SA stamp duty rates
South Australia's scale is steeply progressive and, unlike NSW, not indexed:
| Property value | Duty payable |
|---|---|
| $0 – $12,000 | 1% |
| $12,001 – $30,000 | $120 + 2% over $12,000 |
| $30,001 – $50,000 | $480 + 3% over $30,000 |
| $50,001 – $100,000 | $1,080 + 3.5% over $50,000 |
| $100,001 – $200,000 | $2,830 + 4% over $100,000 |
| $200,001 – $250,000 | $6,830 + 4.25% over $200,000 |
| $250,001 – $300,000 | $8,955 + 4.75% over $250,000 |
| $300,001 – $500,000 | $11,330 + 5% over $300,000 |
| Over $500,000 | $21,330 + 5.5% over $500,000 |
New home? First home buyers pay nothing
SA was the first state to completely abolish stamp duty for first home buyers who buy or build new — a new house, unit, townhouse, off-the-plan apartment, house-and-land package, or vacant land to build on. There is no price cap. Combined with the First Home Owner Grant for new builds, the up-front saving on a $600,000 build is around $30,000.
Downsizers join the club in 2026
From 25 March 2026, South Australians aged 60+ who sell their home and buy a newly built home or off-the-plan apartment up to $2,000,000 are also exempt — a deliberate push to free up family homes. Eligibility conditions apply, so check RevenueSA's criteria before contracting.
Investors and everyone else
There's no owner-occupier concession for non-first-home buyers — the standard scale applies whether you live in the property or rent it out. Foreign purchasers add a 7% surcharge. Duty is payable at settlement via your conveyancer.
