How is capital gains tax calculated in Australia?

CGT = Sale Price minus Cost Base minus Capital Losses, then apply 50% discount if held 12+ months. The net capital gain is added to your income and taxed at your marginal rate.

Do I qualify for the 50% CGT discount?

Yes if you are an individual or trust, held the asset for more than 12 months, and are an Australian tax resident. Super funds get 33.33%. Companies get no discount.
