ITIN vs EIN for Non-Residents: Which One Do You Actually Need?
Eliminate confusion between US individual and business tax identifiers. Discover why most non-resident founders only need an EIN to launch their LLC, open bank accounts, and get approved for Stripe.
An EIN (Employer Identification Number) is a 9-digit business tax ID for your US LLC used for banking (Mercury, Wise) and Stripe payment processing. An ITIN (Individual Taxpayer Identification Number) is a personal tax ID for individuals filing US personal tax returns. To form an LLC, open a business bank account, and get Stripe, you ONLY need an EIN. An ITIN is NOT required.

Frequently Asked Questions: ITIN vs EIN
Do I need an ITIN to open an LLC and get Stripe?
NO. This is the most widespread misconception among foreign founders. You only need an EIN (Employer Identification Number) to open an LLC, establish commercial business bank accounts (Mercury, Relay, Wise), and activate Stripe. Your foreign passport serves as your individual identity verification.
When does a non-resident actually need an ITIN?
You need an ITIN only if you have a personal US tax filing requirement—such as receiving income with US tax withholding (like Amazon KDP royalties, US real estate rental income), claiming bilateral tax treaty benefits, or filing personal IRS Form 1040-NR to reclaim overwithheld taxes.
Can I use an EIN instead of an SSN on Stripe?
Yes. In the Stripe business application under 'Tax ID', you enter your LLC's EIN. Under the 'Personal Details' section for the account owner, you select 'I do not have an SSN' and provide your foreign passport number.
How fast can I get an EIN vs an ITIN?
An EIN can be obtained in 4–10 business days through HynoGo's expedited third-party-designee fax filing to the IRS Philadelphia Campus ($40). An ITIN takes 7 to 11 weeks because the IRS requires physical passport validation by a Certified Acceptance Agent (CAA) or mailing original documents to Austin, Texas.
Does getting an EIN make me a US tax resident?
No. An EIN is simply an administrative tracking number for your business entity. It has no bearing on your personal immigration or tax residency status.
