What you'll need before you walk into the bank

Opening a business bank account requires documents that prove who you are, what your business is, and that you have the legal right to control the account. Most banks want to see your business formation paperwork, a government ID, and proof of your tax identification number. The exact list varies by bank and by the structure of your business — a sole proprietorship needs different paperwork than an LLC or corporation.

You cannot open an account without at least one owner or authorized representative present with a valid ID. Some banks let you start the process online, but they will ask you to come in or use a video call to verify your identity before the account goes live.

Key Takeaways

  • Bring a government-issued photo ID for each owner or authorized signer, even if only one person will open the account in person.
  • Your business formation documents — articles of incorporation, articles of organization, or a DBA certificate — prove your business exists and is legally registered.
  • An EIN (Employer Identification Number) from the IRS or a Social Security number serves as your business tax ID, and banks verify it before opening the account.
  • Proof of your business address, such as a utility bill or lease, is required by most banks to prevent fraud and meet federal banking rules.
  • Some banks ask for a business license or permit, depending on your industry and state; call ahead to confirm what your bank requires.

Government ID and ownership documentation

Bring a current, government-issued photo ID — a driver's license, passport, or state ID card. The name on the ID must match the name on your business formation documents. If you are opening the account as a sole proprietor using your own name, the ID alone is usually enough to prove ownership.

If your business is an LLC, corporation, or partnership, bring your articles of organization or articles of incorporation. These are the official documents you filed with your state's Secretary of State office when you registered the business. If you formed the business more than a few years ago and do not have the original, you can request a certified copy from your state's Secretary of State website — most states charge $5 to $25 for this.

If you operate under a name that is different from your legal name (a "doing business as" or DBA), bring the DBA certificate you filed with your county or state. Some banks will not open an account under a DBA name without this certificate.

Tax identification number and verification

The bank needs to verify your business tax ID before the account opens. If your business has employees or is structured as an LLC, S-corp, or C-corp, you need an EIN (Employer Identification Number) from the IRS. You can get an EIN for free at irs.gov by filling out Form SS-4 online — the IRS issues it immediately, and you can use the number the same day.

If you are a sole proprietor with no employees, you can use your Social Security number instead of an EIN. However, many sole proprietors get an EIN anyway to keep their personal and business finances separate on credit reports and tax filings.

Bring documentation showing your EIN or Social Security number. This can be the IRS confirmation letter you received when you applied for the EIN, a copy of your business tax return, or a letter from the IRS. If you are using your Social Security number, your ID is usually enough — the bank will verify it with the IRS during the account setup process.

Proof of business address

Banks are required by federal law to verify that your business address is real and that you control it. Bring a recent utility bill, lease agreement, or property tax statement showing your business address and your name or your business name. The document must be dated within the last 60 to 90 days — banks reject older bills.

If your business operates from your home, a utility bill in your name at that address works. If you rent office or retail space, bring a copy of your lease. If you use a virtual office or mail forwarding service, bring the agreement showing that service as your business address, though some banks will not accept this and may require a physical location.

Business license and industry-specific permits

Many states and cities require a business license or permit before you can legally operate. Some banks ask to see this before opening the account; others do not. Call the bank's business services line before you go in and ask whether they require a business license for your industry.

If your business is in a regulated field — food service, childcare, healthcare, alcohol sales, or financial services — the bank may ask for proof that you hold the necessary licenses or permits. You can get a business license from your city or county clerk's office, usually for $50 to $500 depending on your location and industry.

Additional documents some banks request

Depending on the bank and the size of your account, you may be asked for a business plan, recent tax returns, or a letter explaining the purpose of the account. Banks use these to assess risk and to comply with anti-money-laundering rules.

If you are opening the account as a representative of someone else's business (as a manager or employee), bring a letter from the owner authorizing you to open the account, signed and dated. Some banks require this letter to be notarized.

If the business is new and you have no tax returns yet, bring documentation of your startup costs, a business plan, or a personal financial statement. This helps the bank understand the source of the funds you will deposit.

What to bring in person versus what to prepare ahead

Gather and organize all documents before you go to the bank. Make copies of everything — keep the originals for your records. The bank will usually keep copies of your ID, formation documents, and address verification, so bring extras if you have them.

If you are opening the account online or by video call, you will need to upload images or PDFs of your documents. Make sure the images are clear, in color, and show the entire document. The bank will ask you to hold your ID up to the camera to verify it matches your face.

Bring a blank check or deposit slip if you have one, though the bank will provide these. Bring the names and Social Security numbers or EINs of all owners or authorized signers if more than one person will have access to the account.

Frequently Asked Questions

Do I need an EIN if I am a sole proprietor with no employees?

No, you can use your Social Security number instead. However, getting an EIN keeps your personal and business finances separate on credit reports and makes it easier to hire employees later without reapplying. An EIN is free and takes five minutes to get online.

What if I do not have my original articles of organization?

Contact your state's Secretary of State office and request a certified copy. Most states provide this online or by mail for a small fee ($5 to $25). The bank will accept a certified copy in place of the original.

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

Most banks will not open an account without proof that your business is legally registered. Register your business first with your state's Secretary of State office (for LLCs and corporations) or your county clerk (for DBAs). This usually takes one to two weeks.

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

Some banks accept a virtual office address or mail forwarding service, but many do not. Call ahead and ask. If the bank will not accept it, you can use your home address temporarily, or wait until you have secured a physical location.

Do I need to bring my business plan to open the account?

Most banks do not require a business plan. However, if your business is brand new and you have no tax returns or financial history, the bank may ask for one to understand where your startup funds came from and what the account will be used for.
