QST & CNESST GUIDE
Before you charge tax or hire in Quebec, you usually need to register with Revenu Québec for the QST (and GST/HST) and, once you have staff, with the CNESST. ClicSÉQUR-entreprises gives you secure online access to file and pay.
You must register for the QST once your worldwide taxable sales pass the $30,000 small-supplier threshold over four consecutive quarters — and often sooner if you want to claim input tax refunds. Most businesses register for QST and GST/HST at the same time. We confirm whether you need to register now.
As soon as you hire your first worker in Quebec, you must register with the CNESST, which covers workplace health, safety, and labour standards. Your business is classified by activity, and premiums are based on your payroll. We handle the registration and explain your obligations.

What is the QST?
The QST (Quebec Sales Tax, or TVQ) is the province’s 9.975% sales tax. If you sell taxable goods or services in Quebec, you generally register with Revenu Québec to charge, collect, and remit it — usually alongside the federal GST/HST.
When do I have to register for the QST?
Once your taxable sales exceed the $30,000 small-supplier threshold over four consecutive quarters, registration is mandatory. Many businesses register earlier so they can claim input tax refunds. We’ll confirm what applies to you.
What is CNESST registration?
The CNESST is Quebec’s workplace health, safety, and labour-standards board. Employers must register when they hire their first worker so employees are covered for workplace injuries. Premiums are based on your payroll and activity.
Do I need the CNESST if I have no employees?
Generally no — CNESST registration is triggered by hiring workers. Sole proprietors without staff usually aren’t required to register, though voluntary coverage is available. We’ll advise based on your situation.
What is ClicSÉQUR?
ClicSÉQUR-entreprises is Revenu Québec’s secure online authentication service. Your access code lets you file QST/GST returns, pay balances, and manage your business tax accounts online. We request and set it up for you.
Do I register for GST/HST and QST separately?
In Quebec, Revenu Québec administers both the QST and the federal GST/HST, so they’re usually registered together. We open both accounts at once so you’re ready to invoice.
How long does registration take?
Most QST, GST, and CNESST registrations are completed within one to three business days once we have your information. A ClicSÉQUR access code can often be requested the same day.
How much does it cost?
There’s no government fee to register for the QST, GST, or CNESST — you pay our fixed service fee to prepare and file everything correctly. We quote one price up front with no surprises.
What is the QST rate in Quebec?
The QST is 9.975%, applied on top of the 5% federal GST — a combined 14.975% on most taxable goods and services. We set up your accounts so you charge and remit the correct amounts.
Can a non-resident business register for the QST?
Yes. Non-resident and out-of-province businesses selling into Quebec may need to register for the QST. We’ll assess your obligations and handle the registration.
What do I have to file after registering?
You’ll file QST/GST returns on your assigned frequency, remit source deductions if you employ staff, and file an annual CNESST statement of wages. We can manage these filings so nothing is missed.
