No Professional Advice

The information and calculations provided on QuebecSalesTaxCalculator.ca are intended as a quick reference tool for everyday users. They are not a substitute for advice from a qualified tax professional, accountant, or lawyer. Before making any business decision, filing a tax return, or relying on a calculation for legal or financial purposes, please consult an appropriate professional.

Standard Cases Only

The calculator applies the standard Quebec sales tax treatment: 5% federal GST and 9.975% provincial QST on the subtotal of fully taxable goods and services. The following situations involve special rules that the standard calculator does not handle:

Used vehicle purchases (estimated value rules), real estate transactions (new housing rebates), insurance premiums (special tax rates), First Nations transactions (reserve-based exemptions), inter-provincial supply chains (place of supply rules), digital services from non-resident suppliers, and zero-rated or exempt supplies. For any of these situations, please consult Revenu Québec directly or speak with a tax professional.

Rate Currency

We update the calculator promptly when official rates change. However, there may be a brief delay between an announcement by Revenu Québec or the CRA and our update. Always verify the current rate against the official source for any high-stakes calculation.

No Affiliation

QuebecSalesTaxCalculator.ca is an independent informational website. We are not affiliated with, endorsed by, or sponsored by Revenu Québec, the Canada Revenue Agency, the Government of Quebec, or the Government of Canada.
