How Stamp Duty Works in WA

Understanding Transfer Duty in Western Australia

In Western Australia, stamp duty is officially called transfer duty. It is calculated on a sliding scale based on the dutiable value of the property — typically the higher of the purchase price or market value.

In addition to transfer duty, buyers also pay a mortgage registration fee if taking out a home loan. Both are typically paid at or before settlement through your settlement agent.

First home buyers in WA may be eligible for a full or partial exemption from transfer duty on properties up to $600,000, with a concession applying between $600,001 and $750,000. The First Home Owner Grant of $10,000 may also apply to new builds.

 
Rates are set by the WA State Government and are subject to change. Always confirm with a licensed settlement agent or conveyancer before proceeding.

The True Cost of Buying in Perth

Stamp Duty Is Only Part of the Picture

When budgeting for a Perth property purchase, stamp duty is often the largest upfront cost — but it is not the only one. Plan for all of these before you make an offer.

Transfer Duty (Stamp Duty)

The largest upfront government cost. Calculated on the dutiable value on a sliding scale from 1.9% to 5.15%. Use the calculator above for your exact figure.

Mortgage Registration Fee

A government fee to register your mortgage with Landgate. The amount scales with your loan size — typically a few hundred dollars and included in the calculator above.

Settlement Agent Fees

A licensed settlement agent or conveyancer handles the legal transfer of ownership. Fees typically range from $1,500 to $2,500 for a standard Perth residential property.

Building & Pest Inspection

Strongly recommended before purchasing any established Perth home. A combined building and timber pest inspection typically costs $400–$700 and can reveal issues that affect price or your decision to proceed.

Lender Fees

Some lenders charge application, valuation, or loan establishment fees. These vary by lender and product — your mortgage broker can help identify and minimise these costs before you apply.

Council & Water Rate Adjustments

At settlement, council rates and water rates are adjusted proportionally between buyer and seller. Your settlement agent handles this automatically — but factor it into your budget when planning your purchase.

As a general rule, budget an additional 4–6% of the purchase price on top of your deposit to cover all upfront buying costs in Perth.

Stamp Duty in Perth — What Every WA Buyer Needs to Know

Stamp duty in Western Australia — officially transfer duty — is one of the most significant costs when buying a Perth property. On a $750,000 home, general transfer duty is approximately $28,453. For a first home buyer purchasing at the same price, a partial concession may significantly reduce this figure. Use the calculator above to get an accurate estimate based on your specific situation.

Are you a first home buyer in WA? The State Government offers a full transfer duty exemption for eligible first home buyers purchasing properties valued up to $600,000, and a partial concession on properties between $600,001 and $750,000. The First Home Owner Grant of $10,000 is also available for eligible applicants building or purchasing a new home. The calculator above includes these concessions automatically when you select "First Home Buyer."

Selling before you buy? While stamp duty is a fixed government charge, your real estate selling costs are not. Most Perth sellers pay their agent 2.4% in commission. Choosing a 1% commission agent instead saves you up to $10,500 on an $800,000 sale — which could cover a significant portion of your stamp duty on the next property.
