What documents and information you'll need before you walk in

Most banks want the same core set of documents: your business registration paperwork, a form of ID, your Social Security number or EIN, and proof of your business address. The exact list depends on your business structure — sole proprietorship, LLC, corporation, partnership — and which bank you choose. Some banks add extra requirements like a minimum opening deposit or proof of business income.

The fastest path is to call the bank's business services line before you go in. Tell them your business structure and ask for their specific checklist. Banks update their requirements regularly, and what one branch needs may differ slightly from another. A five-minute phone call saves you a wasted trip.

Key Takeaways

  • You will need government-issued ID, your Social Security number or EIN, and proof of your business address — usually a utility bill or lease.
  • Your business registration documents (articles of incorporation, LLC formation papers, or DBA filing) are required; banks will not open an account without proof the business legally exists.
  • Some banks require a minimum opening deposit, which ranges from zero to several thousand dollars depending on the account type and the bank.
  • Sole proprietors can often open an account with just a Social Security number, but an EIN makes the process smoother and keeps personal and business finances separate.
  • Call ahead to confirm the exact list — requirements vary by bank, account type, and whether you are opening in person or online.

Documents that prove your business exists

Banks need to see that your business is real and legally registered. What counts depends on your structure. If you formed an LLC or corporation, bring your articles of incorporation or articles of organization — the document the state issued when you registered. If you filed a DBA (doing business as), bring that filing receipt or certificate. If you are a sole proprietor, you may not have formal registration paperwork, and the bank will usually accept your Social Security number as proof.

Get copies of these documents before you go. If you registered with your state recently, you can read them from your state's Secretary of State website or the agency that handles business filings in your state. If you do not have them yet, order them now — they can take one to two weeks to arrive by mail, though many states offer expedited digital copies for a small fee.

Identification and tax information

Bring a government-issued photo ID — a driver's license, passport, or state ID card. The bank will verify your name and address against it. You will also need to provide your Social Security number or your business's EIN (Employer Identification Number). If you are a sole proprietor with no employees, you can use your Social Security number. If you have employees or want to keep your personal and business finances completely separate, you will need an EIN, which you can get free from the IRS.

If you do not have an EIN yet, you can request one online at the IRS website — it takes about 15 minutes and you get a number when ready. Print the confirmation page. Some banks will let you open an account with the confirmation number and explore for the EIN later, but calling ahead to ask saves confusion.

Proof of your business address

Banks need to verify where your business operates. If you have a physical office or storefront, bring a utility bill, lease agreement, or property tax statement showing your name and the business address. If you work from home, a recent utility bill with your home address usually works. If you use a mail forwarding service or a virtual office address, bring the agreement showing you have the right to use that address.

The document needs to be recent — usually within the last 60 to 90 days. If your address is brand new and you do not have a utility bill yet, a signed lease or a letter from your landlord confirming the address can work instead. Ask the bank what they will accept before you gather documents.

Minimum deposit requirements and account fees

Some banks require you to deposit money when you open the account. This ranges from zero to several thousand dollars depending on the bank and the account type. A basic business checking account might have no minimum, while a premium account with higher transaction limits or added services might require $1,000 or more. Online banks tend to have lower or no minimums; traditional banks vary widely.

Ask about monthly fees, per-transaction charges, and what happens if your balance drops below a certain level. Some banks waive monthly fees if you maintain a minimum balance or set up direct deposit. Others charge a flat monthly fee regardless. The fee structure matters more than the opening deposit — a $500 opening deposit with a $25 monthly fee costs you more over time than a $0 opening deposit with a $10 monthly fee.

Additional documents for partnerships and corporations

If your business has more than one owner, the bank may ask for additional paperwork. Partnerships usually need a copy of the partnership agreement or the DBA filing. Corporations need the articles of incorporation and sometimes a corporate resolution authorizing the account opening — a document signed by the board saying the account is approved. LLCs typically need the articles of organization and sometimes an operating agreement.

If you are opening the account as a representative of the business rather than as the owner, bring a document showing you have authority to do so — a power of attorney, a board resolution, or a letter from the owner. Some banks ask for this even if you are the owner, to confirm you are not opening the account fraudulently.

Opening the account in person versus online

In-person accounts usually require all documents at the time you open. Online accounts sometimes let you upload documents or provide them later, but the bank will not set up the account until they verify everything. The timeline is similar either way — a few days to a week for the account to be fully set up and ready to use.

Online accounts are faster if you have all documents ready and can upload them clearly. In-person accounts let you ask questions on the spot and walk out with a debit card the same day at some banks. If you have questions about what counts as proof of address or whether your business structure needs extra paperwork, the in-person route gives you a chance to ask before you submit anything.

Frequently Asked Questions

Can I open a business account with just my Social Security number?

Yes, if you are a sole proprietor with no formal business registration. The bank will use your Social Security number as your tax ID. However, getting an EIN from the IRS (free and takes 15 minutes online) makes the process smoother and keeps your personal and business finances clearer on paper.

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

You can use a home address, a mail forwarding service address, or a virtual office address. Bring proof you have the right to use that address — a lease, utility bill, or service agreement. Some banks are stricter about virtual addresses; call ahead to confirm they will accept it.

Do I need to bring my business plan or financial statements?

Not for opening the account. Banks need proof the business exists and your identity, but they do not require a business plan or income history. Some banks may ask about your business type or expected monthly volume, but this is for their records, not to decide whether to open the account.

How long does it take to open a business account?

In person, you can usually finish in 30 minutes to an hour. Online, it takes 10 to 15 minutes to submit, but the bank needs one to five business days to verify your documents and set up the account. You can usually start using the account (transfers, bill pay) before the debit card arrives.

What if the bank rejects my documents?

The bank will tell you what is missing or unclear. Common issues are documents that are too old, proof of address that does not match your ID, or business registration paperwork that does not match the name you provided. Ask the bank what they need instead, get it, and resubmit. This usually takes a few days.
