EU tax legislation has long been criticised for layering complexity on complexity. Directives adopted at different points in time — the Parent-Subsidiary Directive, the Interest and Royalties Directive, the Anti-Tax Avoidance Directives, the successive iterations of DAC — each addressed a specific problem but created a framework that businesses, particularly those operating across multiple Member States, find difficult and expensive to navigate. The 2026 package is the most significant attempt to rationalise that framework since the Draghi report on competitiveness identified tax complexity as a structural drag on EU investment.
The headline measure in the Taxation Omnibus is the abolition of withholding taxes on cross-border dividend, interest, and royalty payments between EU companies. This has been a long-standing barrier to Single Market integration: companies moving capital across borders have faced a patchwork of national withholding regimes, treaty relief procedures, and intermediary requirements that add cost and delay. Removing that barrier — alongside an extension of the Parent-Subsidiary Directive's withholding exemptions to pension institutions — directly addresses a structural friction that the Savings and Investments Union strategy has made a priority.
Two further measures in the Omnibus are worth noting for businesses with cross-border operations. The streamlining of Controlled Foreign Company rules and their interaction with the Pillar Two global minimum tax framework removes a genuine source of double compliance for multinationals already subject to the 15% minimum rate. And the expansion of the Tax Merger Directive to cover all forms of corporate reorganisation under EU company law — mergers, divisions, and asset transfers — makes cross-border restructuring meaningfully simpler, removing a disincentive to the kind of consolidation European industry increasingly needs.
The DAC recast tackles a different but related problem: the accumulation of reporting obligations that have grown with each successive amendment since the original Directive on Administrative Cooperation was adopted in 2011. Nine directives are consolidated into a single instrument. Approximately 3,000 multinational groups already subject to Pillar Two are relieved of duplicative cross-border tax arrangement reporting, saving an estimated €300 million annually. The increase in reporting thresholds for online sales of goods removes obligations for over 10 million sellers — a significant measure for the digital economy and for the circular economy in particular, given the volume of private second-hand goods trading through digital platforms.
The Commission estimates total annual compliance cost savings across both proposals at €7.9 billion, of which €3.3 billion relates to administrative burden reduction. Set against the Commission's overall simplification target of €37.5 billion by the end of this mandate, the package brings cumulative savings to over €18 billion — approaching half the goal.
The procedural reality, however, is a constraint on optimism. Both proposals require unanimous approval by all 27 Member States in Council. Tax unanimity is structurally difficult: individual Member States can and do block proposals that threaten their national tax arrangements, and the history of EU direct tax legislation is littered with measures that spent years in negotiation before being substantially watered down or abandoned. The Common Consolidated Corporate Tax Base is the most cited example. The Commission's confidence in this package rests partly on framing it as simplification rather than harmonisation — a distinction that may carry political weight in Council, but is not a guarantee of smooth passage.
For businesses operating across the EU — in manufacturing, financial services, professional services, or the digital economy — the substantive measures in this package would, if adopted, reduce real costs and improve legal certainty. The target timeline for implementation is 2028 for most measures, with remaining provisions by 2030. Organisations with an interest in the outcome should monitor the Council working group process closely and be prepared to engage during the European Parliament consultation phase, where input on practical implementation details can still shape the final text.
