What Documents You Need to Open US Business Banking
Opening a US business bank account from Europe is entirely doable, but only if you have the right paperwork ready before you apply. Here is exactly what banks ask for and why.
Why documentation matters more when you are not a US resident
US banks are required to verify who owns a business and where the money is coming from. For a resident founder with an SSN and a US address, that verification is quick. For a non-resident founder, the bank has to piece together your identity, your company's legal existence, and your ownership structure using documents alone. Missing or mismatched paperwork is the single biggest reason non-resident applications get delayed or rejected, not the fact that you live in Europe.
The good news is that the list is short and predictable. Once you know what is needed, you can gather everything in a few weeks and apply with confidence.
The core document checklist
| Document | What it proves | Notes for non-residents |
|---|---|---|
| Articles of Organization (or Certificate of Formation) | Your LLC legally exists | Issued by the state, usually Wyoming, Delaware or similar. Keep the state-stamped or filed copy, not just your draft. |
| Operating Agreement | Who owns the LLC and how it is managed | Not always filed with the state, but banks often want to see it to confirm you are the beneficial owner. |
| EIN confirmation letter (CP 575 or 147C) | Your business has a federal tax ID | Issued by the IRS after you file Form SS-4. Non-residents without an SSN or ITIN can still get an EIN, typically by fax or mail. |
| Passport | Personal identity of the owner(s) | A clear, in-date passport scan is usually sufficient for online-first banks. |
| Proof of address | Where you and the business are based | Personal proof (utility bill, bank statement) for you, plus a US business address, often a registered agent or virtual mailbox address. |
| ITIN (in some cases) | Tax identification for the individual owner | Not every bank requires it, but some do, especially traditional banks. An ITIN is for people who cannot get an SSN and does not require a US visa. |
Formation documents: get the details right
Your Articles of Organization need to match your EIN application exactly. If your LLC name, state, or formation date differs between the two, expect delays. Wyoming is the most common choice for non-US founders because it is inexpensive, has no state income tax, and its registered agents are used to working with international owners.
Keep both the state-filed version and any receipt of payment. Some banks ask for a certificate of good standing if your LLC is more than a year old, so it is worth requesting one from your state before you apply if your formation is not brand new.
The EIN letter is non-negotiable
You cannot open a US business bank account without an EIN. The EIN comes from filing Form SS-4 with the IRS. Non-residents without an SSN or ITIN can still apply, generally by fax or mail rather than online, since the IRS's online EIN tool is restricted to applicants with a US taxpayer identification number.
Once approved, the IRS sends confirmation as either a CP 575 letter (issued once, on first approval) or a 147C letter (a reissued confirmation you can request later if you lose the original). Banks will accept either. Keep a digital copy the moment you receive it, because you may need it again for tax filings, payment processors, and card applications.
ID and proof of address: what actually counts
For personal identification, a passport is almost always enough for the digital-first banks that work well with non-residents, such as Mercury, Wise, and Relay. These platforms are built for remote onboarding and do not require you to visit a branch or hold an SSN.
Proof of address is where founders most often get confused. You typically need two separate things:
- Your personal residential address in Europe, shown through a recent utility bill, bank statement, or government correspondence.
- A US business address for the LLC, usually provided by your registered agent or a virtual mailbox service. This is not the same as your home address and does not need to be a place you have ever visited.
Some banks also ask for a brief description of your business activity and expected transaction volume. Have a one or two sentence explanation ready, since vague answers slow down approval more than the actual nature of the business does.
A complete, consistent document set is worth more than a perfect business plan when it comes to opening a bank account as a non-resident.
Do not forget the ongoing compliance side
Getting the bank account open is only half the picture. A foreign-owned single-member LLC is required to file Form 5472 together with a pro-forma Form 1120 every year, even if the company had no income and did no business. This is an information return, it reports transactions between the LLC and its foreign owner rather than calculating tax owed on its own. Skipping it is expensive: the IRS penalty for failing to file Form 5472 starts at $25,000, and it applies whether or not you owed any tax.
This is where a done-for-you setup earns its keep. Founders Credit handles the LLC formation, EIN application, ITIN where needed, and the bank and card applications as one coordinated process, so the documents banks expect are consistent from day one and nothing falls through the cracks on the compliance side later.
A simple pre-application checklist
- State-filed Articles of Organization matching your EIN application exactly
- Signed Operating Agreement naming the beneficial owner(s)
- EIN confirmation letter (CP 575 or 147C) from the IRS
- Valid passport for each owner
- Personal proof of address from your home country
- US business address from a registered agent or virtual mailbox
- ITIN, if the bank you are applying to requires one
- A short, clear description of your business activity
Gather these before you apply rather than during the process. Banks that serve non-residents move quickly once they have a complete file, and slowly when they have to chase you for one more scan.
Frequently asked questions
Do I need an ITIN to open a US business bank account?
Not always. Many digital-first banks that work with non-residents, such as Mercury or Wise, will open an account with just your passport and EIN letter. Some traditional banks do require an ITIN, so it depends on where you apply.
Can I open a business bank account before I receive my EIN letter?
No. The EIN is one of the core requirements for every US business bank account, so you need the confirmation letter, either the CP 575 or a reissued 147C, in hand before applying.
Does my registered agent's address count as my proof of address?
It can count as your business address for the LLC, but banks also want a separate personal proof of address from your home country, such as a utility bill or bank statement in your own name.
How long does it take to gather everything needed for a bank application?
Formation and EIN approval typically take a few weeks combined, and personal documents like a passport scan and proof of address are usually already on hand. Most founders can be application-ready within three to six weeks.
What happens if I open the bank account but never file Form 5472?
Form 5472 must be filed annually alongside a pro-forma Form 1120 for any foreign-owned single-member LLC, even with zero activity. Failing to file carries a penalty starting at $25,000, so it should be treated as a fixed yearly obligation, not an optional step.
