Common EIN Application Mistakes Foreign Founders Make

An EIN is a nine digit number the IRS gives your company. It works like a social security number, but for a business instead of a person. You need it to open a US bank account, sign up with payment processors like Stripe or PayPal, hire staff, and file your taxes.
If you don't live in the US, the process has a few extra steps that trip people up in specific, predictable ways. This guide walks through each one, with exact rules, exact form fields, and exact fixes.
The single biggest myth to clear up first:
“I don't have an SSN, so I can't get an EIN.”
That is false. You can get an EIN with no SSN, no ITIN, and no US address at all. The IRS has a specific process for exactly this situation. Most delays happen because founders don't know that process exists and try to force their way through the wrong one instead.
1. Applying for an EIN Before Your LLC Is Formed
Your business needs to legally exist before it can have a tax ID. The order has to be:
• File your LLC or corporation paperwork with the state.
• Wait for the state to approve it and issue your formation certificate.
• Apply for your EIN using the exact legal name and formation date on that certificate.
If you apply for an EIN before the state has approved your company, one of two things usually happens. The IRS rejects the application outright, or it issues an EIN tied to a company name or date that doesn't match your final, approved paperwork. Fixing a mismatch after the fact means writing to the IRS and explaining the discrepancy, which can take several weeks.
State approval timelines vary a lot. Wyoming and Delaware often approve LLCs within one to three business days if you file online. States like California or New York can take one to three weeks for standard processing, longer during peak filing months like December and January.
Once your company is approved, apply for the EIN before you book your bank appointment or sign up for a payment processor. Both of those steps usually ask for your EIN on the first form.
2. Assuming Foreign Founders Cannot Apply Online
The IRS online EIN system checks two things. If both are true, you can use it. If either is false, the system will not let you finish the application, no matter how many times you try.
• Your company has a legal residence, principal place of business, or principal office located inside the United States.
• The responsible party already holds a valid SSN, ITIN, or EIN.
A founder living in India, the UK, or the UAE, running the business entirely from outside the US, with no SSN or ITIN, will fail both conditions. That's why the online portal doesn't work for most foreign founders. It isn't a nationality check. It's a system requirement built around US residency and an existing US tax number.
The online tool itself is only open on weekdays, 7:00 a.m. to 10:00 p.m. Eastern Time, and it times out after 15 minutes of inactivity, so even eligible applicants sometimes have to restart.
If you don't meet both conditions, you skip the online tool entirely and go straight to the phone, fax, or mail process described in section 9. There is no workaround, and no formation service can make you eligible for the online system if you don't meet the two conditions above.
You can check the current rules yourself on the IRS EIN application page.
3. Entering the Wrong Responsible Party
The responsible party is the specific person the IRS holds a company accountable through. The IRS defines this as the individual who has a level of control over, or entitlement to, the funds or assets of the business that, in practice, lets them direct it, manage it, and dispose of its funds and assets. It has to be a real person, never a company, and never a nominee.
• If you own the LLC yourself, you are the responsible party.
• If a manager runs daily operations but you own the company, you are still the responsible party, not the manager.
• A registered agent should not be listed here. Their only job is to receive legal mail on behalf of your company in the state where it's formed. They have no control over the business.
A frequent mistake is letting the lawyer, accountant, or formation service handling your paperwork list themselves as the responsible party because they are the ones typing the form. The IRS specifically warns against this and calls it a nominee arrangement. A nominee is someone named on the application who does not actually own or control the company.
The IRS's own guidance on this is direct: it states that “a nominee is not a proper responsible party”, and that using one can create confusion about who the IRS should actually be contacting about the business.
The practical risk shows up later, not immediately. Banks cross check the responsible party name against your ownership documents when you open an account. If the names don't match, account opening gets delayed while you explain the discrepancy. It can also cause friction if your company is later reviewed, or when you file Beneficial Ownership Information with FinCEN, since that filing asks for the same kind of ownership and control details.
4. Thinking You Need an ITIN Before Getting an EIN
These are two different numbers for two different things, and mixing them up costs founders real time.
• EIN: identifies your company. Required to open a bank account, pay taxes as a business, and hire staff.
• ITIN: identifies you personally, if you don't qualify for an SSN. Used mainly for filing your own individual US tax return.
You do not need an ITIN to get an EIN. The EIN application has a specific path for applicants with no SSN or ITIN at all, covered in section 8 below.
An ITIN application (Form W-7) currently takes 7 to 11 weeks to process according to the IRS, longer during tax season. Founders who wait for an ITIN before applying for their EIN lose two to three months for no reason, since the ITIN was never a requirement to begin with.
