Income Tax in New Zealand Explained

The first payslip is when it gets real. You open it expecting a number, and instead you get a tax code you’ve never heard of, a levy you didn’t know existed, and a total smaller than you budgeted for. We had exactly that moment ourselves, more than once, over our ten years living and working in New Zealand, before we worked out that “M”, “ME” and a chunk of secondary tax weren’t typos.

The good news is that New Zealand’s tax system really is simpler than the UK’s or the US’s in some ways: one flat set of national rates, no separate national insurance, and no state or local income tax on top. The catch is that almost nobody explains the vocabulary before you need it. This guide walks through how income tax actually works here in 2026, checked directly against Inland Revenue’s own current published rates, so you know what should be coming off your pay before it happens.

This is a plain-English explainer, not personalised tax advice. Every figure below is attributed to Inland Revenue (IRD) and current as of July 2026, but your own circumstances can be more complicated than a blog post allows for. Confirm anything that matters to you with IRD directly or a New Zealand accountant.

How income tax works in New Zealand

New Zealand runs on a pay as you earn system, PAYE for short, which will feel broadly familiar if you’ve had a payslip in the UK. Your employer deducts income tax, the ACC earner levy and, if you’re a member, your KiwiSaver contribution before your wages land, and pays it all straight to Inland Revenue for you. You never see the gross figure and have to set tax aside yourself.

Inland Revenue, almost always just called “IRD”, is the only tax office. There’s no equivalent of UK national insurance running alongside income tax, and no city, state or provincial income tax layered on top the way there is in the US. Income tax, the ACC levy, and KiwiSaver if you’re opted in: that’s what comes off your pay.

New Zealand’s tax year runs 1 April to 31 March, not the calendar year and not the UK’s 6 April cycle. Employees on the right tax code generally don’t need to file an annual return, IRD reconciles automatically. Self-employed people and anyone with untaxed income, like rental income, usually do need to file an Individual income tax return, an IR3, each year.

The 2026 income tax brackets

Income tax here is progressive, the same principle as the UK and US: you pay increasing rates only on the portion of income that falls into each band, not one flat rate on everything. IRD’s current published rates, effective from 1 April 2025 and unchanged for the 2026 to 2027 tax year, are:

Income band	Tax rate
$0 to $15,600	10.5%
$15,601 to $53,500	17.5%
$53,501 to $78,100	30%
$78,101 to $180,000	33%
$180,001 and over	39%

Source: Inland Revenue, Tax rates for individuals, last updated 3 June 2025.

So someone earning $70,000 pays 10.5% on the first $15,600, 17.5% on the next slice up to $53,500, and 30% only on the remainder, not 30% on the whole amount. IRD’s own income tax calculator on myIR is worth using for your actual numbers. Employees also have the ACC earner levy deducted on top of these headline rates, covered below, so the real deduction is a little higher than the table alone suggests.

Tax codes: which one is actually yours

This trips up almost every newcomer, us included. Your tax code isn’t a description of how much tax you pay, it’s an instruction telling your employer which rules to apply, declared on the Tax code declaration form, IR330, when you start a job.

Code	Who it’s for
M	Your main (or only) job, no student loan, no Independent Earner Tax Credit or Working for Families
ME	Your main job and you qualify for the Independent Earner Tax Credit, broadly total income between $24,000 and $70,000, no Working for Families
M SL / ME SL	Same as above, with a New Zealand student loan
S, SH, ST, SA	A secondary job or income source, the letter depends on total estimated income across all sources
WT	Contractors and freelancers paid under schedular payments
ND	No tax code declared, so your employer deducts tax at the non-declaration rate of 45%, plus the ACC levy, until you sort one out

The classic newcomer mistake is picking up a second job or casual shift without realising it needs a secondary code, not another “M”. Your main job is whichever pays most; everything else is secondary, so your combined income across jobs is taxed at roughly the right rate overall, rather than under-taxed at the lowest band on each payslip. IRD’s tax code tool, and the IR330’s own flowchart, will work out the right one if you’re unsure.

Getting your IRD number

You need an IRD number before you can be paid correctly, open certain accounts, or interact with IRD at all. It’s a unique eight or nine digit number that follows you through every job, bank account and government interaction involving tax, ACC or KiwiSaver.

