Stamp duty affects your real deposit

Transfer duty cannot normally be added to the home loan. It needs to be paid at settlement, so it affects how much cash you need above your deposit, legal fees, inspections and moving costs.

First home buyer concessions can be valuable, but the thresholds depend on transaction date, property type and location. For a full breakdown of how the thresholds work and how they interact with the FHOG, First Home Guarantee and other benefits, see our WA stamp duty guide for first home buyers.

Frequently asked questions

How much is stamp duty in WA for first home buyers?

Under the current law (in force since 21 March 2025), eligible WA first home buyers pay no transfer duty on a home at or under $500,000, with a concessional rate up to $700,000 in Metropolitan or Peel and $750,000 in regional WA. For vacant land the duty-free threshold is $350,000, concessional to $450,000. On 7 May 2026 the WA Government announced higher thresholds ($600,000 duty free for homes, concessional to $800,000) with an estimated commencement of 28 July 2026, pending legislation. The calculator on this page covers both rate sets so you can compare them for your contract date.

Can I add stamp duty to my home loan in WA?

Not normally. Transfer duty has to be paid at settlement from your own funds, on top of your deposit, legal fees and other costs. This is the piece that catches buyers who have saved exactly enough for the deposit alone: the duty bill decides how much cash you really need on settlement day. First home buyer concessions can reduce the bill to zero depending on the price, which is exactly what this calculator shows you.

Is stamp duty the same as transfer duty in WA?

Yes. Transfer duty is the official name RevenueWA uses for the tax paid when property changes hands in Western Australia; stamp duty is the everyday name most people search for. This calculator estimates WA transfer duty, including the first home buyer concessional rates.

When do the 2026 first home buyer stamp duty changes start in WA?

The increased thresholds were announced by the WA Government on 7 May 2026 as part of the 2026-27 State Budget, applying to eligible transactions entered into on or after that date. RevenueWA has advised the changes cannot be implemented until legislation passes and its systems are updated, with an estimated commencement of 28 July 2026. Eligible transactions signed before commencement are assessed under the previous rates first, then reassessed and refunded. Confirm the current position with RevenueWA or your settlement agent before signing.
