Your business needs its own bank account
How to choose one, what it should cost and what to bring when you open it.
A business bank account is the foundation of clean books, separate credit and a liability shield that holds up when it matters.
The first financial step after forming a business is opening an account in the business’s name. It sounds basic, yet many owners run business money through a personal account for months. That mixing, called commingling, makes taxes harder, hides how the business is really doing and can weaken the liability protection an LLC or corporation is supposed to provide.
The Federal Reserve’s 2025 Small Business Credit Survey shows how common mixing still is. Among firms that regularly use credit cards, 58% use only a business card, 8% use only a personal card and 34% use both.

Why a separate business bank account matters
- Liability protection. Courts can disregard an LLC or corporation, sometimes called piercing the corporate veil, when owners treat company money as their own.
- Cleaner taxes. The IRS expects records that support every deduction. One account for business only makes that record automatic.
- Business credit. Lenders and bureaus look for a business account with steady deposits. It is a building block of business credit.
- A real picture of profit. When only business money moves through the account, your bank statement becomes a quick check on cash flow.
Where to bank: four types of institutions
Small businesses bank with large national banks, community banks, credit unions and online banks. Each has strengths, and many owners use two: one for daily operations and one for savings or lending.
Business bank options compared
| Large bank | Community bank | Credit union | Online bank | |
|---|---|---|---|---|
| Branches and ATMs | Many, nationwide | Local | Local plus shared networks | None or few |
| Monthly fees | Often waived above a balance | Often lower | Often lowest | Often none |
| Cash deposits | Easy | Easy | Easy | Limited or through retail partners |
| Lending decisions | Standardized, often score-driven | Local, relationship-based | Local, member-based | Limited lending |
| Deposit insurance | FDIC, $250,000 | FDIC, $250,000 | NCUA, $250,000 | FDIC through a partner bank |
| Best for | Multi-location, merchant services | Loans and local knowledge | Low fees, small accounts | Low-cash, online businesses |
Your bank is also often your first lender. In the 2025 survey, applicants at small banks were the most likely to be fully approved for a loan, line of credit or cash advance:

Know your deposit insurance limits
The Federal Deposit Insurance Corporation (FDIC) insures deposits at member banks up to $250,000 per depositor, per insured bank, for each account ownership category. The National Credit Union Administration (NCUA) provides the same $250,000 coverage at federally insured credit unions. Accounts owned by your LLC or corporation are insured separately from your personal accounts at the same bank.
If your business routinely holds more than $250,000, ask your bank about spreading deposits across banks through an insured cash sweep program, or holding part of the reserve in U.S. Treasury bills. Our guide to business savings covers where to keep a cash reserve.
Fees and features to compare
- Monthly maintenance fee and the balance needed to waive it.
- Included transactions per month, and the charge for each one over the limit.
- Cash deposit limits, important for restaurants, salons and retail.
- Wire and ACH costs for paying vendors and receiving customer payments.
- Mobile check deposit limits and how fast funds are available.
- Accounting integration with QuickBooks, Xero or your bookkeeping software.
- Fraud tools such as Positive Pay, which flags checks you did not issue.
- Merchant services and lending, if you want card processing, a line of credit or an SBA loan from the same bank.
What you need to open a business bank account
Bring these documents
- Employer Identification Number (EIN)Sole proprietors without employees can sometimes use a Social Security number, but an EIN keeps your personal number off business records.
- Formation documentsArticles of Organization for an LLC, Articles of Incorporation for a corporation, or a filed fictitious business name statement for a sole proprietor using a trade name.
- Ownership and control detailsUnder federal customer due diligence rules, banks identify each person who owns 25% or more of the company and one person who controls it.
- Operating agreement or bylawsBanks use it to confirm who can sign and open accounts.
- Government-issued photo IDFor every signer on the account.
- Business license and opening depositSome banks ask for a city or county license and a minimum first deposit.
Ask local community banks and credit unions what they offer small businesses before you choose. Many pair a free or low-fee account with a banker who knows the region, which helps when you apply for your first line of credit or SBA loan.
Set it up for good habits
Open a business checking account for daily operations and a linked business savings account for your reserve and tax money. Pay yourself by transfer, not by spending from the business account. Connect the accounts to your bookkeeping software from day one, and reconcile every month. Those habits make your profit and loss statement and balance sheet easy to produce when a lender asks.
Questions to ask before you open an account
- What is the monthly fee, and exactly what balance or activity waives it?
- How many transactions, deposits and cash deposits are included each month?
- How quickly are mobile and branch deposits available to spend?
- What do incoming and outgoing wires and ACH transfers cost?
- Can I add employees with limited permissions, such as view-only or bill pay without transfers?
- Which accounting software does the bank connect with?
- What fraud protections are included, and what is my liability for unauthorized transactions?
- Does the bank offer small business lines of credit or SBA loans, and how do current customers qualify?
Common mistakes
- Choosing on sign-up bonus alone. A bonus disappears after a few months; fees and limits last for years.
- Ignoring cash deposit limits. Cash-heavy businesses can pay large monthly fees at banks built for online businesses.
- Giving everyone full access. Use separate logins and permissions for staff and your bookkeeper.
- Never reconciling. Unreconciled accounts hide errors, fraud and bank fees.
Key terms
- Commingling: mixing personal and business money in the same account.
- ACH: the Automated Clearing House network used for direct deposits, payroll and electronic bill payments.
- Positive Pay: a fraud service that matches checks presented for payment against the list of checks you issued.
- Ownership category: the way an account is titled, which determines how deposit insurance applies.
- Sweep account: a service that automatically moves cash between accounts or banks.
The bottom line: open a business checking account the week you form the business, add a business savings account for your reserve and taxes, and choose a bank that can grow with you into credit. A relationship with a local banker is worth more than a few dollars in fees when you need your first loan.

Frequently asked questions
Do I need a business bank account for an LLC?
California does not require one by law, but you should treat it as required. Keeping LLC money separate supports your liability protection, your tax records and your ability to borrow.
Can a sole proprietor open a business bank account?
Yes. Banks usually ask for your ID, your Social Security number or EIN, and a filed fictitious business name statement if you use a trade name.
Is money in a business bank account insured?
Yes, at FDIC-insured banks and NCUA-insured credit unions, up to $250,000 per depositor, per institution, per ownership category. Business accounts are insured separately from your personal accounts.
Should I choose a big bank or a credit union?
Choose based on how you operate. Large banks offer more branches and services; community banks and credit unions often charge lower fees and make more local lending decisions.
What is the best way to pay myself from a business account?
Transfer money to your personal account as an owner draw or salary, depending on your business structure, instead of paying personal bills directly from the business account.
