Published 30 March 2026 · 9 min read

Taking your career overseas as an Australian expat is an exciting adventure — but it comes with complex tax obligations that can catch you off guard if you're not prepared. Whether you're working in London, Singapore, Dubai, or New York, understanding how the Australian Taxation Office (ATO) treats your foreign income is essential for staying compliant and avoiding unexpected tax bills.

This comprehensive guide explains everything Australian expats need to know about tax for FY 2025-26, including how to determine your residency status, what income you must report, and strategies to legally minimise your Australian tax liability. Use our income tax calculator to estimate your obligations based on your specific circumstances.

Are You an Australian Resident or Foreign Resident for Tax Purposes?

The most important question for any Australian expat is your tax residency status. This isn't the same as your citizenship or permanent residency — it's a separate determination made by the ATO based on your living arrangements, intentions, and ties to Australia. Getting this wrong can be extremely costly.

The ATO applies four statutory tests to determine tax residency. The primary "resides" test examines whether you actually live in Australia on a permanent or indefinite basis. Factors include where you sleep, where your family lives, where you work, and your overall intention. The 183-day test presumes you're a resident if you're physically present in Australia for more than half the financial year, unless your usual place of abode is overseas.

Many Australian expats are surprised to learn they remain Australian tax residents despite living overseas for years. If you've kept your Australian home, your family remains in Australia, and you're working overseas on a fixed-term contract with plans to return, you're likely still a resident for tax purposes. This means you must declare your worldwide income to the ATO.

Conversely, if you've sold your Australian property, moved your family overseas, established a new permanent home, and severed most ties to Australia, you may be a foreign resident for tax purposes. Our take-home pay calculator can help you understand the financial implications of different residency scenarios.

Tax Obligations for Australian Resident Expats

If you're an Australian tax resident living overseas, you're taxed on your worldwide income. This means you must declare all income you earn from foreign employment, investments, rental properties, and any other sources to the ATO, even if you've already paid tax in your host country.

The good news is that Australia has Double Tax Agreements (DTAs) with over 40 countries, including all major expat destinations like the UK, USA, Canada, Singapore, Hong Kong, UAE, and most of Europe. These agreements typically prevent you from being taxed twice on the same income by allowing you to claim a Foreign Income Tax Offset (FITO) for tax paid overseas.

Australian resident expats pay tax at the same progressive rates as residents living in Australia. For FY 2025-26, the rates are: 0% on income up to $18,200, 16% on $18,201 to $45,000, 30% on $45,001 to $135,000, 37% on $135,001 to $190,000, and 45% on income above $190,000. You also pay the 2% Medicare Levy on your taxable income.

If your foreign employer doesn't withhold Australian tax, you may need to make Pay As You Go (PAYG) instalments throughout the year to avoid a large tax bill at lodgement time. The ATO can estimate your tax liability and request quarterly payments based on your previous year's return.

Tax Obligations for Foreign Resident Expats

If you're a foreign resident for tax purposes, your Australian tax obligations change significantly. As a foreign resident, you only pay tax on income that has an Australian source. Foreign income is not taxable in Australia, which can result in substantial tax savings if you're living in a low-tax or tax-free jurisdiction.

However, foreign residents face higher tax rates on Australian income. You pay 32.5% from the first dollar (no tax-free threshold), 37% on income between $135,001 and $190,000, and 45% above $190,000. You also cannot claim the Low Income Tax Offset or several other offsets available to residents.

One major advantage of foreign resident status is that you're exempt from the Medicare Levy. Since you're not eligible for Australia's public healthcare system, you don't pay the 2% levy. This exemption applies automatically — you don't need to apply for it.

If you have HECS-HELP debt, your obligations change when you become a foreign resident. While you're not required to make compulsory repayments through the PAYG system, you must notify the ATO of your overseas income and may need to make repayments based on your worldwide income if it exceeds the threshold.

Expat Tax Comparison: Resident vs Foreign Resident

To understand the financial impact of your residency status, let's compare the tax liability for an Australian expat earning $120,000 per year, assuming all income is foreign-sourced and no foreign tax is payable (for example, working in a tax-free jurisdiction like Dubai).

This example illustrates why many Australian expats aim to become foreign residents — the potential tax savings can be substantial, especially if you're working in a low-tax jurisdiction. However, becoming a foreign resident requires genuinely severing ties with Australia, which isn't always practical or desirable.

If you have Australian-sourced income (such as rental property), the comparison changes. Let's look at the same $120,000 income but assume it's from Australian employment or investments:

*Resident tax includes 2% Medicare Levy. LITO may reduce tax for incomes below $66,667.
**Foreign resident tax excludes Medicare Levy (exempt). No tax offsets available.

Tax Planning Strategies for Australian Expats

Effective tax planning can save Australian expats thousands of dollars each year. The key is understanding your residency status, utilising available concessions, and timing your income and deductions strategically.

If you're planning to leave Australia, consider the timing carefully. Departing early in the financial year means more of your income for that year may be taxed at non-resident rates if you become a foreign resident. If you expect to remain an Australian resident while working overseas, ensure you claim all available deductions, including work-related expenses, self-education costs, and any expenses incurred in earning your foreign income.

Australian expats should also be aware of the temporary repatriation rules. If you return to Australia temporarily (for example, for a holiday or short-term work), your foreign residency status may not change if you haven't re-established Australian residency. However, if your stay extends or you resume living here, your status could revert to resident, affecting your worldwide income obligations.

For expats with Australian rental properties, careful planning is essential. As a non-resident, you're taxed on rental income at higher rates, though you can still claim deductions for property expenses, depreciation, and interest. If you're considering selling your Australian property, be aware that non-residents face additional capital gains tax restrictions and may lose access to the 50% CGT discount for assets acquired after 8 May 2012.

Superannuation Considerations for Expats

Your superannuation remains an important consideration even when working overseas. If you're still an Australian tax resident, your employer (whether Australian or foreign) may not be required to make super contributions, but you can make voluntary contributions to maintain your balance.

If you become a foreign resident, your existing super remains in Australia and continues to be taxed at concessional rates. You generally cannot access your super until you meet a condition of release (such as reaching preservation age), even if you're living overseas. However, if you permanently depart Australia and are a temporary resident (not an Australian or New Zealand citizen or permanent resident), you may be eligible to claim your super as a Departing Australia Superannuation Payment (DASP).

Australian citizens and permanent residents who move overseas indefinitely generally cannot access their super until retirement age, regardless of where they live. This is an important consideration when planning your overseas move and ongoing financial arrangements.
