Documents Required to Open Company Bank Account in the US

Alright, let's break down exactly what you'll need to open your US company bank account. Getting your paperwork in order upfront is the single most important thing you can do to make this process go smoothly. At its core, the bank just needs to confirm four things.

Think of it like this: the bank has a compliance checklist, and your job is to give them everything they need to tick their boxes. Your application rests on (1) your company's official formation documents, (2) its unique tax number, (3) personal ID for the people in charge, and (4) proof of a US business address.

Your Essential US Bank Account Document Checklist

Putting together the documents for a US bank account can feel a bit like a scavenger hunt, but it’s straightforward once you know what you’re looking for. The bank’s goal is simple: they need to verify that your business is real, that you are who you say you are, and that your company has a legitimate presence in the US.

These core documents are non-negotiable, whether you're walking into a major national bank or using a newer fintech platform.

The Four Pillars of Your Application

Let’s group these required documents into four key categories. This is how the bank sees your application.

• Business Formation Documents: This is your company's "birth certificate." For an LLC, it's your Articles of Organization. If you’ve set up a corporation, you'll need your Articles of Incorporation. This is the first piece of proof that your company legally exists.

• Federal Tax ID Number: This is your Employer Identification Number (EIN). It acts like a Social Security Number but for your business. The IRS issues this unique nine-digit number, and it’s a hard requirement for all corporations and most LLCs.

• Personal Identification: The bank needs to know who has control over the account. You'll need to provide a valid, unexpired government-issued photo ID. For most UK founders, a passport is the gold standard here.

• Proof of US Business Address: Your company must have a physical address in the US. Critically, this cannot be a P.O. Box. Many founders based outside the US use the address provided by their Registered Agent or a dedicated virtual office service for this.

This simple flowchart shows how these pieces fit together. You’re providing credentials for the business itself, for you as the owner, and for its US location.

As you can see, it's about proving the identity of both the business entity and its owners.

For UK founders, this checklist is your starting point. You're joining a well-trodden path—over 1.2 million foreign-owned businesses obtained an EIN between 2019 and 2023 to operate in the US.

Major banks like Chase and Bank of America are quite strict about this. They will always ask for the company formation documents and the EIN, plus a verifiable US address and personal IDs for everyone who will be on the account. You can find more details on these policies directly from the banks; here are the international banking requirements from Bank of America as an example.

Core Document Checklist for US Business Bank Accounts

To make things even clearer, here’s a summary table of the essential documents every founder needs to have ready. Think of this as your master checklist before you start any application.

Document Category	Specific Document(s) Needed	Purpose
Business Identity	Articles of Organization (for LLCs) or Articles of Incorporation (for Corporations)	Proves the company was legally formed and registered with a US state.
Tax Identity	IRS Letter CP 575 or 147C	Confirms your company’s unique Employer Identification Number (EIN).
Personal Identity	Valid Passport (for non-residents) or Driver's License (for US residents)	Verifies the identity of each person who owns or controls the company.
Physical Location	Utility bill, lease agreement, or virtual office/registered agent address	Demonstrates a verifiable physical business address within the United States.

Having these four items scanned and ready to go will put you in a strong position and prevent most of the common delays and rejections that founders run into.

Alright, let's get into the nitty-gritty: the paperwork. When you apply for a U.S. bank account, you’re essentially proving two things: that your company legally exists and that it's registered with the U.S. tax authorities. The bank needs to see your company’s "birth certificate" and its unique tax ID. These are the absolute non-negotiables.

Without these two core documents, your application is dead in the water. They are the primary documents required to open a company bank account and the first things any banker will ask for to confirm your business is a real, operational entity.

Your Company's Legal "Birth Certificate"

First up, you have to prove your company is officially on the books. This is done with the formation document that was filed with and approved by the state. The exact name of this document changes depending on your business structure.

• For an LLC: You'll need your Articles of Organization. This is the official paper that brought your Limited Liability Company into existence.

• For a Corporation: You'll be looking for your Articles of Incorporation. It serves the same purpose, proving your corporation was legally formed and registered.

The bank is going to check this document for a few key details: your official company name, which state you registered in, and that your company is listed as active or in "good standing." I've seen countless applications get instantly rejected because of a simple mismatch between the company name on the application and the one on the official articles. Get it right.

Key Insight: These formation documents aren't just bureaucratic fluff. They're the legal firewall separating your personal finances from your business. For a bank, they’re proof that you're running a structured, legitimate operation, which is a huge part of their risk assessment.

