EIN and a US business bank account without an SSN: the non-resident's route

Running a US-based business from abroad is one of the most practical ways to access dollar-denominated revenue, US payment processors, and a customer base that expects an American entity on the invoice. The stumbling block for most non-resident founders is not forming the LLC itself: that part is relatively straightforward. The real friction hits at two later stages: getting a federal tax identification number and opening a bank account, both without a Social Security Number. These are solvable problems, but they require the right sequence of steps, the right documents, and honest expectations about timelines. This guide reflects the process as it stands in 2026, though rules and provider policies shift regularly, so confirm specifics before you act. If you are a non-resident founder or an adviser helping one, the approach below will save you weeks of guesswork and keep you on the right side of the IRS from day one.

The two things non-residents get stuck on

The first wall is the EIN, or Employer Identification Number. The IRS issues EINs to identify business entities for tax purposes, and every US LLC needs one before it can open a bank account, file returns, or receive payments through most processors. The online EIN application on the IRS website requires either an SSN or an ITIN, which immediately disqualifies anyone who has neither. Non-residents assume this means they cannot get an EIN at all, which is incorrect: there is a separate process for international applicants.

The second wall is banking. US banks are notoriously cautious about onboarding entities whose owners live overseas, lack a US address, and cannot walk into a branch. Many non-residents form their LLC, hit a dead end at the banking stage, and leave the entity dormant. The fix is knowing which types of accounts accept remote applications and what documentation each provider expects. Getting these two pieces right, in the correct order, is the entire puzzle.

Getting an EIN without an SSN

An EIN is not an SSN, and it does not require one. The IRS explicitly allows a foreign person with no SSN or ITIN to apply for an EIN by completing Form SS-4 and submitting it through one of three channels available to international applicants:

• Fax to the IRS's dedicated international fax line, with a response typically returned within four to seven business days.
• Mail to the IRS, which can take four to six weeks or longer.
• Phone call to the IRS's international line at +1-267-941-1099 (not a freephone number), available during US Eastern business hours. A live agent processes the application and can issue the EIN during the call itself.

The responsible party listed on Form SS-4 can be the foreign owner. You enter "Foreign" in the SSN/ITIN field, and the application proceeds. The phone method is the fastest, though hold times vary wildly: some founders report waits of ten minutes, others over an hour.

Cosmos coordinates this step for non-resident founders through its US formation partners, handling the SS-4 preparation and submission so you do not need to manage international call timing or fax logistics yourself. Whichever route you choose, the result is the same: a nine-digit EIN assigned to your LLC, which unlocks the banking stage.

ITIN: when you actually need one

There is persistent confusion between an EIN and an ITIN, and many non-residents apply for an ITIN unnecessarily. An ITIN, or Individual Taxpayer Identification Number, is obtained via Form W-7 and exists for one purpose: to allow individuals who are not eligible for an SSN to file a personal US tax return.

You need an ITIN only if you have effectively connected income that triggers a US personal filing obligation, typically via Form 1040-NR. Simply owning a US LLC or obtaining an EIN does not, by itself, require an ITIN. A single-member LLC owned by a non-resident with no effectively connected income still has annual filing obligations (more on that below), but those are entity-level filings tied to the EIN, not to an ITIN.

If your situation does require an ITIN, the application process involves submitting Form W-7 with a qualifying tax return and identity documents, either directly to the IRS or through a Certifying Acceptance Agent. Processing takes several weeks. The key point: do not delay your EIN or bank account waiting for an ITIN you may not need.

Opening a US business bank account as a non-resident

Once you have the LLC and the EIN, banking becomes the priority. A US business bank account lets you receive payments in dollars, pay US vendors, and separate business funds from personal accounts, which is essential for maintaining the LLC's limited liability protection.

Traditional US banks, think Chase, Bank of America, or Wells Fargo, generally require the account opener to appear in person at a US branch with two forms of identification, proof of a US address, and the EIN letter. Some branches are more accommodating than others, but the in-person requirement is a hard stop for most non-residents who are not planning a trip to the US.

The alternative that has become standard for non-resident LLC owners is applying through US fintech business account providers. Mercury, Relay, Brex, and Wise Business all offer accounts that can be opened remotely. Each has its own eligibility criteria, restricted country lists, and document requirements, but the general baseline is your EIN confirmation letter (CP 575 or 147C), articles of organisation, operating agreement, and a passport or national ID for the owner.

