In South Australia an eligible first home buyer’s duty turns on whether the home is new, not its price: $0 on a new home, full duty on an established one. Decide which you’re buying before you set your budget.

SA stamp duty worked examples: $500,000, $750,000 and $1,000,000
What stamp duty comes to at three common prices, worked by the calculator above on the RevenueSA rates. A foreign buyer pays the 7% foreign ownership surcharge on top.
| Price | Standard rate | First home buyer | Foreign surcharge |
|---|---|---|---|
| $500,000 | $21,330 | $21,330 | $35,000 |
| $750,000 | $35,080 | $35,080 | $52,500 |
| $1,000,000 | $48,830 | $48,830 | $70,000 |
The figures exclude the land titles registration and transfer fees. First home buyer figures assume an established home and that you meet the eligibility rules set out below.
SA stamp duty rates 2026
RevenueSA charges stamp duty on a marginal scale: each slice of the price is taxed at its own rate and the slices stack, so the effective rate rises slowly as the price rises rather than jumping. Rates are per $100 or part of $100, so the value is rounded up to the next $100 first.
A $750,000 home falls in the top band, over $500,000, so the duty is $21,330 plus $5.50 for every $100 over $500,000. That is $21,330 + $13,750 = $35,080, an effective rate of 4.68%.
| Dutiable value | Duty |
|---|---|
| Up to $12,000 | $1.00 per $100 |
| $12,001 to $30,000 | $120 plus $2.00 per $100 over $12,000 |
| $30,001 to $50,000 | $480 plus $3.00 per $100 over $30,000 |
| $50,001 to $100,000 | $1,080 plus $3.50 per $100 over $50,000 |
| $100,001 to $200,000 | $2,830 plus $4.00 per $100 over $100,000 |
| $200,001 to $250,000 | $6,830 plus $4.25 per $100 over $200,000 |
| $250,001 to $300,000 | $8,955 plus $4.75 per $100 over $250,000 |
| $300,001 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 |

First home buyer thresholds in SA
South Australia gives no stamp duty relief on an established home, so a first home buyer pays the full rate on an existing house or unit: $35,080 on $750,000.
Buying new is different. An eligible first home buyer pays no stamp duty on a new home, an off-the-plan apartment or vacant land to build a first home, with no cap on the value for contracts entered into on or after 6 June 2024 (RevenueSA). Before that date, full relief applied to a new home only up to $650,000, phasing out to $700,000.
Our SA first home buyer guide covers the First Home Owner Grant and the eligibility rules in full.
SA stamp duty concession rates
SA has one schedule for every buyer. The only home-buyer relief is for first home buyers, and it turns on the kind of property, not the price.
| Purchase | Duty for an eligible first home buyer |
|---|---|
| Established home | Full duty ($35,080 on $750,000) |
| New home | $0, no value cap |
| Off-the-plan apartment | $0, no value cap |
| Vacant land to build a first home | $0, no value cap |
Foreign buyer surcharge in SA
A foreign person or foreign trust buying residential land in South Australia pays a foreign ownership surcharge of 7% of the value on top of stamp duty, for instruments from 1 January 2018 (RevenueSA). On a $750,000 home that adds $52,500.
Exemptions: who pays less or nothing in SA
- First home buyers of a new home. No duty on a new home, off-the-plan apartment or vacant land for a first home, no value cap.
- Established homes. No relief for anyone: $35,080 on a $750,000 home.
Each one has its own eligibility test, set out by RevenueSA. A concession you are not entitled to can be reassessed with interest and penalties, so confirm it before settlement.
What is stamp duty in SA?
Stamp duty in South Australia is the state tax charged on the conveyance, or transfer, of land. It is the biggest upfront government cost you face after the deposit itself.
The buyer pays it, not the seller, and it falls due around settlement. It is charged on the purchase price and rises on a scale, so a dearer home carries a higher bill and a higher effective rate. RevenueSA collects it, and your conveyancer handles the lodgement and payment.
When do you pay stamp duty in SA?
The buyer pays stamp duty, not the seller, and it is normally paid at settlement. Your conveyancer or solicitor works out the figure, lodges the transaction with RevenueSA and pays the duty from the settlement funds, so you rarely deal with the revenue office yourself.
Budget for it as cash on top of your deposit from the start: on a $750,000 home in SA it is $35,080 for an owner-occupier. Late payment can attract interest, which is one more reason the timing sits with your conveyancer. Our conveyancing guide explains who does what at settlement.

Common questions
How much is stamp duty on a $800,000 house in SA?
On RevenueSA's rates, stamp duty on an $800,000 established home is $37,830: $21,330 plus $5.50 per $100 over $500,000, an effective 4.73%. Owner-occupiers, investors and first home buyers pay the same. An eligible first home buyer of a new home pays $0. A foreign buyer adds the 7% surcharge, $56,000.
Do first home buyers pay stamp duty in SA?
On an established home, yes, at the full rate: $21,330 on a $500,000 home. On a new home, an off-the-plan apartment or vacant land to build a first home, an eligible first home buyer pays nothing, with no value cap for contracts from 6 June 2024 (RevenueSA). So whether the home is new decides the bill, not the price.
How do I avoid paying stamp duty in SA?
For a first home buyer, buy new: RevenueSA gives full relief on a new home, off-the-plan apartment or vacant land with no value cap (contracts from 6 June 2024), which saves $35,080 at $750,000. There is no relief on an established home, and no lower owner-occupier rate, so everyone else pays the schedule on this page.
When do you pay stamp duty in SA?
Normally at settlement. Your conveyancer or solicitor calculates the stamp duty, lodges it with RevenueSA and pays it out of the settlement funds, so the money has to be ready on the day on top of your deposit. On a $750,000 home in SA that is $35,080 for an owner-occupier. Pay late and interest can be charged, which is why the conveyancer handles the timing.
Is SA stamp duty the same for an investment property?
Yes. South Australia charges one set of rates whoever the buyer is, so an investor pays the same as an owner-occupier: $35,080 on a $750,000 home and $48,830 on $1,000,000 (RevenueSA). A foreign investor also pays the 7% foreign ownership surcharge.
