Tax Expenditures Lab

The Tax Expenditures Lab provides worldwide information on preferential tax treatments such as exemptions, deductions, credits, deferrals and reduced tax rates. Launched in October 2023, the lab hosts the two key projects co-led by the Council on Economic Policies (CEP) and the German Institute of Development and Sustainability (IDOS): the Global Tax Expenditures Database (GTED) and the upcoming Global Tax Expenditures Transparency Index (GTETI).
