The data is based on a random sample and has been scaled up to population estimates. The sample is 2% of wage and salary earners, and 10% of IR3 filers.
The years refer to income years ended 31 March. Adjustments more than two years after the end of the income year are not included in the table. The 2020 data is now complete, but 2021 data will not be considered complete until after 31 March 2022, and so will be updated next year.
2021 statistics includes data processed to 25 November 2021 only.
This data includes part-year PAYE incomes, and can also potentially include children.
