How stamp duty is worked out in NT
Territory Revenue Office charges it when a car is first registered and every time the registration moves to a new owner, private sale or dealer. For a sale between unrelated people, duty is on the price paid, including accessories, any trade-in and dealer delivery, GST included. Unlike the states, the Territory does not swap in a higher market value; it uses the market value only when there is no ordinary sale, such as a gift.
| Dutiable value | Duty |
|---|---|
| Any value | $3 per $100 or part of $100 of the whole value |
Concession: Electric and plug-in hybrid cars pay no duty on the first $50,000 of their value, until 30 June 2027.
The Territory's own duty calculator has no electric car option: for an electric or plug-in hybrid car, enter only the part of the price over $50,000 in it.

Transfer fee and rego in NT
The transfer fee is $22, and the buyer has 14 days from the sale to transfer the registration. A car over 7 years old needs a roadworthy inspection before the transfer. Rego carries over with the car until it expires, so you pay the next 12 months when it is due. Here is roughly what that costs.
