Capital Gains Tax and Divorce in Australia: CGT Rollover Relief Explained
Capital Gains Tax and Divorce in Australia: CGT Rollover Relief Explained
When you transfer an investment property, shares, or business assets to your ex-spouse as part of a divorce settlement, the ATO doesn't treat it as a taxable sale — as long as the transfer is done properly. Under Subdivision 126-A of the Income Tax Assessment Act 1997, separating couples get automatic CGT rollover relief. But "deferred" is not the same as "eliminated," and the rules have hard boundaries that can trigger unexpected tax bills.
How the CGT Rollover Works
When an asset is transferred between separating spouses under a court order or Binding Financial Agreement, the capital gain or loss is completely disregarded at the time of transfer. No tax event is triggered.
Instead, the receiving spouse inherits the original asset's cost base and acquisition date. They step into the transferor's tax shoes entirely. When they eventually sell the asset — potentially years later — they're liable for the full capital gain accrued since the original purchase, not just the gain since the transfer.
Example: You bought an investment property in 2015 for $500,000. At divorce in 2026, it's worth $800,000. You transfer it to your ex-spouse under Consent Orders. No CGT is triggered. But when your ex sells it in 2030 for $900,000, they owe CGT on the $400,000 gain (from the $500,000 original cost base), not the $100,000 gain since they received it.
This matters enormously for settlement negotiations. The spouse receiving a highly appreciated asset is inheriting a hidden tax liability that the asset's face value doesn't reflect.
The Critical Boundary: Spouse-to-Spouse Only
The Full Federal Court in Ellison v Sandini Pty Ltd established that CGT rollover relief is strictly confined to transfers made directly to a spouse or former spouse.
Transfers directed to:
- A company controlled by the receiving spouse
- A private trust or family trust
- A self-managed super fund
Do not qualify for the rollover — even if executed under a Family Court order. In these cases, the transferring entity is assessed for immediate capital gains tax. The receiving party may also face additional tax consequences under Division 7A.
If your settlement involves transferring assets to a structure rather than directly to your ex, get specific tax advice before the orders are made.
The Main Residence Exemption
The family home is generally exempt from CGT under the main residence exemption. But divorce complicates this because the exemption depends on the property being your "main residence" — and after separation, at least one party has moved out.
The six-year rule provides a buffer: if you move out of your home but continue to own it, you can treat it as your main residence for up to six years if it's rented out, or indefinitely if it's left vacant. The condition is that you don't claim another property as your main residence during that time.
Where this gets complicated:
- If both parties buy new homes and claim the main residence exemption on their new properties, the original home loses its exemption from the date the second exemption was claimed
- If one party stays in the home and the other moves out, only the party staying maintains an automatic exemption
- If the property is transferred as part of the settlement and later sold, the six-year clock resets from the date the receiving spouse moves out (if they do)

Tax Filing After Divorce
Beyond CGT, several tax administration tasks need attention:
Update your relationship status with the ATO through MyGov. This affects your Medicare levy surcharge assessment, private health insurance rebate tier, and family tax benefit calculations.
Review your tax return filing. If you were previously assessed as a couple for certain benefits, your individual income now determines your thresholds. This can increase or decrease your tax obligations depending on your individual income relative to the former combined household income.
Check your PAYG withholding. If your employer was withholding based on claiming the tax-free threshold with a dependent spouse, your withholding rate may need adjustment.
Spousal maintenance payments are tax-deductible for the payer and assessable income for the recipient under Australian tax law. Lump-sum property settlements are not — they're capital, not income.
What to Get Right in the Settlement
The CGT implications should inform how assets are divided, not just the face value. Two assets worth the same on paper can have very different after-tax values:
- A property bought recently with a small capital gain has a lower embedded tax liability
- A property bought decades ago with massive appreciation carries a much larger deferred CGT bill
- Shares in a small business may have complex cost base calculations that affect the real value
Factor in the deferred tax when agreeing to asset splits — or get an accountant to model the after-tax value of each asset before the orders are finalised.
The NSW After-Divorce Checklist covers the tax implications of property transfers and includes a CGT tracking worksheet to help you understand the real after-tax value of assets in your settlement.
