New Zealand income tax calculator

The most straightforward system on this site, and what that costs

Five rates, one national scale, no regional layer, no separate social insurance contribution, and no general capital gains tax. Of every country covered here, New Zealand is the one where the published scale comes closest to being the whole calculation.

On $80,000 the tax is $16,278 — an effective rate of 20.3% against a marginal band of 33.0%. There is no equivalent of the UK's National Insurance, Germany's social insurance or Canada's CPP sitting alongside it.

There is no tax-free threshold either. The first dollar is taxed, at 10.5%. That is unusual among the countries here: Australia exempts $18,200, the UK exempts its Personal Allowance, Singapore exempts its first band. New Zealand instead sets a low first rate and applies it from the start.

The trade-off is delivered through credits rather than through the scale. Working for Families supports households with children, and the independent earner tax credit reaches a band of lower earners without them. Neither is modelled here, so for an entitled household the figure above is an upper bound.

The tax year runs 1 April to 31 March, which is a third distinct pattern among the ten — different from the UK's 6 April, from Australia's 1 July, and from the calendar year used by most of the rest.

What comes off a New Zealand payslip that is not tax

Three deductions sit alongside PAYE and none of them is in the figure above. Together they can be substantial, and the reason each is excluded is that each depends on a choice or a circumstance the calculator cannot know.

The ACC earners' levy funds the accident compensation scheme that replaced the right to sue for personal injury. It is deducted from wages at a rate set separately from tax and capped at an income ceiling. Every employee pays it.

KiwiSaver is opt-out rather than opt-in for new employees, and the contribution is a percentage of gross pay chosen by the employee, with the employer contributing on top. For anyone enrolled it is a real reduction in what reaches the bank, and the percentage varies by person.

Student loan repayments are compulsory above an income threshold and deducted through the pay cycle. For a graduate they behave exactly like a second tax, and they are the reason two people on the same salary can take home noticeably different amounts.

Add all three and the gap between the tax figure above and an actual New Zealand payslip can be several thousand dollars a year. That is why this page reports the tax rather than claiming to report take-home.

No general capital gains tax, and the exceptions that act like one

New Zealand is one of very few developed countries with no comprehensive capital gains tax. Selling shares or property at a profit generally produces no tax charge, which is a structural difference rather than a rate difference.

That "generally" carries weight. The bright-line test taxes gains on residential property sold within a defined period of purchase, with exclusions for a main home. It is not called a capital gains tax and it functions as one for the properties it catches.

Intention matters too. Someone who acquires property or shares with the purpose of resale can be taxed on the profit as ordinary income under long-standing rules, regardless of the bright-line period. That is a facts test rather than a bright line, and it is where disputes arise.

The absence of a broad capital gains tax shapes behaviour visibly: it is one reason residential property has occupied the place it does in New Zealand household wealth, and it has been the subject of repeated and unresolved political argument.

For comparison purposes, the point is the same one that applies to Singapore on this site: setting one country's income tax scale against another's understates the difference when the base being taxed is not the same.

The scale at four incomes

Because there is no exempt band and the first rate is low, the New Zealand effective rate rises steadily rather than starting near zero and accelerating.

On $40,000: $5,908 of tax, an effective rate of 14.8% with a marginal rate of 17.5%.

On $60,000: $10,221 of tax, an effective rate of 17.0% with a marginal rate of 30.0%.

On $80,000: $16,278 of tax, an effective rate of 20.3% with a marginal rate of 33.0%.

On $150,000: $39,378 of tax, an effective rate of 26.3% with a marginal rate of 33.0%.

The gap between the two columns is the thing to notice, and it is narrower here than in most systems precisely because there is no exempt band pulling the average down at the bottom.

Tax codes, and the one that causes most of the trouble

PAYE is deducted by the employer according to a tax code you declare. For a single job the ordinary code deducts close to the right amount and there is usually nothing to reconcile.

A second job uses a secondary code, chosen by reference to your total income from all sources. Choosing one that assumes a lower total than you actually have produces under-deduction, and the shortfall lands at the end of the year.

Inland Revenue now issues automatic assessments for most people rather than requiring a return, which means an under-deduction surfaces as a bill without anyone having filed anything. That is convenient when the codes are right and unwelcome when they are not.

