Australian stamp duty calculator
Estimate the transfer (stamp) duty on a property purchase in any state or territory — and see how much an eligible first-home buyer could save in Victoria and New South Wales.
Estimate only — general information, not advice. Figures use each state's standard transfer-duty scale for FY 2025–26 and exclude the foreign-purchaser surcharge, off-the-plan, vacant-land, pensioner and other concessions. First-home concessions are modelled for VIC and NSW only and are simplified. Rates and thresholds change — always confirm the exact amount with the relevant state revenue office before you budget. Rates last reviewed June 2026. Propact does not provide financial, legal or tax advice.
How stamp duty is calculated
Every state and territory sets its own transfer-duty scale. Duty is charged on the property's dutiable value — generally the purchase price or market value, whichever is higher — on a progressive basis, so a higher price attracts a higher marginal rate. The calculator above applies each jurisdiction's published scale to the price you enter.
On top of the base duty, some buyers pay extra (for example a foreign-purchaser surcharge) and many pay less through concessions. Those aren't included in the base estimate — they depend on your circumstances and the property type.
First-home buyers
Most states reduce or remove stamp duty for eligible first-home buyers, but the rules differ widely. Victoria gives a full exemption up to $600,000 and a concession to $750,000; New South Wales a full exemption up to $800,000 and a concession to $1,000,000. Queensland, WA, SA, Tasmania, the ACT and NT each run their own schemes — some income-tested, some limited to new builds.
This tool models the VIC and NSW concessions (simplified). For other states it shows standard duty and links you to the revenue office so you can check what you're entitled to.
Stamp duty — common questions
What is stamp duty?
Stamp duty — officially transfer duty or land transfer duty — is a tax each Australian state and territory charges when property changes hands. It's calculated on the property's dutiable value (usually the price or market value, whichever is higher) using a progressive scale, so the rate rises with the price.
How much is stamp duty in Australia?
It depends on the state and the price. As a rough guide, on a $750,000 home an owner-occupier might pay around $20,000–$40,000 depending on the state. Use the calculator above for an estimate in your state, then confirm the exact figure with that state’s revenue office.
Do first-home buyers pay stamp duty?
Often less, or none. Most states offer a first-home-buyer exemption or concession. For example, eligible Victorian first-home buyers pay no duty up to $600,000 (with a concession to $750,000), and in New South Wales eligible buyers pay none up to $800,000 (with a concession to $1,000,000). Other states use income tests or new-build rules — check your state revenue office.
Is this stamp duty calculator accurate?
It's an estimate using each state's standard transfer-duty scale for FY 2025–26. It does not include the foreign-purchaser surcharge, off-the-plan, vacant-land, pensioner or other concessions, and first-home concessions are modelled for VIC and NSW only. Always confirm the exact amount with the relevant state revenue office before you budget.
