To open a business bank account in the United States you need four things at the counter: your business tax ID (an EIN, or your SSN for a sole proprietor), your formation or registration documents, a government-issued photo ID for every owner with 25% or more, and a beneficial-ownership disclosure required under federal banking rules. Most banks also ask for a small opening deposit and, for LLCs and corporations, an operating agreement or corporate bylaws. Have those in hand and a straightforward account can be opened in a single visit or one online session.
The list looks short, but the details change with how your business is legally structured, and getting the account open cleanly matters well beyond banking. From an underwriter's chair, your business checking account is the single most important financial record you own. Revenue-based lenders read your deposits, not just your credit score, so the account you open today is the record that funds you tomorrow.
Key takeaways
- You need four essentials to open a US business bank account: an EIN (or SSN for sole proprietors), formation documents, a government photo ID, and a beneficial-ownership disclosure.
- Federal Customer Due Diligence rules require banks to identify every owner of 25% or more, plus one controlling person.
- Required documents vary by entity: LLCs bring an operating agreement, corporations bring bylaws and a board resolution, sole proprietors bring a DBA registration.
- Opening deposits are typically small — often $25 to $100 — and some online accounts require none.
- Online and neobank accounts use the same document requirements as branches; only the verification is electronic — confirm FDIC coverage through the underlying bank.
- Your business checking account is the primary record revenue-based lenders underwrite; they read deposits and revenue over credit score.
- The most common cause of a frozen new account is a name mismatch between the EIN letter, state filing, and ID, or applying before state formation is approved.
The core checklist every business needs
Regardless of entity type, nearly every US bank will ask for the same foundation. Bring these and you have cleared 80% of the requirement:
- Employer Identification Number (EIN) — issued free by the IRS. A single-member LLC or sole proprietor without employees can sometimes use an SSN, but an EIN keeps business and personal finances separate and is strongly recommended.
- Government-issued photo ID — a driver's license, state ID, or passport for each person listed on the account and for each beneficial owner.
- Formation or registration documents — what you filed with your state (Articles of Organization for an LLC, Articles of Incorporation for a corporation, or a fictitious-name/DBA registration for a sole proprietor operating under a trade name).
- Beneficial-ownership information — under the federal Customer Due Diligence rule, banks must collect the name, address, date of birth, and ID number of anyone owning 25% or more, plus one person who controls the company.
- Opening deposit — often $25 to $100, though some accounts require more or none at all.
Bring originals or clear digital copies. Banks verify formation documents against state records, so the name on your paperwork must match exactly what you present.
What each entity type needs (documents by structure)
The extra documents depend entirely on how you are organized. Match your structure to the row below.
| Business type | Tax ID | Formation documents | Extra documents commonly requested |
|---|---|---|---|
| Sole proprietor | SSN or EIN | DBA / fictitious-name registration (if using a trade name) | Business license, if your city or county requires one |
| Single-member LLC | EIN | Articles of Organization | Operating agreement; state certificate of good standing |
| Multi-member LLC | EIN | Articles of Organization | Operating agreement naming all members; ID for each 25%+ owner |
| Corporation (C or S) | EIN | Articles of Incorporation | Corporate bylaws; board resolution authorizing the account |
| Partnership | EIN | Partnership agreement | DBA registration if operating under a trade name |
| Nonprofit | EIN | Articles of Incorporation | IRS 501(c) determination letter; board resolution |
If your state issues a certificate of good standing, ordering one before you go smooths the process — it confirms your business is registered and current on state filings.
A realistic example: what a new LLC brings to the branch
Consider, for example, a two-owner landscaping LLC opening its first business checking account. Here is what they walk in with and why each piece is asked for.
| Item | What they bring (for example) | Why the bank wants it |
|---|---|---|
| Tax ID | EIN confirmation letter (IRS Form CP-575) | Ties the account to a federal tax identity |
| Formation | Articles of Organization filed with the state | Proves the LLC legally exists |
| Governance | Operating agreement listing both members at 50% each | Shows who can act on the account |
| Identity | Driver's license for each member | KYC and beneficial-ownership compliance |
| Ownership disclosure | Beneficial-ownership form for both 50% owners | Required federal Customer Due Diligence |
| Deposit | Opening deposit, for example $100 | Activates the account |
Because both members each own more than 25%, both must be disclosed and both may need to sign. Single-owner businesses simplify this to one person.
Online-only and neobank accounts: what changes
Digital business banks and fintech platforms have shortened the process, but the underlying requirements are the same — they are just verified electronically. Expect to upload photos of your ID and formation documents, enter your EIN, and answer beneficial-ownership questions in a form. What tends to differ:
- Faster identity checks — verification is automated, often approving in minutes rather than a branch visit.
- Eligibility limits — some online platforms do not serve certain entity types (multi-owner corporations, trusts, or cash-heavy businesses).
- Deposit method — funding by ACH transfer or debit card instead of walking in cash.
