Gaëtan ZEYEN

Gaëtan Zeyen has been a lawyer at the Brussels bar for twenty years. He is moreover an arbitrator and, as such, member of various Belgian and foreign arbitration institutions (Cepani; Association française d’Arbitrage; Chambre arbitrale de Vienne).

His professional practice tends toward economic law, and more particularly towards the various aspects of tax law, both Belgian and international (European and OECD) – as well as that of the law of companies in difficulty and arbitration law (Belgian or international).

His interventions cover not only the contentious, but also the non-contentious aspects of a tax case. He furthermore advises his clients in the context of non-aggressive tax planning, both at corporate, and at individual level.

In addition to his involvement with the Brussels Bar (he is a member of the Bar’s tax law committee), Gaëtan is also pursuing an academic career, and more particularly a doctoral degree. In this respect, his favorite field of research is that of double taxation conventions.

He is a member of the tax law research group of the Centre de Recherche Interdisciplinaire Droit, Entreprise et Société (CRIDES) of the UCLouvain and the Tax Institute of Liège.

He has published numerous articles in the field of taxation (mainly international) and arbitration. He regularly delivers training courses or seminars in tax law.
