Explain the sales tax on vehicle purchases in QC?

In Quebec, vehicle purchases are subject to a dual sales tax system: the federal Goods and Services Tax (GST) at 5% and the Quebec Sales Tax (QST) at 9.975%, resulting in a combined rate of 14.975%. This structure is unique compared to provinces with a Harmonized Sales Tax (HST) and applies to the vast majority of vehicle transactions within the province.

For new vehicles and used vehicles purchased from a registered dealer, both the 5% GST and 9.975% QST are applied to the full purchase price before any trade-in value is considered. However, a significant provincial nuance applies to used vehicles purchased from a private seller: only the 9.975% QST is applicable, and the buyer is personally responsible for remitting this QST directly to Revenu Québec. This distinction is critical for consumers to understand, as the source of the vehicle directly impacts their tax liability and payment process.

Understanding these tax implications is paramount for consumers, as sales tax represents a substantial addition to the vehicle's advertised price, directly impacting affordability and financing requirements. Furthermore, federal and provincial rebates, particularly for electric vehicles, can significantly reduce the net cost, often by being applied before tax calculations or as a post-purchase credit, making it essential to factor these into the total financial picture. Always confirm the exact tax treatment and any applicable rebates with the seller or relevant government agencies to ensure accurate budgeting.
