How Stamp Duty Works in Western Australia

Stamp duty in Western Australia, officially known as transfer duty, is a state government tax administered by the WA Department of Finance (Revenue WA). It applies to every property purchase in the state, including houses, apartments, townhouses, vacant land, and commercial properties. WA transfer duty represents a significant upfront cost and should be factored into your purchase budget alongside your deposit and other settlement expenses.

WA transfer duty is calculated on the dutiable value of the property, which is the greater of the purchase price or the unencumbered value (market value). The duty uses a marginal rate system with five brackets, starting at 1.9% for the first $120,000 and rising to 5.15% for the portion above $725,000. This progressive system means the effective rate increases as the property price rises.

Current WA Transfer Duty Rates

The 2026 WA transfer duty rates consist of five brackets. For a typical Perth property purchased at $650,000, the transfer duty would be approximately $24,878. WA's rates sit in the middle of the pack nationally, generally lower than NSW and Victoria but higher than Queensland. The rates are published by Revenue WA and apply uniformly across all regions of Western Australia.

Unlike NSW and Victoria, WA does not have a separate premium rate bracket for very high-value properties. The top rate of 5.15% applies to all amounts above $725,000 without any further escalation. This makes WA relatively competitive for properties in the $1 million and above range.

First Home Buyer Exemptions and Concessions

Western Australia offers first home buyer transfer duty concessions through the First Home Owner Rate (FHOR) scheme. Eligible first home buyers purchasing a property valued up to $430,000 receive a full exemption from transfer duty. For properties valued between $430,001 and $530,000, a concessional rate applies on a sliding scale, gradually increasing towards the full duty amount.

To qualify for the WA first home buyer exemption, you must be an Australian citizen or permanent resident, be at least 18 years of age, and you (and your spouse or partner) must not have previously owned residential property anywhere in Australia. You must move into the property within 12 months of settlement and live there for a continuous period of at least six months. The concession applies to both new and established homes.

WA also offers a $10,000 First Home Owner Grant for eligible buyers purchasing or building a new home. The grant has a property value cap of $750,000 for established homes and $1,000,000 for new homes. This grant can be claimed in addition to the stamp duty exemption, providing significant combined savings for first home buyers.

Foreign Buyer Surcharge

Foreign buyers purchasing residential property in WA are subject to an additional 7% surcharge on top of the standard transfer duty. This surcharge applies to foreign individuals (those who are not Australian citizens or permanent residents), foreign corporations, and trustees of foreign trusts. The 7% rate is calculated on the full dutiable value of the property.

For example, a foreign buyer purchasing a $750,000 property in Perth would pay approximately $29,740 in standard transfer duty plus $52,500 in foreign buyer surcharge, totalling around $82,240. WA's foreign surcharge of 7% is slightly lower than the 8% charged in NSW, Victoria, and Queensland.

Off-the-Plan and House-and-Land Packages

WA does not offer a formal off-the-plan stamp duty concession. However, house-and-land packages structured with separate land and building contracts attract duty only on the land component. This is a common strategy in Perth and regional WA where new housing estates frequently offer house-and-land packages. Duty is calculated on the land contract only, while the building contract is not subject to transfer duty.

For a house-and-land package totalling $550,000 with a $250,000 land component, transfer duty would be calculated on $250,000 only, saving potentially $10,000 or more compared to purchasing an equivalent established property at $550,000.

Vacant Land Rates

Standard transfer duty rates apply to vacant land purchases in Western Australia. First home buyers purchasing vacant land up to $300,000 to build their home on may be eligible for a full transfer duty exemption under the first home owner rate for vacant land. For vacant land valued between $300,001 and $400,000, a concessional sliding scale rate applies. These vacant land thresholds are separate from the residential property thresholds.

Buying vacant land and building remains one of the most effective strategies to minimise total stamp duty in WA, as duty is only calculated on the land price and not on the cost of construction. Combined with the First Home Owner Grant for new builds, first home buyers can achieve substantial savings.

Investment vs Owner-Occupier

In Western Australia, the standard transfer duty rates are the same for owner-occupiers and investors. The key difference is that investors cannot access first home buyer exemptions or concessions. Owner-occupiers who qualify as first home buyers can save the full duty amount on properties up to $430,000, representing potential savings of over $14,000.

For investment properties, stamp duty is not immediately tax-deductible. It is added to the cost base of the property for capital gains tax (CGT) purposes, reducing your taxable capital gain when you sell. Investors should account for stamp duty as part of their overall investment analysis alongside rental yields, capital growth, and ongoing costs such as land tax.

How and When to Pay

In WA, transfer duty must be paid within two months of the dutiable transaction. For most property purchases, this means two months from the date of the contract of sale. Your settlement agent (the WA equivalent of a conveyancer) will arrange for the duty to be assessed and paid as part of the settlement process.

Payment is made through Revenue WA's online portal or via your settlement agent. Late payment attracts penalty tax and interest. Some lenders may allow you to capitalise stamp duty into your home loan, though this increases your total borrowing, your LVR, and may require Lenders Mortgage Insurance (LMI).
