How does transfer duty work in Western Australia?

Transfer duty in Western Australia is a one-off tax payable when you purchase property. It is calculated on the purchase price (or market value, whichever is higher) using progressive rate brackets. Higher-value properties attract a higher marginal rate, up to a top rate of 5.15%.

First home buyers: No duty up to $430,000; concession up to $530,000.

Foreign buyers: 7% foreign transfer duty on residential property.

Worked example: Western Australia transfer duty

Purchase price: $550,000

Estimated transfer duty: $20,140

For a property valued at $550,000 in WA: first $120,000 = $2,280, $120,001-$150,000 = $855, $150,001-$360,000 = $7,980, $360,001-$550,000 = $9,025. Total = $20,140 (approximately 3.66% effective rate).

Use the calculator above to estimate transfer duty for any purchase price. The calculator also shows how Western Australia compares with other Australian states.

City scenario: Perth

Perth purchases near bracket boundaries can shift total duty quickly, so re-checking numbers before exchange is often worthwhile.

In a Perth scenario around $550,000, this page estimates upfront duty around $20,140 under current published rates.

Verify your result with the official source

Cross-check your estimate against official guidance from Department of Finance WA . Confirming rates and concessions there helps validate assumptions before settlement.

Western Australia purchase-planning context

WA duty outcomes are often sensitive around the first-home owner rate thresholds. Investors should model standard transfer duty directly, rather than assuming owner-occupier concessions transfer across.

At higher price points, WA moves to a 5.15% top marginal band. In growth corridors where values move quickly, reassessing duty assumptions before exchange can prevent late budget blowouts.

Is stamp duty tax deductible?

Stamp duty paid on the purchase of an investment property is not an immediately deductible expense. Instead, it forms part of the cost base of the property for capital gains tax (CGT) purposes. This means when you eventually sell the investment property, the stamp duty you paid at purchase reduces your taxable capital gain, lowering your CGT liability.

For your principal place of residence, stamp duty is generally not tax deductible at all, as the main residence CGT exemption means the cost base is typically irrelevant.
