Capital Gains Tax (CGT) Calculator

Estimate the capital gains tax you would pay when selling an Australian investment property.

How CGT works on property

When you sell an investment property for more than you paid, the profit is a capital gain. This gain is added to your taxable income in the year of sale and taxed at your marginal rate. If you held the property for more than 12 months, you may be eligible for the 50% CGT discount — meaning only half the gain is taxable.

What reduces your capital gain

  • Purchase costs (stamp duty, conveyancing, inspections)
  • Capital improvements made during ownership
  • Selling costs (agent fees, legal fees, marketing)
  • The 50% discount for assets held longer than 12 months

Proposed CGT reforms

Proposals have included reducing the 50% CGT discount to 25% for investment properties. Our calculator lets you toggle this reform scenario to see how it would affect your after-tax profit on sale.
