EIN for foreign founders is a simple request with a few strict rules. You need an Employer Identification Number, the IRS tax ID for a business, before a US LLC or corporation can open most bank accounts, hire staff or file federal returns. If you run your company from India or any other country outside the US, you cannot use the IRS online tool, so you apply by phone, fax or mail with Form SS-4.
This guide is for non-US founders who have formed, or are about to form, a US company. By the end you will know what an EIN is, how to name the responsible party, which application route to use, how to complete the form and where the number gets used afterwards. It is general information, not professional advice, and rules change, so confirm current requirements on the IRS pages linked at the end.
Key Takeaways
- An EIN is a free federal tax ID that the IRS issues directly to businesses and other entities.
- EIN for foreign founders runs through phone, fax or mail when the principal place of business is outside the US.

What EIN for Foreign Founders Means
An Employer Identification Number, or EIN, is a nine digit federal tax ID that the Internal Revenue Service (IRS) assigns to a business or other entity. EIN for foreign founders means a non-US owner obtaining that number for a US LLC or corporation, usually without holding a US Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). The IRS issues it free of charge.
The IRS lists several groups that need an EIN: businesses with employees, businesses that owe employment or excise taxes, and entities such as partnerships, LLCs and corporations. It also says you can request one for banking or state tax purposes even where federal law does not strictly require it. In practice, nearly every US company run by a foreign founder ends up needing one, so EIN for foreign founders is a routine early task.
Who needs one and who does not
- A multi-member LLC taxed as a partnership needs an EIN.
- A corporation needs an EIN, including a C corporation owned by a foreign parent.
- A single-member LLC often needs one for banking, payment platforms and federal reporting, even without employees.
- A company that plans to hire US staff or pay contractors needs one for payroll and information returns.
The IRS page on new EINs adds that a single-member LLC can use its own number when it does not elect corporation status and has no employees or excise tax duties. For a foreign-owned company, a separate EIN also keeps business and personal records apart.
An SSN or ITIN identifies a person, while an EIN identifies an entity. Our service page on US EIN registration covers the filing side.
Step 1: Form the Entity With the State First
The first step in getting an EIN for a US LLC is to create the entity at state level. The IRS online application page warns that applying before forming a corporation or LLC with your state may delay your EIN. The same logic applies to the paper route: the form asks for details that only exist once the state has accepted your filing.
Before you start, gather the following from the state filing:
- The exact legal name, including suffixes such as LLC, Inc. or Corp.
- The state of formation and the date it was formed.
- The business address and mailing address.
- The entity type, and for an LLC, the number of members.
Many founders choose Delaware or Wyoming, but the right state depends on where you operate. Our guide on a US LLC for non-US founders compares the choices and walks through registered agents, operating agreements and state filings. If you want the company set up for you, see our US LLC formation and US corporation formation services.
Why the legal name matters
The Form SS-4 instructions say to enter the name exactly as it appears on the charter or other legal document, and for a corporation to include any suffix. In the filings we handle, the most common delay is a mismatch between the name on the application and the name on the formation documents, so we compare them side by side before anything is submitted.
Step 2: Identify the Responsible Party
For EIN for foreign founders, the responsible party is the person who owns, controls or effectively controls the entity and handles its money and assets, directly or through others. The IRS states that the responsible party must be a person, not an entity, with an exception for government entities. This is the EIN responsible party requirement, and it trips up founders who hold the US company through another company.
The IRS lists typical responsible parties by entity type:
- Corporation: the principal officer.
- Partnership: a general partner.
- Trust: the grantor, owner or trustor.
- Estate: the executor, administrator or personal representative.
For an LLC owned by a foreign company, you still need to name the individual who ultimately owns or controls the entity. The IRS adds that someone who can fund an entity, or is entitled to its property, is not automatically a responsible party if they cannot control, manage or direct it.
Nominees cannot apply
A nominee is someone with limited authority during formation and little or no control over the assets. The IRS says nominees cannot apply for an EIN and should not appear on Form SS-4. If a formation agent filed your state paperwork, identify the real responsible party before the EIN application, not after.
If the responsible party changes, report it within 60 days using Form 8822-B.
