The OECD has published Tax Policy Reforms 2023.
“This is the eighth 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 2022 in 75 member jurisdictions of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting, including all OECD countries. The publication 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 elevated inflation levels, as well as to address long-run structural challenges.”
