GST / QST Sales Tax
In Quebec, sales tax means two regimes: the 5% GST and the 9.975% QST, 14.975% combined. We register you, file both on schedule and make sure every input tax credit and refund you are entitled to is claimed.
Everything handled, nothing left hanging
- GST and QST registration
- Monthly, quarterly or annual GST/QST returns

A check that you are on the most favourable method.
Common questions
When must I register for GST and QST?
Once taxable revenue passes $30,000 over four consecutive calendar quarters. Registering earlier can make sense, and we will tell you if it does.
I sell outside Quebec. What do I charge?
It depends on where your customer is. Sales to other provinces may attract HST or GST instead of QST. We set up the rules in your software so every invoice is right.
