How Stamp Duty Works in South Australia
Rates last checked against RevenueSA in October 2026.
Stamp duty is a one-off government charge on buying property. In South Australia it is officially called conveyance duty and it is collected by RevenueSA. You pay it around settlement, and your conveyancer or solicitor normally arranges the payment for you.
The duty is worked out on the dutiable value of the property, which is the higher of the purchase price and the market value. If GST applies to the sale (for example on some new builds), duty is charged on the GST-inclusive amount.
South Australia uses a marginal scale with nine bands. As the value climbs, each additional slice of value is charged at a higher rate, similar to how income tax brackets work. Owner-occupiers and investors pay the same rates.
SA Stamp Duty Rates for Property
These are the RevenueSA conveyance duty rates the calculator above uses. Each rate applies to every $100, or part of $100, in that band.
| Property Value | Duty |
|---|---|
| Up to $12,000 | $1 for every $100 |
| $12,001 to $30,000 | $120 plus $2 for every $100 over $12,000 |
| $30,001 to $50,000 | $480 plus $3 for every $100 over $30,000 |
| $50,001 to $100,000 | $1,080 plus $3.50 for every $100 over $50,000 |
| $100,001 to $200,000 | $2,830 plus $4 for every $100 over $100,000 |
| $200,001 to $250,000 | $6,830 plus $4.25 for every $100 over $200,000 |
| $250,001 to $300,000 | $8,955 plus $4.75 for every $100 over $250,000 |
| $300,001 to $500,000 | $11,330 plus $5 for every $100 over $300,000 |
| Over $500,000 | $21,330 plus $5.50 for every $100 over $500,000 |
Rates can change with each State Budget, so confirm the current figures on the RevenueSA rates page before you rely on any estimate.
Worked Example: Stamp Duty on a $600,000 Home in SA
Here is how the duty on a $600,000 established home is built, one band at a time. The same slice-by-slice method runs behind the calculator.
| Value Band | Rate | Value in Band | Duty |
|---|---|---|---|
| $0 to $12,000 | $1.00 per $100 | $12,000 | $120 |
| $12,000 to $30,000 | $2.00 per $100 | $18,000 | $360 |
| $30,000 to $50,000 | $3.00 per $100 | $20,000 | $600 |
| $50,000 to $100,000 | $3.50 per $100 | $50,000 | $1,750 |
| $100,000 to $200,000 | $4.00 per $100 | $100,000 | $4,000 |
| $200,000 to $250,000 | $4.25 per $100 | $50,000 | $2,125 |
| $250,000 to $300,000 | $4.75 per $100 | $50,000 | $2,375 |
| $300,000 to $500,000 | $5.00 per $100 | $200,000 | $10,000 |
| $500,000 to $600,000 | $5.50 per $100 | $100,000 | $5,500 |
| Total stamp duty | $26,830 | ||
That works out to about 4.47% of the purchase price. Because the top band is the most expensive, every extra $10,000 on a price above $500,000 adds $550 in duty.

First Home Buyers: Stamp Duty Relief in South Australia
South Australia does not give first home buyers a discount on established homes. It does, however, offer full stamp duty relief on certain new purchases, and since the 2024-25 State Budget there is no value cap on that relief for contracts entered into on or after 6 June 2024.
- A new home
- An off-the-plan apartment
- Vacant land to build your home on
- A house-and-land package (contract to build)
- An established home
- An established home you plan to knock down and rebuild
- An investment property or holiday home
To keep the relief you must live in the property as your principal place of residence for a continuous period of at least six months, starting within the timeframe RevenueSA sets. Companies and trusts are generally not eligible. Eligible buyers of a new home may also be able to claim the First Home Owner Grant, which is a separate payment you apply for separately. Read the RevenueSA first home buyer page to check your own eligibility before signing a contract.
In the calculator, choose First home buyer and set the property type to a new home or land to see the relief applied.
Foreign Buyers: The 7% Surcharge
Foreign persons and foreign trusts that acquire residential land in South Australia pay a foreign ownership surcharge of 7% of the value of the interest acquired. It is charged in addition to normal stamp duty and is paid at the same time.
Example: $600,000 residential property bought by a foreign person
- Standard stamp duty: $26,830
- Foreign ownership surcharge (7% of $600,000): $42,000
- Total duty payable: $68,830
Select Foreign buyer in the calculator to see the surcharge added. Whether you count as a foreign person is a legal question, so check with RevenueSA or a conveyancer if you are unsure.
Other Stamp Duty Relief to Look Into
RevenueSA also lists seniors downsizing stamp duty relief. The 2026-27 State Budget formalised a measure aimed at South Australians aged 60 and over who sell their existing home and buy a smaller new or off-the-plan home. The eligibility rules, value limits and application steps are set out in RevenueSA guidance, so read them on the RevenueSA website rather than relying on a summary. The calculator on this page does not model this relief.
Relief is something you apply for. It is not applied automatically, so ask your conveyancer to lodge the right application with RevenueSA.
Other Costs When Buying a Home in SA
Stamp duty is only one part of the upfront bill. Plan for these as well:
To see what your repayments could look like once you factor in these costs, try our mortgage calculator, and use our savings calculator to plan how long it will take to save the deposit and duty.
How This Calculator Works
The calculator follows the same steps RevenueSA uses:
Dutiable value = higher of (purchase price, market value)
Duty = band base + rate x (each $100 or part of $100 over the band start)
Total = standard duty - first home relief (if eligible) + 7% surcharge (if foreign)
The band table in the results panel shows how each slice of value adds up, and the rows always sum to the total.
