Detailed Explanation

Capital Gains Tax (CGT) in Australia is levied on the profit (capital gain) made when you sell or dispose of an asset that has increased in value. CGT applies to assets acquired after 20 September 1985, including shares, investment properties, business assets, and collectibles. Your main residence (family home) is generally CGT-exempt under the main residence exemption.

For the 2026/27 financial year, if you hold an asset for at least 12 months before selling, Australian resident individuals, trusts, and partnerships qualify for a 50% CGT discount. This means only half the capital gain is added to your assessable income and taxed at your marginal rate. The discount makes long-term investing significantly more tax-efficient. Note: From 1 July 2027, proposed changes will replace the 50% discount with inflation indexation and a 30% minimum tax rate, but these changes don't apply to 2026/27.

Real-World Example If Olivia bought shares for $50,000 and sells them 18 months later for $80,000, her capital gain is $30,000. With the 50% CGT discount (held >12 months), only $15,000 is added to her assessable income. If her marginal tax rate is 32.5%, she pays $4,875 in CGT ($15,000 × 32.5%). Without the discount, she'd pay $9,750 ($30,000 × 32.5%).