Get your EIN first, using the foreign applicant process. Apply for an ITIN later, only if and when you personally need to file a US tax return, such as Form 1040-NR.
5. Putting the Wrong Information on Form SS-4
Form SS-4 is the actual EIN application. It has 18 numbered fields, and a handful of them cause almost all the rejections and delays we see.
• Line 1, legal name: must match your state formation certificate exactly, including “LLC” versus “L.L.C.” and any commas.
• Line 2, trade name: leave this blank unless you operate publicly under a different name than your legal one.
• Line 8a to 8c, entity type: select the box that matches your actual filed structure. LLC, corporation, and partnership are taxed differently, and this field drives that.
• Line 8b, number of LLC members: this single number changes your default federal tax treatment, explained fully in section 6.
• Line 7a and 7b, responsible party and their SSN, ITIN, or EIN: covered in sections 3 and 8.
• Lines 4a to 6, mailing and business addresses: use the correct address type, covered in section 7.
• Line 10, reason for applying: choose “Started new business” unless a more specific reason genuinely applies, such as banking purposes only.
Print the form, or fill it out digitally, then read it back against your state certificate line by line before you submit it by phone, fax, or mail. A single character mismatch in the legal name is the single most common reason an application gets sent back.
6. Selecting the Wrong Entity Classification
Your state paperwork says you formed an LLC. That tells you your legal structure. It does not automatically tell the IRS how to tax you, because the IRS applies its own default rules based on how many owners the LLC has.
• One owner: by default, the IRS treats this as a disregarded entity. The business's income and expenses are reported on the owner's own tax return, not a separate business return.
• Two or more owners: by default, the IRS treats this as a partnership, which files its own information return, Form 1065.
• You can also elect to have your LLC taxed as a corporation, using Form 8832 or Form 2553, but this is a separate, optional election, not the default.
Picking the wrong classification on Form SS-4 doesn't just create a paperwork mismatch. It sets your company's federal tax treatment until you actively file the paperwork to change it, which usually means an accountant sorting out which return type actually applies for the periods already filed.
If you have two or three founders, double check line 8b. A common error is entering “1” out of habit when the LLC actually has multiple members, which pushes the IRS to assume a single-owner structure that doesn't match reality.
7. Entering a US Address When You Don't Actually Have One
Form SS-4 has separate fields for different kinds of addresses, and each one plays a specific role.
• Line 4a, mailing address: where you want IRS letters sent. This can be your home address abroad, a virtual mailbox, or your accountant's address.
• Line 5a, street address (if different): your actual principal place of business, if it's different from your mailing address.
• Registered agent address: this belongs on your state formation paperwork, not on Form SS-4. It exists so your state has somewhere to send legal notices. It is not your business address.
A founder based in Mumbai or Dubai does not need to invent a US address to complete this form. Entering your real foreign address on line 4a is correct and expected. What causes problems is entering your registered agent's US address as if it were your actual business location, since that address then shows up on IRS records as your principal place of business when it isn't.
If you later open a US bank account or virtual mailbox, you can update your mailing address with the IRS at that point using Form 8822-B, covered in the correction section below.
8. Making a Mistake on Line 7b When You Don't Have an SSN or ITIN
Line 7b asks for the responsible party's SSN, ITIN, or EIN. This is the field that causes the most hesitation for founders with no US tax history.
The current IRS instructions for Form SS-4 state directly: if the responsible party does not have and is not eligible to obtain an SSN or ITIN, write “Foreign” on line 7b.
Do not leave the field blank. Do not write a made up number. Do not use someone else's SSN or ITIN, even a business partner's or a family member's, just to have something to type in the box. Any of these will either get the application bounced back or, worse, tie your company to the wrong individual's tax record.
Writing “Foreign” is a completely normal, IRS recognized entry. It routes your application through the international applicant process rather than the domestic one, which is exactly where it needs to go.
9. Using the Wrong EIN Application Method
There are four ways to apply for an EIN, and each one fits a different situation. Picking the wrong one for your circumstances is where most of the actual time gets lost.
Method | Typical use case | Key thing to know |
Online | Applicants who meet both eligibility conditions above | Instant EIN, but strict requirements |
Phone | International applicants with no US address or tax number | Same day EIN, IRS call only |
Fax | International applicants | About 4 business days |
International applicants | 4 to 5 weeks, sometimes longer |
If you don't meet both online eligibility conditions, the phone route is almost always your fastest option. Foreign applicants call the IRS directly at +1 267 941 1099 (this is not a toll free number), Monday to Friday, 6:00 a.m. to 11:00 p.m. Eastern Time. Fax and mail exist as backups mainly for founders who cannot make an international call during those hours.
