The Global Tax Expenditures Database (GTED) is led by the Council on Economic Policies (CEP) and the German Development Institute / Deutsches Institut für Entwicklungspolitik (DIE). It is the result of a multi-year engagement to increase transparency on tax expenditures and the critical role they play in tax systems around the globe. It brings together the official and publicly available data on tax expenditures, as published by national governments since 1990, and makes it available free of charge online. The GTED seeks to contribute to improving transparency, deepening analysis and fostering policy debates on the costs and benefits of tax expenditures and related reforms.

Why focus on Tax Expenditures?

About the Partners

The Council on Economic Policies (CEP) is an international nonprofit, nonpartisan economic policy think tank for sustainability, focused on fiscal, monetary and trade policy.

The German Development Institute / Deutsches Institut für Entwicklungspolitik (DIE) is one of the leading research institutions and think tanks for global development and international cooperation worldwide. It is located in the UN City of Bonn. DIE’s work is based on the interplay between Research, Policy Advice and Training.

The GTED has received funding from several donors. Over the last year, financial support by the German Federal Ministry for Economic Cooperation and Development (BMZ) has given us the opportunity to greatly accelerate the process of collecting data and constructing the website.
