GST/HST Registration

GST/HST registration terms covering small-supplier status, account setup, and when a business enters the sales-tax system.

This subsection covers the GST/HST terms that usually appear before a return is filed.

What Belongs Here

Use this subsection when the question is about whether a business must register, what a GST/HST account is, or how sales-tax administration begins.

This is the right home when the practical issue is:

  • whether the business is still a small supplier
  • when GST/HST collection has to start
  • what CRA account exists once the business enters the system

  • Start with Small Supplier if the first question is whether registration is required.
  • Start with GST/HST Account if registration already happened and the next question is what account or filing structure exists.
  • Move to Filing and Input Tax Credits once the issue becomes return filing, input tax credits, or net tax.
