Statistics on tax revenue are the foundation for analysis of tax and customs policies. Comparable and reliable statistics are critical to undertake such analysis and to develop better tax policies. The Global Revenue Statistics Database is a major step forward in providing comparable and reliable tax revenue data for a large number of countries from all regions of the world. It provides detailed comparable tax revenue data for more than 100 countries from 1990 onwards. The data are reported at the general level of government and also at the sub-national and social security fund levels.
The key indicators of the database, the tax-to-GDP ratio and the tax structure (the share of a tax category in total tax revenue), allow detailed cross-country analysis and detailed analysis over time and across tax categories. Data are presented along with regional averages for participating African countries, Latin America and the Caribbean (LAC), and the OECD. The database also provides tax revenue data in national currency and in USD.
