Stamp Duty in South Australia
South Australia has a detailed progressive bracket system with rates ranging from 1% to 5.5%. SA sits at the higher end of stamp duty costs nationally, particularly for mid-range properties. The system has 9 separate brackets, creating a finely graded progression.
First Home Buyer Concessions — SA
South Australia's first home buyer relief is unusual — there is no stamp duty exemption or concession for established homes. However, first home buyers purchasing a new home, an off-the-plan apartment or vacant land to build on pay no stamp duty, with no property value cap. The SA First Home Owner Grant is up to $15,000 for new homes, and has had no price cap for contracts from 6 June 2024.
Additional Information
SA charges a 7% foreign buyer surcharge on residential purchases. South Australia is also notable for having duty-free transfers for qualifying commercial land, which can benefit property developers.
