How Capital Gains Tax Works
Capital gains tax (CGT) applies when you sell an asset — such as property, shares, or cryptocurrency — for more than you paid. In Australia, capital gains are added to your taxable income and taxed at your marginal tax rate.
If you hold the asset for at least 12 months, you may be eligible for the 50% CGT discount, which halves the taxable gain. This discount applies to Australian resident individuals and superannuation funds (at a reduced rate), but not to companies.
Your cost base includes the purchase price plus incidental costs like stamp duty, conveyancing fees, and capital improvements. Selling costs such as agent commissions and legal fees are also deducted.
