Do I have to pay taxes on money earned overseas if I live in New Zealand?
Short answer: probably. Long answer? It depends on your situation.
If you earn income from a foreign job, rent out property abroad, get paid in another currency, or have shares in a company overseas, the IRD likely wants a piece of the pie. And yes, even if that money never lands in your Kiwi bank account.
In this guide, we’ll break down who needs to declare overseas income, what’s taxable, and how to avoid paying more tax than necessary. You’ll also learn how to stay on the safe side with the IRD, because no one wants a surprise letter about penalties.
Simple, clear, and straight to the point. Let’s go.
Who needs to pay tax on overseas income in New Zealand?
If you live in New Zealand and earn money overseas, the IRD might consider it taxable. But it all starts with your tax residency status. This determines whether your worldwide income must be declared — or not.
Are you a New Zealand tax resident?
You’re likely a tax resident if you’ve been in New Zealand for more than 183 days in a 12-month period, or if you have what the IRD calls a “permanent place of abode” here.
For example, if you’re working for a US company from your house in Christchurch, you’re still a New Zealand tax resident. Which means the income you earn — even if it’s paid in USD — must be declared to the IRD.

What if you’re a non-resident or transitional resident?
Non-residents are generally only taxed on income earned within New Zealand. So if you’ve left the country permanently and meet the non-resident rules, your overseas income may be out of the IRD’s reach.
If you’re new to New Zealand, you might qualify for the transitional resident exemption, which means certain foreign income is tax-free for your first 48 months.
This can be a game-changer for new migrants and returning Kiwis — especially those with income from overseas pensions, rentals, or trusts. For more on this, check out our guide on KiwiSaver tax when living overseas.
What types of overseas income are taxable?
New Zealand tax residents are taxed on their global income. That includes anything you earn, receive, or are entitled to — even if it’s earned offshore and kept in a foreign bank account.
Here are common examples the IRD looks out for:
- Wages or salary from a foreign employer
- Rental income from overseas properties
- Dividends from international shares
- Interest from foreign bank accounts
- Pensions or superannuation schemes
- Capital gains from selling overseas assets
- Freelancing income from global platforms
Even inheritances may trigger tax consequences, especially if they produce income. See our full inheritance tax overseas guide for details.
Tip: Even if your overseas bank account earns just a few dollars in interest, it must be reported.
Double taxation: Will I be taxed twice?
This is a big concern for anyone working or investing across borders. The good news? New Zealand has double tax agreements (DTAs) with many countries to stop this from happening.
New Zealand’s double tax agreements (DTAs)
DTAs are official agreements between countries that help avoid double taxation. They determine which country gets to tax what — and often allow credits or exemptions.
New Zealand has DTAs with over 40 countries, including:
| Country | DTA in place? | Notes |
|---|---|---|
| Australia | ✅ | Common for dual-tax claims |
| United States | ✅ | Complex rules apply |
| United Kingdom | ✅ | Pension income often included |
| Canada | ✅ | Rental and wage income covered |
| Singapore | ✅ | Includes self-employed income |
For more information, check the IRD Double taxation treaties
Using foreign tax credits
When there’s no DTA, you may still be able to claim foreign tax credits. That means you reduce your NZ tax bill by the amount you’ve already paid abroad — as long as the income is taxable in NZ too.
You’ll need to keep:
- Foreign tax return copies
- Receipts or proof of payments
- Currency conversions to NZD
How to declare your overseas income in NZ
Declaring foreign income isn’t as tricky as it sounds — but you do need to follow IRD’s rules carefully.
Here’s what to do:
- File an IR3 return (not just the IR3NR)
- Report income in New Zealand dollars using IRD’s exchange rates
- Include gross income before tax deductions
- Keep documentation of any foreign tax paid
- File everything on time
Even if you didn’t bring the money into NZ, it still needs to be declared.

What happens if you don’t declare foreign income?
The IRD is part of global data-sharing networks. They’re receiving more info than ever from overseas tax authorities and financial institutions.
Penalties and interest
If the IRD finds out you’ve left something out, you could face:
- Late payment penalties (up to 150%)
- Compounding interest on unpaid tax
- Risk of audit or multi-year reviews
In short, it’s not worth the risk.
Voluntary disclosure: a way to fix things
Made a mistake or forgot to include something? You can reduce or even remove penalties by disclosing voluntarily.
You’ll need to:
- Act before the IRD contacts you
- Be upfront and complete in your disclosure
- Pay any outstanding tax and interest
