About You
Pensioner, senior, or concession card holder? You may pay less duty in New South Wales. Check your eligibility with the revenue office.
Estimates only, not financial or legal advice. Duty rates, thresholds, and concessions change and vary by jurisdiction and individual circumstances (including income tests and occupancy requirements). Always confirm with the relevant state revenue office before relying on a figure.
Frequently asked questions
How is stamp duty calculated?
Each state and territory sets its own transfer duty rate table, applied to the dutiable value (usually the purchase price). The calculator uses the published tables for all 8 jurisdictions, including owner-occupier rates where they differ, and the NT formula.
Do first home buyers pay stamp duty?
Often not, below each state’s threshold. For example NSW exempts established homes up to $800,000 with a concession to $1,000,000, VIC exempts up to $600,000 with a concession to $750,000, and QLD exempts established homes up to $700,000 (new homes and vacant land have no cap). The calculator applies your state’s rules and shows exactly what the concession saves.
Is the foreign buyer surcharge included?
Yes. Foreign purchasers pay an additional duty surcharge in most jurisdictions, from 7% to 9% of the property value depending on the state. The ACT and NT do not levy one.
How current are the rates, and can I rely on them?
Rate tables are sourced from each state revenue office and the data date is shown in the footer. Concession tapers are linear approximations and eligibility rules are simplified, so always confirm the final figure with the revenue office before exchanging contracts.
Are location-specific and commercial concessions included?
No. Some narrow concessions tied to a location or property use (for example the regional commercial or industrial concession and the City of Melbourne new residential concession) are not modelled. Standard residential transfer duty is the same statewide, so those special cases would only ever reduce the figure shown, never increase it.
