Stamp Duty on New Cars

Stamp duty is a payment that must be made to the state government at the purchase of any new or used vehicle in Australia. The actual amount of stamp duty and how to calculate it varies quite considerably from state to state but is always calculated based on the GST inclusive cost of the vehicle.

As with home purchases in most Australian states and territories, car stamp duty is generally calculated on a sliding scale, becoming a greater proportion of the vehicle cost as the purchase price increases.

One very important consideration when considering a vehicle purchase is to take into account that when a new vehicle is quoted as ‘on the road’ the stamp duty is generally accounted for. In fact the supplying dealer will pay the stamp duty on your behalf once payment has been received. However, when purchasing a used vehicle from a dealer, bear in mind that the cheque to the dealer will not be the only payment and you will need to calculate stamp duty, car registration length and other transfer charges to get a true idea of the cost. Stamp duty based on the car purchase price and registration charges will have to be paid at the local motor registry following delivery of the vehicle. This is very important to bear in mind when tossing up between a late model used vehicle and a brand new vehicle.

And here’s how the stamp duty calculator actually works:


Stamp duty on cars in Canberra and the ACT is charged as follows

  • 3% of the vehicle price inclusive of GST up to $45,000

New South Wales (NSW)

Stamp duty on vehicle purchases is charged as follows:

  • 3% of the vehicle price inclusive of GST up to $45,000
  • 5% for every dollar over $45,000.

Example – a car costing $65,000, stamp duty would be charged at 3% of $45,000 plus 5% of $20,000 (the amount above the $45,000 threshold) = $1,350 + $1,000 = $2,350
