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 usually a deposit to open the account. The exact documents depend on your business structure — a sole proprietorship needs different paperwork than an LLC or corporation — and on which bank you choose.

Most banks will ask for your Employer Identification Number (EIN) if you have one, or your Social Security Number if you do not. You will also need a government-issued photo ID, your business license or registration documents, and a signed signature card authorizing who can access the account. Some banks require an initial deposit ranging from $25 to $500, though many have waived minimums in recent years.

Before you visit a bank, gather these documents in one place. Having them ready cuts the process from an hour to 20 minutes, and it signals to the bank that you are organized.

Key Takeaways

  • You will need your business registration documents, a government-issued photo ID, and either an EIN or Social Security Number — the specific documents vary by business structure.
  • Sole proprietorships often use the owner's Social Security Number instead of an EIN, while LLCs and corporations require an EIN from the IRS before opening an account.
  • Banks differ in their minimum deposit requirements, monthly fees, and whether they offer free checks or online tools — comparing three to five banks before opening saves money over time.
  • The account opens on the day you visit, but debit cards and checks typically arrive within five to ten business days.
  • You can open an account in person, by mail, or online depending on the bank, though in-person visits are fastest when you have all documents ready.

Sole proprietorships versus LLCs and corporations

A sole proprietorship is the simplest structure — you and your business are legally the same entity. You can open a business bank account using your Social Security Number instead of an EIN, though some banks will still ask for an EIN if you have one. You will need your business license (if your state or county requires one), your personal ID, and a signature card. The process is usually fastest for sole proprietors because there is less paperwork to verify.

An LLC or corporation is a separate legal entity, and banks treat it that way. You must have an EIN from the IRS before opening the account — you cannot use your Social Security Number alone. You will need your Articles of Organization (for an LLC) or Articles of Incorporation (for a corporation), your EIN letter from the IRS, a government-issued ID for the person opening the account, and a resolution or authorization document showing who is authorized to manage the account. If your business has multiple owners, the bank may ask for documentation of ownership percentages.

If you have not yet obtained an EIN, you can request one from the IRS online at irs.gov, by phone at 1-800-829-4933, or by mail using Form SS-4. Online requests are processed when ready; phone requests take about 15 minutes; mail requests take two to four weeks.

Comparing banks and account types

Business bank accounts are not standardized. Two banks in the same city may charge different monthly fees, offer different numbers of free transactions, and provide different online tools. Before opening an account, contact three to five banks — both large national banks and local or online-only banks — and ask about their business checking account options.

Ask each bank about: monthly maintenance fees (which range from $0 to $25 or more), the number of deposits and withdrawals included each month before fees explore, whether checks are free or cost per box, whether they offer a debit card, what their online banking platform includes, and whether they have a minimum balance requirement. Some banks waive monthly fees if you maintain a certain balance or set up direct deposit. Others charge per transaction after a certain number each month.

Online banks often have lower fees and no minimum balance, but they may not offer in-person service or the ability to deposit cash. Credit unions sometimes offer lower fees for members but may have membership requirements. Local banks may offer better customer service and faster problem resolution but sometimes charge higher fees. Write down the total annual cost for each bank based on your expected transaction volume, then choose the one that fits your actual business needs, not the one with the lowest advertised fee.

Opening the account in person, by mail, or online

In-person opening is fastest if you have all documents ready. You walk into a branch, speak with a banker, provide your documents, sign the signature card, make your initial deposit if required, and leave with temporary checks or a debit card. The account is active the same day. This route works best if you have questions about the account or if your documents are unusual in any way — a banker can tell you when ready whether something is missing.

Online opening is available from most national banks and many online-only banks. You upload photos of your documents, verify your identity (usually by answering security questions or confirming recent transactions), and sign electronically. The process takes 10 to 30 minutes. The account is usually approved within one to three business days, and you can begin using it online when ready, though physical checks and debit cards arrive separately.

Mail opening is rare but still offered by some banks. You send copies of your documents, a signed signature card, and your initial deposit by mail. The bank reviews everything and mails you confirmation, checks, and a debit card. This route takes two to four weeks and carries the risk of documents being lost in transit. Use it only if in-person and online options are not available to you.

What happens after you open the account

Your account is active when ready, but you cannot use it until you receive your debit card and checks. Debit cards typically arrive within five to ten business days; checks take one to two weeks. If you need to move money before then, ask the bank whether you can transfer funds online using your account number and routing number, or whether you can set up bill pay through their website.

Once your debit card arrives, test it at an ATM before relying on it for business expenses. Verify that your online banking login works and that you can see your account balance and transaction history. If you set up multiple authorized users, confirm that each person's card and access level are correct.

Keep your signature card and account opening documents in a safe place. You will need them if you ever need to add or remove authorized users, change the account type, or dispute a transaction. Some banks provide a welcome packet with this information; others require you to request it.

Authorized users and account access

When you open the account, you designate who can access it and what they can do. For a sole proprietorship, this is usually just you. For an LLC or corporation, you may want to add employees, partners, or accountants who need to deposit checks, pay bills, or review the account.

There are usually two levels of access: authorized signers (people who can sign checks and make large transactions) and authorized users (people who can deposit checks and access the account online but cannot sign checks). Ask your bank which level each person needs before you add them. Adding someone usually requires a signature card or authorization form and takes one to three business days to process.

You can remove an authorized user at any time by contacting the bank in person or by phone. If an employee leaves, remove their access when ready — do not wait for them to return their debit card.

Common mistakes to avoid

The most common mistake is opening a personal account instead of a business account. A personal account is cheaper and faster to open, but it does not separate your personal and business finances, which creates problems at tax time and can expose your personal assets if your business is sued. Always open a business account, even if your business is very small.

The second mistake is not comparing banks before opening. Many people open an account at the bank where they have a personal account, assuming it will be convenient. But business accounts have different fee structures than personal accounts, and the bank that is cheapest for personal checking may be expensive for business. Spend 30 minutes comparing before you decide.

The third mistake is not keeping your business and personal finances separate once the account is open. Deposit all business income into the business account and pay all business expenses from it. Do not mix personal and business money, even temporarily. This separation is what makes a business bank account worth opening in the first place.

Frequently Asked Questions

Can I open a business bank account without an EIN if I have an LLC?

No. LLCs are separate legal entities, and banks require an EIN to verify that the LLC exists and is registered with the IRS. You can request an EIN online at irs.gov and receive it when ready, or by phone in about 15 minutes. Once you have it, you can open the account the same day.

What if I do not have a business license yet?

Some states and counties do not require a business license for certain types of businesses, especially sole proprietorships. If your state does not require one, you can open an account with just your registration documents (like your LLC Articles of Organization) and your ID. Call your local business licensing office to confirm whether you need one before you visit the bank.

How long does it take to open an account?

In person, 20 to 45 minutes if you have all documents. Online, 10 to 30 minutes to complete the process, then one to three business days for approval. By mail, two to four weeks. You can use the account online when ready after approval, but physical checks and debit cards arrive separately within five to ten business days.

Do I need a minimum balance to keep the account open?

It depends on the bank and account type. Some banks waive monthly fees if you maintain a certain balance, usually $500 to $2,500. Others charge a monthly fee regardless of balance. Ask each bank about their minimum balance requirement before you open, and choose an account that matches your cash flow.

Can I change banks later if I do not like this one?

Yes. You can close the account at any time and open a new one at a different bank. The process is straightforward — just tell the bank you want to close the account, and they will tell you what to do with any remaining balance. Moving your direct deposits and automatic payments to the new account takes a few days, so plan ahead if you are switching.
