EU Tax Simplification Package 2026: Planning Opportunities Under Withholding Tax and R&D Reforms

Overview of the Simplification Package

In June 2026, the European Commission adopted proposals collectively known as the Tax Simplification Package, including the Direct Taxation Omnibus Directive and the DAC Recast Directive. These aim to reduce compliance costs by approximately €7.9 billion annually, including €3.3 billion in reduced administrative costs. (taxation-customs.ec.europa.eu)

Key tax planning-relevant features include:

• Abolition of withholding taxes on cross-border EU payments of dividends, interest, and royalties between EU companies under certain conditions.
• Extension of the Parent-Subsidiary Directive to include pension institutions for withholding tax exemption on dividends.
• A common minimum standard for investments in R&D-related tangible assets: full, immediate expensing across all Member States.
• Interest limitation rules under ATAD are being simplified by removing optional implementation paths and increasing the de minimis threshold. (taxation-customs.ec.europa.eu)

Planning Opportunities for Multinationals & Domestic Players

1. Assessing Structures Involving Withholding Taxes

   • If your company pays interest, dividends or royalties within the EU, check whether the proposed abolition applies in your structure. Restructuring may allow avoiding withholding taxes once the Directive is enacted.
   • Pension funds can be included under the withholding exemptions—consider partner arrangements or holding structures to take advantage.

2. R&D Investment Timing

   • For companies planning capital investment in R&D-intensive equipment (e.g. manufacturing assets, labs), full immediate expensing means the entire cost can be deducted in the year of purchase—improving cash flow and project viability.
   • Ensure that assets qualify under “R&D-related tangible assets” criteria: capital goods, equipment, prototypes linked to R&D, etc.

3. Interest Limitation Rules Review

   • Revisit your financing arrangements, especially if you currently rely on implementation options. The new rules reduce optionality, so some reliefs may disappear.
   • The increased de minimis threshold means small-scale financing arrangements may escape strict limitation—check if your structure can benefit.

Sample Planning Case

Manufacturer with EU Subsidiaries: A German parent owns subsidiaries in Portugal, Austria, and Estonia. The Spanish subsidiary (or Portugal) charges interest on a financing loan to the Austrian unit. Under current rules, withholding tax might apply; under the proposed simplification, once adopted, this could be fully exempt.

Simultaneously, if the company invests in lab facilities in Austria for new product R&D, full immediate expensing means the full cost could be written off immediately rather than over time—significantly improving net present value of projects.

Risks & Implementation Timeline

• These are proposals, not yet fully enacted. Transposition periods will apply.
• Differing domestic qualification rules for R&D assets may still exist—check whether definitions under national law align with EU standard.
• The DAC Recast also removes some reporting obligations—review your compliance commitments under DAC6, DAC7, and interaction with Pillar Two.

What to Do Now

• Map your intra-EU payment streams for dividends, interest, royalties—identify where withholding taxes are currently imposed.
• Model R&D project costs and timing to see gains under full expensing.
• Track domestic law changes: once proposals are adopted by Council and Parliament, Member States will need to transpose.
• Consult tax policy advisers in key jurisdictions to verify alignment and local implementation nuances.

Conclusion: The Tax Simplification Package presents significant tax planning opportunities—especially for companies with cross-border investments and R&D activities. Early preparation can capture long-term cash flow and efficiency gains.
