Australian tax residency: more than one test, and easy to get wrong

Unlike some countries with a single, relatively clear-cut residency test, Australian tax residency for individuals is assessed against several different tests, and meeting any one of them can be enough to make you an Australian tax resident — which means being taxed on worldwide income, similar to UK residents. The main tests include the "resides" test (an ordinary-meaning assessment of whether you reside in Australia, looking at factors like physical presence, intention, family, and business/employment ties), the domicile test (whether your domicile is in Australia and you don't have a permanent place of abode outside Australia), and the 183-day test (broadly, whether you've been in Australia for 183 days or more in the income year).

The practical difficulty for many Australian expats is the domicile test in particular: an Australian domicile doesn't automatically change just because you've moved abroad, and the question of whether you have a "permanent place of abode" outside Australia has been the subject of significant case law and ATO guidance, with outcomes that can be genuinely difficult to predict from general principles alone. There have also been proposals over recent years to reform and simplify Australia's individual tax residency rules (including a proposed bright-line day-count test), though as of any given point the current law — not a proposal — is what applies, which is exactly why checking the current position with a registered tax agent matters.

If you're a non-resident for Australian tax purposes

If you successfully establish non-resident status, the headline change is similar to the UK position: you generally move from being taxed on worldwide income to being taxed only on Australian-source income. However, there's an important practical difference for non-residents: the tax-free threshold that applies to Australian residents generally does not apply to non-residents, meaning Australian-source income (such as rental income from an Australian property) can be taxed from the first dollar at non-resident rates, which are also structured differently from resident rates. This is a common surprise for new expats who assume non-residence is purely beneficial — for Australian-source income specifically, it can mean a higher effective tax rate on that income than you'd have paid as a resident, even though your foreign (UAE) income is no longer taxed at all.

Australian income and assets that commonly remain in scope

Australian rental property

If you keep an investment property in Australia while living in the UAE, the rental income remains taxable in Australia as Australian-source income, and as discussed above, non-resident tax rates (without the resident tax-free threshold) typically apply. You'll generally still need to lodge an Australian tax return each year reporting this income. It's also worth being aware that the main residence exemption from capital gains tax — which many Australians rely on when eventually selling a home — has been significantly restricted for foreign residents in recent years, to the point where non-residents can lose access to the exemption entirely for a property sold while non-resident, even if it was their home for years beforehand. This is a high-stakes area for anyone considering selling an Australian property while living abroad, and timing (selling before leaving, or re-establishing residency before selling, where genuinely applicable) can matter enormously — this is a case where advice well before a sale is far more valuable than advice after.

Superannuation

Superannuation is one of the most common areas of confusion for Australian expats. A few general points: existing super balances generally remain in your fund and continue to be managed under Australian super rules regardless of where you live; if you're employed by an Australian employer while working overseas, super guarantee obligations may or may not apply depending on the arrangement; and if you're employed by a non-Australian employer (as most UAE-based roles would be), compulsory super contributions generally don't apply, though you can typically still make voluntary contributions subject to the usual contribution caps and rules. Whether voluntary super contributions make sense while you're a non-resident UAE-based expat depends on your broader retirement planning, preservation age, and intentions about returning to Australia — it's a genuinely individual question rather than a blanket recommendation.

HECS/HELP debt

If you have an outstanding HECS/HELP debt, Australian rules require expats earning above a certain threshold to make repayments based on their worldwide income, even while living and working overseas — this is a notable difference from how the UK and many other countries treat student loan debt for non-residents. This generally requires lodging a worldwide income return or non-lodgment advice each year specifically for HECS/HELP purposes, even if you have no other Australian tax obligations. This obligation is genuinely easy to overlook precisely because it applies regardless of residency status, and penalties for non-compliance can apply — so this is one item every Australian expat with a HECS/HELP balance should specifically check, regardless of how settled or temporary their UAE move feels.

Australian bank interest and investments

Interest on Australian bank accounts and dividends from Australian shares held by non-residents are generally subject to non-resident withholding tax, deducted at source by the bank or company — which for many types of income, finalises your Australian tax obligation on that income without needing to be included in a tax return. The withholding rate can depend on the type of income and any double tax agreement between Australia and the country you're resident in — notably, Australia and the UAE have a double taxation agreement, and its specific provisions are worth checking with an adviser if you hold meaningful Australian investments.

Practical steps before and after moving to the UAE

1. Before you leave: get a residency assessment from a registered tax agent based on your specific plans (employer, contract length, family arrangements, whether you'll keep an Australian home) — this is the single highest-value piece of advice for most Australian expats, given how fact-dependent the residency tests are.
2. If you have an Australian investment property and might sell it while overseas, get advice on the main residence exemption implications before you become a non-resident, not after you've listed the property.
3. If you have a HECS/HELP debt, set up a system to track and report worldwide income annually as required, regardless of your broader residency position.
4. Notify the ATO of your move and update your address details — and keep records supporting your residency position (departure date, overseas employment contract, overseas address, family arrangements) in case it's ever reviewed.
5. Review your superannuation strategy — including whether to make voluntary contributions while overseas, and whether your fund's insurance arrangements (life, TPD, income protection often bundled with super) remain appropriate or even valid while you're living overseas, which is a commonly overlooked detail.
6. If you hold Australian bank accounts or investments, confirm with your bank/broker that your account has been correctly updated to reflect non-resident status for withholding tax purposes.

How this fits into your wider UAE financial plan

As with the UK expat tax position, the UAE's tax-free salary environment sits alongside, not instead of, your Australian tax position on Australian-source income and HECS/HELP obligations. The single highest-leverage action for most Australian expats is getting a proper residency assessment before or shortly after moving — because so much else (whether your UAE salary is taxed, what rate applies to any Australian rental income, whether the main residence CGT exemption is at risk) flows from that determination.
