How a Foreigner Gets a US Tax ID for a Business
A founder I traded notes with last year runs a small product studio from Dhaka, Bangladesh. She had already named her US company and lined up a payment processor, then froze on one line in the application: enter your business tax ID. She had no Social Security Number, no US address she could point to, and a dozen forum threads telling her ten different things. If you are a non-resident staring at that same blank field, here is the plain version of what a US business tax ID actually is and how a foreigner gets one.
What is the US tax ID a foreign business owner actually needs?
The US tax ID a foreign business owner needs for a company is an Employer Identification Number, the EIN, issued by the IRS. It is a nine-digit number formatted as 12-3456789 that identifies your business entity, the same way a Social Security Number identifies a person. When a bank, a payment processor, or a supplier asks for your company tax ID, they are asking for the EIN.
The confusion comes from three different identifiers that all get loosely called a tax ID number for foreigners, and they are not interchangeable. Keeping them straight saves you weeks.
- EIN (Employer Identification Number): the business tax ID. Issued by the IRS to your LLC or corporation. This is what opens business accounts, files business returns, and goes on contracts. A non-resident can get one without any SSN.
- SSN (Social Security Number): a personal tax ID for US citizens and certain work-authorized residents. Most non-resident founders will never have one, and you do not need one to get an EIN.
- ITIN (Individual Taxpayer Identification Number): a personal tax ID for individuals who owe US tax but cannot get an SSN. You apply for it on Form W-7. It is about you the person, not your company, and it is a separate process from the EIN.
For the question most foreign founders are really asking, which is how do I get the number my business needs, the answer is the EIN. The rest of this stays on that one form so you are not chasing the wrong thing.
Do you need an SSN or ITIN to get an EIN?
No. You do not need an SSN or an ITIN to get an EIN for your US business. The IRS issues EINs to companies whose owners are non-residents with no US tax number at all, and this is an ordinary, documented path, not a loophole.
Here is where the wires usually get crossed. The fast online EIN tool on the IRS website asks the responsible party for an SSN or ITIN, and if you do not have either, that tool will not work for you. That single dead end convinces a lot of founders they are stuck. They are not. The online tool is only one channel. The IRS has a separate, deliberate process for applicants without a US tax number, and it runs on a paper form.
The founder in Dhaka had spent an afternoon fighting the online tool before she realized it was never built for her situation. Once she switched to the right channel, the path was straightforward, just slower.
How does a non-resident file for an EIN without an SSN?
A non-resident files for an EIN without an SSN by submitting IRS Form SS-4 directly to the IRS, with the responsible party section completed using the foreign owner's name and a note that no SSN or ITIN exists. Because the online tool is closed to applicants without a US tax number, you send the SS-4 to the IRS by fax or by mail rather than entering it on the website.
The mechanics, step by step, look like this:
- Form the entity first. An EIN is issued to a business, so the company has to exist before the IRS will assign a number. For most non-resident founders that means a registered LLC, with its formation documents already filed and accepted by the state.
- Complete Form SS-4. List the legal entity name, the responsible party (you, the owner), the entity type, and the reason you are applying. Where the form expects an SSN or ITIN for the responsible party, a foreign applicant writes that none exists rather than leaving it blank.
- Submit it to the IRS. Fax is the channel most non-residents use because it moves faster than international mail. You can also call the IRS international line, but the written SS-4 by fax is the path most foreign founders rely on.
- Wait for the IRS to assign and return the number. The IRS controls the timing. By fax it typically takes a few weeks, and there is no way to pay for a guaranteed date. Anyone promising you a number "in 24 hours" is selling certainty that does not exist for paper SS-4 applications.
One detail that trips people up: the EIN itself is free. The IRS does not charge anyone, anywhere, for issuing an EIN. If you pay for help, you are paying for someone to prepare and file the application correctly and to chase it through the IRS, never for the number itself.
What is the responsible party, and can it be a non-resident?
