For most UK founders breaking into the US market, the quickest way to get your finances in order is through a modern fintech platform like Mercury or Relay. Their entire process is built for remote founders, making them the most practical starting point for getting your US venture off the ground fast.

Your Guide to US Banking as a UK Founder

Choosing a US bank is one of the first—and most critical—decisions you'll make when expanding your business. This isn't just about ticking a box on your to-do list; it's about laying the financial foundation for everything that comes next, from paying your US team to managing taxes and scaling your operations. This guide will help you navigate the options and choose the right financial partner for your journey Stateside.

The US retail banking market is enormous and remarkably resilient. With a projected compound annual growth rate (CAGR) of 4.00% between 2025 and 2033, the demand for transactional accounts is solid. The fact that the top five banks hold over 50% of the market share means you’re tapping into a well-established and battle-tested infrastructure.

Navigating Your Banking Choices

For a UK-based founder launching a new US entity, the path of least resistance almost always points toward a digital banking platform. They are specifically designed for people in your exact situation—needing to open an account without setting foot in the US. The onboarding is entirely remote, typically just requiring your company formation documents and an Employer Identification Number (EIN).

If you haven't secured your EIN yet, don't worry. It's a standard part of the process, and we've put together a straightforward walkthrough here: What Is an EIN Number and How Do UK Founders Get One.

But what works on day one might not be the right fit for year three. As your business matures, you'll likely find yourself needing more sophisticated financial tools. A relationship with a traditional banking giant like Chase or Bank of America can become essential for accessing:

Substantial business loans or lines of credit
Advanced treasury and cash management services
In-person branch support for complex financial transactions

Your first bank doesn't have to be your forever bank. We often see founders start with a nimble fintech to get operational quickly, then layer in a relationship with a traditional bank once they have a stronger foothold in the US and require more complex financial products.

To make sense of the landscape, we’ve broken down the main options below. This should give you a clear idea of where to start based on your immediate and future needs.

Quick Comparison of US Bank Types

Bank Type	Best For…	Key Advantage	Who Should Use It?
Fintech Bank	Early-stage remote operations	Fast, 100% remote setup	SaaS, E-commerce, and digital service founders.
Traditional Bank	Scaling and long-term growth	Access to credit and full banking services	Founders who plan to build a physical US presence.
International Bank	Complex global operations	Seamless cross-border money management	Established companies with multinational footprints.

Understanding Your US Banking Options

Before we jump into a head-to-head comparison of the best US bank accounts, it's important to get the lay of the land. The American banking world offers a few different paths for UK founders, and the right one for you really boils down to your business model, how quickly you need to get moving, and what your long-term plans are. For non-residents, the choices generally fall into three buckets: the big traditional banks, the newer fintech platforms, and the global international players.

Each route comes with its own mix of trade-offs, balancing things like remote setup, the depth of services offered, and how well they'll support you as you grow. Getting this first decision right will make managing your US finances infinitely easier, both on day one and five years down the road.

Traditional Banks: The Powerhouses

We’re talking about the giants of American finance—names like JPMorgan Chase, Bank of America, and U.S. Bank. With assets in the trillions, these institutions are the absolute bedrock of the US financial system. Their main strength? Their physical footprint and the sheer breadth of what they can do for you.

This is the path you'll want to consider if you foresee needing:

Complex Lending: If you’re aiming for significant business loans or lines of credit, building a relationship with a traditional banker is often non-negotiable.
In-Person Services: For businesses dealing with large cash deposits, needing certified checks, or wanting face-to-face advice on treasury management, having a local branch is a game-changer.
Integrated Wealth Management: As your business finds its footing and becomes profitable, these banks can seamlessly blend your corporate and personal financial strategies.

The biggest hurdle for a UK founder, however, is the friction of just getting an account open. Most of these banks enforce strict "Know Your Customer" (KYC) rules that almost always require an in-person visit to a US branch to sign the final paperwork. It’s certainly not impossible, but it does require a trip across the pond.

