What is CGT rollover relief?
CGT rollover relief is a tax rule that allows you to defer paying capital gains tax when you transfer a CGT asset under certain conditions. Instead of being hit with a tax bill straight away, the CGT is deferred until a later event, usually when you eventually sell or dispose of the asset that replaced it.
This relief exists because some transfers, like business restructures, relationship breakdowns, or replacing an asset, don’t genuinely change who controls or benefits from the asset. So rather than taxing you immediately, the rules allow the cost base and history of the original asset to carry over, ensuring fairness and consistency.

When does CGT rollover relief apply?
CGT rollover relief applies when a CGT asset is transferred or replaced in a way that doesn’t genuinely change who benefits from the asset.
It commonly applies in the following situations:
- Business restructures or transfers into a new entity
- Small business active asset rollovers
- Involuntary disposal of assets
- Marriage or relationship breakdowns
- Corporate demergers
- Transfers between related parties or entities

CGT rollover relief for small businesses
Small business owners often rely on CGT rollover relief to restructure or reinvest without facing an immediate capital gains tax bill.
Here are the key situations where rollover relief may apply:
- Small business restructure rollover – Lets you move active assets into a different structure (such as a company or trust) while keeping the same underlying economic ownership in place.
- Replacement asset rollover – Allows you to defer a capital gain when you sell an active asset and use the proceeds to acquire a new active asset.
- Changes in ownership between business partners – Helps when partners adjust their ownership interests without altering the core business structure.
- Transfers between related small business entities – Supports asset transfers within a family group or related entities where the business ownership effectively remains the same.
- Transitioning to a more protective structure – Common when sole traders shift their business into a company or trust for future growth or risk management.

CGT rollover relief and property transfers
CGT rollover relief can also apply to certain property transfers, especially when the transfer doesn’t represent a true change in economic ownership.
Here are the key situations where rollover relief may be available for property:
- Transfers involving small business property – Rollover relief may apply when an active business property is transferred as part of a restructure.
- Involuntary disposals of property – If a property is destroyed, damaged, or compulsorily acquired, you may defer CGT by purchasing a replacement property.
- Property transfers during a relationship breakdown – Transfers under court orders or binding financial agreements generally qualify for automatic rollover relief.
- Property moved between related entities – Some transfers within a family group or between related businesses may qualify if the underlying ownership doesn’t change.
- Residential property linked to a business structure – Certain CGT assets tied to a business (e.g., mixed-use or rental properties) may be eligible under specific rollover rules.
[tip_box]
Before transferring any property, check whether the transfer changes the underlying ownership of the asset. A quick review with an adviser can prevent costly mistakes. Be sure to watch out for potential stamp duty/transfer duty charges that occur on property restructures. Refer to the state revenue office websites for more information on this.

How replacement assets and reinvestment relief work
When you dispose of a CGT asset and acquire a replacement asset, certain CGT rollover rules allow you to defer the capital gain, but only if strict timing and eligibility conditions are met. This relief is commonly used when an asset is involuntarily lost, destroyed, or compulsorily acquired, but it can also apply in other specific scenarios.
[section_inner_1 id="identify-the-cgt-event" format="overview"]
Identify the CGT event
First, work out exactly what happened to the original asset. Was it sold, destroyed, or acquired by a government authority? You’ll also need the date of the CGT event, as the timing rules for rollover relief are based on this.
[/section_inner_1]
[section_inner_1 id="confirm-that-rollover-relief-is-available" format="overview"]
Confirm that rollover relief is available
Next, check whether your situation falls under one of the ATO’s rollover provisions for replacement assets. If the event doesn’t qualify under the legislation, you won’t be able to use CGT rollover relief, even if you buy a new asset.
[/section_inner_1]
[section_inner_1 id="calculate-the-capital-gain" format="overview"]
Calculate the capital gain
Then, calculate the capital gain that would arise if rollover relief did not apply. This amount doesn’t disappear; it’s simply deferred and effectively attaches to the replacement asset.
[/section_inner_1]
[section_inner_1 id="choose-and-acquire-an-eligible-replacement-asset" format="overview"]
Choose and acquire an eligible replacement asset
You must acquire a replacement asset that meets the ATO’s criteria, for example:
- It’s used for the same or a similar purpose
- It’s of a similar type or function
- It’s acquired in your name or in the right entity
If the replacement asset doesn’t meet these tests, CGT rollover relief won’t apply.
[/section_inner_1]
[section_inner_1 id="meet-the-timing-requirements" format="overview"]
Meet the timing requirements
In most cases, the replacement asset must be acquired within a specified timeframe, typically within 12 months of the CGT event. If you need more time, you can request an extension from the ATO, but this is not automatic.
[/section_inner_1]
[section_inner_1 id="apply-the-deferred-gain-to-the-new-asset" format="overview"]
Apply the deferred gain to the new asset
When rollover relief is available, the deferred capital gain becomes part of the tax history of the replacement asset. You don’t pay CGT now, but you may pay it later when you eventually sell or dispose of the replacement asset.
[/section_inner_1]
[section_inner_1 id="keep-thorough-records" format="overview"]
Keep thorough records
Finally, make sure you retain detailed documentation. Contracts, valuations, dates, and evidence of how the replacement asset is used. Good records make it much easier to support your rollover position if the ATO ever reviews your tax return.

[section id="what-to-consider-before-choosing-rollover-relief" format="mixed"]
What to consider before choosing rollover relief
Choosing CGT rollover relief isn’t always straightforward. Before deciding to defer a capital gain, it’s important to understand the long-term implications and whether the relief genuinely benefits your situation.
Eligibility requirements
- Check whether your transaction falls under an ATO-approved rollover category.
- Confirm that the asset type, entity, and timing meet the legislative rules.
Nature of the asset
- Determine whether the original asset and replacement asset are CGT assets.
- Some assets (such as pre-CGT assets) have specific rules.
Replacement asset requirements
- Ensure the replacement asset is acquired within the ATO’s required timeframe.
- Confirm it will be used for the same or a related purpose.
- Check that the same taxpayer or relevant entity holds the asset.
Deferred capital gain mechanics
- Understand how the deferred gain will attach to the replacement asset’s cost base.
- Recognise that disposing of the replacement asset later will trigger both the deferred and new capital gains.
Future business or structural changes
- Planned restructures, sales, or changes in ownership may limit the usefulness of rollover relief.
- Entities expecting significant growth may face a larger later CGT bill.
Record-keeping and compliance
- Maintain detailed records of CGT events, proceeds, costs, valuations, and acquisition dates.
- Ensure all documentation aligns with ATO expectations.
