How it works
Each Australian state and territory sets its own stamp duty brackets and marginal rates. We apply simplified standard-rate brackets for an owner-occupier purchase.
Concessions (first home buyer, off-the-plan, pensioner), foreign buyer surcharges and investor differences are not included. Use this for a quick estimate, then confirm with your state revenue office.
