Stamp Duty Calculator Australia

How transfer duty works

Transfer duty — commonly called stamp duty — is a state tax on the transfer of property. Every state and territory sets its own thresholds and rates, so the same price attracts different duty in different places.

The brackets work like income tax brackets: a fixed amount for the bracket the price falls in, plus a marginal rate applied to the part of the price above that bracket’s threshold. The calculation steps above show which bracket applied and how the amount was built.

Transfer and mortgage registration fees are separate from duty. They are published schedule fees and are shown as their own line so they are not mistaken for part of the duty figure.

What this calculator assumes

A standard investment purchase. No first home buyer, owner-occupier, pensioner or off-the-plan concession is applied, because eligibility depends on facts a public page cannot establish — and telling you that you qualify when you do not is worse than telling you nothing.

Duty is calculated on the price you enter. Where a state assesses duty on the higher of price or market value, a valuation can change the figure.

The foreign purchaser option applies the surcharge the shared rate tables hold for that state. Surcharges change, sometimes mid-year, which is why the rate version and review status are printed with the result rather than left implicit.

Confirm before you commit

Duty is assessed by the state revenue office, not by this calculator. Treat the figure here as an amount to check, not an amount to budget from, and have your conveyancer confirm it against your contract.

The rate tables here are shared with the Virtual Buyers Agent app rather than kept as a separate copy, so a re-verification updates both at once. The version, the applicable financial year and the next scheduled review date are shown with every result so you can see how current they are.
