What you need before you walk in

A business bank account requires two categories of documents: proof that your business exists as a legal entity, and proof of your identity. The exact list depends on your business structure — a sole proprietorship needs different paperwork than an LLC or corporation — and on the bank's own requirements, which vary.

Most banks will ask for your Social Security number or Employer Identification Number (EIN), a government-issued photo ID, and documentation showing your business name and structure. Some will also want to see a recent business address, proof of business registration, and sometimes a voided check or initial deposit amount. Call the bank before you go; their checklist is the authoritative one for that institution.

Key Takeaways

  • You will need a government-issued photo ID and either your Social Security number or an EIN, depending on your business structure.
  • Sole proprietors typically need fewer documents than LLCs or corporations, which must provide articles of organization or incorporation.
  • Most banks require proof of your business address and some form of business registration or license, though requirements differ by bank and state.
  • Calling the bank's business banking line before you visit saves time and prevents rejected applications due to missing documents.
  • Some banks require an initial deposit or minimum balance; confirm the amount before opening the account.

Documents for a sole proprietorship

If you operate as a sole proprietor — meaning you are the only owner and have not registered as an LLC or corporation — you can often open a business account with just your Social Security number and a government-issued ID. The bank will use your personal tax ID rather than a separate business EIN.

However, you will still need to show that you operate a business under that name. Bring a copy of your business license (issued by your city or county), a DBA certificate (Doing Business As, filed with your county clerk if you use a name other than your legal name), or a recent business registration document. If you do not have formal registration, some banks will accept a business card, invoice, or website printout as proof the business exists.

Documents for an LLC or corporation

An LLC or corporation requires more formal documentation because these are separate legal entities. You will need your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation), filed with your state's Secretary of State office. These documents prove the business is registered and show the ownership structure.

You will also need an EIN, which is a nine-digit tax ID issued by the IRS. You can obtain an EIN for free through the IRS website (irs.gov) or by phone; it takes minutes to get one. Bring the EIN letter or documentation showing the number. Additionally, bring your government-issued photo ID and the name and address of at least one owner or authorized representative who will be on the account.

Some banks ask for a resolution or certificate of good standing from your state, which proves the business is in good legal standing. You can request this from your state's Secretary of State office, though not all banks require it.

Proof of identity and address

Every bank requires at least one government-issued photo ID — a driver's license, passport, or state ID card. This must be current and match the name on the account application.

For your business address, bring a recent utility bill, lease agreement, or mortgage statement showing the business location. If you work from home, a utility bill with your home address usually suffices. Some banks accept a business license or registration document as proof of address instead. If your business is brand new and you have not yet received mail at the location, ask the bank whether a signed lease or rental agreement will work.

EIN and tax documentation

An EIN is required for most business structures except sole proprietorships, which can use the owner's Social Security number. If you have not yet obtained an EIN, you can apply online at irs.gov/ein in minutes, or call the IRS at 1-800-829-4933. The EIN is free and you receive it immediately.

Some banks may ask to see your Form SS-4 (the IRS form you filed to request the EIN) or an IRS letter confirming the EIN. If you applied online, print the confirmation page. If you applied by phone, the IRS will mail the official letter within two weeks, but most banks will accept the online confirmation in the meantime.

You do not need to have filed taxes yet or have a business tax return on file. The bank only needs proof the EIN exists.

Initial deposit and account minimums

Many banks require an initial deposit to open the account, though the amount varies widely — some require $25, others $500 or more. A few banks have no minimum. Ask about this before you visit so you know how much cash or a check to bring.

Some accounts also carry a minimum balance requirement to avoid monthly fees. Confirm whether the account you want has a balance minimum and what it is. If you cannot meet it regularly, ask whether the bank offers a different account type without that requirement.

What you do not need

You do not need to have a business license, business tax return, or business credit history to open an account. You do not need to be profitable or have been in business for any length of time. You do not need a personal credit check (though some banks may run one). You do not need to have a separate business phone number or website.

If you are opening the account as a representative of the business but are not the owner, bring a letter from the owner authorizing you to open the account, along with your own ID.

Frequently Asked Questions

Can I open a business account online, or do I have to go to a branch?

Many banks allow you to start the process online, but most require at least one in-person visit or video call to verify your identity and sign documents. Some online-only banks complete the entire process remotely. Call your bank to ask whether they offer remote account opening and what documents they need you to upload or mail.

What if I do not have an EIN yet?

You can obtain an EIN for free and immediately through irs.gov. If you are a sole proprietor, you can use your Social Security number instead. Some banks will let you open the account with a Social Security number and add the EIN later once you receive it.

Do I need a separate business address, or can I use my home address?

You can use your home address. Bring a utility bill or other document showing your home as the business location. If you rent a mailbox or use a virtual office address, ask the bank whether they accept that; some do, some do not.

What happens if I bring the wrong documents?

The bank will tell you what is missing and ask you to return with the correct paperwork. This is why calling ahead is worth the five minutes — you can confirm the exact list and avoid a second trip.

Can someone else open the account on behalf of the business?

Yes, but you will need a letter from the business owner authorizing that person to open the account, along with that person's government-issued ID. Some banks also require the owner to be present or to sign documents remotely.
