For Australian expats, the most expensive question isn't how much you earn overseas — it's whether the ATO still counts you as an Australian tax resident. The gap between resident and non-resident treatment can run to tens of thousands of dollars a year, because non-residents lose the tax-free threshold and pay tax from the very first dollar.
Why the status matters so much
Australian residents get the $18,200 tax-free threshold, lower marginal rates on income below $135,000, and the Low Income Tax Offset. Australian non-residents get none of these — they pay a flat higher rate from dollar one, though they're also exempt from the 2% Medicare Levy. For a typical professional salary, residents usually take home several thousand dollars more.
Residency is decided by the ATO's tests, not by which outcome is cheaper for you. You can't simply choose to be a non-resident because the maths is better.
The four tests the ATO uses
You're an Australian resident for tax if you satisfy any one of these:
- The resides test. The primary test — do you actually live in Australia, judged on the whole of your circumstances (where your home, family and life are)?
- The domicile test. If your domicile is Australian, you're a resident unless the ATO is satisfied your permanent place of abode is overseas. This is where many expats are caught — a two-year secondment with a return ticket often isn't enough.
- The 183-day test. If you're in Australia for more than half the income year, you're generally a resident unless your usual place of abode is overseas.
- The Commonwealth superannuation test. Relevant mainly to certain government employees.
The "permanent place of abode" trap
Leaving Australia doesn't automatically make you a non-resident. The ATO looks at whether you've genuinely set up a permanent home abroad: a long lease or property purchase, family with you, cutting Australian ties, and an intention to stay away indefinitely all point to non-residency. A short posting with your family and home left behind in Australia usually does not.
What changes when you become a non-resident
- No tax-free threshold — tax applies from the first dollar of Australian-source income.
- CGT on departure — you may be treated as having disposed of certain assets, or face the foreign-resident capital gains withholding on Australian property.
- HECS/HELP still follows you — overseas income above the threshold still triggers compulsory repayments.
- Franking credits and other concessions are treated differently.
