CGT Rollover Divorce Australia — How the Tax Deferral Works
CGT Rollover Divorce Australia — How the Tax Deferral Works
Transferring property between separating spouses in Australia would normally trigger capital gains tax. An investment property bought for $500,000 that's now worth $800,000 has a $300,000 capital gain — and the ATO would ordinarily want its share when ownership changes hands. But Subdivision 126-A of the Income Tax Assessment Act 1997 provides automatic rollover relief that defers this liability entirely.
Understanding how this rollover works — and when it doesn't — can save you tens of thousands of dollars or prevent a surprise tax bill years down the track.
How the Rollover Works
When a CGT asset (real estate, shares, business interests) is transferred between spouses or de facto partners because of a relationship breakdown, the transfer is treated as if it happened at the original cost base — not at market value. No capital gains event is triggered at the time of transfer.
The receiving spouse inherits the original cost base and acquisition date. If and when they eventually sell the asset, they'll calculate their capital gain from the original purchase price, not from the value at the time of the divorce transfer.
Example: Sarah and James bought an investment property in 2015 for $600,000. At the time of their divorce settlement in 2026, it's worth $900,000. James transfers the property to Sarah under consent orders. Under the CGT rollover, no capital gain is assessed on the $300,000 increase. Sarah's cost base remains $600,000. If she sells the property in 2030 for $1 million, she'll pay CGT on a $400,000 gain ($1 million minus $600,000).
The Rollover Is Automatic — With Conditions
You don't need to apply for the rollover or elect it on your tax return. It applies automatically when three conditions are met:
- The transfer is between spouses or former de facto partners — this includes same-sex partners
- The transfer occurs because of the breakdown of the relationship — the causal connection must be genuine
- The transfer is made under a formal family law instrument — consent orders, a binding financial agreement, or a court order under the Family Law Act
The third condition is where informal agreements fail. If you transfer property outside of a court order or BFA — a simple private sale or gift between former partners — the rollover doesn't apply, and the transferring party faces an immediate CGT liability.
What Assets Are Covered
The rollover applies to any CGT asset, including:
- Investment properties
- Shares and managed fund units
- Business interests and partnership shares
- Cryptocurrency holdings (classified as CGT assets by the ATO)
- Collectibles above the $500 threshold (art, jewellery, rare items)
- Interests in trusts and companies
The main residence exemption is separate. If the family home qualifies as a CGT-exempt main residence, no CGT applies anyway — the rollover is irrelevant for that asset. The rollover matters most for investment properties, share portfolios, and business interests.

When the Rollover Doesn't Help
The rollover defers CGT — it doesn't eliminate it. The receiving spouse inherits the full latent tax liability. This has important implications for negotiating a fair split:
The asset's "after-tax value" is lower than its market value. If you're receiving an investment property with a $200,000 embedded capital gain, and your marginal tax rate will be 37% when you eventually sell, the latent CGT liability is approximately $37,000 (after the 50% CGT discount for assets held over 12 months). A fair negotiation accounts for this — the property isn't worth its full market value to you because you'll owe tax when you sell.
The receiving party bears all the tax risk. If property values rise substantially after the transfer, the receiving party's eventual CGT liability grows — but that growth was entirely post-settlement. Conversely, if values fall, the receiving party has a smaller gain (or a loss) to deal with.
The 50% CGT Discount
For assets held longer than 12 months, individuals can apply the 50% CGT discount — only half the capital gain is included in taxable income. When the rollover applies, the receiving spouse inherits the original acquisition date. If the asset was originally acquired more than 12 months before the eventual sale, the discount applies to the full gain.
Superannuation and the Rollover
Superannuation splits under Part VIIIB of the Family Law Act are handled through the super splitting regime, not the CGT rollover. There's no CGT event when super is split — the transfer between super accounts isn't a taxable event for either party.
Practical Steps
- Identify all CGT assets in the pool: List every investment property, share parcel, business interest, and other CGT asset with its original cost base and current market value
- Calculate the embedded gain: Market value minus cost base for each asset
- Estimate the latent CGT liability: Apply the relevant marginal tax rate (after the 50% discount for assets held over 12 months) to estimate what the receiving party will eventually owe
- Factor latent CGT into negotiations: When one party receives more CGT-heavy assets, adjust the overall split to account for the deferred tax burden
- Ensure formal instruments are in place: The rollover only works with consent orders or a BFA — never transfer CGT assets informally
