South Australia stamp duty calculator
Estimate South Australia transfer (stamp) duty at 2026–27 rates. The calculator is set to South Australia; change any input to see your figure.
First-home buyers of a new home pay no duty, with no cap on its value. Established homes don't qualify, and this calculator doesn't model the new-home exemption yet, so it shows full duty for every first-home purchase in South Australia. Foreign purchasers of residential property in South Australia pay a surcharge of 7% on top of standard duty.

What is stamp duty?
Stamp duty, officially transfer duty, is a one-off tax charged by each Australian state and territory when you buy property or land. The buyer pays it, and it's calculated on the higher of the purchase price or the property's market value.
It's usually one of the largest upfront costs of a purchase after the deposit. How much you pay depends on the property's value, which state it's in, and whether you qualify for a concession or owe a surcharge.
How stamp duty is calculated
Duty is worked out on a sliding scale of brackets: the portion of the price in each band is charged at that band's rate, so the effective rate rises with the property value. Every state and territory publishes its own brackets, which is why an identical purchase price produces very different duty across the country. On top of the base duty, foreign purchasers pay a surcharge in most states, and first-home buyers and some owner-occupiers may receive concessions that reduce or remove it. The calculator above uses the 2026–27 rates for each state and starts on the standard investor scale; change the buyer type to see a first-home concession where the calculator models one.
Stamp duty by state and territory (2026–27)
| State or territory | Foreign buyer surcharge | First-home buyer duty relief |
|---|---|---|
| New South Wales | 9% | Full exemption ≤ $800k, phasing out to $1.0m |
| Victoria | 8% | Full exemption ≤ $600k, phasing out to $750k |
| Queensland | 8% | Effectively nil duty ≤ $700k, phasing out to $800k |
| South Australia | 7% | New homes only: full exemption, no value cap |
| Western Australia | 7% | Nil duty ≤ $600k, concessional to $800k |
| Tasmania | 8% | No first-home duty concession (exemption ended 30 Jun 2026) |
| Northern Territory | None | No duty concession (grants only) |
| Australian Capital Territory | None | Full exemption, no price or income cap |
Surcharges apply on top of standard duty for foreign purchasers of residential property. First-home relief is subject to eligibility conditions and generally excludes investment purchases. Figures are the general (investor) transfer-duty scale, and owner-occupiers may pay less in some states.