The All-Important Employer Identification Number (EIN)

If your formation document is the birth certificate, then the Employer Identification Number (EIN) is your company’s unique tax ID. Think of it like a Social Security Number, but for a business. It’s a nine-digit number issued by the IRS, and you absolutely must have one to open a business bank account.

This is how the bank reports your account's financial activity to the IRS. There's simply no way around it.

For UK founders and other non-residents without a U.S. Social Security Number (SSN) or ITIN, getting an EIN is a manual process. You'll need to fill out Form SS-4 and submit it the old-fashioned way—by fax or mail. Be prepared for a wait, as it can take several weeks.

Once the IRS processes your application, they'll send you a confirmation letter, usually called a CP 575 notice. This letter is the gold-standard proof of your EIN. You will need to provide a clean copy to the bank, as it’s one of the most critical documents required to open a company bank account.

Your Company's Rulebook: The Operating Agreement

While not always legally required to form a single-owner LLC, almost every bank will ask to see your company's Operating Agreement (or Bylaws, if you have a corporation). Why? Because this document is the internal rulebook for your business.

It's essentially a private contract between the owners that spells out details the bank desperately needs to know:

• Who owns the company? It lists all the members (for an LLC) or shareholders and their ownership stakes.

• Who's in charge? It specifies who has the authority to make decisions, sign contracts, and, most importantly, open and manage a bank account.

From the bank's perspective, the Operating Agreement answers the question, "Who are we actually dealing with, and does this person have the power to control the company's money?" Without it, they have no way of knowing if you're the right person to be opening the account. For companies with more than one owner, it's an absolute must-have. Our guide on the Certificate of Formation dives a bit deeper into why these foundational documents are so important.

Proving Who You Are and Where You Operate

Alright, once your company formation and tax paperwork are in order, the bank's attention pivots to you—the person behind the business—and where your company actually operates. This stage is all about satisfying strict "Know Your Customer" (KYC) and anti-money laundering rules. Trust me, banks aren't trying to make your life difficult; they're legally obligated to verify who’s opening and controlling the account.

This means you’ll need to prove your own identity and show that your company has a legitimate U.S. address. Let's dig into what this really means, especially for founders coming from the UK.

Your Personal Identification: The Gold Standard

For every person who is an owner or will be an authorized signatory on the account, the bank is going to ask for a valid, government-issued photo ID. There's no getting around this.

For anyone who isn't a U.S. resident, including our UK founders, the absolute best and most widely accepted ID is your valid passport. While a U.S. resident might get by with a driver's license, your passport is the universal key. Just make sure it isn't expired and that any copy you provide is crystal clear.

The U.S. Address Requirement: A Common Hurdle

Now for what is often the biggest sticking point for non-resident founders: the U.S. address. Banks need a physical address for your business within the United States. This isn't just for sending mail; it's a fundamental legal requirement to establish that your company has a real footprint in the country for regulatory and tax reasons.

One thing to get straight right away: a P.O. Box will not work. Banks need a real street address where official and legal notices could, in theory, be delivered. This doesn't mean you have to go out and rent an expensive office. In fact, most founders based abroad handle this with one of two very practical solutions.

• Registered Agent Address: When you set up your LLC or corporation, you're required to have a Registered Agent in that state. Many of these services will let you use their address as your company's official business address. This is usually the simplest and most cost-effective route to take.

• Virtual Business Address: These services give you a real street address in a commercial building. They often come with handy features like mail scanning and forwarding, essentially creating a "digital mailbox" for all your U.S. business correspondence.

Whichever service you choose, the bank is going to want to see proof that you're entitled to use that address.

What the bank is really looking for is a clear link between your company and a verifiable physical location in the U.S. The document that forges this link is your service agreement or lease from the Registered Agent or virtual address provider. Think of it as proof of your company's stateside presence.

This document does the same job as a utility bill or an office lease would. It’s one of the most crucial documents required to open a company bank account when you're not a U.S. resident.

Before you sign up with an address provider, double-check that they offer a commercial address (not just a mailbox store) and that they can give you a formal service agreement or welcome letter. It needs to clearly state your company's name and the address they've provided. This simple piece of paper is often the final puzzle piece needed for a successful application. If you’re wondering which address to use when applying for your EIN, you can find more detailed advice in our guide on how to get an EIN verification letter. Keeping your address consistent across your formation documents, EIN, and bank application is key to avoiding headaches.

