How stamp duty works in Australia
Stamp duty - officially called transfer duty - is a state government tax paid when you buy property. It is calculated as a percentage of the purchase price or market value, and the amount varies significantly between states and territories. In South Australia, stamp duty on a $600,000 property is approximately $26,830 for a standard purchase.
The biggest variable is concessions. First home buyers in SA pay no stamp duty on an eligible new home, off the plan purchase or vacant land to build a new home, with no value cap for contracts from 6 June 2024. There is no first home buyer concession on established homes in SA, so a first home buyer pays the same duty as anyone else on an established home. If you are buying a new build, you may also qualify for the $15,000 First Home Owner Grant. On a new home the relief can save $20,000 or more, but the eligibility rules are specific (source: RevenueSA).
Stamp duty is typically paid at settlement and must be factored into your upfront costs alongside your deposit, legal fees, and any lenders mortgage insurance. Many first home buyers underestimate these costs and find themselves short at settlement. We help you map out the full picture before you start looking at properties.

What is the First Home Owner Grant in SA?
The SA First Home Owner Grant is a $15,000 one-off payment for eligible buyers of new or substantially renovated homes with no price cap (the previous $650,000 cap was removed in June 2024). It is separate from the stamp duty concession - you may be eligible for both. Lendology helps you apply for both simultaneously.
When is stamp duty paid?
Stamp duty is typically paid at settlement. Your conveyancer will arrange payment on your behalf from the settlement funds. It is important to budget for stamp duty as part of your upfront costs when calculating how much deposit you need.
Can stamp duty be added to the loan?
No - stamp duty cannot be added to the home loan in most cases. It must be paid in cash at settlement. This is why it is critical to factor stamp duty into your deposit savings. Lendology calculates your full upfront cost requirement in your first chat.
