How Capital Gains Tax Works in Australia

When you sell an asset for more than you paid for it, you make a capital gain. This gain is added to your assessable income and taxed at your marginal rate.

  • 50% CGT Discount: Available for assets held 12+ months (individuals only)
  • Cost Base: Purchase price + acquisition costs + capital improvements
  • Net Capital Gain: Total gains minus total capital losses
  • Medicare Levy: 2% applies to taxable income including net capital gains