10. Not Preparing Before Calling the IRS
The phone call to get your EIN as a foreign founder usually takes 20 to 45 minutes, and almost all of that time is the IRS agent reading Form SS-4 questions to you out loud, one field at a time. If you have the form filled out and in front of you before you dial, the call moves fast. If you don't, you'll be put on hold while you look things up, or asked to call back.
Have these ready before you dial:
• A completed Form SS-4, filled out exactly as you intend to submit it.
• The responsible party's full legal name, date of birth, and country of citizenship.
• Your company's exact legal name and formation date, taken directly from your state certificate.
• Your mailing address and, if different, your principal business address.
• A clear answer on entity type and number of members, since this is one of the first questions asked.
• A pen and paper, or a document open, to write down your EIN the moment it's given to you.
The agent will ask you to confirm each field on the form, then assign your EIN verbally before the call ends. Write it down immediately and repeat it back to the agent to confirm you heard it correctly. You will also receive a confirmation letter,
Form CP 575, by mail some weeks later, but the number itself is valid to use from the moment it's given to you on the call.
11. Submitting Multiple EIN Applications
Founders sometimes submit a second application because the first one hasn't come back yet, assuming it must have failed. This creates a real problem rather than solving one.
• A second application filed while the first is still active can result in two EINs for one company, which then confuses your bank and the IRS about which number is correct.
• The IRS limits each responsible party to one EIN per day, across every application method combined, online, phone, fax, and mail.
• If you're forming two or three companies in the same week under your own name as responsible party, you can only get one EIN issued per day. Plan which company applies on which day in advance.
If you've applied and haven't heard back within the expected window for your method, call the IRS Business and Specialty Tax Line to check your application status before filing again.
12. Ignoring Foreign Applicant Processing Delays
Each application method has a different real world turnaround time, and lining up your next steps against the wrong one causes avoidable delays.
• Online, if eligible: EIN issued instantly, confirmation letter (CP 575) mailed within a few weeks.
• Phone, international applicants: EIN issued verbally on the call, same confirmation letter mailed afterward.
• Fax: typically about 4 business days if you include a return fax number, otherwise you'll need to call in to get the number.
• Mail: 4 to 5 weeks under normal conditions, longer from January through April.
Don't schedule your bank appointment or start a Stripe or Wise application the same week you mail your SS-4 form. Match your booking to the method you actually used. If you applied by mail and the 5 week mark has passed with nothing back, call the IRS directly rather than mailing a second copy.
13. Assuming an EIN Means You're Tax Compliant
An EIN is an identification number. It does not, by itself, satisfy any filing requirement. For a foreign owned single member LLC in particular, the EIN is usually just the first of several obligations.
• Form 5472, filed together with a pro forma Form 1120, is required for foreign owned disregarded entities that had reportable transactions with their foreign owner during the year, such as capital contributions or owner loans. This is due by April 15, with an automatic extension to October 15 if Form 7004 is filed.
• Federal income tax filing obligations depend on whether the business is treated as engaged in a US trade or business, which is a separate legal test from simply having a US LLC.
• Some states charge an annual franchise tax or a flat annual fee regardless of income, for example Delaware's annual franchise tax and California's minimum franchise tax.
• Beneficial Ownership Information reporting with FinCEN may apply, depending on current enforcement status, and should be checked separately from your EIN paperwork.
The penalty for missing or filing an incomplete Form 5472 starts at $25,000 per form, which is why this specific requirement catches so many foreign owned LLCs off guard. Getting your EIN is step one. Confirm your actual filing obligations with an accountant familiar with foreign owned US entities before your first tax deadline arrives.
14. Creating Inconsistencies Between the EIN Application and Other Filings
The same company details end up on several separate documents, filed at different times, sometimes by different people. A small mismatch between them rarely causes a problem on its own, but it compounds.
Check these against each other before you file anything new:
• Your state formation certificate
• Your Form SS-4 EIN application
• Your operating agreement
• Your bank account application
• Your Beneficial Ownership Information report with FinCEN, if it applies to you
• Your tax filings, including Form 5472 if required
A responsible party listed as “Rahul Sharma” on your SS-4 and “R. Sharma” on your BOI report is the kind of mismatch that looks trivial until a bank compliance officer or an IRS letter asks you to explain it. Use one name format, spelled exactly the same way, across every one of these documents from the start.