Fintech Platforms: The Digital Natives

Platforms like Mercury and Relay have completely rewritten the rulebook for international founders. They were designed from the ground up for a global, remote-first world, and their entire model is built on speed, convenience, and accessibility.

For most UK founders running SaaS, e-commerce, or consulting businesses, these platforms are the best place to start. The application is entirely online and can usually be completed from the UK in a matter of days. They also feature slick integrations with modern accounting tools like Xero and QuickBooks, making your bookkeeping far less of a headache.

While fintechs offer incredible speed to get you up and running, their service list is typically more focused. You won't find physical branches, and they may have limits on more complex services like major loans or international trade finance, which could become a hurdle as your business scales.

International Banks: A Global Bridge

The third route is to work with an international bank that has a major presence in both the UK and the US, like HSBC or Barclays. On paper, this seems like the perfect solution—using your existing UK banking history to smooth the way for a US account. The reality, I've found, is often a bit more complicated.

The US and UK divisions of these banks frequently operate as separate legal entities, each with its own compliance and onboarding procedures. A long-standing relationship in the UK helps, but it’s no guarantee of a simple, remote opening for your new US company. This path tends to work best for larger, established UK companies setting up a US subsidiary, not so much for a brand-new startup.

Comparing the Top US Bank Accounts for UK Entrepreneurs

You've successfully formed your US company. Now comes the next, and often trickier, hurdle: opening a US bank account from across the pond. Forget the generic "best bank" lists you've seen online. For a UK founder, the right choice isn't about who has the most branches; it’s about who will actually say "yes" to your application.

The decision really boils down to a few critical questions. Can I do this from my home office in Manchester? What paperwork will they demand? And will this account actually help my business run smoothly, or will it create more headaches?

Let's break down the real-world options, comparing two of the most popular fintechs, Mercury and Relay, against a traditional banking giant, Chase.

The Non-Resident's Checklist: What Really Matters

When you're evaluating banks as a non-resident, your priorities are flipped upside down compared to a US-based founder.

You need to focus on what I call the "deal-breaker" criteria:

Remote Opening: This is the big one. Can you get the entire application done and dusted from the UK, or are you looking at a flight to the States? For many, this is the first and last question that matters.
Documentation: Will the bank accept your application with just your company's EIN (Employer Identification Number), or are they going to insist on a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN)? This single point separates most fintechs from traditional banks.
True Costs: Look past the advertised $0 monthly fee. You have to dig into the wire fees—both domestic and international—and any surprise charges for things you’ll actually use.
Tech Stack Fit: How well does the account plug into the tools you already use? Seamless connections to QuickBooks, Xero, Stripe, and Shopify are non-negotiable for operational efficiency.
Growth Potential: Think a year or two down the line. Will this bank be able to support you with things like venture debt, business loans, or more complex treasury management when you need them?

Fintech Challengers vs. a Traditional Giant

For most UK entrepreneurs starting out in the US, the choice is between a modern, nimble fintech platform and an old-school, powerhouse bank. They both get you a US account number, but the experience and long-term potential are worlds apart.

To give you a clearer picture, we've put three of the most common choices side-by-side.

US Bank Account Feature Comparison for UK Founders

Here’s a quick-glance comparison of the key features that matter most to a founder based outside the US. This table should help you quickly see how the options stack up based on your immediate needs.

As you can see, the "best" bank is entirely dependent on your business model and your willingness (or ability) to travel to the US. The specs on a page only tell half the story, though. Let's see how these accounts actually perform in practice.

Real-World Scenarios: Which Bank for Your Business?

The right financial partner for a lean SaaS company is completely different from the one for an ambitious e-commerce brand.

Scenario 1: The Bootstrapped SaaS Startup

You're a UK-based founder with a slick B2B SaaS product. Your customers pay via Stripe, your team is fully remote, and your main costs are software and marketing. You need to be up and running yesterday, with zero fuss.

