General rates only: concessions, exemptions, first-home schemes and foreign surcharges are not modelled, and GST treatment of new property is out of scope.

Enter the property value to estimate the general transfer duty.

Summary

Choose a jurisdiction and enter a dutiable value to see the band that applies and how it is built.

Working

  1. The dutiable value selects one published band (or, in the Northern Territory, the statutory formula or a percent-of-value slab).
  2. Per-$100 bands: duty = base amount + rate per $100 × the number of whole or part hundreds above the threshold.
  3. Percentage bands: duty = base amount + percent × the value above the threshold, or percent × the whole value for a slab row.
  4. Statutory formula: D = a × V² + b × V with V = value ÷ 1,000, floored to the nearest 5 cents.
  5. Any statutory minimum duty is applied last.

Assumptions

  • General (non-concessional) rates only, at the rule pack's effective date.
  • The dutiable value is the figure you enter; revenue offices may assess a different value.
  • Valuation date 2026-10-01 selects the effective rule pack for every jurisdiction shown.

Limitations

  • Concessions, exemptions, first-home and off-the-plan schemes, pensioner rates and foreign-purchaser surcharges are not modelled.
  • Mortgage registration, transfer registration and other lodgement fees are separate from duty and are not included.
  • GST treatment of new residential property, and the margin scheme, are out of scope.
  • Where a jurisdiction's rates have not been transcribed and verified, the row shows no figure rather than an estimate.
