The documents and information a bank will ask for before opening an account

To open a business bank account, you will need to bring proof of your business structure, a government-issued ID, and your tax identification number. The exact documents depend on whether you are a sole proprietor, partnership, LLC, corporation, or other entity — and they vary slightly between banks. Most banks will also ask for a business address, expected monthly deposit volume, and the names of anyone who will have signing authority on the account.

The process usually takes one to three business days if you have all documents ready. Some banks offer same-day opening for online applications, though you may need to visit a branch in person to verify your identity and sign the signature card.

Key Takeaways

  • You will need your business structure documents (articles of incorporation, LLC formation papers, or a sole proprietor declaration), a government-issued photo ID, and your EIN or Social Security Number.
  • Banks require the names and IDs of all owners and anyone with signing authority, so gather those before you go in.
  • A business address, even if it is your home, is required — banks will not open accounts for businesses without a physical location.
  • Bring proof of your business name registration if you operate under a name different from your legal name.
  • Some banks charge monthly fees or require a minimum balance; compare these costs before choosing where to open your account.

Documents you need for each business structure

A sole proprietor needs a government-issued photo ID and either an EIN (Employer Identification Number) or permission to use a Social Security Number. If you registered your business name with your state or county, bring that registration document. If you operate under your legal name only, you may not need a registration at all.

An LLC or corporation must bring the articles of organization (for an LLC) or articles of incorporation (for a corporation), filed with your state. The bank will want to see the filing date and the state seal. You will also need an EIN, which you can obtain free from the IRS before opening the account. Bring the IRS letter confirming your EIN.

A partnership requires a partnership agreement signed by all partners, the EIN letter from the IRS, and government-issued IDs for each partner. Some banks also ask for a resolution authorizing the account, though this is less common.

A nonprofit organization will need articles of incorporation, a 501(c)(3) information letter from the IRS (or a copy of your application if you are still pending), and the EIN letter. The bank may also ask for board meeting minutes authorizing the account.

Identification and ownership information

Bring a current government-issued photo ID for yourself and for every owner of the business. A driver's license, passport, or state ID card all work. The bank will copy these and verify them against their fraud database.

If anyone other than the owners will have signing authority — such as a manager, accountant, or employee — the bank will ask for their name, date of birth, and government-issued ID as well. You do not have to add signers on day one; you can do this later. However, telling the bank upfront who will have access prevents delays when you need to add them.

The bank will also ask for the Social Security Number or EIN of each owner. This is used for tax reporting and fraud prevention. If your business is a sole proprietorship without an EIN, the bank will use your Social Security Number.

Business address and operational details

You must provide a physical business address. This can be your home, a commercial office, a virtual office service, or a mailbox service — but it cannot be a PO Box. The bank will verify that the address exists and may send mail there to confirm.

The bank will ask what your business does and what you expect your monthly deposit and withdrawal volume to be. These questions help them assess risk and determine which account type fits you best. Be honest about your estimates; if your actual volume is much higher later, the bank may reclassify your account or flag it for review.

Some banks ask whether you will be accepting credit card payments, checks, or cash deposits, and how many transactions you expect per month. This information helps them recommend the right fee structure and services.

What happens after you submit your documents

The bank will verify your documents with the state (for LLC and corporate filings) and the IRS (for your EIN). This verification usually takes one to three business days. During this time, the bank may contact you if any information is missing or unclear.

Once verification is complete, you will sign the signature card and account agreement. Some banks do this in person; others mail it or send it electronically. You will receive your account number, routing number, and debit card within one to two weeks. You can usually start depositing checks or making transfers before the debit card arrives.

If you opened the account online, the bank may require you to visit a branch within 30 days to verify your identity in person. Check the bank's policy before opening.

Fees and minimum balance requirements

Business checking accounts often have monthly maintenance fees ranging from zero to $25 or more, depending on the bank and account type. Some banks waive the fee if you maintain a minimum balance (often $1,000 to $5,000) or meet a monthly deposit threshold.

Compare the fee structure across at least two or three banks before opening. A bank with a $15 monthly fee costs $180 per year, which adds up quickly for a small business. Some online banks and credit unions offer business accounts with no monthly fee and no minimum balance.

Ask about fees for specific services you will use: wire transfers, ACH transfers, stop payments, and overdraft protection. These can range from $0 to $35 per transaction depending on the bank.

Timeline and next steps

Gather your documents before you visit the bank or start an online application. Make a checklist: business structure documents, government-issued IDs for all owners and signers, your EIN letter, your business address, and your expected transaction volume. Having everything ready cuts the opening time in half.

You can open an account in person at a branch or online through the bank's website. Online opening is usually faster, but some banks still require an in-person visit to verify identity. Call the bank or check their website to see which option they offer.

After opening, set up online banking and link your business account to your accounting software if you use one. This makes tracking income and expenses much easier.

Frequently Asked Questions

Can I open a business account without an EIN?

Yes, if you are a sole proprietor. You can use your Social Security Number instead. However, an EIN keeps your personal and business finances separate for tax purposes and is free to obtain from the IRS. Most banks recommend getting one even for sole proprietors.

Do I need to have my LLC or corporation officially registered before opening an account?

Yes. The bank will ask to see your articles of organization or incorporation filed with your state. You cannot open a business account for an LLC or corporation that does not yet exist legally. Sole proprietors can sometimes open accounts with just a business name registration, depending on the bank.

What if I do not have a physical office yet?

You can use your home address, a virtual office service address, or a mailbox service address. The bank needs a physical location to verify and send mail to — a PO Box will not work. If you move later, contact the bank to update your address.

How long does it take to get my debit card and checks?

Debit cards usually arrive within one to two weeks. Checks take longer — typically two to three weeks — because they are printed to order. You can start making deposits and transfers immediately after opening, even before your card arrives.

Can I add signers to my account after I open it?

Yes. You can add signers at any time by visiting the bank, calling, or using online banking, depending on the bank's policy. You will need to provide their name, date of birth, and government-issued ID. Some banks charge a small fee for adding signers.
