Global Tax Justice in 2025

UN Tax Convention | Gender-Transformative Taxation | Make Polluters Pay | GATJ’s Members


“As we close this year, I am proud of how our movement has risen to meet this historic moment with the start of the negotiations for a UN Framework Convention on International Tax Cooperation. Throughout 2025, the Global Alliance for Tax Justice and our members worked tirelessly to ensure that civil society’s voice shaped these debates, underscoring that the ambition and purpose of the UN Tax Convention must be to fix the broken international tax system, ultimately creating global tax rules that work for people and the planet. As negotiations resume in 2026, we know the road ahead will demand even deeper collaboration, and I am confident that together we will continue the work to build a fairer and more just international tax system.”

- Dr. Dereje Alemayehu, Executive Coordinator of the Global Alliance for Tax Justice (GATJ)

UN Tax Convention

Civil society in the Nairobi UN Tax Convention negotiations.

2025 was a historic year for global tax justice. This year, the negotiations for the new legally-binding global tax rules began and will continue until mid-2027. The UN Framework Convention on International Tax Cooperation (UN Tax Convention) is a once-in-a-century opportunity to create a fair and effective international tax system for sustainable development. It has the potential to deliver urgently needed sustainable finance to fund quality public services, development, human rights, gender equality, and climate action. Read GATJ’s latest publication on The Long Road to the UN Framework Convention on International Tax Cooperation ([link removed]) .

Throughout the first year of negotiations, GATJ has continued to bring together ([link removed]) a diverse movement of tax justice advocates to act as a collective voice both inside and outside of the negotiations. Following the third session of negotiations in Nairobi, GATJ and over 190 civil society organizations and trade unions made a joint submission ([link removed]) on the importance of ambition and substance in the UN Tax Convention negotiations. In recognition of GATJ’s leadership in this work, Luis Moreno, Chair of GATJ, was named ([link removed]) one of the top 50 people globally in tax for the second year in a row.

In 2025, GATJ shared the importance of linking financing for development and international tax cooperation ([link removed]) . GATJ’s Secretariat and members took part in the 4th Financing for Development (FfD) Conference in Sevilla providing interventions ([link removed]) and hosting side events ([link removed]) . Ahead of FfD4, GATJ united with advocates on gender, human rights, development, and climate on the need to reform the international financial architecture under the Global Days of Action on Finance ([link removed]) . ([link removed]) In a publication, From Monterrey to Sevilla: International Tax Cooperation in the Financing for Development
Conferences ([link removed]) , GATJ traced the evolution of the FfD process, from the 2002 FfD1 in Monterrey to present-day FfD4 in Sevilla, as well as the origins of the call for a UN Framework Convention on International Tax Cooperation.

In 2026, the UN Tax Convention negotiations will resume in New York in February. GATJ looks forward to continuing uniting civil society to demand an ambitious and robust UN Tax Convention.

Gender-Transformative Taxation

Throughout the year, GATJ’s Tax and Gender Working Group continued to lead the fight for gender-transformative tax systems. GATJ highlighted the need for tax reform to improve care systems ([link removed]) .

In March, the annual Global Days of Action on Tax Justice for Women's Rights brought together feminists and tax justice advocates from around the world under the theme “Progressive Taxation for an Inclusive and Just Social Organisation of Care! ([link removed]) ” Throughout the campaign, GATJ alongside its members and allies held events ([link removed]) from ensuring a gender-transformative UN Tax Convention to financing care systems. GATJ also held an event on the 30th anniversary of the Beijing Declaration.

In June, GATJ’s Tax and Gender Working Group continued advancing feminist taxation, hosting a side event on rethinking care systems ([link removed]) at the 33rd Annual International Association of Feminist Economics (IAFFE) Conference.

Make Polluters Pay

In 2025, the tax justice and climate justice movements came together to demand that governments make polluters pay.

The November session of the UN Tax Convention negotiations took place in parallel to the COP30 climate negotiations. Climate negotiators in Belém highlighted the need for finance while tax negotiators in Nairobi discussed a convention that can deliver billions. GATJ Secretariat and members repeatedly spoke ([link removed]) about the importance of bringing together these two processes to make polluters pay while delivering urgently needed finance for climate action and the just transition.

GATJ and Eurodad launched a report, Make polluters pay: Proposal for a surtax on fossil fuel industries’ profits ([link removed]) . The report shows how taxing fossil fuel companies can catalyze the just transition and mobilize hundreds of billions of dollars for climate action.
