WA Property Duty Calculator

Estimate Western Australian property transfer duty using locally stored, date-aware rate rules.

Estimate Western Australian property transfer duty—commonly called stamp duty—without leaving your current browser tab. The WA Property Duty Calculator provides: • a general transfer-duty estimate using published WA rate brackets; • supported concessional and first-home-owner rate assumptions; • an optional estimated 7% foreign buyers duty; • clear date, property-type and location assumptions; • warnings where an announced rule is pending or individual eligibility must be checked; and • direct access to RevenueWA’s official calculator and Legal Care Australia’s detailed guidance. Calculations happen locally in the extension. It does not request browser permissions, collect personal information, transmit calculation inputs or save calculation history. This extension provides general information only. It is not an official RevenueWA calculator, assessment, legal advice or financial advice. Rates, thresholds, concessions and eligibility can change. Check the official RevenueWA calculator before relying on an estimate. This calculator is for property transfer duty. It does not calculate vehicle licence duty.
