What banks ask for before they open your account
Most banks want the same core set of documents before they'll open a business checking account: proof of your business structure, a form of ID, and proof of your address. The exact list depends on whether you're a sole proprietor, partnership, LLC, or corporation—and whether the bank knows you already. Some banks will let you start online; others require an in-person visit. A few ask for more if your business is new or if you're opening the account remotely.
The documents themselves are straightforward, but getting them in the right order saves time. Banks check these documents against their fraud and money-laundering databases, so they're looking for consistency—the name on your ID should match the name on your business registration, and your address should be current. If something doesn't line up, the bank will ask you to clarify or bring different paperwork.
Key Takeaways
- Every business checking account requires a government-issued ID, proof of your business structure (EIN letter, articles of incorporation, or DBA filing), and a current address.
- Sole proprietors often need only an EIN letter from the IRS or a DBA filing from their state; LLCs and corporations need articles of organization or incorporation.
- Banks verify your identity against fraud databases, so your ID name, business name, and address must match across all documents.
- Some banks let you open online; others require you to visit in person, especially if you're new to that bank or opening a corporate account.
- The whole process usually takes one business day if you have all documents ready, or up to a week if the bank needs to verify your business registration with the state.
Documents you'll need by business structure
Sole proprietors typically need the least paperwork. Bring a government-issued ID (driver's license, passport, or state ID), proof of address (a utility bill or lease dated within the last 60 days), and either an EIN letter from the IRS or a DBA (Doing Business As) certificate from your state. If you're operating under your own name and have an EIN, the IRS letter is usually enough. If you're using a business name, you'll need the DBA filing.
Partnerships need a partnership agreement (even a straightforward one), an EIN letter, and IDs for all partners who will sign checks or access the account. Some banks ask for a resolution from the partnership authorizing the account, though this is less common. Each partner typically needs to provide their own ID and address proof.
LLCs need the articles of organization filed with your state, an EIN letter, and the ID and address proof of the person opening the account. If the LLC has multiple members, the bank may ask for a resolution or operating agreement showing who is authorized to open and manage the account. Some banks want this even if only one member is signing.
Corporations need the articles of incorporation, an EIN letter, and a corporate resolution authorizing the account. The resolution should name the person opening the account and specify who can sign checks. You'll also need the ID and address proof of that person. Banks are more cautious with corporate accounts because the liability structure is different, so they verify more carefully.
How to get the documents you don't have yet
If you don't have an EIN, you can get one free from the IRS in minutes. Go to irs.gov, search for "explore for an EIN online," and complete the form. You'll receive your EIN when ready and can print a confirmation letter right away. If you applied by phone or mail, the IRS will send the letter by post, which takes about two weeks. Most banks accept the printed confirmation as proof of your EIN.
If you need a DBA filing, contact your state's Secretary of State office or county clerk—it depends on your state. Some states file DBAs at the state level; others require county filing. The cost ranges from $10 to $100, and processing takes anywhere from same-day to two weeks depending on whether you file online or by mail. Once approved, you'll receive a certificate or filing confirmation that the bank will accept.
If you haven't filed articles of organization or incorporation yet, you'll need to do that before opening a business account. This is a state-level filing that formally creates your LLC or corporation. You can file online through your state's Secretary of State website or use a service like the Secretary of State's own filing system. The cost is usually $50 to $300, and processing takes one to five business days. Once filed, you'll receive a certificate of formation or incorporation that serves as proof.
For corporate resolutions, you don't need a lawyer. A straightforward one-page document stating that the corporation authorizes [your name] to open a business checking account and sign checks is enough. Some banks provide a template; others accept a handwritten version as long as it's dated and signed by an authorized officer. If your corporation has a board, the resolution should come from a board meeting, but for small corporations, a written statement from the owner usually works.
What happens during the verification process
Once you hand over your documents, the bank runs your ID through fraud and identity-verification databases. This usually takes a few minutes in-person or a few hours online. The bank also checks your business name against state records to confirm your EIN, DBA, or articles of organization are real and current. If everything matches, you'll be approved the same day.
If something doesn't match—your ID name differs from your business name, your address is outdated, or the bank can't find your business registration in the state database—the bank will ask for clarification. This might mean bringing additional documents, updating your address, or waiting while the bank contacts the state to verify your filing. This step can add a few days to the process.
Banks also check whether you or your business has a history of fraud, unpaid debts, or suspicious activity. They use systems like ChexSystems (for banking history) and OFAC (for sanctions and money-laundering concerns). If a flag comes up, the bank will either ask you to explain it or deny the account. Most flags are cleared quickly with a straightforward explanation.
