What is the WA first home buyer stamp duty exemption threshold?+
Western Australia offers a full stamp duty exemption for first home buyers on properties valued up to $430,000. A partial concession applies for values between $430,001 and $530,000. For vacant land, the full exemption applies up to $300,000 with a partial concession to $400,000.
Does WA have a foreign buyer surcharge?+
Yes — foreign buyers in WA pay an additional 7% surcharge on residential property purchases. This applies on top of the standard transfer duty rates. Australian citizens and permanent residents are not subject to this surcharge.
How is WA stamp duty different from other states?+
WA stamp duty rates are among the more competitive in Australia, particularly for mid-range property values. The first home buyer thresholds ($430,000 full exemption) are lower than NSW or VIC, reflecting the different average property prices in the WA market.
Is stamp duty payable on off-the-plan properties in WA?+
Yes — stamp duty is payable on off-the-plan properties in WA, calculated on the contract price. Unlike some other states, WA does not offer a specific off-the-plan stamp duty concession. However, if the property qualifies under first home buyer thresholds, those concessions still apply.
When must stamp duty be paid in WA?+
Stamp duty (officially called 'transfer duty') in WA must be paid within 2 months of the date of contract or agreement. Your settlement agent or conveyancer handles payment to the WA Office of State Revenue as part of the settlement process.
