Do you need an SSN or ITIN to open a US business bank account

Many foreign owners are told they need an SSN or ITIN before any US bank will open an account for their LLC. The federal rules say otherwise, but banks can set stricter policies. This guide explains the rules and what that means when you apply.

Short answer

No federal rule requires an SSN or ITIN to open a US business bank account. The account belongs to the LLC and uses its EIN. For owners who are not US persons, federal rules let banks accept a passport number, an alien identification number or another government-issued photo ID number instead of a taxpayer number. Some banks still require an SSN or ITIN as their own policy.

Whose number does the account use?

A business account for an LLC is opened in the LLC's name, using the LLC's EIN. The owners' numbers matter only for the bank's checks on the people behind the company. See does a single-member LLC need an EIN.

What do the federal rules require?

US banks must run a customer identification program and identify the beneficial owners of business accounts. For each person, the bank collects a name, date of birth, address and an identification number:

  • For a US person: a taxpayer identification number, meaning an SSN or ITIN.
  • For a person who is not a US person: one or more of a taxpayer identification number, a passport number and country of issue, an alien identification card number, or the number and country of issue of another government-issued document showing nationality or residence and bearing a photograph.

So a non-US owner can be identified with a passport. Nothing in these rules requires an SSN or ITIN.

Why do some banks still ask?

The federal rules set the minimum. Banks can require more. Some ask for an SSN or ITIN from every owner because their systems, fraud checks or partner banks are built around US numbers. That is a policy choice, and it varies from one bank or provider to the next.

Should you get an ITIN for the bank?

You cannot, for that reason alone. The IRS issues ITINs only for a federal tax purpose, usually a return you must file. See can you get an ITIN without filing a tax return. If a bank insists on one and you have no tax reason, look for a provider that accepts a passport.

How should you apply?

  1. Check the provider's rules first

    Look for whether it accepts owners without an SSN or ITIN, and owners from your country.

  2. Use your passport as your ID

    And have proof of your home address.

  3. Give the LLC's EIN as the account's tax number

    With the EIN confirmation. See documents banks ask for.

  4. Provide the right tax form

    Usually the owner's Form W-8BEN for a foreign-owned single-member LLC. See Form W-8BEN.