Your Best Bet: Mercury. Their entire process feels like it was designed for you. You can apply from the UK with your EIN and company docs, get approved in a matter of days, and have a live account ready to connect to Stripe. Their API is also a game-changer for automating financial tasks as you grow.

Scenario 2: The Collaborative Digital Agency

Now, imagine you're running a creative agency with a co-founder in London and a couple of contractors in the US. You need to manage client-specific budgets and give your team debit cards for expenses, all while keeping a tight grip on who's spending what.

Your Best Bet: Relay. While it also offers a quick remote setup, Relay's superpower is its team-based financial management. You can create up to 20 separate checking accounts to wall off funds for projects and issue up to 50 virtual or physical debit cards with custom spending limits. It’s a level of control that's hard to find without paying for separate, expensive software.

Scenario 3: The E-commerce Brand with Big US Plans

Finally, picture an e-commerce brand that's hit a nerve in the US market. You're looking at leasing a warehouse, hiring a small US team, and you know you'll need a line of credit for inventory buys sooner rather than later.

Your Best Bet: Chase. Yes, it means booking a flight. But for this kind of business, establishing a relationship with a major institution like Chase is a strategic investment. Their Chase Business Complete Banking account is solid, but the real prize is what comes later. Building that history opens the door to the business loans, credit lines, and robust treasury services that fintechs simply can't match.

The most critical difference is this: fintechs like Mercury and Relay are built to approve non-residents without an SSN or ITIN. Traditional banks, even when you show up in person, often get nervous and can refuse to open an account with only an EIN. This makes the fintech route the only realistic starting point for many founders.

Ultimately, your choice depends on balancing today's needs with tomorrow's goals. Fintechs offer unmatched speed and accessibility to get you off the ground remotely. But as your US operations grow more complex and require serious financing, a relationship with an established bank like Chase becomes a necessity.

At Set Up Stateside, we help founders navigate this exact decision every day, ensuring your banking strategy is perfectly aligned with your business ambitions from day one.

How to Open Your US Business Bank Account

Opening a US bank account from the UK feels like a huge hurdle, but I’ve seen countless founders get it done. The whole process really breaks down into two major stages: first, getting your legal house in order, and second, choosing your banking path. You can either go fully remote with a fintech or fly to the US for an in-person meeting at a traditional bank.

Think of it less as filling out forms and more as making your new company a real, bankable entity in the eyes of American financial institutions. Getting this right from day one is crucial—it avoids frustrating delays and builds a solid financial foundation for your US venture.

Foundational Steps Before You Apply

Before you even think about talking to a bank, you need to get two critical documents sorted. These are non-negotiable and form the bedrock of your business’s legal identity in the US.

Form a US Business Entity: Your first move is to officially register your business in a US state. For nearly all UK founders, this means setting up a Limited Liability Company (LLC) or a C Corporation. This step provides the Articles of Incorporation or Certificate of Formation that every bank will ask for.
Secure an Employer Identification Number (EIN): The EIN is your company's unique, nine-digit tax ID number from the IRS. It's the business equivalent of a Social Security Number, and without it, no US bank will open an account for a non-resident.

With these two documents in hand, you’re officially ready to approach the banks. Your next decision comes down to your operational plans and whether you can physically travel to the United States.

This simple flowchart lays out the fundamental choice you're facing.

As you can see, your ability (or desire) to open an account remotely is the first and most important filter. It immediately points you toward either a modern fintech or a traditional bank.

The Remote Onboarding Pathway

Let’s be honest, for most UK founders, the fully remote route is the only one that makes sense. It’s practical, fast, and exactly what fintechs like Mercury and Relay were designed for.

You’ll start by filling out an online application, which usually takes less than an hour. During the sign-up, you'll need to upload digital copies of your key documents.

Required Documents for Remote Opening:

Founder's Government ID: A crisp, color copy of your valid UK passport is the standard here.
Company Formation Documents: This will be your Articles of Incorporation (for a C Corp) or Articles of Organization (for an LLC).
EIN Confirmation Letter: The official CP 575 or 147C letter you got from the IRS is the mandatory proof of your tax number.

