A company bank account separates your business money from your personal money, which protects both your finances and your liability
A business bank account is a separate account held in your company's name rather than your personal name. The bank treats the account as belonging to the business entity itself—whether that's an LLC, corporation, sole proprietorship, or partnership. This separation matters legally and practically: it makes tax time simpler, it protects you if the business faces a lawsuit, and it makes it harder for creditors to come after your personal assets.
You will need to prove the business exists before opening the account. Most banks require an Employer Identification Number (EIN) from the IRS, a copy of your business formation documents (articles of incorporation or organization), and a government-issued ID. Some banks also want to see a business license or a recent utility bill showing your business address. The exact list varies by bank and by the type of business structure you have.
The account itself works like a personal checking account—you deposit money, write checks, use a debit card, and set up automatic payments. The main differences are that the bank may charge higher monthly fees, require a higher minimum balance, and offer features like merchant processing or payroll integration that personal accounts do not have.
Key Takeaways
- A business bank account is held in your company's name and legally separates your business finances from your personal finances, which protects your personal assets if the business is sued.
- You will need an EIN from the IRS, your business formation documents, and a government ID to open an account; some banks also require a business license or proof of address.
- Business accounts typically charge monthly fees ranging from $10 to $50 depending on the bank and account type, and many require a minimum balance.
- The account makes tax filing and bookkeeping simpler because all business income and expenses flow through one place, separate from your personal spending.
- You can add authorized users or signers to the account, but the business itself remains the legal owner and is responsible for all activity.
What documents you need to bring to the bank
Banks have different requirements, but most ask for the same core set of documents. You will need a government-issued photo ID (driver's license or passport), your Employer Identification Number (EIN), and proof that your business exists. Proof of existence usually means articles of incorporation (for a corporation), articles of organization (for an LLC), or a partnership agreement. If you are a sole proprietor without a formal business structure, some banks will open an account with just your personal ID and EIN, though others may ask for a business license or a DBA (doing business as) certificate filed with your state.
Bring a document showing your business address if it is different from your home address. This can be a lease, a utility bill, or a mail receipt. If you are opening the account online, the bank will ask you to upload these documents instead of bringing them in person. Have clear, legible copies ready—blurry photos or partial documents slow down the process.
If you are not the sole owner, bring documentation showing who the owners are and their ownership percentages. For corporations, this is the corporate resolution or board minutes authorizing the account. For LLCs, it is the operating agreement. The bank needs to know who has authority to sign checks and make decisions about the account.
Monthly fees and minimum balance requirements
Business checking accounts are not free. Monthly maintenance fees typically range from $10 to $50 depending on the bank, the account type, and how much money you keep in the account. Some banks waive the fee if you maintain a minimum balance—often $1,000 to $5,000—or if you set up direct deposit of business income. Others charge the fee regardless and offer no way to avoid it.
Beyond the monthly fee, watch for per-transaction charges. Some banks charge $0.25 to $1.00 for each check you write, each ACH transfer you make, or each wire transfer you send. If you process a lot of transactions, these add up quickly. A few banks offer unlimited transactions for a flat monthly fee; others charge by the transaction. Compare the fee structure to your actual business needs before opening the account.
Overdraft fees are another cost to understand. If your account balance drops below zero, the bank will charge an overdraft fee—usually $25 to $35 per occurrence. Some banks offer overdraft protection, which links your business account to a savings account or line of credit and automatically transfers money to cover the shortfall, but this service may have its own fee.
How a business account protects your personal liability
The legal protection comes from the separation itself. If your business is structured as an LLC or corporation, the business is a separate legal entity from you personally. When you keep business money in a business account and personal money in a personal account, you are respecting that separation. If someone sues the business or the business owes money it cannot pay, creditors can go after the business assets—the money in the business account—but not your personal assets like your house or car.
This protection is called piercing the corporate veil, and it happens when a court decides the business and owner are so mixed together that they should be treated as one. Keeping separate bank accounts is one of the main ways you prevent this. If you run business money through your personal account, a court may decide you have not respected the separation and allow creditors to come after your personal assets.
The protection is not automatic and is not absolute. It depends on your business structure (sole proprietors have no liability protection regardless of their bank account), how you run the business, and what state you are in. But maintaining a separate business account is one of the clearest, cheapest steps you can take to support that protection.
