The documents and information you'll need before you walk in

Opening a business checking account requires three categories of paperwork: proof that your business exists, proof of who owns it, and proof of your identity. Most banks want these in hand before you sit down, though some will let you start the process online and bring originals later. The exact list varies by bank and by what kind of business structure you have—a sole proprietorship needs different documents than an LLC or corporation.

The fastest path is to call the bank's business services line before you go in and ask for their specific checklist. Banks change their requirements, and some have different rules for accounts opened in person versus online. Knowing what they want saves a trip back home for a missing form.

Key Takeaways

  • You will need a government-issued ID for the owner, an Employer Identification Number (EIN) or Social Security Number, and proof your business is registered with your state.
  • The exact documents depend on your business structure: sole proprietorships need different paperwork than LLCs or corporations.
  • Most banks require an initial deposit to open the account, ranging from $0 to $500 depending on the institution.
  • Calling the bank's business services line before you visit tells you exactly what to bring and whether you can start online.

Proof of business existence and ownership

Banks need to see that your business is real and registered. For a sole proprietorship, this is usually a business license from your city or county, or a DBA (Doing Business As) certificate filed with your state. For an LLC or corporation, you need a copy of your Articles of Organization or Articles of Incorporation filed with your state's Secretary of State office. You can read these from your state's website if you filed online, or call the Secretary of State's office to request a certified copy.

Some banks will accept a screenshot or PDF of your filing confirmation. Others want the official document with the state seal. Ask the bank which they prefer before you spend money on certified copies—certified copies cost $5 to $25 per copy depending on the state.

Your personal identification and tax ID

Bring a government-issued photo ID—a driver's license, passport, or state ID card. The bank will scan or photocopy it. You will also need either an Employer Identification Number (EIN) or your Social Security Number. If your business is a sole proprietorship or single-member LLC, you can use your Social Security Number. If you have employees or your business structure is a partnership, LLC with multiple members, or corporation, you need an EIN.

You can get an EIN for free from the IRS website (irs.gov) in about 15 minutes. The IRS issues it when ready online. If you explore by phone or mail, it takes longer—phone applications take about 4 weeks, and mail takes 4 to 6 weeks. Most banks will not open your account without an EIN if you need one, so get it before you go in.

Proof of your business address

Banks need to know where your business operates. If you work from home, bring a utility bill, lease, or mortgage statement showing your home address. If you rent commercial space, bring your lease. If you use a virtual office or mailbox service, bring the agreement showing that address. Some banks will accept a recent utility bill in the business name; others want the lease or rental agreement.

The address does not have to match your personal address. Many sole proprietors use a home address, and that is fine. If you use a UPS box or mailbox service as your business address, tell the bank—some will accept it, others will not.

Initial deposit and account setup information

Most banks require an opening deposit to set up the account. This ranges from $0 to $500 depending on the bank and account type. Some banks waive the minimum if you set up direct deposit or maintain a certain monthly balance. Ask about this when you call—it may change which account type makes sense for you.

You will also need to decide how many owners will have signing authority on the account. If it is just you, this is straightforward. If you have partners or employees who need to sign checks or move money, bring their information too—the bank will need their names, addresses, and government-issued IDs. Some banks limit the number of authorized signers; ask before you bring extra people.

What happens if your business structure is unusual

Nonprofits, partnerships, and trusts have additional requirements. A nonprofit needs its IRS information letter (the document proving the IRS recognizes it as tax-exempt). A partnership needs a copy of the partnership agreement. A trust needs the trust document itself. If your business is a franchise, some banks want a copy of your franchise agreement.

If you are unsure whether your business structure counts as unusual, call the bank and describe it. They will tell you what extra documents to bring. Do not guess—showing up with the wrong paperwork wastes time.

Documents you do not need (but people often bring)

You do not need a business plan, tax returns from previous years, or a letter from your accountant. You do not need a business license from your state if you have filed an LLC or corporation—the state filing is enough. You do not need to bring your personal credit report or bank statements. Banks will pull your credit and banking history themselves if they need it.

Some banks ask about your expected monthly deposit volume or the purpose of the account. Be honest but brief. Banks are not trying to trap you—they are checking for money laundering risk. If you say you will deposit $50,000 a month from consulting work, that is normal. If you cannot explain where the money comes from, the bank may decline the account.

Frequently Asked Questions

Can I open a business checking account online without going to the bank?

Many banks let you start the process online and upload photos of your documents. You will usually need to verify your identity by video call or in person at a branch later. Some banks complete the entire process online if you have an existing personal account with them. Call your bank to ask whether they offer fully online business account opening.

What if I do not have an EIN yet?

Get one before you open the account if your business structure requires it. The IRS issues EINs free and when ready online at irs.gov. If you explore by phone, it takes about 4 weeks. Some banks will let you open the account with a pending EIN process, but most want the number in hand first.

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 mortgage statement showing that address. If you use a virtual office or mailbox service, bring the agreement. Some banks accept mailbox addresses; others do not. Ask when you call to confirm what the bank will accept.

What if I have a partner or co-owner?

Bring their government-issued ID and have them sign the account paperwork. The bank will ask whether both of you need signing authority or just one. If both of you can sign checks independently, tell the bank. If you need both signatures on every check, tell them that too—it changes how the account is set up.

How long does it take to open the account after I submit everything?

If you open in person with all documents, the account usually opens the same day or within 24 hours. If you open online, it typically takes 1 to 3 business days. The bank will tell you when checks and a debit card will arrive—usually 5 to 10 business days for checks and 7 to 14 days for a card.
