Keep this SA number for tax time
Stamp duty adds to your CGT cost base, so it lowers the tax you pay when you eventually sell. Vestly stores it against the property and tracks cashflow, depreciation, and deductions across your whole portfolio.

How SA stamp duty works
South Australia charges stamp duty on property transfers under the Stamp Duties Act 1923. RevenueSA publishes the schedule. The 9-band scale below applies to general (non-FHB) purchases.
South Australia transfer duty brackets (FY 2025-26)

|---|---|
| $0 - $12,000 | $1.00 per $100 |

| $30,001 - $50,000 | $480 + $3.00 per $100 over $30,000 |
| $50,001 - $100,000 | $1,080 + $3.50 per $100 over $50,000 |
| $100,001 - $200,000 | $2,830 + $4.00 per $100 over $100,000 |

Worked example
A South Australian investor buying a $600,000 residential property in Adelaide pays approximately $26,830 in SA stamp duty (before any first-home buyer concession or foreign-acquirer surcharge).
First-home buyer concessions
From 6 June 2024, first-home buyers building or buying a NEW home pay no stamp duty (no price cap from 2024 reforms). The same applies to vacant land intended for an FHB build.
Foreign buyer surcharge
Foreign buyers pay an additional 7% Foreign Ownership Surcharge on residential property.
SA-specific quirks
South Australia has a particularly granular 9-band scale (most states have 4-7 brackets). The top marginal rate of 5.5% kicks in at $500,001.
Common questions
When is South Australian stamp duty payable?
Within 2 months of the contract date. Most transactions settle through PEXA, which handles duty payment automatically.
How is SA stamp duty calculated for a $600,000 investor purchase?
Sitting in the $500,001+ bracket: $21,330 + 5.5% of ($600,000 - $500,000) = $21,330 + $5,500 = $26,830.
Is the SA first-home buyer scheme really stamp-duty-free?
Yes - for NEW homes and vacant land purchased to build, there is no upper price cap (post-June 2024 reforms). Existing homes do not qualify.
Does SA have an off-the-plan concession?
No - SA abolished its off-the-plan apartment concession in 2018.
What about the SA foreign-owner surcharge?
A 7% Foreign Ownership Surcharge on residential property, on top of the general rate. Stacks for any foreign person buyer.
Is there an SA pensioner concession?
No specific stamp duty pensioner concession. Other state cost-of-living relief may apply.

Stamp duty is only one line item. The national Upfront Costs Calculator adds your deposit, LMI estimate, legal fees, inspections, and lender fees - the complete cash-at-settlement figure.
