The documents you need before you walk in

Most banks want the same core set of documents: your business registration paperwork, a government-issued ID, and proof of your address. The exact list depends on your business structure and the bank, but you will not be turned away for missing something minor — the bank will tell you what else they need before you leave.

If you are a sole proprietor, bring your Social Security number, a driver's license or passport, and a recent utility bill or lease showing your home address. If you registered a business name with your state (a DBA, or "doing business as"), bring that certificate. If you have not registered anything yet, many banks will still open an account — they just need your personal ID and Social Security number, and they will ask you to register the name later.

For an LLC or corporation, bring the Articles of Organization or Articles of Incorporation — the document you filed with your state when you created the business. Bring a copy of your EIN letter from the IRS (the letter that assigned your business its tax ID number). If you do not have an EIN yet, the bank can often help you get one, or you can get one free from the IRS website before you go. Bring your personal ID and proof of address as well.

Key Takeaways

  • Sole proprietors need a government ID, Social Security number, and proof of address; a registered business name is helpful but not always required to open the account.
  • LLCs and corporations need the state filing document (Articles of Organization or Incorporation) and an EIN letter from the IRS, plus the owner's personal ID.
  • Proof of address can be a utility bill, lease, mortgage statement, or recent bank statement in your name at your current address.
  • Different banks have different secondary requirements — some ask for a business plan or recent tax returns, but most do not require these to open a basic account.
  • If you do not have all documents ready, call the bank first to ask what they specifically need rather than showing up unprepared.

Why banks ask for these documents

Banks are required by federal law to verify who owns the business and where the owner lives. This is part of anti-money-laundering rules called Know Your Customer (KYC) compliance. The bank needs to confirm that you are not opening the account under a false identity or on behalf of someone else.

For LLCs and corporations, the bank also needs proof that the business actually exists as a legal entity. The Articles of Organization or Incorporation show that you filed the paperwork with your state and that the business is real. The EIN letter proves the IRS recognizes the business as a separate tax entity.

Documents that vary by bank and business type

Some banks ask for a business plan, especially if you are requesting a business line of credit or a larger deposit account. Others ask for recent tax returns — usually the last two years — if you have been in business for more than a year. A few banks ask for a business license, though this is less common and depends on your industry.

If you are opening an account for a nonprofit, a partnership, or a trust, the bank will ask for different paperwork. A nonprofit needs its IRS information letter (the letter that confirms the organization is tax-exempt). A partnership needs the partnership agreement. A trust needs the trust document itself. Call ahead and ask what your specific structure requires.

Some banks also ask for a voided check or deposit slip to verify the account details, though most now skip this step. A few still ask for a business address that is different from your home address, though many banks now accept a home-based business address.

How to get documents you do not have yet

If you registered your business with your state but lost the certificate, you can request a certified copy from your state's Secretary of State office. Most states let you order this online for a small fee (usually $5 to $25) and will email or mail it to you within a few days.

If you do not have an EIN yet, you can get one free from the IRS. Go to irs.gov, search for "EIN", and follow the link to explore online. The IRS will issue your EIN when ready and email you a confirmation. You can print that confirmation and bring it to the bank — it counts as your EIN letter. If you explore by mail or phone, the process takes longer, so explore online if you can.

If you do not have a government-issued ID, you will need to get one before opening the account. A driver's license, passport, or state ID card all work. This is non-negotiable — banks cannot open an account without it.

What happens during the account opening appointment

Bring originals of all documents, not copies. The bank will look at them, verify the information, and usually make copies for their file. The process typically takes 15 to 30 minutes. The banker will ask you questions about the business — what it does, how much money you expect to move through the account, whether you will be depositing checks or using wire transfers — to set up the right account type for you.

You will also choose whether you want a debit card, checks, online banking, and mobile app access. Most of these are free or included with the account. You will set up a username and password for online banking before you leave, or the bank will email you a link to do it later.

If the bank needs additional documents, they will tell you before you leave and give you a important date — usually 10 to 30 days — to send them in. Your account will usually open when ready, even if you are still gathering secondary documents.

What the bank will not ask for

The bank will not ask for your personal tax returns unless you are also requesting a business loan or line of credit. They will not ask for your personal credit score or run a personal credit check just to open a deposit account. They will not ask for a business plan unless you are requesting financing.

If a bank asks for your personal Social Security number and then also asks for your business's Social Security number, that is normal — they are two different things. Your personal SSN identifies you; your business's EIN identifies the business itself. Both are required for an LLC or corporation.

Frequently Asked Questions

Can I open a business account without registering my business first?

Yes. Many banks will open an account for a sole proprietor using just your personal ID and Social Security number. You can register the business name later. However, if you have already registered the business, bring that certificate — it makes the process faster and clearer.

Do I need an EIN if I am a sole proprietor?

No. A sole proprietor can use their personal Social Security number instead. However, getting an EIN is free and takes five minutes online, and some banks prefer it because it keeps your personal and business finances more clearly separated.

What if I do not have proof of my current address?

A utility bill, lease agreement, mortgage statement, or recent bank statement all work. If you just moved and do not have anything in your name yet, ask the bank what they accept — some will take a signed lease or a letter from your landlord. Call before you go in so you know what to bring.

Can someone else open the account on behalf of the business?

Not usually. The bank needs to verify the owner's identity in person. If you are the owner, you need to be there. If the business has multiple owners, the bank may require all owners to sign the paperwork, though some banks let one owner open the account and add others later.

How long does it take to open an account?

The appointment itself takes 15 to 30 minutes. The account is usually active the same day or the next business day. If the bank needs additional documents, they may put a hold on certain features (like wire transfers) until those documents arrive, but your basic deposit account will work when ready.
