TL;DR
- Moving overseas does not automatically end your Australian tax residency [1].
- The ATO uses four tests: the Resides Test, the Domicile Test, the 183-Day Test, and the Commonwealth Superannuation Test [2].
- Your residency status governs your tax-free threshold access, CGT discount eligibility, and whether worldwide income is taxable in Australia.
- A double tax agreement Australia has with your country of residence may override some ATO rules, but it does not replace them.
- Engaging a Registered Australian Tax Agent before and after you move provides clarity on your residency position and helps avoid compliance issues down the line.
1. Does leaving Australia automatically make you a non-resident for tax purposes?
No, and this is the most consequential misunderstanding in Australian expat tax. Simply boarding a plane and living abroad does not trigger a change in your ATO classification [1]. The ATO determines your status by applying its four statutory tests, and the burden falls on you to demonstrate that you no longer meet the threshold for tax residency. Until you do, you remain taxable on your worldwide income in Australia, just as if you still lived in Sydney.
This matters because many Australians stop lodging a non-resident tax return in Australia the year they move, assuming their overseas employer has covered their obligations. The ATO does not work on that assumption.
2. What are the four ATO residency tests, and which one actually controls your outcome?
The four tests operate in sequence, and each has a different purpose [2]. Understanding what each test is actually measuring is where most generic advice falls short.
| Test | What it measures | Who it most affects |
|---|---|---|
| Resides Test | Your actual behaviour, habits, and degree of connection to Australia | Anyone who has not cleanly severed Australian ties |
| Domicile Test | Whether your permanent home (“domicile of origin”) is Australia, unless your permanent place of abode is now overseas | Australians who own property or have family remaining in Australia |
| 183-Day Test | Whether you were physically present in Australia for 183 or more days in the income year | Inbound workers and frequent return visitors [4] |
| Commonwealth Superannuation Test | Applies to Australian government employees and their spouses/children overseas | Government workers posted abroad [3] |
The Domicile Test is the one that catches the most expats by surprise. If your domicile of origin is Australia and you cannot demonstrate that you have established a permanent place of abode overseas, the ATO will regard you as a resident under this test even if you have not set foot in Australia for years [2].
3. What does “permanent place of abode” actually mean, and why is it contested?
Building on the Domicile Test above, the harder question is always what qualifies as a permanent place of abode overseas. The ATO does not define this by a fixed time period. Instead, it looks at a pattern of factors:
- Whether you have taken steps to permanently relocate rather than temporarily work abroad
- The nature and duration of your overseas accommodation (renting a furnished apartment on a short corporate lease is viewed differently from signing a multi-year residential lease)
- Whether your family has relocated with you
- Whether you have retained a residence in Australia available for your use
- The nature of your employment contract (fixed-term vs. open-ended)
This is why the documentation you establish in year one shapes the ATO’s view for every subsequent year [1]. Consulting a Registered Australian Tax Agent before you relocate ensures your residency evidence is properly structured from the outset.
4. How does a double tax agreement with Australia affect your residency classification?
Stepping back from the technical residency tests, a separate but related concern is whether a double tax agreement Australia holds with your country of residence offers any relief. Australia has tax treaties with more than 40 countries, and these agreements can determine which country has the primary right to tax certain income types [3].
However, there is a critical nuance that is often misunderstood: a double tax agreement does not override the ATO’s domestic residency tests for the purpose of lodgment. You may still be required to lodge a non-resident tax return in Australia and claim foreign tax offsets via the Foreign Income Tax Offset (FITO) mechanism. The treaty determines how your tax liability is calculated and allocated between two countries; it does not exempt you from the obligation to engage with the ATO at all.
Expats living in the UK, USA, UAE, Singapore, Hong Kong, Japan, and Germany are among those in DTA-covered jurisdictions where FITO applications are commonly required to avoid being taxed twice on the same income.
5. What changes when you are classified as a foreign resident rather than an Australian tax resident?
A related but distinct question is what practically changes once the ATO classifies you as a foreign resident for tax purposes. The consequences are significant and span multiple areas of your Australian financial life [4]:
- No tax-free threshold: Australian tax residents can access the tax-free threshold. Foreign residents are taxed on Australian-sourced income from the first dollar, at foreign resident rates.
- No 50% CGT discount on property and shares: Australian tax residents who hold assets for more than 12 months can access the 50% capital gains discount. Foreign residents cannot. This is a major exposure point for expats selling Australian investment properties.
- 15% Foreign Resident Capital Gains Withholding (FRCGW): When a foreign resident sells Australian real property, the buyer is required to withhold 15% of the purchase price and remit it to the ATO. From 1 January 2025, the property value threshold was removed, meaning this 15% withholding applies to all real property sales by foreign residents regardless of value. This is a withholding mechanism, not the final tax, but it creates significant cash flow implications at settlement.
- HECS/HELP repayment obligations: Non-residents with a HECS/HELP debt are required to make repayments based on their worldwide income, not just Australian income. Many expats are unaware of this obligation.
- Medicare Levy exemption: Foreign residents are generally exempt from the Medicare Levy, which is a partial offset to the higher withholding tax rates.
The net effect is that being classified as a foreign resident is not inherently worse than being an Australian resident, but it requires a fundamentally different approach to structuring your Australian financial affairs.
Frequently Asked Questions
Do I need to lodge an Australian tax return if I live overseas?
In most cases, yes. If you have Australian-sourced income (rental income, dividends, interest, capital gains), you are required to lodge a non-resident tax return in Australia regardless of where you live. Failure to lodge can result in penalties and interest charges from the ATO.
How do I formally notify the ATO that I have become a non-resident?
There is no single form you submit to “register” as a non-resident. Your tax residency status is declared each year through your tax return. It is important that this declaration is supported by your actual circumstances, documented clearly in case the ATO reviews your return.
Can I still be an Australian tax resident if I have lived overseas for several years?
Yes. The ATO’s tests, particularly the Domicile Test, do not have a fixed time threshold [1]. Australians who retain a home in Australia, maintain close family ties, or cannot demonstrate a permanent place of abode overseas have been found to remain Australian tax residents even after years abroad.
What is the 183-day test, and does spending less than 183 days in Australia guarantee non-resident status?
The 183-day test presumes you are a resident if you are physically present in Australia for 183 or more days in an income year, unless the ATO is satisfied that your usual place of abode is outside Australia and you do not intend to take up residence in Australia [4]. However, spending fewer than 183 days in Australia does not automatically make you a non-resident. The Resides Test and Domicile Test can still apply independently of how many days you spend in the country.
Are there proposed changes to the residency rules I should know about?
Yes. There have been ongoing discussions about replacing the existing residency framework with a stricter primary test, including a revised 183-day rule [5]. As of 2026, the existing four-test framework remains in force, but expats should monitor ATO announcements given the proposed reforms.
Does a double tax agreement mean I do not have to pay Australian tax?
Not necessarily. A double tax agreement determines how tax obligations are shared between Australia and your country of residence. You may still owe Australian tax on Australian-sourced income and be required to lodge a return, while claiming a Foreign Income Tax Offset to avoid double taxation on the same income.
What happens if I have not lodged Australian tax returns for multiple years?
Outstanding lodgments can attract failure-to-lodge penalties and interest charges. ODIN Tax assists expats with backdated lodgments across multiple years and works to manage penalty exposure through the ATO’s established processes. The important step is to address overdue returns proactively rather than waiting for the ATO to contact you.
