Foreign founder's complete guide to forming a US LLC without an SSN

Founders outside the United States are told this is hard, and the advice they get is usually wrong: that a visit is required, that an ITIN comes first, or that the whole thing must be routed through an offshore holding company. None of that is true. Only one step is genuinely awkward, the employer identification number, because the fast online channel is closed to anyone without a US taxpayer identification number. Everything else follows in order, and the order matters more than the speed.

Step 1: Choose the State

A founder with no US premises and no US employees has real freedom here, because no state has first claim. The practical shortlist is Wyoming, Delaware, New Mexico and Florida, and the deciding factors are annual cost and whether outside investment is likely.

Wyoming and New Mexico are the low-cost options and suit a solo founder invoicing customers from abroad. Delaware costs $400 a year to hold and is worth it only where institutional investment is genuinely on the horizon, a trade-off examined in the Delaware cost page. California is the frequent wrong answer, because its franchise tax applies whether or not the company earns anything there. The full comparison sits in the best state to form an LLC and how to choose a state.

That freedom ends the moment the company acquires a real US presence: staff, an office, inventory in a warehouse. It then generally has to register in that state too, which is the subject of when to foreign qualify.

Step 2: File the Formation Documents

Nothing here requires an SSN, US residence or citizenship. The articles of organization name the company, its registered agent and its address, and in some states its members or managers. The agent must have a physical street address in the state and be available in business hours, which is why a non-resident founder always uses a commercial provider; see what a registered agent does and acting as your own agent.

Prepare two documents no state demands. An operating agreement settles ownership and control, and for a sole owner it is what a bank asks for as proof of control; the operating agreement guide explains why a single-member company still needs one. The second is a clean set of members' identity documents, because every later step asks for them. Entity fundamentals are in what an LLC is and the single-member LLC guide.

Step 3: Get the EIN Without an SSN

The employer identification number is the federal number for the company. Without it there is no US bank account, no payment processor and no way to hand a completed W-8BEN-E or W-9 to a US customer who asks for one. It is issued free by the IRS on Form SS-4.

Why the online application is closed to you

The IRS instructions to Form SS-4 state that the principal officer, general partner, grantor or owner must have a valid taxpayer identification number, an SSN, EIN or ITIN, to use the online application, and that an applicant with no legal residence, principal place of business or office in the United States or its territories cannot use it at all. That is a channel restriction, not an eligibility one. The company is entitled to an EIN; it just has to be asked for another way.

Line 7b and the word foreign

Line 7b of Form SS-4 asks for the responsible party's SSN, ITIN or EIN, and a founder without any of them frequently leaves it blank, which is a common reason an application comes back. The instructions give the answer directly: enter foreign or N/A on line 7b if the responsible party does not have and is ineligible to obtain an SSN or ITIN. Complete the rest of the form fully, sign it, and be aware that EIN issuance is limited to one per responsible party per day.

The three channels that do work

Telephone. The IRS offers this option to international applicants only. If you have no legal residence, principal place of business or principal office or agency in the United States or its territories, you may call 267-941-1099, which the IRS notes is not a toll-free number, from 6:00 a.m. to 11:00 p.m. Eastern time, Monday through Friday. The person calling must be authorised to receive the EIN and to answer questions about Form SS-4, so fill the form in before dialling and read from it. This is the fastest route by a wide margin.

Fax. Under the Fax-TIN program the IRS says you generally receive the EIN by fax within four business days. An applicant with no legal residence, principal place of business or office in any state or the District of Columbia faxes to 855-215-1627 from inside the United States or 304-707-9471 from outside it. Provide a fax number so the IRS can send the number back.

Mail. The slowest. The IRS asks applicants to complete Form SS-4 four to five weeks before the EIN is needed and says the number arrives in roughly four weeks. Use it only if the others are unavailable. Detail on all three is in the EIN application guide; the six to eight week figure in older material describes mail, not fax.

Do You Need an ITIN as Well?

