A business bank account is a separate account your business holds at a bank, distinct from your personal checking or savings account.
When you open a business bank account, the bank treats your business as its own entity for banking purposes. Money your customers pay you goes into this account. Money you spend on business expenses comes out of it. The bank issues statements showing all those transactions, and the account sits in your business's name—not yours personally.
This separation matters because it keeps your business finances visible and organized. When tax time comes, you have a clear record of what money moved in and out. If someone sues your business, the separation can protect your personal assets. And if you ever want to sell the business or bring in partners, a business bank account makes the financial picture much easier to understand.
Key Takeaways
- A business bank account holds money in your business's name, separate from your personal accounts, and creates a clear record for taxes and legal protection.
- Most banks require you to provide your business structure (sole proprietorship, LLC, corporation), an EIN or tax ID number, and identification before opening an account.
- Business accounts typically cost more than personal accounts—many charge monthly fees, per-check fees, or minimum balance requirements—though some banks waive fees for new businesses.
- Using a personal account for business money and a business account for personal expenses blurs the line between you and your business, which can create tax problems and weaken legal protection.
- You can open a business account online, by mail, or in person at a bank branch, and the process usually takes a few days to a week.
What happens when you open a business bank account
The bank will ask you to prove who you are and what your business is. You'll need a government-issued ID—a driver's license or passport. You'll also need to tell the bank your business structure: whether you're a sole proprietor, an LLC, a corporation, or a partnership. If your business has a name different from your legal name, bring a document that shows you own that business name—often called a DBA (doing business as) certificate, which you get from your county clerk.
The bank will ask for a tax ID number. If you're a sole proprietor with no employees, you can use your Social Security number. If you have employees or you've formed an LLC or corporation, you need an EIN (Employer Identification Number), which you get free from the IRS. You can apply for an EIN online at irs.gov and receive it immediately.
Some banks also ask for a business license, a recent business tax return, or proof of your business address. Requirements vary by bank and by the size of your business. Call ahead or check the bank's website to see what they need before you go in.
How much a business account costs
Business accounts are not free. Most banks charge a monthly maintenance fee—typically $10 to $30 per month, though some charge more. On top of that, many banks charge per transaction: $0.25 to $1.00 for each check you deposit, each wire transfer you send, or each ACH payment you make. Some accounts have a minimum balance requirement, meaning you have to keep a certain amount of money in the account at all times or pay a fee.
A few banks offer no-fee business accounts for new businesses or for businesses below a certain revenue threshold. Credit unions sometimes have lower fees than traditional banks. Online banks often charge less than brick-and-mortar banks. Compare what different banks charge before you open an account—the difference can add up to hundreds of dollars a year.
Some banks waive fees for the first few months or the first year. Ask whether that offer applies to you, and mark your calendar for when the fees start so you're not surprised.
Why mixing personal and business money creates problems
If you deposit customer payments into your personal checking account and pay business expenses from the same account, the IRS will have a harder time auditing your taxes because the money is all mixed together. You'll spend time sorting out which transactions were business and which were personal. If you get audited, the IRS may disallow deductions because you can't prove they were truly business expenses.
A separate business account also protects you legally. If your business is an LLC or a corporation, the law treats it as its own entity. That separation can shield your personal assets if someone sues your business or if your business owes money it can't pay. But that protection only works if you actually keep business and personal money separate. If you regularly move money between accounts or use the business account for personal expenses, a court may decide the separation is not real and hold you personally liable.
Using a personal account for business also makes it harder to get a business loan or line of credit later. Banks want to see a clear business financial history, and a business bank account provides that.
How to open a business bank account
You can open an account online, by mail, or in person at a bank branch. Online is usually fastest—many banks let you open an account in 10 to 15 minutes and start using it within a few days. By mail takes longer because you have to send documents back and forth. In person is useful if you have questions or if the bank needs to verify documents on the spot.
Start by gathering your documents: your ID, your EIN or Social Security number, your business license or DBA certificate if you have one, and proof of your business address (a utility bill or lease works). Then go to the bank's website or call to find out exactly what they need. Some banks have a checklist you can download.
When you open the account, the bank will give you a routing number and an account number. Write these down—you'll need them to set up direct deposit, to tell customers how to pay you, and to pay bills online. The bank will also issue you a debit card and checks if you want them, though many small businesses now use online payments instead.
What to do if you already mixed personal and business money
If you've been using a personal account for business, open a business account now and start moving forward. Going forward, deposit all business income into the business account and pay all business expenses from it. Don't panic about the past—you can still file your taxes correctly by going through your personal account statements and identifying which transactions were business-related.
If you're worried about an audit or if your business is large, talk to a tax professional or accountant. They can help you sort through old statements and make sure your tax returns are accurate. It's much cheaper to fix this now than to deal with it during an audit.
For future protection, especially if your business is an LLC or corporation, keep the business and personal accounts completely separate from this point forward. Don't transfer money between them except as a formal withdrawal or loan, and document those transfers.
Business accounts at different types of banks
Traditional banks like Chase, Bank of America, and Wells Fargo offer business accounts, but they often have higher fees and higher minimum balances. Credit unions typically charge less and may offer better customer service, though they may have fewer branches or ATMs. Online banks like Mercury, Brex, and Novo have lower fees and faster account opening, but they don't have physical branches if you need to deposit cash or speak to someone in person.
Some banks specialize in certain types of businesses. Brex, for example, focuses on startups and tech companies. Novo targets freelancers and small service businesses. Traditional banks are better if you need a business loan or a line of credit, because they have underwriting teams and established lending programs. Online banks are better if you want low fees and fast setup.
Consider what you actually need: Do you deposit cash regularly? Do you need a business loan soon? Do you want to minimize fees? Do you need customer support by phone? Your answers will point you toward the right bank.
Frequently Asked Questions
Do I need a business bank account if I'm a sole proprietor?
You don't legally have to, but you should. A business account keeps your finances organized for taxes and makes it easier to prove business expenses if you're audited. It also protects you if your business is sued, because it shows you kept business and personal money separate.
Can I use my Social Security number instead of an EIN?
Yes, if you're a sole proprietor with no employees. You can use your Social Security number as your tax ID. But if you have employees or you've formed an LLC or corporation, you need an EIN. You can get one free and instantly at irs.gov.
What if the bank asks for a business tax return and I'm brand new?
Tell the bank you're new and don't have a tax return yet. Many banks will open an account anyway, especially if you show them a business license or DBA certificate and proof of your business address. If one bank says no, try another—requirements vary.
Can I have multiple business bank accounts?
Yes. Some businesses open separate accounts for different purposes—one for operating expenses, one for payroll, one for a specific project. Each account costs money, so weigh the benefit against the fees. Most small businesses do fine with one account.
What if I close my business—what happens to the account?
Contact the bank and tell them you want to close the account. They'll ask you to withdraw or transfer any remaining money, pay any outstanding fees, and return your debit card and checks. The account will be closed within a few days to a week.