Pro Tip: When the application asks for a company address, use your US Registered Agent address. This is standard practice and completely above board. Trying to use a UK address often triggers compliance red flags and can get your application rejected.

After you submit everything, the bank's compliance team will review your application. They might ask for a quick video call or a selfie to verify your identity. If all your paperwork is in order, you can expect to have a fully functional account within a few business days.

The Traditional In-Person Pathway

If your business plan requires traditional financing, like an SBA loan, or you just need the robust services of a brick-and-mortar branch, then building a relationship with a big bank like Chase or U.S. Bank is the way to go. Just know that this path demands a lot more planning.

You'll have to schedule an appointment at a US branch well in advance. Then, you'll need to fly to the US for the meeting, bringing the original (or certified) physical copies of the same core documents mentioned earlier.

The in-person verification is far more intensive. The banker will scrutinize your passport and comb through your business formation paperwork. From scheduling the first meeting to getting a fully active account, be prepared for the process to take several weeks. For a much deeper dive into the specific documents and expectations, our complete guide to opening a business checking account has all the details.

Ultimately, choosing the right path is a strategic business decision. Whether you choose the convenience of a fintech or the long-term relationship potential of a traditional bank, showing up with your documentation prepared perfectly is what guarantees a successful outcome.

Common Banking Pitfalls for UK Founders to Avoid

Getting your US bank account approved is a huge milestone, but it's where the real work begins. Too many UK founders celebrate this win only to fall into a few common, and costly, operational traps. Knowing what they are is the best way to build a solid financial foundation for your US venture right from the start.

The first and most frequent mistake I see is mixing business and personal funds. It’s so easy to do—you’re on a business trip in the States and use the company card for a personal meal, or you pay a UK-based contractor directly from your US business account. This is called commingling funds, and it's a massive problem. It effectively tears down the "corporate veil" that separates you from your business, putting your personal assets on the line and creating a bookkeeping mess that can cost a fortune in accounting fees to fix.

The Hidden Costs of Poor Bookkeeping

Keeping clean and separate books isn't just about being organised; it's a legal requirement in the US. When personal and business transactions get tangled, your tax returns become a nightmare, and it's impossible to tell how your company is actually performing. This isn't a rookie mistake, either—a surprising number of small businesses trip up on basic financial management.

Get your financial discipline in order from day one:

Set up a formal process for paying yourself, whether it's a salary or an owner's draw.
Get a dedicated business credit card and use it for all company expenses.
Never, ever use the business debit card for personal spending. Not even for a coffee.

Another pitfall is glossing over software integrations. If your new bank account doesn't connect smoothly with your accounting software, like Xero or QuickBooks, you’re signing yourself up for hours of manual reconciliation. It's not just tedious work; it's a recipe for human error, which can lead to bad financial reports and incorrect tax payments.

I always tell founders: evaluate a bank’s tech just as carefully as you evaluate its fees. A clunky app or broken integration creates operational drag, and that directly costs you time and money. Always test or verify a bank’s integration quality before you commit.

Navigating Sales Tax and Scalability Traps

Sales tax is a minefield, especially for e-commerce and SaaS founders. A lot of people assume that because their company is registered in Delaware or Wyoming, their tax obligations are limited to that one state. This is dangerously incorrect.

In the US, your obligation to collect and pay sales tax (known as "nexus") is determined by your economic activity. If you hit a certain sales threshold in a state, you have nexus there. I've seen UK-based founders trigger tax filing requirements in 10 or more states without ever stepping foot in the country. Ignoring this can result in crippling penalties and back-tax bills.

Finally, don't get caught in the scalability trap. A fintech account is fantastic for getting off the ground quickly. But as your business grows, you might hit a wall.

Signs you might be outgrowing your initial fintech bank:

You start receiving a lot of physical checks from US customers.
You need more advanced treasury or cash management services.
You're ready to apply for a significant business loan or line of credit.