Step 3: Choose Your Application Route
The route for EIN for foreign founders depends on where the principal place of business sits. The IRS online EIN application is limited to entities formed in the US or a US territory with a US principal place of business, and the responsible party must have an SSN or ITIN. If your principal place of business is outside the US, the IRS says you can call, fax or mail instead.
The core of EIN for foreign founders is three offline routes, each with different trade-offs.
Phone Route for EIN for Foreign Founders
The IRS lists 267-941-1099 for international applicants, Monday to Friday, 6 a.m. to 11 p.m. Eastern time. The number is not toll-free. An IRS representative takes the details and assigns the EIN during the call, so have a completed Form SS-4 in front of you.
Fax Route for EIN for Foreign Founders
You fax the signed Form SS-4 to 855-215-1627 from within the US, or 304-707-9471 from outside the US. Include a fax number so the IRS can send the EIN back. The IRS pages we reviewed say the EIN generally comes back within 4 business days on this route.
Mail Route for EIN for Foreign Founders
You post the form to the EIN International Operation in Cincinnati, OH 45999. The IRS says this takes about 4 weeks, and it advises applying at least 4 to 5 weeks before you need the number. Mail suits founders with no reliable fax or phone access.
A worked example
Consider a founder in Pune who has formed a single-member Delaware LLC. She has no SSN or ITIN and no US office. The online tool is closed to her, so she prepares Form SS-4, writes "foreign" on line 7b, signs it and either phones the IRS or faxes it with her own fax number. This is an illustration of EIN for foreign founders, not a client story, and the timing follows whatever the IRS states at the time.
Step 4: Complete Form SS-4 Accurately
Form SS-4 is the IRS Application for Employer Identification Number. Form SS-4 for foreign applicants follows the same layout as the domestic version, but a few lines need extra care. The IRS instructions provide line by line guidance, and we keep a printed copy open while preparing every application.
| Line | What to enter | Foreign founder note |
|---|---|---|
| 1 | Legal name as on state record | Include LLC, Inc. or Corp. |
| 7b | Responsible party taxpayer ID | "Foreign" or N/A if no SSN or ITIN |
| 8a, 8b | LLC status and member count | One member is disregarded |
| 9a | Entity type | "Other", write "disregarded entity" |
| 16, 17 | Activity and description | Be specific and consistent |
Line 7b: EIN without SSN or ITIN
The instructions say that if the responsible party does not have an SSN or ITIN and cannot get one, you enter "foreign" or N/A, and an entry is required. This is the line that makes an EIN without SSN or ITIN workable. Leaving it blank is a common reason for delay.
LLC member count and entity type
The IRS instructions state that a domestic LLC with one member is disregarded by default, and a domestic LLC with two or more members is a partnership by default. For a single-member disregarded entity, you check "Other" on line 9a and write "disregarded entity." If you want corporate tax treatment, a separate election applies, and the IRS notes that an entity classification election on Form 8832 requires the entity to have an EIN.
Principal activity and signature
Line 16 asks for one box that best describes the principal activity, and line 17 asks for a more detailed description. Pick a description that matches your website, your bank application and your later tax returns. The signature must come from a person with authority. The IRS says foreign applicants may have any duly authorized person, such as a division manager, sign.
Step 5: Submit and Save the Confirmation
Once the form is complete, submit your EIN for foreign founders application by your chosen route and keep the proof. The IRS says you can apply for only one EIN per day, whether online or by phone, mail or fax, so do not send duplicate applications while you wait. A second submission for the same entity creates confusion rather than speed, and it is a frequent slip in EIN for foreign founders cases.
When the number arrives, save the written confirmation. The IRS says the original CP 575 notice, which confirms an EIN, cannot be duplicated, but a digital CP 575 is available through the Business Tax Account and can substitute for the older notice series and Letter 147C. Banks and other institutions accept it as written confirmation of an entity's EIN, and the IRS advises keeping it in permanent records and making several copies.
When EIN for Foreign Founders Can Start Using the Number
The IRS says you can use the EIN immediately for most needs, such as opening a bank account, applying for licenses or filing a return by mail. It also says to wait up to 2 weeks before passing a TIN Matching Program check, e-filing or making electronic tax deposits. Plan your payroll schedule and electronic payments around that gap.
