Stamp Duty Calculator WA FY2026-27
Every rate here checked against its official source on or after 2026-08-19 — per-source dates listed below.
This calculator works out WA transfer (stamp) duty on a property purchase — duty payable, the effective rate, and the first home owner rate of duty (FHOR) if you qualify — using Revenue WA's own FY2026-27 rate tables.
Independent and free to use — no lender referral, no email capture, no quote wall. This page just calculates the duty and shows its working.
New thresholds, now law: the 2026-27 WA Budget's first-home increases have commenced — no duty on homes to $600,000 (concession to $800,000; vacant land $450,000/$550,000), statewide, for transactions entered into on or after 7 May 2026. Signed on or after 7 May but assessed at the old rates before commencement? You can be reassessed for a refund — details in the FAQs below.

Stamp duty by property value, general rate vs first home owner rate (FY2026-27)
Duty payable for a range of property values, computed from the engine above. Cells marked † are above the $800,000 FHOR ceiling for homes — the general rate applies with no saving.
| Property value | General rate | First home owner rate (home) |
|---|---|---|
| $500,000 | $17,765 | $0 |
| $550,000 | $20,140 | $0 |
| $600,000 | $22,515 | $0 |
| $650,000 | $24,890 | $8,075 |
| $700,000 | $27,265 | $16,150 |
| $750,000 | $29,741 | $24,225 |

| $850,000 | $34,891 | $34,891 † |
How this is calculated
WA transfer duty is a bracketed schedule: each bracket has a published base amount of duty at its floor, plus a marginal rate applied "per $100 or part thereof" of the excess — the excess is rounded UP to the next whole $100 before the rate applies. One subtlety this engine reproduces exactly: Revenue WA's published base for the top bracket ($28,453 at $725,000) embeds its own round-up — the chain value computes to $28,452.50, which is what RevenueWA's own calculator returns at exactly $725,000, while values above $725,000 build on the published $28,453. Both behaviours are golden-tested against RevenueWA's calculator.
| Dutiable value | Base duty at floor | Marginal rate on excess |
|---|---|---|
| $0 – $120,000 | $0 | 1.9% per $100 |
| $120,000 – $150,000 | $2,280 | 2.9% per $100 |
| $150,000 – $360,000 | $3,135 | 3.8% per $100 |
| $360,000 – $725,000 | $11,115 | 4.8% per $100 |
| $725,000 and over | $28,453 | 5.2% per $100 |
The first home owner rate is not a discount off the general schedule — it's its own schedule: nil duty up to the exemption threshold ($600,000 for homes, $450,000 for vacant land), then a flat concessional rate per $100-or-part on just the excess ($16.15 for homes, $20.14 for vacant land, statewide). It cuts out entirely — a hard cliff back to the general rate on the whole value — above the ceiling ($800,000 homes, $550,000 vacant land). These are the rates for transactions entered into on or after 7 May 2026, taken verbatim from Revenue WA's First Home Owner Rate fact sheet (updated 30 July 2026), whose own worked example (a $400,000 home → no duty under the FHOR) the engine reproduces.
"Total government costs" adds Landgate's lodgement fees to duty: the transfer registration fee scales with value ($225.10 up to $85,000, stepping to $255.10 at $200,000, then $20 per $100,000-or-part above that — captured directly from Landgate's own fee calculator, the same way the LMI page captures Helia's rate table), plus a flat $225.10 to register a mortgage. Foreign buyers duty, when toggled, is 7% of the dutiable value, its own line on top of duty.

