The most recent version (Nov 2025) of the Government Revenue Dataset, launched by ICTD in 2014 and hosted by UNU-WIDER from 2016, is open and free to use. It includes the latest available tax and revenue data for 196 countries, providing a complete picture of government revenue and tax trends over time and allowing for analysis at the country, regional, or cross-country level. The primary data file (core dataset) is available for download in two formats and can be downloaded from UNU-WIDER, which now hosts and updates the GRD.
The GRD aims to present a complete picture of government revenue and tax trends over time and allows for analysis at the country, regional or cross-country level. Where possible, figures are expressed both inclusive and exclusive of natural resource revenues, which helps to overcome a major obstacle to cross-country comparisons in existing data sources.