If you’ve recently arrived on a visa, IRD has a streamlined “new arrival” application that verifies your identity directly with Immigration New Zealand, so you don’t post in the same documents twice. You’ll need your passport details and Immigration New Zealand application number, plus your most recent overseas tax number if you’re on a work or student visa. It’s free to apply, and if approved, IRD typically confirms your number by text or email within a couple of days, with the letter following by post within about ten days.

There’s a time limit on this route, broadly, you need to apply by the date your visa required you to arrive. Miss that and you’ll use the standard “living in New Zealand” application, which needs more identity verification, generally including a working New Zealand bank account. That’s the real reason people are told to sort a bank account first: without one, the fallback application is more paperwork, not less. Our guide to setting up in New Zealand: IRD, bank and phone walks through that order in full.

The ACC earner levy

New Zealand doesn’t run a private health and disability insurance market the way the US does. Instead, ACC (the Accident Compensation Corporation) provides no-fault personal injury cover for everyone in the country, resident or visitor. Employees fund part of that through the ACC earner levy, deducted alongside PAYE.

For the tax year running 1 April 2026 to 31 March 2027, the levy rate is $1.75 per $100 of earnings (1.75%), charged up to a maximum of $156,641 of annual income, capping the maximum levy at $2,741.22 a year. Above that threshold, no further levy is deducted; it’s separate from, and added on top of, the income tax bands above.

It isn’t quite the same as UK national insurance, though people compare it constantly. NI part-funds a state pension and various benefits; the ACC levy funds one thing, no-fault accident cover. New Zealand Superannuation, the state pension, is entirely separate and funded from general taxation, not a payroll levy.

The transitional resident exemption for newcomers

This is the one that genuinely surprises people, worth knowing even if you never need it. New migrants, and New Zealanders who’ve been away at least 10 years and are moving home, may qualify as a “transitional tax resident” and get a temporary exemption from New Zealand tax on most foreign income, for around four years after becoming a New Zealand tax resident.

Most foreign-sourced income is covered, including overseas interest, dividends, foreign investment fund income and rent from a property you still own back home. It does not cover income earned overseas from employment or personal services, so if you’re still paid by an overseas employer for work done while resident here, that generally isn’t exempt, though a double tax agreement may reduce double taxation. You qualify automatically if eligible, can only use it once in your lifetime, and it ends earlier if you apply for Working for Families or choose to opt out.

The exemption period runs from when you first became a New Zealand tax resident (broadly, once you’ve spent more than 183 days here in any 12 month period, or set up a permanent home, whichever comes first) for four years from the end of that month.

Working out your own dates, and whether overseas income still coming in counts as exempt, gets genuinely fiddly, worth an accountant’s time, particularly if you’re also transferring a pension. Our guide to transferring money and your pension to New Zealand covers the practical side.

GST if you’re self-employed

Goods and Services Tax, GST, is New Zealand’s answer to VAT in the UK or sales tax in the US, a consumption tax charged at 15% on most goods and services. As an employee you pay it every time you buy something, already built into the shelf price, and never think about it again.

Self-employed? Different story. IRD requires you to register for GST once turnover reaches, or is expected to reach, $60,000 in any rolling 12 month period; you can register voluntarily below that too. Once registered, you charge GST on invoices, claim back GST paid on business expenses, and pay IRD the difference, usually every two months.

Contractors and the self-employed also handle income tax differently to PAYE employees: no automatic deduction, so you’re generally responsible for paying provisional tax yourself, in instalments through the year, based on an estimate of what you’ll owe. New Zealand largely runs on a voluntary disclosure model, so setting money aside from your first invoice isn’t optional in practice, even though nobody deducts it for you.

No capital gains tax, but the bright-line test on property

New Zealand doesn’t have a general capital gains tax. Sell shares, an investment fund or most other assets for a profit later and that gain typically isn’t taxed the way it would be in the UK or the US, provided you weren’t in the business of buying and selling that kind of asset.

