The stamp duty calculator takes into account the property's dutiable value, the state or territory where it was purchased, and the type of property. To provide the most accurate figures, data is sourced directly from the relevant state or territory office of state revenue.
Calculations, on the other hand, should only be used as a guide. There are a variety of other elements that can influence the cost of stamp duty. Stamp duty laws and taxes are also subject to legislative modification by state and territory governments.
