Worked example
Take a resident purchasing a $700,000 home in South Australia. The SA progressive schedule applies each rate to only the slice of the price in that band. The first $12,000 at 1 percent gives $120; the next $18,000 (up to $30,000) at 2 percent gives $360; the next $20,000 (up to $50,000) at 3 percent gives $600; the next $50,000 (up to $100,000) at 3.5 percent gives $1,750; the next $400,000 (up to $500,000) at 4 percent gives $16,000; and the remaining $200,000 above $500,000 at 5.5 percent gives $11,000. The total is about $29,830, an effective rate near 4.26 percent. South Australia is higher than Queensland but close to the national average for a property at this price point.
How it is calculated
South Australia conveyance duty is calculated on the higher of the purchase price or the market value of the property. The calculator applies the SA progressive schedule band by band: 1 percent on $0 to $12,000; 2 percent on $12,001 to $30,000; 3 percent on $30,001 to $50,000; 3.5 percent on $50,001 to $100,000; 4 percent on $100,001 to $500,000; and 5.5 percent on amounts above $500,000. For foreign purchasers, an additional 7 percent surcharge is added on the full dutiable value. The result is an estimate only. RevenueSA calculates the exact figure based on the assessed value. Off-the-plan concessions, primary production land, related-party transfers, and pensioner concessions are not modelled here.
Frequently asked questions
How is South Australia stamp duty calculated?
South Australia calls it conveyance duty and calculates it on a progressive schedule. For residential property, rates start at 1 percent on the first $12,000 and rise through six bands to 5.5 percent on amounts above $500,000. Each band applies only to the slice of the price within it, so the effective rate is always lower than the top marginal rate.
Do first home buyers pay stamp duty in South Australia?
South Australia does not provide a stamp duty exemption specifically for first home buyers on existing homes, unlike some other states. First home buyers purchasing a new build may be eligible for the First Home Owner Grant, which is a cash payment rather than a duty concession. Some concessions apply to off-the-plan purchases. Check RevenueSA for the latest eligibility rules, as these change with each state budget.
When is stamp duty paid in South Australia?
Conveyance duty in South Australia is generally due within two months of the liability arising, which is typically the date of the contract. If you are using a conveyancer, they will calculate and pay the duty before settlement. Underpayment or late payment attracts interest at a penalty rate set by RevenueSA.
Is there a foreign buyer surcharge in South Australia?
Yes. South Australia applies a 7 percent foreign ownership surcharge on top of standard conveyance duty for foreign persons purchasing residential land. The surcharge applies to the full dutiable value of the property. Trusts and companies may also be caught if they have foreign beneficiaries or shareholders holding a substantial interest.
