Leaving Australia Without a Surprise CGT Bill: A Practical Residency and Asset-Timing Guide

Why departure is a tax event to plan carefully

Moving overseas does not automatically end Australian tax obligations. The ATO explains that residency is assessed using several tests, including the resides test, domicile test, 183-day test and Commonwealth superannuation fund test. The primary question is whether you continue to reside in Australia according to ordinary concepts, but the other tests can also apply.

A person leaving Australia should document the facts supporting their position, including:

• The date they left Australia and the expected duration of the overseas stay.
• Whether they established a permanent home overseas.
• Whether they retained a home, spouse, dependants, business or substantial economic connections in Australia.
• Whether they intend to return and, if so, when and under what circumstances.

CGT consequences when residency changes

When an individual stops being an Australian tax resident, a CGT event can occur for CGT assets that are not taxable Australian property. The ATO’s guidance explains that the taxpayer may be treated as disposing of those assets at market value when residency changes. An alternative election may allow the taxpayer not to trigger that deemed disposal immediately; however, the non-taxable-Australian-property assets can then become taxable Australian property for future purposes.

This means departure timing can matter for shares, managed investments, cryptocurrency and other assets that have increased in value. Before leaving, prepare a valuation record and retain acquisition documents. A valuation is especially important where the asset is not publicly traded.

The family home and the six-year rule

The main residence exemption has detailed conditions. Renting out a former home does not automatically preserve a full exemption indefinitely. Taxpayers should review the period of occupancy, the date the property became income-producing, whether another property is treated as a main residence, and whether foreign-resident restrictions apply when the property is sold.

Superannuation and temporary residents

Temporary residents may have access to a departing Australia superannuation payment after leaving, subject to eligibility requirements. The tax treatment of the payment depends on the circumstances and the type of visa involved.

Action checklist

1. Run the ATO residency tools and obtain professional advice for ambiguous cases.
2. Record the departure date and evidence of overseas settlement.
3. Inventory all CGT assets and obtain defensible market values.
4. Review the intended treatment of the former Australian home.
5. Check superannuation eligibility before departing and keep visa and employment records.

Residency planning should be completed before departure, because a later return, asset sale or change in family circumstances can alter the analysis.