This is where sequencing advice most often goes wrong. An ITIN is a personal number for an individual who has a US federal tax obligation but cannot get a Social Security number. It is not required to form a company, and it is not required to obtain an EIN, which is precisely why line 7b has the word foreign on it. Most non-resident owners of a US LLC that has no US-source effectively connected income never need one.

It becomes necessary when a personal filing requirement appears: income reportable on a Form 1040-NR, a treaty benefit to claim, or a withholding position that needs a number. Form W-7 is normally filed with the return that creates the need. There are three routes: mail to the IRS service centre in Austin with original documents, an IRS Taxpayer Assistance Center which authenticates most documents and returns them immediately, or a Certifying Acceptance Agent who authenticates for a fee. Allow seven weeks for a decision, or nine to eleven between January 15 and April 30 or from overseas. ITINs expire and renew on the same form. Detail is in the Form W-7 guide.

Step 4: Open the US Bank Account

This is the step that used to defeat non-resident founders and is now the one most sensitive to preparation. Traditional branch banking generally expects an in-person visit, government photo identification, a US address and often a Social Security number for the signer, which for a founder who has no reason to travel makes it impractical. Online-first business banking platforms built for remote founders will open an account from abroad, and they ask for the same underlying evidence in a different order.

Whichever route you take the file is the same: file stamped articles from the state, the EIN confirmation, the operating agreement showing who controls the company, passports for every beneficial owner, proof of each owner's residential address, and a plain description of the business and its customers. Applications fail on inconsistency far more often than on nationality. A name spelled differently on the articles and the passport will hold a review up longer than living abroad ever does. Our business banking page covers the options.

Step 5: Form 5472 and the Pro Forma 1120

Here is the obligation that catches people, and it is federal rather than state. A US limited liability company with a single foreign owner is treated as a disregarded entity, and the IRS requires it to file a pro forma Form 1120 with Form 5472 attached, with the words foreign-owned U.S. DE written across the top of the 1120. It is due by the due date of that Form 1120, including extensions. Crucially it is owed even when the company had no income at all, because the form reports transactions between the company and its foreign owner, including the money used to form and fund it.

The submission route is unusual: the package is not e-filed with an ordinary return. The IRS accepts it by fax on 855-887-7737 or by mail to the service centre in Ogden, Utah. Alongside it sit the state obligations, which for Wyoming means a $60 annual report, for Florida $139, for Delaware the $400 annual tax with no report at all, and for New Mexico nothing recurring. The mechanics of the federal filing are set out in the Form 5472 guide and the tax framework in the LLC tax guide.

What Happens If You Miss Form 5472

The penalty is the largest number in this entire process and it is not scaled to the size of the business. The IRS assesses $25,000 on a reporting corporation that fails to file Form 5472 when due or fails to maintain the required records. If the failure continues for more than 90 days after the IRS notifies the company, a further $25,000 applies for each related party, for each 30-day period or part of a period during which the failure continues.

Read that second sentence carefully. A dormant single-member LLC formed with $2,000 of capital is exposed to $25,000 for one missed year, and $25,000 more for every 30 days after a notice is ignored. The filing itself is free. That gap is why this belongs in a calendar rather than in memory, and why anyone who has never filed one should read the catch-up section of the 5472 guide.

What the Whole Sequence Costs

State fees are the only unavoidable cash cost of the first year, and they are modest. Forming in Wyoming is $100 with a $60 annual report after that; New Mexico is $50 with nothing recurring; Florida is $125 with $139 a year; Delaware is $110 with $400 a year. The EIN is free from the IRS through any of the three channels above, and Form 5472 costs nothing to file. Add a registered agent, which is not optional for a non-resident, and a preparer for the annual federal package if you do not want to handle it yourself.

Set that against the alternative some founders are sold. An offshore holding company with its own registered office, service provider and annual return typically runs well into four figures a year and still does not solve the bank account on its own.

