International Business Taxation: Looking Back to Look Forward

About the Event

This conference started with sessions covering the current state of play on Pillars 1 and 2. Current issues of implementation and likely future issues were discussed, including likely developments if Pillar 1 does not go ahead.  

This was the final CBT Summer Conference before Michael Devereux steps down as the Director of the CBT after 17 years at the helm. The final session of the day provided an opportunity for Michael and a panel of distinguished commentators to look back over the momentous developments in international business taxation over this period with a view to identifying lessons to be learned for the present and the future.
