What you need before you walk in
A business bank account separates your personal money from your business money. Banks need proof that your business exists and that you have the right to open an account for it. What you bring depends on what kind of business you run.
If you are a sole proprietor (you own the business by yourself with no formal structure), you will need a government-issued ID, your Social Security number, and proof of your business address — a lease, utility bill, or mail from a government agency all work. Some banks also ask for a business license, though not all states require one.
If you have formed an LLC, S-corp, or C-corp, bring your Articles of Organization or Articles of Incorporation — the document you filed with your state to create the legal entity. You will also need an Employer Identification Number (EIN), which you get free from the IRS. If you do not have one yet, you can apply online at irs.gov and receive it immediately.
Partnerships need the same formation documents plus identification for each partner who will have authority over the account. A sole proprietor can sometimes use just their Social Security number instead of an EIN, but many banks prefer an EIN for any business structure.
Key Takeaways
- Sole proprietors need a government ID, Social Security number, and proof of business address; an EIN is optional but many banks prefer it.
- LLCs, S-corps, and C-corps must bring their formation documents (Articles of Organization or Incorporation) and an EIN from the IRS.
- Partnerships require formation documents and identification for each partner with signing authority on the account.
- Most banks verify your information against their fraud database before opening the account, which usually takes one to three business days.
- You can open an account in person, by mail, or online depending on the bank, though in-person is fastest if you have all documents ready.
Where to open the account
You can open a business account at a traditional bank, a credit union, or an online bank. Each has different requirements and different speeds.
Traditional banks (Chase, Bank of America, Wells Fargo, and regional banks) usually require you to come in person with your documents. They verify your identity on the spot and can open the account the same day. Some branches will also help you understand what account type fits your business — whether you need a checking account, a savings account, or both.
Credit unions are member-owned and often have lower fees than traditional banks. You must become a member first, which usually means living or working in a certain area or belonging to a certain group. Once you are a member, opening a business account follows the same process as a traditional bank.
Online banks (Brex, Mercury, Wise, and others) let you open an account entirely through their website or app. You upload photos of your documents instead of showing them in person. This is faster — sometimes just a few hours — but the bank cannot answer questions about your specific situation, and some online banks have stricter rules about what kinds of businesses they accept.
The documents the bank will ask you to sign
When you open the account, the bank will give you a signature card or an account agreement. This is a form that says you understand the account rules and that you authorize the bank to hold your money and process your transactions.
Read the fee schedule before you sign. This document lists what the bank charges for different services — monthly maintenance fees, per-check fees, overdraft fees, wire transfer fees, and fees for closing the account early. Fees vary widely between banks. A bank with no monthly fee might charge $1.50 per check, while another charges $15 a month but includes unlimited checks.
If you have more than one person who will move money in and out of the account, the bank will ask you to list them and decide who can sign checks or authorize transfers. Some accounts require two signatures on every check; others let any authorized person sign alone. This is a security choice you make when you open the account.
The bank will also ask about the source of your opening deposit. This is standard anti-money-laundering procedure. You do not need a large opening deposit — many business accounts have no minimum — but the bank wants to know where the money came from.
How the bank verifies your information
After you submit your documents, the bank runs your name, address, and business information through fraud-detection databases. This is called Know Your Customer (KYC) verification. The bank is checking that you are who you say you are and that your business is not on any government watchlist.
This process usually takes one to three business days. During this time, the bank may call you to confirm details or ask follow-up questions about your business. Answer honestly and quickly — delays in responding can slow down account opening.
If the bank cannot verify your information, it will tell you why and ask for additional documents. Common reasons include a mismatch between your ID and your business address, or a name that appears on a government list. These issues are usually resolved by providing a recent utility bill, a lease, or a letter from a government agency.
What happens after the account opens
Once the bank approves you, it will give you a debit card, checks, and online banking access. The debit card usually arrives in three to seven business days. Checks take longer — typically one to two weeks — because they are printed to order.
You can start using the account immediately through online banking and wire transfers, even if your physical cards and checks have not arrived yet. The bank will give you a routing number and account number on the day the account opens, and you can use these to receive deposits or set up automatic payments.
Set up online banking right away. This lets you see your balance, download statements, and set up alerts if your balance drops below a certain amount. Most banks let you do this on the same day the account opens.
Different account types for different business needs
Most banks offer a basic business checking account, which is what most small businesses use. This account lets you write checks, use a debit card, and receive deposits. Monthly fees range from zero to $25 depending on the bank and how much money you keep in the account.
Some banks also offer a business savings account, which earns a small amount of interest on your balance. Interest rates are low — usually between 0.01% and 0.5% per year — but if you keep a large cash reserve, it adds up. You cannot write checks from a savings account, so most businesses use this as a separate place to hold money they are not spending right away.
If you take credit card payments from customers, ask about a merchant services account. This is not a bank account itself, but a service that lets you accept Visa, Mastercard, and other cards. The bank charges a percentage of each transaction — usually 2% to 3% — and deposits the money into your checking account a day or two later.
If you need to borrow money, some banks offer business lines of credit or business loans. These are separate products, but the bank may offer you a better rate if you already have a checking account with them.
Why banks ask certain questions about your business
When you open the account, the bank will ask what your business does, how much money you expect to move through the account each month, and whether you will be receiving cash deposits. These questions are not about whether you are a good person — they are about risk and regulation.
Banks are required by federal law to report suspicious activity. If your account shows patterns that do not match what you said your business does — for example, you said you run a consulting firm but you are depositing thousands in cash every day — the bank has to investigate and may file a report with the government.
Answer these questions truthfully. If your business changes later — you start accepting cash, or your monthly volume doubles — tell the bank. This prevents your account from being frozen while the bank investigates.
Frequently Asked Questions
Can I open a business account if my business is not registered with the state?
Yes, if you are a sole proprietor. You do not have to register a sole proprietorship in most states. However, some banks prefer to see a business license or a DBA (Doing Business As) filing, which costs $50 to $200 and takes a few days. If a bank turns you down without registration, filing a DBA usually solves it.
How much money do I need to open a business account?
Most banks have no minimum opening deposit. Some require $100 to $500. Check the bank's website or call ahead to ask. If you cannot meet a minimum, choose a bank that does not have one.
What if I do not have an EIN yet?
You can get one free from the IRS at irs.gov in about 15 minutes. If you are opening an account in person, you can apply for an EIN online before you go to the bank. Some banks will open an account using your Social Security number temporarily and let you add the EIN later, but this is slower.
Can I open a business account online if I am a partnership?
Most online banks require all partners to verify their identity, which is harder to do remotely. Traditional banks and credit unions are usually better for partnerships because you can bring all partners in person and complete everything in one visit.
How long does it take to get checks after I open the account?
Checks are printed to order and usually arrive in one to two weeks. You can order them through the bank's website or by phone. Some banks charge $10 to $30 per box of checks; others include them free. You can start using the account through online banking and transfers before your checks arrive.
