Many Australians assume their main residence is always CGT-free. That is true while you are an Australian resident for tax purposes. But if you move overseas and become a foreign resident, the rules change significantly — and the tax bill can be substantial.
The rule: no main residence exemption for foreign residents
Since 12 December 2019, if you are a foreign resident at the time of the CGT event (typically the contract date), you generally cannot claim the main residence exemption. This applies even if:
- You lived in the property for years before leaving
- The property was your only home in Australia
- You are an Australian citizen
The exemption is based on your tax residency at the time of sale, not your citizenship or history with the property.
The life events exception
There is a narrow exception. You may still qualify for the main residence exemption if, within six years of becoming a foreign resident, one of these life events occurs:
- Terminal medical condition (you, your spouse, or your child under 18)
- Death of your spouse or child under 18
- Divorce or separation involving the property
- Certain compulsory acquisitions (e.g., government resumption)
If the life events exception does not apply, the full gain is assessable.
The 6-year absence rule does not help
The 6-year absence rule (which allows residents to treat a property as their main residence for up to 6 years while renting it out) still applies — but only if you are an Australian resident for tax purposes at the time of sale. If you have become a foreign resident, this rule does not save you.
Worked example
Sarah bought her Sydney apartment in 2018 for $700,000. She lived in it until 2023, when she took a job in Singapore and became a foreign resident. She sells in 2026 for $1,050,000.
| Item | Amount |
|---|---|
| Sale price | $1,050,000 |
| Cost base | $700,000 |
| Capital gain | $350,000 |
| Main residence exemption | Not available (foreign resident at sale) |
| 50% CGT discount | Not available (non-resident) |
| Taxable capital gain | $350,000 |
| Estimated tax (no other AU income) | $132,850 |
| FRCGW withheld (15% of $1,050,000) | $157,500 |
| Refund of excess withholding | $24,650 |
If Sarah had sold while still an Australian resident, the gain would have been completely exempt under the main residence exemption.
What you can do
Option 1: Sell before you lose residency
If you know you are leaving Australia permanently, consider selling before you become a foreign resident for tax purposes. Tax residency is determined by facts and circumstances, not a single date — consult a tax agent about your specific timeline.
Option 2: Return to Australia before selling
If you return to Australia and re-establish tax residency before the sale, the main residence exemption may apply again. The ATO will look at whether you have genuinely resumed residency, not just visited briefly.
Option 3: Apply for a withholding variation
Even if you cannot avoid CGT, you can reduce the cash-flow impact. Apply for a withholding variation so the buyer withholds your estimated tax liability instead of 15% of the full sale price.
Option 4: Check if you qualify for partial exemption
If you were a resident for part of your ownership period, you may qualify for a partial main residence exemption. The calculation apportions the gain based on days you were eligible vs total ownership days.
Key takeaways
- Foreign residents generally cannot claim the main residence exemption, regardless of how long they lived in the property
- The 6-year absence rule does not apply if you are a foreign resident at the time of sale
- Australian citizenship alone does not preserve the exemption — tax residency is what matters
- Selling before you leave, or returning before you sell, may preserve the exemption
- If you must sell as a non-resident, apply for a FRCGW variation to manage cash flow
