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, Rhodes, 15-16 September 2022

The heads and deputy heads of tax administrations from all EU Member States met in Rhodes on 15-16 September to discuss a number of important issues including:

  • the impact of mega-trends such as population ageing, technological advancement and climate change on the work of tax administrations
  • the further development of administrative cooperation between Member States in order to fight tax evasion and tax fraud, as well as to improve compliance
  • best practices in implementing digital tools to support the work of tax administrations.

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.
