Purchase or Sale of a Used Vehicle – Change to QST Rules

If you’re an individual

Effective January 1, 2025, when you buy or sell a used motor vehicle that’s 14 years old or less, the QST will be calculated on the vehicle’s estimated value if this is higher than the agreed sale price.

Whether you buy a used vehicle from an individual you’re not related to or from a dealer, the QST is always collected by the Société de l’assurance automobile du Québec when the vehicle is registered.

Sale between related individuals

The estimated value rule does not apply to sales of road vehicles between related individuals. 

In a used road vehicle transaction between related individuals, the QST is calculated on the agreed sales price. Since March 13, 2024, the same holds true when bringing a used road vehicle into Québec following a transfer between related individuals that took place outside of Québec.

If you’re a dealer

Effective January 1, 2025, when you sell a used motor vehicle that’s 14 years old or less, you must calculate the QST on the vehicle’s estimated value if this is higher than the agreed sale price.

For a vehicle’s estimated value, see the Guide d’évaluation Hebdo (automobiles et camions légers), published by Trader Corporation. The guide currently shows the average wholesale price of vehicles for the last 9 years. As of January 1, 2025, an online version of the guide will show the average wholesale price for the last 14 years.
