What is the South Australia stamp duty calculator?

The Stamp Duty Calculator South Australia estimates property transfer duty using the 2026–27 RevenueSA rate bands supplied for this tool. Enter the property’s dutiable value and choose either the general schedule or the eligible first home buyer treatment for a qualifying new home, off-the-plan home or vacant land purchase.

The calculator can help buyers compare properties and plan for an important upfront cost. It does not decide whether a buyer qualifies for relief and does not include registration, conveyancing, lending or inspection expenses.

How the South Australia calculator works

  1. Enter the property’s dutiable value.
  2. Select general rates unless you have confirmed eligibility for the first home buyer relief described below.
  3. The tool finds the matching RevenueSA band and applies its base amount and marginal charge.
  4. The result shows estimated duty and the effective percentage of the entered value.

Worked example: $600,000 established home

A $600,000 purchase under the general schedule is $100,000 above the $500,000 threshold. Start with $21,330, then add $5.50 for each of the 1,000 lots of $100 in the excess. Estimated South Australia stamp duty is $26,830, an effective rate of about 4.47%.

First home buyer stamp duty relief in South Australia

An eligible first home buyer can pay no stamp duty when purchasing a new home, an off-the-plan home or vacant land on which a home will be built. Under the supplied 2026–27 information, there is no property price cap for this relief.

Established homes do not receive this first home buyer relief. Select the zero-duty option only after confirming that the buyer, property type, occupancy and transaction meet every current eligibility requirement. If eligibility is uncertain, use the general-rates result for a more cautious budget.

Important: this calculator provides a general estimate based on the supplied RevenueSA 2026–27 rates. The zero-duty option does not assess eligibility. Confirm the final duty and any relief with RevenueSA or a qualified conveyancer before relying on the result.
