One of the most expensive misconceptions I encounter as a UAE-relocated Australian principal is the assumption that moving to Dubai automatically ends Australian tax residency. It does not. Australian tax residency is determined by Australian law (specifically section 6(1) of the Income Tax Assessment Act 1936), and the Australian Taxation Office applies four residency tests: the resides test, the domicile test, the 183-day test and the Commonwealth superannuation test. An individual is an Australian tax resident if they satisfy any one of them.

Moving to the UAE addresses one of those tests directly. The other two require active planning, documentation and (often) structural changes that need to be made before departure rather than after.

The four ATO residency tests.

The ATO applies the following tests, in order:

  1. The ordinary residence (resides) test. A common-law test of whether the individual 'resides' in Australia, considering factors like physical presence, family ties, accommodation, employment, social and economic connections.
  2. The domicile test. An individual whose domicile (broadly: their permanent home) is in Australia is an Australian tax resident unless the ATO is satisfied their 'permanent place of abode' is elsewhere.
  3. The 183-day test. An individual present in Australia for 183 days or more in a tax year is generally an Australian tax resident unless their 'usual place of abode' is outside Australia and they do not intend to take up residence in Australia.
  4. The Commonwealth superannuation test. Members of certain Commonwealth government superannuation schemes (and their spouses and children under 16) are Australian tax residents wherever they live. Rarely relevant to private-sector expats, but absolute where it applies.

The 183-day test is the simplest to navigate once you are physically out of Australia. The domicile test is where the largest number of relocations come unstuck.

The domicile test — where most Australians get it wrong.

Domicile in Australian tax law is not the same as residency or citizenship. It is the legal concept of the individual's permanent home, and it does not change automatically when you move overseas. To shift domicile from Australia to the UAE, you need to demonstrate an intention to make the UAE your permanent home, supported by evidence.

The ATO considers the following factors when assessing whether your 'permanent place of abode' is outside Australia:

  • The intended and actual length of stay overseas. A short-term assignment (1-2 years) is unlikely to satisfy the test. A move described as 'indefinite' with a 5-10+ year horizon is much stronger.
  • Whether the individual has established a home overseas. Renting an apartment is acceptable; purchasing or long-term-leasing a property is stronger evidence.
  • Whether an Australian residence is maintained. Owning a vacant property in Australia that you visit twice a year is much weaker than selling or genuinely tenanting it on commercial terms.
  • The strength of family, social and business ties to Australia versus the UAE. Family who relocate with the individual significantly strengthens the position.
  • The durability of the overseas arrangements. Employment contracts with multi-year terms, school enrolments for children, drivers' licences and bank accounts in the UAE all count.
The ATO does not look for a single decisive fact. It looks at the cumulative pattern. The Australians who break residency well are the ones who treat the move as a permanent change supported by every available piece of evidence — not a tax-driven re-labelling.

The deemed disposal — and why timing matters.

When an individual ceases to be an Australian tax resident, the Australian tax law treats certain assets as having been disposed of for capital-gains purposes (so-called 'CGT event I1'). This includes most non-Australian-real-property assets the individual owns — including shares in offshore companies, foreign investments, and certain crypto holdings.

The deemed disposal happens at market value as at the date of cessation. The individual can elect to defer the CGT (the asset is treated as remaining Taxable Australian Property until actually disposed of), but the election has trade-offs and must be made deliberately.

For Australians with appreciated offshore assets, the timing of residency cessation can have material CGT consequences. We routinely advise on whether to bring the cessation forward or back to optimise the CGT position, and whether to make the deferral election.

No Australia-UAE tax treaty: plan accordingly.

Australia does not have a comprehensive double tax agreement with the UAE. Australia's tax treaty network simply does not include the UAE, so there are no treaty tie-breaker rules, no treaty-reduced withholding rates and no treaty residency protection to fall back on if the ATO argues you remained an Australian resident. The only bilateral tax instrument between the two countries is a limited agreement covering airline profits, and the Australia-UAE Comprehensive Economic Partnership Agreement, in force since 1 October 2025, is a trade and investment agreement, not an income tax treaty.

The practical consequence: everything rides on domestic law. A UAE Tax Residency Certificate does not unlock treaty benefits against Australia, and a contested year cannot be rescued by a tie-breaker. Australian residency must be broken cleanly under the four ATO tests, with the evidence assembled before departure, because there is no treaty safety net behind them.

What to do before departing Australia.

Six actions distinguish a clean residency cessation from a contested one:

  1. Document intent. A clear, dated written record of the intended permanent relocation — visa-application supporting letter, employer letter, school enrolment, lease, business plan — establishes the foundation for the domicile test.
  2. Address Australian property. Sell, or long-term lease on commercial terms to an unrelated party. Avoid vacant maintained-for-personal-use Australian property.
  3. Close redundant Australian arrangements. Cancel Australian club memberships, professional registrations not required, school enrolments, Medicare cover (subject to its own rules), and other indicia.
  4. Establish UAE indicia. UAE residency visa, Emirates ID, UAE bank account, UAE driving licence, UAE phone number, UAE-based assets, UAE-based employment.
  5. Plan the CGT position. Model the deemed disposal, decide on the deferral election, consider whether to crystallise gains before or after departure.
  6. File the final Australian return correctly. Tick the residency cessation date in the year of departure. Lodge any required additional declarations (e.g. departing-Australian-superannuation considerations).

The UAE side: anchoring residency properly.

The UAE residency side of the equation involves establishing tax residence under UAE rules and obtaining a UAE Tax Residency Certificate for treaty purposes:

  • Day count: 183 days physical presence in the UAE in a 12-month period (or 90 days under specific conditions, with a UAE permanent home and centre of financial / personal interests).
  • Documentation: Emirates ID, residency visa, UAE address proof, UAE tenancy contract or property ownership, UAE bank account, and an annual tax-residency declaration.
  • TRC application: Filed with the UAE Federal Tax Authority, typically issued within 4-6 weeks for individuals who meet the residency tests.

Conclusion.

Australian tax residency does not end the day the flight to Dubai departs. It ends when the ATO is satisfied — based on the cumulative evidence of intent, conduct and arrangements — that the individual's permanent place of abode is no longer Australia. The work of demonstrating that should start before departure, supported by a properly planned cessation strategy and a UAE-side framework that establishes UAE residency cleanly.
