WA Stamp Duty
Stamp duty in Western Australia, formally known as transfer duty, is a state government tax levied on the transfer of property. Calculated as a percentage of the property's dutiable value, the cost varies significantly depending on the purchase price, property type, and buyer eligibility for concessions. Because it is an upfront cost separate from standard purchase deposits and moving expenses, accurate calculation is essential for budgeting.
The purchaser or acquirer of the property is liable to pay the stamp duty on the transaction.
You have 2 months after the date that liability for duty on the dutiable transaction arises to lodge the transaction with the WA Office of State Revenue:

Stamp Duty Rates WA & other fees
For standard property purchases in Western Australia, stamp duty operates on a marginal scale. As the dutiable value increases, the applicable rate applies only to the portion of the value within that specific bracket.
For transactions entered into on or after 1 July 2023, the general rates apply as follows:
| Purchase Price/Value | Stamp Duty Rate |
|---|---|
| $0 to $120,000 | $1.90 per $100 or part thereof |
| $120,001 to $150,000 | $2,850 plus $2.85 per $100 over $120,000 |
| $150,001 to $360,000 | $3,705 plus $3.80 per $100 over $150,000 |
| $360,001 to $725,000 | $11,700 plus $4.75 per $100 over $360,000 |
| Over $725,000 | $29,037.50 plus $5.15 per $100 over $725,000 |
The dutiable value is generally the greater of the purchase price or the market value of the property at the date of the transaction.

2026 Legislative Updates: First Home Owner Rate of Duty (FHOR)
The Western Australian State Government has introduced significant budget measures affecting first home buyers, announced on 7 May 2026. These changes substantially increase the thresholds for duty exemptions and concessions on established homes and vacant land.
New and Established Homes
- Full Exemption: No duty is payable for newly built or established homes valued up to $600,000 (previously $500,000).
- Concessional Rate: A concessional rate applies to newly built or established homes valued between $600,000 and $800,000 (previously capped at $700,000).
Vacant Land
- Full Exemption: No duty is payable for vacant land valued up to $450,000 (previously $350,000).
- Concessional Rate: A concessional rate applies to vacant land valued between $450,000 and $550,000 (previously capped at $450,000).
2026 Legislative Updates: First Home Owner Grant (FHOG) Decoupling
Historically, eligibility for the First Home Owner Grant value caps was linked to the First Home Owner Rate of Duty. The 7 May 2026 announcements remove this link, enabling eligible first home buyers to access a duty concession even if the value of the transaction exceeds the FHOG cap.
Additional FHOG changes include increasing the grant cap for homes south of the 26th parallel of South Latitude to $800,000. This accounts for rising construction costs and ensures eligible purchasers building a house are not disadvantaged.
2026 Legislative Updates: Off-the-Plan Duty Concession
On 12 March 2026, the State Government announced an extension of the off-the-plan duty concession. Key changes include:
- Extension: The concession is now valid for transactions entered into until 30 June 2028.
- Increased Thresholds: Value thresholds have been raised to accommodate current market conditions.
- Expanded Eligibility: Eligible transactions now include new dwellings purchased off-the-plan in survey-strata and community titles (land) schemes.
This concession reduces the percentage of duty payable for pre-construction and under-construction contracts entered into on or after 12 March 2026.
2026 Legislative Updates: Foreign Transfer Duty Exemption
A new foreign transfer duty exemption has been established for 'build-to-sell' developments. To qualify, the development must result in a net addition of at least one dwelling to the housing supply. This measure aims to stimulate housing construction and increase supply within the state.
Commencement Dates and Reassessment Protocols
The changes announced in May and March 2026 cannot be implemented immediately. They require the introduction of relevant legislation into Parliament and subsequent system updates by the Office of State Revenue. The commencement date for these updates is currently estimated to be 28 July 2026.
For administration purposes, transactions entered into between the relevant announcement date and the 28 July 2026 commencement date will be initially assessed using the rates, thresholds, and caps that applied prior to the announcements. Once the legislation and systems are live, these eligible transactions can be reassessed, and a refund will be issued to the purchaser for any overpaid duty.
Calculating Duty on Complex Transactions
Beyond standard purchases, transfer duty in WA applies to several other transaction types, each with specific valuation and concession rules:
- Vacant Land: Duty is assessed on the land value, and first home buyer concessions may apply if construction is intended.
- Commercial Property: Standard rates apply without access to residential concessions or grants.
- Gifted Property: Even if no money changes hands, transfer duty is assessed on the market value of the property.
- Tenancy in Common: When a share of a property is transferred, duty applies only to the transferred portion's dutiable value.
Foreign Buyer Surcharge
Foreign purchasers acquiring residential property in Western Australia are subject to an additional foreign buyer surcharge (7%). This is calculated on top of the standard transfer duty rates. However, with the new 'build-to-sell' exemption effective from the 7 May 2026 announcement date, qualifying foreign investors contributing to net housing supply may be exempt from this surcharge.
