IBFD Dialogues at IFA Cancun 2023

23 October 2023

We are pleased to invite you to our IBFD Dialogues on International Taxation seminar, taking place during the 75th IFA Congress in Cancun. The theme for this special event is 'Exploring New Avenues for Inter-nation Equity: The Role of the OECD and the UN in International Taxation'.

The IBFD Dialogues on International Taxation seminar at IFA Cancun will explore the future avenues of international taxation with special emphasis on the roles played by the two intergovernmental organisations (with a more-than-regional focus) that traditionally deal with inter-nation equity in the allocation of taxing powers.

The dialogues between experienced international speakers will focus on selected technical issues and give concrete evidence on cross-border issues that require the development of a fair and equitable international tax framework.

The IBFD Dialogues are therefore a perfect in-depth supplement to the IFA seminars for a full immersion into technical issues combined with an overall view of tax sovereignty in the era of global tax coordination.
