Stamp duty, also known as land transfer duty, is a once-off tax paid upon purchasing a property.
Our calculator will help you calculate stamp duty on owner-occupied homes in South Australia, as well as any first home buyer concessions that may apply.
Stamp duty in South Australia is calculated on a sliding scale based on the property value. The same rates apply to owner-occupiers and investors.
Rates start at $1 per $100 for the first $12,000 and rise to $21,330 plus $5.50 per $100 above $500,000. You can see the full table on the RevenueSA website (revenuesa.sa.gov.au).
If you are a first home buyer buying a new home, you may pay no stamp duty (see below).
The government charges additional fees for land purchases and mortgages.
The transfer fee is charged for registering your interest in the property. In SA, it is based on the property value.
The mortgage registration fee applies if you are buying with a home loan. It is a flat fee of $204 for the 2026-27 financial year.
First home buyers in South Australia can get full stamp duty relief when buying a new home, an off-the-plan apartment, or vacant land to build a new home. There is no property value cap. There is no relief for established homes.
For contracts from 13 February 2025, the relief does not apply to the foreign ownership surcharge, and you are not eligible if you or your partner have previously held an interest in residential property in Australia.
Other eligibility criteria generally include:
At least one applicant must be an Australian citizen or permanent resident
Applicants must be at least 18
Companies and trusts are generally not eligible
See the RevenueSA website for the full rules. Our calculator applies the relief when you tick the first home buyer box, and assumes you are buying a new home.
Yes, South Australia has a foreign purchaser surcharge. This is in addition to standard stamp duty rates. Foreign purchaser duty is calculated as 7% of the property value.
You are not considered a foreign owner if you are any of the following:
In South Australia, if you are a foreign owner jointly purchasing with your non-foreign owner partner, you are still required to pay the 7% surcharge on your part of the property.
If you get Australian PR or become a citizen within 12 months of paying the surcharge, you may be eligible for a refund.
Please note that you may be subject to other costs in addition to this surcharge.
