How SA stamp duty is calculated (2026-27)
Rates checked 15 Oct 2026 against RevenueSA.
South Australian stamp duty on a property transfer is charged on the dutiable value (the higher of the price and the market value) for every $100 or part of $100, and RevenueSA quotes it to the cent. The same scale applies whether you'll live in the home or rent it out: South Australia has no owner-occupier discount.
| Dutiable value | Stamp duty |
|---|---|
| $0 – $12,000 | $1.00 per $100 |
| $12,001 – $30,000 | $120 + $2.00 per $100 over $12,000 |
| $30,001 – $50,000 | $480 + $3.00 per $100 over $30,000 |
| $50,001 – $100,000 | $1,080 + $3.50 per $100 over $50,000 |
| $100,001 – $200,000 | $2,830 + $4.00 per $100 over $100,000 |
| $200,001 – $250,000 | $6,830 + $4.25 per $100 over $200,000 |
| $250,001 – $300,000 | $8,955 + $4.75 per $100 over $250,000 |
| $300,001 – $500,000 | $11,330 + $5.00 per $100 over $300,000 |
| Over $500,000 | $21,330 + $5.50 per $100 over $500,000 |
Worked example: a $600,000 home: $21,330 + $5.50 × 1,000 (the $100s over $500,000) = $26,830. A foreign buyer adds the 7% surcharge, $42,000, for $68,830.
First home buyers pay no stamp duty on a new home, an off-the-plan apartment or vacant land to build a home on, with no price cap for contracts signed on or after 6 June 2024. There's no relief on an established home. At least one buyer must be an Australian citizen or permanent resident, and you must live in the home for at least 6 continuous months, starting within 12 months of settlement (or of the home being ready, for land).
