Governments widely use tax incentives to attract and shape investment. When well designed and implemented, tax incentives can support investment policy goals, but the evidence on their performance in practice is mixed. Tax incentives are not always effective at achieving policy goals and can generate significant costs and economic distortions.
The OECD Investment Tax Incentives Database (ITID) provides systematic, comparable data on the design, targeting and governance of investment tax incentives across more than 70 developing and emerging economies. Using consistent classifications, the ITID enables cross-country comparisons and enhances the analysis of policy impacts. By improving transparency and providing granular, standardised information, the ITID supports more effective tax incentive policymaking and better assessment of costs, benefits and economic outcomes.