Choosing Your Banking Partner: Traditional vs. Fintech

Alright, you’ve wrestled with the paperwork and have your documents in order. Now for the million-dollar question: where do you actually open the account? Think of it like choosing where to shop—you can go to a massive, well-known department store or a nimble, modern online boutique. Both sell clothes, but the experience couldn’t be more different.

For UK founders, the choice boils down to two main routes: the old-guard traditional banks (like Bank of America or Chase) and the new wave of financial technology (fintech) platforms (like Mercury or Relay). The path you pick will dramatically affect how you use the documents required to open a company bank account.

The Traditional Bank Route

The big, household-name banks have been around forever. They offer a sense of security, sprawling branch networks, and a massive menu of financial products, from checking accounts to complex business loans. But for a founder sitting in the UK, this route comes with one giant, often deal-breaking, catch: the in-person visit.

Nearly all major U.S. banks require at least one person on the account to show up, passport in hand, at a physical branch to get things finalized. This means booking a flight to the States is almost always part of the process.

If you go this route, you'll need to pack your entire document arsenal for the trip:

• Your official, state-stamped Articles of Organization or Incorporation.

• The EIN confirmation letter from the IRS (Form CP 575).

• Your passport, and it's wise to bring a second form of ID just in case.

• Your company's signed Operating Agreement (for an LLC) or Bylaws (for a corporation).

• Proof of your U.S. business address, such as your Registered Agent service contract.

The whole affair can be slow, easily taking several weeks from your visit to the moment your account is actually active. The main benefit, of course, is that you get to talk to a real person if you hit a snag.

The Modern Fintech Alternative

Fintech platforms were practically built for founders like you. Their entire model is designed for a remote-first world, prioritising speed and convenience with a 100% online application. This makes them a perfect match for international entrepreneurs who can't just pop over to a branch in Chicago.

Key Takeaway: Fintechs have completely changed the game for non-resident founders. They use technology to verify documents online, eliminating the need for a branch visit and drastically reducing the time it takes to get an account open and operational.

This digital-first approach means you can upload everything from your desk in London or Manchester. The required paperwork is the same—they still need your formation documents, EIN, and ID—but the difference is how they handle it. It's all done through secure online portals.

This is a massive advantage. Fintechs have made opening a U.S. business account from abroad not just possible, but straightforward. It’s common to see accounts approved in just 1-3 business days, a world away from the 2-4 weeks you might wait with a traditional bank. Platforms like OFX and Airwallex have perfected this, accepting your ID, business registration, address proof, and EIN entirely online. They don't ask for minimum deposits and, crucially, bypass the in-person verification that still blocks 70% of non-resident applications at legacy banks.

A Head-to-Head Comparison

To make the choice clearer, let’s lay it all out side-by-side. The right option for you really depends on your immediate needs and long-term plans.

Traditional Bank vs. Fintech Platform: A Comparison for UK Founders

Feature	Traditional Banks (e.g., Chase, Bank of America)	Fintech Platforms (e.g., Mercury, Relay)
In-Person Visit	Almost always required for non-resident owners.	Never required; the process is 100% online.
Application Speed	Slow; can take 2-4 weeks or more for approval.	Fast; approval often happens in 1-3 business days.
Document Submission	Typically requires hard copies or in-person review.	Fully digital; upload scanned documents online.
Account Fees	Often have monthly maintenance fees, though they may be waivable.	Usually have no monthly fees or minimum balance requirements.
Best For	Founders who plan to be in the U.S. and want access to a physical branch network and a wider range of services like loans.	UK and other non-resident founders who need a fast, remote, and low-cost way to start banking in the U.S.

In short, if you value speed and remote convenience above all else, fintech is your answer. If you foresee needing in-person banking services or complex credit facilities down the road and don't mind the trip, a traditional bank might be worth considering.

Finalizing Your Application and Overcoming Hurdles

Alright, you’ve collected all your paperwork and picked out a bank. Now for the final push. Submitting the application might feel like the last step, but it's where small mistakes can cause big delays. Let's walk through a final review and talk about what to do if you hit a snag.

Think of your application as the bank's first impression of your business. Before you click "submit," one last detailed check can be the difference between a smooth approval and weeks of frustrating emails.

The Pre-Submission Checklist

Run through this quick list to spot the common little errors that trip up even the most prepared founders.

