Stamp duty (RevenueSA calls it conveyance duty) is a state tax on buying property. In South Australia it is calculated on the greater of the price you pay or the market value, and your conveyancer normally pays it for you at settlement.
The rate table
| Value of the property | Stamp duty |
|---|---|
| Up 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 |
Part of $100 counts as a full $100.
Worked examples
- $450,000 home: $11,330 + ($150,000 ÷ 100 × $5.00) = $18,830
- $600,000 home: $21,330 + ($100,000 ÷ 100 × $5.50) = $26,830
- $800,000 home: $21,330 + ($300,000 ÷ 100 × $5.50) = $37,830

First home buyers
For contracts signed on or after 6 June 2024, eligible first home buyers pay no stamp duty, whatever the price, when buying:
- a new home
- an off-the-plan apartment
- vacant land to build a new home on
Established (previously lived-in) homes are not covered. The main conditions:
- Every applicant is 18 or over, and at least one is an Australian citizen or permanent resident
- You live in the home as your main residence for at least six continuous months
- For contracts from 13 February 2025, neither you nor your spouse or partner has previously held an interest in residential property in Australia
- The foreign ownership surcharge is not covered by the relief
The First Home Owner Grant is a separate scheme with similar rules. Ask your conveyancer to check both before you sign.
Other relief
RevenueSA also offers relief for seniors aged 60 and over who downsize to a newly built home, off-the-plan apartment or land (contracts from 25 March 2026), and ex gratia relief for victim-survivors of family, domestic or sexual violence (contracts from 4 June 2026). Eligibility is detailed on the RevenueSA site.
Other costs at settlement
Stamp duty is only one part. Budget for Land Services SA registration fees, your conveyancer’s fee and searches. See conveyancing fees by state, then compare conveyancers in Adelaide or across South Australia.
