The Commission’s Trojan Horse: How the Tax Omnibus Directive would eliminate EU Tax Sovereignty

The European Commission's proposed Tax Omnibus Directive has been presented as a simplification initiative designed to enhance competitiveness and reduce administrative burdens across the EU. However, behind this objective lies a proposal that could fundamentally reshape the balance of power between the European Union and its Member States in the field of direct taxation.

In this article, Tax Partner, Oliver R. Hoor, examines the draft directive in detail, assessing its impact on six existing EU tax directives and exploring whether the proposed changes genuinely simplify the legislative framework or instead represent a significant step towards greater tax harmonisation. The analysis considers the implications for national tax sovereignty, taxpayer certainty, and the future of EU tax policymaking.
