How Stamp Duty Works in South Australia
Stamp duty in South Australia is calculated using 9 progressive brackets, the most granular bracket system of any Australian state. Rates start at 1.0% on the first $12,000 and rise through incremental steps to 5.5% on amounts over $500,000. The detailed bracket structure means duty increases more gradually than in states with fewer, larger brackets.
SA stamp duty is administered by RevenueSA (part of the Department of Treasury and Finance). The duty is payable at settlement or within 60 days of the transaction, whichever comes first. South Australia uses electronic settlements through PEXA, and your conveyancer handles the duty payment as part of the process.
South Australia distinguishes between new and established homes for first home buyers. Since 6 June 2024, first home buyers purchasing a new home receive a full duty exemption with no price cap. First home buyers purchasing an established home receive no concession and pay the standard rates. SA also offers a $15,000 First Home Owner Grant for new-build homes valued up to $650,000, which can be combined with the new-home duty exemption.

Frequently Asked Questions

Do first home buyers get a stamp duty discount in SA?

First home buyers purchasing an established home receive no concession and pay the standard rates. SA also offers a $15,000 First Home Owner Grant for new homes up to $650,000.
Why does SA have 9 stamp duty brackets?
South Australia uses a more granular bracket system than most states, with 9 tiers starting from just $12,000. This creates a smoother escalation of duty compared to states with fewer brackets, meaning the duty increase is more gradual as property values rise.
When is stamp duty payable in South Australia?
SA stamp duty is payable at settlement or within 60 days of the transaction date, whichever comes first. Your conveyancer handles the payment to RevenueSA as part of the settlement process.
What is the SA First Home Owner Grant?
South Australia offers a $15,000 First Home Owner Grant (FHOG) for first home buyers purchasing or building a new home valued up to $650,000. This is a cash grant, not a stamp duty concession — you still pay full stamp duty, but the grant can help offset the cost.
