How Australian Capital Territory car stamp duty works
When you buy a car in Australian Capital Territory, stamp duty is charged on the dutiable value, which is the price you paid or the market value, whichever is higher, including GST. Rate depends on the vehicle’s emissions rating, its value, and whether it is new or used. Look up the CO2 rating on the Australian Government Green Vehicle Guide; a new schedule applies from 1 February 2027. The duty is paid to ACT Revenue Office when the vehicle is registered or transferred into your name, so it sits on top of the purchase price and the usual registration costs.
