A company bank account is separate from your personal account and holds money in your business's name
A company bank account is a deposit account registered to your business entity—not to you personally. The bank treats deposits and withdrawals as belonging to the company itself. This separation matters legally: it protects your personal assets if the business is sued, it makes tax reporting clearer, and it signals to the IRS that you are running an actual business rather than a side hustle.
You will need to provide the bank with your business formation documents (articles of incorporation, articles of organization, or a DBA certificate), your Employer Identification Number (EIN), and personal identification for whoever signs the account paperwork. Some banks require a minimum deposit to open; others do not. The account can accept checks, ACH transfers, wire transfers, and card payments just like a personal account, but the money legally belongs to the business.
The main reason to open one is liability protection. If you operate as a sole proprietor or partnership without a separate account, creditors or plaintiffs can reach your personal bank account. If you operate as an LLC or corporation and keep business money in your personal account, a court may "pierce the corporate veil" and hold you personally liable anyway. A dedicated business account is the clearest evidence that you are maintaining the separation the law requires.
Key Takeaways
- A company bank account is registered to your business entity, not to you personally, and provides legal protection if your business is sued or owes money.
- You will need your business formation documents, EIN, and personal ID to open an account; some banks require a minimum opening deposit.
- Money in a company account belongs to the business, not to you, even if you own the business—mixing personal and business funds can weaken liability protection.
- The account accepts the same payment methods as a personal account but generates separate records for tax reporting and business accounting.
- Overdraft fees, monthly maintenance fees, and transaction limits vary by bank and account type, so compare terms before opening.
What documents you need to open the account
The bank will ask for proof that your business exists and that you have the authority to open an account on its behalf. If you are a sole proprietor, you may only need your personal ID and an EIN (or your Social Security number if you have not obtained an EIN yet). If you are an LLC or corporation, you will need the articles of organization or incorporation filed with your state, proof of your EIN, and a resolution or certificate authorizing you to open the account.
Bring a government-issued ID—a driver's license or passport. Some banks also ask for a second form of ID or a recent utility bill to verify your address. If you are opening the account on behalf of someone else (as a bookkeeper or accountant, for example), bring a power of attorney document or a board resolution granting you that authority. The bank will keep copies of everything you submit.
If your business is brand new and you have not yet received your EIN from the IRS, you can apply for one online at irs.gov and receive it immediately. You do not have to wait for a letter in the mail. Some banks will open an account using your Social Security number temporarily and switch to the EIN once you receive it.
How liability protection actually works
Liability protection depends on two things: your business structure and how you operate the account. If you are a sole proprietor, a company bank account does not shield you from personal liability—you are personally responsible for business debts no matter where the money sits. If you are an LLC or corporation, the company account is one of several steps required to maintain the legal separation between you and the business.
Courts look at whether you have treated the business as a separate entity. That means using the company account for business transactions, not mixing personal and business money, keeping business records separate from personal records, and not taking money out of the account as if it were your personal savings. If you deposit business revenue into your personal account and pay business bills from it, a court may decide the separation is not real and hold you personally liable anyway.
The account itself does not create protection—the business structure does. The account is the evidence that you are maintaining that structure. If you operate as an LLC but run all money through your personal account, you have lost most of the benefit of forming an LLC in the first place.
Monthly fees, overdrafts, and transaction limits
Most banks charge a monthly maintenance fee for a business account, ranging from zero to $25 or more depending on the bank and account type. Some waive the fee if you maintain a minimum balance (often $1,000 to $5,000) or set up direct deposit. Others charge per transaction—for example, $0.25 to $1.00 per check deposited or per ACH transfer sent. A few online banks offer business accounts with no monthly fee and no per-transaction charges.
Overdraft fees occur when you spend more than the account balance. Most banks charge $25 to $35 per overdraft, and some charge multiple times per day if several transactions post at once. Some accounts include overdraft protection, which links your business account to a savings account or credit line and automatically transfers money to cover the shortfall—usually for a smaller fee or no fee at all.
Transaction limits vary widely. Some accounts allow unlimited checks and transfers; others cap the number of ACH transfers or wire transfers per month. If you process many payments, ask the bank about limits before opening. Online banks often have higher limits than brick-and-mortar banks, and business accounts usually have higher limits than personal accounts.
