Most Australian expats assume their tax status is obvious. You left Australia, you live overseas, you pay tax there — so you must be a non-resident for Australian tax purposes.
Not necessarily.
The ATO does not care where you live. It does not care where you work. It does not care which country issued your work visa. The ATO has its own four-test framework for determining tax residency, and if you satisfy even one of these tests, you are an Australian tax resident regardless of where you are physically based.
Getting this wrong is expensive. Australian residents are taxed on worldwide income. Non-residents — foreign residents for tax purposes — are taxed only on Australian-sourced income, at different rates, with different entitlements. The difference between the two statuses can mean tens of thousands of dollars per year, plus significant CGT exposure on Australian property.
Here is how the four tests work.
What “Foreign Resident for Tax Purposes” Actually Means
“Foreign resident for tax purposes” is an ATO classification, not a description of your nationality or visa status. An Australian citizen who has lived in Hong Kong for ten years can still be an Australian tax resident under the ATO’s rules. Conversely, an Australian who moved abroad last year may have already achieved non-resident status if they can demonstrate it cleanly.
The ATO applies the tests in order. You are an Australian tax resident if you satisfy any of the four. You are a foreign resident only if you fail all four.
New financial year, same residency question.
One wrong assumption on your FY2025-26 return can cost tens of thousands.
The Four Tests
1. The Resides Test
The first — and broadest — test asks a simple question: do you reside in Australia?
If you are physically present in Australia for a continuous period of six months or more during a tax year, you satisfy this test. The ATO looks at your routine, your family situation, your employment, and your physical presence. No single factor is determinative, but continuous physical presence for six months is the threshold.
The key word is “continuous.” If you left Australia before completing six months, you do not satisfy the resides test for that year. Breaking the stay — including a brief overseas trip — interrupts the count.
If you departed Australia with a documented intention to leave (employment contract overseas, visa issued, property arrangements made), that intention can rebut the test even if your departure was delayed.
2. The Domicile Test
Domicile is a legal concept that is often confused with residence. Your domicile is where your permanent home is — the country you intend to return to as your ultimate home.
Australian citizens born in Australia are presumed to be domiciled in Australia. That presumption persists until you acquire a domicile of choice elsewhere, which requires more than simply moving overseas. You must demonstrate that you have made your permanent home in another country with no current intention to return to Australia.
This test catches many long-term expats who assume that years overseas have resolved their Australian tax status. The ATO has taken the view that expats who intend to eventually return to Australia — even vaguely, even decades in the future — retain an Australian domicile.
Establishing a domicile of choice overseas requires evidence: permanent residency in the new country, property ownership there, family settled there, no Australian property retained as a home, and clear written intent.
3. The 183-Day Test
This is the most actionable test for working expats who regularly return to Australia.
If you spend 183 days or more physically in Australia during the tax year (1 July to 30 June), you are an Australian tax resident for that entire year. It does not matter whether those days were consecutive. Cumulative presence counts.
The rule is a bright line. Hit 183 days and you are resident for the year, full stop.
For expats who return to Australia for extended family visits, school holidays, or temporary work — particularly those with partners or children who spend more time in Australia — this test is the most common trap. If you spend 100 days over Christmas and another 90 days mid-year, you have crossed the threshold.
Track your days. If you are approaching 160 days in Australia in any tax year, take advice before you book that next flight.
4. The Superannuation Test
The fourth test applies to a narrow group: Australian government employees working overseas and, in some cases, individuals who were Australian tax residents in the previous year.
For most private-sector expats, this test will not apply. If you were a government employee on an overseas posting, or if your situation involves transitioning from prior-year residency, an Australian expat tax specialist should assess whether this test catches you.
If you are departing Australia permanently and held superannuation here, you may also be eligible to withdraw it through the <a href=”https://www.odintax.com/resources/departing-australia-superannuation-If you are departing Australia permanently and held superannuation here, you may also be eligible to withdraw it through the Departing Australia Superannuation Payment (DASP) — a separate ATO process for departing temporary residents and eligible foreign workers.
Why Your Status Matters
The stakes are significant.
If you are an Australian tax resident:
- You declare worldwide income — salary, dividends, rental income, capital gains — to the ATO.
- You pay Australian income tax on that income (less any foreign tax credits under applicable double tax agreements).
- You are eligible for the 50% CGT discount on Australian property held for 12+ months.
- You may be eligible to access the main residence exemption on your Australian home.
- You can offset negatively geared property losses against other income.
If you are a foreign resident for tax purposes:
- You declare only Australian-sourced income (rental income, Australian employment income, Australian-sourced capital gains).
- You pay Australian income tax on Australian-sourced income at non-resident rates, with no tax-free threshold.
- You forfeit the 50% CGT discount on future capital gains (a 22.5% additional tax cost on gains).
- You may lose the main residence exemption on your Australian home if you are non-resident at the time of sale.
- Negative gearing losses on Australian investment properties cannot be offset against overseas income.
The decision to be — or remain — a foreign resident is not simple. Non-residency protects overseas income from Australian tax. But it comes at a cost on the other side: your Australian property portfolio becomes significantly more expensive to sell.
The Traps Expats Miss
Trap 1: The family visit that crosses 183 days. You are based in Singapore, but your partner and children spend school holidays in Australia. You join them for Christmas, Easter, and a mid-year break. Add it up carefully. Many expats hit 183 days without realising it.
Trap 2: The domicile that never moved. You have lived in Hong Kong for seven years, but you still own your Australian family home, your parents are in Melbourne, and you have always said you will “come back eventually.” In the ATO’s view, your domicile may never have left.
Trap 3: Not locking in the cost base on return. When you become an Australian tax resident after a period of non-residency, your overseas assets (shares, RSUs, foreign property) get a new Australian cost base set at their market value on the date your residency commences. If you do not document this on the day, you face Australian CGT on the entire history of those assets, not just the gains earned while you were resident.
What to Do Next
Your tax residency status is the first question an expat tax advisor will ask — because everything else flows from the answer. Which income you declare, which taxes you owe, whether your Australian property sale triggers a large CGT bill, and whether you can claim negative gearing losses all depend on this single classification.
If you are unsure of your status, or if your situation has changed — you moved overseas, you returned for a period, or you are planning to buy or sell Australian property — the right time to get clear on this is before you file, not after.
Your tax residency status determines everything — which income you declare, what you owe on your Australian property, and whether you can access the 50% CGT discount. ODIN’s advisors work with Australian expats across Hong Kong, Singapore, the UAE, the UK, and the US to get this right before it costs you.
