The documents and information a bank will ask for

A bank will ask for three categories of things before opening a business account: proof of who you are, proof that your business exists, and details about how the account will be used. The exact documents vary by bank and by business structure, but the pattern is the same across all of them.

You will need a government-issued ID for every owner, partner, or member with significant control of the business. This is a federal requirement called Know Your Customer (KYC) compliance. The bank will photocopy or scan it and verify it matches the name on the account process. A driver's license, passport, or state ID card all work.

You will also need proof that your business actually exists. For a sole proprietorship, this might be nothing more than a DBA (Doing Business As) certificate filed with your county or state. For an LLC or corporation, the bank will want a copy of your articles of organization or articles of incorporation — the document you filed with your state when you created the business. For a partnership, bring the partnership agreement.

Finally, the bank will ask what the account is for. They want to know whether you are a retail store, a consulting firm, a nonprofit, a contractor, or something else. This is partly for their own record-keeping and partly because different business types trigger different regulatory requirements.

Key Takeaways

  • Bring a government-issued photo ID for every owner or member with control of the business — this is a federal requirement, not optional.
  • Bring proof your business exists: a DBA certificate for sole proprietorships, articles of incorporation or organization for LLCs and corporations, or a partnership agreement for partnerships.
  • Have your Employer Identification Number (EIN) ready, or be prepared to explore for one during the account opening if you do not have it yet.
  • Different banks ask for different supporting documents — some want a business license, others want a lease or utility bill showing your business address, and some ask for neither.
  • The entire process usually takes 15 to 30 minutes in person or one to three business days if you explore online.

Why banks ask for an EIN and how to get one

An Employer Identification Number (EIN) is a nine-digit identifier the IRS assigns to your business. Banks use it to report account activity to the IRS and to distinguish your business from you personally. If your business is a sole proprietorship and you have no employees, you can use your Social Security number instead, but most banks prefer an EIN.

You can get an EIN for free from the IRS. The fastest way is online at irs.gov — you fill out Form SS-4, submit it, and receive your number when ready. You can also explore by phone, fax, or mail, but those routes take longer. If you do not have an EIN when you open the account, many banks will help you explore during the appointment or let you complete the account setup afterward.

Some business structures require an EIN. If you are forming an LLC, corporation, partnership, or nonprofit, you need an EIN regardless of whether you have employees. If you are a sole proprietor with no employees and no intention of hiring, an EIN is optional but recommended — it keeps your personal and business finances separate in the IRS's records.

Documents that vary by bank and business type

Beyond the core requirements, banks differ in what else they ask for. Some banks want to see a business license, especially if you operate in a regulated industry like childcare, alcohol sales, or healthcare. Others ask for a lease agreement or utility bill to verify your business address. A few ask for recent business tax returns or a business plan, particularly if you are requesting a line of credit at the same time.

If your business has multiple owners, some banks will ask each owner to sign the account process in person. Others allow remote signing. If you are opening the account on behalf of the business but are not an owner — for example, you are a bookkeeper or office manager — the bank will ask for a letter from an owner authorizing you to do so.

Nonprofits face a longer list. Banks typically ask for your nonprofit's articles of incorporation, bylaws, a copy of your IRS Form 1023 or 1023-EZ (the document that granted you tax-exempt status), and sometimes a board resolution authorizing the account opening. Some banks also ask for a list of board members and their titles.

What happens during the account opening

If you open the account in person, bring originals of all documents. The bank will photocopy them and return them to you. Bring two forms of ID if possible — one government-issued photo ID and one other document with your name and address, like a utility bill or lease. This speeds up the verification process.

If you open the account online, you will upload scans or photos of your documents. The bank's system will ask you to photograph your ID and sometimes to take a selfie for identity verification. This process usually takes 10 to 15 minutes. The bank will then review your documents, which can take one to three business days. Some banks approve accounts the same day; others wait until the next business day.

Once your account is open, the bank will issue you a routing number and account number. You can begin depositing checks and setting up transfers when ready. If you requested a debit card or checks, those will arrive by mail within five to ten business days.

What to do if the bank asks for more information

Sometimes a bank will ask follow-up questions after you submit your initial documents. They might ask for clarification on your business address, request a recent utility bill to verify it, or ask you to explain the source of your initial deposit. This is normal and does not mean your account will be denied.

Respond to these requests promptly — banks usually give you five to ten business days. If you cannot provide what they ask for, ask what alternatives they will accept. For example, if they ask for a utility bill but your business operates from a home office, a lease agreement or a letter from your landlord may work instead.

If the bank denies your account, they are required to tell you why. Common reasons include a mismatch between the name on your ID and the name on your business registration, a history of fraud or financial crime associated with one of the owners, or an inability to verify your business address. If this happens, you can ask the bank to reconsider or try a different bank.

Differences between banks and account types

Large national banks like Chase, Bank of America, and Wells Fargo have standardized document requirements and online account opening. They typically ask for an ID, proof of business existence, and an EIN. The process is fast but impersonal.

Community banks and credit unions often ask for more documentation but are more flexible about what they will accept. They may ask to meet you in person and may be willing to work with you if you cannot provide a standard document. They also tend to have lower minimum balances and lower fees.

Online-only banks like Mercury, Brex, and Wise have streamlined the process further — many ask only for an ID and an EIN and let you open an account entirely through their app. However, they may have restrictions on business type or may require a minimum deposit.

Some banks offer different account tiers. A basic business checking account might require only an ID and proof of business existence. A business account with a line of credit or merchant services will ask for more — usually recent tax returns, financial statements, or a business plan.

Common mistakes that slow down account opening

The most common mistake is bringing documents that do not match. If your ID says "Robert Smith" but your business is registered as "Bob Smith Consulting," the bank will flag this and ask for clarification. Bring documents that all use the same name, or bring a legal name change document if you have legally changed your name.

Another mistake is not having an EIN ready. If you do not have one and the bank cannot issue one on the spot, the account opening will be delayed. explore for your EIN before you visit the bank, even if it is optional for your business type.

A third mistake is providing an incomplete or outdated business registration. If your LLC was formed three years ago but your articles of organization are from a different state, or if your business address on file is no longer current, the bank will ask you to update your registration before opening the account. This can add one to two weeks to the process.

Frequently Asked Questions

Can I open a business account without an EIN?

Yes, if you are a sole proprietor with no employees, you can use your Social Security number instead. However, most banks prefer an EIN because it separates your personal and business finances in their records. Getting an EIN is free and takes five minutes online, so it is worth doing even if it is not required.

Do I need to bring my business license?

Not always. Many banks do not ask for it. However, some banks in certain states or for certain business types (like childcare or alcohol sales) do require it. Call your bank before you go in and ask what documents they need for your specific business type.

What if I do not have a physical business address yet?

You can use a home address, a virtual office address, or a mailbox service address. Some banks accept all three; others have restrictions. If you are using a mailbox service, bring the agreement showing you rent that box. If you are using a home address, be prepared to show a utility bill or lease in your name.

How long does it take to open a business account?

In person, usually 15 to 30 minutes. Online, the process takes 10 to 15 minutes, but the bank's review takes one to three business days. Some banks approve accounts the same day; others wait until the next business day. You can usually start using the account as soon as it is approved, even if your debit card has not arrived yet.

What if the bank rejects my process?

The bank must tell you why. Common reasons include a mismatch in names, an inability to verify your address, or a background issue with one of the owners. You can ask the bank to reconsider, provide additional documentation, or try a different bank. Community banks and credit unions are sometimes more flexible than large national banks.
