Frequently Asked Questions
When do I need to register for GST/HST?
You must register once your revenue exceeds $30,000 over four consecutive quarters. Below that threshold, registration is voluntary.
Do I charge GST or HST?
It depends on the province where the supply is made. HST provinces (ON, NS, NB, NL, PE) have a single combined rate. Others charge GST + provincial PST separately.
