Tax Policy Reforms 2026: OECD and Selected Partner Economies

Tax Policy Reforms 2026 examines how governments are adapting tax systems amid fiscal pressures, economic uncertainty, and long-term structural challenges. Covering reforms introduced or announced in 2025 across 92 jurisdictions, the OECD report analyzes changes to personal and corporate income taxes, social security contributions, VAT and other consumption taxes, environmental taxes, and property taxes. It highlights a continuing shift toward revenue-raising measures while governments also use targeted tax relief to support households, investment, innovation, housing affordability, and the transition to lower-carbon economies.