In-person versus online account opening
Many banks now let you open a business checking account online, but the process varies. Some banks let you upload documents directly; others ask you to mail them in. Online opening usually takes longer—one to three business days—because the bank can't verify your ID in real time. You may also need to make a small deposit (usually $25 to $100) to set up the account, and some banks won't issue checks or a debit card until they've verified everything.
In-person opening is faster if you have all your documents. The bank verifies your ID on the spot, scans your business documents, and can often open the account the same day. You'll walk out with temporary checks or a debit card, and the account is usually active within 24 hours. The downside is that you have to visit a branch during business hours, and some banks require an appointment.
If you're opening an account at a bank where you don't already have a personal account, some banks require an in-person visit regardless. Others let you open online if you're willing to wait longer for verification. Call the bank's business banking line before you go to ask what they need and whether you can do it online.
Common reasons banks reject or delay accounts
The most common reason for delay is a mismatch between your ID and your business documents. If your driver's license says "John Smith" but your LLC is registered as "John R. Smith," the bank will flag it and ask for clarification. This is easily fixed with a letter from the state confirming the registration, or by updating your ID.
A second common issue is an outdated address. If your ID shows an old address and your business registration shows a new one, the bank can't verify which is current. Bring a recent utility bill, lease, or mortgage statement dated within the last 60 days to prove your current address.
Banks also sometimes can't find your business registration in the state database right away, especially if you filed very recently. The state's records may take a few days to appear in the bank's verification system. If this happens, ask the bank how long they'll wait before denying the account, and contact the state to confirm your filing was processed.
Finally, if you or your business has a history of fraud, unpaid debts, or involvement in money-laundering investigations, the bank may deny the account. This is rare for legitimate small businesses, but if it happens, you have the right to ask why and to dispute the decision if you believe it's wrong.
What to bring to avoid delays
Bring originals or certified copies of everything, not photocopies. Banks need to see the actual document to verify the seal, signature, or official stamp. For state filings like articles of incorporation or DBA certificates, bring the official document from the state, not a copy you printed from the state website. If you only have a printed copy, call ahead and ask if the bank will accept it—some will, others won't.
Bring two forms of ID if possible: your driver's license plus a passport or state ID. This speeds up verification. Bring proof of your current address even if it's on your ID—a recent utility bill, lease, or bank statement works. Bring your EIN letter or a printed confirmation from irs.gov. If you have a corporate resolution or partnership agreement, bring the original or a certified copy.
If you're opening the account online, scan documents in color and make sure text is legible. Banks reject blurry scans and ask you to resubmit. Save files as PDFs if possible, and name them clearly (e.g., "Articles_of_Organization.pdf" rather than "Document1.pdf"). This helps the bank's document team process your process faster.
Frequently Asked Questions
Can I open a business checking account if my business isn't registered yet?
No. Banks require proof that your business structure exists—an EIN letter for a sole proprietor, a DBA filing, or articles of organization for an LLC or corporation. You need to register your business first, which takes a few days to a week depending on your state. Once you have the registration, you can open the account.
Do I need to bring the original articles of incorporation or will a copy work?
Banks prefer originals or certified copies from the state. If you only have a photocopy or a printed version from your state's website, call the bank first and ask. Some banks accept printed copies; others require the official document. If they won't accept a copy, you can request a certified copy from your state's Secretary of State office for a small fee, usually $5 to $15.
What if my business name is slightly different on different documents?
Tell the bank before you explore. Small differences (like "John's Plumbing" versus "John's Plumbing LLC") are usually fine as long as they're consistent with your state registration. Bigger differences (like a completely different name) will cause the bank to flag the account. Contact your state to confirm what name is officially registered, and bring that confirmation to the bank.
How long does it actually take to open the account once I submit everything?
If you open in person with all documents ready, the account is usually active the same day or within 24 hours. If you open online, expect one to three business days for the bank to verify your documents and set up the account. If the bank needs to verify your business registration with the state, add another two to five business days. Weekends and holidays extend the timeline.
What if the bank denies my account?
The bank must tell you why. Common reasons are fraud history, unpaid debts, or inability to verify your identity or business registration. If you believe the denial is wrong, ask the bank for details and request a review. You can also try a different bank—different banks have different risk standards, and one may open an account that another rejected. If the issue is a fraud flag, contact the credit bureau or verification service to dispute it.
