Sources

Every figure on this site comes from one of the three OECD publications below. Values are republished unmodified: we select, rank and format them, and we compute the change from one year to the next, but we never edit a published value.

How to read a missing value

Where the OECD source does not publish a series for an economy, the country page shows the series label, the words Not tracked, and the data note verbatim. Not tracked means exactly that: the source does not publish the series, so we do not publish it either. It is never estimated, borrowed from another country, or filled from a national source.

Attribution

Corporate and personal income tax data are used under OECD terms, with attribution to the OECD. VAT/GST data from Consumption Tax Trends 2024 are used under CC BY 4.0, with attribution to the OECD. The licence line printed under each series names the source and its terms.

Updates and corrections

Figures move when the sources move: corporate and personal income tax series update with the OECD tables, and VAT/GST values update when Consumption Tax Trends is reissued or a country changes its standard rate — Switzerland's move to 8.1% on 1 January 2024 is one change already reflected in the series. If a figure on this site disagrees with the publication it came from, the published value stands: write to contact@younivi.com and we will re-check the ingest and correct the page.
