Are you sure you’re not paying more tax than you should?
You have packed your life, crossed the Tasman, and started fresh in Australia. New job, new routine, maybe even a better pay cheque. But here is the uncomfortable question. Do you actually know how your taxes work now, or are you just hoping it sorts itself out?
If you’re a New Zealander living in Australia, getting your tax right isn’t optional. Miss a detail, and you could end up overpaying or facing penalties later. The good news is that there is a clear way to handle it. You just need to understand how the system treats you.
What changes when you move to Australia?
Let’s get straight to the Australian tax for New Zealanders. The biggest shift is your tax residency status.
Australia doesn’t tax you based on your passport. It taxes you based on whether you’re considered a resident for tax purposes. That’s a big deal.
The ATO uses a primary test called the resides test. This looks at whether you actually live in Australia based on your day-to-day life, habits, and ties here. If that test doesn’t clearly apply to you, there are three further statutory tests: the domicile test, the 183-day test, and the Commonwealth superannuation test. You only need to meet one of them to be classified as a resident.
For most New Zealanders moving to Australia, the resides test will be the one that matters.
And no single factor decides it. The ATO looks at the full picture: where you live, where your family is, where you work, and what your intentions are.
So, are you a tax resident or not?
If you’re living and working in Australia, there’s a strong chance you’ll be treated as a tax resident. That means:
- You’re taxed on your worldwide income
- You get access to the tax-free threshold
- You may qualify for certain offsets and benefits
If you’re not considered a resident, you’ll be taxed differently. Usually at higher rates, and without that tax-free threshold.
The problem most people don’t see coming
Here’s where things go wrong.
You land in Australia, start earning, and taxes get deducted. It feels automatic, so you assume it’s correct. But what if your residency status is wrong? What if your income from New Zealand is still being taxed incorrectly?
That’s how people quietly lose money.
A quick scenario
You’re working in Sydney and still earning rental income from a property in New Zealand. You assume both countries will sort it out. But without understanding tax rules, you could:
- Pay tax twice on the same income
- Miss claiming credits you’re entitled to
- End up filing incorrectly in one country
Does that sound like something you’d want to fix later, or get right from the start?
How double taxation agreements help you
Australia and New Zealand have a Double Tax Agreement (DTA). That sounds technical, but it’s actually your safety net.
It’s there to stop you from being taxed twice on the same income.
What does that mean for you?
If you’ve already paid tax in New Zealand, you may be able to claim a credit in Australia. The same applies the other way around.
But you need to declare your income properly and keep records. No records, no claim.
What income do you need to declare?
If you’re an Australian tax resident, you need to declare:
- Salary and wages from Australia
- Overseas income, including New Zealand earnings
- Rental income from property
- Investment income, like dividends or interest
That’s where people hesitate. You might think, “Do I really need to declare that small income back home?” Yes, you do.
Tax rates and what you should expect
Australia uses a progressive tax system. That means the more you earn, the higher your tax rate. If you’re a resident, you benefit from:
- A tax-free threshold on the first portion of your income ($18,200)
- Lower tax rates compared to non-residents
If you’re not classified as a resident, you’ll pay tax from the first dollar. That means that there is no tax-free threshold and no gradual entry into the tax system for non-residents.
What about your KiwiSaver?
This is where things can get confusing.
If you’ve moved to Australia, your KiwiSaver doesn’t just disappear. You generally have a few options:
- Leave it in New Zealand
- Transfer it to an Australian complying super fund
But before you do anything, here is what you need to know.
Not every Australian super fund accepts KiwiSaver transfers. Also, you must transfer your entire balance; partial transfers are not allowed.
One more thing worth knowing: even after a successful transfer, the New Zealand-sourced portion of your KiwiSaver can’t be accessed until you reach age 65. That’s New Zealand’s retirement age, and it follows the money regardless of which country it’s held in.
And once it arrives in Australia, the transferred amount is treated as a personal contribution, which means it counts toward your non-concessional contributions cap. As of 1 July 2024, that annual cap sits at $120,000 AUD. Go over it, and you’ll owe extra tax.
If your total super balance is $2 million or more, your cap drops to zero (meaning no transfer would be allowed). On the flip side, if your balance is below $1.76 million, you may be able to use what’s called the bring-forward rule, which lets you contribute up to $360,000 across a three-year period instead of being limited to $120,000 in a single year. Worth checking before you make any decisions.
Filing your tax return in Australia
The Australian tax year runs from 1 July to 30 June. At the end of the financial year, you’ll need to lodge a tax return. This is where everything gets reviewed:
- Your income
- Your deductions
- Any foreign income
- Tax credits
You can lodge it yourself or use a registered tax agent. If your situation includes overseas income, getting help is often worth it.
The real risk of getting it wrong
Let’s be honest. Taxes aren’t exciting. It’s easy to delay dealing with them.
But here’s what happens when you ignore it:
- You overpay and lose money quietly
- You underpay and face penalties later
- You stress when authorities ask questions
Now compare that to someone who gets it right early. They:
- Keep more of what they earn
- Stay compliant
- Sleep better at night
Simple steps to stay on track
You don’t need to overcomplicate this. Start with these:
- Confirm your tax residency status
- Keep records of all income, including from New Zealand
- Understand how the double tax agreement applies to you
- Review your KiwiSaver position
- Lodge your tax return correctly and on time
These steps aren’t hard. Ignoring them is what creates problems.
