Documents you'll need to open a business checking account

Most banks will ask for your Employer Identification Number (EIN), a government-issued photo ID, and proof that your business exists. The exact list depends on your business structure — a sole proprietorship needs different paperwork than an LLC or corporation — and on the bank itself. Some banks ask for more; some ask for less. Call the bank's business services line before you go in, because showing up with the wrong documents wastes a trip.

The core documents almost every bank wants are your personal ID, your EIN (or Social Security number if you're a sole proprietor), and something showing your business name and address. Beyond that, the requirements split by what kind of business you are.

Key Takeaways

  • You will need a government-issued photo ID, your EIN or Social Security number, and proof your business exists — usually articles of incorporation, an LLC operating agreement, or a business license.
  • Sole proprietors often use their Social Security number instead of an EIN, but some banks require an EIN regardless of business structure.
  • Banks vary in what they ask for; calling ahead to confirm the exact list saves time and prevents rejected applications.
  • If your business is new and you don't have an EIN yet, you can apply for one online at the IRS website before opening the account.
  • Some banks ask for a business plan, proof of funding, or recent business tax returns if your company is more than a year old.

What sole proprietors need to bring

If you operate as a sole proprietor — meaning you're the only owner and haven't formed an LLC or corporation — you can use your Social Security number instead of an EIN. However, many banks now require an EIN even for sole proprietors, so check with your bank first. If you need an EIN, you can get one free from the IRS website in about 15 minutes.

Bring your personal government-issued ID (driver's license or passport), your Social Security number or EIN, and proof of your business address. Proof of address can be a utility bill, lease agreement, or mail from a government agency sent to your business location. Some banks also ask for a business license or DBA (Doing Business As) certificate if you operate under a name different from your own.

What LLC owners need to bring

For an LLC, bring your Articles of Organization — the document you filed with your state to form the LLC. This is the core document banks use to verify your business exists and is registered. You'll also need your EIN, a government-issued photo ID, and proof of your business address.

Some banks ask for an Operating Agreement, which is the internal document that outlines how your LLC is run. Not all states require you to file this with the state, so you may have created one yourself. If the bank asks for it and you don't have one, ask whether it's required or optional — many banks list it as optional but prefer to see it.

What corporation owners need to bring

For a C corporation or S corporation, bring your Articles of Incorporation, which is the document you filed with your state to form the corporation. You'll also need your EIN, a government-issued photo ID, and proof of your business address. Some banks ask for a Corporate Resolution — a document signed by the board of directors authorizing someone to open the account and manage it. If your bank requires this and you don't have one, they can usually provide a template.

A few banks also ask for a copy of your corporate bylaws, though this is less common. Call ahead to confirm whether your bank needs this before you apply.

Documents for partnerships and other structures

If you operate as a partnership, bring your Partnership Agreement and the document you filed with your state to register the partnership. You'll need an EIN, personal IDs for all partners who will have signing authority on the account, and proof of your business address.

For nonprofits, the requirements are different and usually include your Articles of Incorporation, your 501(c)(3) information letter from the IRS (or the equivalent for your nonprofit type), your EIN, and board resolutions authorizing the account. Nonprofits often face stricter requirements than for-profit businesses, so contact the bank's nonprofit services team if you have one.

What to do if your business is brand new

If you haven't received your EIN yet, you can get one immediately from the IRS website at irs.gov. The online application takes about 15 minutes, and you receive your EIN right away. Print the confirmation page — some banks will accept this as proof of your EIN while you wait for the official letter to arrive by mail.

If you haven't filed your Articles of Organization or Articles of Incorporation yet, do that first. You can't open a business account without proof that your business is registered with the state. The filing process varies by state but usually takes a few days to a few weeks. Some states offer expedited filing for an extra fee if you need it faster.

What banks ask for beyond the basics

Larger banks and some smaller ones ask for additional documents depending on your situation. If your business is more than a year old, they may ask for your most recent business tax return or a profit-and-loss statement. If you're opening the account with a large deposit, they may ask for proof of where the money came from — a personal bank statement, a loan document, or an investment agreement.

Some banks ask for a business plan or a description of what your business does, especially if it's in an industry they consider higher-risk (like cannabis, cryptocurrency, or financial services). A few banks ask for personal financial statements from the owners, particularly if the business is new and has no track record. These requests are less common but not unusual, so ask when you call to confirm what you need.

Frequently Asked Questions

Can I open a business account without an EIN?

Sole proprietors can sometimes use their Social Security number instead, but most banks now require an EIN regardless of business structure. Getting an EIN is free and takes 15 minutes online at irs.gov, so it's worth doing before you go to the bank.

What if I don't have my Articles of Organization yet?

File them with your state first — you can't open a business account without proof your business is registered. Most states process filings within a few days to a few weeks. Some offer expedited filing for a fee if you need it faster.

Do I need to bring all the owners to open the account?

Not necessarily. Usually one owner can open the account, but the bank will ask which owners have signing authority. If multiple owners will sign checks, bring all of them or bring a document showing who is authorized to sign.

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

Ask the bank whether the document is required or optional. Many banks list items like operating agreements or bylaws as "preferred" rather than required. If it's truly required and you don't have it, ask whether the bank can provide a template or accept an alternative.

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

Most banks open the account the same day or within one business day if all documents are in order. If the bank needs to verify anything or has questions, it may take a few days longer. Ask for a timeline when you submit your application.
