In this paper we provide short- and long-run tax buoyancy estimates for 107 countries (distributed between advanced, emerging and low-income) for the period 1980–2014. By means of Fully-Modified OLS and (Pooled) Mean Group estimators, we find that: i) for advanced economies both long-run and short-run buoyancies are not different from one; ii) long run tax buoyancy exceeds one in the case of CIT for advanced economies, PIT and SSC in emerging markets, and TGS for low income countries, iii) in advanced countries (emerging market economies) CIT (CIT and TGS) buoyancy is larger during contractions than during times of economic expansions; iv) both trade openness and human capital increase buoyancy while inflation and output volatility decrease it.

This annual publication gives a conceptual framework to define which government receipts should be regarded as taxes. It presents a unique set of detailed and internationally comparable tax data in a common format for all OECD countries from 1965 onwards.

This paper provides new empirical evidence on tax buoyancy (tax revenues responsiveness to changes in economic activity) over the period 1990-2020 using a large panel of 185 countries. This study compares short-term and long-term buoyancy coefficients for total tax revenues and different individual taxes by reviewing and contrasting a range of estimators. Our results broadly confirm the main body of the literature on long-term buoyancy hovering around one. We find evidence of lower estimates for short-term buoyancy relative to previous literature, suggesting a limited automatic stabilization power of taxes. As a robustness exercise, in addition to changes in tax rates, we introduce novel control variables for tax exemptions and bases to disentangle discretionary from automatic tax revenue changes. The marginal changes in the results when controlling for policy actions suggest that, on average, the economic cycle does not necessarily influence tax reforms.

This annual publication gives a conceptual framework to define which government receipts should be regarded as taxes. It presents a unique set of detailed and internationally comparable tax data in a common format for all OECD countries from 1965 onwards. This year’s edition includes a special feature on tax revenue buoyancy in OECD countries.

This annual publication compiles comparable tax revenue statistics for 36 economies. Additionally, it provides information on non-tax revenues for 22 of the 36 economies. This eleventh edition of the report includes a special feature on tax revenue buoyancy in Asia.

This is the seventh 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 71 member jurisdictions of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting, including all OECD countries, for the 2021 calendar year. In addition to providing an overview of tax policy reforms, and the macroeconomic and tax revenue context in which measures were introduced, the report also contains a Special Feature that examines government responses to rising energy prices and offers some policy recommendations in the event that prices remain high.

This publication explores the policy options to finance more resilient health systems whilst maintaining fiscal sustainability. It finds that the scale of the additional health financing needs requires ambitious and transformative policy changes.
