Setting Up an LLC with a Bank Account: The Route to a US Business Account

The company is set up in two days. The account is the part where projects actually fail, not because the bank rejects you, but because the documents do not tell the story of what you actually do.

What you need first

Without an EIN, nothing works. The Employer Identification Number is the company's tax number with the IRS, and every bank requires it. It can also be applied for without a US Social Security number; expect around two weeks.

• Articles of Organization from the state of formation
• EIN confirmation from the IRS
• Operating Agreement with a clear ownership structure
• Passports of everyone involved
• Proof of address, usually a recent bill

The tiered model

There is no single US account. It makes sense to build up in three tiers, because each tier has different requirements.

Tier one consists of multi-currency accounts with US account details. They are available within days, work with the common payment service providers and, depending on the provider, also offer a European IBAN. In most cases this is enough to get started.

Tier two is a classic US business account that can be opened online and runs through FDIC-insured partner banks. Here the bank examines your business model much more closely.

Tier three is the branch bank. It only comes into question once the company has a history, in our experience from around six months. After about twelve months, this opens up access to the US credit system, including business credit cards. Pure fintech accounts do not offer this route.

How long it takes

The timeline is why we advise clients not to leave the account question until the end. If you form the company in January and expect customer payments in February, your planning is too tight.

Why applications fail

• The business model remains unclear. If you cannot explain in two sentences what money comes in for, you will be rejected
• The stated business activity does not fit. If your formation documents say something different from your website, a contradiction arises
• The source of funds is undocumented. Larger incoming payments without a traceable origin lead to queries
• The ownership structure is nested. Every additional layer lengthens the review
• Expectation and reality diverge. If you state USD 50,000 in monthly revenue and then move USD 5,000, you will stand out in monitoring

What the bank actually wants to see

Banks do not check documents; they check plausibility. Prepare one page that answers the following questions: what does the company sell, to whom, in which countries, in which currencies, with which typical amounts, and where does the start-up capital come from?

This one page decides success more often than any form. Supplement it with contracts, invoices or a website that tell the same story.

If the bank rejects you

A rejection is not an exclusion, but it should not be ignored. If you submit the same incomplete application to three more banks, you collect three more rejections.

• Ask for the reason, even if the answer is brief
• Close the identifiable gap before you apply again
• Change the tier, not just the provider: a fintech account is often a more realistic entry point than a branch bank
• Let some time pass between two attempts and build up a history in the meantime

In practice, the most common reason is not risk but incompleteness. That is good news, because that is exactly what you can work on.

Separating private and business

Business income belongs in the company account; private expenses do not. That sounds obvious, but it is regularly mixed up in single-member companies, especially when the LLC is treated as transparent in the US anyway.

Separation is nevertheless important. It supports the bookkeeping, it presents a consistent picture to the bank, and it is the basis of any later tax assessment. If you mix the company account and your private account, you may yourself provide the argument for not treating the company as a separate entity.

What a US account is not

It is not a tool for concealment. Although the US does not participate in the Common Reporting Standard, it exchanges data with the DACH countries via FATCA. If you are resident in Germany, you must declare the account and the shareholding anyway.

And it is not a substitute for clarifying your tax position. A working account says nothing about how your country of residence classifies the company; more on this under US LLC taxes in Germany.

How we assess this

From our client work: the order is the most common mistake. Many first choose the state and the cheapest business activity and only realise at the bank meeting that neither fits the business. Correcting this then costs fees and weeks.

Please note: only the bank can approve an account. Any provider that guarantees an account is promising something it cannot deliver. The application can be prepared, but the decision cannot be made for you.

Our advice: think about banking before the formation. Which countries do your payments come from, which amounts are typical, which activity describes your business correctly: these answers belong in the formation documents, not only in the account application.

Clarify before applying

• Do you have the EIN?
• Can you explain your business in two sentences?
• Does the activity in the formation documents match it?
• Can you document the origin of the start-up capital?
• Do you have contracts, invoices or a website as evidence?

As of 1 September 2026. The final decision on opening an account rests solely with the respective bank.
