The Lisbon International & European Tax Law Seminars 2024/2025

The Lisbon International and European Tax Law Seminars 2024/2025, organised by CIDEEFF in collaboration with the University of Leeds, form part of the ongoing research development programme in International and European Tax Law, under the scientific coordination of Professor Dr Ana Paula Dourado and Professor Dr Rita de la Feria.

The Seminars are designed to promote dialogue between academics and practitioners on current and significant issues in international and European taxation. They benefit from the insights of a distinguished international panel of speakers, contributing to the richness and depth of the discussions.

For this year's edition, ten papers have been selected and will be presented on 7 July across five panels. The session will feature Professor Dr Werner Haslehner as the Keynote Speaker.

To register for the seminar, please contact: cideeff@fd.ulisboa.pt.

The event will be held in english.
