The G20 and OECD action plan to fight Base Erosion and Profit Shifting (BEPS) has been a high impact project in the field of global tax cooperation. This Task Force plans to offer its expertise on the questions how the G20/OECD BEPS project can be implemented and what could follow moving beyond BEPS in order to increase global cooperation in tax matters.

This ranges from the enabling of cooperation through bilateral agreements against double taxation to the benefits and costs of Automatic Exchange of Information, relating taxes and expenditures, and tapping underutilized sources of tax revenues for the financing of the 2030 Agenda.

The Task Force “International Cooperation in Tax Matters” is co-chaired by:
