Do I need to charge HST/GST?
Just starting out in Canada? Enter your revenue and province to see whether you've passed the $30,000 small-supplier threshold — the point where you have to register for GST/HST and start charging tax. No signup, nothing saved.
How the rule works
- Under $30,000 in taxable revenue over four rolling quarters → you're a small supplier. You don't have to register or charge GST/HST (but you can register voluntarily to claim ITCs).
- Over $30,000 across four quarters → you must register and charge GST/HST on your taxable sales.
- Over $30,000 in a single quarter → you stop being a small supplier that day and must register immediately.
Frequently asked
What is the $30,000 small-supplier threshold?
If your total taxable revenue (before expenses) is $30,000 or less over four consecutive calendar quarters, you're a 'small supplier' and don't have to register for GST/HST. Once you go over $30,000, you have to register and start charging tax.
Is it four quarters or a single quarter?
Both matter. You must register if your revenue exceeds $30,000 over the last four consecutive quarters combined. But if you exceed $30,000 in a single calendar quarter, you stop being a small supplier that day and must register immediately.
Should I register voluntarily even under $30,000?
You can. Registering lets you claim input tax credits (ITCs) — the GST/HST you paid on business purchases — back from the CRA. It's often worth it if you have significant taxable expenses or sell mostly to other registered businesses.
What about PST or QST?
GST/HST is federal. Provinces like BC, Saskatchewan, and Manitoba have their own PST/RST, and Quebec has QST — those are separate registrations with their own rules. This checker covers the federal GST/HST registration question.
