No Time to Read? Here’s What You Need to Know:
- Tax Residency: You’ll still need to check your tax residency status when moving abroad to avoid paying taxes in both countries.
- Overseas Income: Your income might be taxed in both New Zealand and your new country. Double tax agreements (DTAs) can help prevent this, but make sure you understand the rules.
- KiwiSaver: Leaving NZ doesn’t mean leaving your KiwiSaver behind. You can keep contributing, cash it out, or leave it to grow, but make sure you’re aware of any penalties.
- Student Loans: Moving overseas doesn’t erase your student loans. Know the repayment rules and how they change when you’re abroad.
- Double Tax Agreements: A DTA can help you avoid double taxation—check if your destination country has one with New Zealand.
- Tax Traps: Watch out for common pitfalls like time spent in NZ, property income, and overseas trusts that could lead to unexpected tax obligations.
- Tax Professionals: Don’t handle this alone. A tax professional can guide you through the process and ensure you’re compliant with both NZ and your new country’s tax laws.

Thinking about moving overseas? First thing’s first: get your head around the tax stuff. Yeah, it’s not the fun part of your adventure, but trust me, it’s crucial. No one wants to get caught out with tax surprises once they’re settled in their new home, right?
Whether it’s figuring out your tax residency or understanding how double tax agreements work, you’ve got to make sure you’re on top of it before you leave. In this post, I’ll walk you through the must-know moving overseas tax advice, so you don’t end up paying for someone else’s mistakes. Let’s dive in.
Tax Residency – Understanding Its Importance
What is Tax Residency?
Alright, let’s start with the basics. Tax residency is pretty much the place where you’re considered a resident for tax purposes. It’s how the tax man decides if you’re paying taxes in New Zealand or the country you’ve moved to (or both, lucky you). If you’ve been living in New Zealand long enough or have strong ties here, the IRD might still want a piece of your income. Confused? Don’t worry, we’ll clear it up.
Why Does Tax Residency Matter When Moving Abroad?
Here’s the deal: tax residency impacts where and how you pay taxes. If you don’t get this sorted, you might find yourself double-taxed—paying taxes in New Zealand AND the country you’re moving to. Not ideal. So before you pack your bags, it’s crucial to figure out what the rules are for both New Zealand and your new home. And trust me, every country has its own system, so knowing your status will save you a lot of headaches later.
How to Determine Your Tax Residency Status
There are a couple of tests that will help figure out if you’re a tax resident or not. Let’s break them down.
Permanent Place of Abode Test:
This one’s about where you call home. If you’ve got a permanent place to live in New Zealand (your house, your digs, whatever you wanna call it), the tax man might still consider you a resident—even if you’ve packed your bags for overseas.
Day Count Test:
Simple as it sounds. If you spend more than 183 days in New Zealand during any 12-month period, you’re probably still considered a New Zealand tax resident. So if you’re planning a quick escape, this might be something to keep in mind.
Got it? Good. Now, you can start sorting your tax life before you hop on that plane!

Key Tax Considerations for Moving Overseas
Overseas Income and Its Taxation
Here’s the kicker: once you become a tax resident of another country, your overseas income could end up taxed there. So, if you’re earning money in your new country, don’t think you’re off the hook—New Zealand might still want a slice if you’re not careful. This is where the double tax agreement (DTA) comes in handy, but you still need to know the rules. Your overseas earnings might be taxed at the source, but make sure you’ve got the paperwork to avoid paying twice. Get ahead of this and you won’t end up paying more than you should.
KiwiSaver: What Happens When You Leave New Zealand?
Leaving New Zealand doesn’t automatically mean you get to kiss KiwiSaver goodbye. You’ve got a few options here: you can keep contributing to your account (yes, even from overseas), you can stop contributing and leave the money to grow, or you can cash it out. But here’s the catch—if you cash out early, you might end up losing out on some future gains. So, think carefully about whether you want to leave it growing or pull it out while you can. Just don’t forget that you could face some penalties, depending on how you go about it.
Student Loans – How They’re Affected by Moving Overseas
We all know student loans are a pain, and unfortunately, moving overseas doesn’t make them go away. If you’re planning to live abroad, get ready to keep making repayments. You’ll still need to pay your student loan, but if you’re outside New Zealand for more than six months, the rules change. Your loan repayment schedule might adjust based on how much you’re earning and where you’re earning it from. Don’t leave this hanging—make sure you understand how much you owe and when to pay it, or the IRD will come knocking.

