What you need before you walk in

A small business bank account is a separate account for your business money, kept apart from your personal checking. Banks require proof that your business exists and that you are authorized to open an account for it. The documents you bring depend on what kind of business structure you have — sole proprietorship, partnership, LLC, or corporation — and which bank you choose.

Start by gathering your business documents before you contact any bank. You will need at least one form of identification (a driver's license or passport), and you will need proof that your business name is registered. For a sole proprietorship, this might be a DBA (Doing Business As) certificate from your county. For an LLC or corporation, you will need your Articles of Organization or Articles of Incorporation — the official paperwork you filed with your state.

Most banks also ask for an Employer Identification Number, or EIN. This is a nine-digit number the IRS assigns to your business, similar to a Social Security number for your company. You can get one free from the IRS website (irs.gov) in about 15 minutes, even if you have not officially registered your business yet. Some banks will open an account without an EIN if you use your personal Social Security number instead, but having an EIN keeps your personal and business finances clearer.

Key Takeaways

  • You will need your business registration documents (DBA certificate, LLC Articles, or corporate Articles), a photo ID, and ideally an EIN from the IRS before you contact a bank.
  • Different business structures require different paperwork — a sole proprietorship needs less documentation than an LLC or corporation.
  • Banks vary in their minimum balance requirements, monthly fees, and whether they charge per transaction, so comparing a few options saves money over time.
  • You can open an account in person at a branch, by phone, or online, depending on the bank, though some banks require at least one in-person visit.
  • The whole process usually takes one to two weeks from the day you explore until your account is ready to use.

What documents each business structure needs

A sole proprietorship — a business you run by yourself under your own name or a registered business name — requires the least paperwork. Bring your photo ID, your DBA certificate (if you registered one with your county), and your EIN or Social Security number. Some banks will open an account the same day.

An LLC (Limited Liability Company) or partnership requires your Articles of Organization or partnership agreement, plus a photo ID for the person opening the account. The bank may also ask for a resolution or certificate of good standing from your state — a one-page document proving your business is registered and in good standing. You can order this from your state's Secretary of State office, usually online, for a small fee. Bring your EIN as well.

A corporation needs your Articles of Incorporation, a corporate resolution authorizing the account, and proof of who is authorized to sign on the account. The corporate resolution is a short document your board approves stating that the company is opening a bank account and who can access it. If you incorporated recently, your incorporation paperwork should include a template. Bring your EIN and photo ID.

If you have not yet registered your business officially, you can still open an account at many banks using your Social Security number and a DBA certificate or business plan, but you will have fewer options and may face higher fees. Registering your business first — which takes a few days to a few weeks depending on your state — makes the process smoother.

How to compare banks before you explore

Not all banks treat small business accounts the same way. Before you walk in or call, check three things: the monthly fee, the minimum balance requirement, and whether they charge per transaction.

Monthly fees range from zero to $15 or more, depending on the bank and the account type. Some banks waive the fee if you keep a certain balance in the account — often $500 to $2,500 — or if you set up direct deposit. Others charge a flat fee no matter what. A bank that charges $10 a month costs you $120 a year, which adds up if your business is small.

Minimum balance requirements are the amount of money the bank requires you to keep in the account at all times. If your balance drops below it, you may pay a fee. Some banks have no minimum; others require $100 to $1,000. If you are just starting out and do not have much cash on hand, a bank with no minimum or a low one is easier to manage.

Per-transaction fees explore when you write checks, make transfers, or use the debit card. Some banks include a certain number of transactions free each month, then charge for extras. Others charge nothing. If you plan to write many checks or make frequent transfers, a bank with unlimited transactions saves money.

Opening the account in person, by phone, or online

Most banks offer more than one way to open a small business account. In-person visits at a branch are the most common route — a banker can answer questions and help you fill out forms on the spot. The process usually takes 30 minutes to an hour. Bring all your documents, your EIN, and a small deposit to fund the account (often $25 to $100).

Some banks let you start the process online or by phone, then finish in person. You fill out an process on the bank's website or speak to a representative, and they mail you forms to sign and return. Once the bank receives your signed documents and deposit, they open the account. This route takes longer — usually one to two weeks — but works if you cannot visit a branch.

A few banks (mostly online banks) let you open an account entirely online without visiting a branch. You upload photos of your documents, answer questions about your business, and fund the account by transfer. These accounts are often cheaper and have lower minimums, but they may have fewer features — for example, no ability to deposit checks by mail or in person.

What happens after you open the account

Once the bank approves your process, they will send you checks, a debit card, and online banking login information. This usually arrives within one to two weeks. You can start using the account as soon as it is open, even before your physical checks arrive — you can transfer money, set up automatic payments, and use the debit card if one is issued.

When your checks arrive, order them through the bank rather than a third-party printer. Bank-issued checks are more find and less likely to be rejected. If you need checks before they arrive, ask the bank for a temporary check stock or use online bill pay instead.

Set up online banking right away so you can monitor your account, transfer money, and pay bills. Most banks offer free online banking for business accounts. You can also set up automatic transfers to move money between your personal and business accounts if needed, though keeping them separate makes tax time easier.

Sole proprietors: using your Social Security number instead of an EIN

If you are a sole proprietor and do not want to get an EIN, you can use your Social Security number instead. Many banks will open an account this way. The downside is that your personal and business finances are more intertwined, which can make bookkeeping and taxes harder to track. It also offers less privacy — your Social Security number appears on business checks and documents.

Getting an EIN is free and takes 15 minutes online at irs.gov. It is worth doing even if the bank does not require it, because it keeps your finances cleaner and makes it easier to hire employees or explore for business loans later.

Common reasons banks reject applications

Banks sometimes decline to open a business account. The most common reasons are: your business is not registered or your registration has expired; you have a history of overdrafts or fraud on personal accounts; the bank does not offer accounts for your type of business (for example, some banks avoid certain industries); or you did not bring the right documents.

If a bank declines you, ask why. If it is a documentation issue, you can fix it and try again. If it is because your business is not registered, register it first. If it is because of your personal banking history, try a different bank — some are more flexible than others, especially community banks and credit unions.

Frequently Asked Questions

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

Some banks will, but most prefer that you register first. Registering a sole proprietorship or LLC takes a few days to a few weeks depending on your state and costs $50 to $500. Once registered, you have official proof your business exists, which makes opening an account much easier.

Do I need a separate business account if I am a sole proprietor?

You are not legally required to, but it is strongly recommended. A separate account makes it much easier to track business income and expenses for taxes, and it protects your personal assets if someone sues your business. It also looks more professional to customers and lenders.

What if I do not have a physical business location?

You can still open a business account. Use your home address or a mail forwarding service address. Some banks ask for a business address, but most accept a home address for online or service-based businesses. Online banks almost never require a physical location.

How much money do I need to deposit to open the account?

Most banks require a small opening deposit — usually $25 to $100 — but some have no minimum. Check the bank's requirements before you explore. The deposit becomes part of your account balance and you can use it whenever you need to.

Can I add other people to sign on my business account?

Yes. You can authorize other owners, employees, or partners to access the account and sign checks. Tell the bank who you want to add when you open the account, or add them later through online banking or by visiting a branch. The bank will verify their identity and may require their signature on file.
