The Quebec sales tax, handled by a CPA
The Quebec sales tax (QST) is the provincial consumption tax that applies to most goods and services supplied in Quebec. It is calculated at a rate of 9.975 percent on the selling price, after the GST is excluded from that price. Revenu Quebec administers the QST, and it also administers the GST and HST within Quebec. We handle the full filing, from preparing your return to remitting what you owe, so your QST is prepared and filed by a Chartered Professional Accountant (CPA).
Rate and administration confirmed on Revenu Quebec, Basic Rules for Applying the GST/HST and QST.
Do you need to register for QST?
The small supplier threshold
You are considered a small supplier if your worldwide taxable supplies, together with those of your associates, do not exceed $30,000 in a calendar quarter or over the four preceding calendar quarters. A small supplier is not required to register for or collect the GST and QST.
Once you cross $30,000
When your taxable supplies pass the $30,000 threshold, registration becomes mandatory and you must start collecting and remitting QST. Some businesses are also required to register regardless of revenue, depending on what they sell.
Registering voluntarily can pay off
Even as a small supplier you can register by choice. Doing so lets you claim input tax refunds on the QST you pay to run your business. If you register for the QST, you must also register for the GST.

Book your free consultationHow QST works alongside GST and HST
In Quebec the GST applies at 5 percent and the QST applies at 9.975 percent, and most businesses collect both on the same sale. When you sell into Ontario or another HST province, the HST replaces the separate GST and provincial tax instead. We keep these layers straight on every invoice and return, and because we also handle your HST and GST filing, your sales taxes are reconciled together rather than in silos.
QST also connects to the rest of your Quebec obligations. We prepare Quebec personal tax returns and Quebec corporate tax (CO-17) filings, and you can see the full picture across all our tax services.
