The 2026-27 first home owner boost

Announced in the 7 May 2026 State Budget, the first home owner rate of duty now gives:

PurchaseOld thresholdNew (2026-27)
Home — full exemption$500,000$600,000
Home — concession up to$700,000$800,000
Vacant land — full exemption$350,000$450,000
Vacant land — concession up to$450,000$550,000
Timing note: contracts signed before the legislation passes on 28 July 2026 are initially assessed at the old rates and then reassessed with a refund once it passes. Don't delay a purchase just for the thresholds — the benefit is back-dated.

With Perth's median house price sitting near the new exemption cap, a large share of WA first home buyers will now pay no duty at all — a saving of roughly $20,000 at $600,000.

Everyone else

Owner-occupiers who've owned before and investors pay the standard scale — there's no general owner-occupier concession like Queensland's. Foreign buyers add a 7% surcharge. Duty is due within a month of the assessment notice, normally settled through your conveyancer.

Worked example

A $620,000 established house: standard duty is $11,115 + 4.75% × $260,000 = $23,465. An eligible first home owner in 2026-27 pays only the concessional amount for the $600k–$800k band — a small fraction of that — where under last year's rules the same buyer would have received nothing at all.

Frequently asked questions

How much can a first home buyer spend in WA without paying stamp duty?
Up to $600,000 for a home and $450,000 for vacant land under the 2026-27 Budget thresholds, with concessional rates running to $800,000 and $550,000 respectively.
I signed a contract in June 2026 — do I get the new thresholds?
Yes. Contracts signed between the 7 May 2026 announcement and the legislation passing on 28 July 2026 are reassessed and refunded the difference once the law passes.
How much is stamp duty on a $500,000 house in WA?
Standard duty is about $17,765. An eligible first home owner pays $0 — $500,000 is comfortably under the $600,000 exemption threshold.
Is there an owner-occupier concession in WA if I've owned before?
No. Unlike Queensland, WA's concessional duty rate is only for first home owners (linked to First Home Owner Grant eligibility). Everyone else pays the standard scale.