How deposits and withdrawals are recorded
Every deposit and withdrawal creates a record that the bank reports to you monthly on a statement. That statement shows the date, amount, description (if provided), and running balance. The bank also reports certain transactions to the IRS: if you receive more than $20,000 in a single transaction or $20,000 total in a calendar year from a single customer via cash, the bank files a Currency Transaction Report (CTR). If the pattern looks suspicious, the bank may file a Suspicious Activity Report (SAR) instead.
You do not have to do anything when these reports are filed—they are routine. But they mean the IRS has a record of large cash deposits to your business account. This is why accurate bookkeeping matters: if your tax return does not match the deposits the bank reported, the IRS will notice.
Withdrawals via check, debit card, or ACH transfer all leave a paper trail. Even cash withdrawals are recorded on your statement. This record is your proof of how money moved in and out of the business, which you will need for tax reporting and for accounting purposes if you ever sell the business or apply for a loan.
Reconciling the account each month
Reconciliation means comparing your records to the bank's statement and making sure they match. You record every transaction in your accounting software or ledger as it happens; the bank records the same transactions as they clear. Sometimes there is a timing difference—you write a check on Monday, but the bank does not clear it until Friday. At the end of the month, you compare your balance to the bank's balance and account for those timing differences.
Start with the bank's ending balance from the statement. Add any deposits you made that have not cleared yet. Subtract any checks you wrote that have not cleared yet. The result should match your accounting records. If it does not, look for a transaction that is missing or recorded twice, or a deposit or check amount that does not match.
Reconciling monthly takes 15 to 30 minutes if you have kept good records. It catches errors early—a bank mistake, a duplicate charge, a fraudulent transaction—before they compound. Most accounting software (QuickBooks, FreshBooks, Wave) can match transactions automatically and flag ones that do not match.
When you need more than one account
Some businesses open a second account to separate different types of money. A nonprofit might have a general operating account and a restricted-funds account for donations earmarked for a specific purpose. A contractor might have an account for client payments and a separate account for payroll and taxes. A business with multiple locations might have a main account and branch accounts.
The reason is usually accounting clarity, not legal requirement. Separating money by type makes it easier to track spending, forecast cash flow, and prepare tax returns. It also makes it harder to accidentally spend money that is supposed to be reserved for taxes or payroll. If you are just starting out, one account is enough. As the business grows, you can add accounts if the complexity warrants it.
Each additional account costs money—usually another monthly fee—so weigh the benefit against the cost. Some banks waive fees on secondary accounts if you maintain a certain total balance across all accounts.
Frequently Asked Questions
Can I use a personal bank account for my business?
Legally, yes, but it weakens your liability protection. If you operate as an LLC or corporation, mixing personal and business money in one account can give a court reason to hold you personally liable for business debts. The IRS also prefers to see a separate business account—it makes tax audits easier to defend. Most banks prohibit using a personal account for regular business deposits anyway.
What if I am a sole proprietor—do I still need a business account?
A sole proprietor does not get liability protection from a business account because the business and the owner are legally the same entity. However, a separate account still makes bookkeeping and tax reporting much simpler. The IRS can see exactly which deposits are business income and which are personal. Most accountants recommend it even for sole proprietors.
What happens if I overdraft the account?
The bank will charge an overdraft fee (usually $25 to $35) and may decline the transaction. If you have overdraft protection linked to another account, the bank will transfer money automatically to cover it, usually for a smaller fee. If you overdraft repeatedly, the bank may close the account. Set up alerts so you know your balance before making large payments.
Do I need an EIN to open a business account?
Most banks require an EIN if you operate as an LLC or corporation. Sole proprietors can use their Social Security number instead, though some banks prefer an EIN. You can obtain an EIN free from the IRS at irs.gov in minutes; you do not have to wait for a letter. If you do not have one yet, ask the bank whether they will open the account with your Social Security number temporarily.
Can someone else access the account if I add them as a signer?
Yes. When you add an authorized signer to the account, that person can deposit checks, withdraw money, and make transfers just as you can. The bank will ask for their ID and may require them to sign a card. You remain liable for anything they do with the account, so only add people you trust completely. You can remove a signer at any time by notifying the bank in writing.
