WA Stamp Duty Calculator
Estimate transfer duty for a Western Australian property purchase using current RevenueWA rates, including the first home buyer thresholds that commenced for contracts from 7 May 2026.
The 7 May 2026 first home buyer thresholds have commenced and apply to eligible transactions entered into on or after that date, statewide. If you settled between 7 May 2026 and commencement and paid duty at the previous thresholds, RevenueWA states the assessment can be reviewed and a refund issued, so it is worth raising with your settlement agent.

This is an estimate, not a quote or an assessment.

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?
Eligible WA first home buyers pay no transfer duty on a home at or under $600,000, with a concessional rate applying up to $800,000. Above $600,000 the rate is $16.15 for every $100 of value above that threshold. For vacant land the duty-free threshold is $450,000, concessional to $550,000, at $20.14 per $100 above $450,000. These thresholds apply to transactions entered into on or after 7 May 2026 and are statewide, so the old split between Metropolitan or Peel and regional WA no longer applies to the first home owner rate. Source: RevenueWA, Duties Fact Sheet: First Home Owner Rate, last updated 30 July 2026, checked 14 August 2026. Contracts entered into between 21 March 2025 and 6 May 2026 are assessed under the previous thresholds ($500,000 duty free for homes), and the calculator covers both sets so you can pick 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?
They have commenced. The increased thresholds were announced on 7 May 2026 in the 2026-27 State Budget and apply to eligible transactions entered into on or after that date. RevenueWA originally estimated commencement of 28 July 2026 while legislation and system updates were completed, and that work is now done: RevenueWA states that eligible transactions in that window which have not settled can be self-assessed at the new rates in Online Duties, and those already settled at the old rates can be reassessed with a refund issued. Source: RevenueWA, 2026-27 Housing Taxation Package, page last updated 29 July 2026, checked 14 August 2026. If you settled a first home purchase between 7 May and late July 2026 and paid duty at the old thresholds, it is worth asking your settlement agent about a reassessment.
