Next Steps for the UN Convention on Tax: Mapping Priorities
Background
Countries around the world are losing billions to illicit financial flows, tax avoidance, tax evasion, and unfair allocation of taxing rights—reflecting a global tax framework which is no longer fit for purpose. The UN Framework Convention on International Tax Cooperation is our opportunity to reinvent the global tax system for the needs of the 21st century, but what are the next steps?
On July 16, 2025, the International Institute for Sustainable Development (IISD) hosted a live webinar to launch its new research analyzing substantive issues and strategies through which the UN Convention on Tax can best meet its objective: supporting fair and inclusive global tax cooperation.
The launch was followed by a panel of experts, government representatives, academia, and international organizations for focused discussions on protocol areas to give tools to negotiators ahead of the First Session of the Intergovernmental Negotiating Committee on the Framework.
