What you need before you open a business account

A business bank account separates your personal money from your business money, which protects both your finances and your business if something goes wrong. Most banks require you to show up with specific documents and information — the exact list depends on your business structure and the bank, but the core items are always the same.

You will need proof of your business existence (a registration document, DBA filing, or articles of incorporation), a government-issued ID, your Social Security number or Employer Identification Number (EIN), and proof of your business address. If you are a sole proprietor, a DBA filing from your county clerk or secretary of state is usually enough. If you are an LLC or corporation, you need the formation documents from your state.

Some banks also ask for a business plan summary, recent tax returns, or proof of initial deposit amount. Call the bank before you go in — their requirements vary, and you do not want to make the trip twice.

Key Takeaways

  • You need a government ID, proof of business existence (DBA or formation documents), and your Social Security number or EIN before you walk into a bank.
  • Sole proprietors can often use a DBA filing; LLCs and corporations need their state formation documents.
  • Banks have different requirements, so call ahead to confirm what documents they want and whether there is a minimum opening deposit.
  • The account usually opens the same day if you bring everything, though some banks take one to three business days to activate it.

Step 1: Choose your business structure and register it

Your business structure — sole proprietorship, LLC, S-corp, or C-corp — determines what documents the bank will ask for. If you are operating under your own name with no formal registration, you are a sole proprietor and you may only need your personal ID and Social Security number. If you want to use a different business name, you need a DBA (Doing Business As) filing from your county clerk or secretary of state.

If you have already formed an LLC or corporation, you have formation documents from your state — usually called articles of incorporation or articles of organization. These are what the bank will ask to see. If you have not formed one yet and think you need to, check your state's secretary of state website; most states let you file online and receive confirmation in a few days.

Step 2: Get an Employer Identification Number if you need one

An EIN is a nine-digit number the IRS assigns to your business. If you are a sole proprietor with no employees, you can use your Social Security number instead. If you have employees, are an LLC with more than one owner, or are a corporation, you need an EIN.

You can get an EIN free from the IRS website (irs.gov) in about 15 minutes. You fill out Form SS-4 online, and the IRS gives you the number immediately. You can also call the IRS at 1-800-829-4933 or mail the form, but online is fastest. Write down the number — you will need it when you open the account.

Step 3: Gather your documents and call the bank

Before you visit a bank branch, call and ask what they need. Tell them your business structure (sole proprietor, LLC, corporation) and ask for a complete list. Most banks want the same things, but some have extra requirements — a minimum opening deposit, proof of business address, or recent tax returns if your business is established.

Bring originals or certified copies of your formation documents, your government ID, your Social Security number or EIN, and a utility bill or lease showing your business address. If the bank asks for a business plan or financial projections, a one-page summary is usually enough.

Step 4: Visit the bank and complete the application

Go to a branch during business hours with all your documents. A banker will review what you brought, ask questions about your business (what you do, how much you expect to deposit each month, how many checks you will write), and have you sign the account agreement. This usually takes 20 to 30 minutes.

The banker will also ask about services — whether you want a debit card, online banking, merchant processing to take card payments, or a business credit card. You do not have to decide on everything that day; you can add services later. Ask about monthly fees, minimum balance requirements, and whether they waive fees for new accounts.

Step 5: Activate the account and set up online banking

Some banks activate your account the same day; others take one to three business days. Ask when you can start using it. Once it is active, set up online banking so you can check your balance, transfer money, and download statements from home. The bank will give you login instructions or send them by email.

Order checks if you need them — most banks charge for printed checks, though some offer a small number free. Set up automatic transfers from your personal account if you are funding the business with your own money. If you have employees, ask about payroll services or direct deposit setup.

What happens if the bank says no

Banks sometimes decline new business accounts if your personal credit is very poor, if you have unpaid tax liens, or if your business is in a high-risk industry (like cannabis, even in states where it is legal). If one bank declines you, try another — different banks have different risk standards.

Community banks and credit unions are sometimes more flexible than large national banks. If you are having trouble, ask the bank what specifically disqualified you; sometimes it is something you can fix (like resolving a tax issue) before you try again.

Frequently Asked Questions

Can I open a business account online without going to the bank?

Some banks let you open an account online, but most still require you to visit a branch with your original documents. A few online banks (like Mercury or Brex) do the whole process remotely, but they have stricter requirements and higher fees. Call your bank to ask whether they offer online opening.

Do I need an EIN if I am a sole proprietor?

No. You can use your Social Security number instead. You only need an EIN if you have employees, are an LLC with multiple owners, or are a corporation. Getting one is free and takes 15 minutes on the IRS website if you decide you want one later.

What is the minimum amount I need to deposit to open the account?

It varies by bank. Some have no minimum; others require $100 to $500. A few require $1,000 or more. Call ahead and ask — this is one of the most important things to confirm before you visit.

How long does it take to open a business account?

The visit itself takes 20 to 30 minutes. The account is usually active the same day or within one to three business days. Some banks hold deposits for a few days before they clear, so ask when you can actually start using the money.

Can I use a business account for personal expenses?

Legally, no. Mixing personal and business money can hurt you if your business is sued or audited — it may cost you liability protection or create tax problems. Keep them separate. If you need personal money, take a documented withdrawal or owner's draw instead.
