Tax Administration EU Summit - TADEUS

TADEUS is a forum for the heads and deputy heads of Member States’ tax administrations. They meet regularly, together with the Commission, to improve administrative cooperation within the EU and to meet common challenges.

TADEUS Summit, Malaga, 21-22 November 2023

The Heads and Deputy Heads of tax administrations from all EU Member States met in Malaga on 21-22 November to discuss a number of important issues including:

  • recent and future developments in administrative cooperation between Member States in order to fight VAT and direct tax evasion and fraud
  • possible common methodologies for estimating various types of tax gaps
  • ways of increasing taxpayers’ trust and voluntary compliance at national, European and global level.

The full outcome statement of the meeting is available below.

TADEUS 2023 Heads outcome statement

How did the forum begin?

The forum originated in April 2018, when the EU economy and finance ministers agreed to foster cooperation between their tax administrations. Before that, a series of Commission reports on Member States’ administration of value added tax, income tax and the recovery of taxes had revealed deficiencies in the administrative cooperation within the EU.

In June 2018, the Heads of Tax Administration and the Commission decided - at a meeting in Thessaloniki - to create a forum called TADEUS, short for Tax Administration EU Summit. Since then, heads and deputy heads of Member States’ tax administrations meet at least twice a year to deepen their cooperation.