15. Forgetting to Keep the EIN Confirmation
Your EIN confirmation letter, Form CP 575, is the official IRS document showing your EIN, your company's legal name, and the date it was assigned. Save the original PDF or scan the moment you receive it.
• Banks require it, or an acceptable substitute like Letter 147C, before they will open a business account.
• Stripe, PayPal, and most payment processors ask for it directly during merchant account setup.
• Your accountant will need it every year at tax time to confirm your EIN and legal name match IRS records.
If you lose it, you can't get a duplicate CP 575. Instead, call the IRS Business and Specialty Tax Line at 800 829 4933 (US callers) and request Letter 147C, which serves the same purpose and is accepted everywhere a CP 575 would be.
What to Do If You Made a Mistake on Your EIN Application
Each type of error has a specific, official fix. None of them require starting over.
I entered the wrong business name
Write to the IRS at the address on your CP 575 confirmation letter, on company letterhead if possible, stating the correct legal name and enclosing a copy of your state formation certificate showing that name. There is no dedicated form for this specific correction, so the letter itself is the official record.
I listed the wrong responsible party
File Form 8822-B within 60 days of the change. This is the IRS's dedicated form for updating the responsible party on file for an EIN, and it must be signed by an authorized person for the business, not the outgoing responsible party.
I entered the wrong address
Also use Form 8822-B for this. It covers both business address changes and responsible party changes on a single form, so you can update both at once if needed.
I selected the wrong entity classification
This is fixed through a formal election, not a letter. A single member LLC that wants to be taxed as a corporation instead of a disregarded entity files Form 8832. A domestic LLC or corporation electing S corporation treatment files Form 2553. Both have specific deadlines tied to your tax year, so involve an accountant before filing either one, since the effective date rules are strict.
I already received an EIN, should I apply again?
No. One legal entity keeps one EIN for its entire life, even if you change its name, address, or responsible party. Filing a second application creates a duplicate EIN, which then forces you to contact the IRS to have one of the two officially deactivated. Correct the specific field instead, using the steps above.

Frequently Asked Questions
Can a foreign founder get a US EIN without an SSN?
Yes. Write “Foreign” on line 7b of Form SS-4 if you don't have and can't get an SSN or ITIN, then apply by phone, fax, or mail. This is a standard, IRS recognized path, not a workaround.
Can a nonresident apply for an EIN online?
Only if your business has a US legal residence, principal place of business, or principal office, and the responsible party already holds an SSN, ITIN, or EIN. Most first time foreign founders fail the second condition and need to apply by phone instead.
Does a foreign-owned LLC need an EIN?
Yes, in practice every US LLC needs one, even a single member LLC with no employees. Banks and payment processors require it to open an account, and it's needed for Form 5472 filing if the LLC is foreign owned.
Do I need an ITIN before applying for an EIN?
No. These are separate numbers for separate purposes. Get your EIN first through the foreign applicant process. Apply for an ITIN later, only when you personally need to file a US individual tax return.
Who should be the responsible party on Form SS-4?
The individual who actually owns or controls the company, meaning they can direct its funds and decisions. This is the founder or majority owner, never a registered agent, lawyer, or formation service filing the paperwork on their behalf.
Can my registered agent apply for my EIN?
They can dial the call or send the fax for you, but their name should not go on line 7a as the responsible party unless they genuinely own or control the company, which a registered agent does not.
How long does it take to get an EIN as a foreign founder?
By phone, the same call, usually 20 to 45 minutes total. By fax, about 4 business days. By mail, 4 to 5 weeks, longer from January through April.
What happens if my EIN application is rejected?
Check the legal name against your state certificate, confirm the entity type and responsible party fields, and re-submit. Most rejections trace back to a name mismatch or a blank required field, not to ineligibility.
Can I apply for multiple EINs?
Each company needs its own EIN, but the IRS issues only one EIN per responsible party per day, across every method combined. If you're forming several companies in one week, spread the applications across different days.
Can I correct a mistake after receiving my EIN?
Yes. Use Form 8822-B for a responsible party or address change. Use a written letter with your formation certificate for a name correction. Use Form 8832 or 2553 for a classification change. See the correction section above for the specific steps.
Does getting an EIN make my foreign-owned LLC tax compliant?
No. A foreign owned single member LLC with any reportable transaction, such as a capital contribution from the owner, must still file Form 5472 with a pro forma Form 1120 by April 15, with penalties starting at $25,000 for missing it. The EIN is the starting point, not the finish line.
