Stamp Duty Calculator — WA
This is a focused Western Australian transfer duty (stamp duty) calculator for residential purchases. It applies the RevenueWA rate schedule to the dutiable value and the residential or concessional rate where the property will be the buyer’s principal place of residence. Confirm with RevenueWA or your settlement agent before relying on the figure.
What this calculator does
Western Australia applies separate general and residential rate schedules, plus a distinct first home owner rate schedule with some of the most generous thresholds in the country. This calculator applies the appropriate schedule based on occupancy and first home buyer status, and flags the foreign buyer surcharge where applicable.
Legal basis
WA transfer duty is imposed under the Duties Act 2008 (WA), Chapter 2. Rates and concessions are administered by RevenueWA. The first home owner rate schedule sits under s 147 of the Act.
How the calculation works
Apply the RevenueWA rate schedule under the Duties Act 2008 (WA) — residential rate where the property is the buyer’s PPR, general rate otherwise. If a first home buyer, apply the first home owner rate under s 147 (exemption up to the lower threshold, tapered concession to the upper threshold, with separate thresholds for established homes and vacant land). If a foreign person, add the 7% foreign buyer surcharge.

For a $600,000 established PPR purchase by a non-first-home-buyer, estimated WA transfer duty at the residential rate is around $22,000–$23,000.
In the meantime, use the worked example above to validate your figures and confirm the final amount with the relevant revenue office or authority before relying on it in a matter.

Calculator FAQs
Are the RevenueWA rates current?
The calculator uses the RevenueWA rate schedule as at the build date shown in the result. Rates are indexed — confirm against wa.gov.au/revenuewa before relying on the estimate.
What is the residential rate?
WA applies a reduced residential rate to property acquired as the buyer’s principal place of residence. The calculator applies it when the PPR flag is set.
What is the first home owner rate?
Under s 147 of the Duties Act 2008 (WA), eligible first home buyers pay no duty up to the lower threshold and a tapered rate up to the upper threshold. Thresholds differ for established homes and vacant land and are indexed.
Does WA have a foreign buyer surcharge?
Yes — a 7% foreign buyer duty surcharge applies to residential acquisitions by foreign persons under the Act. The calculator adds it when the foreign purchaser flag is set.
Is this legal or financial advice?
No — it is an estimator. Confirm with RevenueWA or your settlement agent before relying on it.
Does it cover off-the-plan apartments?
The standalone off-the-plan duty rebate for apartments is a separate, finite scheme with its own eligibility — it is not modelled in this calculator. Check the current scheme status with RevenueWA.
What about commercial property?
WA continues to tax commercial transfers under transfer duty (unlike Victoria’s CIPT transition). The calculator is residential only — use RevenueWA directly for commercial transfers.
