This dashboard is a practical tool for tax analysis, tax policy design and monitoring progress in domestic resource mobilisation. It draws on key indicators from the global and regional Revenue Statistics databases for Africa, Asia and the Pacific, Latin America and the Caribbean (LAC), and the OECD.
These databases contain high-quality, harmonised and detailed data on tax and non-tax revenues across a wide range of economies worldwide.
By enabling cross-regional comparisons of tax and non-tax levels, composition and trends over time, the dashboard sheds light on how different economies raise tax and non-tax revenues and how their level and structure have evolved.
The following charts draw on key indicators from the Revenue Statistics, enabling comparisons across OECD countries and regional averages regarding the level, composition and trends in tax revenues over time.
How to use: Use the search boxes throughout the page to select countries/regional averages, revenue types and year(s).
Tax revenues as a share of gross domestic product (GDP) vary across the OECD, although the gap between the highest and lowest levels has narrowed over time. The OECD average tax-to-GDP ratio has increased over the past decade and remains well above those of Africa, Asia and the Pacific, and Latin America and the Caribbean.
Revenue Statistics supports the analysis and comparison of tax revenues over time. It provides a comprehensive view of how tax levels have evolved across OECD countries, how they compare at a given point in time, and how different sources of taxation contribute to overall revenue.
Tax structures show the composition of tax revenues across different tax types. Income taxes (on individuals and corporations) are the main source of tax revenue in most OECD countries, a pattern that is different from Africa, Asia and the Pacific, and Latin America and the Caribbean, where taxes on goods and services generate most tax revenues, on average.
Examining both cross-country patterns and changes over time provides important insights into how tax systems in OECD are designed, how they have evolved and the extent to which they support countries’ revenue needs and policy priorities.
Revenue Statistics provides detailed information on 63 tax types across all levels of government (general, sub-national and social security funds). This level of detail enables in-depth analysis of revenues across a wide range of policy, sectoral and thematic areas.
One example is trade taxes, including customs and import duties, export taxes, and other taxes on international trade and transactions. Unlike in other regions, these taxes do not generate significant revenues on average across OECD countries.
