Documents and information you'll need before you walk in

Most banks want the same core set of documents from you before they'll open a business checking account. You'll need your Employer Identification Number (EIN) — the nine-digit tax ID the IRS assigns to your business. If you're a sole proprietor and haven't gotten an EIN yet, some banks will let you use your Social Security number instead, but getting an EIN takes about 15 minutes online at irs.gov and costs nothing.

Bring a government-issued photo ID — a driver's license or passport works. You'll also need proof that your business exists: a business license from your city or county, articles of incorporation if you're an LLC or corporation, or a DBA (Doing Business As) certificate if you're operating under a name different from your legal name. If you haven't filed these yet, you can often open the account while the paperwork is in progress, but the bank will want to see it within 30 days.

Have your business address ready — a physical street address, not a PO box. If you're running the business from home, use your home address. Some banks also ask for a business phone number, though a cell phone counts. If your business is brand new and you haven't chosen a bank yet, gather these documents first; it takes an hour or two and removes the friction when you're ready to sit down with a banker.

Key Takeaways

  • You need an EIN (or your Social Security number if you're a sole proprietor), a government photo ID, and proof your business exists — like a business license or articles of incorporation.
  • Banks require a physical street address for the business, not a PO box, and will ask for a business phone number (a cell phone is fine).
  • If your business paperwork isn't filed yet, most banks will open the account while you're getting it done, but will want to see it within 30 days.
  • Different account types — sole proprietor, LLC, S-corp, C-corp — may require slightly different paperwork, so call the bank first if you're unsure which documents apply to you.
  • Bring originals or certified copies of licenses and incorporation documents; banks won't accept photos or scans for the initial opening.

What changes depending on your business structure

A sole proprietorship is the simplest route. You can open an account with just your Social Security number and a business license, though an EIN makes the process smoother. No corporate paperwork required.

An LLC needs articles of incorporation filed with your state and an EIN. Bring both. Some banks also ask for an operating agreement — the internal document that outlines how your LLC is run — though they don't always require it for account opening. Call ahead and ask.

An S-corp or C-corp requires articles of incorporation, an EIN, and sometimes a corporate resolution — a document signed by the board authorizing someone to open the account. Not every bank asks for this, but larger institutions often do. If your bank requests it and you don't have one, the bank can usually provide a template.

A partnership needs articles of partnership (or a partnership agreement) and an EIN. Some banks ask for a resolution naming which partners can sign checks and withdraw money.

How to verify what your specific bank needs

Banks vary in what they require, so don't assume one bank's list matches another's. Call the business banking department at the bank where you want to open the account and ask for their specific checklist. Most banks have a one-page document they'll email or mail to you listing exactly what to bring.

If you're opening online rather than in person, the bank will ask you to upload images of your documents — usually a photo of your ID, a photo of your EIN letter, and a photo of your business license or articles of incorporation. Make sure the images are clear and show all four corners of the document. If a corner is cut off, the bank will reject it and ask you to resubmit.

Some online banks move faster than brick-and-mortar branches. They may open your account the same day you submit documents, or within one business day. In-person openings usually take 15 to 30 minutes, and the account is live by the end of the day or the next morning.

Ownership and signatory information the bank will ask for

The bank needs to know who owns the business and who is authorized to sign checks and move money. For a sole proprietorship, that's you. For an LLC, partnership, or corporation, you'll list all owners and specify which ones can sign on the account.

You don't have to list every owner as a signer. Many businesses have one or two people authorized to sign checks while other owners have no account access. The bank will ask you to decide this upfront. If you change your mind later, you can update signers by submitting a written request, though some banks charge a small fee for the change.

If someone other than the owner will be signing checks — a manager, accountant, or bookkeeper — the bank will need their name, date of birth, and government ID. They may also need to come in person or verify their identity online, depending on the bank's policy.

Initial deposit requirements and account minimums

Most banks require an opening deposit to activate the account. This is usually between $25 and $500, depending on the bank and the account type. Some banks waive the opening deposit if you set up direct deposit or maintain a minimum balance.

After the account opens, many business checking accounts have a monthly minimum balance — often $500 to $2,500 — to avoid a monthly fee. If your balance drops below the minimum, you'll pay a fee that ranges from $5 to $25 per month. Some banks waive the fee if you maintain a certain number of debit card transactions per month or set up automatic transfers.

Read the fee schedule before you open the account. The fee structure varies widely, and choosing an account with fees you can avoid will save you money over time.

What happens after you submit your documents

Once you've provided all documents, the bank verifies them — checking that your EIN is real, that your business license is current, and that your ID is valid. This verification usually takes one to three business days. During this time, your account is typically open and you can deposit checks, but you may not be able to write checks or make transfers until verification is complete.

If the bank finds a problem — a document is expired, an image is unclear, or information doesn't match — they'll contact you and ask you to resubmit or provide additional paperwork. This can add a few days to the process.

Once verification is done, the bank will issue you checks, a debit card, and online banking access. Checks usually arrive in the mail within 5 to 10 business days. Debit cards may arrive at the same time or take longer, depending on the bank. Online banking access is typically available immediately after verification.

Common reasons banks reject or delay account openings

Banks sometimes flag accounts for additional review. The most common reasons are a mismatch between the name on your ID and the business name, an EIN that doesn't match your business structure (for example, an EIN registered to a different person), or a business license that's expired or not yet active.

If your business is very new — less than a month old — some banks may ask for additional documentation to confirm it's legitimate. This might include a lease, utility bill, or business plan. If you're opening an account for a business that operates in a regulated industry (cannabis, alcohol, firearms, gambling), expect a longer review and possibly a denial if the bank doesn't work with that industry.

Banks also review accounts if the owner has a history of fraud, money laundering, or other financial crimes. If your account is denied, the bank must tell you why in writing. You can then address the issue — get an expired license renewed, correct information in the system, or provide additional documentation — and reapply.

Frequently Asked Questions

Can I open a business checking account if I don't have an EIN yet?

Yes. Sole proprietors can use their Social Security number instead of an EIN. If you're an LLC, S-corp, or C-corp, you'll need an EIN before opening the account. Getting an EIN takes 15 minutes online at irs.gov and is free. The IRS issues it immediately, and you can use it right away.

Do I need to bring original documents or can I send copies?

For in-person openings, bring originals or certified copies. Banks won't accept photocopies or photos for the initial opening. For online openings, upload clear photos of both sides of each document. Make sure all four corners are visible and the text is readable.

What if my business address is my home?

That's fine. Use your home address as the business address. Banks understand that many small businesses operate from home. You don't need a separate commercial space or office to open a business checking account.

How long does it take to open a business checking account?

In-person openings usually take 15 to 30 minutes, and the account is live by end of day or the next morning. Online openings can be faster — sometimes same-day — but verification of documents typically takes one to three business days before you can write checks or make transfers.

What if the bank asks for documents I don't have?

Call the bank and ask what documents you can substitute. For example, if they ask for articles of incorporation and you haven't filed yet, ask if a DBA certificate or business license will work temporarily while you file the incorporation. Most banks are flexible if you explain your situation and commit to providing the missing document within 30 days.
