The documents and information banks require before you can open an account
Most banks need the same core set of documents to open a business account: proof of your business structure, proof of your identity, and proof of your address. The exact list depends on whether you are a sole proprietor, partnership, LLC, S-corp, or C-corp — each structure requires different paperwork. You will also need an Employer Identification Number (EIN) from the IRS, even if you are a sole proprietor with no employees, because banks use it to verify your business exists.
The process typically takes one to three business days if you have all documents ready, though some banks offer same-day opening if you explore online and your information verifies when ready. If documents are missing or information does not match what the bank finds in their systems, the timeline extends to a week or longer.
Key Takeaways
- You will need an EIN from the IRS, a government-issued photo ID, and proof of your business structure — the specific documents vary by business type.
- Banks verify your identity and your business's legal existence before opening the account, which is why mismatches between your process and public records cause delays.
- Sole proprietors can often open accounts faster than corporations because they need fewer documents, but they still need an EIN separate from their Social Security number.
- Bring originals or certified copies of documents to an in-person appointment; online applications usually require you to upload images or e-sign documents.
What documents you need by business structure
Sole proprietors typically need: a government-issued photo ID (driver's license or passport), proof of address (utility bill or lease dated within the last 60 days), and an EIN. Some banks accept a Social Security number instead of an EIN for sole proprietors, but most now require an EIN to comply with anti-money-laundering rules. You will also need to bring the business name you plan to use — if it is different from your personal name, the bank may ask for a DBA (Doing Business As) certificate filed with your state or county.
Partnerships need: a Partnership Agreement (signed by all partners), government-issued photo IDs for all partners, proof of address for all partners, and an EIN. The bank will verify that all partners listed in the agreement match the people opening the account.
LLCs need: the Articles of Organization filed with your state, an EIN, government-issued photo IDs for all members (or at minimum the managing member), and proof of address for the person signing the account paperwork. Some banks also request an Operating Agreement, though it is not always required.
Corporations (S-corp or C-corp) need: the Articles of Incorporation filed with your state, corporate bylaws, a board resolution authorizing the account opening, an EIN, government-issued photo IDs for the authorized signers, and proof of address. The bank will verify that the person opening the account has authority to do so — this is why the board resolution matters.
How to get an EIN if you do not have one
An EIN is a nine-digit number issued by the IRS that identifies your business for tax purposes. You can obtain one free from the IRS website (irs.gov) by filling out Form SS-4 online, by phone, by fax, or by mail. The online method is fastest — you receive your EIN when ready after completing the form.
You do not need to have filed taxes or registered your business with the state to get an EIN. The IRS issues it based on the information you provide about your business structure, location, and the type of work you do. If you are a sole proprietor, you can use your Social Security number instead of an EIN, but banks increasingly require an EIN for all business accounts.
Identity verification and address proof requirements
Banks verify your identity using government-issued photo identification — a driver's license, passport, or state ID card. The name on the ID must match the name on the account process. If you have recently changed your name, bring both your old and new ID, or bring a marriage certificate or court order showing the name change.
Proof of address must be a document dated within the last 60 days showing your name and physical address. Utility bills, lease agreements, mortgage statements, and insurance bills all work. A bank statement from another institution also works. Post office boxes do not count as proof of address — banks need a physical street address.
If you are opening a business account but your business address is different from your personal address, bring proof of both. For the business address, a lease, utility bill in the business name, or a property tax statement works. If you work from home, a utility bill showing your home address is sufficient.
What happens during the verification process
After you submit your documents, the bank runs background checks and verifies that your business structure documents are real and current. They check your EIN against IRS records, your business name against state filings, and your identity against government databases. This process usually takes one to three business days.
If information does not match — for example, if your EIN does not match your business name in IRS records, or if your address does not match what the state has on file — the bank will contact you to clarify. Mismatches do not automatically disqualify you, but they do delay opening. Have copies of your state filings and EIN confirmation letter ready to send if the bank asks.
Some banks also run a credit check or check your history with ChexSystems (a banking history database). These checks do not prevent you from opening a business account the way they might for a personal account, but they inform the bank's decision about which account tier to offer you and what opening deposit is required.
In-person versus online account opening
Many banks now offer both options. In-person opening at a branch means you bring original documents, show your ID to a banker, and sign paperwork on the spot. The account often opens the same day or within one business day. You can ask questions in real time if the banker needs clarification on your documents.
Online opening means you upload images of your documents, e-sign the account agreement, and verify your identity through a video call or by answering security questions. This is faster if your documents are clear and your information verifies when ready — sometimes the account opens within hours. If the bank needs to follow up on a document or a verification issue, it takes longer because communication happens by email or phone.
Choose in-person opening if you have any uncertainty about your documents or your business structure. Choose online opening if your documents are clear, your information is straightforward, and you want to open the account quickly.
Common reasons banks delay or deny account opening
Mismatched information is the most common cause of delay. Your name on the process does not match your ID. Your business address does not match your state filing. Your EIN does not match your business name. Your proof of address is older than 60 days. Any of these triggers a follow-up, which adds days to the process.
Banks also deny accounts if they cannot verify your identity or your business's legal existence. This happens when you provide a fake or expired ID, when your business structure documents are not on file with the state, or when your EIN does not exist in IRS records. If this happens, contact the IRS or your state's business filing office to confirm your information is correct, then try again with a different bank.
Some banks have restrictions on the types of businesses they will serve. They may decline accounts for cannabis businesses, money services, or other industries they consider high-risk. If one bank declines you, another may not — shop around before assuming your business cannot get a bank account.
Frequently Asked Questions
Can I open a business account without an EIN?
Some banks allow sole proprietors to use a Social Security number instead of an EIN, but most now require an EIN for all business accounts. Getting an EIN is free and takes minutes online, so it is simpler to obtain one before you explore. Partnerships, LLCs, and corporations cannot open accounts without an EIN.
What if my business is not registered with the state yet?
You can still open a business account, but the bank will verify that your business structure documents are filed or in process. If you have not filed yet, file your Articles of Organization or Incorporation before explore for the account — this prevents verification delays. Some banks will hold your account process while you file.
Do I need to bring my business license to open an account?
A business license is not required by most banks, though it helps if you have one. The bank primarily needs proof of your business structure (Articles of Organization, Articles of Incorporation, or a DBA certificate) and your EIN. If your state or city requires a business license for your type of work, bring it — it speeds up verification.
How much money do I need to deposit to open the account?
Minimum opening deposits vary by bank and account type, ranging from zero to several thousand dollars. Some banks waive the minimum if you set up direct deposit or maintain a certain monthly balance. Ask the bank about their specific requirements before you explore.
What if the bank says my documents do not match their records?
Contact the IRS (for your EIN) or your state's business filing office to confirm your information is correct and current. If there is an error in their records, correct it before reapplying. If your information is correct but the bank still sees a mismatch, ask the bank which specific field does not match — this helps you troubleshoot with the government agency.