- FDIC coverage — many fintechs are not banks themselves and hold deposits through a partner bank. Confirm where your money actually sits.
The document list is identical; only the delivery is different.
Decision framework: choosing where to open
The right account depends on how your business handles money, not on which bank has the best sign-up offer.
A traditional brick-and-mortar bank works best when:
- You deposit physical cash or checks regularly (retail, food service, trades).
- You expect to seek a bank loan or line of credit later and want an established relationship.
- You value in-person help resolving disputes, wires, or fraud.
An online or neobank account works best when:
- Your revenue is card- and ACH-based with little physical cash.
- You want lower fees, no minimum balance, and fast setup.
- You run a lean, remote, or single-owner operation.
Avoid rushing the choice when: you have not yet decided your legal structure, your state registration is not final, or your business name and EIN do not match your filed documents. Opening on mismatched paperwork causes accounts to be frozen during review. Settle the formation first, then open.
Why the account you open is the record that funds you later
Here is what most guides skip. Your business checking account is not just a place to hold money — it is the primary evidence lenders read when you seek capital. Revenue-based and MCA-marketplace funders underwrite on your bank deposits and revenue rather than leaning on your credit score. They want to see consistent inflows, an average daily balance that does not swing negative, and a pattern of real business activity.
That means three habits from day one:
- Run all revenue through the business account. Deposits scattered across personal accounts are invisible to underwriters and weaken your application.
- Avoid frequent negative days and overdrafts. They are the single biggest red flag in a deposit-based review.
- Keep the account long enough to build history. Most revenue-based funders want to see several months of statements.
By the time you need working capital, this account decides your terms. For the full picture of how cash-flow lending works, see our guide to revenue-based business financing and how underwriters read business bank statements for funding.
Common mistakes that delay or freeze new accounts
From reviewing thousands of funding files, the same avoidable snags show up again and again:
- Name mismatch. The name on your EIN letter, your state filing, and your ID must align. A DBA that was never registered stops the process.
- Missing beneficial-owner details. If a co-owner cannot be present or provide ID, the account often cannot open.
- Using a personal account for business. It pierces your liability protection and makes future funding far harder to document.
- No operating agreement or resolution. LLCs and corporations are frequently sent home to produce one.
- Applying before the state approves your formation. Banks verify against live state records; a pending filing means a pending account.
Solve these before you apply and a business account is genuinely a same-day task.
Frequently asked questions
Can I open a business bank account without an EIN?
Sometimes. A sole proprietor with no employees can often open one using their Social Security number. But an LLC, corporation, or partnership needs an EIN, and even sole proprietors benefit from one because it separates business and personal finances and looks more established to future lenders. An EIN is free and takes minutes to get from the IRS website.
How much money do I need to open a business account?
Opening deposits are usually small, commonly $25 to $100, and some online business accounts require nothing at all. Watch instead for minimum-balance requirements that trigger monthly fees if your balance drops below a threshold. For a new business managing cash flow, a no-minimum account is often the safer choice.
Do all owners need to be present to open the account?
Federal beneficial-ownership rules require identifying everyone who owns 25% or more of the business plus one person who controls it. Many banks require those owners to be present or to sign, though some allow remote verification. If a co-owner cannot attend, call ahead and ask how the bank handles it before you go.
What is the difference between an EIN letter and my formation documents?
They serve different purposes. Your EIN confirmation letter (IRS Form CP-575) proves your federal tax identity. Your formation documents — Articles of Organization for an LLC or Articles of Incorporation for a corporation — prove your business legally exists at the state level. Banks typically want both.
Can I open a business account online?
Yes. Online business banks and many traditional banks let you open an account digitally by uploading your ID and formation documents, entering your EIN, and completing beneficial-ownership questions. The requirements are identical to a branch; only the verification is electronic. Confirm the platform is FDIC-insured or holds deposits through an insured partner bank.
Why does my business bank account matter for getting funding later?
Because revenue-based and MCA-marketplace lenders approve on your bank deposits and revenue rather than credit score alone. Your business checking account is the record they underwrite — they look at consistent deposits, average daily balance, and whether the account runs negative. Running all revenue through one dedicated business account from the start makes you far easier to fund.
Do I need a business license to open the account?
Not usually for the account itself, but some banks ask for one if your industry or locality requires licensing (contractors, food service, certain professional services). It varies by city and county. If your business needs a license to operate legally, bring it — it can only help.
What can I do if my business is brand new with no revenue history?
You can still open the account with your formation documents, EIN, and ID — no revenue is required to open. The important step is to route every dollar of income through it from day one. When you later seek working capital, revenue-based funders typically look for a few months of deposit history, a minimum of roughly $10,000 in monthly revenue, and will consider owners with FICO scores of 500 and up, with decisions often in 24 to 48 hours. No responsible funder guarantees approval, but a clean, active account is what puts you in position.
