First home buyers in South Australia

Buying in another state?
The calculator covers every state and territory at rates as at October 2026. Some states, including Victoria, Queensland, Western Australia and the ACT, charge less when you're buying a home to live in, which is why it asks what you're buying. It doesn't include first home buyer concessions or foreign buyer surcharges in any state.
