Hein Vermeulen’s research focuses on the influence of EU law and international law on national fiscal regimes for collective investment institutions, including real estate investment institutions. He also studies the possible design of European harmonisation of national fiscal regimes. Vermeulen’s research is firmly embedded in the research programme of the Amsterdam Centre for Tax Law (ACTL), one of the Faculty of Law’s centres of excellence. The objective of the research programme is to pinpoint the restrictions placed on national tax sovereignty by international and supranational law. In this regard, he explores the question as to whether such restrictions should be tightened or loosened on the basis of different criteria, including EU freedoms of movement and interjurisdictional equality. 

Vermeulen has worked as an assistant professor of Tax Law at the UvA since 2007. In 2012 he was named professor by special appointment of International Fiscal Aspects of Collective (Real Estate) Investment Institutions at the UvA. This special chair has now been converted into a standard chair. Vermeulen is chairperson of the Faculty of Law’s Tax Law Programme Committee and is responsible for teaching and learning in the field of international and European tax law. He also works at the EU Direct Tax Group (EUDTG) of PricewaterhouseCoopers.