Student loan and KiwiSaver status are carried on the code too, which is why a code is not merely a rate: it determines several deductions at once.

The check worth doing is the same one that works everywhere: annualise the deduction from a payslip and compare it against a figure like the one above. A large gap in either direction usually means a code that no longer matches the situation.

Where these figures come from

The scale was read off Inland Revenue — Tax rates for individuals on 2026-09-02.

Inland Revenue also publishes a composite table of blended rates for a year in which rates changed part-way through. This page uses the ordinary annual scale rather than the composite, because the composite describes a transition rather than a steady state — and using it for a normal year would produce figures that match no published rate.

The figures are for 2026–27. The New Zealand tax year runs 1 April to 31 March.

What is not modelled is stated under the calculator rather than in a footnote, and there are three items rather than one: The ACC earners’ levy is not included. It is deducted from wages alongside tax, at a rate set separately and capped at an income ceiling, and it is a real reduction in take-home pay. KiwiSaver is not deducted. An employee contributes a chosen percentage of gross pay and the employer contributes on top, so for anyone enrolled the figure here is higher than what reaches the bank. Student loan repayments are not modelled. They are compulsory above an income threshold and deducted through the pay cycle like a second tax.

The arithmetic is deterministic. The AI on this site explains figures it is given and never produces one, in New Zealand as everywhere else here.

How New Zealand compares with the rest of this site

Against Australia, the nearest system, the differences are sharper than the proximity suggests. Australia exempts the first $18,200 and adds a 2% Medicare levy; New Zealand exempts nothing and adds no equivalent levy, funding accident cover through ACC instead.

Against the UK, the contrast is the absence of National Insurance. A UK payslip carries two charges that behave differently and cross over; a New Zealand payslip carries one tax plus ACC, and the tax is the dominant one at every income.

Against Canada, the contrast is the missing layer. Canada stacks a provincial schedule on a federal one; New Zealand has a single national scale and no sub-national income tax at all.

Against the US, it is both of those at once — no state layer, no local layer, no separate payroll tax reaching the employee in the same way — plus no general capital gains tax.

The general lesson, which holds across all ten countries here: the number of separate charges on a payslip varies far more between countries than the headline rates do, and it is the charges rather than the rates that make take-home hard to compare.

Automatic assessments, and when you still have to act

Most New Zealanders no longer file a return. Inland Revenue issues an automatic income tax assessment after the year ends, using information reported by employers, banks and investment providers.

That works well when the tax codes were right and produces a bill when they were not — which is the main reason to check a code rather than assume the system will sort it out. A second job on the wrong secondary code is the usual culprit.

An assessment can still be wrong or incomplete: income from outside the reporting system, deductible expenses, donations tax credits and Working for Families entitlements are all things Inland Revenue may not know about.

Donations to approved donee organisations attract a credit of a third of the amount given, claimed separately. It is one of the few claims that is genuinely worth the paperwork for an ordinary salary earner and it is regularly left unclaimed.

The year ends 31 March and assessments follow from around May. A bill is generally payable in the following February, which is a long gap and a good reason not to be surprised by one.

Four ways a New Zealand estimate goes wrong

Expecting a tax-free threshold. There is not one. The first dollar is taxed at 10.5%, which is different from Australia, the UK, Singapore and most of the rest.

Reading the tax as take-home. ACC, KiwiSaver and any student loan repayment all come off on top, and together they can be several thousand dollars a year.

Using a composite rate table. Inland Revenue publishes a blended set of rates for a year in which rates changed part-way through. Applying those to a normal year produces figures that match no published rate.

Assuming no capital gains tax means no tax on gains. The bright-line test taxes residential property sold within a period, and property or shares bought with the intention of resale can be taxed as ordinary income.

The ACC earners' levy, and why it is not a tax

Every earner in New Zealand pays a levy to the Accident Compensation Corporation. It is deducted from wages alongside PAYE, appears on the payslip next to the tax, and reduces take-home in exactly the same way — which is why it is so often described as a second tax.

It is not one, in the sense that matters here. ACC buys cover: if you are injured, in any way, anywhere, whether at work or skiing or crossing the road, the scheme pays treatment and a share of lost earnings. In exchange, New Zealand removed the right to sue for personal injury. That trade is the defining feature of the system and has no equivalent in any other country on this site.

