Contract signed in 2026-27, residential property, one buyer profile for the whole purchase. How this is calculated
South Australia charges stamp duty on property with a conveyance scale that RevenueSA does not index, so the thresholds do not move from one year to the next: everything above $500,000 is taxed at $5.50 per $100, and a $800,000 established home costs $37,830 whoever buys it. There is no general concession for owner-occupiers. The relief goes to first home buyers of a new home, an off-the-plan apartment or land to build on: for contracts from 13 February 2025 they pay no stamp duty at all, with no value cap. A first home buyer of an established house gets nothing and pays the full scale. Foreign buyers add a 7 % foreign ownership surcharge on their share, which the first home relief does not remove. Separately, the First Home Owner Grant pays up to $15,000 on a new home, with no price cap.
A scale that has not moved
RevenueSA's conveyance table has nine bands, and its thresholds are the same today as in the version we read. We read it from RevenueSA's own page (an archived capture from January 2022, because the site refuses automated readers) and checked it against the seniors relief cap published on 28 April 2026, which matches the duty on $2,000,000 to the dollar.
| Value | Stamp duty |
|---|---|
| $0 to $12,000 | $1.00 per $100 |
| $12,000 to $30,000 | $120 plus $2.00 per $100 over $12,000 |
| $30,000 to $50,000 | $480 plus $3.00 per $100 over $30,000 |
| $50,000 to $100,000 | $1,080 plus $3.50 per $100 over $50,000 |
| $100,000 to $200,000 | $2,830 plus $4.00 per $100 over $100,000 |
| $200,000 to $250,000 | $6,830 plus $4.25 per $100 over $200,000 |
| $250,000 to $300,000 | $8,955 plus $4.75 per $100 over $250,000 |
| $300,000 to $500,000 | $11,330 plus $5.00 per $100 over $300,000 |
| over $500,000 | $21,330 plus $5.50 per $100 over $500,000 |
Because the top band begins at $500,000, most of the prices discussed on this site fall inside it. The marginal rate on the next dollar is 5.5 % from $500,000 upwards, with no higher band for luxury homes.
South Australian duty by buyer and property type
| Price | Established, any buyer | First home, new | First home, established | Foreign buyer |
|---|---|---|---|---|
| $300,000 | $11,330 | $0 | $11,330 | $32,330 |
| $500,000 | $21,330 | $0 | $21,330 | $56,330 |
| $600,000 | $26,830 | $0 | $26,830 | $68,830 |
| $800,000 | $37,830 | $0 | $37,830 | $93,830 |
| $1,000,000 | $48,830 | $0 | $48,830 | $118,830 |
| $2,000,000 | $103,830 | $0 | $103,830 | $243,830 |
The two first home columns tell the whole story. On $600,000 the gap between a new and an established first home is $26,830; on $1,000,000 it is $48,830. That gap is what choosing an existing house costs a first home buyer in South Australia.
First home buyer relief
For contracts signed from 13 February 2025, an eligible first home buyer pays no stamp duty on a new home, an off-the-plan apartment or vacant land on which a home will be built, whatever the price. Established homes are excluded, and the relief never applies to the foreign ownership surcharge. You must occupy the home for a continuous six months, starting within 12 months. See the property types side by side:
Established, new or land: duty for a first home
New home
$0
| Established home | $26,830 |
| Vacant land at this price | $0 |
| Grant on the new home | $15,000 |
The eligibility conditions are set out on the SA first home buyer page.
The First Home Owner Grant
The grant is worth up to $15,000 on a new home, and since 6 June 2024 there is no value cap. It is not paid on vacant land alone. Paired with the duty relief, a first home buyer building new at $700,000 saves $32,330 of duty and receives the grant on top.
Foreign ownership surcharge
A foreign person pays an extra 7 % of the value of the interest they acquire. RevenueSA's worked example uses $600,000: $26,830 of duty plus $42,000 of surcharge.
Seniors downsizing relief from 25 March 2026
Buyers aged 60 and over who sell their principal place of residence and buy a new home, an off-the-plan apartment or land to build on, on a smaller block than before, can claim relief of up to $103,830 for contracts from 25 March 2026. RevenueSA has published the cap; we have not been able to read its detailed conditions, so we do not model this relief in the calculator. The downsizer page compares it with the other states.
South Australia among the eight
For a repeat buyer of an established home, South Australia is one of the dearer places to buy: $37,830 on $800,000, against $32,316 in WA and $30,187 in NSW. For a first home buyer choosing new, it is among the cheapest. The eight-state comparison shows your own case.
