The documents you need depend on your business structure, but most banks want proof of identity, proof of the business itself, and proof of who owns it

Every bank has a slightly different checklist, but the core documents fall into three categories: who you are, what your business is, and who controls the money. A sole proprietorship needs fewer documents than an LLC or corporation because there is less legal structure to verify. Before you visit a bank or explore online, call the specific branch or check their website for their exact list — some banks ask for things others do not, and some have different requirements for in-person versus online accounts.

Bring originals or certified copies when you can. Banks will not accept photocopies of government ID or tax documents in most cases. If you are opening the account online, you will upload images of documents, and the bank will verify them electronically — this usually takes a few business days longer than walking in with the originals.

Key Takeaways

  • You will need a government-issued photo ID for yourself and any co-owner or authorized signer, plus proof of your Social Security number or EIN.
  • Your business structure determines what else you need: sole proprietors may only need a DBA filing or business license, while LLCs and corporations need formation documents from your state.
  • Banks verify your business address with a utility bill, lease, or mortgage statement dated within the last 60 to 90 days — a PO box does not count.
  • If you are opening an account for a business that is fewer than six months old, some banks ask for a business plan or proof of funding to prevent fraud.
  • Call your bank before you go in or explore online, because requirements vary by institution and by account type.

Personal identification documents for you and any co-owners

Bring a current government-issued photo ID — a driver's license, passport, or state ID card. The bank will photocopy it and verify it matches the name on the account process. If you are opening a joint account or if someone else will be an authorized signer, that person needs to bring their own photo ID as well.

You will also need to provide your Social Security number. The bank uses this to run a background check and to report the account to the IRS. If your business has an Employer Identification Number (EIN) instead of or in addition to your SSN, bring that too — you can find it on your IRS correspondence or by logging into your IRS account online.

Proof of your business structure and ownership

What you bring here depends on how your business is legally set up. A sole proprietorship usually needs only a DBA (Doing Business As) certificate filed with your county or state, or a business license from your city. Some banks will open an account with just your personal ID and a signed process if you are operating under your own name.

An LLC or corporation needs your Articles of Organization or Articles of Incorporation — the document you filed with your state when you created the business. Bring the certified copy you received from the state, not a photocopy. The bank will verify the filing date and the registered agent to confirm the business is real and legally active.

If you formed your business more than a few months ago, the bank may ask for an EIN letter from the IRS confirming your tax ID number. You can request this free from the IRS by logging into your online account or calling 1-800-829-4933. It arrives by mail in about two weeks, or you can print it when ready if you created your EIN online.

Proof of your business address

Banks need to verify that your business address is real and that you control it. Bring a recent utility bill, lease agreement, or mortgage statement in the business name or your personal name, dated within the last 60 to 90 days. A cell phone bill, credit card statement, or insurance bill also works if it shows your address.

If your business operates from your home, a utility bill or mortgage statement with your home address is fine. If you rent a commercial space, bring the lease. If you use a mailbox service or coworking space, bring the agreement showing your address there — but note that some banks do not accept PO boxes or virtual addresses for the primary business address, though they may accept them for a mailing address.

Documents for new businesses or high-risk situations

If your business is fewer than six months old, some banks ask for additional proof that the business is legitimate and funded. This might be a business plan, a copy of your business license, proof of initial funding (a bank statement showing a deposit or a loan document), or a letter from a business advisor or accountant confirming the business exists.

Banks also run background checks on business owners to screen for fraud and money-laundering risk. If you have a criminal history or prior banking issues, the bank may ask for more documentation or may decline to open the account. There is no way to know this in advance — it depends on the bank's internal policies and what shows up in their screening.

What to bring if someone else will sign checks or access the account

If you are naming an authorized signer — someone who can withdraw money, write checks, or make transfers on behalf of the business — that person needs to come in with you or provide their own documents. They will need a government photo ID and their Social Security number. The bank will run a background check on them as well.

Some banks require authorized signers to sign the account agreement in person at the branch. Others allow you to add signers after the account is open, which can be faster if you are in a hurry. Ask the bank whether signers can be added later or whether everyone needs to be present at opening.

Online account opening versus in-person

If you open the account online, you will upload images of your documents instead of bringing originals. Take clear photos of both sides of your ID, your business formation documents, and your address proof. The bank will verify these electronically, which usually takes two to five business days. Some banks ask you to verify your identity through a video call with a representative before they set up the account.

In-person opening is usually faster — you can walk out with a debit card and checks the same day if everything is in order. Online opening is more convenient if the bank does not have a branch near you, but it takes longer and gives you less chance to ask questions about account features or fees before you commit.

Frequently Asked Questions

Do I need an EIN to open a business bank account?

Not always. Sole proprietors can use their Social Security number instead. LLCs and corporations typically need an EIN, but some banks will open the account and let you add the EIN later if you have applied for one but have not received it yet. Call your bank to ask whether you can open now and provide the EIN within 30 days.

What if I do not have a physical business address yet?

Some banks accept a home address or a coworking space address. A few accept UPS Store or mailbox service addresses for the mailing address but require a physical street address for the business location. If you do not have a permanent address, ask the bank whether you can use your home address temporarily and update it later, or whether they offer virtual business addresses.

Can I open a business account if my business is not registered with the state yet?

It depends on the bank. Some will open an account for a sole proprietorship with just a business license or DBA filing. Others want to see Articles of Organization or Incorporation. Call ahead and ask what documents they need for your specific business type — do not assume you are disqualified until you ask.

Do I need to bring my business plan or financial statements?

Most banks do not require these for account opening. Some ask for them if your business is very new (under three months old) or if you are requesting a business line of credit at the same time. A one-page business plan or a straightforward statement of how you will fund the business is usually enough if they ask.

What happens if the bank rejects my process?

Banks must tell you why they declined, usually in writing within a few days. Common reasons are a failed background check, an address that could not be verified, or a mismatch between your ID and your process. If you disagree with the reason, you can ask the bank to reconsider or try a different bank — different institutions have different risk thresholds.
