How stamp duty in SA is calculated (2026 edition)
South Australia’s stamp duty (officially “stamp duty on land and buildings” and “motor vehicle duty”) is calculated on the dutiable value. For property, that’s generally the purchase price or market value. For vehicles, it’s the purchase price or market value whichever is higher. Below are the current progressive brackets effective 2026.
