Leaving Australia: When Australian Tax Residency Actually Ends

Ceasing Australian tax residency is a status change, not a paperwork exercise. Someone who books a one-way flight to Singapore or Dubai remains an Australian tax resident until the Australian tests say otherwise — and those tests are older, softer, and more litigated than most departing residents assume. As of 2026, the promised replacement — a bright-line 183-day primary test with a four-factor secondary test — has been consulted on but not enacted. The rules on the books remain the ones the Australian Taxation Office (ATO) has been applying, and arguing about, for decades.

This is a research overview of how residency actually ends: which of the four statutory tests the ATO applies, why the "resides" and "domicile" tests dominate real disputes, how the exit tax under CGT event I1 works alongside the elective deferral choice under CGT event I2, what happens to superannuation on departure, and the patterns behind common ATO residency challenges. Rate and threshold figures are drawn from the Australian data on TaxAtlas; individual circumstances and treaty positions vary, so verify with a qualified Australian tax adviser before acting.

The four residency tests that Australia still applies

Australian tax residency for individuals is determined by four alternative statutory tests. Meeting any one of them makes a person a tax resident under Australian law. To cease residency, a person must fail all four.

1. The resides test (ordinary concepts)

The primary test is whether the person "resides" in Australia within the ordinary meaning of that word. This is a facts-and-circumstances test drawn from case law rather than statute. The ATO's Ruling TR 2023/1 (which replaced TR 98/17) sets out the factors it weighs: physical presence, intention and purpose of presence, family and business ties, maintenance and location of assets, social and living arrangements, and the frequency, regularity and duration of visits.

No single factor decides. Someone who leaves Australia but keeps a family home available, a spouse and school-age children resident, private health cover retained and Australian club memberships active will often still "reside" in Australia by ordinary concepts — even after physically moving offshore.

2. The domicile test

The domicile test says a person is an Australian resident if their domicile is in Australia, unless the Commissioner is satisfied their "permanent place of abode" is outside Australia. Two elements matter:

• Domicile is a common-law concept — normally domicile of origin until a domicile of choice is validly acquired elsewhere, which requires both physical presence in the new jurisdiction and an intention to remain indefinitely.
• Permanent place of abode is not the same as domicile. It is a place the person has adopted as home for the indefinite future, assessed by physical presence, the nature and duration of accommodation, employment, family arrangements, and abandonment of the Australian home.

The Full Federal Court's 2019 decision in Harding v Commissioner of Taxation reshaped this test in a taxpayer-favourable direction: the "permanent place of abode" can be a country or town rather than a specific dwelling, and a person living in successive rentals in Bahrain qualified as having a permanent place of abode outside Australia despite unresolved arrangements back home.

3. The 183-day test

A person who is physically present in Australia for more than 183 days in an income year is a resident under this test, unless the Commissioner is satisfied that (a) the person's "usual place of abode" is outside Australia and (b) they do not intend to take up residence in Australia. The 183-day threshold works in favour of establishing residency — it is not, as sometimes assumed, a safe-harbour ceiling for departing residents.

4. The Commonwealth superannuation test

Membership of certain Commonwealth government superannuation schemes (principally CSS and PSS) makes the person, their spouse, and their children under 16 Australian residents for tax purposes regardless of physical location. This is a narrow catch that primarily affects Commonwealth public servants and their families.

The proposed bright-line reforms — where they stand in 2026

A cleaner statutory framework has been proposed but is not yet law as of 2026. The Board of Taxation's 2019 review recommended replacing the four-test framework with:

• A primary 183-day test: a person who spends 183 days or more in Australia in the income year is a resident.
• A secondary factor test for individuals who spend 45 to 182 days in Australia, based on four objective criteria — right to reside permanently, Australian accommodation, Australian family, and Australian economic ties.

The May 2021 Budget adopted the recommendation in principle, and Treasury issued a consultation paper in 2023. As of early 2026, no bill has been enacted — the reform sits on the "announced but not delivered" list. Departing residents are still assessed against the four current tests, and the ATO continues to publish guidance under that framework. Verify the status with an adviser before relying on either version, particularly if timing a departure around a rumoured commencement date.

CGT event I1 and the deferral choice under I2

When Australian tax residency ends, Income Tax Assessment Act 1997 section 104-160 (CGT event I1) treats the individual as having disposed of every CGT asset at market value on the day residency ends — the classic "deemed disposal" mechanism covered in the exit taxes guide. The resulting notional gain (or loss) is included in the final residency-year Australian return.

Several important carve-outs and elections apply:

• Taxable Australian property (TAP) is excluded. Direct interests in Australian real property, indirect interests in Australian real property held through entities, and business assets of an Australian permanent establishment stay within the Australian CGT net regardless of residency, so they are not caught by the deemed disposal on exit.
• The 50% CGT discount applies to the deemed gain on assets held for more than 12 months, mirroring the standard Australian CGT treatment for individuals.
• Pre-CGT assets (acquired before 20 September 1985) are outside the CGT net entirely.

The elective deferral — often called the "I2 choice" — is the feature most misunderstood on departure. A departing resident can elect under section 104-165 to treat each non-TAP CGT asset as if it were taxable Australian property. The election defers CGT event I1 on that asset. In exchange, the asset stays within the Australian CGT net until it is actually sold, at which point CGT event I2 applies and the gain (measured back to the original cost base) is taxable in Australia. Foreign tax credits, treaty relief, and the CGT discount on the eventual gain may still be available.

