Tax residency in Australia: a different question from your visa

Why this matters: the rates are genuinely different

An Australian tax resident gets the tax-free threshold — the first $18,200 of income taxed at 0%, as at 2026 — then graduated rates above that. A foreign resident for tax purposes gets no tax-free threshold at all and pays a substantially higher rate from the first dollar of Australian-sourced income; as at 2026 that starting rate is 30% up to $135,000, compared to a resident's much lower starting bracket. Foreign residents also generally don't pay the Medicare levy, because they're not eligible for Medicare.

The practical effect: on the same Australian salary, a tax resident and a foreign resident can end up with materially different take-home pay, because the resident's income is partly untaxed and taxed at a lower marginal rate on the next slice, while the foreign resident's entire income sits in the higher band.

This is why the question isn't academic. If your employer has assumed the wrong residency status for withholding purposes — which happens, especially for people on temporary visas whom payroll systems sometimes default to 'foreign resident' — you could be significantly over- or under-taxed all year, only reconciled when you lodge.

The resides test — the primary one

The first and most commonly applied test simply asks: does Australia, as a matter of ordinary fact, feel like where you live? The ATO looks at things like how long you've been here, whether your accommodation is settled rather than transient, whether your family is here, your social and sporting ties, and whether you're working here in an ongoing way rather than passing through.

There's no single factor that decides it — it's a whole-of-circumstances judgment. Someone who arrives on a skilled visa, signs a 12-month lease, starts a permanent job, and brings their partner is very likely to satisfy the resides test within a short period, often from close to their arrival date. Someone on a short working holiday moving between hostels with no fixed plans is a harder case and might not.

If you clearly satisfy the resides test, you don't need to separately check the other tests — meeting any one of them is enough to make you a tax resident for the relevant period.

The domicile test and the 183-day test

If the resides test is unclear, two backup tests can independently establish residency. The domicile test looks at your legal domicile (broadly, your permanent home in a legal sense) — if your domicile is Australia and you haven't established a permanent home elsewhere, you're treated as a tax resident.

The 183-day test looks at simple physical presence: if you've been in Australia for more than half the income year (183 days or more, which don't need to be consecutive — they can be added up across separate stays), you're treated as a resident unless you can show both that your usual place of abode is genuinely outside Australia and that you have no intention of taking up residence here. For most new migrants who've moved to Australia to live and work, that carve-out doesn't apply, so crossing 183 days is often enough on its own even where the resides test was borderline.

There's also a fourth, narrow test covering Commonwealth government superannuation scheme members working overseas — it won't apply to the vast majority of new arrivals.

Part-year residency: the year you arrive

Most new migrants become tax residents partway through an income year, not from 1 July. The return you lodge for that first year 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, within the same return.

The tax-free threshold is adjusted proportionally for a part-year resident — you get a fraction of the full $18,200 based on how many months you were a resident, plus a fixed small amount, rather than the full-year figure. The ATO's own tools and any registered tax agent can calculate this precisely; it's not something to estimate by hand.

Getting the exact date right matters, because it's the line between two different tax treatments applying to the same income. It's usually the date you arrived with the settled intention to live here, which for most skilled and family visa holders is close to their actual arrival date, but can genuinely be a separate, later date if your circumstances took time to settle (for example, if you arrived to look around before deciding to stay).

This is not the same as your immigration status

Worth repeating because it trips up almost everyone at least once: your visa subclass, whether you hold permanent residency, and whether you're eligible for Medicare are all separate legal questions from tax residency, decided under different legislation for different purposes. A temporary skilled visa holder (subclass 482, for example) who has moved here to live and work is very often a tax resident from soon after arrival, well before any pathway to permanent residency exists. Conversely, an Australian citizen who has genuinely relocated overseas long-term can, in some circumstances, become a foreign resident for tax purposes despite holding a passport.

Don't assume your visa type answers the tax question, and don't assume a migration agent's advice about your visa pathway extends to tax residency — it's a genuinely different specialisation, even though both matter to the same move.

Is tax residency the same as permanent residency?

No — completely different legal concepts decided under different laws. Tax residency is about where the ATO considers you to actually live for tax purposes, using tests like the resides test and the 183-day test. Permanent residency is an immigration status. You can hold one without the other.

Can I be a tax resident on a temporary visa?

Yes. Many temporary visa holders — skilled workers, students staying long-term, partner visa applicants — become Australian tax residents from soon after arrival if they satisfy the resides test or the 183-day test, well before any permanent visa is granted.

How many days do I need to be in Australia to become a tax resident?

There's no fixed day count for the primary resides test — it's a judgment based on your overall circumstances. The separate 183-day test provides a backstop: being here more than half the income year (183 days, which can be non-consecutive) generally makes you a resident unless you can show your usual home is genuinely still overseas with no intention to stay.

What's different about the tax rate for foreign residents?

Foreign residents for tax purposes have no tax-free threshold and pay a higher starting rate — 30% from the first dollar up to $135,000, as at 2026 — compared to residents, who pay 0% on the first $18,200 and a lower rate on the next bracket. Foreign residents generally don't pay the Medicare levy either.

Who decides my tax residency status?

You self-assess it when you lodge your return, applying the ATO's tests to your own circumstances, though the ATO can review and challenge the assessment. If your situation is genuinely borderline — split time between countries, unclear intentions on arrival — a registered tax agent can help you apply the tests correctly.

Should I ask my migration agent about my tax residency?

Migration agents advise on visas, not tax. For tax residency questions, use a registered tax agent listed on the Tax Practitioners Board register. For visa questions, Migratio matches you with a MARA-registered migration agent for free.
