Main residence exemption for foreign residents
If you are a foreign resident when you sell your Australian former home, you generally can’t claim the main residence exemption unless a narrow life events test is met. This rule applies to disposals after 30 June 2020, so the relevant period and years are before and after this date.
The exemption is intended to align the treatment of capital gains for foreign residents with that of direct owners, clarifying the policy intent behind these provisions. Only certain capital gains are included in the exemption, while gains arising outside the qualifying period are not included.
To understand the complexities, you need to know how the rules differentiate between assets and the classification of taxable property for expats. Expats who left Australia and later sell should model the cash impact before exchange. ATO updated its guidance in 2025 and has examples.
Note: There are important exceptions and recent changes to these rules, so check the latest ATO guidance before making decisions.
Changing residency and “deemed disposal”
When you stop being an Australian resident, a CGT event is triggered and you are taken to have disposed of your CGT assets at market value at that time, except for taxable Australian property.
This is called deemed disposal. When a foreign resident stops being an Australian resident for tax purposes, they are deemed to have disposed of their non-taxable Australian property assets at market value (such as shares and overseas property). The relevant period or years for the deemed disposal is the time up to the date you cease residency, which affects how gains are calculated.
A taxpayer makes a capital gain or loss at the time the CGT event is triggered, unless an election is made to defer it. You may choose to disregard the gain or loss, but assets for which you choose deferral are treated as taxable Australian property going forward.
Capital gains tax is deferred if a foreign resident elects to not treat their assets as disposed of when they cease to be a resident. The choice has long-term implications for future exits, estate planning and UK interaction, so we run scenario modelling before you depart or return.
Note: There are important exceptions and planning points, such as the treatment of assets acquired during different years or periods of residency.
