- The ATO uses four residency tests, and you only need to meet one to be treated as an Australian tax resident. It isn’t a simple day count.
- If you’re a resident, Australia taxes your worldwide income; if you’re a foreign resident, only your Australian-sourced income is taxed.
- Your status changes your CGT discount, which returns you lodge, and how you should structure an Australian company. So it’s worth confirming before you act.
Moving back to Australia? You become a tax resident the moment you meet any one of the ATO’s four residency tests: resides, domicile, 183-day, or superannuation. Just one is enough. And here’s the catch: it isn’t really about days. You can spend well over 183 days here and still be a non-resident, or fewer and still get caught.
That one call decides whether Australia taxes your worldwide income or only what you earn here, so it’s worth nailing down before you act. If you’re coming back to contract, run a business, or set up a company, it shapes your CGT discount and how you structure things, which is exactly what Sleek sorts out for returning founders and contractors.
Confirm your residency position before your first lodgement after moving, not at tax time. Once you've lodged on the wrong basis, fixing it means an amended return and a possible ATO query, far more work than getting it right upfront
Australian tax residency at a glance
Question | Answer |
|---|---|
How many tests? | Four (resides, domicile, 183-day, superannuation). Meet any one and you’re a resident. |
If you’re a resident | Taxed on worldwide income, with foreign income tax offsets to reduce double tax. |
If you’re a foreign resident | Taxed only on Australian-sourced income; no tax-free threshold. |
Why it matters for business | Affects your CGT discount, the return you lodge, and how to structure a company. |
Are you an Australian tax resident when you return from overseas?
Usually, yes and often from your first day back. You become an Australian tax resident the moment your life re-centres here, and you don’t need to tick every box to get there. Meeting any one of the ATO’s four tests is enough.
Why does Australian tax residency matter for the tax you pay?
Because residency decides the scope of what Australia taxes. The ATO is clear: residents are taxed on worldwide income, while foreign residents are taxed only on Australian-sourced income.
For a returning founder with an overseas salary, foreign dividends, or a business interest abroad, that distinction can be worth tens of thousands of dollars. It also shapes how you structure your Australian company, which we’ll come back to.
What are the four ATO residency tests for expats?
You only need to meet one of these four tests to be treated as an Australian tax resident. Here’s what each one checks and what it means if you’re returning to run a business:
Test | What it checks | What it means for a returning business owner |
|---|---|---|
Resides test | Whether you “live” in Australia, your ties, family, work, and intentions | The main, common-sense test. If your life is now based here, you’re likely a resident. |
Domicile test | Whether Australia is your permanent home, unless your permanent place of abode is genuinely overseas | The classic expat trap. You can be taxed as a resident even while abroad if you never really cut ties. |
183-day test | Whether you’re in Australia for 183 days or more in the income year | Not a simple count. You can be over 183 days and still a non-resident, or under it and still a resident. |
Superannuation test | Whether you’re an Australian government employee in the CSS or PSS schemes | Very narrow. It almost certainly doesn’t apply to founders or contractors. |
How does the 183-day rule for Australian tax residency actually work?
If you’re physically present in Australia for 183 days or more in the income year, continuously or on and off, you’re presumed to be a tax resident, and the ATO counts both your arrival and departure days toward the total
It’s a presumption, not a formula: you can rebut it by showing your usual place of abode is overseas and you don’t intend to settle here.
But here’s what trips up returning expats:
- The day count is only one of four tests, and the others apply independently of it.
- So you can spend well over 183 days in Australia and still be a non-resident, or fewer and still be caught.
A consultant who keeps a family home, local bank accounts, and a plan to stay can be a resident from day one, however, few days have ticked over. So treat 183 days as a useful checkpoint, not the answer.
What is the resides test and how does it decide residency?
The resides test asks whether you actually live in Australia. It’s judged on the overall picture of your life, not any single rule. The ATO weighs factors like:
- Your physical presence here
- Your purpose and intention for being in Australia
- Where your family is based
- Your business and economic ties
- Your social and living arrangements
It’s the primary test and the most fact-heavy.
Take a founder who returns from Hong Kong, signs a lease in Sydney, moves their family back, and starts running their company from an Australian office. Under the resides test, that founder is almost certainly a resident, even before any day count matters, because their life and business have re-centred on Australia.
If that’s you, residency is rarely in doubt. The real work is getting the tax treatment of your overseas income right, and a registered tax agent can confirm your position and keep your lodgements clean.
Most expats don't miscount days, they assume they stopped being residents the day they flew out. Domicile doesn't work that way. Keep a house, accounts, and a plan to return, and you may have been a resident the whole time. Confirm your position before you lodge, not after the ATO asks.
What is the domicile test and how does it affect expats?
The domicile test treats you as a resident if your domicile is in Australia, unless the ATO is satisfied your permanent place of abode is genuinely overseas.
Domicile is your permanent legal home.
- Most Australian-born people keep an Australian domicile unless they take active steps to adopt a “domicile of choice” abroad.
- The ATO applies Taxation Ruling TR 2023/1 to decide where your permanent place of abode really sits.
This is the test that catches expats who never fully cut ties. Picture a contractor who spent three years in Singapore but kept an Australian house, bank accounts, and a plan to come home.
