Understanding Quebec Sales Tax (GST and QST)

Quebec operates a dual-rate sales tax system consisting of the federal Goods and Services Tax (GST) and the Quebec Sales Tax (QST). The current rates are:

  • GST: 5.0% (Federal portion)
  • QST: 9.975% (Provincial portion)
  • Total Combined Rate: 14.975%

Unlike other provinces, Revenu Québec administers both the GST and QST within the province. Businesses operating in Quebec must register with Revenu Québec to report and remit both taxes.

The QST Calculation Shift (No Longer Compounded)

Prior to January 1, 2013, Quebec sales tax was calculated as a "tax-on-tax." QST was applied to the price of the item after the 5% GST was added, creating a compounded rate of 15.025%.

To align with international tax treaties and clean up calculations, Quebec eliminated compounding. Today, both GST (5%) and QST (9.975%) are calculated independently on the pre-tax base price, resulting in the clean 14.975% total.

Reclaiming QST (ITRs) vs. GST (ITCs)

Quebec businesses can recover the sales tax paid on business expenditures:

  • Input Tax Refunds (ITRs): Used to recover QST paid.
  • Input Tax Credits (ITCs): Used to recover GST paid.

Both are filed on the same return through Revenu Québec, but they must be reported in separate fields. Reverse calculations must isolate both components separately to ensure accurate recovery claims.

Frequently asked questions

Quick answers to the most common questions users ask.

What is the sales tax rate in Quebec?
Quebec charges a total combined sales tax rate of 14.975%. This consists of 5% Federal GST and 9.975% Provincial Sales Tax (QST).
Does Quebec support reverse tax calculation?
Yes. Select the 'Remove tax' (reverse) option in the calculator, input the total tax-inclusive paid amount, and the tool will automatically extract the pre-tax price and the tax component.
Who administers GST and QST in Quebec?
Under a unique federal-provincial agreement, Revenu Québec administers both the federal Goods and Services Tax (GST) and the provincial Quebec Sales Tax (QST) within Quebec. Businesses file a single combined sales tax return and remit payments directly to Revenu Québec.
What is the registration threshold for QST in Quebec?
The registration threshold is $30,000 CAD in worldwide taxable sales over four consecutive calendar quarters. Businesses must register through Revenu Québec's My Account portal once they cross this limit.
How do Quebec businesses recover GST and QST paid on business expenses?
Registered businesses recover the GST paid as Input Tax Credits (ITCs) and the QST paid as Input Tax Refunds (ITRs). Both are claimed in separate fields on the same unified tax return filed with Revenu Québec.
Is QST compounded on top of GST in Quebec?
No. Prior to January 1, 2013, QST was compounded (applied to the price after GST). Today, both the 5% GST and the 9.975% QST are calculated independently on the pre-tax base price, resulting in a flat combined rate of 14.975%.
Are books subject to Quebec QST?
Under Quebec's book rebate scheme, printed books and qualifying electronic publications are subject to the 5% federal GST but receive a point-of-sale rebate on the 9.975% QST, so only GST is charged at the register.
Are digital products sold by non-residents subject to QST?
Yes. Under Quebec's E-commerce QST scheme, non-resident digital suppliers and online platforms selling digital products, SaaS, or streaming services to Quebec consumers must register under the simplified QST system and collect 9.975% QST.
What are the sales tax rules for taxi and ride-sharing drivers in Quebec?
Ride-sharing and taxi operators in Quebec must register for both GST and QST from their first dollar of earnings; they do not qualify for the $30,000 small supplier exemption.
Are used vehicles purchased privately subject to QST?
Yes. Private sales of road vehicles are subject to the 9.975% QST, payable to the Société de l'assurance automobile du Québec (SAAQ) during transfer of registration, based on the higher of the purchase price or the average wholesale value.
When must a Quebec business file its QST returns?
QST return deadlines match the GST schedule. They must be filed monthly (due by the end of the following month), quarterly (due by the end of the month following the quarter), or annually depending on your volume.
Does QST apply to commercial rent in Quebec?
Yes. Commercial property leases in Quebec are subject to both 5% GST and 9.975% QST, which registered business tenants can recover as ITCs and ITRs.
