SA stamp duty rates
RevenueSA charges conveyance duty per $100 of value, and part of $100 counts as a full $100. The rate scale was not changed by the 2024–25, 2025–26 or 2026–27 State Budgets.
| Value of the property | Stamp duty |
|---|---|
| Up to $12,000 | $1.00 for every $100 |
| $12,001 – $30,000 | $120 plus $2.00 for every $100 over $12,000 |
| $30,001 – $50,000 | $480 plus $3.00 for every $100 over $30,000 |
| $50,001 – $100,000 | $1,080 plus $3.50 for every $100 over $50,000 |
| $100,001 – $200,000 | $2,830 plus $4.00 for every $100 over $100,000 |
| $200,001 – $250,000 | $6,830 plus $4.25 for every $100 over $200,000 |
| $250,001 – $300,000 | $8,955 plus $4.75 for every $100 over $250,000 |
| $300,001 – $500,000 | $11,330 plus $5.00 for every $100 over $300,000 |
| Over $500,000 | $21,330 plus $5.50 for every $100 over $500,000 |
Since 1 July 2018, South Australia charges conveyance duty only on residential and primary production land, so most commercial property transfers are duty-free.
First home buyer relief
For contracts signed on or after 6 June 2024, eligible first home buyers pay no stamp duty on:
- a new home that has never been lived in or sold as a residence, including a substantially renovated home bought from a developer;
- an off-the-plan apartment;
- a house-and-land package; or
- vacant land on which you will build your home.
There is no property value cap. Relief does not apply to established homes, including knock-down rebuilds. At least one buyer must be an Australian citizen or permanent resident, all buyers must be at least 18, and neither you nor your partner can have lived for 6 months or more in an Australian home you had an interest in. One buyer must live in the home for 6 continuous months, starting within 12 months of settlement (or, for land, within 12 months of the certificate of occupancy or 36 months of settlement, whichever is first).
Seniors downsizing relief from 25 March 2026
The 2026–27 State Budget papers list stamp duty relief for buyers aged 60 or over who sell their home and move to a property with a smaller land area. It covers contracts from 25 March 2026 for a newly built home, an off-the-plan apartment or vacant land to build on.
| Replacement property | Full relief up to | Partial relief | Largest saving |
|---|---|---|---|
| New home or off-the-plan apartment | $2,000,000 | Phases out to $2,100,000 | $103,830 |
| Vacant land | $1,200,000 | Phases out to $1,300,000 | $59,830 |
Partial relief shrinks evenly across the $100,000 band. For example, a $2,050,000 new home attracts $106,580 of duty, half of which ($53,290) is relieved. Applications for the refund can be made within 5 years of settlement.
