Selling a Former Main Residence as an Australian Expat

For many Australians who move overseas, selling the family home isn't always the preferred option. Instead, they often choose to keep the property, either as a rental investment, a place to return to one day, or simply as a long-term asset. Over time, that property may experience substantial capital growth, making it one of their most valuable investments.
Because the property was once their main residence, many Australian expats assume the main residence capital gains tax (CGT) exemption will still apply when they eventually decide to sell. However, this isn't always the case. Depending on your tax residency status and the timing of the sale, the exemption may no longer be available, potentially resulting in a significant CGT liability.
In this blog, we'll explain how the main residence exemption generally works, what changes once you become a foreign resident for Australian tax purposes, and why the timing of a sale can make a substantial difference to the tax outcome.
How the Main Residence Exemption normally works
Under Australian tax law, a capital gain made on the sale of your main residence is generally exempt from capital gains tax (CGT). This is one of the most valuable concessions available to Australian taxpayers, and unlike many other CGT concessions, there is no cap on the size of the gain that can be sheltered.
A well-known extension of this concession is the six-year temporary absence rule. This allows individuals to move out of their home, rent it out, and continue treating it as their main residence for CGT purposes for up to six years, provided they have not nominated another property as their main residence during that time. Genuinely moving back into the property resets the six-year clock, and there is no limit on how many times this can occur.
For an Australian resident taxpayer, these concessions are relatively straightforward. However, the complexity arises once tax residency changes.
The Foreign Resident Rules that change everything for Expats
Since legislative changes took full effect on 30 June 2020, individuals who are foreign residents for tax purposes at the time they sell their property will generally not qualify for the main residence exemption. This is where many Australian expats are caught by surprise.
The key points to understand are:
Your tax residency status at the time of the CGT event is what matters, not how long you lived in the property, and not whether you sell within the six-year window. If you are a foreign resident when you enter into the contract of sale, the exemption is generally denied.
The denial is not partial. Unlike some other CGT concessions (such as the 50% CGT Discount), the exemption cannot be apportioned between periods when the property was your main residence and periods when it was rented out. If the exemption is denied as a foreign resident, the entire capital gain, including any growth that occurred while the property was genuinely your home, is taxable.
There is a narrow exception, known as the life events test. If your period of foreign residency at the time of sale is six years or less, you may still be able to access the exemption, but only if a specific life event occurred during that period, such as a terminal medical condition affecting you, your spouse or your child, the death of your spouse or child, or certain court orders or agreements following a relationship breakdown. However, simply moving back to Australia for unrelated reasons before selling does not satisfy this test.
Withholding tax also applies. Foreign Resident Capital Gains Withholding generally applies to Australian property sales by foreign residents, currently withholding a percentage of 15% of the sale price at settlement unless a variation or exemption is obtained.
Put simply, the main residence exemption and temporary absence rules are two separate questions, and both need to be satisfied. An Expat who sells within six years of moving out may still lose the main residence exemption entirely if they are a foreign resident for tax purposes on the day the contract is signed.
Why Timing the Sale is important when selling a former main residence as an Australian Expat
Timing becomes one of the most powerful planning tools available to Expats. Broadly, there are a few paths worth considering well before selling a former main residence as an Australian Expat:
Selling before you leave, or before you become a foreign resident, so the exemption applies under the ordinary rules.
Re-establishing Australian tax residency before the contract is signed, for Expats who are planning to return to Australia and intend to sell the former home, rather than selling while still classified as a foreign resident.
Understanding the trade-off of selling as a foreign resident, where the gain will generally be taxable in full, at non-resident tax rates, with no access to the 50% CGT discount for the period of foreign residency.
The cost of getting the timing wrong can be significant, potentially resulting in hundreds of thousands of dollars in additional tax. That's why it's important to consider the CGT implications well before a sale is underway. Ideally, this analysis should begin before a contract is signed and, in many cases, before you even leave Australia.
Case Study: Timing the Sale to Preserve the Main Residence ExemptionA couple we worked with relocated overseas for employment in 2021 and rented out their former Australian home while they were living abroad. As they prepared to return to Australia in 2026, they planned to sell the property before the six-year absence period expired and use the sale proceeds to purchase a new family home upon arriving back in Australia. Their circumstances were as follows:
On the surface, they appeared to satisfy the six-year absence rule and be exempt from CGT under the main residence exemption. However, they would still be foreign residents for Australian tax purposes when they intended to exchange contracts. This meant the consequences would be very different from what they expected:
Rather than proceeding with the sale while still overseas, we worked with them on a plan to adjust the timing of their return to Australia. By re-establishing Australian tax residency before entering into the contract of sale, and still selling within the six-year absence period, they were able to qualify for the full main residence exemption. The outcome:
This example highlights one of the most common misconceptions we see among Australian expats. The six-year absence rule is only part of the picture. Your tax residency status at the time you sell is equally important and can determine whether the main residence exemption is available at all. Seeking advice before listing the property, not after a contract has been signed, can make a substantial difference to the final tax outcome. |
Other Considerations for Expats selling a former main residence
A few additional factors are often relevant when selling a former main residence as an Australian Expat:
Downsizer super contributions. Returning Australian Expats aged 55 or over selling an eligible former main residence may still be able to make downsizer contributions of up to $300,000 each into superannuation, subject to meeting the eligibility rules. This can be a useful piece of flexibility, particularly given the general restrictions that otherwise apply to non-concessional contributions.
The upcoming CGT and negative gearing reforms. As covered in our earlier blog on the 2026-27 tax changes for Australian Expats, the main residence exemption itself is not affected by the CGT and negative gearing reforms commencing 1 July 2027. However, if a property is not exempt, whether because of the foreign resident rules or because it has been used as an investment property for longer than the exemption allows, the new indexation and minimum tax rules may apply to gains accruing from that date.
Apportionment where the exemption is only partly available. Where the property was genuinely your main residence for only part of the ownership period, and the property was sold as a resident for tax purposes, the main residence exemption may still be apportioned, with the gain calculated based on the market value of the property when it first began producing income.
Key Takeaways
The main residence exemption is generally unavailable if you are a foreign resident for tax purposes at the time you sell your property, regardless of the six-year absence rule.
A narrow life events test may preserve the exemption for foreign residents of six years or less, but it requires a specific life event, not simply returning to Australia before selling.
Your tax residency status on the date the contract of sale is signed is the critical factor, making the timing of both departure and return dates a genuine planning opportunity.
Downsizer super contributions and the upcoming CGT and negative gearing reforms are both worth factoring into the broader decision.
Conclusion
Selling a former main residence as an Australian Expat is rarely just a property decision; it is a tax decision with a property attached. If you are living overseas and still hold a former main residence in Australia, whether you are still years away from selling or actively planning a return, it is worth reviewing your residency position and your intended sale timeline together, rather than assuming the six-year rule alone will protect you.
