The European Commission’s Trojan horse: How the Omnibus Tax Directive would put an end to tax sovereignty

As the European Commission pursues its objective of simplifying the EU tax framework through the proposed Tax Omnibus Directive, an important question emerges: does simplification necessarily lead to greater efficiency, or could it come at the expense of Member States' fiscal autonomy?

In this thought-provoking article, Tax Partner, Oliver R. Hoor, examines the proposed amendments to six key EU tax directives and assesses their broader implications for tax policy, competitiveness and national sovereignty. While the initiative is presented as a simplification exercise, the analysis argues that it could fundamentally reshape the balance of power between the European Commission and Member States.

The article provides a detailed overview of the proposed changes, explores their practical consequences for businesses and tax administrations, and offers a critical perspective on whether the Tax Omnibus Directive represents genuine regulatory simplification or a far-reaching shift in EU tax governance.
