Enter the amount and the rate currently in force in Australia; the stamp duty calculator is then computed in Australian Dollar. Because rates change, always confirm the figure that applies to your case in Australia. Enter the stamp duty rate for Australia as a plain percentage (15 means 15%, not 0.15).

• 1

  Australia publishes stamp duty figures in Australian Dollar, revised periodically — enter the rate currently in force for your case in Australia rather than an older stored figure so the result matches the official calculation.

• 2

  A stamp duty result for Australia is only as current as the rate you typed in: when the figure matters, re-run it with a freshly confirmed Australian Dollar rate instead of one saved last month.

• 3

  Treat the computed Australian Dollar amount as the base figure for Australia: any additional local fees, deductions, or rounding rules that apply to your situation must be added separately, so the number you rely on stays honest and complete.

• This page computes in Australian Dollar, Australia's currency: pasting a figure from a neighboring country's calculator mixes currencies silently. Re-run the number on the matching country page so the Australian Dollar basis holds.

• Assessed value is not market value: Australia property levies apply the official assessment or band to the rate, so typing the Australian Dollar purchase price alone can misstate the bill. Use the assessment on the official notice as the base.
