queensland car stamp duty calculator

In Queensland, “car stamp duty” is called vehicle registration duty, and yes, it’s the little tax that turns a bargain into “hmm”.

The calculator works by taking the dutiable value (usually the purchase price including GST and any LCT) and applying a per-$100 rate based mainly on engine cylinder/rotor count.

Pop in the price and engine details and it’ll spit out the duty—just remember it doesn’t include rego, transfer fee or CTP insurance.

As a ballpark, many buyers see roughly 2–4% of the purchase price, depending on engine size, but use the official QLD calculator for an exact figure.

Hot tip: if you’re cross-shopping used cars, run the numbers on each—sometimes the “cheaper” one isn’t once duty joins the party.
