Tax Administration EU Summit (TADEUS) took place in Dublin

The event brought together the Heads of Tax Administrations and the European Commission to strengthen administrative cooperation and support the effective implementation of EU tax policy priorities. 

The summit provided a forum for strategic discussion, exchange of experience and practical cooperation on common challenges facing tax administrations across the European Union. The 2026 summit focused on preparing for the effective implementation of several pieces of Union legislation, improving Member States’ agility to tackle VAT fraud, and closing tax gaps more effectively through data-driven and collaborative actions. Participants also discussed operational approaches to combat VAT e-commerce fraud, building on project outcomes and launching joint risk analysis initiatives.
