If you've ever looked at your payslip and done the maths on what the Australian government actually takes, you already know the number. For a $400k earner, it's north of $200k - I wrote about it in detail. But knowing the number isn't the hard part. The hard part is what comes next.
How do you actually stop being an Australian tax resident?
It's not as simple as buying a one-way ticket. There's no form you fill out that says "I'm done". The ATO doesn't care about your intent - they care about your behaviour. And if you get it wrong, you'll be paying Australian tax on your worldwide income even while sitting in a café in Kuala Lumpur.
This guide breaks down the four tests the ATO uses to determine your tax residency, what you need to do before you leave, and how to build a case that holds up if the ATO ever comes knocking.
The Four ATO Residency Tests
The ATO uses four tests to determine whether you're an Australian tax resident. The critical thing to understand is that satisfying even one of these tests is enough to make you a resident for tax purposes - meaning your worldwide income falls under Australian jurisdiction.
To become a non-resident, you need to fail all four. Here they are:
- 1. Resides Test Primary test
- 2. Domicile Test Permanent abode
- 3. 183-Day Test Physical presence
- 4. Commonwealth Super Test Public servants
Let's break each one down.
Test 1: The Resides Test
The Resides Test is the primary and most subjective of the four ATO residency tests. It evaluates whether an individual's behaviour, social ties, and economic connections indicate they still "reside" in Australia. The ATO assesses factors including home location, family ties, bank accounts, memberships, and frequency of return visits.
This is the primary test and the one that trips most people up. It's also the most subjective, which is precisely what makes it dangerous.
The Resides Test asks a single question: do you reside in Australia? As outlined in ATO Taxation Ruling TR 98/17, answering it involves evaluating your entire life - not just where your body is, but where your "heart and home" is.
The ATO looks at factors like:
- The physical location of your home and whether it's available for your use
- Where your family (spouse, dependents) live
- How often and for how long you return to Australia
- Whether you maintain Australian bank accounts, memberships, and subscriptions
- Where you maintain social and economic ties
- Your stated intention to return or stay away permanently
No single factor is decisive, but the ATO considers them collectively. A person living in Singapore who still has a family home in Sydney, an active Woolworths Rewards card, a gym membership at Fitness First, and flights back every six weeks for the weekend? That person still resides in Australia in the ATO's eyes.
The good news is this works both ways. If you've genuinely moved - you've established a home overseas, your daily routine is anchored in another country, and your Australian ties are minimal - the Resides Test works in your favour.
This is the test where intent matters, but only when backed by evidence. Saying "I left Australia" isn't enough. You need to live like you left Australia.
Test 2: The Domicile Test
The Domicile Test is more mechanical than the Resides Test. It asks: is your domicile in Australia, and do you have a permanent place of abode outside Australia?
Your "domicile" is a legal concept - broadly, it's the country you consider your permanent home. For most Australians born in Australia, their domicile of origin is Australia. This doesn't change just because you move overseas temporarily.
However, you can fail this test (which is what you want) by establishing a permanent place of abode outside Australia. The key word is permanent. The ATO has specifically ruled that the following are not sufficient:
- Hotel rooms or serviced apartments
- Airbnb or short-term rentals
- Staying with friends or family
- Month-to-month leases with no intent to stay
What does work is a long-term lease (12+ months) or property ownership in another country, combined with actually living there. You need a proper home overseas - somewhere with your furniture, your belongings, and your daily life.
This is why I signed a 12-month rental in Kuala Lumpur within weeks of arriving. It wasn't just about having somewhere to live. It was about building evidence that I had a permanent abode outside Australia.
If you still own property in Australia that's available for your use, this test gets harder. Renting it out helps significantly - it demonstrates the property is not your home. Leaving it empty is the worst possible option because the ATO can argue it's maintained as a home for your return.
Test 3: The 183-Day Test
Under Section 6(1)(a)(ii) of the Income Tax Assessment Act 1936, the 183-Day Test is the most straightforward: were you in Australia for 183 days or more during the income year?
If yes, you're deemed a resident unless you can prove that your "usual place of abode" is outside Australia and you have no intention of taking up residence.
This test catches two groups of people:
- People who haven't actually left yet. If you depart mid-year, you'll likely have spent more than 183 days in Australia for that tax year. The ATO may treat you as a resident for the portion of the year you were present.
- People who come back too often. If you've "moved" overseas but spend four months a year in Sydney attending events, catching up with people, and working from a spare room, you're at risk.
The 183-Day Test has an important interaction with the Domicile Test. Even if you breach 183 days in a given year, you can argue that your usual place of abode is overseas. But this defence is only credible if you've established genuine ties in another country - which loops back to everything above.
In practice, staying under 183 days in Australia per financial year is the simplest protective measure you can take. It doesn't guarantee non-residency (you still need to fail the other tests), but breaching it makes everything harder.
