1. What is the NZ Income Tax Calculator?

The NZ Income Tax Calculator estimates your income tax liability based on your income, tax bracket rate, and any applicable tax credits. It uses the standard New Zealand tax calculation formula.

2. How Does the Calculator Work?

The calculator uses the NZ income tax formula:

Where:

• \( Income \) — Your total taxable income in NZD
• \( Bracket\ Rate \) — The applicable tax rate as a decimal (e.g., 0.175 for 17.5%)
• \( Credits \) — Any tax credits you're eligible for in NZD

Explanation: The equation calculates your gross tax liability then subtracts any tax credits you're entitled to.
