What you need before you walk into a bank
A business bank account requires proof that your business exists as a legal entity separate from you personally. The documents the bank will ask for depend on what type of business structure you have — sole proprietorship, LLC, S-corp, C-corp, or partnership — and they vary slightly by bank and state.
At minimum, bring a government-issued photo ID (your driver's license or passport), your Social Security Number or EIN, and proof of your business address. If you formed an LLC or corporation, you will need your Articles of Organization or Articles of Incorporation — the document you filed with your state when you created the business. If you operate as a sole proprietor under your own name, some banks will open an account with just your ID and SSN, though many now require an EIN even for sole proprietors.
Some banks also ask for a business license, a DBA (Doing Business As) certificate if you operate under a name different from your legal name, or a recent utility bill or lease showing your business address. Call the bank before you go in and ask what they specifically need for your business structure — this saves a trip back home for a missing document.
Key Takeaways
- You will need proof of your business structure (Articles of Organization for an LLC, Articles of Incorporation for a corporation, or an EIN for a sole proprietorship) plus a government ID and your Social Security Number or EIN.
- Different banks have different document requirements, so call ahead to confirm what you need to bring rather than showing up unprepared.
- Most banks can open an account the same day you visit, though some require a waiting period of one to three business days before you can use the account.
- Monthly fees, minimum balance requirements, and transaction limits vary widely between banks, so compare options before you choose.
- If you do not yet have an EIN, you can obtain one free from the IRS online or by phone before you open the account.
Getting an EIN if you do not have one yet
An Employer Identification Number (EIN) is a nine-digit number the IRS assigns to your business. You need one if you have employees, operate as an LLC or corporation, or file certain tax forms. Many banks now require an EIN even for sole proprietors, so it is worth getting one before you open the account.
You can obtain an EIN free from the IRS in three ways: online at irs.gov/ein (instant, takes about 15 minutes), by phone at 1-800-829-4933 (takes about 10 minutes, available Monday through Friday 7 a.m. to 10 p.m. Eastern time), or by mail using Form SS-4 (takes two to four weeks). The online option is fastest and requires no paperwork — you answer questions about your business and receive your EIN immediately.
Once you have your EIN, write it down and keep it with your other business documents. You will need it not only for the bank but also for hiring employees, filing taxes, and opening business credit accounts.
Choosing between banks and account types
Business checking accounts come in several varieties, and the right one depends on how many transactions you expect and whether you need features like merchant processing or payroll integration. A basic business checking account is the most common choice for small businesses — it lets you deposit checks and cash, pay bills by check or ACH transfer, and receive payments from customers.
Compare accounts on three concrete factors: monthly maintenance fees (which range from $0 to $25 or more), minimum balance requirements (some banks charge a fee if your balance drops below a set amount), and transaction limits (some accounts cap the number of deposits or withdrawals per month). Online banks often have lower fees and no minimum balance, while traditional banks may charge more but offer in-person service and a local branch.
If you plan to accept credit card or debit card payments from customers, ask whether the bank offers merchant services or can refer you to a processor. If you will have employees, confirm that the bank can handle payroll processing or ACH transfers to employee accounts. These features are not always included in the base account and may cost extra.
Documents to bring on the day you open the account
| Business Structure | Documents You Need |
|---|---|
| Sole Proprietorship | Government ID, SSN or EIN, proof of business address (utility bill or lease) |
| LLC | Government ID, SSN or EIN, Articles of Organization, proof of business address |
| S-Corp or C-Corp | Government ID, SSN or EIN, Articles of Incorporation, proof of business address |
| Partnership | Government ID, SSN or EIN, Partnership Agreement, proof of business address |
Bring originals or certified copies of your formation documents — photocopies are usually not accepted. If you do not have a physical business address yet (for example, if you work from home), most banks will accept your home address as your business address, though you may need to provide a utility bill or lease in your name.
If someone other than you will be authorized to sign checks or access the account, bring that person's government ID and SSN as well. The bank will need to verify their identity before adding them as a signer.
What happens after you open the account
Once the bank approves your account, you will receive a debit card, checks, and online banking login information. Some banks activate the account immediately; others place a hold of one to three business days before you can deposit funds or write checks. Ask the bank representative when you can start using the account.
Your first deposit may be subject to a hold — the bank may not let you withdraw the money for a few business days while they verify the check or transfer. This is normal and does not mean anything is wrong. After your first few deposits, most banks lift holds more quickly.
Set up online banking and bill pay as soon as you can access your account. This lets you monitor your balance, transfer money between accounts, and pay vendors without writing checks. Many banks also offer mobile apps so you can deposit checks by taking a photo.
Keeping your business and personal finances separate
The main reason to open a business account is to keep business money separate from personal money. This separation protects you legally — if your business is sued, creditors generally cannot go after your personal assets if you have maintained clear separation between the two accounts. It also makes tax time simpler because all your business income and expenses are in one place.
From the day you open the account, deposit all business income into the business account and pay all business expenses from it. Do not mix personal and business transactions. If you need money from the business, transfer it to your personal account as a draw or salary rather than paying personal bills directly from the business account.
Keep records of all deposits and withdrawals. Your bank will provide monthly statements, but you should also track transactions in accounting software or a spreadsheet so you can reconcile your records with the bank's each month. This catches errors early and makes tax filing much easier.
If the bank denies your account application
Banks sometimes deny business accounts because of issues with your personal credit, a history of overdrafts or fraud, or problems with your business formation documents. If this happens, ask the bank in writing why they denied the account — they are required to tell you.
If the reason is a credit issue, you can try other banks; some have less strict requirements than others. If the reason is a problem with your business formation documents, contact your state's Secretary of State office to confirm that your LLC or corporation is in good standing and that your paperwork was filed correctly. You may need to file an amendment or renew your registration.
If you have a history of overdrafts or fraud, some banks that specialize in second-chance business accounts may work with you, though they typically charge higher fees. Online banks sometimes have more flexible policies than traditional banks.
Frequently Asked Questions
Can I open a business account if my business is not yet registered with the state?
Most banks require proof that your business exists as a legal entity, which means you need to have filed your formation documents with your state. If you operate as a sole proprietor under your own name, some banks will open an account without formal registration, but many now require an EIN. It is faster to register your business first — the process takes a few days to a few weeks depending on your state.
Do I need a separate account if I am a sole proprietor?
You are not legally required to have a separate business account as a sole proprietor, but it is strongly recommended. A separate account makes it much easier to track business income and expenses for taxes, and it protects you if your business is sued. The IRS also looks more favorably on businesses that maintain clear separation between personal and business finances.
How long does it take to open a business bank account?
The account itself usually opens the same day you visit the bank or apply online, though some banks place a one- to three-day hold before you can use it. Receiving your debit card and checks by mail takes five to ten business days. If you need to obtain an EIN first, add another day or two to the timeline.
What if I do not have a physical business address yet?
Most banks accept your home address as your business address if you work from home. You will need to provide proof of your address, such as a utility bill or lease in your name. Some banks also accept a UPS mailbox or virtual office address, but call ahead to confirm your bank's policy.
Can someone else open the account on behalf of my business?
No — the person opening the account must be the business owner or an authorized representative with power of attorney. The bank will verify the identity of whoever signs the account agreement. If you want someone else to have access to the account after it opens, you can add them as an authorized signer once the account is active.
