How To Register With The CRA As A Non-Resident Business (Step-by-Step For U.S. Companies)

Non-Resident Business Registration (Canada) The CRA process for a business located or incorporated outside Canada to obtain a Business Number and eligible CRA program accounts.

This how-to focuses on practical steps a U.S. or other foreign business should follow to register with the Canada Revenue Agency and obtain a Business Number (BN) and any required program accounts. The goal is to reduce surprises: prepare documents, choose the right accounts, and use CRA channels efficiently.

Step 1 — Confirm You Need To Register

Before starting, evaluate your Canadian activities against CRA triggers: Are you making taxable supplies to Canadian customers? Do you have employees working in Canada? Are you importing goods into Canada? If the answer to any is yes, determine which CRA program accounts (GST/HST, payroll, import) apply.

Step 2 — Gather Required Documents

Collect standard documentation to prove identity and activity. Typical items include:

• Corporate formation documents: Articles of incorporation, certificate of good standing, or foreign equivalents.
• Foreign tax ID: U.S. EIN or other foreign business number.
• Proof of activity: Contracts, purchase orders, quotations, or invoices showing Canadian customers.
• Representative info: Contact details for an authorized officer and, if used, a Canadian agent or representative.

Step 3 — Choose Registration Channel

You can register a BN and program accounts in several ways:

• Online (limited): The CRA’s online services support many registrations but non-resident situations may require phone or paper forms.
• Phone: Call the CRA Business Enquiries line and explain you are a non-resident needing a BN — the CRA has specific routing for foreign businesses.
• Mail or fax: Submit a completed RC1 form (or equivalent CRA forms) with documents when requested. The RC1 is the CRA’s application for a BN.

Step 4 — Specify Program Accounts

When applying, state clearly which accounts you need. Common choices and considerations:

• GST/HST (RT): Required if making taxable supplies and meeting registration criteria; optionally registered voluntarily to recover input tax credits.
• Payroll (RP): If you will pay employees in Canada or employees perform work in Canada.
• Import/Export (RM/RX): If you will clear goods through customs; coordinate with CBSA for import duties and accounting.

Step 5 — Provide A Canadian Address Or Representative If Needed

The CRA sometimes requests a Canadian mailing address or a Canadian representative to receive legal notices. This can be a Canadian office, lawyer, accountant, or customs broker. If you appoint an agent, have a signed authorization available to provide to the CRA.

Step 6 — Understand Ongoing Filing And Remittance

Once the BN and accounts are active, observe filing cycles and remittance deadlines. Examples:

• GST/HST returns: Frequency (monthly, quarterly, annually) depends on your taxable supplies volume.
• Payroll remittances: Withhold and remit income tax, CPP, and EI according to Canadian payroll rules and schedule.
• Customs reporting: Maintain import paperwork and reconcile duties and GST paid at importation.

Common Pitfalls And How To Avoid Them

U.S. companies often face similar mistakes:

• Underestimating thresholds: Failing to register because of incorrect assumptions about tax thresholds — get a correct determination from the CRA.
• Poor documentation: Not keeping contracts, invoices, and import records that support your registration and filings.
• Neglecting provincial rules: Some provinces have separate filings (e.g., QST in Quebec); registration at the federal level doesn’t automatically solve provincial obligations.

Practical Example — A U.S. E‑commerce Seller

An online retailer in the U.S. sells consumer goods to Canadian customers and ships from the U.S. If it collects enough taxable supplies, it should register for a BN and GST/HST account; the BN will also be used by a customs broker if the seller requires a third party to clear imports. The seller must decide whether to collect GST/HST at checkout or remit tax under a marketplace model; contracts and marketplace rules determine who is the registrant and remitter.

In short, the Non-Resident Business Registration (Canada) process starts with confirming registration need, collecting formation and activity documents, choosing the correct CRA channel, and setting up the BN and program accounts required for GST/HST, payroll, and import/export compliance. Proper preparation reduces delays, supports claimable input tax credits, and keeps cross-border operations running smoothly.
