This is the tenth edition of Tax Policy Reforms: OECD and Selected Partner Economies, an annual publication that provides comparative information on tax reforms across countries and tracks tax policy developments over time. The report covers the tax policy reforms introduced or announced in 2024 in 86 member jurisdictions of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), including all OECD countries. The publication also provides an overview of the macroeconomic environment and tax revenue context in which these tax reforms were made, highlighting how governments used tax policy to respond to short- and long-run structural challenges.
