How WA calculates vehicle stamp duty

Western Australia charges Vehicle Licence Duty at 2.75% of value up to $25,000, a sliding rate between $25,000 and $50,000, and 6.5% on vehicles over $50,000 — applied to the full value, not just the excess. Heavy vehicles over 4.5 tonnes pay 3%, capped at $12,000.

At $100,000, you're in the luxury range — top duty tiers apply, and cars over $80,000 may also attract the separate federal Luxury Car Tax (which is not stamp duty).

WA Vehicle Licence Duty rate tiers

Value band Rate
Up to $25,000 2.75%
$25,000 – $50,000 2.75% – 6.5% (sliding)
Over $50,000 6.5% of full value
Heavy (over 4.5t) 3% (capped at $12,000)

WA applies 6.5% to the FULL value once a car passes $50,000, so crossing the $50,000 mark causes a sharp jump in duty.

When do I pay vehicle stamp duty in WA?
In Western Australia, vehicle stamp duty (Vehicle Licence Duty) is typically paid when you register or transfer a vehicle into your name. For new vehicles from a dealer, it's usually included in the on-road costs. For private sales, you pay when transferring registration.
Why does a $55,000 car attract much more duty in WA?
Above $50,000, WA charges 6.5% on the entire value rather than just the amount over $50,000. A $55,000 car is taxed at 6.5% of $55,000, so duty rises steeply once you cross $50,000.
Is there a stamp duty cap in WA?
Only for heavy vehicles over 4.5 tonnes, which pay 3% capped at $12,000. Standard light passenger vehicles have no cap — the 6.5% rate applies to the full value above $50,000.
Is vehicle stamp duty the same as property stamp duty?
No. Vehicle stamp duty and property stamp duty are completely separate taxes with different rates. Vehicle duty is generally much lower — typically 3-5% of the vehicle's value compared to up to 5-7% for property.
