This article presents a detailed overview of the individual income tax framework in New Zealand for the 2025 tax year. The focus is on the current progressive tax brackets, assessment basis, and applicable rates for individuals earning income in NZ.
Overview of Individual Income Tax in New Zealand (2025)
New Zealand applies a progressive tax system to individual income, with taxes calculated based on total annual income. Each bracket has a different rate, so the effective tax rate increases as your income rises. All figures below are quoted in New Zealand dollars (NZD).
New Zealand Individual Income Tax Rates (2025)
The following table summarizes the current income tax brackets and corresponding rates for individuals. These apply on an annual basis and are assessed on total taxable income.
| Income Range (NZD) | Rate (%) |
|---|---|
| $0 – $15,600 | 10.5% |
| $15,601 – $53,500 | 17.5% |
| $53,501 – $78,100 | 30% |
| $78,101 – $180,000 | 33% |
| $180,001 and above | 39% |
Tax System Type and Assessment
New Zealand’s income tax is classified as progressive. Taxes are assessed based on total income, meaning the more you earn, the higher the marginal tax rate on the top portion of your income.
As of 2025, there are no publicly available official surtaxes or additional levies on individual income beyond the standard progressive brackets outlined above. New Zealand does not require a holding period for income to qualify for these rates.
Illustrative Example
For an individual earning $100,000 NZD in 2025:
- The first $15,600 is taxed at 10.5%.
- Income from $15,601 to $53,500 is taxed at 17.5%.
- Income from $53,501 to $78,100 is taxed at 30%.
- Income from $78,101 to $100,000 is taxed at 33%.
This tiered approach means the effective rate is lower than the top bracket applied to all income. Only the portion of income within each bracket is taxed at that respective rate.
Key Features of the New Zealand Framework

Pro Tips for Navigating New Zealand’s Income Tax (2025)
