TL;DR
- Foreign residents pay tax at rates starting from 30% on Australian-sourced income with no tax-free threshold – residents enjoy a threshold of AUD 18,200 (2025-26 financial year) before any tax applies [3][4].
- Foreign residents lose the 50% Capital Gains Tax (CGT) discount on Australian assets and face a 15% foreign resident CGT withholding obligation on all property sales.
- Determining your tax residency status is a legal question decided by the ATO’s four tests – not simply where you live or where your passport is from [5].
- Double tax agreement Australia rules and the foreign income tax offset can reduce double taxation, but only if claimed correctly in the right sequence.
- Getting your residency classification wrong compounds across multiple years and can attract penalties, back taxes, and interest.
What Is the Australian Tax Residency Test, and Why Does It Determine Everything?
Tax residency is the foundational question that governs every other aspect of your Australian return. Before the ATO considers your income, your deductions, or your CGT position, it must first determine whether you are a resident or a foreign resident – and the consequences of each classification are fundamentally different [1][2].
The ATO does not rely on a single test. It applies four distinct tests in sequence [5][6]:
- Resides Test: Whether you “reside” in Australia based on your physical presence, intentions, family, and business ties. This is the primary test.
- Domicile Test: Whether your permanent place of abode is in Australia. Critically, merely living overseas does not automatically mean your domicile has shifted.
- 183-Day Test: Whether you were present in Australia for 183 days or more in the income year – relevant for inbound individuals.
- Commonwealth Superannuation Test: Applies specifically to Commonwealth government employees and their spouses.
Most Australian expats are assessed under the Domicile Test after they leave. The ATO’s Taxation Ruling TR 2023/1 confirmed that factors such as where your family lives, whether you maintain a home in Australia, your intention to return, and the durability of your overseas arrangements all feed into this determination [6]. This is not a straightforward checklist – it is a qualitative assessment, and reasonable people can reach different conclusions depending on the evidence available.
How Does Foreign Resident Tax in Australia Actually Differ at the Rate Level?
Once the residency question is settled, the income tax rate structure applied to a foreign resident is materially harsher than what a resident faces. This is the first practical consequence most expats underestimate.
| Feature | Australian Resident | Foreign Resident |
|---|---|---|
| Tax-free threshold (2025-26) | AUD 18,200 | None – every dollar is taxed [3][4] |
| Lowest marginal rate (2025-26) | 16% on income above threshold | 30% from the first dollar [4][5] |
| Low Income Tax Offset (LITO) | Available | Not available |
| Medicare Levy (2025-26) | 2% applies | Exempt (no Medicare entitlement) |
| 50% CGT discount | Available after 12-month hold | Not available [4] |
| Income taxed | Worldwide income | Australian-sourced income only [1][2] |
The removal of the tax-free threshold alone is significant. A foreign resident earning AUD 60,000 in Australian rental income pays considerably more tax than a resident earning the same amount – with no offset at the lower end of the scale [3].
What Is Foreign Resident CGT Withholding, and When Does It Apply?
Building on the rate differences above, the harder practical problem for most expat property owners is what happens when they sell. The foreign resident CGT withholding (FRCGW) regime requires the purchaser of your Australian property to withhold a percentage of the purchase price and remit it directly to the ATO at settlement – regardless of what your actual profit is [4].
Key facts about FRCGW as they currently apply:
- The withholding rate is 15% of the gross sale price (not the gain).
- As of 1 January 2025, the threshold for FRCGW was removed, meaning the 15% withholding now applies to all property sales regardless of value.
- A foreign resident seller must lodge a tax return to reconcile actual CGT liability against the amount withheld.
- If your actual CGT liability is lower than the 15% withheld, a refund can be claimed through lodgment – but only if the return is filed.
- Importantly, foreign residents do not receive the 50% CGT discount that resident sellers access after holding an asset for more than 12 months [4][5].
This combination – no discount plus 15% withholding on gross proceeds – means that expats who have not modelled their CGT position before listing a property can face a cash-flow shortfall at settlement that surprises even financially sophisticated clients.
How Do Double Tax Agreements and the Foreign Income Tax Offset Reduce Double Taxation?
A separate but related concern for Australian expats is the risk of being taxed twice – once in their country of residence and again in Australia on the same Australian-source income. Two mechanisms exist to address this, and neither operates automatically.
Australia has a double tax agreement (DTA) with more than 40 countries [4]. These treaties determine which country has taxing rights over specific categories of income – employment income, dividends, rental income, and capital gains. For a foreign resident with Australian rental income, the DTA between Australia and the country of residence may reduce the Australian withholding tax rate on certain passive income streams. Getting the DTA classification wrong – or failing to invoke it – means paying more tax than the treaty permits.
The foreign income tax offset (FITO) is the complementary mechanism. Where a foreign resident earns income that is taxed both overseas and in Australia, FITO allows a credit for foreign tax paid to be offset against Australian tax liability, subject to ATO rules on calculation and eligibility. The offset does not provide a dollar-for-dollar credit in all cases – the calculation method matters, and applying it incorrectly is one of the most common errors ODIN Tax encounters when reviewing returns prepared by generalist accountants.
What Are the Most Costly Mistakes Foreign Residents Make on Their Australian Tax Returns?
Stepping back from the technical detail, the practical question for most expats is: where do things actually go wrong? Across thousands of non-resident returns, the same errors appear repeatedly [3]:
- Claiming the tax-free threshold when non-resident status applies. This reduces tax payable at lodgment but creates a debt, interest, and potential penalties when the ATO identifies the error.
- Misapplying tax residency. Assuming that living overseas for a full year automatically makes you a non-resident – or conversely, assuming a brief return to Australia flips residency back – leads to returns lodged under the wrong classification entirely.
- Ignoring FRCGW obligations. Sellers who are unaware of the withholding regime either have funds held at settlement unexpectedly or, if incorrectly cleared as a resident, face ATO scrutiny later.
- Failing to lodge at all. Expats who believe they have “no Australian income” often have rental income, interest, or unfranked dividends that require lodgment. Overdue returns accumulate failure-to-lodge penalties.
- Incorrect FITO calculation. Overclaiming or underclaiming the foreign income tax offset affects both the current year liability and, in some cases, the offset carried forward.
