It's a common situation for new businesses: banking gets set up around whatever's convenient at first, a personal checking account, a card someone already had, and stays that way until tax season, when an accountant has to untangle which of hundreds of transactions were the business and which weren't.
That version of the mistake just costs a headache. Depending on your entity type and your state, it can also complicate the liability protection an LLC or corporation is designed to give you.
Why does a business bank account matter beyond "keeping money separate"?
A business bank account does two jobs. It keeps business money separate from personal money, which helps support the liability separation an LLC or corporation is designed to provide (along with other formalities, depending on your state and entity type). And it's the account everything else eventually connects to: a merchant account, a line of credit, a vendor's ACH payment. Picking the wrong one doesn't usually break anything immediately. It shows up later, as a fee you didn't expect or a feature you needed and didn't have.
What should I actually compare between business bank accounts?
Monthly fees and minimum balance. Most business checking accounts charge a monthly fee unless you maintain a minimum balance or meet a transaction threshold. Read the fine print on what counts toward that minimum: some banks only count deposits, not your running balance.
ACH and wire support, not just a debit card. If you'll ever pay a vendor, receive a payment from a client, or run payroll, you need ACH transfers at minimum. Some accounts marketed for freelancers and side businesses don't include this by default.
Cash deposit limits and fees. If your business handles cash, check the monthly free cash deposit limit. Many business accounts cap it and charge per-$100 after that, which adds up fast for a cash-heavy business.
Whether it can grow with you. A checking account with a different name on it isn't a banking relationship. Ask what happens when you need a business credit card, a line of credit, or a loan later. Is that a conversation with a real person at the same bank, or a cold application somewhere else?
How it connects to getting paid. Opening the account is step one. At some point you'll need a way to actually accept payment from customers: a card reader, an online checkout, invoicing. Worth asking upfront whether the account you're opening makes that easier or harder down the line, even if it's not something you need on day one.
What do I need to open a business bank account?
Requirements vary by bank, but you'll typically need:
- Your EIN confirmation letter (the CP 575 from the IRS)
- Formation documents (Articles of Organization/Incorporation, or a DBA filing if you're a sole proprietor)
- A government-issued ID for each owner with 25%+ ownership
- Sometimes an operating agreement or bylaws, depending on the bank
What red flags should I watch for when opening a business bank account?
- "Free" accounts that convert to a monthly fee after an introductory period, without a clear notice
- No live customer support line, only chat or email, for anything beyond routine questions
- Minimum balance requirements that don't match your actual cash flow in the first 6 months
FAQ
Do I need a separate business bank account if I'm a sole proprietor?
Legally, not always, but practically, yes. Without one, you lose the clean paper trail that protects you at tax time and makes the business look legitimate to banks, vendors, and landlords.
Can I open a business bank account before I have an EIN?
Most banks require the EIN confirmation letter as part of account opening. Get the EIN first; it's typically the first document requested.
Is an online-only bank a safe choice for a new business account?
Many online business banks are FDIC-insured through a partner bank and work fine for day-to-day operations. The trade-off is usually no in-person branch and, sometimes, slower human support when something goes wrong.
