The short answer
Your visa says you can live in Australia. The Australian Taxation Office (ATO) asks a different question: are you a resident for tax purposes? The answer decides whether you get the AUD 18,200 tax-free threshold, whether you're taxed on worldwide income, and how your first return works. Visa status and tax residency are separate — a permanent visa doesn't automatically make you a tax resident, and a temporary visa doesn't automatically keep you out.
The four tests (you only need to meet one)
Under section 6(1) of the Income Tax Assessment Act 1936, you're a resident if you meet any one of four tests:
Resides test — the primary test. Do you "reside" in Australia in the ordinary sense of the word? The ATO looks at the whole picture: physical presence, intention, family location, employment ties, where your assets are, and your social and living arrangements. There is no fixed day count — it's a judgment call on your circumstances.
Domicile test — if your domicile is in Australia, you're a resident unless your permanent place of abode is outside Australia.
183-day test — if you're physically present in Australia for 183 days or more in the income year (1 July–30 June, not the calendar year), you're presumed resident unless both your usual place of abode is outside Australia and you have no intention of taking up residence here. Days need not be consecutive; arrival and departure days count.
Commonwealth superannuation test — for certain government employees; irrelevant to most newcomers.
In practice, most new migrants satisfy the resides test well before hitting 183 days — a settled home, a job, and family in Australia is usually enough. The 183-day test mostly catches people whose resides position is borderline.
What residency changes
Residents get the tax-free threshold: the first AUD 18,200 of income is taxed at 0%, then graduated rates apply. You're generally taxed on worldwide income.
Foreign residents (non-residents for tax purposes) get no tax-free threshold — tax starts from the first dollar at 30% (check current rates on ato.gov.au) — but are generally taxed only on Australian-sourced income.
This is why the distinction matters enormously in your first year: a few weeks' difference in when you became resident can move thousands of dollars of income between the two treatments.
Your first year: the part-year return
Most newcomers become tax residents partway through an income year, not on 1 July. Your first return is a part-year return: you're treated as a foreign resident up to the date you became a tax resident, and as a resident from that date onward — all within the same return. Keep records of your arrival date and when your living situation became settled; the ATO can ask.
The Tax File Number (TFN)
The TFN is your personal tax identifier — apply as soon as you arrive (you need a valid visa and an Australian address; it arrives by mail). You are not legally required to give your TFN to your employer or bank, but if you don't:
your employer must withhold tax at the highest marginal rate, and
your bank withholds tax on interest at the highest rate too.
So in practice, hand it over. If you've applied but not received it, you have 28 days to provide it to your employer before the higher withholding kicks in.
Common newcomer mistakes
Assuming the visa decides it. A 482 holder who has clearly settled in Australia is usually a tax resident; a permanent resident who hasn't moved yet usually isn't.
Counting 183 days on the calendar year. The test uses the income year (July–June).
Forgetting worldwide income. Once resident, foreign bank interest, overseas rental income, and capital gains generally enter the Australian return (double-tax treaties may give credits — keep foreign tax receipts).
Not lodging because "I only just arrived." If you earned Australian income, you likely need to lodge even in a part year.
Frequently asked questions
I arrived in March. Am I a resident for that income year?
Possibly, from your arrival date — the resides test has no minimum day count. If your circumstances show you settled here, you're resident from when you arrived, and you lodge a part-year return.
Do I pay tax on money I earned before moving?
Pre-arrival foreign income is generally outside the Australian return for the period you were a foreign resident. Once you're a resident, worldwide income is in scope from the residency start date.
What if my home country also taxes me?
Australia has double-tax treaties with many countries (including China, the UK, and the US). You generally claim a foreign income tax offset for tax paid overseas — keep the foreign assessments.
Can I be a tax resident of two countries at once?
Yes, it happens. Treaties contain tie-breaker rules. This is genuinely complex — get professional advice if you have substantial ties in two countries.
Do I need to file if I earned nothing?
Generally no return is required with no income, but lodging a "non-lodgment advice" with the ATO keeps your record clean. Check the ATO's "do I need to lodge" tool.
