How it works now
There’s no separate capital gains tax: a net capital gain is added to your taxable income for the year you sell. Your gain is what you sold for, less your cost base: the price you paid plus costs such as brokerage, stamp duty and legal fees.
If you’ve held the asset for more than 12 months, individuals and trusts get a 50% discount, so only half the gain is taxed.
Example: a $10,000 gain on shares held for 2 years adds $5,000 to your income. At a 32% rate (30% plus the Medicare levy), that’s $1,600 of tax. Sold within a year, the whole $10,000 would be taxed: $3,200.
- 15% tax rate (17% with the levy) $850 less
- Held 12 months or less: $1,700 Held more than 12 months: $850
- 30% tax rate (32% with the levy) $1,600 less
- Held 12 months or less: $3,200 Held more than 12 months: $1,600
- 37% tax rate (39% with the levy) $1,950 less
- Held 12 months or less: $3,900 Held more than 12 months: $1,950
- 45% tax rate (47% with the levy) $2,350 less
- Held 12 months or less: $4,700 Held more than 12 months: $2,350
Holding for more than 12 months halves the tax at every rate
Assumes the whole gain falls in one tax bracket. A large gain can push part of it into a higher one.
No tax is taken out when you sell, so it’s added to your bill when you lodge your tax return. Set some of the gain aside.
What it applies to
- Shares, ETFs and managed funds, including gains a fund passes on to you.
- Crypto, including swapping one coin for another.
- Investment property and holiday homes.
Your car, and personal items you bought for $10,000 or less, are usually exempt. Keep records of what you paid and any costs for 5 years after you sell.
The change announced for 2027
The May 2026 Budget announced that from 1 July 2027:
- The 50% discount is replaced by indexation: the cost of the asset rises with inflation, so only the real gain is taxed.
- A 30% minimum tax applies to net capital gains.
- Gains made before 1 July 2027 keep the 50% discount.
- Negative gearing on established homes bought after Budget night (12 May 2026) can only be used against residential property income and gains.
Check the ATO’s site for whether these changes have become law, and the final details.
Losses
Capital losses can only be set against capital gains, not other income such as your salary. They come off your gains before the 50% discount is applied, and unused losses carry forward to future years.
Your home
Your main residence is usually exempt. If you rented it out or used it for business, part of the gain may be taxable. If you move out and rent it, you can usually keep treating it as your main residence for up to 6 years, as long as you don’t claim another home as your main residence.
Super
Gains inside super are taxed at up to 15%, or 10% on assets held over a year, and nothing in the retirement phase. See where to invest for how investing in super compares with investing outside it.