Even while living abroad, they may have stayed an Australian resident under the domicile test, and so been liable for Australian tax on their Singapore income the whole time. The lesson for returning business owners: document your circumstances carefully, because a misjudged position can mean back taxes and penalties.
How is the 183-day test different from the domicile test?
Both tests can turn on where your “place of abode” sits but they set the bar at different heights, and that gap can change the outcome on identical facts:
Aspect | 183-day test | Domicile test |
|---|---|---|
What you must show to be a non-resident | Your usual place of abode is overseas | Your permanent place of abode is overseas |
The bar | Lower, “usual” is easier to establish | Higher, “permanent” demands deeper, lasting ties |
What triggers it | Physical presence more than half the income year | An Australian domicile you haven’t actively replaced |
For a returning IT contractor on a long project, the 183-day count is what can flip you to resident partway through the year. So keep a clear log of every entry and exit date, that record is exactly what an accountant uses to confirm your status and lodge the right return.
Who does the superannuation test apply to?
The superannuation test makes you an Australian tax resident if you’re a government employee contributing to the Commonwealth Superannuation Scheme (CSS) or the Public Sector Superannuation Scheme (PSS).
- It’s a statutory test, so it can deem you a resident even when you don’t live here in the ordinary sense and if you’re a member, your spouse and any children under 16 are treated as residents too.
- For founders and contractors, though, this one almost never applies.
- It doesn’t cover the newer PSSAP scheme, and it doesn’t touch private-sector workers or business owners at all.
So if you’ve spent your career running businesses or contracting rather than in a Commonwealth super scheme, you can set this test aside and focus on the other three.
How Australian tax residency affects your business and worldwide income
Your residency status sets the scope of your Australian tax. As a resident you’re taxed on worldwide income; as a foreign resident, only on Australian-sourced income.
For a returning founder, that’s the difference between
- Australia taxing your overseas consulting fees,
- Foreign dividends
- Rental income, or leaving them alone
Residents can usually claim foreign income tax offsets to reduce double taxation, though those offsets won’t always wipe out the Australian liability entirely.
Residency also touches the capital gains tax discount.
- The 50% CGT discount that residents enjoy is generally lost for assets acquired after 8 May 2012 while you were a foreign resident, with only an apportioned discount for the period you were an Australian resident.
There’s a separate trap on the family home.
- Foreign residents lost the main residence exemption almost entirely for disposals after 30 June 2020. There’s also withholding to watch: since 1 January 2025, a foreign resident selling Australian property has 15% withheld at settlement unless they obtain an ATO clearance certificate.
- If you’re selling around the time you move, all of this can bite at once, so it pays to check the timing and your residency status on the sale date, before you sign.
Residency affects company structure too. If you run a Singapore or Hong Kong head office with an Australian arm, your personal residency interacts with where the company is managed and controlled.
Australian company profits are taxed separately from your personal position, at 25% for base rate entities or 30% otherwise. One thing to watch: the 25% rate needs both of these to be true:
- Aggregated turnover under A$50 million, and
- No more than 80% of income coming from passive sources like dividends, interest, and rent
A holding-style structure can quietly tip you onto the 30% rate, so the two need to be planned together.
Because your personal position and your company’s tax sit side by side, they’re best planned together rather than separately. Sleek’s Australian accounting services cover both, along with bookkeeping and ASIC compliance.
Residency turns on your specific facts, and the wrong call can mean back taxes or amended returns. Confirm your position with a registered tax agent before you act; a Sleek accountant can tell you where you stand.
Resident vs non-resident tax return in Australia: Which one do you lodge?
The return you lodge follows your residency status; residents report worldwide income, foreign residents report only Australian-sourced income. The difference goes beyond what you declare:
| Aspect | Australian resident | Foreign resident |
|---|---|---|
| Income taxed | Worldwide income | Australian-sourced income only |
| Tax-free threshold | Yes (A$18,200) | No |
| 50% CGT discount | Generally available | Reduced or unavailable for foreign-resident periods |
| Foreign income tax offsets | Available | Not applicable |
Deadlines matter here too:
- Registered with a tax agent by 31 October? Your return is generally due by 15 May the following year.
- Self-lodging? The deadline is 31 October.
Getting your residency call right before you lodge is what saves you from amended returns and ATO queries down the track.

Frequently Asked Questions
Does the ATO tax my overseas income once I return to Australia?
If you become an Australian tax resident, the ATO taxes your worldwide income, including overseas salary, dividends, and business profits. If you remain a foreign resident, only your Australian-sourced income is taxed. Residents can usually claim foreign income tax offsets to reduce double taxation, but these won’t always remove the Australian liability completely, so it’s worth confirming your status early.
Do I keep the 50% CGT discount if I sell assets after returning?
It depends on your residency over the ownership period. The 50% CGT discount available to residents can be reduced or unavailable for the time you were a foreign resident, which matters if you sell business assets or property near your move date. Because the apportionment rules are detailed, confirm your specific position with a registered tax agent before you sell rather than after.
Can I be a tax resident if I spend fewer than 183 days in Australia?
Yes. The 183-day count is only one of four tests. The resides test and domicile test apply independently, so if your home, family, business ties, and intentions point to Australia, you can be a resident on far fewer days. The reverse is also true: more than 183 days doesn’t automatically make you a resident if your usual place of abode is genuinely overseas.
