This is NOT income tax alone: employee social contributions are included, so the figure is materially higher than a headline income tax rate. Household type matters too — a one-earner couple with two children faces a different rate in most countries. It is published by OECD and updated annually."},{"question":"How current is this data?","answer":"The most recent observation covers 2025. OECD typically publishes this series with a lag of several months after the reference period. The series runs 2000–2025 (26 observations)."},{"question":"What is the long-term trend?","answer":"The series peaked at 21.1 % of gross earnings (tax + employee contributions) in 2007 and reached its lowest recorded value of 15.9 in 2011. The latest reading of 20.8 in 2025 is unchanged on the previous period."}]}
