About the Car Stamp Duty Calculator Australia
Every Australian state and territory charges stamp duty when a car is registered or transferred, but each uses a different formula — a flat 3% in the Northern Territory, engine-based rates in Queensland, a whole-value sliding rate in Western Australia. This calculator applies each state’s official rates and shows what the same car would cost in duty everywhere else.

Which state has the cheapest car stamp duty?
It depends on the price. Below about $26,000, Western Australia is cheapest because of its 2.75% rate. From there to $45,000, NSW, Queensland (1–4 cylinders) and the NT all charge 3% (Tasmania too, up to $35,000). Between $45,000 and $100,000 Queensland and the NT stay at 3% while NSW charges 5% on the extra. Above $100,000 the NT’s flat 3% is cheapest. The dearest is Western Australia for mid-priced cars ($3,250 on $50,000) and Victoria for luxury cars ($10,500 on $150,000).
You cannot simply register in a cheaper state: duty is owed where the car is garaged and registered, which must match where you live.
What every state has in common
Duty is charged on the dutiable value — the GST-inclusive price for a new car, and the higher of the price paid and the market value for a used car. Trade-ins do not reduce it. Dealers include duty in the drive-away price; in a private sale the buyer pays it when transferring the registration.
Stamp duty is separate from registration, compulsory third party (CTP) insurance, number plates and transfer fees. A dealer’s drive-away price usually includes all of them; a private sale does not, so budget for duty on top of the price.
ACT
The ACT is not included yet because its duty depends on the car’s emissions performance rating as well as its price. Use the ACT Revenue Office calculator for cars registered in Canberra.

In every state covered here, the same rates apply to new and used passenger cars. Used cars are charged on the higher of the price and the market value.
Is stamp duty included in the drive-away price?
Yes, a dealer drive-away price normally includes stamp duty, registration and CTP. A private sale price does not.
