If the property has been your main place of residence you will not need to pay tax when you sell your property. Homes are exempt from Capital Gains Tax (CGT). If you are selling an investment property or a second home, you will need to pay tax. CGT may also apply if you've rented part of your property out, you use it for business or it's on more than 2 hectares of land. For a full list of CGT assets and exemptions visit the ATO website.
