The Department of Law of the Faculty of Law, Economics and Finance is pleased to invite you a conference on withholding taxation
Abstract:
This two-day academic symposium focuses on withholding taxation, tailored for legal practitioners and scholars specializing in international tax law. Historically perceived as a necessary and useful avenue to facilitate cross-border taxation of non-residents, a key objective of international and European legal frameworks has long been to reduce or even eliminate the potentially excessive burden it may impose on taxpayers.
While this objective is still at the heart of both legal and practical concerns, withholding taxation may be celebrating a certain renaissance moment, as it is reconsidered as a necessary tool to facilitate efforts to achieve globally fair taxation. The conference aims to explore these developments in the context of the most recent legislative developments and policy discourses at national, European and global level, including via a focus on the practical limitation of relief mechanisms, digital taxation proposals, and the impact of tax treaty law and EU law for investment vehicles.
Language: English
This is a free conference. Registration is mandatory.
