U.N. Tax Committee Priorities Draw Global Input as International Taxation Evolves

As the U.N. Tax Committee prepares its first session, stakeholder input has tripled from four years ago. Key priorities include dispute resolution, environmental taxation, and adapting tax rules for developing economies in a rapidly changing international landscape.

The United Nations Tax Committee is fielding diverse suggestions from global stakeholders as it prepares to establish its four-year work plan, with particular focus on how international tax rules should evolve to address digital economies, climate change, and the needs of developing countries. The committee’s secretariat received 43 responses to its call for input—nearly triple the participation from four years ago—according to recent analysis of stakeholder submissions.