Practical trade-offs of the choice:

• Defer if: the asset is illiquid or hard to value, the departing resident has no cash to fund the deemed-disposal tax, or the expected sale is many years away in a jurisdiction with its own step-up rules.
• Take the deemed disposal if: the asset is expected to appreciate substantially post-departure in a lower-tax jurisdiction, the CGT discount and current cost base are attractive, or continued Australian CGT exposure creates ongoing filing friction.

The election is made per asset, on the return for the year residency ends. There is no partial election within a single asset. Cost-base records are essential — the ATO will expect them at eventual disposal, which can be a decade or more later.

Superannuation on departure

Superannuation is treated separately from ordinary CGT assets on exit. Key points:

• Australian super funds remain Australian super funds once the member becomes a non-resident. Accumulation-phase balances continue in the 15% concessional environment. Contributions during non-residency are constrained by fund rules and, for self-managed super funds (SMSFs), by the "central management and control" and "active member" residency tests — failing these can convert an SMSF into a non-complying fund, which is materially worse.
• Temporary residents leaving Australia can access their super under the Departing Australia Superannuation Payment (DASP) framework, taxed at 35% on the taxable component (65% for former Working Holiday Maker visa holders). This does not apply to Australian citizens or permanent residents.
• Australian citizens and permanent residents keep super preserved to the usual release rules — non-residency does not force a payout. Distributions in retirement may still be subject to the destination country's rules; the Australia–US treaty, for example, gives the US taxing rights over some superannuation payments to US residents, and treatment in the UAE and Singapore depends on remittance and local classification rules.

For SMSFs specifically, the practical response before departure is usually either (a) rolling the balance into a large APRA-regulated fund to eliminate the residency-of-fund risk, or (b) appointing an Australian-resident enduring power of attorney with genuine decision-making authority. Getting this wrong can cost roughly the top marginal rate applied to the fund's assets at transition — a material haircut that warrants specialist review before the residency line is crossed.

Common ATO residency disputes

The pattern of disputed matters is remarkably consistent. Cases where the ATO successfully argues continued residency post-departure typically feature at least one of:

• Family staying behind — spouse and school-age children remaining in the Australian family home is close to fatal for a "permanent place of abode outside Australia" argument.
• The Australian home kept available — retaining an unrented family home suggests the person could return at any time.
• Short assignment length — assignments under about two years often fail on both the resides and domicile tests.
• Hotel-and-serviced-apartment lifestyle offshore — post-Harding, a settled offshore town or country can be a permanent place of abode without a permanent lease, but transient accommodation still weakens the argument.
• Continuing Australian economic anchor — active Australian business, ongoing employment on Australian payroll, cars registered in Australia, private health cover retained, and membership of Australian clubs and professional bodies.

Two useful reference points from recent case law: Harding (2019) established that a permanent place of abode can be a locality rather than a specific dwelling; Pike v FCT (2019) confirmed that under the Australia–Thailand treaty tie-breaker, a taxpayer with vital interests centred in Thailand was Thai-resident even where domestic-law tests were arguably met. Treaties matter: where the destination country is a treaty partner, the tie-breaker rules can override the four Australian tests and resolve residency in the taxpayer's favour.

What changes on arrival in Singapore or the UAE

The tax profile of the destination country determines whether the exit-tax cost is offset by ongoing savings. For the two most common departure destinations from Australia:

Singapore's rate compression matters: the 24% top rate (from Year of Assessment 2024) is higher than the 22% headline departing residents may remember from prior years. The Not Ordinarily Resident (NOR) scheme, historically the sweetener for senior expat hires, closed to new entrants after YA 2024 — that concession is no longer available to arrivals in 2026. The UAE remains a zero personal income tax jurisdiction, with the caveat that corporate tax at 9% applies to business profits above AED 375,000 and a 15% Domestic Minimum Top-up Tax now applies to in-scope multinational groups; see the Singapore vs Dubai comparison for a more granular breakdown.

Departing residents should also confirm the destination's tax residency thresholds and any inbound-regime steps before the CGT event I1 clock starts. Both Singapore and the UAE apply their own 183-day residency-certificate rules, which affect treaty access. See the tax residency guide and territorial vs worldwide taxation primer for background.

Practical sequencing before departure

Because CGT event I1 fires the moment residency ends, sequencing matters:

• Realise or elect deliberately: decide asset-by-asset which appreciated holdings to sell before departure (locking in the pre-departure cost base and CGT discount) and which to elect into the I2 deferral.
• Resolve SMSF residency: either roll to an APRA-regulated fund or lock in an Australian-resident decision-maker before crossing the residency line.
• Close or reassign Australian economic ties that would otherwise anchor the resides and domicile tests — rent out or sell the family home, cancel private health cover, resign from Australian director positions or professional memberships that require Australian residency.
• Document intention behaviourally: the ATO's evidentiary bar is behavioural, not just declared. Contemporaneous records of the destination lease, employment contract, family relocation, and abandonment of Australian arrangements support the residency-cessation date.
• Check treaty positions: where the destination country has a comprehensive tax treaty with Australia, tie-breaker rules can be decisive in dual-resident years. Verify with a qualified adviser familiar with both jurisdictions.

None of this is legal or tax advice, and rules and administrative practice can change. As of 2026 the four-test framework and CGT event I1/I2 architecture remain in force, but the proposed bright-line reforms could alter the analysis in future income years. Verify current rules with a registered Australian tax adviser before acting.
