South Australia charges transfer duty (stamp duty) on all residential property purchases using a progressive bracket system — the higher the property price, the higher the effective rate. The calculator above applies the exact 2026 rate schedule from the South Revenue Office.
South Australia abolished stamp duty for first home buyers purchasing new homes. Existing homes still attract the standard rate.If you're not a first home buyer, the standard rates apply from dollar one.
Stamp duty is payable at settlement — your conveyancer or solicitor handles the payment to the revenue office. Budget for it alongside your deposit, building inspection, conveyancing fees, and lender's mortgage insurance if your LVR exceeds 80%.
