On a $30,000 light vehicle in WA: 3.5% of the price.
How it’s worked out
3.5% of $30,000 (the rate slides with the price), rounded down to the nearest 5 cents
Duty only. The yearly registration is a separate bill, which the rego calculator works out, and exemptions vary. Confirm with WA Treasury before relying on it.
How WA charges vehicle duty
WA is the only state whose rate is a formula, not a table: 2.75% under $25,000, then a rate that slides up continuously — R = 2.75 + (value − 25,000) ÷ 6,666.66 — until it pins at 6.5% from $50,000. The calculator above rounds the rate to two decimals, as WA Treasury publishes it, and floors the duty to 5 cents.
Between $25,000 and $50,000 the rate itself moves with the price — every extra $6,666.66 of car adds a full percentage point. A $30,000 car pays about 3.5%, a $40,000 car about 5%, a $50,000 car the full 6.5%. There are no brackets to game; the slide is continuous.
Two rounding quirks matter for matching RevenueWA to the cent: the sliding rate is rounded to two decimals before it is applied, and the resulting duty is floored to the nearest 5 cents. We probed the official calculator to confirm both (a $35,050 car comes out at exactly $1,493.10).
Above $50,000 the rate holds at 6.5% of the whole value — $6,500 per $100,000 of vehicle. Against every other state’s everyday car, WA is the dearest of the eight from about $35,000 to $100,000; above $100,000, Victoria’s luxury bands (7%, then 9% of the whole value) cost more. Unlike the eastern states there is no engine, emissions or luxury distinction: one schedule for every light vehicle. For a new vehicle, dealer delivery is excluded from dutiable value.
WA vehicle licence duty (light vehicles)
| Value / vehicle | Duty |
|---|---|
| Up to $25,000 | 2.75% of dutiable value |
| $25,000 – $50,000 | R% of the whole value, R = 2.75 + (value − 25,000) ÷ 6,666.66 |
| Over $50,000 | 6.5% of dutiable value |
The sliding R is rounded to 2 decimals, and the duty is then rounded DOWN to the nearest 5 cents — both matched by probes of RevenueWA’s own calculator.
Worked examples
- $20,000 used hatch: $550 of duty. Flat zone — 2.75%.
- $40,000 mid-size SUV: $2,000 of duty. Mid-slide — the rate itself is now about 5%.
- $80,000 LandCruiser: $5,200 of duty. Top rate: 6.5% of the whole price.

Exemptions in Western Australia
Caravans and camper trailers are exempt, as are transfers between spouses or de facto partners of private-use vehicles up to 3 tonnes, and transfers under family-court orders. A deceased-estate transfer pays a nominal $20. For a new vehicle, dealer delivery is excluded from dutiable value — one small mercy at the 6.5% end.
