This page tracks the combined personal income tax and employee social security contribution rate in South Korea for a single person with no children earning 100% of the average wage — the OECD's standard comparison case. 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.
