Stamp duty is a fee imposed for official documents by state governments. It is typically paid when buying cars and other assets like land or shares. This one-time payment is made when you transfer ownership of a new or used vehicle from a dealer or private seller.

The cost of stamp duty is determined by the state where the car is registered and the vehicle’s price. Other factors that affect stamp duty price are vehicle type and engine.

Check out the tables below to see how much you’ll have to pay in your state.

New South Wales

How much does stamp duty on a car cost in Australia’s most populous state? In NSW, it’s calculated using either the car’s market value or the purchase price value, whichever is higher.

The car stamp duty calculation in NSW is fairly simple, as shown in the table below:

Vehicle Value Duty Payable
Up to $44,999 $3 for every $100
Passenger vehicles worth $45,000 or more $1,350, plus $5 for every $100

South Australia

In addition to vehicle price, stamp duty in South Australia is calculated based on whether the vehicle is a commercial or non-commercial vehicle. Stamp duty on non-commercial vehicles is calculated as follows: 

Value Amount of Stamp Duty
Does not exceed $1,000 $1 for every $100 or part of $100, with a minimum of $5 payable in all cases
Exceeds $1,000 but not $2,000 $10 plus $2 for every $100 or part of $100 over $1,000
Exceeds $2,000 but not $3,000 $30 plus $3 for every $100 or part of $100 over $2,000
Exceeds $3,000 $60 plus $4 for every $100 or part of $100 over $3,000

The same tariffs apply to business vehicles up to $2,000. If the vehicle's worth exceeds $2,000, the stamp duty charge is $30 plus $3 per $100 or fraction of $100 over $2000. 

Tasmania

Tasmania's stamp duty rates are calculated depending on the vehicle's dutiable value. The rates for passenger vehicles, which are classified as constructed to carry up to 9 adult persons (including off-road vehicles but do not include motorcycles, utilities, and panel vans), are as follows:

Dutiable Value Duty Payable
$0 to $600 $20
$600 to $35,000 $3 per $100, or part thereof, of dutiable value
$35,000 to $40,000 $1,050 plus $11 per $100, or part thereof, that the dutiable value exceeds $35,000
Over $40,000 $4 per $100, or part thereof, of dutiable value

Heavy vehicles classified as those over 4.5 tonnes GVM (except campervans) have a duty payable of $1 per $100, or part thereof, of dutiable value, with a minimum of $20.

For electric and hydrogen fuel-cell vehicles, duty is exempt on the registration of both new and second-hand ones registered between 1 July 2021 and 30 June 2023. Duty is also exempt for new electric and hydrogen fuel-cell vehicles with a contract of sale entered before 25 May 2023.

Victoria

The car stamp duty rate in Victoria is calculated based on the car's market value or the purchase price (whichever is greater) and is divided by the type of vehicle.

Western Australia

Stamp duty in WA is calculated based on the vehicle's 'dutiable value,' which is either the manufacturer's list price (for new vehicles) or a realistic market value (for used cars).

The car stamp duty rates in WA for non-heavy vehicles are:

Dutiable Value Value Rate
Up to $25,000 2.75% of dutiable value

Over $50,000 6.5% of dutiable value

For heavy vehicles (weighing over 4.5 tonnes), you will have to pay 3% of the dutiable value with a maximum cap of $12,000.

Australian Capital Territory

Stamp duty in the ACT is calculated using a combination of a car's price and the Federal government's Green Vehicle Guide rating. The rating takes into account the carbon dioxide emissions in grams per kilometre and classifies vehicles accordingly.

As of 1 July 2024, new car categories have been released. Vehicles are classified into these categories: AAA, AA, A, B, C, and D. The "greenest" models are classified as Class AAA, while the "worst" ones are classified as Class D. Class C cars are those with average environmental performance.

Vehicle Performance Rating Duty amounts payable for vehicles valued below $ 45,000.00 Duty amounts payable for vehicles valued at $45,000 or more
New category AAA, AA, A, used eligible hybrid, used eligible PHEV $ nil $ nil
New category B, new motorcycle (other than a category AAA vehicle) $1 for every $100, or part of $100, of the dutiable value. $450, plus $2 for every $100, or part of $100, of the dutiable value.
Non-rated vehicles (other than a used ZEV/Category AAA) $3 for each $100, or part of $100, of the dutiable value. $1,350 plus $5 for every $100, or part of $100, of the dutiable value.