• Perfect Name Matching: Is your company's legal name exactly the same on your Articles of Organization, your EIN letter, and the application form itself? Even a missing "Inc." or a slight variation can cause a rejection.

• Crystal Clear Scans: Are all your uploaded documents easy to read? A blurry passport photo or an EIN letter where the text is cut off is an easy excuse for the bank to send your application back to the bottom of the pile.

• Valid IDs: Take a moment to double-check the expiration date on your passport. Banks are legally forbidden from accepting expired IDs, with no exceptions.

• Signed Agreements: If you're submitting an Operating Agreement or bylaws, have all the members or shareholders signed it? An unsigned agreement is just a draft, and the bank will treat it as such.

Getting this right from the start shows the bank you're organized and serious, making their job—and your approval—much easier.

Responding to Bank Requests and Rejections

Even with a flawless application, you might still get an email from the bank's compliance team. Don't worry; this is completely normal, especially for international founders opening a U.S. account.

Most often, you'll receive a Request for Information (RFI). This is usually something simple, like asking for a clearer copy of a document or a bit more detail on what your business does. The key is to respond quickly and give them exactly what they've asked for.

If you get an outright rejection, the first step is to find out why. Was it a simple document issue, like a missing signature? You can usually fix that and reapply. Or was it a bigger policy issue, like the bank deciding they're not comfortable with your specific industry? If it’s a policy problem, your best bet is to thank them for their time and move on to the next bank on your list.

Special Hurdles for UK Founders

Founders from the UK sometimes get hit with unique document requests. The most notable one is the potential need for an apostille.

An apostille is an official certification that makes a document from one country legally valid in another. Think of it as a government-backed "stamp of authenticity" that confirms your UK-issued document is legitimate for use in the U.S.

A U.S. bank might ask for an apostille on a UK document if they need that extra layer of verification. It isn't a standard request from every bank, but it’s a possibility you should be prepared for, particularly with older, more traditional banks.

This level of scrutiny is part of a global trend. Banks are under immense regulatory pressure, so they're being more thorough than ever. In fact, recent data shows that 75% of U.S. bank rejections for non-residents stem from incomplete documentation, especially a missing Operating Agreement that clearly shows who owns the company.

Frequently Asked Questions

When you're setting up a US company from the UK, a lot of questions naturally pop up about banking. Let's tackle some of the most common ones we hear from founders just like you.

Can I Use My UK Address for a US Business Bank Account?

The short answer is no, you can't. US banks have a strict requirement for a verifiable physical address in the United States. Think of it as their official point of contact for any legal or regulatory matters concerning your company.

This is a non-negotiable rule, and importantly, a P.O. Box won't work. But don't worry, this is a standard hurdle that’s easily cleared. Most international founders go one of two routes:

• A Registered Agent Service: When you form your company, your registered agent gives you an official address. Many banks accept this as your main business address.

• A Virtual Business Address: These services provide a real street address at a physical office building, and they'll even handle your mail for you.

Just be sure you have the service agreement handy, as the bank will want to see it as proof.

Do I Need an SSN or ITIN to Open the Account?

This is a big point of confusion, but the answer is clear: No, you do not need a personal Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN) to open a business account.

The bank's main concern is the company's tax identity, not your personal one. For this, they use your company’s Employer Identification Number (EIN). That’s the key number they need. Of course, they still need to verify who you are. For UK founders, your passport is the gold standard for personal identification.

How Long Does It Take to Open an Account Remotely?

The timeline really depends on where you apply. Choosing between a modern fintech platform and a traditional high-street bank will have a huge impact on your waiting time.

Key Insight: Fintechs are built for this. Platforms like Mercury or Relay are designed for a fully digital experience, so they can often review and approve an application within a few business days. Traditional banks, on the other hand, can take two to four weeks as their processes often involve more manual steps and reviews.

No matter which path you take, having all your documents required to open company bank account perfectly organized is the single best thing you can do to speed things up.

Is an In-Person Visit to the US Required?

Not anymore, thanks to modern banking solutions. This is probably the most critical difference between new fintechs and old-school banks. Companies like Mercury and Relay have built their entire onboarding process to be 100% online. This makes them a game-changer for international founders.

On the flip side, most big traditional banks like Chase or Bank of America still require at least one owner to show up in a branch, sign papers, and prove their identity in person. While they sometimes make exceptions, it’s not something you can count on.
