How a non-resident owner gets an EIN from the IRS without a Social Security Number

What to take away

Why the IRS asks for an SSN and what a foreign owner can use instead

The EIN belongs to the entity. The responsible party line belongs to the person who controls it.

For a US owner, that line takes a Social Security Number. A non-resident owner has none, so the same line takes a foreign taxpayer identification number, or the word "Foreign" where the form allows it. The IRS accepts a passport number, a national ID number, or an ITIN in that spot.

The online EIN application asks for a valid SSN, EIN or ITIN for the responsible party and checks it against IRS records in real time. A foreign passport number fails that check, which closes the online route to most non-resident owners.

The IRS says as much on its own page about obtaining an EIN for entities whose responsible party holds no US number. Paper is the route that works.

One detail trips people up: a US LLC with a US address can still have a foreign responsible party. The address does not pick the channel. The responsible party's identification does.

If you are still choosing what to form, the order matters, and the notes on LLC formation cover what to keep and what to drop. The EIN comes after the state approves the entity, not before.

Form SS-4 line by line: responsible party, entity type and the no-SSN boxes

Three lines cause most of the trouble on the paper form. Line 7b is the responsible party's SSN or ITIN. Line 8a asks whether the entity is a sole proprietorship. Line 9 asks for the entity type.

On line 7b a foreign owner writes "Foreign," then supplies the country and the identifying number. The instructions for Form SS-4 require that the number match the name on the ID document you can produce if asked.

Line 8a matters more than people expect. A single-member LLC owned by one foreign person is a disregarded entity by default, and the IRS treats the owner as the taxpayer. Check the box that matches reality, not the one that sounds simpler.

Line 9 has a separate checkbox for a limited liability company, followed by the number of members and whether the LLC is domestic or foreign. A US-registered LLC is domestic here even when every member lives abroad.

The paper Form SS-4 runs four pages including instructions, and the IRS charges no fee. Anyone quoting you a government fee for the EIN itself is describing something else.

The W-7 and ITIN route when the IRS will not issue an EIN without one

Sometimes the IRS returns the SS-4 and asks for an ITIN before it assigns the EIN. That happens most often with multi-member LLCs, with entities that file their own returns, and with owners who already have US filing obligations.

The fix is Form W-7, the ITIN application, filed with the IRS alongside your first federal return or on its own, with identity documents or certified copies from the issuing agency.

A passport is the cleanest W-7 document because it stands alone as proof of identity and foreign status. Send the original and the IRS returns it, but the processing adds weeks. Certified copies from your passport office avoid that wait.

The ITIN belongs to you as an individual. It does not replace the EIN for the LLC and does not make you a US resident for tax purposes. It gives the IRS a number to attach to your name.

Apply for the EIN first with your foreign ID. File a W-7 only if the IRS asks, because an unnecessary ITIN application adds months to a process that otherwise takes weeks.

Keep a copy of everything you send. If the W-7 and the SS-4 are in the mail at the same time, the IRS can process them in either order, and a lost document is far easier to replace when you hold the copy.

Fax, phone and mail: which EIN application channel actually works from abroad

The IRS offers four channels: online, fax, phone and mail. For a non-resident owner the online channel is usually unavailable and the phone channel is closed. That leaves fax and mail.

Fax is faster. The IRS returns an EIN by fax in about four business days when the application is complete. Mail runs four to six weeks, and international post adds transit time in both directions.

The IRS publishes separate fax numbers for domestic and international filers, and the numbers change. Check the current Form SS-4 instructions before you send rather than trusting a number from an old blog post. A fax to a retired line looks identical to a fax that was never sent.

Some services handle the filing for you, and the comparison of EIN applications tools covers what to look for. Whatever channel you choose, the confirmation letter is the document that matters afterward.

Documents a non-resident owner must send with the SS-4 package

A complete package is short, but every piece gets checked. Missing one item is the most common reason a foreign-owned LLC waits a month for a number it could have had in a week.

The instructions for Form W-8BEN explain that the form goes to US payers and banks, not to the IRS. It certifies your foreign status and any treaty claim, and it is separate from the EIN application.

A bank opening an account for a foreign-owned LLC will usually ask for the EIN, the formation documents, the operating agreement, and a W-8BEN from each owner. Expect the bank to want certified copies, not scans.

Some states add their own paperwork. A Delaware LLC needs its registered agent and franchise tax obligations handled, and a Wyoming or Nevada LLC has annual report duties. None of that changes the federal EIN package, but a bank may ask to see proof that the state filings are current.

Keep the whole package in one folder, digital and physical. When the IRS asks a follow-up question, and it sometimes does, you answer with a document you already have rather than one you must request from another country.

Common EIN application mistakes that stall a foreign-owned LLC

A blank responsible party line stalls the application immediately. The IRS cannot assign the number without knowing who controls the entity, and "the manager" is not a name.

An unsigned form is the second most common failure. A typed signature or a scanned signature block does not count on the paper form. Sign after printing, in ink.

Wrong entity type is third. A single-member LLC that checks the corporation box, or a multi-member LLC that checks sole proprietor, gets a letter asking for correction instead of an EIN. That exchange can add a month.

Faxing to the wrong number is fourth, and it is invisible. Nothing bounces back. You wait, hear nothing, and assume the IRS is slow when the form never arrived.

Applying before the state approves the LLC is fifth. The SS-4 asks for the formation date and the state of formation. Filing early means guessing, and a guess that does not match the state record creates a mismatch.

Keeping no copy of what you sent is sixth. When the IRS asks a question, you need to know exactly what was on the form. The EIN applications checklist covers the items worth keeping, and the EIN application mistakes notes rank the failures by how long they cost you.

Finally, remember what the number is. EIN applications produce an identifier, and the entity comes first, so a perfect EIN for a badly formed LLC solves nothing. Fix the formation, then file.

Common questions

Can a non-resident get an EIN without an SSN or ITIN?

Yes. File paper Form SS-4 by fax or mail and write "Foreign" on line 7b with your passport or national ID number. The online portal will not accept a foreign ID, so it is not an option for most non-resident owners.

Is an ITIN required before the IRS issues an EIN?

Usually not. The IRS accepts a foreign identification number for the responsible party. An ITIN via Form W-7 is needed only when the IRS specifically asks, which happens more often with multi-member LLCs.

Which fax number does a foreign applicant use?

The IRS publishes separate fax numbers for domestic and international filers, and they change over time. Check the current Form SS-4 instructions on the IRS site before you send, and keep the fax confirmation page.

How long does an EIN take for a foreign-owned LLC?

A complete fax application typically returns an EIN within about four business days. Mail takes four to six weeks, longer with international post. An incomplete form resets the clock.
