Income Tax Calculator

For calculating New Zealand income tax 

This income tax calculator estimates annual income tax for income received after 31 July 2024 by first calculating your profit, the tax amount in each tax bracket and total income tax for the year.

Please note that in the 2025 financial year (1 April 2024 to 31 March 2025), the income threshold rates changed part way through, therefore the annual tax rates and thresholds are composites. The composite rates are not reflected in the calculator below. See the full list of rates for the 2025 financial year on the IRD website.
