Avoid the Non-Resident Capital Gains Tax Trap
In December 2019, the Australian Federal Parliament passed legislation that fundamentally altered Capital Gains Tax (CGT) rules for Australian expats. Under the Treasury Laws Amendment Act 2019, foreign tax residents generally lose the Main Residence CGT Exemption on Australian residential property when selling while residing overseas.
This means that if you sell your former family home while classified as an Australian non-resident for tax purposes, you may be assessed for CGT on 100% of the capital gain from the date of purchase, without the standard 50% CGT discount.
However, with proper strategic planning, expats can utilize the 'Life Events Exception', re-establish Australian tax residency before signing contract of sale, or structure acquisitions through trust or investment mechanisms that optimize global tax outcomes.

1. How the 2020 Expat CGT Law Operates
Prior to 2020, Australian expats could utilize the '6-year rule' to rent out their former home while living overseas and sell it completely tax-free. Under current law, your tax residency status on the exact date of signing the contract of sale determines your tax liability.
If you sign the sale contract while a foreign tax resident, the entire capital gain—from the day you purchased the property decades ago—becomes fully taxable with zero retrospective main residence relief.
2. The Life Events Exception Criteria
An expat can retain the Main Residence Exemption while living overseas only if they have been non-resident for 6 years or less AND one of the following life events occurs:
- Terminal Medical Condition: The expat or their spouse/child under 18 experiences a terminal medical condition.
- Death: The death of the expat spouse or dependent child.
- Divorce / Relationship Breakdown: Transfer of property resulting from a formal family law settlement or court order.
3. Mortgage Deductibility While Renting Out
While you are living overseas, renting out your Australian property turns it into an income-producing asset. All mortgage interest, management fees, council rates, and building depreciation become 100% tax-deductible against Australian rental income.
Carried-forward tax losses can offset future Australian taxable income upon your return.
