Welcome to the TAX EXPENDITURES LAB
A hub for expertise, exchange and peer learning on the topic of tax expenditures, the Tax Expenditures Lab provides worldwide information on preferential tax treatments such as exemptions, deductions, credits, deferrals and reduced tax rates. The lab currently hosts 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 Global Tax Expenditures Transparency Index (GTETI).