The levy is charged on earnings up to an annual maximum, which makes it regressive above that ceiling in the same way the US Social Security tax is — a flat percentage that stops. Above the cap the marginal cost of an extra dollar drops, which is the opposite direction from the income tax scale.

The rate is set annually and the cap moves with it. This calculator does not apply it, and the figure shown is income tax only. Anyone reconciling against a payslip should expect the payslip to be lower by roughly the levy, plus KiwiSaver, plus any student loan deduction.

The reason for leaving it out is the same reason the site leaves out every figure it cannot source cleanly for the year being modelled: a levy rate that changed part-way through a period produces a plausible-looking number that matches nothing published. Stating the omission is more useful than estimating it.

KiwiSaver, student loans, and the rest of the deduction stack

KiwiSaver is opt-out rather than opt-in for new employees. The default employee contribution is a percentage of gross pay, with higher rates available, and the employer contributes on top subject to employer superannuation contribution tax.

That employer contribution is itself taxed, at a rate that steps with your total remuneration. It is one of the few places in the New Zealand system where a threshold produces a step in what an employer pays rather than what an employee pays, and it is invisible on most payslips.

Student loan repayments are deducted at a flat percentage of earnings above a pay-period threshold. Because the threshold is applied per pay period rather than annually, someone with uneven income can repay more across a year than their annual income alone would imply.

Stacked together, these are why gross-to-net in New Zealand routinely surprises people arriving from countries with a single deduction. The tax is the largest line, but it is rarely the only one.

Each of these is a separate scheme with its own thresholds, and none of them interacts with the income tax scale. The scale applies to the same taxable income regardless of what else is being deducted, which is a simplification the UK, with its overlapping National Insurance bands, does not offer.

Property, the bright-line test, and what "no capital gains tax" means

New Zealand has no general capital gains tax. It is the headline fact about the system and the one most often over-read.

The bright-line test taxes gains on residential property sold within a defined period after purchase, treating the gain as ordinary income at your marginal rate. The main home is generally excluded. The period has been changed more than once, and which version applies depends on when the property was acquired — which makes it one of the few areas where the date of a past transaction, not the current year's rules, decides the answer.

Separately, and older than the bright-line test, gains are taxable whenever the asset was acquired with the purpose or intention of resale. That applies to shares as much as to land, and it turns on intention at the time of purchase rather than on how long the asset was held.

The practical effect is that a New Zealand investor can face tax on a gain at up to 39.0% while believing the country does not tax gains at all. The absence of a capital gains tax regime does not mean the absence of tax on gains.

None of this is modelled by the calculator, which handles salary and wage income. It is stated here because the gap between the headline and the rules is wide enough that an estimate built on the headline would be wrong.

Questions

How much tax do I pay on $80,000 in New Zealand?

$16,278 of income tax — an effective rate of 20.3% with a marginal rate of 33.0%. The ACC earners' levy, KiwiSaver and any student loan repayment come off on top and are not included.

Does New Zealand have a tax-free threshold?

No. The first dollar is taxed, at 10.5%. That is different from Australia, the UK and Singapore, which all exempt a first band. New Zealand instead sets a low first rate and supports lower incomes through credits such as Working for Families.

What are the New Zealand tax rates?

Five: 10.5% to $15,600, 17.5% to $53,500, 30.0% to $78,100, 33.0% to $180,000, and 39.0% above that.

Is the ACC levy included in this figure?

No. It is deducted from wages alongside PAYE at a rate set separately and capped at an income ceiling, and every employee pays it. Nor is KiwiSaver or a student loan repayment, both of which also come off the payslip.

Does New Zealand tax capital gains?

There is no general capital gains tax. The bright-line test taxes gains on residential property sold within a defined period, with exclusions for a main home, and property or shares acquired with the intention of resale can be taxed as ordinary income. Neither is a comprehensive capital gains tax and both function as one for what they catch.

When does the New Zealand tax year run?

1 April to 31 March. That is a different pattern again from the UK, Australia and the countries using the calendar year, so a figure labelled with a calendar year is describing something else.
