How the rule works

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.
