advantage when the new rules arrive.
