How WA stamp duty is calculated (2026-27)
Rates checked 15 Oct 2026 against RevenueWA.
Western Australian transfer duty is charged on the dutiable value (the higher of the price and the market value) for every $100 or part of $100. This calculator uses the RevenueWA rates for 2026-27.
| Dutiable value | Duty (general rate) |
|---|---|
| $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 |
| Over $725,000 | $28,453 + $5.15 per $100 over $725,000 |
Concessional home rate: for a home you'll live in valued at $200,000 or less: $1.50 per $100 up to $120,000, then $1,800 + $4.04 per $100 over $120,000. A $150,000 home costs $3,012 instead of $3,135. Above $200,000 the general rate applies.
First home buyers (the first home owner rate): no duty on a home valued at $600,000 or less, from 7 May 2026. From $600,001 to $800,000 duty is $16.15 per $100 over $600,000: $8,075 on a $650,000 home. Above $800,000 the general rate applies. At least one buyer must be an Australian citizen or permanent resident.
Foreign purchasers pay an extra 7% of the dutiable value on top of duty. If you buy with an Australian citizen or permanent resident, it applies only to the foreign buyer's share.
Worked example: a $700,000 home: $11,115 + $4.75 × 3,400 (the $100s over $360,000) = $27,265. An eligible first home buyer pays $16.15 × 1,000 = $16,150, and a foreign buyer pays $27,265 + $49,000 surcharge = $76,265.
