GST/HST Registration: When a Freelancer Has to Register

Most freelancers don’t need to register for GST/HST right away. You’re classified as a small supplier — and don’t have to register or charge GST/HST — as long as your revenue stays under the threshold below. Once you cross it, registration stops being optional.

The $30,000 threshold

The CRA tests this two ways, and either one can trigger mandatory registration:

1. Single-quarter test — if your worldwide taxable supplies (your revenue from sales, including zero-rated sales) exceed $30,000 in any one calendar quarter, you stop being a small supplier immediately. You have to start charging GST/HST on the sale that pushed you over, and register within 29 days.
2. Rolling four-quarter test — if your total revenue across the last four consecutive calendar quarters exceeds $30,000, the same applies, even if no single quarter on its own was over $30,000.

The threshold is $30,000, not $50,000 — $50,000 is a separate, higher threshold that applies only to public service bodies (charities, non-profits, municipalities, universities), not to freelancers or typical small businesses.

What counts toward the $30,000

Your total revenue from taxable and zero-rated supplies, worldwide — not just GST/HST-taxable sales within Canada. If you also have any associated businesses (a holding structure, a partnership you’re a part of), their revenue counts too; the threshold applies to the group, not just to you individually.

Registering voluntarily, before you hit the threshold

You can register before you’re required to. The main reason freelancers do this: once registered, you can claim input tax credits (ITCs) — recovering the GST/HST you pay on business purchases (software subscriptions, equipment, a portion of home-office costs). If your business expenses are significant relative to your revenue, voluntary early registration can be worth it even below $30,000. The tradeoff is that you then have to charge, collect, and remit GST/HST on everything you sell, and file returns on a schedule the CRA assigns you.

What changes once you’re registered

• You must charge GST/HST on your taxable supplies, at the rate that applies to where the supply is made (GST alone in a non-participating province, HST where it applies, or GST+PST in provinces that haven’t harmonized)
• Your invoices need to show your registration number and the tax clearly labelled — see the GST invoice template
• You file GST/HST returns (most small businesses are assigned an annual filing period, though you can request quarterly or monthly) and remit what you collected, net of any ITCs

This is general information, not tax advice. GST/HST rules and thresholds can change — verify your specific situation against the CRA source linked above or with an accountant before deciding whether or when to register.
