When Should You Register for GST/HST in Canada? (2026 Guide)

When Should You Register for GST/HST in Canada?

Introduction

If you're running a small business or freelancing in Canada, one of the most common questions is:

“When do I need to register for GST/HST?”

The answer depends on your revenue — but also on your business goals.

The $30,000 Small Supplier Rule

In Canada, you must register for GST/HST once your business earns:

$30,000 in revenue over 12 months

This includes:

  • Freelance income
  • Side hustle revenue
  • Business sales

Before that, you’re considered a small supplier.

What Happens If You Stay Under $30,000?

If you’re under the threshold:

  • You do not have to charge GST/HST
  • You do not need to register
  • You keep things simpler

This is ideal for new freelancers, side hustles, and early-stage businesses.

When You MUST Register

You are required to register if:

  • You exceed $30,000 in a 12-month period
  • You expect to exceed it soon
  • You run certain types of businesses (like ride-sharing)

Once registered:

  • You must charge GST/HST
  • You must file returns
  • You must track taxes collected

Should You Register Early?

Sometimes — yes.

Even if you're under $30,000, registering early can help you:

  • Claim input tax credits (ITCs) on expenses
  • Look more professional to clients
  • Prepare for growth

Example

You earn $20,000 but have $5,000 in business expenses.

Registering allows you to claim tax back on those expenses.

Common Mistakes

  • Waiting too long to register
  • Not tracking revenue properly
  • Forgetting the $30k rule is rolling, not calendar-based

  • Track revenue automatically
  • Know when you’re approaching $30,000

Final Thoughts

You don’t need to overcomplicate it.

Over $30k → required