Approval is never guaranteed. Providers run their own compliance checks, and some exclude certain countries, industries, or business models entirely. A genuine, accurate business description on your application helps: never misstate your activities or ownership to a bank. Misrepresentation risks account closure, fund freezes, and potential legal consequences.

Traditional banks versus US fintech accounts

The choice between a traditional bank and a fintech account is not purely about convenience. Each option has trade-offs worth understanding before you commit.

Traditional banks offer FDIC insurance up to $250,000, physical branch access if you do visit the US, and broader lending products down the line. They also carry higher friction: minimum balance requirements, monthly fees, slower onboarding, and that in-person visit. For a non-resident running a lean online business, these extras may not justify the effort.

Fintech business accounts typically offer faster onboarding (sometimes within days), lower or zero monthly fees, integrated payment tools, and remote access from anywhere. The trade-off is that some fintech providers are not themselves banks but partner with FDIC-insured institutions, so you should verify that your deposits are covered. Feature sets also change frequently: a provider that accepted your country of residence last year may update its restricted list this year.

Many non-resident founders open a fintech account first to get operational, then add a traditional bank account later if the business grows to the point where lending or in-branch services become valuable. This staged approach avoids the initial bottleneck without closing off future options.

What to have ready, and in what order

Sequence matters. Doing things out of order creates delays and sometimes forces you to restart steps. Here is the correct order of operations:

1. Form the US LLC in your chosen state. You will receive articles of organisation and should prepare an operating agreement.
2. Obtain the EIN using Form SS-4 via fax, mail, or the international phone line. You need the LLC to exist before applying.
3. Open the US business bank account using the EIN confirmation, formation documents, operating agreement, and your passport.
4. Note your annual filing obligations from day one, specifically the Form 5472 and pro-forma Form 1120 that the IRS requires from foreign-owned single-member LLCs.

Cosmos helps non-resident founders move through this sequence with its licensed US partners, from state formation through EIN acquisition to banking introductions. Having a coordinated process avoids the common trap of forming an LLC in one place, chasing an EIN through another, and then discovering your banking application is missing a document that should have been prepared at step one.

Staying compliant once you are set up

Getting the LLC, EIN, and bank account open is not the finish line. Non-resident-owned US LLCs have ongoing obligations that, if missed, carry real penalties.

The most critical annual requirement is the Form 5472 with a pro-forma Form 1120, due by 15 April each year (or the extended deadline if you file for an extension). This form reports transactions between the LLC and its foreign owner. The penalty for failing to file, or filing late, is $25,000 per form as of 2026. That is not a typo: the IRS treats this seriously.

Beyond federal filings, your state of formation may require an annual report and a franchise tax or similar fee. Registered agent services must be maintained, and your operating agreement should be kept current if ownership or management changes. If you close the LLC, there is a formal dissolution process to follow rather than simply abandoning the entity.

Keep clean records of every transaction flowing through the US bank account. Separate business and personal spending. If your revenue triggers effectively connected income, consult a US-qualified tax adviser about whether you need an ITIN and a personal return.

Frequently asked questions

Can I get an EIN without an SSN as a non-resident? Yes. International applicants file Form SS-4 by fax, mail, or the IRS international phone line. No SSN or ITIN is required. The foreign owner is listed as the responsible party.

Do I need to visit the US to open a business bank account? Not necessarily. Several fintech providers, including Mercury, Relay, and Wise Business, accept remote applications from non-resident LLC owners. Traditional banks typically require an in-person visit.

Is an ITIN the same as an EIN? No. An EIN identifies the business entity. An ITIN identifies an individual for personal tax filing purposes. You only need an ITIN if you have a personal US tax filing obligation.

What happens if I do not file Form 5472? The IRS can assess a $25,000 penalty per form, per year. This obligation applies to all foreign-owned single-member LLCs regardless of revenue.

Which US state should I form my LLC in? Wyoming, Delaware, and New Mexico are popular for non-residents due to privacy provisions, low fees, and no state income tax on out-of-state revenue. The best choice depends on your specific situation.

Getting an EIN without an SSN as a non-resident is entirely possible, and so is opening a US bank account remotely, provided you follow the right sequence and prepare the correct documents. The process is not complicated, but it is unforgiving of mistakes: a missed filing, a mismatched document, or an inaccurate business description can set you back weeks or trigger penalties.
