What you need before you walk in

A business bank account requires proof that your business exists as a legal entity, proof of your identity, and documentation of who controls the account. The exact documents depend on your business structure — sole proprietorship, LLC, corporation, or partnership — and the bank you choose. No two banks ask for identical paperwork, but the core pieces are always the same.

Start by gathering your Employer Identification Number (EIN), which the IRS issues to nearly all business structures except sole proprietorships operating under a personal name. You can obtain an EIN online at irs.gov in minutes, or by mail or phone if you prefer. If you are a sole proprietor using your Social Security number instead, bring that instead. You will also need a government-issued photo ID — a driver's license or passport — and your Social Security number or EIN.

The third piece is proof that your business is registered with your state. This is a Certificate of Good Standing for an LLC or corporation, or a DBA (Doing Business As) filing for a sole proprietorship. Your state's Secretary of State office issues these, usually for a small fee, and many now offer them online. Some banks will accept a business license from your city or county instead, but the state document is safer because it is the official record.

Key Takeaways

  • You will need an EIN (or your Social Security number if you are a sole proprietor), a government photo ID, and proof your business is registered with your state.
  • Different banks ask for different documents — some want articles of incorporation or an operating agreement, others do not — so call ahead and ask what your specific business structure needs.
  • Bring originals or certified copies of documents, not photocopies, because banks verify them against state records before opening the account.
  • The account usually opens the same day if you have all documents, though some banks send a confirmation letter and require a deposit before the account is fully active.
  • If you are opening the account as a representative of the business rather than the owner, bring a resolution or letter from the owner authorizing you to do so.

What documents each business structure needs

A sole proprietorship is the simplest. If you are operating under your own name, you need only your Social Security number, a photo ID, and proof of registration if your state or city requires a DBA filing. Many sole proprietors skip the DBA and operate under their personal name, which is legal in most states — in that case, bring your Social Security number and ID only.

An LLC requires your Articles of Organization (the document you filed with your state to create the LLC), your EIN, a photo ID, and your Social Security number. Some banks also ask for a copy of your operating agreement, which is the internal document that governs how the LLC operates. If you do not have a written operating agreement, tell the bank — many will not require one if you confirm you are the sole member.

A corporation needs your Articles of Incorporation, your EIN, a photo ID, and your Social Security number. Some banks ask for a corporate resolution — a document signed by the board of directors authorizing the account opening — but this is less common than it once was. Call the bank before you go and ask whether they require it. If they do, you can draft one yourself using a template or have your accountant prepare it.

A partnership requires your Partnership Agreement (the document that governs the partnership), your EIN, photo IDs and Social Security numbers for all partners, and proof of registration with your state. If one partner is opening the account on behalf of the others, bring a signed authorization from the other partners. Some banks require all partners to be present; others do not. Ask when you call.

The steps to open the account in person

Call the bank first. Do not assume all branches handle business accounts — some do not, and some require an appointment. Tell them your business structure and ask what documents they need. This call saves you a trip with incomplete paperwork. Ask also whether they require a minimum deposit to open the account, and whether that deposit must be in cash or can be a check.

Gather your documents in originals or certified copies. Banks will not accept photocopies because they verify documents against state records. If you ordered your Certificate of Good Standing or Articles of Organization online, print the official version from your state's website or the email confirmation — do not use a copy you made yourself. Bring your photo ID and your Social Security number or EIN.

Go to the branch with all documents and your initial deposit. The banker will review your documents, verify them against state records (this usually takes a few minutes), and ask you to sign signature cards and account agreements. The signature card is the bank's record of who is authorized to sign checks and withdraw money. If multiple people will use the account, all authorized signers must be present and sign the card.

The account usually opens the same day. The banker will give you temporary checks or a debit card, or both, depending on the bank. Some banks mail a confirmation letter and require you to make a deposit before the account is fully active — ask about this before you leave. Your routing number and account number appear on the temporary checks or in your online banking portal within hours.

Opening an account online or by mail

Some banks allow business account opening entirely online, though the process is less common than it is for personal accounts. You will upload photos of your documents (your ID, your EIN letter, your Articles of Organization or Certificate of Good Standing) and sign electronically. The bank verifies the documents and contacts you by phone or email if anything is unclear. This usually takes three to five business days.

Opening by mail is slower and requires more back-and-forth. You send originals or certified copies of your documents, along with a signed process form. The bank verifies them, then mails you signature cards to sign and return. Once they receive the signed cards, the account opens. This process typically takes two to three weeks. Use certified mail so you have proof the bank received your documents.

Online and mail opening work best if your business structure is straightforward — a sole proprietorship or single-member LLC. If you have multiple owners or partners, the bank usually requires at least one person to come in and sign in person, because the bank needs to verify identity and confirm that the person signing is actually authorized to open the account.

What happens after the account opens

Your account is active when ready, but you may not have full access to all features right away. Most banks issue a temporary debit card or temporary checks the same day. Permanent checks arrive by mail within one to two weeks. Your online banking access usually activates within 24 hours, and you can see your account number and routing number there even if your checks have not arrived.

Some banks place a hold on your initial deposit for a few business days, especially if you deposited a check. This is normal and does not mean there is a problem with your account. The hold protects the bank in case the check bounces. Once the hold lifts, the money is fully available.

Set up payroll and vendor payments as soon as the account is open. If you plan to use direct deposit for employee paychecks, you will need your routing number and account number, which the bank provides on your first statement or in your online portal. If you plan to pay vendors by check, order permanent checks as soon as possible — temporary checks work, but vendors sometimes hesitate to accept them.

Common reasons banks reject applications

Banks decline business accounts most often because the applicant's documents do not match state records. If your Articles of Organization say your LLC is named "Smith Consulting LLC" but you are trying to open an account under "Smith Consulting", the bank will ask you to clarify. The name must match exactly. If you have changed your business name, you need an amendment filed with your state, not just a DBA.

A second common reason is that the person opening the account is not authorized to do so. If you are opening the account as an employee or manager rather than the owner, bring a signed letter or resolution from the owner authorizing you. Some banks require this even if you are the sole owner, because they want written proof that you are acting on behalf of the business.

Banks also decline accounts when the applicant has a history of fraud or financial crime. This is rare for first-time business owners, but if you have a criminal record related to fraud or money laundering, disclose it to the bank before you explore. Some banks will still open the account; others will not. Being upfront is better than having the process rejected after the bank discovers it.

Frequently Asked Questions

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

No. Sole proprietors can use their Social Security number instead. However, getting an EIN is free and takes minutes online, and many sole proprietors get one anyway because it keeps their business finances separate from their personal finances on credit reports and with vendors.

Can I open a business account without going to the bank in person?

Some banks allow it, but most require at least one authorized person to come in and sign in person. Call your bank and ask whether they offer fully online opening for your business structure. If they do not, you will need to visit a branch at least once.

How long does it take to open a business account?

Same-day if you go in person with all documents. Three to five business days if you open online. Two to three weeks if you open by mail. The timeline depends on how quickly the bank verifies your documents against state records and how quickly you return signed paperwork.

What if I do not have a Certificate of Good Standing yet?

Order it from your state's Secretary of State office before you go to the bank. Most states issue them online within minutes or by mail within a few days. Some banks will accept a copy of your filed Articles of Organization instead, but the Certificate of Good Standing is the official proof and is safer.

Do all owners have to be present when I open the account?

It depends on the bank and your business structure. Call ahead and ask. Some banks require all owners to sign the signature card in person; others allow one owner to open the account and add other signers later. If you cannot get all owners present, ask the bank what authorization documents they need instead.
