What is a CGT event?
When you dispose of an asset that is subject to capital gains tax (CGT), it is called a CGT event. This is the point at which you make a capital gain or loss.
Common disposals that will trigger a CGT event include:
- selling an asset
- trading, exchanging or swapping assets
- loss or destruction of an asset or creating contractual or other rights (this is known as an involuntary disposal).
The type of CGT event that applies to your situation may affect:
- the time when the CGT event happens
- how to calculate your capital gain or loss.

Sale or disposal of asset
Selling or disposing of an asset will trigger a CGT event and you may have a capital gain or capital loss.
If there is a contract of sale, the CGT event happens when you enter into the contract. For example, if you sell a house, the CGT event happens on the date of the contract, not when you settle.
If there is no contract of sale, the CGT event is usually when you stop being the asset's owner. For example, if you sell shares, the CGT event happens on the date of sale.
Example: contract of sale
In June 2023, Sue entered into a contract to sell land she owned.
The contract settled in October 2023.
Sue made the capital gain in the 2022–23 income year (the year she entered into the contract), not the 2023–24 income year (the year settlement took place).
End of exampleYour capital gain or loss for an asset is usually the selling price less the original cost and certain other costs associated with acquiring, holding and disposing of the asset. Find out how to calculate your CGT.
Loss, theft or destruction of asset
If your CGT asset is lost, stolen or destroyed:
- the CGT event happens when you first receive compensation for the loss, theft or destruction
- your capital gain is the amount of compensation less the asset’s original cost.
If you do not receive any compensation, the CGT event happens when the loss is discovered or the destruction occurred.
If you replace the asset with a similar asset, you may be able to defer (or 'roll over') your capital gain until another CGT event happens, such as selling the replacement asset. See Involuntary disposal of a CGT asset for more information.
Example: insurance policy
Laurie's rental property was destroyed by fire in June 2023.
He received compensation under an insurance policy in October 2023.
The CGT event happened in October 2023 when he received the compensation.
End of example
Example: no compensation or insurance policy
Christine owned a rental property that was damaged by floods in May 2023.
The local council deemed the property uninhabitable in August 2023. The property was demolished in November 2023 and Christine did not receive any compensation.
The CGT event happened in May 2023 when the damage happened.

All CGT events are listed below.
If more than one CGT event happens, you apply the rules for the one that best matches your situation.
