What Are CGT Events and When Is Capital Gains Tax Triggered?
Capital Gains Tax (CGT) is triggered when a CGT event occurs. These events are specific transactions or situations that result in a capital gain or loss. In Australia, CGT events go beyond just selling an asset—they include gifting property, receiving compensation, or even changing the use of an asset.
If you’re wondering whether something you’ve done with an asset means you’ll pay tax, the key is whether a CGT event has happened. And that’s what we’ll cover in this article: the different types of CGT events, when they apply, and what that means for your tax return.
Whether you’re a property investor, share trader, small business owner, or just a regular Australian selling a family heirloom, this guide will walk you through CGT events clearly and simply.
Why CGT Events Matter
Understanding CGT events is crucial because they determine when and how you calculate a capital gain or loss. These calculations feed directly into your tax return. Some CGT events trigger tax immediately, while others can defer tax or even be disregarded entirely.
There are over 50 different CGT events in Australian tax law, but they fall into a few broad categories. Once you understand the structure, navigating CGT becomes much easier.
The Main Categories of CGT Events
CGT Event A1: Disposal of an Asset
This is the most common CGT event, it occurs when you sell or dispose of an asset. This could include:
- Selling a rental property
- Selling shares or units in a managed fund
- Gifting an asset to someone
- Transferring an asset to a trust or company
The timing of the CGT event is generally when you enter into the contract, not when settlement occurs.
Trigger Example: You sell your investment property on 15 June 2024 (contract date), with settlement on 30 July 2024. The CGT event is triggered on 15 June 2024.
CGT Event B1: Granting an Asset
Occurs when you grant someone possession of an asset but still legally own it. This is less common for individuals but can arise in business structuring.
Trigger Example: You grant someone use of a property under a long-term lease.
CGT Event C1: Loss or Destruction of an Asset
If your asset is destroyed (e.g. in a fire or natural disaster), this can trigger a CGT event. You may receive compensation, which affects the calculation of your gain or loss.
Trigger Example: Your rental property is destroyed in a bushfire and you receive an insurance payout.
CGT Event D1: Creating Contractual or Other Rights
This event applies when you create rights, such as agreeing not to do something (a restrictive covenant), or granting a licence.
Trigger Example: You grant a license to another party to use your business brand.
CGT Event E1-E8: Trust-Related Events
These events involve transfers to and from trusts. They’re particularly relevant to family trusts, unit trusts, and SMSFs.
Trigger Example (E1): You transfer an asset into a discretionary trust.
Trigger Example (E4): A unit trust distributes assets to a beneficiary.
CGT Event F1-F5: Lease Events
These events deal with lease rights and obligations.
Trigger Example: You assign a lease to another party.
CGT Event G3: Liquidation Distributions
Applies when a company distributes assets during a liquidation.
Trigger Example: You hold shares in a company that goes into liquidation and you receive a final distribution.
CGT Event K6: Disposal of Pre-CGT Shares or Trust Interests
This event can apply if pre-CGT assets (owned before 20 September 1985) are bundled with post-CGT assets in a transaction.
Trigger Example: You sell shares acquired before CGT existed, but the company holds significant post-CGT assets.
Special Cases Where CGT Is Not Triggered
Main Residence Exemption
If you sell your main residence, you may be entirely exempt from CGT, as long as it was your home for the full ownership period and no part of it was used to earn income.
Personal Use Assets
Capital gains from personal-use assets (like furniture or cars) are typically disregarded unless they were acquired for more than $10,000.
Pre-CGT Assets
If you acquired an asset before 20 September 1985, it’s usually exempt from CGT.
Small Business CGT Concessions
There are generous concessions available for business owners, including the 15-year exemption, 50% active asset reduction, retirement exemption, and rollover for reinvestment.
When Is CGT Paid?
Capital Gains Tax isn’t a separate tax, it’s part of your income tax. You calculate your net capital gain (capital gains minus capital losses and any available discounts or concessions) and include it in your annual tax return.
Key Dates:
- Individuals: CGT is reported and paid when you lodge your tax return, usually by 31 October (or later if using a registered tax agent).
- Companies and Trusts: Different lodgement deadlines apply, depending on structure.
How to Reduce or Defer CGT
Apply the 50% CGT Discount
If you’ve held an asset for more than 12 months and you’re an individual or trust, you can reduce the gain by 50%.
Use Capital Losses
You can offset capital gains with capital losses from the current year or prior years.
Rollover Relief
In some situations, you can defer CGT until a later event, such as when assets are compulsorily acquired or replaced.
FAQs About CGT Events
Do I pay CGT when I inherit an asset?
No CGT is triggered when you inherit an asset. But when you later sell it, CGT may apply depending on how the deceased originally acquired it and how you used it.
Do all asset sales trigger CGT?
No. Assets like your main home, cars, or depreciating assets used solely for business may be exempt or subject to other tax rules.
What happens if I give an asset to family?
Gifting an asset is treated the same as selling it at market value for CGT purposes.
Wrapping Up: Know Your CGT Events
Capital Gains Tax doesn’t just apply when you sell an asset, it applies when a CGT event occurs. These events are at the heart of how the ATO determines when and how much tax is payable.
Whether you’re managing investments, passing wealth through a trust, or simply making plans for retirement, recognising CGT events early can help you plan smarter and avoid surprises at tax time.
If you’re ever unsure, especially with more complex assets or events, seek advice from a tax professional who can help you navigate the fine print.