The responsible party on Form SS-4 is the individual who ultimately controls or owns the entity, and yes, that person can be a non-resident with no US presence. The IRS wants a real human in that field, not another company. For a single-owner foreign LLC, the responsible party is simply you.
How can you get your EIN without an SSN in the simplest sequence?
The simplest sequence for getting an EIN without an SSN is to have your US company formed and the SS-4 prepared and filed for you in one motion, so the entity and the tax ID application are handled together instead of in two disconnected steps. That sequencing matters, because the EIN cannot be requested until the company legally exists, and a mistake on the SS-4 sends you back to the end of the IRS queue.
This is the lane CORPBOLT is built for. 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)
A few things to be precise about, because the category is full of overpromising. CORPBOLT prepares and files the EIN application; the number is still issued by the IRS, on the IRS's timeline, at no charge for the number itself. CORPBOLT is fully remote and built for non-resident founders, so there is no US visit and no SSN required. It bundles the pieces a foreign founder needs in one place: a Wyoming LLC, the EIN application, a registered agent, and a US business and mailing address. On banking, CORPBOLT helps you get bank-ready and prepare to open an account by getting your formation documents, EIN, and address in order. It does not open accounts or introduce you to a bank, and the bank or platform always makes the final decision. That is the honest boundary, and knowing it up front keeps your expectations where they belong.
Why do banks and processors ask for the EIN specifically?
Banks and payment processors ask for the EIN specifically because it is how they verify that your business is a registered US entity recognized by the IRS, separate from you as an individual. When you apply for a US business account or set up a processor like Stripe or PayPal, the EIN is the number that ties the application to a real, identifiable company.
This is also why getting the EIN early is worth the wait. Without it, almost every downstream step for a US business stalls: account applications, processor onboarding, and clean bookkeeping all key off that number. With it in hand, the rest of the foreign-founder setup tends to move in the order you would expect.
- The EIN proves the entity exists and is registered with the IRS.
- It separates business identity from personal identity, which matters more when the owner has no SSN.
- It is the reference number for filing the business's US tax obligations.
- It is requested by name on most US business banking and processor applications.
How long does it take a foreigner to get a US business tax ID?
For a foreigner filing Form SS-4 by fax, getting a US business tax ID typically takes a few weeks, and the IRS alone controls that timeline. There is no expedite fee that buys a faster EIN, and no provider can promise a delivery date, because the issuing is done entirely on the IRS's side.
What you can control is everything that happens before the IRS receives the form. A correctly completed SS-4, with the responsible party section handled properly for a non-resident, avoids the rejections and resubmissions that quietly add weeks. The founder in Dhaka did the boring part well, filed once, and then simply waited rather than refiling in a panic. Patience plus a clean application is the whole game once the form is in the IRS's hands.
Frequently asked questions
Is the EIN the same as a TIN?
A TIN, or Taxpayer Identification Number, is the umbrella term, and the EIN is one type of TIN. SSNs and ITINs are also TINs. When a US form asks for a business TIN, your EIN is the number that fits.
Can I get an EIN before my LLC is formed?
No. The IRS issues an EIN to an existing business entity, so the company must be legally formed and accepted by the state first. This is why forming the entity and preparing the EIN application in the right sequence saves time.
Does a non-resident need an ITIN as well as an EIN?
Not necessarily, and not for the company itself. The EIN is the business tax ID and stands on its own. An ITIN is a personal number you would apply for separately on Form W-7 only if your own situation creates a US tax filing obligation for you as an individual.
Do I have to pay the IRS for an EIN?
No. The EIN is free from the IRS. Any cost you incur is for preparing and filing the application correctly, especially the non-resident SS-4 path, never for the number, which the IRS issues at no charge.
Can I do all of this without visiting the United States?
Yes. A non-resident can form a US LLC and obtain an EIN entirely remotely, with no US visit and no SSN, because both the state filing and the SS-4 submission can be handled from abroad. The whole sequence is designed to work for founders who never set foot in the country.
