The documents and information a bank will ask for

Most banks will ask for the same core set of documents before they open a business account. You'll need proof of your business's legal structure, proof of your identity, and proof that you have authority to open the account on behalf of the business. The exact documents vary slightly by bank and by what type of business you run, but the pattern is consistent enough that you can prepare everything before you walk in or start an process online.

The bank needs to verify that your business actually exists and that you are who you say you are. This protects them from fraud and satisfies federal anti-money-laundering rules. It also protects you—a bank that skips these steps is a bank that may freeze your account later when they finally do the verification.

Key Takeaways

  • You will need a government-issued ID, proof of your business structure (articles of incorporation, EIN letter, or DBA registration), and documentation showing you have signing authority.
  • The bank will verify your identity against federal databases and may ask follow-up questions about the source of your deposits or the nature of your business.
  • Most banks require an initial deposit to open the account, ranging from $0 to $500 depending on the institution and account type.
  • The entire process typically takes one to five business days once you submit all documents, though some banks offer same-day opening for online applications.
  • If you are a sole proprietor without an EIN, you can use your Social Security number, but registering for an EIN first makes the account setup clearer.

Documents you need for sole proprietorships

If you operate as a sole proprietor, the bank needs less paperwork than it would for a corporation or LLC. You'll need a government-issued photo ID (driver's license, passport, or state ID card), your Social Security number, and proof of your business name if you operate under a name different from your own.

Proof of your business name can be a DBA (Doing Business As) certificate filed with your county or state, or a business license. If you have already obtained an Employer Identification Number (EIN) from the IRS, bring the letter the IRS sent you confirming it. If you haven't, the bank can still open the account using your Social Security number, though having an EIN makes the process smoother and keeps your personal and business finances more clearly separated.

The bank will also ask what your business does and may ask for documentation of that activity—a contract with a client, an invoice you've issued, or a business license. They're not trying to be difficult; they're verifying that the account is for a real business and not a front for something else.

Documents you need for LLCs and corporations

For an LLC or corporation, the bank will ask for your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation). These are the documents you filed with your state to create the business legally. You'll also need the EIN letter from the IRS and a government-issued ID for the person opening the account.

Many banks also ask for a resolution or certificate of authority showing that you have the power to open and manage the account. This is a document signed by the other owners or the board of directors stating that you are authorized to act on behalf of the business. Some banks provide a template; others accept a straightforward letter from the business stating who has signing authority. If you are the sole owner, this step is often skipped, but call ahead to ask.

Bring your EIN letter—the actual letter from the IRS, not a screenshot or photocopy. Banks treat this as the official proof that your business exists and has a tax ID. If you've lost it, you can request a new one from the IRS online through their Business Services Online portal or by calling 800-829-4933.

What the bank will verify about you

Once you submit your documents, the bank runs your name and Social Security number through ChexSystems or Early Warning Services, databases that track banking history. They're looking for a pattern of fraud, unpaid overdrafts, or accounts closed due to suspicious activity. If you have a clean history, this check takes a few minutes. If there's a flag, the bank may ask you to explain it or may decline to open the account.

The bank will also verify your identity against government records—driver's license databases, the Social Security Administration, and sometimes other sources. This is automated for most applications and happens in the background. If something doesn't match (a name spelling difference, an old address still on file), the bank will contact you to clarify.

For the business itself, the bank verifies that your EIN is real and matches the business name you provided. They may also search public records to confirm that your LLC or corporation is in good standing with the state. If your business is newly formed, this verification may take longer because the state's records and the IRS's records don't always sync when ready.

Initial deposit requirements and account minimums

Most banks require an initial deposit to open a business account, though the amount varies widely. Some banks have no minimum; others require $100, $500, or more. A few banks waive the initial deposit if you set up direct deposit or maintain a certain monthly balance. Check the bank's website or call before you go in, because this can be a deciding factor if you're choosing between banks.

The initial deposit is not a fee—it's money that goes into your account and belongs to you. You can withdraw it when ready after the account opens if you want, though some banks require you to maintain a minimum balance to avoid monthly fees. Read the account terms carefully, because the difference between "no minimum balance" and "minimum balance of $500" can cost you money in fees if you don't maintain it.

Timeline and what happens after you submit

If you explore online, the bank typically verifies your identity and documents within one to three business days. If you go to a branch in person, the process can be faster—sometimes same-day—because the banker can verify your ID on the spot and ask follow-up questions when ready if something doesn't match.

Once the bank approves your process, they'll issue you a debit card and checks (if you request them), and your account will be active. You'll receive login credentials for online banking, usually via email or text. Some banks mail checks and debit cards, which can take five to seven business days; others offer expedited delivery for a small fee.

If the bank needs more information—a clearer copy of a document, clarification on the source of your deposits, or explanation of something in your banking history—they'll contact you. Respond quickly; delays in providing what they ask for can slow down the opening process by days or weeks.

What to do if the bank declines your process

Banks can decline a business account process for several reasons: a pattern of overdrafts or fraud in your personal banking history, an EIN that doesn't match the business name you provided, or a business that doesn't exist in state records yet. If this happens, ask the bank why. They're required to tell you, and the reason matters because it determines what you can fix.

If the issue is your personal banking history, you may have better luck with a bank that uses a different verification service or that has less strict policies—community banks and credit unions often have more flexibility than large national banks. If the issue is your business registration, make sure your LLC or corporation is actually filed and in good standing with your state before you try again. If the issue is a mismatch between your EIN and business name, contact the IRS to correct it before reapplying.

You can also try a different bank. There is no central record of declined applications, so explore at another bank does not hurt your chances. Each bank makes its own decision based on its own risk tolerance.

Frequently Asked Questions

Can I open a business account with just my Social Security number and no EIN?

Yes. If you are a sole proprietor, the bank can open the account using your Social Security number instead of an EIN. However, getting an EIN (which is free from the IRS) makes the process clearer and keeps your business finances more separate from your personal finances. You can obtain an EIN online at irs.gov in about 15 minutes.

What if my business is brand new and not yet registered with the state?

If you are a sole proprietor operating under your own name, you can open an account when ready with just your ID and Social Security number. If you are forming an LLC or corporation, you need to file your articles with the state first. This typically takes one to two weeks, though some states offer expedited filing for a fee. Once filed, you can open the account.

Do I need to bring original documents or are copies okay?

For in-person applications, bring originals so the banker can verify them against your ID. For online applications, you'll upload scans or photos. Banks typically ask for clear, legible images of both sides of documents. If the bank cannot read something, they'll ask you to resubmit.

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

Debit cards usually arrive within five to seven business days by mail, though some banks offer expedited delivery. Checks take longer—typically one to two weeks—because they are printed to order. If you need checks when ready, ask the bank if they offer temporary check stock or if you can order checks from a third-party printer.

What if I have a bad credit score or past banking problems?

Business accounts are not based on credit score, so a low personal credit score will not disqualify you. However, if you have a history of overdrafts, fraud, or accounts closed due to suspicious activity, some banks may decline. Try community banks or credit unions, which often have more flexible policies, or ask the declining bank specifically what would need to change for you to reapply.
