Australia · Stamp Duty
South Australia has the steepest top rate in the country at 7% above $1 million, though its median price sits far below that, so most Adelaide buyers land in the 4–5.5% bands. The state abolished stamp duty for first home buyers on homes up to $650,000 from June 2025 as part of a staged reform. Off-the-plan buyers also receive duty reductions as construction progresses.
Preset rates are indicative reference values only. Confirm current rates and any reliefs with your local tax authority.

The buyer pays the tax in essentially every case in this market. It is payable in full before or at settlement and cannot normally be added to a mortgage, so it must be part of your cash budget alongside the deposit.
How we calculate: the calculator applies the official band schedule marginally — each rate applies only to the slice of the price inside its band, exactly as the revenue authority does. Worked examples are computed with the same function.
