How to Open a Business Bank Account (What You Need)

Learning how do I open a business bank account and what do I need is a foundational step that too many owners skip, mixing business and personal money in one account. I will be blunt: commingling funds is the number one way to destroy your LLC’s liability protection and create a tax-time nightmare. Opening a separate account takes under an hour, and many excellent options are free. There is no good reason to delay it.

How Do I Open a Business Bank Account and What Do I Need? The Document Checklist

Requirements vary slightly by bank and business structure, but gather these:

EIN (Employer Identification Number): Free from the IRS at irs.gov. Required for LLCs, corporations, and partnerships. Sole proprietors can sometimes use their SSN, but get an EIN anyway, it is free and protects your SSN.
Business formation documents: Articles of Organization (LLC), Articles of Incorporation (corporation), or partnership agreement. Sole proprietors: your DBA certificate if operating under a trade name.
Operating Agreement or bylaws: Some banks request these to verify who can act for the business.
Business license: If your city/county requires one.
Personal ID: Driver’s license or passport for all owners/signers.
Initial deposit: $0-$100 depending on the bank. Many online banks require $0.

Call ahead or check the bank’s website for their exact list. Showing up missing one document is the classic time-waster.

Best Business Bank Accounts in 2026

Best free online: Novo, Bluevine, Relay. No monthly fees, no minimum balances, free ACH transfers, and sub-accounts for tax savings buckets. Bluevine offers interest on checking. These fintech options beat traditional banks on fees for most small businesses.
Best traditional bank: Chase Business Complete. $15/month fee (waived with $2,000 balance or qualifying activity), but unmatched branch/ATM access and excellent integration with Chase credit cards. Worth it if you deal in cash or want in-person service.
Best for cash deposits: Local credit unions. Often the lowest fees plus community relationships that matter when you need a loan later. If your business handles significant cash, a local institution with nearby branches wins.
Best for freelancers: Lili. Built for solopreneurs with automatic expense categorization and tax bucket features. Simple and free.

Fees to Watch (and Avoid)

Monthly maintenance fees: $10-$15 at traditional banks, often waivable. $0 at most online options.
Transaction limits: Many “free” accounts allow only 100-200 transactions monthly, then charge per item. High-volume businesses should check this carefully.
Cash deposit limits/fees: Online banks often charge for cash deposits via third-party networks. Cash-heavy businesses need a traditional bank or credit union.
Wire transfer fees: $15-$30 domestic. If you wire often, negotiate or choose accordingly.
Minimum balance requirements: Falling below triggers fees. Know the threshold.

Setting Up for Success (Beyond the Account)

Open a second savings account for taxes. Automatically transfer 25-30% of income there. This single habit prevents the most common small business financial crisis.
Get a business debit card and use it for all business spending. Clean separation from day one.
Consider a business credit card (separate application) to build business credit and earn rewards on business spending. Pay in full monthly.
Connect to your accounting software (QuickBooks, Wave, Xero) for automatic transaction import.
Set up direct deposit for client payments where possible; faster and more professional than checks.
Order checks sparingly. Most businesses rarely need them now; 25-50 checks last years.

Common Mistakes

Using a personal account “temporarily.” Temporary becomes permanent, and then tax time is archaeology. Open the business account before the first dollar arrives.
Choosing based on your personal bank alone. Your personal bank’s business offering might be fine, or might have terrible fees. Compare.
Ignoring the cash question. Online banks are great until you need to deposit $5,000 in cash monthly. Match the bank to how money actually moves in your business.
Adding personal signers carelessly. Anyone with signing authority can drain the account. Limit access deliberately.
Forgetting beneficial ownership rules. Banks must verify owners with 25%+ stakes under federal law. Bring all owners’ IDs.

The Bottom Line

To open a business bank account you need your EIN, formation documents (or DBA for sole proprietors), business license, personal ID, and a small initial deposit. Compare free online banks (Novo, Bluevine, Relay) against traditional options based on your cash handling and transaction volume, watch for transaction limits and cash deposit fees, and from day one keep business money strictly separate, route 25-30% to a tax savings account, and connect everything to your accounting software. One hour of setup prevents years of headaches.

Common Questions, Answered

Can I open a business bank account online?

Yes, fully online with fintech banks (Novo, Bluevine, Relay, Mercury): applications take 15-30 minutes with document uploads, and accounts open within days. Traditional banks increasingly offer online business account opening too, though some still require branch visits for certain entity types. Online opening is fastest; branch visits help when your documentation situation is unusual.

Do I need an EIN to open a business bank account?

LLCs, corporations, and partnerships: yes, universally required. Sole proprietors: some banks allow SSN, but get the free EIN anyway; it protects your Social Security number, looks more professional, and is required the moment you hire anyone. There is no downside to having an EIN, and the IRS issues them free in 10 minutes online.

How many business bank accounts should I have?

Minimum two: operating checking and tax savings. The Profit First method suggests more (profit, owner’s pay, operating expenses, taxes), which works well with free sub-accounts at banks like Relay. Start with checking plus tax savings; add buckets as the business grows. The key discipline is never spending tax money, regardless of account count.

Will a business bank account help build business credit?

Indirectly. The account itself does not report to credit bureaus, but it establishes the business’s financial identity that lenders evaluate, keeps records clean for underwriting, and is required for business credit cards and loans that do build credit. Think of it as the foundation: necessary for everything that follows, valuable in itself for organization and liability protection. The FDIC’s banking resources explain how business accounts are insured.
