Frequently Asked Questions
Is stamp duty the same in every state?
No. Each state and territory sets its own rates, thresholds, and first-home buyer concessions.
Does the price include GST?
Duty is usually on the dutiable value of the property interest — check your contract and conveyancer.
Are grants included?
This calculator estimates duty. First Home Owner Grants are separate state schemes.
Is this legally binding?
No — estimates only. Your state revenue office or conveyancer confirms the amount payable.
