Form SS-4 without an SSN: line by line for a foreign-owned LLC

How to fill in Form SS-4 when the owner has no SSN: what goes on lines 7b and 9a, the rest of the form, and where to fax or call the IRS from abroad.

Updated by the BaseAcross team. Reviewed by Saais Patel, compliance reviewer, against the sources named in the text.

The short answer

Form SS-4 is the one-page IRS application for an EIN, and for a company owned from abroad two lines decide most of it. On line 7b, where the owner's tax number goes, you write "foreign" or N/A if the owner has no SSN or ITIN. On line 9a, a single-member LLC checks Other and writes "Foreign-owned U.S. disregarded entity-Form 5472". Then you fax the form to the IRS's international number, or call its international line and get the EIN during the call. Here's every line, with the answers for a foreign-owned single-member LLC and what changes for a partnership or a corporation.

Lines 1 to 7: who the company is

Form SS-4, lines 1 to 7
LineAsksAnswer
1Legal name of entityExactly as the state approved it, including the suffix. Not a trade name
2Trade name, if differentBlank, unless you've registered a trade name
3Executor, administrator, trustee, care-of nameBlank
4a to 4bMailing addressWhere the IRS should send letters. An address abroad works, with the city, postal code and the country written in full, not abbreviated
5a to 5bStreet address, if differentThe company's physical address, only if it differs from the mailing address. Not a PO box
6County and state where the principal business is locatedThe company's primary physical location, which for a company run from your home abroad is where you are
7aName of responsible partyThe person who controls the company: the owner of a single-member LLC, a managing member of a partnership, or a principal officer of a corporation. Not the registered agent or a nominee
7bSSN, ITIN or EIN of the responsible party"Foreign" or N/A, if the responsible party has neither and can't get one. Never someone else's number

Lines 8 and 9: what kind of entity

Form SS-4, lines 8 and 9
LineAsksAnswer
8aIs this an LLC?Yes, for an LLC
8bNumber of LLC members1, or however many there are
8cWas the LLC organised in the United States?Yes
9aType of entityFor a single-member LLC owned from abroad: Other, with "Foreign-owned U.S. disregarded entity-Form 5472" written in. For a multi-member LLC: Partnership. For a corporation: Corporation, with the return it will file, Form 1120
9bState or country of incorporation, for a corporationWyoming or Delaware

Many guides tell a single-member LLC to write plain "disregarded entity" on line 9a. The IRS's instructions give that wording to an LLC that needs its EIN for payroll or a state requirement, and the longer one to an LLC that needs it to file Form 5472. Every single-member LLC with a foreign owner files Form 5472 each year, so the longer wording is the one that fits.

Line 9a sets what the IRS expects from the company every spring. A single-member LLC that ticks Corporation has told the IRS to expect a corporate tax return. It can be corrected, but that takes a letter and several weeks, so check the box before you send the form.

Lines 10 to 18: why, when and what

12Closing month of accounting yearDecember, for almost everyone
13Employees expected in the next 12 months0 in each box, unless you'll run US payroll

17Principal line of merchandise, product or serviceRequired, in plain words: subscription software, design services, imported homewares
18Has the entity applied for an EIN before?No. If it has, give the earlier number, and don't apply again without a reason

Third-party designee and signature

The designee section names someone the IRS can talk to about the application, which is how a filing agent follows it up. That authority only counts if the form is signed, and it ends once the EIN is assigned. The responsible party signs, with their title, such as Member, Managing Member or an officer's title.

Where to send it

These are the routes the IRS's December 2025 instructions give an applicant with no legal residence, principal place of business or office in the US. The IRS says the numbers can change without notice, so check them in the current instructions before you send anything.

  • Fax to 304-707-9471 from outside the US, or 855-215-1627 if you're faxing from inside it. Put a return fax number on the form so the IRS can fax the EIN back.
  • Phone 267-941-1099, Monday to Friday, 6am to 11pm Eastern time. It isn't toll-free. Whoever calls must be allowed to receive the EIN and answer questions about the form, so fill it in first and have it in front of you.
  • Post to Internal Revenue Service, Attn: EIN International Operation, Cincinnati, OH 45999. The IRS says the EIN arrives by post in about four weeks.

A company with a principal office in the US uses the domestic fax number instead.

After you send it

The IRS assigns the number and, if you gave a return fax number, faxes it back. The CP 575 confirmation is posted to the mailing address. The IRS says that under its Fax-TIN program an EIN by fax generally comes within 4 business days. For a company owned from abroad, our estimate is six to eight weeks. The phone route gives you the number the same day, if you can get through. The EIN guide covers the routes and timing.
