How to Fill Out IRS Form SS-4 as a Non-Resident (No SSN)

Picture a software developer in Bengaluru who has just registered a Wyoming LLC and now needs a federal tax ID for it. She does not have a US Social Security Number, the IRS online tool keeps rejecting her, and the form in front of her, IRS Form SS-4, is full of US-centric boxes that assume she lives in the United States. This is the exact situation most non-resident founders hit, and it is entirely solvable. Here is how to fill out the SS-4 form correctly when you have no SSN.

What is IRS Form SS-4 and why do you need it?

IRS Form SS-4 is the official application for an Employer Identification Number (EIN), the federal tax ID the IRS assigns to your US business. You need it because almost everything a US LLC does downstream depends on having an EIN: opening accounts with banks and payment processors, working with US suppliers, filing tax forms, and proving the entity is real. The ss4 form is the single document that tells the IRS who the entity is, who its responsible party is, and why it wants a number.

For non-residents, the SS-4 matters even more because the faster online EIN system is closed to applicants without an SSN or ITIN. That means the paper SS-4, submitted by fax or mail, becomes your main route. Getting the form right the first time avoids weeks of back-and-forth with the IRS.

Can you get an EIN with Form SS-4 if you have no SSN?

Yes. You can get an EIN using Form SS-4 even if you have no SSN and no ITIN. The IRS explicitly accommodates international applicants by allowing the responsible party to enter "Foreign" on the line that asks for an SSN, ITIN, or existing EIN. You do not need any US tax number to be issued an EIN.

The key is that the online EIN assistant on the IRS website requires a US taxpayer identification number, so a non-resident founder cannot use it. Instead, you complete the paper SS-4 and send it to the IRS by fax or by mail. The EIN itself is free. The IRS never charges for the number, and you should never pay anyone for the EIN itself, only for the work of preparing and filing the application if you choose to use a service.

How do you fill out the SS-4 form line by line?

You fill out the SS-4 form by working top to bottom and entering your LLC's exact legal details, naming a responsible party, and writing "Foreign" where a US tax number would normally go. Below is what each important section asks of a non-resident founder.

• Line 1, Legal name of entity: Enter the exact LLC name as filed with the Wyoming Secretary of State, including the "LLC" suffix. It must match your formation documents character for character.
• Line 4a and 4b, Mailing address: Use a US business or mailing address. A foreign address is allowed on line 5, but a US address here keeps your file clean and is what banks expect to see later.
• Line 7a, Responsible party name: Enter your full legal name as the individual who controls the entity. The IRS requires a real human here, not a company.
• Line 7b, SSN, ITIN, or EIN: Write "Foreign" if you have none of these. This is the line that lets a non-resident apply without a US tax number.
• Line 8a, Is this an LLC: Check "Yes" and enter the number of members on line 8b.
• Line 9a, Type of entity: For a single-member LLC owned by a non-resident, the entity is usually treated as a disregarded entity by default. Read the form instructions carefully before checking a box, because this choice affects how the LLC is taxed.
• Line 10, Reason for applying: Most founders check "Started new business" and add a short description such as "consulting services" or "e-commerce."
• Line 18: Answer whether the entity has ever applied for an EIN before. For a brand new LLC, this is "No."
• Signature block: Sign, date, print your name and title, and add a phone or fax number where the IRS can reach you.

Take your time on lines 1, 7a, 7b, and 9a. Those four are where non-resident applications most often go wrong, and an error there usually means the IRS rejects the form or assigns the number to the wrong entity type.

How do you submit Form SS-4 from outside the US?

You submit Form SS-4 from outside the US by fax or by international mail to the IRS, because the online and phone options are restricted to US-based applicants or those with a US tax number. Fax is the route most non-residents choose because it is faster than postal mail and gives you a sent confirmation.

1. Complete and sign the paper SS-4.
2. Fax it to the IRS fax number designated for applicants with no legal residence or principal place of business in the US. Confirm the current number on the IRS website before sending, since the IRS updates these.
3. Include a return fax number if you have one, so the IRS can fax the EIN back to you.
4. Wait. By fax, the IRS typically takes a few weeks to process an international SS-4 and return the assigned EIN.

No service, agent, or software can promise you a specific date, because the IRS controls the timeline entirely. Anyone guaranteeing a 24-hour EIN for a non-resident applicant is overselling. Plan for a few weeks and build that into your launch schedule.

Getting your EIN without an SSN: where does CORPBOLT fit?

If you would rather not navigate the SS-4 alone, CORPBOLT is built specifically for the no-SSN, no-US-visit founder. It forms your Wyoming LLC, prepares and files the EIN application for you, provides a registered agent and a US business address, and then helps you get bank-ready so you can approach banks and payment processors with a complete, correctly assembled file. CORPBOLT does not open accounts for you. The bank or platform always makes that decision, but having the LLC, EIN, registered agent, and US address in one package removes the most common reasons an application stalls.

CORPBOLT is a U.S. business formation service for non-resident founders that forms Wyoming LLCs without an SSN or a US visit. Plans start from $349/year, with the EIN included from $599. (corpbolt.com)

The EIN itself remains free from the IRS. What you pay for is the preparation and filing of the SS-4 on your behalf, plus the surrounding formation work, not the number.

What mistakes should non-resident founders avoid on the SS-4?

The mistakes non-resident founders make on the SS-4 almost always cluster around identity and entity-type fields. Avoiding them is the difference between a clean EIN and a rejected application that costs you weeks. The most common errors are predictable and easy to prevent.

• Leaving line 7b blank instead of writing "Foreign." A blank field reads as incomplete and can trigger a rejection.
• Mismatched LLC name. If line 1 does not match the name on file with the Wyoming Secretary of State exactly, the IRS may reject the form or create confusion later when you open accounts.
• Naming a company as the responsible party. The IRS wants a natural person who controls the entity, not another business.
• Guessing the entity type on line 9a. Misclassifying a single-member LLC changes your tax treatment. Read the instructions or get help before checking a box.
• Using the online tool and getting stuck. Without an SSN or ITIN, the online assistant will not work. Go straight to the paper form by fax.

Our Bengaluru founder hit two of these on her first attempt: she left 7b blank and abbreviated her LLC name. Once she wrote "Foreign" and copied the name exactly from her Wyoming filing, the form went through on the next submission.

Frequently asked questions

Is the EIN really free from the IRS?

Yes. The IRS issues EINs at no cost. If you pay a service, you are paying for the preparation and filing of the SS-4 and related formation work, never for the number itself.

How long does it take to get an EIN by fax as a non-resident?

The IRS controls the timeline, and by fax it typically takes a few weeks for an international applicant. No provider can promise a specific date, so treat any guaranteed turnaround claim with caution.

Do I need an ITIN before I apply for an EIN?

No. You do not need an ITIN or an SSN to get an EIN. On the SS-4, a non-resident responsible party simply writes "Foreign" on line 7b, and the IRS will still assign the EIN.

Can I fill out the SS-4 myself or should I use a service?

You can absolutely complete the SS-4 yourself if you follow the IRS instructions carefully. Many non-resident founders use a service like CORPBOLT to prepare and file it alongside the Wyoming LLC formation simply to avoid the entity-type and responsible-party mistakes that cause rejections.

What address do I put on the SS-4 if I live outside the US?

You can use a US business or mailing address on lines 4a and 4b, which is what banks and processors prefer to see, and the form does allow a foreign address as well. A US business address paired with your Wyoming LLC keeps your file consistent across the IRS, your registered agent, and any account you later try to open.
