📢 2026 Budget update – changes from 1 July 2027. The 50% CGT discount for individuals, trusts and partnerships will be replaced with cost base indexation and a 30% minimum tax rate on capital gains – but only for gains that accrue after 1 July 2027. Gains up to that date keep the current rules. These changes are now law. This calculator uses the current rules for the 2025–26 and 2026–27 income years. Read the full update →
Calculate your capital gains tax
How capital gains tax works
A capital gain is generally the sale price, less selling costs, less what the asset cost you (including buying costs). The net capital gain is added to your taxable income and taxed at your marginal rate.
If you are an individual or a trust beneficiary and you owned the asset for at least 12 months, you can usually reduce the gain by 50%. Complying super funds receive a one-third discount, and companies receive no discount.
Ways to legally reduce CGT
- Hold assets for more than 12 months where possible
- Include all eligible costs in your cost base, such as stamp duty, legal fees and capital improvements
- Use capital losses to offset gains
- Check whether the main residence exemption applies
- Plan the timing of the sale with your accountant

Does this calculator include depreciation adjustments?