Three Founders in Practice

Scenario one: a designer in Lisbon forming in Wyoming

Salvea Studio LLC is formed in Wyoming for $100 by a product designer living in Lisbon with two US agency clients. She has no SSN and no ITIN. She completes Form SS-4, writes foreign on line 7b, and calls 267-941-1099 on a Tuesday afternoon Eastern time; the EIN is issued on the call. With the articles, the EIN letter and a one-page operating agreement she opens an online US business account. Her recurring obligations are a $60 Wyoming annual report and the Form 5472 package each year. She never applies for an ITIN, because she has no personal US filing requirement.

Scenario two: a ceramics brand in Sao Paulo forming in Delaware

Tidewater Ceramics LLC forms in Delaware for $110 because the founder expects to raise from a US fund within two years. He faxes Form SS-4 to 304-707-9471 from Brazil and has the EIN back in four business days. Delaware costs him $400 a year with no report to file, which he diaries for June 1 precisely because nothing will remind him. When a personal filing requirement later appears he applies for an ITIN on Form W-7 alongside that return, rather than obtaining one in advance for no reason.

Scenario three: a freight broker in Nairobi forming in Florida

Okapi Freight LLC forms in Florida for $125, where the annual report is $139 and the deadline is strict. The founder mails Form SS-4 rather than faxing it and waits four weeks, delaying the bank account and the first customer contract by a month: the channel choice at Step 3 sets the pace of Step 4. In year one the company still files Form 5472 with a pro forma Form 1120 reporting the capital contribution used to start the business, a reportable transaction even though it took no revenue for four months.

Five Mistakes Founders Without an SSN Make

Mistake 1: Applying for an ITIN first

What happens. A founder spends two months obtaining an ITIN before starting on the company. Why it fails. An ITIN is a personal number tied to a personal US tax obligation, and the EIN application has an explicit answer for applicants who have neither an SSN nor an ITIN. Consequence. Two months lost, and often an application refused for having no filing requirement to attach it to. Prevention. Form the company, get the EIN, and apply for an ITIN only when a return actually requires one.

Mistake 2: Leaving line 7b blank

What happens. Form SS-4 goes in with no entry for the responsible party's identification number. Why it fails. The instructions require the word foreign or N/A where the responsible party has neither and is ineligible for either. A blank reads as incomplete. Consequence. The application comes back, and with the one-per-responsible-party-per-day limit the retry is not instant. Prevention. Write foreign on line 7b.

Mistake 3: Using the mail channel by default

What happens. The founder posts Form SS-4 because that is what an article recommended. Why it fails. Mail takes roughly four weeks against four business days by fax and a single call by telephone. Consequence. A month of delay to the bank account and every contract that depends on it. Prevention. Call 267-941-1099 during its Monday to Friday hours, or fax.

Mistake 4: Forgetting Form 5472 in a year with no income

What happens. The company earns nothing, so nothing is filed. Why it fails. The obligation reports transactions with the foreign owner, and funding the company is such a transaction. A zero-revenue year is still a reportable year. Consequence. $25,000, plus $25,000 for each 30-day period once the failure runs past 90 days after notice. Prevention. Diary the Form 1120 due date from the first year the entity exists.

Mistake 5: Inconsistent identity details across documents

What happens. The name on the articles, the EIN record and the passport differ by a middle name or an accent. Why it fails. Bank onboarding and IRS records both match on exact strings, and a reviewer with a mismatch escalates rather than assumes. Consequence. Weeks of back and forth at exactly the point money needs to move. Prevention. Pick the passport spelling and use it on every document from the articles onward.

How File.Business Handles This

We file the articles in the state you choose, appoint the registered agent, prepare Form SS-4 with line 7b completed as the instructions require, obtain the EIN through the channel that suits your time zone, and hand over the bank-ready document set. Entities on our compliance plan get the state deadline and the Form 5472 date tracked together, and the annual report service covers every state we file in. If the entity exists and the federal filings were never made, say so at the start and we will scope the catch-up.

Go deeper: the EIN application guide for all three channels, the ITIN guide if a personal return is coming, and Form 5472 for the annual federal filing.
