How to use this calculator

This calculator estimates how much tax you will pay during a single income year as an individual.

Simply enter your gross income, any deductions, and your tax at each tax bracket will be calculated for you.

The calculator does not take into account any withholding tax, imputation credits, or other tax credits you may have available, or any PAYE you have already had deducted.

It simply calculates how much tax an individual will be required to pay during the year at a certain level of income.

This is a tool only, and none of the information it produces is financial advice. Its accuracy is not guaranteed. Always check your own figures and get advice from your own financial professionals before making decisions.

A worked example

Say you earn $70,000 a year.

It's tempting to think you're "in the 30% bracket" and hand over 30% of the lot. You don't. New Zealand taxes your income in slices: 10.5% on the first $15,600, 17.5% on the next chunk up to $53,500, and 30% only on the bit above that.

Add those slices up and your income tax on $70,000 is about $13,220. That's an effective rate of roughly 18.9% - a long way south of the 30% you might have feared. The calculator does the slicing for you.

Put your income in above to see your real tax and your effective rate.

Quick note: the brackets here are the 2026/27 figures, and they're just here to show how the slicing works. Tax rates and thresholds get tweaked most years, so check ird.govt.nz for the current ones - the maths stays the same either way.

What most people get wrong about income tax

The single most common myth: "if my pay rise pushes me into a higher bracket, I'll take home less." Completely false, and it stops people chasing raises they should grab.

Only the dollars inside the higher bracket get taxed at the higher rate. Everything below keeps being taxed at the lower rates. Cross into the 30% band and just the income above $53,500 pays 30% - every dollar under it is untouched. A raise always leaves you with more in hand. Always.

That's the gap between your marginal rate (the rate on your next dollar - what people quote) and your effective rate (total tax divided by total income - what you actually pay). Your effective rate is always lower. And unlike Australia, New Zealand has no tax-free threshold, so you're taxed from your very first dollar - worth knowing if you're comparing the two countries.
