Build your full landed budget →WA stamp duty, called transfer duty, is the state tax on a property purchase. The Property Plug calculator applies the published WA general rate scale, then layers the first home buyer exemption (no duty on a home to $600,000) and concession to $800,000 in Perth metro. Figures are 2026-27 indicative and should be verified with RevenueWA.
How WA transfer duty is worked out
WA duty is progressive. Each band of the price is charged at its own rate and the bands are summed. The published general rate scale for 2025-26 is below. First home buyers replace this with the concession until their price clears the concession ceiling.
| Dutiable value | Duty (general rate) |
|---|---|
| $0 to $120,000 | $1.90 per $100 |
| $120,001 to $150,000 | $2,280 + $2.85 per $100 over $120,000 |
| $150,001 to $360,000 | $3,135 + $3.80 per $100 over $150,000 |
| $360,001 to $725,000 | $11,115 + $4.75 per $100 over $360,000 |
| $725,001 and above | $28,453 + $5.15 per $100 over $725,000 |
Published WA general rate scale, 2025-26. Verify with RevenueWA before relying. A 7% foreign buyer surcharge may apply to non-residents.
What a first home buyer saves
The first home owner rate is the single biggest duty saving in WA. On a $500,000 home a first home buyer pays nothing, where an investor on the general rate would pay roughly $17,765. That saving alone can cover a meaningful slice of a deposit.
- Home up to $500,000: no transfer duty for eligible first home buyers.
- Home $500,001 to $700,000: a concessional rate, phasing up to the general rate (Perth metro and Peel).
- Vacant land up to $450,000: no duty, then a concession to $600,000.
- Above the ceilings: the standard general rate applies with no concession.
Why builders often pay less duty
When you buy a block and sign a separate building contract, transfer duty is generally assessed on the land value, not the finished house-and-land value. So a $560,000 build on a $300,000 block can attract far less duty than a $560,000 established home, where duty is charged on the full price. This is one of the quiet advantages of building new, and we factor it into your budget from the start.

How much is stamp duty in WA for a first home buyer?
For agreements entered into on or after 7 May 2026, an eligible WA first home buyer pays no transfer duty on a home valued up to $600,000, then $16.15 per $100 above $600,000 up to a dutiable value of $800,000. On vacant land there is no duty up to $450,000, then $20.14 per $100 above $450,000 up to $550,000. Above those caps the general rate applies. These thresholds rose from $500,000 and $350,000 under the 2026-27 Housing Taxation Package. Rates apply by the date the agreement is entered into, not the date of settlement. Verify with RevenueWA.
Do investors pay more stamp duty than owner occupiers?
In WA both are assessed on the same general rate of duty above $200,000. The difference is concessions: only eligible owner-occupier first home buyers get the exemption and concessional rate. Investors and subsequent buyers pay the full general rate.
Is stamp duty cheaper when I build rather than buy established?
Often, yes. If you buy the land then build, duty is generally assessed on the land value, not the finished house-and-land value, because the building contract is separate. That can mean materially less duty than buying an equivalent established home. We model this properly for your block on a call.
Did WA stamp duty thresholds change in 2026?
Yes. Under the 2026-27 Housing Taxation Package, the first home owner duty exemption rose from $500,000 to $600,000 on a home, and from $350,000 to $450,000 on vacant land, for agreements entered into on or after 7 May 2026. The concessional ceilings rose to $800,000 and $550,000. If you priced up a build before May 2026, the duty figure you were working from is out of date.
Are these figures guaranteed accurate?
No. This calculator uses the published WA general duty scale and the first home owner rate of duty for agreements from 7 May 2026 as a guide. Rates and thresholds change at state budgets. Always confirm the exact duty with RevenueWA or your settlement agent before you commit.
