Asking about WA luxury car tax? Here’s the twist: there isn’t a separate WA luxury car tax—Australia’s Luxury Car Tax (LCT) is federal, applies nationwide, and is charged at 33% on the GST-inclusive portion of a car’s price above the annual threshold.
So in WA you’ll cop LCT (if you’re over the threshold), plus GST, plus WA’s vehicle licence duty, which scales up with price and bites hardest on high-value passenger cars, then rego, CTP and the usual dealer bits.
No, it’s not double-dipping; it’s more of a layered pavlova of taxes where the sweet bit is buried under a lot of cream.
Practical tip: fuel-efficient vehicles have a higher LCT threshold, and WA’s duty rates vary by vehicle type and price—use the ATO and WA Revenue calculators before you sign anything.
