Documents and information you'll need before you walk in
Most banks want the same core set of documents, though the exact list varies by bank and by the type of business you're running. Have your Employer Identification Number (EIN) ready — this is the federal tax ID for your business, separate from your Social Security number. If you're a sole proprietor, you can use your SSN instead, but an EIN keeps your personal and business finances clearer.
Bring a government-issued photo ID (driver's license or passport) and your Social Security number. You'll also need proof of your business address — a utility bill, lease, or mortgage statement dated within the last 60 days works. Some banks accept a business license or articles of incorporation as proof of address instead.
If your business is structured as an LLC, corporation, or partnership, bring the formation documents — the articles of incorporation, articles of organization, or partnership agreement. A sole proprietor usually doesn't need formation documents, though some banks ask for a DBA (doing business as) certificate if you're operating under a name different from your legal name.
Key Takeaways
- You need a government photo ID, your Social Security number or EIN, and proof of your business address dated within the last 60 days.
- If your business is an LLC, corporation, or partnership, bring the formation documents that show the structure and owners.
- Different banks have different secondary requirements — some ask for a business license, others for a DBA certificate, and some want to see recent business activity or tax returns.
- Sole proprietors can open an account with just an SSN, but using an EIN instead keeps personal and business finances separate.
- Call the bank before you go in to confirm their exact list, because requirements shift between branches and account types.
What banks ask for beyond the basics
After the core documents, banks diverge. Some want to see a business license from your state or city — this is especially common if you're in a regulated industry like food service, childcare, or contracting. Others ask for a DBA certificate, which you file with your county or state to register your business name.
Newer banks or those opening accounts remotely may ask for a recent tax return, a business plan, or proof of business activity — a few months of bank statements from a personal account you've been using for business, or invoices showing you're actually operating. Banks are trying to verify that your business is real and that you're not opening the account for something they won't support.
If you have a co-owner or multiple signers, bring their IDs and Social Security numbers too. Some banks require all owners to be present; others let you add signers later. Ask when you call.
Why banks ask for these documents
The documents serve two purposes: verifying your identity and confirming your business exists. Banks are required by federal law to know who owns the account and what the account will be used for — this is part of anti-money-laundering compliance. They're not trying to make opening an account hard; they're trying to avoid opening accounts that will be used for fraud or illegal activity.
The address verification and formation documents also protect you. They create a paper trail showing that the account belongs to your business, not to you personally. This matters if you're ever audited or if there's a dispute — the bank's records will show the account was opened as a business account, which affects how the IRS treats it and how creditors can reach it.
What you don't need (and shouldn't waste time gathering)
You do not need a business plan, a pitch deck, or a detailed explanation of what you'll use the account for — unless the bank specifically asks. You do not need to have already filed taxes or to have a certain amount of revenue. You do not need a business credit score or business credit history.
You do not need to have your business registered with the state if you're a sole proprietor operating under your own name. Many sole proprietors never register anything and still open business accounts. If you're using a different name, you'll need the DBA, but that's a filing, not a document you gather.
Do not bring original documents unless the bank asks — bring copies. Banks will usually make copies themselves and return originals to you.
How to find out what your specific bank wants
Call the bank's business banking line before you go in. Tell them your business structure (sole proprietor, LLC, corporation, or partnership) and ask for their exact document list. This takes five minutes and saves you a wasted trip. Different branches sometimes have different requirements, and requirements change — what worked six months ago might not work now.
If you're opening an account online or by mail, the bank will send you a checklist. Read it carefully and gather everything before you start the process. Online accounts often move faster, but they also reject applications more often because documents are missing or unclear.
If you're opening an account at a bank that doesn't have a local branch, ask whether they accept documents by email, upload, or mail. Some banks want originals; others are fine with scans or photos taken on your phone.
Timeline from documents to open account
If you walk in with everything the bank asks for, you can usually open an account the same day. The bank will verify your identity, run a background check (which takes minutes), and hand you a debit card and checkbook before you leave — or they'll mail them within a week.
If you're missing something, the bank will tell you what's needed and how long you have to provide it. Most banks give you 30 days. If you're opening online, the process usually takes three to five business days from the time you submit all documents.
The slowest part is usually the background check, which banks run on all business account owners. This is not a credit check — it's a check for fraud, money laundering, or sanctions violations. It rarely causes problems unless you have a criminal conviction related to financial crimes or you're on a government sanctions list.
What happens if you don't have an EIN yet
You can open a business account using your Social Security number instead of an EIN. Many sole proprietors do this. However, if you plan to hire employees or if your business is structured as an LLC or corporation, you'll need an EIN eventually — and it's easier to get one before you open the account.
You can get an EIN for free from the IRS. Apply online at irs.gov/ein, by phone at 1-800-829-4933, or by mail using Form SS-4. Online is fastest — you get your EIN immediately. By phone, you get it the same day. By mail, it takes about four weeks.
Some banks will let you open an account with an application for an EIN (showing you've applied but haven't received the number yet), though this is less common. Call ahead if you're in this situation.
Frequently Asked Questions
Can I open a business account if I'm a sole proprietor with no business license?
Yes. Sole proprietors don't need a business license in most states if they're operating under their own name. You can open an account with just your ID, Social Security number, and proof of address. If you're using a different business name, you'll need a DBA certificate, which you file with your county.
Do I need to bring my business partner if we're opening a joint account?
Most banks require all owners to be present or to sign documents in front of a notary. Some banks let you add owners after opening the account. Call the bank first — if they require everyone present and your partner can't make it, you may be able to open the account alone and add them later.
What if the bank rejects my documents?
Banks reject documents most often because they're unclear, outdated, or don't match the name on your ID. Ask the bank exactly what's wrong and what they need instead. If they reject your application entirely, ask why — it's usually because of the background check, not the documents. You can ask them to review the decision or try a different bank.
Can I open a business account online without going to a branch?
Yes, many banks offer online business account opening. You'll upload photos of your documents and verify your identity through the app. The process takes three to five business days. Some banks still require you to visit a branch or have a notary verify your signature, so check before you start.
Do I need a business address that's different from my home?
No. You can use your home address as your business address. The bank just needs proof that you live there or operate there — a utility bill or lease in your name works. Some banks accept a UPS box or virtual office address, but this is less common and may trigger extra questions.
