New Coalition to Drive Reform on Tax Expenditures Launches at FFD4 in Seville

New coalition builds on years of research and technical support to help governments reform tax expenditures and strengthen public finances.

July 1, 2025

Seville, Spain – July 1 – Five leading global research and policy organizations launch a coalition to accelerate reforms of tax expenditures through evidence-based research and technical assistance on the opening day of the Fourth Financing for Development Conference (FfD4) taking place in Seville this week.

Governments worldwide forego an estimated 4% of global GDP—around a quarter of all tax revenues—each year through tax holidays, exemptions, and incentives. Most of these tax expenditures are untracked, unevaluated, and underreported, continuing without clear evidence of impact. This creates a major fiscal drain, leaving fewer resources for infrastructure, health, education, climate action, and other development priorities.

With the Compromiso de Sevilla calling for "enhanced oversight and management of tax expenditures," the FfD4 outcome provides a clear mandate and momentum for this initiative, ensuring the agreement leads to concrete actions like standardized reporting to improve transparency and oversight, and the rationalization of ineffective tax expenditures. 

The new initiative will scale up research and independent technical support to governments, exchange expertise and best practices, leverage complementary strengths from different members to provide holistic support, and work on strengthening international momentum, ensuring tax expenditure reforms remain a priority in forums like FfD4. 

As of now, the United Kingdom, Brazil, France, Guinea, Nigeria, Rwanda, Senegal, and Spain have already endorsed the initiative, signalling growing political will to bring transparency and accountability to this area of public finance.
