Few things confuse non-resident founders more than US tax IDs. You’ve heard you need an EIN, then someone mentions an ITIN, and suddenly you’re worried you’re missing a document that will block your bank account. The ITIN vs EIN question has a clear answer, and for most LLC owners it’s simpler than you fear: you need an EIN, and you probably don’t need an ITIN at all.
This guide settles ITIN vs EIN for good — what each one is, who genuinely needs which, the correct order to get them, and how to avoid paying for a document you’ll never use.

ITIN vs EIN: the one-line difference
An EIN identifies your business. An ITIN identifies you personally. That’s the whole distinction, and almost every mistake comes from blurring it.
| EIN | ITIN | |
|---|---|---|
| Stands for | Employer Identification Number | Individual Taxpayer Identification Number |
| Belongs to | Your LLC (the entity) | You (the human) |
| Format | 12-3456789 | 9XX-XX-XXXX |
| Applied for with | Form SS-4 | Form W-7 |
| Cost from the IRS | Free | Free |
| Needed to open a US bank account | Yes | No |
| Needed for Stripe / PayPal | Yes | No |
| Needed for Form 5472 | Yes | No |
| Needed to file a personal US return | No | Yes |
ITIN vs EIN: what the EIN does for you
The EIN is your LLC’s tax identity and the key that unlocks nearly everything: your US business bank account, Stripe and PayPal, Amazon and Etsy seller accounts, wholesale supplier accounts, and your annual Form 5472 filing.
Crucially for the ITIN vs EIN decision: you do not need an SSN or an ITIN to get an EIN. The IRS has a dedicated process for international applicants who have neither — you file Form SS-4 by fax or mail, leaving the responsible-party ID field marked “Foreign”. Our EIN without an SSN guide covers the exact steps. Anyone telling you an ITIN is a prerequisite for an EIN is wrong.
ITIN vs EIN: when you actually need an ITIN
An ITIN exists for one purpose: so a person without an SSN can meet a personal US tax obligation. You need one if:
- You must file a personal US tax return (Form 1040-NR). This happens when you have US-source income that’s actually taxable to you — for example, income effectively connected with a US trade or business, or US rental property.
- You’re claiming a tax treaty benefit on US-source income and need to identify yourself to the IRS.
- Your LLC is a multi-member partnership that issues you a Schedule K-1 — partners generally need a US tax ID.
- A withholding agent or platform requires a valid W-8BEN with a US TIN to reduce withholding on certain payments (royalties are the classic case).
- You’re electing corporate treatment or otherwise entering the US tax system personally.
Notice what’s absent from that list: opening a bank account, using Stripe, selling on Amazon, and filing Form 5472. None of those require an ITIN.
The typical non-resident: EIN only
Here’s the profile that fits most of our clients. You own a single-member US LLC, treated by the IRS as a disregarded entity. You live outside the US, have no US office, no US employees, and no dependent agents there. You sell services or products to customers, some of them American.
In that situation the LLC files Form 5472 with a pro forma 1120 using its EIN, you have no personal US filing obligation, and you owe no US federal income tax (the tax guide explains the reasoning). So the ITIN vs EIN answer for you is: EIN, full stop. Getting an ITIN “just in case” adds a US tax identity you don’t need and a filing footprint you didn’t ask for.
ITIN vs EIN: the correct order to apply
Once you understand ITIN vs EIN, the sequence that works is straightforward:
- Form the LLC in New Mexico or Wyoming.
- Get the EIN via Form SS-4 as an international applicant — no SSN or ITIN needed.
- Open your US bank account with the LLC documents plus EIN letter.
- Start operating — Stripe, PayPal, marketplaces, suppliers.
- Get an ITIN via Form W-7 only if and when a genuine personal filing obligation appears — and you can file W-7 together with the return that requires it.
The expensive mistake is reversing steps 2 and 5: waiting months for an ITIN before applying for your EIN, because someone said you needed a “personal tax number first”. You don’t. That delay costs real revenue while your business sits unable to bank or accept payments.
How the ITIN application works, if you need one
You file Form W-7 with proof of identity and foreign status — normally a certified copy of your passport — plus the US tax return or treaty documentation that creates the need. You can mail it to the IRS, use an IRS-authorised Certifying Acceptance Agent (which avoids mailing your original passport), or apply at a US consulate offering the service. Processing typically runs several weeks to a few months, longer in peak season. The IRS charges nothing; agents charge for their service.
Frequently asked questions
Do I need an ITIN to open a US business bank account?
No. Mercury, Wise, and Relay verify you with your passport and verify your company with its EIN and formation documents. No ITIN is requested. See our bank comparison.
Do I need an ITIN for Stripe or PayPal?
No. Both onboard your business with the LLC’s EIN. What actually gets applications approved is a consistent profile — matching US entity, EIN, bank account, address, and a US phone number.
Can I use my EIN instead of an ITIN on a W-8BEN?
No — they’re not interchangeable. A W-8BEN is a form about you as an individual, so the US TIN box is for an ITIN (or SSN). A W-8BEN-E is the entity version, which uses the EIN. Using the wrong form is a common reason platforms reject tax documentation.
Does having an ITIN mean I owe US tax?
An ITIN by itself creates no tax liability — it’s an identifier, not a status. But you should only obtain one because a filing obligation exists, and that obligation is what determines any tax owed.
In ITIN vs EIN terms, is an ITIN the same as an SSN?
No. An ITIN is only for tax filing. It grants no work authorisation, no immigration status, and no Social Security benefits.