A Simple Walkthrough for EIN for Foreign Founders
- Confirm the state filing is complete and note the exact legal name.
- Decide who the responsible party is and whether they have an SSN or ITIN.
- Pick phone, fax or mail based on your deadline and access.
- Complete Form SS-4 and check every line against the formation documents.
- Submit, then record the date, the route and who handled it.
- File the EIN confirmation with your company records.
Step 6: Use the EIN for Banking and Tax Filings
An EIN is the business's tax identity, and EIN for foreign founders connects to several later tasks. Knowing these in advance helps you avoid a rushed scramble after the number arrives. This step is where EIN for foreign founders turns from paperwork into daily operations.
Banking and payment platforms
For EIN for foreign founders, many US banks, payment processors and marketplaces ask for the EIN confirmation, the formation documents and identity details for the owner. The IRS says an EIN can be requested for banking even where federal law does not require one. Opening an account can take longer for a non-US owner and policies vary by provider, so confirm what each one needs before you apply.
Federal Tax Filings After the EIN
The EIN identifies the company on its federal returns. A foreign-owned single-member LLC that is a disregarded entity has a special rule: the IRS instructions say it must file a pro forma Form 1120 with Form 5472 attached by the Form 1120 due date, including extensions. The instructions also state a $25,000 penalty for a reporting corporation that fails to file Form 5472 on time and in the required manner, and note that these filers cannot e-file the form. Our guide on a US LLC for non-US founders explains the filing in more detail.
Payroll, state registrations and sales tax
If you hire US employees, the EIN is used to run payroll and report employment taxes. State tax accounts and licences also ask for it. If you sell goods or services that create sales tax obligations, the next step is often US sales tax registration. For ongoing returns, our US business tax filing service handles the federal and state work.
Application Routes at a Glance
The table below compares the routes available for EIN for foreign founders. It uses only what the IRS pages we reviewed state, and you should confirm the current numbers and times on the IRS site before you apply.
| Route | Who can use it | What the IRS states |
|---|---|---|
| Online | US entities with a US principal place of business and an SSN or ITIN | EIN issued immediately |
| Phone | International applicants | 267-941-1099, Mon to Fri, 6 a.m. to 11 p.m. Eastern |
| Fax | Applicants with no US location | About 4 business days with a fax number |
| Any applicant | About 4 weeks to the EIN International Operation |
Common Mistakes to Avoid
Most failed EIN for foreign founders applications are not complex errors. They are small mismatches that cost days or weeks, especially on a route where corrections are slow. Based on the IRS guidance and the filings we handle, these are the mistakes worth checking for.
- Applying before the state accepts the filing. The IRS warns this may delay the EIN.
- Naming a nominee or a company as the responsible party. The IRS requires an individual who controls the entity, and nominees cannot apply.
- Leaving line 7b blank. Foreign founders with no SSN or ITIN enter "foreign" or N/A.
These form errors are just as common:
- Using a different legal name from the state record. Match suffixes and spelling exactly.
- Choosing the wrong entity type or member count. This changes the default tax treatment.
After submission, watch for these:
- Submitting twice. The IRS allows one EIN per day, and duplicates cause confusion.
- Not saving the confirmation. Banks ask for it, and the original notice cannot be duplicated.
- Forgetting Form 5472. A foreign-owned disregarded entity still has a filing duty, with a stated $25,000 penalty for missing it.
- Paying a website for the IRS number itself. The IRS says you never have to pay a fee for an EIN.
Summary
An EIN is the free federal tax ID that every US LLC or corporation needs for banking, payroll and federal filings. EIN for foreign founders, meaning an EIN for a US LLC or corporation owned abroad, runs through phone, fax or mail, because the online tool is limited to US applicants. Form SS-4 for foreign applicants needs the exact legal name, a correct entity type and a named individual as responsible party. An EIN without SSN or ITIN is possible by entering "foreign" or N/A on line 7b. After issue, save the confirmation and plan for Form 5472 if the LLC is foreign-owned.
Conclusion
EIN for foreign founders is manageable when you follow the order: form the entity, name the responsible party, pick the route, complete the form, submit and keep the confirmation. The IRS publishes the numbers and rules, and they can change, so confirm them before you apply.
