What you need before you walk into a bank

You cannot open an LLC bank account without an Employer Identification Number (EIN) from the IRS. This is a nine-digit number that works like a Social Security number for your business. You get it free from the IRS website (irs.gov) by filling out Form SS-4, either online or by mail. Online approval takes minutes; by mail it takes two to four weeks. You do not need to wait for your LLC formation documents to be filed with your state — you can apply for an EIN as soon as you have decided on your business name.

You will also need your LLC formation documents — the Articles of Organization or Certificate of Formation filed with your state. Bring the official copy, not a photocopy. Some banks will accept a certified copy from your state's Secretary of State office; others want the original. Call the bank before you go and ask which one they need. You will also need a government-issued ID (driver's license or passport) and your Social Security number.

A few banks ask for an Operating Agreement, which is the internal rulebook for your LLC. This is not filed with the state — it is a document you create yourself that outlines how decisions get made and who owns what. You can find templates online or write one yourself. Not every bank requires it, but having one shows you are organized and makes the process faster.

Key Takeaways

  • You need an EIN from the IRS, your LLC formation documents from your state, and a government ID before any bank will open an account.
  • You can get an EIN online in minutes at irs.gov using Form SS-4, and you do not have to wait for your state filing to be complete.
  • Different banks ask for different documents — call ahead to confirm whether they want an original or certified copy of your Articles of Organization.
  • Some banks require an Operating Agreement; most do not, but having one speeds up the process and shows the bank your LLC is legitimate.
  • Bring multiple forms of ID and be prepared to answer questions about the nature of your business and expected monthly deposits.

Getting your EIN before you go to the bank

The fastest way is to apply online at irs.gov/ein. Go to the IRS website, find the EIN application tool, and answer questions about your business name, address, and structure. You will confirm that you are the owner or authorized representative, and the system will issue your EIN on the spot. Write it down immediately — the IRS does not email it to you, and you will need it to give to the bank.

If you cannot apply online, you can mail Form SS-4 to the IRS address listed on the form itself. Processing takes two to four weeks. You can also call the IRS Business and Specialty Tax Line at 1-800-829-4933, but wait times are long and you will need to answer the same questions over the phone. For most people, online is the only practical option.

Once you have your EIN, you do not need to do anything else with the IRS before opening the bank account. The EIN is yours to use immediately.

Choosing a bank and what to bring

Most national banks (Chase, Bank of America, Wells Fargo, Citibank) and regional banks offer LLC business accounts. Credit unions also offer them, sometimes with lower fees. Before you choose, call or visit the bank's website and confirm they have a business account product for LLCs, and ask what documents they need. Some banks have different requirements depending on whether the LLC is single-member (one owner) or multi-member (more than one owner).

Bring these documents in person: your EIN letter or a printout showing your EIN, your original or certified Articles of Organization (ask the bank which), your government-issued ID, and your Social Security number. If the bank asks for an Operating Agreement, bring that too. Bring a blank check or deposit slip if you have one, though the bank will provide these. Some banks also ask for a recent utility bill or lease to verify your business address, so bring that if you have it.

The banker will ask you questions about your business — what you do, how much money you expect to deposit each month, whether you will be writing checks or receiving wire transfers, and whether you need a business credit card. Answer honestly. These questions help the bank set up your account correctly and flag any red flags early.

What happens during the account opening

The banker will review your documents, verify your EIN with the IRS (this takes a few minutes), and confirm that your LLC name matches your Articles of Organization. They will ask you to sign signature cards and account agreements. Read these before you sign — they spell out the bank's fees, overdraft policies, and what happens if you do not maintain a minimum balance.

Some banks open the account on the spot and give you a temporary debit card and checks. Others mail your debit card and checks within five to ten business days. Ask the banker what to expect. If you need to deposit money right away, ask whether you can do it the same day or whether you have to wait for the account to be fully activated.

The banker will also ask whether you want online banking and mobile access. Say yes — you will need these to check your balance, transfer money, and pay bills. The bank will set up a username and password before you leave, or send you a link to create one online.

After you leave the bank

Your account is usually active within one business day. You can start depositing money and writing checks as soon as the banker tells you the account is open. If the bank mailed your debit card and checks, they will arrive within five to ten business days. In the meantime, you can deposit money using mobile deposit (photograph a check with your phone) or by visiting the bank in person.

Set up online bill pay if you plan to pay vendors or contractors by bank transfer. Most banks offer this free. You can also set up automatic transfers to move money between accounts if you have a personal account at the same bank.

Keep your EIN letter and a copy of your Articles of Organization in a safe place. You will need them if you ever have to prove your business exists — for a loan, a vendor account, or an audit.

Common reasons banks reject LLC accounts

Banks sometimes refuse to open an account if your EIN does not match your LLC name, if your Articles of Organization show a different owner than the person applying, or if your business address is a mailbox rather than a physical location. Some banks also have policies against certain types of businesses (cannabis, cryptocurrency, high-risk industries). Call the bank and ask about their policies before you go.

If a bank rejects you, try another bank. Different banks have different rules. Credit unions are sometimes more flexible than national chains. If you are rejected by multiple banks, the issue is usually that your EIN or LLC documents do not match what you told the bank. Go back to the IRS or your state's Secretary of State office and confirm everything is correct.

Single-member versus multi-member LLC accounts

If your LLC has one owner (you), the bank may ask whether you want to be taxed as a sole proprietor or as a corporation. This is a tax question, not a banking question — it does not change how the account works. Most single-member LLCs are taxed as sole proprietorships by default, and the banker will set up the account that way unless you tell them otherwise. If you have filed Form 8832 with the IRS to be taxed as a corporation, bring a copy and tell the banker.

If your LLC has more than one owner, the bank will ask for the names and Social Security numbers of all owners. They may also ask for a copy of your Operating Agreement to confirm who has authority to sign checks and make transfers. This takes a little longer, but the process is the same.

Frequently Asked Questions

Do I need to have my LLC officially filed with the state before I open a bank account?

Yes. The bank needs to see your filed Articles of Organization or Certificate of Formation. You can get your EIN before your state filing is complete, but you cannot open the account until your state has processed your LLC formation and issued your official documents.

Can I use my personal Social Security number instead of an EIN?

Some banks allow single-member LLCs to use the owner's Social Security number instead of an EIN, but most require an EIN. It is easier to just get the EIN — it takes five minutes online and is free. Having an EIN also separates your personal finances from your business finances, which is important for taxes and liability protection.

What if I do not have a business address yet?

You need a physical address for your LLC — a mailbox does not count. This can be your home address, a rented office, or a virtual office address. Some banks will not accept a home address if your LLC is in a different state, so call ahead and ask. If you are using a virtual office, bring a letter from the virtual office company confirming your address.

How long does it take to open an LLC bank account?

If you have all your documents, the account opens the same day or within one business day. Debit cards and checks arrive within five to ten business days. The longest part is usually getting your EIN and filing your LLC with the state, which can take two to four weeks depending on the state.

Do I need a business license before I open a bank account?

No. A business license is separate from an LLC and is not required to open a bank account. Some cities and states require a business license depending on what you do, but the bank does not check for this. You can get a business license after you open the account if you need one.