Adding signers and authorized users to the account
You can give other people the power to access and use the business account without making them owners of the business. An authorized user can use a debit card and make purchases, but cannot write checks or make large transfers. A signer can write checks and authorize transfers. The exact titles and permissions vary by bank.
To add someone, you will need their full legal name, date of birth, and Social Security number. The bank will run a background check on them. You will also need to decide what permissions they have—can they write checks up to any amount, or only up to a limit you set? Can they add or remove other signers? Can they close the account? These decisions stay with you as the account owner, and you remain responsible for everything that happens in the account, even if someone else makes the transaction.
Removing a signer is straightforward: contact the bank and ask them to remove the person's authority. The person's name may stay on the account history, but they will no longer be able to access it or make transactions. If someone with signing authority leaves your business, remove them when ready.
Tax reporting and record-keeping with a business account
A business account makes tax time simpler because all your business income and expenses flow through one place. When you file your business tax return, your accountant or tax software can pull statements directly from the bank and match them to your income and expense records. If business and personal money are mixed in one account, you have to sort through personal purchases to find the business ones, which is time-consuming and error-prone.
The bank will send you a 1099-NEC or 1099-MISC form at the end of the year if you received more than $600 in payments from certain types of clients (the threshold and rules vary by payment type). You will also receive monthly statements showing all deposits and withdrawals. Keep these statements for at least three years in case the IRS asks questions about your income or deductions.
You do not need to use the bank's bookkeeping tools, but many business accounts come with them. These tools can automatically categorize transactions, track expenses by category, and generate reports. If you use accounting software like QuickBooks or FreshBooks, you can usually connect your business bank account directly so transactions import automatically.
How to choose between banks and account types
Different banks offer different features and fee structures. Large national banks like Chase, Bank of America, and Wells Fargo have many branches and ATMs, but they tend to charge higher fees and require higher minimum balances. Online banks like Mercury, Brex, and Novo have lower fees and no minimum balance, but they have no physical branches. Credit unions often have lower fees than national banks and may offer better customer service, but you have to be a member.
Consider what you actually need. If you process a lot of credit card payments, look for a bank that offers merchant processing or has partnerships with payment processors. If you need to deposit cash frequently, a bank with physical branches near you matters. If you rarely visit a branch and mostly use online banking, an online-only bank may save you money. If you need a business line of credit or a business credit card, some banks bundle these with checking accounts.
Read the fee schedule carefully before opening the account. Some banks advertise "free" checking but charge per transaction. Others charge a monthly fee but include unlimited transactions. Calculate what you will actually pay based on how many checks you write, how many transfers you make, and whether you can meet the minimum balance requirement.
Frequently Asked Questions
Do I need a business bank account if I am a sole proprietor?
You are not legally required to have one, but it is strongly recommended. A sole proprietor has no liability protection, so a separate account does not shield your personal assets the way it does for an LLC or corporation. However, it still makes bookkeeping and tax filing much simpler, and it looks more professional to clients and vendors. The cost is usually worth it.
What happens if I use my personal account for business money?
The IRS will still tax you on the income, and you can still deduct business expenses. However, sorting personal and business transactions at tax time becomes difficult and error-prone. For an LLC or corporation, mixing accounts can also weaken your liability protection if you are ever sued. Banks may also close the account if they discover you are using it for business purposes when you opened it as personal.
Can I have more than one business bank account?
Yes. Some businesses open separate accounts for different purposes—one for operating expenses, one for payroll, one for a specific project or client. Each account will have its own monthly fee, so weigh the organizational benefit against the cost. You will also need to track which account is which when you file taxes.
What if I need to change banks?
Contact your new bank and ask them to help you transfer the account. They can set up a new account and move your direct deposits and automatic payments over. You will need to notify clients and vendors of your new account number if they send you payments or if you have automatic payments set up. Close the old account once all transactions have cleared.
Can I open a business account online, or do I have to go to a branch?
Most banks now allow you to open a business account online. You will upload photos of your documents, verify your identity, and fund the account electronically. The process usually takes one to three business days. Some banks still require an in-person visit, especially if your business structure is complex or if you are opening a business credit line at the same time.
