The New International Corporate Tax System

There has been widespread public and political concern that multinational corporations pay less than their “fair share” of tax. This concern propelled international corporate tax reform high up the international political agenda. Following a decade long process, in October 2021, 137 countries agreed the most significant reform of the international corporate tax system in a century. The reform has been hailed as “historic” and “a once-in-a-generation accomplishment for economic diplomacy.” But is the hype around the reform justified? Will it lead to a good international corporate tax system? This seminar will present work that makes a start at answering these questions.

The seminar will be based on a recently co-authored book on the existing international corporate tax system and reform options (Taxing Profit in a Global Economy, OUP, 2021)  as well as work-in-progress that evaluates the recently-agreed reform (including work based on this recent Policy Brief).
