This annual publication provides internationally comparative data on tax levels and tax structures in member countries of the Organisation for Economic Cooperation and Development (OECD). The taxes imposed in each country are presented in a standardised framework based upon the OECD classification of taxes and its Interpretative Guide as contained in Annex A to this Report. The data for the Report has, for the most part, been provided by Delegates to Working Party No.2 (WP2) on Tax Policy Analysis and Tax Statistics of the Committee on Fiscal Affairs. The OECD acknowledges the co-operation of the International Monetary Fund, whose classification of tax revenues in the Government Finance Statistics Manual 2014 is in many respects similar to that of the OECD. The most important of the other classifications currently in use is the System of National Accounts (henceforth referred to as SNA) and the European System of Integrated Economic Accounts of EU member states (henceforth referred to as ESA), which is primarily an elaboration of SNA, though differing from it in certain respects. Subject to a few exceptions, SNA/ESA figures can be reconciled with the figures in the present Report, since SNA criteria and definitions have been adopted unless the contrary is specifically indicated.
The material is organised in six chapters. Chapter 1 summarises tax trends over the past six decades, with a focus on tax-to-GDP ratios, tax structures and taxes by level of government. It also discusses the treatment of non-wastable tax credits and provides information on financing of social security-type benefits. This year’s issue also carries in Chapter 2 a special feature on “The impact of COVID-19 on OECD tax revenues”. Chapter 3 contains a set of comparative statistical tables for years 1965-2021. Chapter 4 provides country tables with tax revenue and tax-to-GDP ratios broken down by selected tax categories and by level of government for years between 1990 and 2020. Two memorandum tables show how countries finance their social benefits and report taxes and social security contributions paid by general government as a percentage of GDP. Chapter 5, only available online, provides statistical tables with a detailed breakdown of tax revenues by country between 1965 and 2020. Two memorandum tables show how countries finance their social benefits, and report taxes and social security contributions paid by general government in national currency. Chapter 6, which is also only available online, attributes tax revenues to general government by the following sub-sectors: central, state, local and social security funds. It contains tables that provide a detailed breakdown of tax revenues by country between 1975 and 2020. Because of space limitations, Chapters 4, 5 and 6 show data for selected years between 1965 and 2020; data for the years not shown are available online.
