Briefing - Taxation omnibus - 10-07-2026
As part of ongoing European Union (EU) efforts to create a more business-friendly and competitive environment, on 24 June 2026 the European Commission presented a proposal for a tax simplification package, including an omnibus simplifying EU rules on direct taxation. The proposed omnibus comprises a set of measures designed to streamline EU direct taxation rules and reduce administrative burdens, by revising key corporate tax directives. The legislative acts proposed for revision are the Interest and Royalties Directive, the Tax Merger Directive, Parent-Subsidiary Directive, the Anti-Tax-Avoidance Directive, the Tax Dispute Resolution Mechanisms Directive, and the Faster and Safer Relief of Excess Withholding Taxes Directive. The implementation of this legislation has led to a fragmented landscape across EU Member States, characterised by different rules and interpretations. Evidence indicates that these directives have created significant challenges for taxpayers and businesses, leading to legal uncertainty and inefficiencies, particularly for cross-border activities, which can undermine the proper functioning of the EU single market and business competitiveness. Additionally, the tax landscape has evolved significantly, both within the EU and globally, since the adoption of the directives the omnibus addresses. This evolution is particularly evident with the introduction of new regulations such as the EU's Global Minimum Tax Directive, which has created additional complexities in the existing tax framework. This implementation appraisal focuses primarily on the revision of the directives under the omnibus. It also examines implementation reports, evaluations, and other evidence assessing the application of the directives under revision. It summarises the main features of the omnibus proposal and considers the European Parliament's perspective, written questions from its Members, and the views of stakeholders, including EU institutions and advisory bodies.
