Tax Revenue (% of GDP)

35 years, 1990–2024 · 127 countries · 7 measures

Tax revenue as a share of GDP is how much of a country’s economy its governments collect in taxes — national, regional and local, social security contributions included. It is the OECD’s standard measure of a state’s tax take, compiled under one classification of taxes so that a country in Africa, Latin America or Asia can be read against an OECD member.

This site holds every year from 1990 to 2024, read from OECD’s own data and stored exactly as published.

Precision

The headline is stored to 14 decimals, as published.

Rounded by this site

Never. Tables on screen may show fewer decimals; the files never do.

Changed by this site

Reshaped into one row per country: regional and income-group totals are left out, only the columns listed are kept, each row gets its ISO 3166 code, and some country names are brought to one spelling. No value is recalculated, rescaled or rounded.

Read from the OECD’s Global Revenue Statistics database through its SDMX API: tax revenue reported by national ministries and tax administrations, harmonised by the OECD and its regional partners. The six main tax headings are stored beside the total; the OECD’s regional averages are left out.
