ITIN for Canadian Residents with US Bank Accounts — Complete Guide 2026

By ITIN Plus Inc.  |  Updated September 2026  |  8 min read

Quick Answer Canadian residents opening a US business bank account (Mercury, Relay, Wise) typically need an EIN ($50, 1–2 weeks) — not necessarily an ITIN. For personal US accounts or IRS tax filing obligations, an ITIN ($99, 8–14 weeks) is required. Many Canadian LLC owners need both.

Do Canadian Residents Need an ITIN to Open a US Bank Account?

This is the most common question we receive from Canadian residents forming US LLCs or receiving US income. The answer depends on two things: the type of account (personal vs. business) and the bank itself.

The short version: business accounts at modern US online banks usually only require an EIN for the LLC — your personal ITIN is not required at account opening. Personal accounts at traditional US banks typically require an ITIN as a non-resident tax ID.

The Recommended Order for Canadian LLC Owners

  1. Form your US LLC — Delaware or Wyoming are most popular for Canadians (no state income tax for non-resident owners, strong legal protections).
  2. Get your EIN first ($50, 1–2 weeks) — You need the EIN to open a US business bank account. ITIN Plus processes EIN applications in 1–2 weeks.
  3. Open your US bank account — Use Mercury, Relay, or Wise Business with your EIN + LLC formation documents + Canadian passport.
  4. Apply for your ITIN ($99, 8–14 weeks) — You need this for your annual Form 1040-NR filing as the LLC owner, and to claim Canada-US treaty benefits on your W-8BEN.
  5. File Form 5472 — Foreign-owned US single-member LLCs must file Form 5472 (informational return) with the IRS annually. This requires your EIN. ITIN Plus can assist with this filing.

Canada-US Tax Treaty — How It Affects Your US Bank Account

The Canada-US Tax Convention (tax treaty) affects withholding on income, not bank account eligibility. Here's how it applies to Canadian residents with US accounts:

This means: even if your bank only required an EIN to open your account, you will want an ITIN to submit a W-8BEN and claim treaty-reduced withholding rates on income earned in or from that account.

Frequently Asked Questions

Do Canadian residents need an ITIN to open a US bank account?

For business accounts at online banks (Mercury, Relay, Wise), typically no — an EIN for your US LLC is sufficient. For personal accounts at traditional US banks, yes — an ITIN is generally required for non-resident account holders.

Can a Canadian open a US bank account without an ITIN?

Yes, for business accounts. Mercury, Relay, and Wise Business open accounts for US LLCs owned by Canadians with just an EIN + passport. Traditional banks like Bank of America and Chase usually require an ITIN for non-residents.

What is the difference between ITIN and EIN for Canadian LLC owners?

EIN is for your US business entity (LLC). ITIN is your personal tax ID. You need an EIN to open a US business bank account and file LLC taxes. You need an ITIN to file your personal 1040-NR and claim Canada-US treaty benefits on your W-8BEN.

How long does it take for a Canadian to get an ITIN?

8–14 weeks from IRS submission. An EIN takes 1–2 weeks. If you need banking quickly, get the EIN first, then apply for the ITIN for your ongoing tax compliance needs.

Does the Canada-US tax treaty help with US bank accounts?

Indirectly — yes. The treaty doesn't affect account eligibility, but once you have an ITIN, you can submit W-8BEN with treaty claims to your bank, reducing withholding on interest, dividends, and other income to treaty-reduced rates (often 0% on interest, 15% on dividends).
