Your New Zealand tax residency status determines whether you pay NZ tax on worldwide income or only NZ-sourced income. Getting this wrong — in either direction — can lead to unexpected tax bills or missed filing obligations. Here is how IRD determines residency.
You are a NZ tax resident if you have a permanent place of abode in NZ (even if you are overseas), OR if you have been present in NZ for more than 183 days in any 12-month period. As a resident, all worldwide income is taxable in NZ. As a non-resident, only NZ-sourced income is taxed. You must actively establish non-residency when leaving — it is not automatic.
The Two Tests for NZ Tax Residency
Test 1: Permanent Place of Abode
This is the primary and more powerful test. You are a NZ tax resident if you have a permanent place of abode in NZ — even if you are overseas at the time.
A permanent place of abode is more than just a house. IRD considers the totality of your circumstances:
| Factor | Points toward NZ residency |
|---|---|
| Own or rent a home in NZ | Strong indicator |
| Family (spouse, children) in NZ | Strong indicator |
| Retain NZ bank accounts | Moderate indicator |
| Own a vehicle registered in NZ | Moderate indicator |
| Keep NZ social ties (clubs, church, etc.) | Moderate indicator |
| Return to NZ regularly | Moderate indicator |
| Employment or business in NZ | Strong indicator |
| NZ driver’s licence, NZ GP, NZ subscriptions | Minor indicators |
Important: If you leave NZ but keep your family home and your partner and children remain — you almost certainly retain a permanent place of abode in NZ and remain a tax resident.
Test 2: The 183-Day Rule
If you do not have a permanent place of abode in NZ, you become a tax resident on the day that you have been present in NZ for more than 183 days in any 12-month period.
- Days are counted by physical presence in NZ (arrival and departure days count as present)
- The 12-month period is any rolling 12 months — not a calendar year or tax year
- Once you hit 183 days, you are resident from the first day of that 12-month window
Non-Residents: Only NZ-Sourced Income Is Taxed
Non-residents pay NZ tax only on income sourced in NZ:
- NZ salary and wages (working in NZ)
- NZ rental income (property physically in NZ)
- NZ business income
- NZ interest (from NZ banks)
- NZ dividends (from NZ companies — with NRWT applied)
Non-residents do not pay NZ tax on:
- Overseas salary (for work performed overseas)
- Overseas rental income
- Overseas investment income
Becoming a Non-Resident (Leaving NZ)
Leaving NZ does not automatically make you a non-resident. To establish non-residency:
- Remove your permanent place of abode — sell or rent out your NZ home (if renting, you may still retain a place of abode if you can return to the property)
- Move your family overseas — your ties are where your family is
- Cut significant NZ ties — close or reduce NZ bank accounts, cancel NZ subscriptions, etc.
- Stay overseas long enough — you need to break both tests
Residency status for the year of departure is complex — you may be a resident for part of the year and a non-resident for the rest (split year). An IR3 covers both periods.
The Transitional Resident Exemption
New migrants (and returning NZ residents after 10+ years away) qualify for a 4-year transitional resident exemption on most foreign-sourced income:
- Passive foreign income (interest, dividends, rent from overseas) is exempt for 4 years
- NZ income and foreign employment income are still taxable
- Very significant for those moving to NZ with overseas investment portfolios
See Overseas Income Tax NZ for full details.
Double Residency
You can be a tax resident of two countries simultaneously. In this case, the Double Tax Agreement (DTA) between the two countries determines which country has the primary taxing right. NZ has DTAs with 40+ countries. Under a DTA, the “tie-breaker” rules determine residency:
- Permanent home (where you have a home available)
- Centre of vital interests (economic and personal ties)
- Habitual abode (where you regularly live)
- Nationality
- Mutual agreement by the two tax authorities
Frequently Asked Questions
I’ve been working in Australia for 8 months. Am I still a NZ tax resident?
Probably yes — if your family home is in NZ and your partner/children remain there, you still have a permanent place of abode in NZ. Duration overseas alone does not break residency.
I sold my NZ house before leaving. When did I become a non-resident?
Your non-residency start date depends on when both tests are broken. If you have no NZ home and have been overseas for sufficient time (breaking the 183-day test), IRD would typically accept non-residency from the date you departed with clear intention to remain away. Get a binding ruling from IRD if the timing is important.
I am a NZ citizen living in the UK. Do I have to file an NZ tax return?
Not necessarily — NZ citizenship does not determine tax residency. If you have no permanent place of abode in NZ and have not been present for 183+ days in any 12-month period, you are a non-resident and only file if you have NZ-sourced income.
