Questions people ask

How much is stamp duty on a $40,000 car?

In NSW, Queensland (4 cylinders), the ACT (150 g/km) and the NT it is $1,200. Victoria charges $1,680, South Australia $1,540, Tasmania $1,600 and Western Australia $2,000, because WA's rate rises from 2.75% to 6.5% between $25,000 and $50,000.

Is stamp duty charged on the price including GST?

Yes. Duty is worked out on the price you pay including GST (and luxury car tax on a new car), or the market value if that is higher, for example on a used car bought cheaply or a gift.

Do electric cars pay less stamp duty?

In some places. Queensland charges $2 per $100 instead of $3 or more, Victoria treats electric cars as green cars at $8.40 per $200 at every price, the ACT has its lowest emissions band, and the NT waives duty up to $50,000 until 30 June 2027. NSW, South Australia, Tasmania and Western Australia charge the same as for petrol cars.

Which state has the highest car stamp duty?

It depends on the price. Western Australia is the most expensive for mid-priced cars (6.5% above $50,000), while Victoria is highest for luxury cars because $18 per $200 (9%) applies to the whole value above $150,000.

When do I pay car stamp duty?

When you register a new car or transfer the registration of a used one, usually within 14 days of buying it. Dealers normally collect it as part of the drive-away price.