What this doesn't model
- Contracts entered into before 7 May 2026. Rates apply to the date the agreement was signed, and this page models the current (post-Budget) FHOR schedule — earlier contracts fall under the previous thresholds (see the FAQ above for those figures, and Revenue WA's fact sheet for the full history).
- The concessional rate (s 147) for certain business-property and principal-residence transactions valued up to $200,000, and nominal-duty categories — niche schedules this page doesn't offer.
- The off-the-plan duty concession (up to a 100% rebate for pre-construction contracts, extended and expanded for contracts from 12 March 2026) — if you're buying off-the-plan, your duty can be substantially lower than the figures here.
- FHOG eligibility itself. The first-home toggle assumes you qualify for the first home owner rate; it doesn't test citizenship/residency, age, prior property ownership or the occupancy requirement.
- Foreign buyers duty edges: part-foreign co-purchase apportionment (this page applies 7% to the whole value), exemptions, and landholder acquisitions.
If any of these apply to you, the duty you actually owe will differ from the figures above.
Frequently asked questions
How much is stamp duty in WA?
Western Australia assesses transfer duty on one general scale — owner-occupiers and investors pay the same, and the brackets aren't indexed. Worked from RevenueWA's published table, duty is $17,765 on a $500,000 purchase, $24,890 at $650,000, $27,265 at $700,000 and $34,891 at $850,000 — effective rates of 3.6% to 4.1% of the price. An eligible first home buyer pays the first home owner rate instead: no duty at all up to $600,000, then $16.15 per $100 of the excess up to the $800,000 ceiling. The concession shrinks as the price rises and has all but run out by the ceiling: a first home at exactly $800,000 attracts $32,300 against $32,321 at the general rate a dollar above it — a difference of $21, versus $16,815 saved at $650,000. Landgate lodgement fees are payable on top of duty.
How much is stamp duty on $650,000 in WA?
At the general rate, WA transfer duty on a $650,000 property is $24,890 for FY2026-27 — an effective 3.8% of the value. An eligible first home buyer anywhere in WA pays the first home owner rate instead: $8,075, a saving of $16,815. On top of duty, Landgate charges $355.10 to register the transfer and $225.10 to register a mortgage.
What are the WA first home buyer stamp duty thresholds?
For transactions entered into on or after 7 May 2026, an eligible first home buyer pays no duty on a new or established home valued up to $600,000. Between $600,001 and $800,000, duty is $16.15 per $100 (or part of $100) of the excess over $600,000 — one statewide schedule; the old metro/regional split is gone. Above the $800,000 ceiling the concession disappears entirely and the whole value is assessed at the general rate. Vacant land: no duty to $450,000, then $20.14 per $100 of the excess up to a $550,000 ceiling. Source: Revenue WA's First Home Owner Rate fact sheet (updated 30 July 2026).
Did the WA first home buyer thresholds change in 2026?
Yes — the 2026-27 WA State Budget increases (announced 7 May 2026) are now law. Eligible first home buyers pay no duty on homes up to $600,000 with a concessional rate to $800,000, and no duty on vacant land to $450,000 with a concession to $550,000, for transactions entered into on or after 7 May 2026. If you signed on or after 7 May 2026 and your duty was assessed under the old rates before the change commenced, you can apply to RevenueWA for a reassessment and refund of the difference (via the Online Services Portal). This calculator applies the new schedule.
I signed my contract before 7 May 2026 — what rates apply to me?
Rates apply to the date the agreement was entered into, not the settlement date. For contracts signed between 21 March 2025 and 6 May 2026, the previous first home owner rate applies: no duty on a home up to $500,000, then $13.63 per $100 of the excess in the Perth metropolitan/Peel regions (to a $700,000 ceiling) or $11.89 per $100 elsewhere in WA (to $750,000); vacant land was nil to $350,000, then $15.39 per $100 to $450,000. This page calculates the current schedule — for an earlier contract, check the historical rows on Revenue WA's First Home Owner Rate fact sheet.
Do foreign buyers pay extra stamp duty in WA?
Yes. Foreign persons or entities acquiring residential property in WA pay foreign buyers duty — an additional 7% of the dutiable value on top of transfer duty. On a $650,000 home that's an extra $45,500. The toggle on this page applies the surcharge to the whole value (a 100% foreign interest); where only part of the property is acquired by a foreign person, the surcharge applies only to that share.
What government fees apply on top of stamp duty in WA?
Landgate lodgement fees, which scale with the property value: $355.10 to register the transfer at $650,000 (from $225.10 for lower-value properties, rising $20 per $100,000 of value above $200,000), plus a flat $225.10 to register a mortgage if you're buying with a loan. These are regulated fees, not subject to GST, and this page adds them to duty in the "Total government costs" line. PEXA/electronic-settlement platform charges are a private cost on top.
