SA stamp duty rates
RevenueSA charges stamp duty on a sliding scale that rises with the property's value. These are the rates the calculator uses, as RevenueSA publishes them.
| Dutiable value | Duty |
|---|---|
| Does not exceed $12,000 | $1.00 for every $100 or part of $100 |

| Exceeds $300,000 but not $500,000 | $11,330 plus $5.00 for every $100 or part of $100 over $300,000 |

How stamp duty is calculated in South Australia
Find the band the dutiable value falls in and apply its rate. A $700,000 purchase at the general rate falls in the “Exceeds $500,000” band ($21,330 plus $5.50 for every $100 or part of $100 over $500,000):
$21,330 + $5.50 × 2,000 (the number of $100 steps above $500,000) = $32,330
The dutiable value is the price you pay, or the property's market value if that is higher. Concessions then reduce or remove the duty, and a foreign purchaser surcharge is added on top.
First home buyer stamp duty in South Australia
For contracts from 13 February 2025, eligible first home buyers get full stamp duty relief, regardless of the property's value, on a new home, an off-the-plan apartment or vacant land to build their home on. There is no relief on an established home, and the relief doesn't reduce the foreign ownership surcharge.
RevenueSA says that to qualify:
- each applicant must be a natural person aged at least 18
- at least one applicant must be an Australian citizen or permanent resident, or a New Zealand citizen living permanently in Australia on a Special Category visa
- you and your spouse or domestic partner must never have held a relevant interest in residential property in Australia (contracts from 13 February 2025), and must not have received first home buyer duty relief in any state
- every applicant must live in the home for at least 6 continuous months, starting within 12 months of settlement (for land, within 12 months of being able to live in the new home or 36 months of settlement, whichever is first).
Seniors downsizing stamp duty relief
For contracts from 25 March 2026, people aged 60 and over who sell their home in South Australia and downsize to a property with a smaller land size can get stamp duty relief on the new property. It must be a newly built home, an off-the-plan apartment or vacant land to build on. Relief is full up to $2 million for a new home or apartment and $1.2 million for land, and phases out by $2.1 million and $1.3 million. The sale must happen within 12 months before or after settlement of the new property. The calculator doesn't model it.
Foreign ownership surcharge
Foreign persons, including foreign companies and trusts, pay a foreign ownership surcharge of 7% of the value of the interest they acquire in residential land, on top of stamp duty and at the same time. On a $700,000 investment that is $49,000, for a total of $81,330. If only one buyer is a foreign person, the surcharge applies to their share.
When is stamp duty due in South Australia?
Stamp duty becomes payable at settlement, when the property transfers to your name. Your conveyancer usually pays it and lodges any first home buyer relief application for you. Land Services SA charges separate lodgement and transfer fees, which its property transfer fee calculator works out.
RevenueSA notes that stamp duty applies only to residential and primary production land: land used for other purposes ("qualifying land") isn't subject to it.
What the calculator leaves out
- Land titles registration and transfer fees, which are charged separately.
- Off-the-plan, pensioner and other special concessions, and purchases split between eligible and ineligible buyers.
- Mixed-use, commercial and primary production property.
