Enter details about your asset purchase and sale to calculate your capital gain or loss and the tax you may need to pay. Assets held for 12 months or more qualify for a 50% discount.
The 50% CGT discount changes from 1 July 2027
The figures on this page apply to disposals before 1 July 2027, under the current 50% CGT discount. From that date the discount is replaced with CPI cost-base indexation plus a 30% minimum tax top-up on capital gains, for individuals and for trusts other than complying superannuation funds. Gains are apportioned either side of the change, not simply switched over.
1 July 2027 is when the change takes effect, per the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (checked 2 August 2026). General information only, not personal tax advice.

Tax rate on capital gain
Good news: You held this asset for 12 months or more, so you qualify for the 50% CGT discount. This reduces your taxable capital gain by $25,000.
Capital Gains Tax applies when you sell an asset for more than you paid for it. The profit (capital gain) is added to your taxable income and taxed at your marginal rate.
CGT applies to most assets including shares, investment properties, cryptocurrency and collectibles. Your main residence is generally exempt from CGT.
