UN Tax Convention Meeting

A group of organisations, comprising of Global Witness, Tax Justice UK, Oxfam, Greenpeace, War on Want, the Center for Economic and Social Rights, and Amnesty International, held a drop-in event in Parliament on 3 February 2026 to draw attention to  “Why the UK Government must support the the UN Tax Convention” (UNTC). 

The UNTC is an opportunity offering new hope for global tax cooperation, climate finance and sustainable development, through building a just, sustainable and democratic global tax system. It is a crucial opportunity for the UK to raise billions in revenue, and reinstate its role and responsibility as a global leader in tackling international tax abuse.

It could help countries – particularly but not exclusively in the Global South – to reduce debt and reliance on aid, and curb illicit financial flows that deplete public resources, enabling more sustainable development.

The UK Government has shown ambition in some areas relating to the Convention, while there is no progress in others, The Groups say the UNTC process has not received the political scrutiny it deserves, with no involvement from parliament on a major treaty on the future of global tax. The fourth of nine rounds of negotiations (INC4) is taking place in New York in February 2026.
