What you need before you open a business account

A business bank account separates your personal money from your business money, which protects you legally and makes taxes simpler. Most banks require you to have your business structure set up first — that means you need either a sole proprietorship, partnership, LLC, S-corp, or C-corp already registered with your state. You cannot open a business account as just an idea.

Banks also ask for an Employer Identification Number (EIN), which you get free from the IRS. If you are a sole proprietor with no employees, you can use your Social Security number instead, but an EIN keeps your personal and business finances more separate. You will need to bring a government-issued ID, proof of your business address, and your business registration documents — the exact paperwork varies by state and business type.

Key Takeaways

  • You must register your business with your state before opening a business account; the bank will ask for proof of that registration.
  • An EIN from the IRS is free and takes about 15 minutes to request online, though sole proprietors can use their Social Security number instead.
  • Bring your government ID, business registration documents, and proof of your business address to the bank in person or prepare to upload them online.
  • Different banks charge different monthly fees and require different minimum balances, so compare options before you choose.

Getting an EIN from the IRS

Visit the IRS website at irs.gov and search for "Apply for an EIN." You can request one online for free, and the IRS will issue it to you immediately. The process takes about 15 minutes and asks for your business name, business structure, and the reason you need an EIN. You do not need to have filed taxes yet or have a physical office — the IRS just needs to know your business exists.

If you prefer not to apply online, you can call the IRS Business and Specialty Tax Line at 1-800-829-4933 and request an EIN over the phone. You can also mail Form SS-4 to the IRS, but that takes several weeks. For most people, the online option is fastest. Write down your EIN as soon as you receive it — you will need it when you walk into the bank.

Registering your business with your state

Before the bank will open an account, you need proof that your business is registered. For a sole proprietorship, this might be a DBA (Doing Business As) certificate filed with your county clerk. For an LLC or corporation, you need Articles of Organization or Articles of Incorporation filed with your state's Secretary of State office. Each state has a different website and process, so search "[your state] Secretary of State" to find the right office.

Most states let you file online and receive your registration documents within days. Some charge a filing fee between $50 and $300 depending on the state and business type. Bring the original or certified copy of your registration documents to the bank — a photocopy or screenshot usually will not work. If you have not registered yet, do that before you schedule a bank appointment.

What to bring to the bank

Bring your government-issued photo ID (driver's license or passport), your EIN letter from the IRS, your business registration documents, and proof of your business address. Proof of address can be a utility bill, lease, or mortgage statement in your business name, or a commercial lease if you rent office space. If you work from home, a utility bill with your home address is usually acceptable.

Some banks also ask for a business plan or a letter describing what your business does, though this is less common for small businesses. Call the bank branch ahead of time and ask what they need — different branches sometimes have different requirements. If you are opening the account online instead of in person, the bank will tell you which documents to upload and in what format.

Choosing between in-person and online account opening

Large national banks like Chase, Bank of America, and Wells Fargo let you open a business account online, though you may still need to visit a branch to deposit your first check or verify your identity. Online-only banks like Mercury, Brex, and Wise often have faster approval and lower fees, but they may not offer the same services as a traditional bank — for example, some do not accept cash deposits or have physical locations.

If you need to deposit cash regularly or want to speak to someone in person, a traditional bank branch is usually better. If you mostly pay by check or transfer and do not need physical deposits, an online bank can save you money on fees. Compare the monthly fee, minimum balance requirement, and services offered before you decide. Many banks waive the monthly fee if you keep a certain balance or set up direct deposit.

What happens after you open the account

Once your account is open, the bank will give you checks, a debit card, and online access. You can start depositing money and paying bills right away. Some banks take a few days to activate your debit card or online access, so ask when you can expect those to be ready.

Keep your business and personal finances separate from day one — deposit all business income into this account and pay all business expenses from it. This separation protects you if your business is sued and makes tax time much simpler. Your accountant or tax preparer will thank you when they do not have to sort through mixed personal and business transactions.

Frequently Asked Questions

Can I open a business account without an EIN?

Yes, if you are a sole proprietor, you can use your Social Security number instead of an EIN. However, an EIN keeps your personal and business finances more separate and is free to get, so most accountants recommend it even if it is not required.

How long does it take to open a business account?

In person, it usually takes 15 to 30 minutes. Online, approval can take anywhere from a few minutes to a few business days depending on the bank. Some banks activate your account immediately; others wait for you to make your first deposit before they turn on online access.

What if my business is not registered yet?

You cannot open a business account without proof of registration. Register your business with your state first — this usually takes a few days to a week online. Once you have your registration documents, you can open the account.

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 you if your business is sued. The IRS also looks more favorably on businesses that keep separate records.

What is the difference between a business checking and business savings account?

A business checking account is for daily transactions — paying bills, depositing income, writing checks. A business savings account earns interest but usually has limits on how many times you can withdraw per month. Most small businesses open both: checking for operations and savings to set aside money for taxes or emergencies.
