If you’re moving to New Zealand, you can legally pay $0 tax on your foreign income for 4 years.
First, what normally happens when you move to New Zealand?
Once you become a New Zealand tax resident:
👉 You are taxed on your worldwide income
That includes:
- Overseas rental income
- Foreign investments
- Overseas business income
But there’s a major exception
New Zealand has a rule called Transitional Tax Residency.
What is ‘Transitional Tax Residency’?
If you qualify, you get:
👉 Up to 4 years where most of your foreign income is NOT taxed in New Zealand
This is one of the most generous tax concessions available.
Who qualifies?
You generally qualify if:
- You become a NZ tax resident, AND
- You have not been a NZ tax resident for at least 10 years
This applies to:
- Returning Kiwis who’ve been away long enough
- Migrants moving to NZ for the first time
What income is actually tax-free?
During the exemption period, most foreign income is not taxed in New Zealand.
This includes 13 categories of income:
- Rental income from overseas.
- Overseas interest and dividends.
- Royalties from overseas.
- Income you earned from working overseas before you came to New Zealand.
- Gains on sale of overseas property (held on revenue account).
- Income attributed under New Zealand’s controlled foreign company rules.
- Income attributed under New Zealand’s foreign investment fund rules.
- Withdrawals from foreign superannuation schemes.
- Overseas income subject to non-resident withholding tax or approved issuer levy.
- Portion of employee share scheme benefits earned from working overseas.
- Accrual income from overseas financial arrangements.
- Foreign-sourced beneficiary income from foreign and non-complying trusts.
- Overseas business income not related to the performance of services.
Important: What this exemption does NOT cover
The exemption does NOT apply to all foreign income. Specifically:
- Foreign sourced employment income
- Foreign sourced income relating to services
What about selling overseas assets?
If you sell foreign assets during the exemption period:
👉 In many cases, New Zealand will not tax those gains
This can create planning opportunities if you are:
- Selling property
- Exiting investments
- Restructuring assets
How long does the exemption last?
The exemption lasts for up to 4 years (technically 48 months), starting from when you become a New Zealand tax resident.
It can end earlier if:
- You opt out
- You or your partner apply for Working for Families
- You become a non-resident again
One thing most people don’t realise
You don’t need to apply for this.
If you qualify, the exemption applies automatically.
But this is a one-time opportunity. Once used, you cannot get it again.
What happens after 4 years?
Once the exemption ends:
👉 You become a normal NZ tax resident
That means:
- Worldwide income is taxable in NZ
- You may need to rely on foreign tax credits to avoid double taxation
The mistakes I see all the time
- Not realising they qualify. Many returning Kiwis assume this only applies to foreigners. It doesn’t.
- Missing the 10-year rule. If you’ve been away for less than 10 years, you won’t qualify.
- Not planning around the 4-year window. This is a limited opportunity. If you’re going to sell assets, restructure investments, or simplify your affairs – you need to think about timing.
- Assuming everything is tax-free. Only most foreign income is exempt. Your New Zealand income is still fully taxable.
The Takeaway
If you’re moving to New Zealand, the first 4 years are your biggest tax planning window. Use it properly, and you can significantly reduce your overall tax. Ignore it, and you’ll likely overpay.
This isn’t a loophole. It’s a deliberate rule designed to attract people to New Zealand. But like most tax rules, it only works if you understand it early.
