What a bank will ask for before opening your account

Banks require specific documents and information before they will open a business account. The exact list depends on your business structure — sole proprietorship, partnership, LLC, S-corp, or C-corp — and the bank itself. Most banks ask for proof of your business identity, proof of your personal identity, and proof that you are authorized to open the account on behalf of the business.

You will also need to provide a federal Employer Identification Number (EIN) or your Social Security Number if you operate as a sole proprietor. The bank will verify this number and run a background check. Some banks also ask for a business plan or recent tax returns, though this is more common for larger accounts or lines of credit.

Key Takeaways

  • You will need a government-issued ID, proof of your business address, and either an EIN or Social Security Number before any bank will open an account.
  • Sole proprietors typically use their Social Security Number, while LLCs, partnerships, and corporations must have an EIN from the IRS.
  • Different business structures require different documents — a sole proprietor needs fewer papers than an LLC or corporation.
  • Banks run background checks and verify your identity against government records, so bring original documents or certified copies, not photocopies.
  • Some banks ask for a business license, articles of incorporation, or operating agreement, while others do not — call ahead to ask what your chosen bank requires.

Documents for a sole proprietorship

If you operate as a sole proprietor, you are the business in the eyes of the law, so the bank needs proof of your identity and your business address. Bring a government-issued photo ID (driver's license, passport, or state ID card) and a recent utility bill, lease agreement, or mortgage statement showing your business address. If your business operates from your home, your home address counts.

You can use your Social Security Number instead of an EIN, though some banks prefer an EIN even for sole proprietors. If you want an EIN, you can request one free from the IRS at irs.gov — it takes about 15 minutes online and you receive the number immediately. Bring whichever number you choose, along with your ID and address proof, and most banks will open the account the same day.

Documents for an LLC, partnership, or corporation

These business structures are separate legal entities, so the bank needs proof that the business exists and proof that you have the authority to open an account on its behalf. Bring your articles of incorporation (for a corporation), articles of organization (for an LLC), or partnership agreement. The bank will want to see the original or a certified copy — a photocopy is usually not enough.

You will also need an EIN, which the IRS issues free. Apply at irs.gov or by mail using Form SS-4; the online application gives you the number immediately. Bring your EIN letter or the number itself, your business documents, your government-issued ID, and proof of your business address. Some banks also ask for a resolution or certificate of authority showing that you are authorized to sign on the account — ask your bank what it needs before you visit.

What "proof of business address" means

Banks need to verify that your business actually operates at the address you provide. A utility bill, lease, mortgage statement, or property tax bill in your business name works. If you use a virtual office address or a mailbox service, bring the agreement or receipt from that service showing your name and the address.

If you have not yet received a utility bill or lease in your business name, bring a recent bill in your personal name plus a signed lease or rental agreement for the business space. Some banks will also accept a letter from your landlord on letterhead confirming that you rent the space, though this is less common. Call the bank before you visit to ask what it will accept.

Background checks and verification

Banks run a background check on you and the business before opening the account. They verify your identity against government records, check for fraud or financial crime, and sometimes review your credit history. This process usually takes one to three business days, though some banks complete it the same day.

The bank will also check ChexSystems, a database of banking history. If you have had accounts closed for fraud, unpaid overdrafts, or other issues, the bank may decline to open an account or may require you to resolve those issues first. If you have been declined before, ask the bank what it found — you have the right to see your ChexSystems report and dispute errors.

What to bring to the bank

Bring originals or certified copies of all documents, not photocopies. Banks will not accept a photocopy of your ID or business license. Bring your government-issued photo ID, proof of your business address, your EIN letter or Social Security Number, and any business formation documents the bank requires. If you are opening the account on behalf of someone else, bring a power of attorney or written authorization from the business owner.

Bring a list of the owners and their addresses if the bank asks for it. Some banks also ask for a business plan, recent tax returns, or a list of expected monthly deposits — ask when you call to schedule an appointment. Arriving prepared speeds up the process and reduces the chance that the bank will ask you to come back with missing documents.

Differences between banks

Requirements vary by bank and by account type. A basic checking account usually requires fewer documents than a business savings account or a line of credit. Online banks often have simpler requirements than brick-and-mortar banks, though they may not accept certain document types or may require you to mail originals.

Credit unions sometimes have different rules than commercial banks, and some require you to be a member before opening a business account. Call or visit the website of the bank you want to use and ask what documents it needs for your business structure. This takes five minutes and prevents a wasted trip.

Frequently Asked Questions

Can I open a business account with just my Social Security Number?

Only if you are a sole proprietor. Partnerships, LLCs, and corporations must have an EIN. You can get an EIN free and instantly at irs.gov, so there is no reason to delay opening the account.

What if I do not have a business address yet?

You can use your home address or a virtual office address. If you use a mailbox service or coworking space, bring the agreement showing your name and the address. Some banks will also accept a letter from your landlord confirming the business location.

Do I need a business license to open a bank account?

Not always. Some banks ask for it, others do not. Call your bank and ask. If you need one, your city or county issues it — the process usually takes a few days to a few weeks depending on your location and business type.

How long does it take to open a business account?

If you bring all required documents, most banks open the account the same day or within one to three business days. The background check and verification process usually takes the longest. Online banks may take longer because they verify documents by mail or upload.

What happens if the bank declines to open an account?

The bank must tell you why. Common reasons are fraud or unpaid overdrafts on a previous account, which show up in ChexSystems. You can dispute errors in your ChexSystems report or resolve the underlying issue and try again at a different bank.