Child Support and Family Obligations
If you’ve got child support or working for families benefits to deal with, moving abroad can really throw a wrench in things. Depending on where you move, your child support payments could change. The same goes for working for families—it’s all about where you’re living and what income you’re earning. Don’t just assume everything stays the same. If you’re planning to keep getting those benefits or need to continue child support, check how your move affects your obligations. You don’t want any surprises down the line when you’re trying to get settled.
Hope that clears things up! Now, you can make sure your move doesn’t come with any unexpected tax headaches.
Double Tax Agreements and Their Importance
What is a Double Tax Agreement (DTA)?
Let’s keep it simple: a Double Tax Agreement (DTA) is like a safety net for expats. It stops you from being taxed twice on the same income. Without a DTA, you could end up paying tax in both New Zealand and your new country. Not cool, right? But if your new country has a DTA with New Zealand, you’ll get some relief. The agreement tells both countries how to share the tax responsibility. So, whether it’s your income, your investments, or even your pension, a DTA ensures you’re not paying double tax. That’s why understanding DTAs is a game-changer when moving overseas.
Countries with a DTA with New Zealand
Lucky for you, New Zealand has DTAs with lots of countries. So, if you’re moving to the UK, Australia, the US, or Canada, you’re in luck. These DTAs make things a lot easier by laying out exactly how income will be taxed. For example, in the UK, you might still pay tax on your earnings, but New Zealand will give you a credit for any tax paid over there. Each DTA is different, but the general rule is: these agreements keep you from paying double tax, which is a big win. Always check if your destination country has a DTA before you head off.
What Happens If There’s No DTA?
No DTA? Well, that’s a bit trickier. If there’s no agreement between New Zealand and the country you’re moving to, get ready for double taxation. You’ll pay tax in the country where you’re working, and New Zealand will still want its cut. But here’s the kicker: you might be able to claim some tax credits or deductions, depending on the rules in both countries. It’s not impossible, but without a DTA, it’s going to take more effort to avoid paying double. This is where a good tax advisor comes in handy—don’t leave it to chance, especially if you’re heading somewhere that doesn’t have a DTA with New Zealand.
Now you’ve got the lowdown on DTAs—let’s make sure you’re not paying tax in both places.

Tax Traps to Watch Out For When Moving Overseas
Moving overseas sounds exciting, but let me tell you—it comes with a few tax traps that could catch you off guard. You don’t want to be hit with a surprise tax bill because you didn’t see something coming. The good news is, with a little planning, you can avoid these common pitfalls. To help, I’ve put together a table of the most common tax traps to watch out for when you’re making the big move. Take a look, and save yourself from some serious tax headaches down the line.
Tax Trap | What You Need to Know |
---|---|
Trap 1: Time Spent in New Zealand Before Moving | If you’ve spent more than 183 days in NZ within the last 12 months, you might still be considered a NZ tax resident. |
Trap 2: Residency for Immigration vs. Tax Residency | Immigration residency doesn’t always mean tax residency. Make sure both are sorted before you go. |
Trap 3: Owning Property in NZ While Abroad | If you own property in New Zealand and move to a country without a DTA with NZ, your property income could still be taxed here. |
Trap 4: Overseas Trusts and Tax Liabilities | Be careful if you have overseas trusts. They might become taxable in New Zealand once you become a resident again. |
Don’t let these traps sneak up on you. Stay ahead of the game and get your tax situation sorted before you take off.
Managing Your Tax Situation as a New Zealand Expat
Living overseas as a New Zealand expat can be exciting, but let’s be honest, the tax side of things can be a bit of a headache. Keeping track of your tax responsibilities from abroad isn’t as straightforward as it sounds, but staying on top of it will save you stress and potentially a lot of money. So, how do you manage your tax situation while living overseas?
How to Keep Track of Tax Responsibilities While Living Overseas
First off, it’s crucial to stay organized. As an expat, you might have tax obligations both in New Zealand and your host country, which can get messy if you don’t keep proper records. Here’s how you can stay ahead of the game:
- Know your tax residency status: This will determine where you’re taxed and what you owe. If you’re a tax resident of New Zealand, you’ll likely still need to file a return there.
- Stay on top of deadlines: Make sure you’re aware of the filing deadlines in both countries. Missing one could mean penalties and unnecessary stress.
- Track income from both countries: Keep a record of all your income – from your overseas job, investments, or any side hustles. This will be crucial when it comes time to file taxes.
- Understand the double tax agreement: New Zealand has agreements with several countries to prevent double taxation. Familiarize yourself with this so you’re not paying tax on the same income twice.

Why You Should Consult a Tax Professional
You might be thinking, “I’ve got this, I can manage my tax filings.” But let’s face it, tax laws are complicated, especially when you’re juggling two countries. That’s why seeking expert advice is key. Here’s why consulting a tax professional should be at the top of your list:
- They know the rules: Tax pros are up to date on all the latest laws and regulations, so you don’t have to guess or miss something important.
- They’ll help you avoid mistakes: Small errors can lead to big penalties. A tax expert will make sure your filings are correct and timely.
- Save money: Tax professionals can help you claim deductions, credits, or exemptions that you might not know about, potentially saving you a lot of money.
