CGT Calculator Australia — Calculate Tax on Asset Sales
Calculate capital gains tax on property shares and investment sales in Australia. See the 50% CGT discount for assets held over 12 months.
Capital gains tax in Australia applies to the profit when you sell an asset for more than you paid for it. The key advantage: assets held for more than 12 months receive a 50% CGT discount meaning only half the gain is added to your taxable income. Your main residence (home you live in) is completely exempt from CGT. Capital losses can be carried forward indefinitely to offset future gains.

Frequently Asked Questions
How much CGT on $100000 profit from shares?
If held over 12 months: 50% discount applies. Taxable gain = $50000. If your other income is $80000 (32.5% marginal rate): CGT = $50000 x 32.5% = $16250. Effective tax rate on the $100000 gain: 16.25%. If held under 12 months: full $100000 is taxable = $32500 at 32.5% rate. The 12-month discount saves $16250.
How to minimize capital gains tax in Australia?
Hold assets over 12 months for the 50% discount. Time sales in low-income years (career breaks sabbaticals) for a lower marginal rate. Harvest losses by selling losing investments to offset gains. Use the main residence exemption — consider living in your investment property for a period. Contribute to super (15% tax on gains inside super versus your marginal rate). Spread large gains across multiple financial years where possible.
Does CGT apply when I sell my home?
Your main residence is fully exempt from CGT. However if you rented it out for a period or used part of it for business a partial CGT liability may apply. The 6-year absence rule allows you to rent out your main residence for up to 6 years without losing the CGT exemption as long as you do not claim another property as your main residence during that time.
