About this Dataset
New Zealand recorded 20.8 % of gross earnings (tax + employee contributions) in 2025. That is unchanged on the previous period. Across 2000–2025 the series ranges from 15.9 % of gross earnings (tax + employee contributions) in 2011 to 21.1 % of gross earnings (tax + employee contributions) in 2007.
This page tracks the combined personal income tax and employee social security contribution rate in New Zealand 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.
