Property Stamp Duty Calculator

Use our stamp duty calculator above to know the cost of stamp duty on a house purchase in your state/territory.

To use the calculator, select the state you’re buying in. First Homeowner Grants differ from state to state, as do the regulations around stamp duty, so we’ve provided links to the individual state and territory regulatory bodies for further reading. If you're in NSW, The NSW Government is proposing changes to Stamp Duty. ​​​​​​
