Which sales count toward the threshold?

Worldwide taxable supplies, including zero-rated ones, for you and associated persons. Some items, such as certain financial services and capital property sales, are left out; check the CRA page for the full rule.

Does the same threshold apply to charities?

No. Charities and public service bodies have different thresholds. This checker covers the general small-supplier rule only.

Should I register voluntarily?

It can make sense when you buy a lot of taxable inputs, because registrants can claim input tax credits. Talk to your accountant.

No. The check runs in your browser and nothing is sent anywhere.

Check the small-supplier threshold

Enter your worldwide taxable supplies (C$) for the last four consecutive calendar quarters, oldest first.

Oldest quarter (C$)Next quarter (C$)Next quarter (C$)Most recent quarter (C$)

Four-quarter total	C$33,000.00
Small-supplier threshold	C$30,000.00

The four quarters together are over the threshold (crossed in quarter 4). CRA says you stop being a small supplier at the end of the month after that quarter, and must register within 29 days of the effective date.

Guidance only. Some supplies are left out of the test and charities and public service bodies have different rules; check the CRA page on when to register.

The two CRA tests

You are a small supplier while your worldwide taxable supplies stay at or under C$30,000.00 over four consecutive calendar quarters. Small suppliers do not have to register, though they may register voluntarily.

If you go over C$30,000.00 in a single calendar quarter, CRA says you must register and charge GST/HST starting with the sale that takes you over. If you go over it across several quarters but not in one, you stop being a small supplier at the end of the month after the quarter in which you crossed it.

Once registration is required, CRA expects you to register within 29 days of the effective date.
