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 your business structure — sole proprietorship, partnership, LLC, S-corp, or C-corp — and they vary by bank and state. Most banks will not open an account for a business that exists only as an idea; you need at least a registration document or tax ID number that shows the business is real.

The fastest path is to have your Employer Identification Number (EIN) ready before you go to the bank. You can get an EIN from the IRS at no cost, either online at irs.gov or by mail, and it takes minutes to hours online. If you are a sole proprietor with no employees, you can sometimes use your Social Security number instead, but banks increasingly prefer an EIN because it keeps your personal and business finances clearly separated.

Key Takeaways

  • You will need proof of your business structure — a registration document, EIN letter, or articles of incorporation — before any bank will open an account.
  • An EIN from the IRS is free and can be obtained online in minutes; most banks prefer it over using your Social Security number.
  • Bring a government-issued ID, your Social Security number or EIN, and a document showing your business address and ownership structure.
  • Different banks charge different monthly fees, require different minimum balances, and offer different numbers of free transactions, so comparing options before you go saves money over time.
  • The entire process usually takes one to two weeks from your first visit to the account being fully active and ready to use.

Documents you will need to bring

The exact list depends on your business structure. If you are a sole proprietor, bring your government-issued ID (driver's license or passport), your Social Security number or EIN, and proof of your business address — a utility bill, lease, or mortgage statement in your business name works. If your business is registered under a different name than your legal name, bring the DBA (Doing Business As) certificate from your state or county.

If you have an LLC, partnership, or corporation, bring your articles of incorporation or organization — the document you filed with your state when you registered the business. Bring your EIN letter from the IRS (the SS-4 form confirmation). Bring your government-issued ID and proof of your business address. If you are opening the account on behalf of the business rather than as the sole owner, bring a resolution or authorization letter signed by the owners stating that you have permission to open and manage the account.

Some banks also ask for a recent business tax return or proof of income, especially if your business is new and has no tax history yet. Call the bank branch before you go and ask what documents they specifically need; this saves a wasted trip.

Choosing between banks and account types

Business accounts are not all the same. A basic checking account is the most common choice — it lets you deposit checks, make transfers, and pay bills. Some banks also offer business savings accounts, money market accounts, or sweep accounts that move idle money into a higher-yield account automatically. For most new businesses, a checking account is enough to start.

Compare the monthly fee (which ranges from zero to $25 or more), the minimum balance required to waive the fee, the number of free transactions per month, and whether the bank charges per check or per deposit. Online banks like Mercury, Brex, and Novo often have lower or no monthly fees and no minimum balance, but they may not offer in-person services or accept cash deposits. Traditional banks like Chase, Bank of America, and Wells Fargo have branches everywhere but charge higher fees. Credit unions often have lower fees and better customer service but may have membership requirements or fewer ATMs.

Ask whether the bank offers a business debit card, online bill pay, and mobile check deposit — these are standard now, but not every account includes them. If you plan to accept credit card payments from customers, ask whether the bank offers merchant services or can refer you to a processor.

The application process at the bank

You can open an account in person at a branch, online through the bank's website, or over the phone with a banker. In-person is slowest but gives you a chance to ask questions and confirm you have everything the bank needs. Online is fastest — many banks let you open an account in 10 to 15 minutes — but you will need to upload photos of your documents and may need to verify your identity through a video call.

The banker or online form will ask for your business name, structure, address, phone number, and the names and Social Security numbers of all owners. They will ask what your business does and roughly how much money you expect to move through the account each month. They will run a background check and check ChexSystems (a banking history database) to see if you or your business have had problems with other banks. They will ask you to sign the account agreement and fee schedule.

Once you sign, the account is usually open immediately, though it may take one to two business days for the account number to be fully active and for you to be able to make transfers or deposits. Some banks send you a debit card and checks by mail, which takes five to ten business days.

What happens after the account opens

Your first deposit will likely be a small test deposit to confirm the account is working. You can deposit checks by mail, mobile app, or in person at a branch or ATM. You can set up automatic transfers from your personal account or from customer payments. You can pay bills online or by check. Keep your business and personal finances separate from day one — this is the whole reason you opened a business account, and it protects you if your business is ever audited or sued.

Set up online banking and mobile app access right away so you can monitor the account, catch fraud quickly, and pay bills on time. Most banks offer free online bill pay, which is faster and cheaper than mailing checks. If you have employees, you will eventually need to set up payroll through the bank or a payroll processor like Gusto or ADP; many banks can help you with this or refer you to a partner.

Common mistakes to avoid

The biggest mistake is mixing personal and business money. Even if your business is a sole proprietorship and you are legally allowed to use a personal account, doing so makes taxes harder, makes audits messier, and can expose your personal assets if the business is sued. Open a business account and use it only for business.

Another mistake is not comparing fees before you choose a bank. A $15 monthly fee sounds small, but it costs $180 a year. If you make 200 deposits a year and the bank charges $0.50 per deposit, that is another $100. Over five years, a cheap account saves you hundreds of dollars compared to a premium one.

Do not assume your personal bank is the best choice for your business. Many people open a business account at the same bank where they have a personal account for convenience, but that bank may charge higher fees or offer fewer features than competitors. Shop around.

Frequently Asked Questions

Can I open a business account if my business is not registered yet?

Most banks will not open an account without proof that your business exists as a legal entity. If you have not registered your business yet, you can do that first — it takes a few days to a few weeks depending on your state — or you can open a personal account and transfer it to a business account later once you have your registration documents.

Do I need an EIN if I am a sole proprietor with no employees?

No, you can use your Social Security number instead. However, an EIN is free and keeps your business finances more private, so most accountants recommend getting one anyway. You can apply online at irs.gov in minutes.

How long does it take to open a business account?

Online applications usually take 10 to 15 minutes to complete, and the account is often active the same day or within one business day. In-person applications at a branch take 30 minutes to an hour. Receiving your debit card and checks by mail takes five to ten business days.

What if the bank denies my application?

Banks usually deny applications because of a poor personal credit history, a history of overdrafts or fraud at other banks (shown in ChexSystems), or because the business structure or documents are incomplete. Ask the bank why you were denied. You can try another bank, or you can fix the issue (like paying off a debt) and reapply in a few months.

Can I have multiple business accounts at different banks?

Yes. Some businesses keep accounts at two banks for redundancy or to take advantage of different features — for example, one bank for checking and one for savings. Just make sure you can manage both accounts and that you are not violating any account agreements.