Test 4: The Commonwealth Superannuation Test
This one is simple. If you're a member of a Commonwealth Superannuation Scheme - essentially certain pension funds for Australian government employees - you're automatically treated as an Australian resident for tax purposes, regardless of where you live.
This primarily affects Australian Public Service employees, members of the military, and certain parliamentary staff. If you're in the private sector or self-employed, this test doesn't apply to you.
If it does apply to you, the path to non-residency requires leaving the scheme. Speak to a specialist about the implications before making that decision.
What to Do Before You Leave
Breaking Australian tax residency requires deliberate action across three areas: cancelling existing Australian ties, notifying government agencies of your departure, and establishing genuine connections in your new country of residence. This process should begin at least 2-3 months before your departure date.
Breaking Australian tax residency isn't something that happens on the day you board a plane. It's a process that starts weeks or months before departure. Here's what I did, and what any good tax advisor will tell you to do.
Cancel and Close
- Bank accounts: Close all Australian bank accounts or reduce them to a single one with minimal activity. Your primary banking should be offshore.
- Memberships and subscriptions: Cancel gym memberships, loyalty programs, professional association memberships, magazine subscriptions - anything that ties you to an Australian address.
- Private health insurance: Cancel your Australian PHI. You'll need health insurance in your new country anyway (and it's likely cheaper).
- Medicare: Notify Medicare that you're leaving Australia permanently. They'll update your status.
- Electoral roll: You can stay on the electoral roll as an overseas voter, but update your address to reflect you're overseas.
Notify
- The ATO: Lodge your change of residency status. You can do this through your tax return or via ATO online services.
- Centrelink: If you receive any payments, notify them of your departure.
- Your employer: If you're continuing to work for an Australian company remotely, your employer needs to know your residency status has changed. This affects PAYG withholding and superannuation obligations.
Establish Overseas
- Sign a long-term lease in your new country - 12 months minimum.
- Open local bank accounts and make them your primary accounts.
- Get local health insurance, phone plan, utilities - all in your name.
- Register with local authorities if your destination country requires it.
- Join local memberships - gym, co-working space, community groups. These all build evidence of establishment.
I think of it as moving your entire paper trail. Every document that used to point to Australia should now point to your new country. The ATO isn't looking at one thing - they're looking at the pattern.
Building a Defensible Case
The burden of proof for Australian tax non-residency falls on the individual, not the ATO. According to ATO guidelines, taxpayers must be able to demonstrate through documented evidence that they have genuinely ceased to reside in Australia and established a life overseas.
The single most important piece of advice I received from my tax advisor was this: document everything.
The ATO can audit your residency status years after the fact. When they do, they won't just look at what you said. They'll look at what you did. And the burden of proof is on you.
Here's what I keep on file:
- Departure records: My outbound flight booking, departure date, and travel history showing I left and didn't come back for extended periods.
- Rental agreements: Every lease I've signed in Malaysia, with start and end dates.
- Bank statements: Showing primary activity in my Malaysian and international accounts, not Australian ones.
- Utility bills: Electricity, internet, water - all in my name at my Malaysian address.
- Local memberships: Gym, co-working, and any subscriptions registered to my Malaysian address.
- Travel logs: A spreadsheet of every entry and exit from Australia, including purpose and duration of each visit.
- Arrival cards: I always tick the "visitor" box when entering Australia, never "returning resident".
My advisor described this as building a "residency file" - a folder that tells a clear story. The story should be: I left Australia permanently, I established a genuine life in another country, and my ties to Australia are minimal and consistent with someone who no longer lives there.
The worst thing you can do is leave a trail of ambiguity. Don't keep your Australian gym membership "just in case". Don't maintain an empty apartment in Melbourne. Don't fly back every month. Every piece of ambiguity is a data point the ATO can use against you.
Common Mistakes That Ruin Your Case
The five most common mistakes that cause the ATO to reclassify overseas Australians as tax residents are: maintaining an available Australian home, spending too many days in Australia, failing to establish a permanent overseas base, retaining excessive financial ties, and not obtaining specialist tax advice before departure.
I've spoken to a number of expats who thought they were non-residents - until they weren't. Here are the most common mistakes I see.
1. Keeping an Australian home "available for use"
Owning a property in Australia isn't the issue. The issue is whether it's available for you to walk in and sleep in. If you own a house that sits empty, furnished, with your belongings inside, the ATO can argue it's your home. Rent it out on a long-term lease or sell it. Short-term Airbnb lets are risky because the ATO can argue the property is still available between guests.
2. Spending too much time in Australia
Even if you're under 183 days, frequent trips back for 2–3 weeks at a time start to add up. They show a pattern of ongoing connection. Limit your visits, keep them short, and always have a clear reason (business meeting, conference) rather than open-ended returns.
