What you need before you walk in

A business bank account separates your personal money from your business money, which protects you legally and makes taxes far simpler. Most banks will open one for you in a single visit or online session, but they need specific documents first — showing up without them wastes time.

The core documents are: proof of business ownership (articles of incorporation, partnership agreement, or sole proprietor ID), a federal Employer Identification Number (EIN) from the IRS, and a government-issued ID in your name. Some banks also ask for a business license from your city or county. If you are a sole proprietor without an EIN yet, you can use your Social Security number instead, though getting an EIN takes about 15 minutes online at irs.gov.

Call the bank branch or check their website before you go — requirements vary between institutions and between account types. A basic business checking account has simpler requirements than a merchant account that processes credit cards.

Key Takeaways

  • Bring your business formation documents, an EIN or Social Security number, and a government ID — these three items are required by nearly every bank.
  • Sole proprietors can open an account using their Social Security number, but an EIN from the IRS takes 15 minutes to obtain online and is often preferred by banks.
  • Banks vary in what they require, so contact your chosen bank before visiting to confirm you have the right paperwork.
  • The account typically opens the same day, though some banks mail the debit card and checks separately, arriving within one to two weeks.

Gather your business formation documents

The bank needs proof that your business legally exists. What counts depends on your business structure. If you formed an LLC or corporation, bring your articles of incorporation or articles of organization — the document you filed with your state's secretary of state office. If you are a partnership, bring the partnership agreement. If you are a sole proprietor, you may only need your government ID and EIN, though some banks ask for a business license.

You can find these documents by logging into your state's secretary of state website or by contacting the office directly. If you have not yet formed your business officially, you can still open an account as a sole proprietor using your Social Security number, but you will need to do the formation work before you can hire employees or claim business deductions on your taxes.

Get an EIN from the IRS

An Employer Identification Number is a nine-digit code the IRS uses to track your business for tax purposes. You need one if you have employees, operate as an LLC or corporation, or file certain business tax returns. Even if you do not technically need one, most banks prefer it because it ties the account to your business rather than your personal Social Security number.

Apply online at irs.gov/ein — the form takes about 15 minutes and you get your number immediately. You can also apply by phone at 1-800-829-4933 or by mail, but online is fastest. There is no cost. Print or save your confirmation letter; some banks ask to see it.

Choose a bank and account type

Not all banks offer business accounts, and fees vary widely. Community banks and credit unions often have simpler requirements and lower monthly fees than national chains. Online banks typically have no monthly fees but offer fewer in-person services.

Decide what you actually need: basic checking, or do you need to process credit card payments, accept ACH transfers, or handle payroll? A basic business checking account is straightforward to open. Merchant services (credit card processing) and payroll features may require additional underwriting and take longer to set up. Start with checking; you can add services later.

Visit the bank or open an account online

Bring your government ID, your business formation documents, and your EIN confirmation letter (or Social Security number if you do not have an EIN yet). Some banks let you start the process online and finish in a branch; others do it entirely online. A few still require you to visit in person.

The banker will verify your documents, ask about the nature of your business, and confirm the account details — business name, address, who can sign checks, and whether you want online banking. They will ask for an initial deposit, which varies by bank but is often $100 to $500 for a basic account. You will leave with a temporary debit card or checks, and the permanent ones arrive by mail within one to two weeks.

Set up online banking and link your accounts

Once the account is open, set up online banking immediately. This lets you see transactions, transfer money, and pay bills without visiting a branch. The bank will give you login credentials or a link to create them.

If you have a personal account at the same bank, you can link them for transfers. If you use accounting software like QuickBooks or Wave, connect your business account to it so transactions import automatically — this saves hours on bookkeeping each month. Most banks support this through a secure connection; the bank will walk you through it or direct you to their help center.

What happens if you do not have all the documents yet

If you have not filed your business formation documents with the state yet, you can still open an account as a sole proprietor using your Social Security number. Some banks will let you add an EIN later once you have one. Call ahead and ask whether the bank will hold the account open while you complete your formation paperwork, or whether you need to finish it first.

If you do not have a government ID, some banks accept a passport or state ID card. A few will accept other forms of identification, but this is less common. Ask the bank what they accept before you visit.

Frequently Asked Questions
