What Documents Do You Need to Open a Business Checking Account?
Two forms of ID for every owner with 25% or more. Not just you — federal rules make the bank collect details on every beneficial owner, and this is the item that turns a twenty-minute appointment into a second visit.
Your formation documents and EIN letter. Articles of organisation from the state, the EIN confirmation notice, and an operating agreement if you have one.
Names that match exactly, everywhere. Most rejections are not missing documents. They are the same business name written three slightly different ways.
Opening a business account is administratively dull and rarely difficult, but it fails often enough to be worth preparing for. The failures cluster around three things: a missing owner, a missing document, and a name that does not match. Here is what to gather.
Proof the business exists
The bank needs a document issued by a government body, not by you. Which one depends on your structure:
- LLC — articles of organisation, filed with and stamped by your state. Some states call these a certificate of formation.
- Corporation — articles of incorporation, plus a corporate resolution naming who is authorised to open accounts.
- Partnership — the partnership agreement, and a filed certificate if your state requires one.
- Sole proprietor — usually nothing is filed, so the bank falls back on a fictitious-name or DBA registration if you trade under a name other than your own.
Download a fresh copy from your state's business portal rather than digging out the original. Banks occasionally want one issued within the last 60 or 90 days, and a current download costs nothing.
The tax identification number
For anything other than a bare sole proprietorship, this means your EIN confirmation notice — the letter the IRS generates at the end of the application. Bring the document, not just the number written down; several banks will not proceed on a number alone.
Sole proprietors without an EIN can often open on a Social Security number, though policies vary and some banks decline it for anything trading under a business name.
Identification for every beneficial owner
This is the step that catches people out, so it is worth being precise. Under federal customer due-diligence rules, banks must identify and verify every individual who owns 25% or more of the business, plus one person who exercises significant control — a managing member, president or general partner.
For each of those people, the bank will typically want:
- a government-issued photo ID, usually a driving licence or passport
- date of birth and residential address
- Social Security number or, for non-US persons, a passport number and country of issue
Two practical consequences. If you have a co-founder at 50%, they need to be present or to have submitted their details in advance, and a surprising number of appointments end there. And if ownership sits behind a holding company, the bank works up the chain to the humans, which takes longer and sometimes requires an ownership diagram.
The operating agreement
Single-member LLCs are not required to have one in most states, and plenty do not. Banks still ask, because it is the document that says who is allowed to act for the business.
If you do not have one, a short document naming yourself as sole member and sole authorised signatory is usually enough. If there are two of you, this is the document that decides whether one member can move money alone — worth reading before you sign the account paperwork rather than after.
What else they may ask for
Beyond the core set, requests vary by bank and by what your business does:
- Business licence or professional licence — standard in regulated trades
- Proof of business address — a utility bill or lease; a residential address is fine for most home-based businesses, but a virtual mailbox is sometimes refused
- Expected activity — monthly deposit volume, whether you take cash, whether you send or receive international wires. Answer honestly; a mismatch between what you said and what the account does triggers a review later
- An opening deposit — many accounts require nothing, but some ask for $25 to $100 in the account on day one
The three mismatches that cause rejections
Missing paperwork gets you a second appointment. Mismatched paperwork gets you a decline, and the fix is slower.
The business name. It has to read identically on the state filing, the EIN letter and the application. “Smith Consulting LLC” and “Smith Consulting, L.L.C.” are two different names to an automated check. Copy the state filing exactly, punctuation included.
The responsible party. The person named on the EIN should be the person named as the controlling party on the account. If you formed the entity through a service that listed itself, this needs correcting with the IRS first.
The address. A registered-agent address on the state filing and a home address on the application is normal and fine, but the bank will ask you to explain it. Have the answer ready rather than improvising.
Who this is wrong for
If your entity is not yet registered, none of this applies yet — the state filing has to exist first. Setting up an LLC for a side hustle covers that step.
If you are testing an idea and have no entity, you may not need a business account at all yet. A separate personal account holds the line adequately at very small scale, though it does not carry the legal separation an entity account does.
Then choose the account
With the folder assembled, the choice is about fees and requirements rather than paperwork. Our comparison of business checking accounts for an LLC covers which charge nothing monthly and which quietly require a balance, and the side-hustle version does the same for smaller balances.