Starting with a fintech is a smart, agile move. But the sharpest founders are already thinking two steps ahead. The best approach is often a hybrid one: use a fintech for speed now, but plan to build a relationship with a traditional bank later to access more sophisticated financial tools as you scale. This foresight saves you from the headache of moving your entire financial setup right when your business is hitting its growth stride.

The Right Banking Strategy for Your US Business

Choosing a bank for your US venture isn't about finding the one "best" account. It's about building a financial foundation that matches where your business is today—and where you plan to take it. After guiding hundreds of founders through this process, we've found that the best approach balances your immediate needs with your long-term ambitions.

There's no magic bullet, just a smart, phased strategy. For most UK founders launching a digital business, the path of least resistance is also the most effective. Your first priority is getting up and running quickly and remotely, which makes a fintech platform the clear winner out of the gate.

The Fintech-First Approach

If you’re running an e-commerce store, SaaS company, or a digital agency, your opening move should be simple: start with a fintech partner like Mercury or Relay. These platforms were practically built for non-resident founders. They completely remove the biggest hurdle—the need to fly to the US—letting you get your account live in days.

This strategy gets you:

Immediate Operations: You'll have US account details ready in no time, so you can start taking payments and managing your cash flow.
Low Overheads: Most of these accounts have no monthly fees or minimum balance requirements, which is a huge relief for any new venture.
Tech-Forward Integrations: They connect beautifully with the tools you already use, like Stripe, Shopify, and your accounting software.

Think of the fintech-first strategy as your launchpad. It’s an agile move that solves your most urgent problem—getting a functional US bank account from the UK—without the cost or complexity of traditional banking.

But a launchpad is just for liftoff. As your business scales and its needs get more complex, relying solely on a fintech can start to feel restrictive.

The Hybrid Banking Strategy

The most successful founders we work with at Set Up Stateside eventually adopt a hybrid model. They kick things off with a fintech for speed and convenience, then add a relationship with a traditional bank, like Chase, once they have a real foothold in the US. This gives you the best of both worlds.

This is the path for you if you plan to:

Hire a US-based team and need robust local payroll.
Seek traditional financing like a business loan or line of credit.
Establish a physical presence, like an office, warehouse, or storefront.

By starting with a fintech, you get your business off the ground without delay. Then, when the time is right, you can plan a single, strategic trip to the US to open an account with a major bank. This approach ensures your financial infrastructure supports your business at every stage, from scrappy startup to established enterprise.

Frequently Asked Questions

When you're launching a US business from the UK, questions about banking are bound to come up. It's a different system, after all. We've heard just about every query from founders over the years, so we’ve gathered the most common ones right here to give you some straight answers.

Can I Open a US Business Bank Account from the UK Without an SSN?

Yes, you can. This is a huge relief for most non-resident founders. You won't need a Social Security Number (SSN) as long as your US company has its Employer Identification Number (EIN).

Modern digital banks like Mercury and Relay are built for this exact scenario and specialize in onboarding international founders with just an EIN. Some of the big, traditional banks might allow it too, but only if your US entity is set up perfectly and all your paperwork is flawless.

Do I Need a Physical US Address to Open an Account?

You absolutely need a US business address, but crucially, it doesn't need to be a physical office you're working from.

The registered agent address or virtual business address you get when forming your US company is usually sufficient for both banking and legal mail. Just be aware that banks almost universally reject P.O. boxes, so make sure your address provider gives you a proper street address.

How Long Does the Account Opening Process Take?

The timeline really depends on the bank you choose. With a fintech partner, it can be remarkably quick. If you have your passport, EIN confirmation letter, and company formation documents ready to go, you could get approved in just a few business days.

Going the traditional route with a high-street bank is a different story. Expect the process to take several weeks, especially if you have to mail original documents or—in some cases—fly to the US for an in-person appointment. The logistics alone can add significant delays.

Choosing the right banking partner is one of the most important first steps in your US expansion. Set Up Stateside offers hands-on guidance for UK founders, from company formation and getting your EIN to selecting the perfect bank for your business. Find out how we can help you get started.