3. Not establishing a home overseas
If you're hopping between countries on tourist visas without a fixed address, you're a nomad - but the ATO may still see you as Australian. You need a base. A country where you have a lease, pay bills, and live a routine. The Domicile Test specifically requires a "permanent place of abode" outside Australia.
4. Keeping too many financial ties
Active Australian credit cards, investment accounts with Australian brokers, ongoing direct debits - all of these suggest your financial centre of gravity is still Australia. Move your brokerage to an international platform. Cancel the direct debits. Reduce your Australian financial footprint to the bare minimum.
5. Not getting professional advice
This is probably the most expensive mistake. The cost of a specialist expat tax advisor ($2,000–$5,000 for an initial consultation and plan) is a rounding error compared to the tax bill you'll face if the ATO reclassifies you as a resident. Get advice before you leave, not after.
Don't Forget the Departure Tax
When you cease being an Australian tax resident, the ATO treats you as having sold all your capital gains assets at fair market value on the date of departure. This is known as the "deemed disposal" or departure tax.
You have two options:
| Crystallise at Departure | Defer Until Sale | |
|---|---|---|
| When you pay | At departure | When you actually sell |
| Tax rate | Your AU marginal rate | Your AU marginal rate at time of sale |
| Risk if assets rise | No additional AU tax | Larger gain taxed in AU |
| Risk if assets fall | You overpaid | Smaller gain (or loss) |
| Best for | Moving to 0% CGT jurisdictions | Uncertain future plans |
If you're moving to a jurisdiction with 0% capital gains tax (like Malaysia, UAE, or Singapore), crystallising at departure often makes sense. You pay the tax now at your current marginal rate, and any future gains accrue tax-free in your new country.
If you defer, you remain in the Australian CGT system for those specific assets until you eventually sell them - potentially at a much higher gain. This is a strategic decision and one you absolutely need professional advice on.
I covered this in detail in my Australia-to-Malaysia article.
A Realistic Timeline
Here's what the process looked like for me, from decision to established non-resident:
- Months 1–2: Research and planning Before departure
- Month 3: Consult specialist tax advisor Before departure
- Month 4: Cancel ties, close accounts, notify ATO Pre-departure
- Month 5: Depart Australia, arrive at destination Departure
- Months 5–6: Sign lease, open local accounts, get insurance Establishment
- Months 6–12: Build evidence of overseas life Ongoing
- Month 12+: Lodge tax return as non-resident Milestone
It's not quick. The first tax year is the hardest because it's a partial year - you were a resident for part of it and a non-resident for the rest. Your tax advisor will help you work out the split. After that first year, if your behaviour is consistent, subsequent years are straightforward.
Is It Worth It?
Let me put it bluntly: on a $400k income, the difference between being an Australian tax resident and a non-resident in a 0% jurisdiction is approximately $200,000 per year.
That's not theoretical. That's the literal number. I covered the full breakdown in my cost comparison of Australia vs Malaysia.
The process of becoming a non-resident costs time, effort, and a few thousand dollars in advisory fees. The return is life-changing. Whether the non-financial tradeoffs - adapting to a new culture, navigating foreign bureaucracy, building a new social network - are worth it is a personal decision.
But the financial case is unambiguous. If you're a high-income Australian who works remotely or runs a location-independent business, you owe it to yourself to at least understand the option.
Run the numbers. See what you'd save. Then make an informed decision.
Frequently Asked Questions
What are the four ATO tests for tax residency?
The ATO applies four tests: the Resides Test (primary), the Domicile Test, the 183-Day Test, and the Commonwealth Superannuation Test. You must fail all four to be classified as a non-resident for tax purposes.
How long do I need to be out of Australia to become a tax non-resident?
There is no fixed period. The ATO looks at the totality of your circumstances, not just days abroad. However, spending fewer than 183 days in Australia per tax year is important for the 183-Day Test. The Resides Test is the primary test and evaluates whether your behaviour, ties, and intentions indicate you still "reside" in Australia.
Can I keep my Australian bank account as a non-resident?
Technically yes, but it weakens your case for non-residency. The ATO considers active Australian bank accounts as evidence of ongoing ties. If you keep one, minimise its use and ensure your primary banking is in your new country of residence.
Do I need to sell my Australian property to become a tax non-resident?
Not necessarily, but owning property available for your use in Australia — especially a family home — can fail the Domicile Test. Renting out the property and establishing a permanent home overseas significantly strengthens your non-residency case.
What happens if I fail even one of the four ATO residency tests?
If you satisfy even one of the four tests, the ATO can classify you as an Australian tax resident. This means your worldwide income would be subject to Australian tax, regardless of where you live or earn that income.
How do I notify the ATO that I'm leaving Australia?
Lodge a "Notification of change of residency status" through your tax return or directly through ATO online services. You should also update your address, cancel your Medicare enrolment, and notify Centrelink of your departure.
