🎉 The 2026 rankings are in! How competitive is your country’s tax code? See how your country compares with our new interactive tool: hubs.ly/Q04BspXV0 The structure of a country’s tax code is a determining factor of its economic performance. A well-structured tax code is easy for taxpayers to comply with and can promote economic development while raising sufficient revenue for a government’s priorities. In contrast, poorly structured tax systems can be costly, distort economic decision-making, and harm domestic economies. The International Tax Competitiveness Index gives a comprehensive overview of how OECD countries’ tax codes compare, explains why certain tax codes stand out as good or bad models for reform, and provides important insight into how to think about tax policy.
