Foreign Tax Credits

New Zealand tax residents are taxed on worldwide income. To prevent double taxation, you can claim a foreign tax credit for tax paid overseas. The credit is limited to the lesser of the foreign tax paid or the NZ tax attributable to that foreign income.

Residency for Tax Purposes

IRD uses two main tests: the permanent place of abode test and the 183-day test. If you have a permanent place of abode in NZ, you are a tax resident. Alternatively, if you are present in NZ for more than 183 days in any 12-month period, you become a tax resident.

Double Tax Agreements

New Zealand has DTAs with over 40 countries. These determine which country has primary taxing rights over specific types of income and may provide additional relief from double taxation.

Transitional Resident Exemption

New migrants may qualify for a temporary tax exemption on certain foreign income for up to 4 years. This transitional resident exemption can significantly reduce tax for new arrivals with overseas investments.

IRD-Aligned: Uses 2025-26 tax rates. Foreign income must be converted to NZD. Seek professional advice for complex international tax situations.

Understanding Expat Tax in New Zealand

How your tax residency status affects what you owe to IRD

How does New Zealand decide if I am a tax resident?

You are a New Zealand tax resident if you have a permanent place of abode in NZ, or if you are present in NZ for more than 183 days in any 12-month period. Once you meet the 183-day test, you are treated as a resident from the first day of the 183-day period. This means NZ can tax your worldwide income.

What is the transitional tax exemption for new residents?

If you move to New Zealand for the first time (or return after being away for at least 10 years), you get a 4-year exemption on most foreign income. During this period, you only pay NZ tax on income earned in New Zealand or paid from New Zealand sources. Foreign investment income, rental income, and business profits earned overseas are generally exempt.

What tax rates apply to my NZ income as an expat?

The same rates as any NZ resident: 10.5% on income up to NZ$14,000, 17.5% from NZ$14,001 to NZ$48,000, 30% from NZ$48,001 to NZ$70,000, 33% from NZ$70,001 to NZ$180,000, and 39% on income above NZ$180,000. There is no special expat tax rate — you pay the same as everyone else.

What if I pay tax in another country on the same income?

New Zealand has double tax agreements (DTAs) with over 40 countries, including Australia, the UK, the US, and most of Europe. If you pay tax on the same income in another country, you can usually claim a foreign tax credit in NZ. This credit reduces your NZ tax bill so you are not taxed twice on the same earnings.

Do I need an IRD number as an expat?

Yes. If you earn any income in New Zealand, you need an IRD number. You can apply online through the IRD website. You will need your passport, a NZ bank account, and proof of your visa status. Without an IRD number, tax will be deducted at the non-declaration rate (the highest rate), which is 45% for most income types.

What happens to my KiwiSaver if I leave New Zealand?

If you permanently emigrate from NZ, you can withdraw your KiwiSaver funds (except the government contributions) after being overseas for at least one year. If you move to Australia, your funds can be transferred to an Australian superannuation scheme. While you are overseas, your KiwiSaver account stays open but no contributions are required.

Am I still a NZ tax resident if I move overseas?

You stop being a NZ tax resident if you are absent from New Zealand for more than 325 days in any 12-month period, provided you no longer have a permanent place of abode in NZ. Simply leaving the country is not enough — you need to cut your residential ties and stay away for long enough.

Do I need to file a tax return as an expat in NZ?

If your only income is salary or wages with PAYE deducted, you may not need to file a return — IRD will send you an automatic income assessment. But if you have foreign income, rental income, self-employment income, or need to claim a foreign tax credit, you must file an IR3 return by 7 July each year.
