Currently, the amount of CGT you will pay can vary depending on how long you have held the investment. If you own the asset for less than 12 months, you will have to pay 100% of the capital gain at your income tax rate. If you own the asset for longer than 12 months, you will pay tax on 50% of the capital gain. But this discount system is being removed for assets acquired after 1 July 2027 and will be replaced with an inflation linked discounting system, meaning tax will be applied based on the inflation-adjusted value of the asset when it’s sold.
Capital gains are taxed at the same rate as taxable income — i.e. if you earn $135,000 (30% marginal tax bracket) per year and make a taxable capital gain of $50,000, you will pay income tax on $185,000 (37% marginal rate) and your capital gains will be taxed at 37%.
As capital gains make up your taxable income, the taxation applied may also depend on how much other income you earned, and factors like whether you will be subject to the Medicare levy surcharge (i.e. whether you have a suitable level of private health insurance).
From 1 July 2027, a minimum CGT rate of 30% will apply.
