What is the Western Australia stamp duty calculator?

The Stamp Duty Calculator WA estimates the transfer duty that may apply to a property purchase in Western Australia. Enter the dutiable value and the calculator applies the matching RevenueWA general rate band, including its base amount and the marginal charge above the band threshold.

The calculator is useful when comparing purchase prices or estimating how much money may be needed at settlement. It shows transfer duty only and does not replace an official assessment or include the other professional, registration and lending costs connected with a property purchase.

How WA transfer duty is calculated

Western Australia’s general transfer duty schedule is progressive. The first band charges $1.90 per $100 of value. Each later band begins with a fixed base amount and then adds a marginal charge for every $100, or part of $100, above its lower threshold.

  1. Enter the property purchase price or another relevant dutiable value.
  2. The calculator selects the matching WA general duty band.
  3. It combines the band’s base duty with its marginal charge.
  4. The result shows estimated transfer duty and its effective rate against the entered value.

WA transfer duty rates

Dutiable valueGeneral transfer duty
$0–$120,000$1.90 per $100
$120,001–$150,000$2,280 + $2.85 per $100 over $120,000
$150,001–$360,000$3,135 + $3.80 per $100 over $150,000
$360,001–$725,000$11,115 + $4.75 per $100 over $360,000
More than $725,000$28,453 + $5.15 per $100 over $725,000

Worked example: $500,000 property

A $500,000 dutiable value falls in the $360,001–$725,000 band. Start with $11,115, then add $4.75 for each of the 1,400 lots of $100 above $360,000. The estimated general WA transfer duty is $17,765, an effective rate of about 3.55%.

First home buyer transfer duty in WA

For contracts dated on or after 7 May 2026, an eligible first home buyer may pay no transfer duty when the dutiable value is $600,000 or less. A partial concession may apply from $600,001 to $800,000.

The supplied thresholds apply across Western Australia, with the previous metropolitan and regional difference removed. The calculator does not automatically apply this relief because eligibility and the exact concession require transaction details beyond the property value. The general-rate estimate can be used as a cautious starting point until RevenueWA or a conveyancer confirms the concession.

What the estimate includes

The result includes only transfer duty under the listed WA general rate bands. It does not assess first home buyer status or include title registration, settlement agent or legal fees, property inspections, lender charges, mortgage insurance, moving costs or settlement adjustments.

Disclaimer: this Western Australia stamp duty estimate is general information only and is not financial, legal or tax advice. Confirm the current rates, dutiable value, concession eligibility and final amount with RevenueWA or a qualified settlement agent before relying on the result.

Frequently asked questions

How much is stamp duty on a $500,000 property in WA?

Using the general RevenueWA schedule supplied for this calculator, estimated transfer duty is $17,765 before any first home owner concession.

Do first home buyers pay transfer duty in Western Australia?

For contracts from 7 May 2026, an eligible first home buyer may pay no duty up to $600,000 and may receive a partial concession between $600,001 and $800,000.

Are the first home buyer thresholds different in regional WA?

Not under the supplied rules from 7 May 2026. The same $600,000 full-exemption and $800,000 concession ceiling applies across WA.

Does the calculator apply the first home owner concession?

No. It shows the general transfer duty amount because eligibility and the exact concession cannot be established from the purchase price alone.

What value should I enter?

Enter the dutiable value used for the transfer. The purchase price can be suitable for a planning estimate, but an official assessment may use another value in some transactions.

Does the estimate include settlement fees?

No. The result covers general transfer duty only. Settlement agent, registration, finance, inspection and other purchase costs need to be considered separately.
