New Zealand income tax rates, 2025

On the New Zealand average wage of NZ$83,073, the OECD publishes an average income tax rate of 20.8% and an average employee social security rate of 0.0%, 20.8% between them, leaving net income of NZ$65,781.

This page is a reference, not a calculator

Every figure on it is published by the OECD and cited to the row it came from. This site does not compute New Zealand, because its own arithmetic on the New Zealand schedule misses the published outcome by 0.93 percentage points against a tolerance of half a point, and a number wrong by that much still looks right.

What is actually taken, at three incomes

The OECD models a single person with no children and no other income at three multiples of the New Zealand average wage, and publishes what that person actually pays. These are outcomes rather than statutory rates: everything taken, divided by everything earned.

The same three incomes, in money

The rates above are what the OECD publishes. The amounts below are those rates applied to the gross earnings it publishes alongside them, which is arithmetic rather than a further source, and it is separated from the table above so that nothing computed here can be mistaken for something published. Rounding means the parts may miss the total by a unit.

Read the middle row across: someone on the New Zealand average wage of NZ$83,073 keeps NZ$65,781 of it, and NZ$17,292 is taken. At 67% of the average wage the amount taken is NZ$8,398 and at 167% it is NZ$35,659, so an income two and a half times larger carries a tax bill 4.2 times larger.

The two numbers that decide different things

On the New Zealand average wage the average rate is 20.8% and the marginal rate is 33.0%. Those answer different questions and confusing them is the commonest mistake made with a table like this one. The average rate tells you what your year costs. The marginal rate, 12.2 percentage points higher here, tells you what the next unit of income costs, which is the number that decides whether a rise, a bonus or extra hours are worth taking.

Across the range the OECD publishes, the combined rate moves from 15.1% at 67% of the average wage to 25.7% at 167%, a spread of 10.6 percentage points over an income range of two and a half times. That is a moderate profile, and it means a rate quoted at the average wage is a poor guide to what happens well above or below it.

Nothing above includes what your employer pays. In New Zealand employer social security contributions run at 0.0% of gross earnings, against 0.0% taken from you. The two sides are close to equal, which is unusual and means the payslip shows roughly half of what the contribution system actually costs.

The statutory schedule, as published

In 2025 New Zealand has 5 central government bands, running from 10.50% to 39.00%, with the second rate starting at NZ$15,600. It is shown as a table and nothing more. Set that top figure of 39.00% against the 20.8% actually taken from someone on the average wage, and the distance between a band rate and an average rate is the whole reason the first table exists.

Central government only, and what that leaves out is set out once rather than repeated on each of these pages.

Why New Zealand has no calculator here

For New Zealand the closest reading we could construct missed by 0.93 percentage points, assembling the schedule as: allowance and ladder only. Several other readings were tried and every one of them was further away. On a salary around the average wage a miss of that size is a real amount of money, and a reader would have no way to see it.

On the New Zealand average wage of NZ$83,073 that gap is about NZ$773 a year, which is the amount a reader would have been wrong by without any way to see it. Why half a percentage point is the tolerance, and what a gap of this size usually turns out to be, is set out once rather than on each of these pages.

Where New Zealand sits

Of the 38 jurisdictions the OECD publishes this series for, New Zealand ranks 32 by the combined rate taken from a single person on the average wage, at 20.8%. Immediately above it: Sweden at 22.6%, Israel at 21.4%, Czechia at 21.3%. Immediately below: Switzerland at 18.1%, South Korea at 16.5%, Mexico at 13.2%.

What this page does not tell you

Everything above describes a single person with no children on NZ$83,073, NZ$65,781 of which they keep. It does not describe a couple, a parent, anybody with income other than a salary, or anybody at a New Zealand salary between the three published points. The full list of what this kind of page cannot answer, including how regional taxes are handled and what none of it says about being foreign, is on how these figures are published.

Questions people ask about tax in New Zealand

What is the average income tax rate in New Zealand?

20.8% of gross earnings for a single person with no children on the average wage of NZ$83,073, according to the OECD's own Taxing Wages series for 2025. That is an average rate rather than a band rate: it is everything taken divided by everything earned, so it is always lower than the highest band the schedule reaches.

How much does someone on the New Zealand average wage take home?

NZ$65,781 a year from gross earnings of NZ$83,073, after income tax and employee social security contributions. That is the OECD's published net figure, not a calculation by this site, which is the point of this page: New Zealand is not modelled here and the number therefore comes from somebody who does model it.

Why is there no New Zealand take-home pay calculator on this site?

Because our own arithmetic does not reproduce the published outcome closely enough. Computing tax from the New Zealand statutory schedule and comparing it with the rates the OECD publishes for the same person, the closest reading we could build missed by 0.93 percentage points against a tolerance of half a point. A calculator that is wrong by that much still looks right, which is the reason for the tolerance and the reason this page exists instead.

Is the marginal rate in New Zealand the same as the average rate?

No, and the gap is large. At the average wage the average rate is 20.8% and the net personal marginal rate, which is what is taken from the next unit earned, is 33.0%. The difference is 12.2 percentage points, and it is the marginal figure that decides whether a rise or an extra shift is worth taking.
