ITIN vs EIN for Non-Residents: Which Do You Need?

An EIN identifies your company. An ITIN identifies you as an individual. If you formed a US LLC as a non-resident, you almost certainly need an EIN, and you may never need an ITIN at all. The two are issued by the IRS on completely different forms, for completely different reasons, and one is not a prerequisite for the other.

Bottom line

• EIN: a business tax ID, free, applied for on Form SS-4, needed for banking, payment processors and every LLC filing.
• ITIN: a personal tax ID on Form W-7, only for individuals who must give the IRS a taxpayer number and cannot get a Social Security Number.
• You do not need an ITIN to get an EIN. Form SS-4 accepts “Foreign” where it asks for the responsible party’s SSN or ITIN.

ITIN vs EIN at a glance

Both are free directly from the IRS. Anyone charging you for “the government fee” on either number is charging you for their own labor, which is a legitimate thing to sell, but say so plainly.

What an EIN actually is

An EIN — Employer Identification Number — is a nine-digit number the IRS assigns to a business entity. Despite the name, it has nothing to do with having employees. It is the entity’s tax identity.

Your LLC needs one to do almost anything real. Banks will not open a business account without it. Stripe, PayPal, Amazon and every serious payment platform ask for it during onboarding. The IRS uses it to match your annual filings to your entity, and state agencies often want it too.

Non-residents cannot use the IRS online EIN assistant, because that tool validates the responsible party against an existing US taxpayer number before it issues anything. The paper route is the route. File Form SS-4, and where line 7b asks for the responsible party’s SSN or ITIN, the instructions direct applicants who have neither and are not eligible for either to write “Foreign”.

Fax it to the IRS international EIN unit — 304-707-9471 if you are faxing from outside the United States — or mail it to the EIN International Operation in Cincinnati. The full walkthrough, line by line, is in how to get an EIN without an SSN. Verify the current fax number on irs.gov before you send, because the IRS does move them.

What an ITIN actually is

An ITIN — Individual Taxpayer Identification Number — is issued to a person who needs a US taxpayer identification number for federal tax purposes but is not eligible for a Social Security Number. It is applied for on Form W-7.

It is a tax processing number and nothing more. It does not grant work authorization, does not affect immigration status, and is not a form of identification outside the tax system.

Two features of the W-7 process catch people out. First, the IRS generally expects Form W-7 to be filed together with the US tax return that creates the need for the number — you are usually not applying in a vacuum, you are applying because a return has to be filed. There are exception categories, and they are listed in the W-7 instructions; read them rather than assuming yours applies.

Second, the identity documentation is strict. The IRS wants an original passport or a copy certified by the issuing agency, not a photocopy you notarized locally. Many applicants use a Certified Acceptance Agent instead, precisely so they do not have to mail a passport to Texas and wait.

Who needs which: real scenarios

Single-member LLC, non-resident owner, no US-source income, no US tax return due from you personally. You need an EIN. You do not need an ITIN. Your LLC still has an annual information filing obligation — Form 5472 with a pro forma Form 1120 — and that is filed under the LLC’s EIN, not under your personal number.

You must file a personal US return. This is the main reason a non-resident founder ends up needing an ITIN: income that is genuinely US-source and requires Form 1040-NR, a treaty position you want to claim, or a US partnership that allocates income to you and withholds against it. No SSN, return required, so ITIN.

Your LLC is taxed as a partnership with foreign members. The partnership files Form 1065 and issues Schedule K-1s, and the IRS expects a taxpayer number for each partner. Foreign partners without SSNs typically end up needing ITINs. Plan for this before the first filing deadline, not after.

You elected corporate or S-corp treatment. Different filings, same principle: the entity files under the EIN; a human files under an SSN or ITIN when a human has to file.

You want an ITIN “for credit” or “to get a US bank account”. Neither is a good reason. Business banking runs on the EIN and the entity documents. Personal credit is a separate question with a separate answer, and applying for a tax number you do not owe a return under is not the path.

Whether you personally owe a US return is the actual question, and it depends on where the income is earned, what you do and where you do it. That is the one part of this you should not decide from an article. 1-800Accountant handles small-business federal filings and can tell you whether a personal return is in scope before you spend three months on a W-7 you did not need.

Five myths worth killing

“I need an ITIN before I can get an EIN.” No. This is the single most common misconception among founders forming from abroad, and it costs people months. Line 7b of Form SS-4 exists to handle exactly this case.

“The EIN makes me a US taxpayer.” No. An EIN is an identifier for the entity. Your personal tax exposure is determined by the tax rules, not by the existence of a number.

“An ITIN lets me work in the US.” No. The IRS is explicit that an ITIN does not authorize employment and does not change immigration status.

“Paying a service gets me the number faster.” Partly true for an EIN, in one narrow sense: a correctly completed form on the first attempt is much faster than two rejections. Nobody speeds up the IRS itself. Be skeptical of guaranteed turnaround claims.

“If I have no revenue, I have nothing to file.” Wrong, and expensive. A foreign-owned single-member LLC is generally required to file Form 5472 with a pro forma Form 1120 annually regardless of revenue, with penalties starting at $25,000. See US LLC taxes for non-residents and the annual compliance checklist.

Do it yourself or pay someone

Do the EIN yourself if your LLC is single-member, you are the responsible party, your entity name matches the state record exactly, and you have a fax option. It is one page and it is free.

Bundle it if you are also sorting out the state filing, the registered agent, a US address and the bank application, and you would rather the sequencing not break in the middle. doola packages formation, EIN and a US business address in one plan and handles the SS-4 as a designee. That is what you are paying for: fewer failure points, not IRS influence.

Pay a specialist for the ITIN if you have concluded you need one. The certified-document requirement is where do-it-yourself applications die, and a Certified Acceptance Agent exists to solve exactly that step.

FAQ

Can I get an EIN and an ITIN at the same time?

They are separate applications on separate forms with separate processing queues, so nothing stops you filing both, but there is rarely a reason to. Get the EIN first, because everything operational depends on it. Decide about the ITIN once you know whether a personal return is actually due.

Does my LLC need an ITIN to file Form 5472?

No. Form 5472 and the pro forma Form 1120 are filed by the LLC under its EIN. The form asks for identifying details of the foreign owner, and it accepts the situation where that owner has no US taxpayer number.

Will an ITIN expire?

ITINs can expire if they are not used on a federal return for several consecutive years, and renewal is its own submission. If you obtained one and then stopped filing, check its status before you rely on it.

Can my company be the responsible party on Form SS-4?

Line 7a wants a human being who ultimately controls the entity — an owner or managing member — not the company and not your registered agent. Your agent or accountant can appear as a third party designee if you sign that authorization.

The call

Get the EIN. It is free, it is one form, and nothing else in your US business works without it. Treat the ITIN as a conditional second step you only take if a US personal return is genuinely required of you.

This is general information, not legal or tax advice. Confirm your own position with a CPA or attorney who works with foreign-owned US entities before you file anything.

If you want the entity, the EIN and the address handled as one workstream, doola is the straightest line. If the entity already exists and the open question is what you owe and to whom, start with 1-800Accountant and get the answer before the deadline finds you.