Residential property is the exception. IRD applies the bright-line test: buy and sell a residential property within a set period and any profit is taxable as income, unless an exclusion applies. For property sold on or after 1 July 2024, that window is two years from your bright-line start date (broadly, when you took ownership) to your end date (broadly, when you signed to sell). Property sold before that date is assessed under older 5 or 10 year rules, depending on when it was bought. The test generally doesn’t apply to your main home, business premises, farmland, or an inherited property. It’s a targeted rule against short-term property trading, not a broad tax on selling your house.

How this compares to the UK and the US

Moving from the UK, the biggest adjustment is structure, not rates. There’s no national insurance running alongside income tax; the ACC levy is narrower and single-purpose, and doesn’t fund a pension. For 2026/27, the UK personal allowance is £12,570, basic rate 20% up to £50,270, higher rate 40% up to £125,140 and additional rate 45% above, with employee NI at 8% between £242 and £967 a week and 2% above (gov.uk and House of Commons Library, 2026/27 rates). New Zealand has no tax-free personal allowance, tax applies from the first dollar, but the lowest band, 10.5%, sits well under the UK’s 20%.

Moving from the US, the difference is federal versus state tax. You’d typically file federal income tax (roughly 10% to 37%), a separate state income tax in most states, sometimes a city tax too, plus FICA payroll tax for Social Security and Medicare. New Zealand has one tax authority and one set of national rates; councils fund themselves through property rates, not income tax. It simplifies the paperwork, even if the top rate, 39%, is higher than most people expect.

As a rough guide, in mid-July 2026 NZ$1 was worth about £0.43 and around US$0.58 (Xe.com mid-market rate, 16 to 17 July 2026); rates move daily, so check a live converter before budgeting.

Your questions answered

Do I need an IRD number before I can start work? You can start without one, but your employer must deduct tax at the non-declaration rate, 45% plus the ACC levy, until you provide a valid tax code. Apply as soon as you land, ideally right after opening a bank account.

What tax code should I use as a newcomer? For most people starting their first and only job here, with no student loan and no Working for Families, that’s code M. If your total income sits between $24,000 and $70,000 with no other income, ME may apply instead. IRD’s online tool or the IR330 flowchart confirms which is right.

What happens if I don’t have a tax code sorted before payday? Your employer deducts tax at the non-declaration rate of 45%, plus the ACC levy. You’ll get the difference back once your correct code is in place, but it’s an unpleasant first payslip, so sort it before you start.

Is my UK or US income taxed while I’m still overseas or mid-move? New Zealand only taxes tax residents on worldwide income, and residency is usually triggered by more than 183 days here in a 12 month period, or a permanent home. Not yet resident? Overseas income before you arrive isn’t a New Zealand tax matter.

Does the transitional resident exemption cover my salary if I keep working for my old overseas employer remotely? Generally no. IRD excludes income from overseas employment or personal services, even though it covers passive income like foreign interest, dividends and rent. A double tax agreement may help, but check with an accountant rather than assume.

Do I need to file a tax return every year? Employees on the correct tax code with no other income usually don’t, IRD reconciles automatically at year end (31 March). Self-employed, or with rental or other untaxed income, you’ll typically need to file an Individual income tax return, an IR3.

Is there a capital gains tax in New Zealand? Not a general one. Shares, funds and most other assets aren’t taxed on sale the way they are in the UK and US. The exception is residential property sold within the bright-line window, two years for property sold on or after 1 July 2024 (older 5 or 10 year windows apply to property sold before that date, depending on when it was bought).

How is self-employed or freelance income taxed differently from a salary? No PAYE is deducted automatically, so you’re responsible for setting tax aside and generally paying provisional tax in instalments. You’ll also need to register for GST once turnover reaches $60,000 in a rolling 12 month period.

Not quite the whole picture, on purpose

Tax touches nearly everything else about moving here: your first payslip, your KiwiSaver decision, any pension you bring with you, and what a property sale might cost inside the bright-line window. We’ve kept this guide to income tax specifically. For KiwiSaver and whether it’s worth opting in as a newcomer, see our breakdown of the pros and cons of the KiwiSaver scheme, and if you’re still weighing up the visa route that gets you here, our page on the working holiday visa is a good next stop.

For the fuller, step-by-step version, tax codes, IRD paperwork, the exemption, and how it fits the wider move, the income tax chapter of our guide to moving to New Zealand goes deeper than one page can. If anything here doesn’t quite match your situation, that’s normal with tax.
