How much is stamp duty on a $50,000 car in WA?

What value is WA duty charged on?

Duty is charged on the dutiable value of the vehicle, broadly what you pay for it. The rate that applies depends on where that value falls across the low, sliding and high zones, and in every case the rate is worked out on the full value rather than just a portion of it.

Who is exempt from motor vehicle duty in WA?

Western Australia has exemption and concession categories too. Across the states these commonly cover some family transfers, primary producers, and eligible pensioner or veteran concessions. The specifics change, so confirm with the WA revenue office what applies to your transfer before counting on it.

RevenueWA — vehicle licence duty · rates effective 23 February 2026

WA vehicle licence duty is worked out as a rate on the full dutiable value, and unlike the tiered states, that rate is applied to the whole value rather than sliced into bands above a threshold. There are three zones by value: a flat low rate up to a lower threshold, a sliding rate through a middle range where the rate rises as the value rises, and a flat high rate once the value passes the upper threshold.

The sliding middle band is the part to watch. Within it, a dearer car is charged a higher rate on its whole value, so the duty climbs faster than the price does. There's no cylinder or emissions factor here; value is all that counts.

WA vehicle licence duty (non-heavy vehicles)
Dutiable value	Rate
Up to $25,000	2.75% of the full value
$25,000 – $50,000	Sliding: R% = 2.75 + ((value − $25,000) ÷ 6,666.66), of the full value
Over $50,000	6.5% of the full value

The sliding rate R = 2.75 + ((value − 25,000) ÷ 6,666.66), rounded to two decimal places, applied to the FULL value — WA never charges only the excess.
