How capital gains tax works in Australia

Capital gains tax in Australia is the tax you pay on profits from disposing of assets such as property, shares and crypto assets. The short answer for beginners: according to the Australian Taxation Office (ATO), it is not a separate tax at all. A capital gain is added to your income in your tax return and taxed at your individual income tax rate.

The tax is triggered by a CGT event, which generally happens when you stop being the owner of an asset, for example when you sell it. A capital gain increases the tax you need to pay, while a capital loss can be used to reduce capital gains in the same year or carried forward to future years.

The ATO describes CGT as the tax you pay on profits from disposing of assets including investments. Because it is part of your income tax, there is no separate CGT rate. Instead, your net capital gain for the year is included in your assessable income and taxed alongside your wages, interest and other income.

The key moment is the CGT event. The ATO explains that if you sell an asset and there is no contract of sale, the CGT event happens at the time of sale. If there is a contract to sell, the CGT event happens on the date of the contract, not when you settle, which is how property sales usually work. If an asset is lost or destroyed, the CGT event happens when you first receive an insurance payment or other compensation, or, if there is none, when the loss occurred or was discovered.

The ATO gives a simple example. Maree buys some shares for $5,000, owns them for 6 months and sells them for $5,500. She has no other capital gains or losses. She declares a capital gain of $500 in her tax return and pays tax on this gain at her individual income tax rate. Because she held the shares for less than 12 months, the CGT discount does not apply.

Since a gain increases the tax you owe, the ATO suggests you may want to work out how much tax you'll owe and set aside funds to cover it. Record keeping matters too: you need the date you acquired an asset, what you paid and related costs so you can work out the cost base later.

Readers evaluating capital gains tax in Australia should separate marketing claims from the actual rule text that governs their account or product. When two summaries disagree, the governing document or statute wins. If a rule depends on your age, filing status, or income band, re-check it when any of those facts change. Life events quietly move people across thresholds they last reviewed years earlier.

Which assets are subject to CGT, and which are exempt?

According to the ATO, most property is subject to CGT, including vacant land, business premises, rental properties, holiday houses and hobby farms. CGT also applies to shares, units and similar investments when a CGT event happens, including exchange traded funds (ETFs) and units received from a distribution reinvestment plan. Crypto assets held as investments are covered, and so are intangible assets such as leases, goodwill, licences and contractual rights, and foreign currency.

Personal use assets, such as boats, furniture, electrical goods and household items, are treated differently. A capital gain on a personal use asset is subject to CGT only if it cost you more than $10,000 to acquire, and capital losses on personal use assets are ignored. Collectables such as artwork, jewellery, antiques, coins and stamps are subject to CGT unless you acquired the collectable for $500 or less, and a capital loss on a collectable can only be deducted against capital gains from collectables.

Several assets are exempt. The ATO lists assets acquired before 20 September 1985, your main residence, and cars and motorcycles. A car is defined as a motor vehicle that carries a load of less than 1 tonne and fewer than 9 passengers. Depreciating assets used solely for taxable purposes, such as business equipment and items in a rental property, are outside CGT, as are gambling and competition winnings and certain compensation payments.

The main residence exemption has limits. CGT may apply if you rent out part of your home, use it for business, if it is on more than 2 hectares of land, or if you are a foreign resident who doesn't satisfy the life events test when the CGT event happens.

A useful habit is to write down your goal, time horizon, and cash buffer before you change any election related to capital gains tax in Australia. Decisions made during a stressful week are the ones people reverse later at a cost. Educational explainers like this one cannot replace personalized advice for complex situations such as divorce orders, inherited accounts, or cross-border tax residency. Escalate those cases to a qualified professional.

How the 50% CGT discount works

When you sell or otherwise dispose of an asset, you can reduce your capital gain by 50% if you owned the asset for at least 12 months and you are an Australian resident for tax purposes. When counting the 12 months, the ATO says you exclude the day of acquisition and the day of the CGT event.

There are exclusions. The full discount can't be used for capital gains made by foreign or temporary residents after 8 May 2012, although an apportioned discount may be available if you had a period of Australian residency while you owned the asset. If your home was first used for rental or business less than 12 months before you disposed of it, you can't use the discount. Companies can't use the CGT discount at all, while Australian trusts can discount a gain by 50% and complying super funds by 33.33%.

If you have owned an asset since before 21 September 1999, you can choose to index its cost for inflation instead, but the ATO notes that in most cases the discount gives a better result. There is also an additional discount of up to 10% for resident individuals who provide affordable rental housing to people on low to moderate incomes, which increases the discount to up to 60%.

The ATO also notes that CGT changes announced in the 2026-27 Federal Budget don't apply to Tax Time 2026, so check the ATO's reform page before relying on these rules for later years.

Capital losses and putting it all together

Order matters. The ATO says that if you have any capital losses from other assets, you must subtract these from your capital gains before applying the discount. Only then do you reduce the remaining gain on an eligible asset by 50% and report that amount in your income tax return.

A capital loss you can't use this year is not wasted: you can offset it against capital gains in future years. The ATO stresses that it's important to include losses in your tax return so they are recorded. Remember the special rules, though: losses on personal use assets are ignored, and collectable losses can only offset collectable gains.

A practical routine for beginners is to keep purchase records from day one, note whether each asset is likely to be held for more than 12 months, track any losses, and estimate the tax before you sell so the cash is ready at tax time.
