Western Australia stamp duty calculator

WA's general transfer duty rate applies unless a concession applies, on the greater of the price paid and the property's unencumbered value.

The excess over each band threshold rounds up to the next $100 before the rate is applied ("per $100 or part thereof"); the dutiable value itself is rounded down to the nearest whole dollar. (Department of Treasury and Finance (RevenueWA), verified 27 Sep 2026)

Lenders mortgage insurance (LMI) usually applies when you borrow more than 80% of the property’s value. It is not a government charge: premiums vary by lender and insurer, and there is no public schedule of them, so this page gives no figure. See deposit, LVR and LMI. Conveyancing, inspections and loan fees are quote-based: see complete buying costs. To add your deposit, loan repayments and the yearly cost of owning, use the true cost to buy and own calculator.

Duty is charged on whichever is greater: the price paid (including any GST) or the property's unencumbered value. (Department of Treasury and Finance (RevenueWA), verified 27 Sep 2026)

Documents must be lodged within 2 months of the transaction, and duty paid within one month of the assessment notice (practically, at or before settlement). (Department of Treasury and Finance (RevenueWA), verified 27 Sep 2026)

The calculator and every figure on this page come from the same encoded rules, each transcribed from the RevenueWA’s published rates or the legislation and linked to it. They apply by contract date: for a contract outside 1 July 2026 to 30 June 2027 the calculator says the date is not encoded rather than guess. It does not cover companies or trusts, transfers between relatives or spouses, deceased estates, other exemptions and concessions not listed here, or the eligibility conditions each concession carries (residence, prior ownership, income). Confirm your own position with the RevenueWA calculator or a conveyancer before you rely on it.
