Australia tax residency: 183-day rule, domicile test, and the resides test
The ATO uses four tests to determine Australian tax residency: resides, domicile, 183-day, and superannuation. Here's how each works for inbound expats and outbound Australians.
Australia's tax residency rules are notoriously sticky. The Australian Tax Office (ATO) applies four tests, and meeting any one makes you a resident. For Australians moving abroad, severing residency requires more than buying a one-way ticket, it requires methodically failing each test.
Australia's four residency tests
- Resides test: based on the ordinary meaning of 'resides', physical presence, nationality, family, business and employment ties, lifestyle.
- Domicile test: if your domicile (legal home) is Australia, you're a resident unless you have a 'permanent place of abode' overseas.
- 183-day test: physical presence in Australia for 183 or more days in the income year (1 July – 30 June), unless your usual place of abode is outside Australia and you don't intend to take up residence.
- Superannuation test: applies to Commonwealth government employees and their dependents.
Australia's tax year runs 1 July – 30 June, not the calendar year. If you're tracking against the 183-day test, count days within that window.
The resides test
The resides test is the catch-all. Even without 183 days, the ATO can call you a resident if your behavior shows you 'reside' in Australia. Factors:
- Physical presence, duration and frequency of visits.
- Nationality and citizenship.
- Family, spouse and minor children location.
- Business and employment ties, Australian employer, Australian business interests.
- Maintenance and location of assets, Australian home, Australian bank accounts.
- Social and living arrangements, clubs, gyms, doctors.
The domicile test
Australians have an Australian domicile by default unless they intend to abandon it permanently. Even moving abroad doesn't automatically change domicile. To break the domicile test, you must establish a 'permanent place of abode' overseas, not a temporary one for an assignment, but a settled home.
ATO guidance treats a 'permanent place of abode' as something more than a transitory presence: long lease, family relocated, sale of Australian home, integration into the foreign community. The test is fact-heavy and routinely audited.
The 183-day test
If you spend 183 or more days in Australia during the income year, you're a resident unless both of these are true:
- Your usual place of abode is outside Australia.
- You don't intend to take up residence in Australia.
This is for inbound visitors who happen to spend 6+ months in Australia during a year. The 'usual place of abode' standard requires evidence of a settled life elsewhere.
Leaving Australia: the playbook
- Sell or rent out your Australian home.
- Move your family with you.
- Cancel Australian Medicare (where applicable).
- Update electoral roll status.
- Reduce or cancel Australian banking, super contributions, and investment activity (where appropriate).
- Establish foreign-country domicile with a long lease or property purchase.
- Track Australian days from departure date forward.
Australia has Capital Gains Tax (CGT) Event I1 on residency change, deemed disposal of certain assets at fair market value. Plan for this. The ATO scrutinizes departures to low-tax jurisdictions (UAE, Singapore, Hong Kong).
Track Australian days correctly
Tax Days tracks Australian days against the 1 July – 30 June income year and the 183-day threshold. Configure your tax-year preference in settings, and the app counts days within the correct window.
Frequently asked questions
How does Australia decide if you're a tax resident?
The ATO applies four tests: the resides test, the domicile test, the 183-day test, and the superannuation test (which applies to Commonwealth government employees and their dependents). Meeting any one of the four generally makes you an Australian tax resident, which is why severing residency requires methodically failing each test.
Does Australia's 183-day test use the calendar year?
No. Australia's tax year (the income year) runs 1 July to 30 June, not the calendar year. If you're tracking against the 183-day test, you need to count your Australian days within that window.
Can I be an Australian tax resident with fewer than 183 days in the country?
Yes, generally. The resides test is a catch-all: even without 183 days, the ATO can treat you as a resident if your behavior shows you 'reside' in Australia, looking at physical presence, nationality, family location, business and employment ties, assets like an Australian home or bank accounts, and social arrangements.
How do Australians moving abroad break the domicile test?
Australians keep an Australian domicile by default, so you generally must establish a 'permanent place of abode' overseas: a settled home rather than a temporary posting. ATO guidance points to evidence like a long lease, relocating your family, selling the Australian home, and integrating into the foreign community. The test is fact-heavy and routinely audited.
Is there a tax cost when you stop being an Australian resident?
Generally yes. Australia applies CGT Event I1 on a residency change, which is a deemed disposal of certain assets at fair market value, so unrealized gains can become taxable. The ATO also scrutinizes departures to low-tax jurisdictions such as the UAE, Singapore, and Hong Kong, so planning ahead matters.
