Car Stamp Duty Calculator

Vehicle Duty Across Australia

Motor vehicle duty, often called car stamp duty, is charged when a vehicle is registered or transferred to a new owner. The calculator covers New South Wales, Queensland, Victoria, Western Australia, South Australia, Tasmania, the ACT and the Northern Territory. Each state or territory sets its own rates, so the selector changes both the schedule and the questions shown.

Every estimate uses the registration or transfer date, whether the vehicle is new or used, its type and its value. A new vehicle is one that has not been registered before. The calculator covers dates from 1 July 2026 to 30 June 2027. In the ACT, a new table applies to vehicles registered from 1 February 2027.

NSW passenger vehicles and ACT light vehicles pay a fixed amount plus a higher rate on the value above each threshold. For example, a NSW passenger vehicle above $45,000 pays $1,350 plus $5 for each $100 of the excess.

Other schedules apply the higher rate to the whole value. A Queensland light vehicle above $100,000 pays the higher rate on every dollar. Victorian passenger cars move to a higher rate per $200 at each band. Tasmanian passenger vehicles above $40,000 pay $4 per $100 of the whole value. Crossing one of these thresholds by a few dollars can add hundreds or thousands of dollars of duty.

Western Australia's rate rises gradually from 2.75% to 6.5% between $25,000 and $50,000 of value. South Australia has separate schedules for commercial and non-commercial vehicles. The Northern Territory charges $3 per $100 of value for every vehicle type. VicRoads collects Victorian duty at registration or transfer, using rates set by the State Revenue Office.

Queensland asks for the engine type because hybrid and electric vehicles pay a lower rate. The ACT asks for the vehicle's emissions rating, and Tasmania asks whether a new vehicle was bought with a manufacturer's fleet discount. Victoria and the Northern Territory show their concession questions when they apply. For duty on a home or land purchase, use the stamp duty calculator for property.

Value, Vehicle Type and Concessions

Duty is charged on the dutiable value, which is not always the price paid. For a used vehicle, most jurisdictions use the greater of the price and the market value. Market value is what the vehicle would sell for on the open market, including GST. A sale below market value, such as a family discount, still pays duty on the market value.

The Northern Territory uses the price paid for a sale between unrelated parties. A gift or a sale to a related party pays duty on the market value.

New vehicles follow different rules. Queensland and South Australia use the manufacturer's list price with options, even when the dealer discounts the car. Western Australia uses the list price for new cars and motorcycles, and the greater of the price and the market value for a new ute, van or truck. NSW, Tasmania and the Northern Territory use the price paid, including GST. Victoria and the ACT use the greater of the price and the market value.

A trade-in does not reduce the dutiable value. Queensland, Tasmania and the Northern Territory count the trade-in allowance as part of the price paid. In the calculator, a trade-in reduces only the funds still needed.

The calculator supports four vehicle types. Cars, SUVs and people movers use the passenger schedule where one exists. Utes, vans and other goods vehicles with a gross vehicle mass (GVM) of 4.5 tonnes or less are light goods vehicles. Motorcycles and trucks over 4.5 tonnes GVM have their own rates in several jurisdictions. Choose the type that matches how the vehicle is registered.

Heavy vehicles never use a passenger-car rate. In NSW, a truck pays $3 per $100 of value. Western Australia charges 3% of the value, with duty capped at $12,000. Tasmania charges $1 per $100, and Queensland keeps heavy vehicles on its lower rate at any value.

The calculator applies a lower rate when you select a qualifying vehicle. Victorian green cars, with tailpipe emissions of 120 g/km of CO2 or less, pay $8.40 per $200 at any value. Victorian primary producer cars pay the same rate. Queensland hybrid and electric vehicles pay $2 per $100, or $4 per $100 of the whole value above $100,000. ACT vehicles rated AAA pay the zero-emission rate.

In the Northern Territory, the first $50,000 of a battery electric or plug-in hybrid vehicle's value is exempt until 30 June 2027. The exemption is worth up to $1,500, so a qualifying $80,000 vehicle pays $900. Exemptions for disability vehicles, family transfers and other special cases are outside this estimate.

Duty in a Vehicle Funding Position

Duty is one line in the purchase funds, separate from registration, compulsory third-party insurance and the transfer fee. The calculator adds the entered price, duty and costs. It then subtracts loan funds, the deposit and any trade-in.

For a hypothetical new car in NSW priced at $55,000, duty is $1,850. The calculation is $1,350 plus $5 for each of the 100 lots of $100 above $45,000. With $1,200 entered for registration and CTP insurance, the purchase costs $58,050. After $45,000 of loan funds and a $10,000 deposit, $3,050 is still needed.

For a hypothetical used car in Victoria bought for $28,000 with a $30,000 market value, duty is $1,260. Duty uses the higher market value, at $8.40 for each of 150 lots of $200. With a $50 transfer fee entered and no registration amount, the purchase costs $29,310. The price paid, not the market value, enters this total. After a $25,000 loan and a $3,000 deposit, $1,310 is still needed.

A dealer's drive-away price usually includes duty and registration. Enter the vehicle price without those charges so the calculator does not count them twice. If the funds entered exceed the total cost, the breakdown shows the excess funding.
