The documents banks require before you can open an account

Most banks want the same core set of documents: your Employer Identification Number (EIN) or Social Security Number, proof of your business structure, a government-issued ID, and proof of your business address. The exact list depends on whether you're a sole proprietor, LLC, S-corp, or C-corp—and on which bank you choose. Some banks ask for more; some ask for less. The fastest way forward is to call the bank's business account line and ask what they need before you gather anything.

What you bring matters because banks are required by federal law to verify your identity and the legitimacy of your business. They're not being difficult—they're following anti-money-laundering rules. Having the right papers ready means you can open the account in one visit instead of three.

Key Takeaways

  • Every bank requires a government-issued photo ID for the person opening the account, plus proof that your business actually exists.
  • An EIN (Employer Identification Number) is required for most business structures, but sole proprietors can use their Social Security Number instead.
  • You'll need to show proof of your business address—a lease, utility bill, or business license all work, depending on the bank.
  • The specific documents vary by bank and business type, so calling ahead saves you a trip back home for a missing form.
  • Bringing originals or certified copies is safer than bringing photocopies, though many banks will accept either.

Documents every business owner needs to bring

Start with your own identification. Bring a current government-issued photo ID—a driver's license, passport, or state ID card. The bank will not open an account without it, and it must not be expired. If you're opening the account in person, the person whose name is on the ID must be present.

Next, bring proof of your business structure. What that looks like depends on what you are:

  • Sole proprietor: A business license from your city or county, or a DBA (Doing Business As) certificate if you're operating under a name different from your own. Some banks accept just the business license; others want the DBA filing too.
  • LLC: Your Articles of Organization, filed with your state. Bring the original or a certified copy from your state's Secretary of State office.
  • S-corp or C-corp: Your Articles of Incorporation, also from your state's Secretary of State. Again, original or certified copy.
  • Partnership: Your Partnership Agreement and the Articles of Partnership filed with your state.

If your business is brand new and you haven't received your official paperwork yet, call the bank before you go. Some will let you open an account with a receipt showing you've filed; others will wait until the documents arrive.

Proof of your business address

Banks need to know where your business operates. Bring one of these:

  • A commercial lease or rental agreement with your business name on it.
  • A utility bill (electric, gas, water, internet) in your business name, dated within the last 60 to 90 days.
  • A business license showing your business address.
  • A property deed or mortgage statement if you own the building.
  • A letter from your landlord on letterhead, confirming you rent the space and listing the address.

If you work from home, bring a utility bill or mortgage statement in your name at that address. Some banks are stricter about home-based businesses and may ask for additional documentation, so mention it when you call ahead.

Your tax identification number

You'll need either an EIN or your Social Security Number. An EIN is a nine-digit number issued by the IRS to identify your business for tax purposes. You get one free by applying online at irs.gov, and the IRS usually issues it the same day.

You must have an EIN if you're an LLC, S-corp, C-corp, or partnership. Sole proprietors can use their Social Security Number instead, though many choose to get an EIN anyway for privacy and to keep business and personal finances separate.

If you don't have an EIN yet, apply for one before you go to the bank. It takes minutes online. If you're opening the account the same day you apply, bring the confirmation page from the IRS website showing your application was submitted—some banks will accept that temporarily while the official number processes.

Additional documents some banks request

Depending on the bank and your business type, you may be asked for:

  • A business plan or description: A one-page summary of what your business does. Not formal—just enough for the bank to understand the industry.
  • Proof of ownership: If someone other than you will be signing checks or accessing the account, bring their government ID and a document showing they're authorized (like an LLC operating agreement listing them as a member).
  • Resolutions or authorization documents: For corporations, banks sometimes ask for a corporate resolution authorizing the account opening. Your corporate bylaws or a board resolution will cover this.
  • Tax returns: If your business has been operating for more than a year, some banks ask to see the last year's tax return. This is less common for new accounts but happens occasionally.
  • A voided check: If you're ordering checks in advance, bring a sample or ask the bank to provide one.

Online banks typically ask for fewer documents than brick-and-mortar banks. They may only need your EIN, a photo ID, and proof of address—all uploaded as images. Call or check the bank's website to see what they accept before you apply.

What to bring originals of versus copies

Bring originals of your government-issued ID and your Articles of Organization or Incorporation. Banks will look at these in person and hand them back. For everything else—utility bills, business licenses, leases—photocopies or digital images usually work fine.

If you're applying online, you'll upload images of your documents. Make sure they're clear, show all four corners of the page, and are in color if the document has color elements. Blurry or cropped images often get rejected, and the bank will ask you to resubmit.

Certified copies—documents stamped by the government office that issued them—carry more weight than photocopies if there's any question about authenticity. If you're concerned a photocopy might not be accepted, order a certified copy from your state's Secretary of State office. It costs $5 to $15 and takes a few days.

What happens if you're missing a document

If you show up without something the bank needs, they'll tell you what's missing and ask you to come back. This is why calling ahead matters—you avoid the wasted trip. If you're applying online and a document is rejected, the bank will email you explaining why and ask you to resubmit a clearer version or a different document.

If you don't have your Articles of Organization yet because you just filed, ask the bank if they'll accept a filing receipt or confirmation email from your state. Many will, with the understanding that you'll provide the official document once it arrives. Get this agreement in writing or in an email so there's no confusion later.

If you're a sole proprietor without a DBA or business license yet, some banks will open an account under your Social Security Number and let you add the business name later once you have the paperwork. Others won't. This is another reason to call first.

Frequently Asked Questions

Can I open a business checking account without an EIN?

Yes, if you're a sole proprietor. You can use your Social Security Number instead. However, if you're an LLC, partnership, or corporation, you must have an EIN—the bank cannot open the account without it. You can get an EIN for free online at irs.gov in minutes.

What if I don't have a physical business address yet?

Use your home address. Bring a utility bill or mortgage statement in your name at that address as proof. If you're planning to rent a commercial space but haven't signed the lease yet, some banks will let you use a temporary address and update it once you move, though you'll need to call and ask first.

Do I need to bring original documents or are copies okay?

Bring originals of your government ID and your Articles of Organization or Incorporation—the bank will examine them and return them. For everything else, copies or digital images usually work. If applying online, upload clear color images showing all four corners of each page.

How long does it take to open an account once I have all the documents?

In person, usually 15 to 30 minutes if everything is in order. Online, it can take anywhere from a few minutes to a few business days, depending on the bank's verification process. Some banks issue a temporary account number the same day and mail your debit card later.

What if the bank asks for documents I don't have?

Ask the bank what alternative documents they'll accept. For example, if they want a utility bill but you don't have one in your business name, ask if a lease or business license will work instead. Banks have some flexibility—they just need to verify your identity and that your business exists.
