How to Open a Business Bank Account

Opening a business bank account is one of the most important early steps for any new business. Mixing personal and business money makes bookkeeping messy, hurts your professional credibility, and can weaken the legal protection of an LLC or corporation. The good news: opening a business account is straightforward if you have the right paperwork ready.

This is plain-English starter content. For broader context, see our Learn hub, the business basics overview, and our bookkeeping basics guide.

Why a separate account matters

Three reasons every business should have its own bank account:

1. Liability protection. If your business is an LLC or corporation, mixing personal and business money is the easiest way to "pierce the corporate veil" — meaning a court could decide your personal assets are also at risk in a business lawsuit.
2. Cleaner bookkeeping. Every business transaction in one place makes monthly reconciliation, tax filing, and any future audit dramatically easier. See our bookkeeping basics guide.
3. Professionalism. Customers writing checks to "ABC Plumbing LLC" instead of "John Smith" looks more credible — and some payment platforms require a business account.

The SBA's open a business bank account page covers the basics.

When to open one

Open the business account immediately after:

1. Your state has approved your LLC or corporation formation
2. You have your IRS EIN confirmation letter

Sole proprietors with no employees can technically use a personal account, but most banks will let you open a business account in the sole proprietor's name with just an SSN — and doing so is still a much better idea than mixing.

What you need to bring

The exact list varies by bank, but expect to provide most of:

• Government-issued photo ID for each owner who will be on the account
• EIN confirmation letter from the IRS (the CP 575)
• Formation documents filed with your state — Articles of Organization for an LLC, Certificate of Incorporation for a corporation, partnership agreement for a partnership
• Operating agreement (LLC) or bylaws (corporation) — some banks require these, some don't, and they may also ask who is authorized to sign on the account
• Business address proof (utility bill, lease)
• DBA / fictitious name filing if your business operates under a different name
• Beneficial ownership information — federal rules require banks to identify any owner with 25% or more ownership, plus one person with significant control

Sole proprietors often need only ID, EIN (or SSN), and any DBA filing.

This is general info, not legal or financial advice — talk to your bank for their specific requirements.

Beneficial ownership and FinCEN

Federal anti-money-laundering rules require banks to collect ownership information when opening business accounts. Separately, federal law requires most U.S. business entities to report beneficial owners to FinCEN (Financial Crimes Enforcement Network). The USA.gov small business hub and the SBA both link to the current rules. Filing rules and deadlines change — check the latest before relying on any specific date.

How to choose a bank

Compare at least three options before opening. Things to evaluate:

• Monthly maintenance fee. Some accounts are free if you keep a minimum balance; others charge $10 to $30 per month no matter what.
• Minimum balance to waive fees. Common thresholds range from $500 to $5,000.
• Per-transaction fees. Most accounts include 100 to 500 free transactions per month, then charge a small fee per additional one. High-volume businesses should pay attention here.
• Cash deposit limits. Common limits are $5,000 to $10,000 per month free, with fees above that. Cash-heavy businesses (restaurants, retail) need higher limits.
• Online and mobile banking quality. Mobile check deposit, ACH, bill pay, and integrations with accounting software are the table stakes today.
• Branch network. If you take cash deposits or need wire transfers, in-person banking still matters.
• Treasury services for growing businesses. Wires, lockbox, positive pay, and merchant services if you need them later.

The largest national banks, regional banks, online-only business banks (Bluevine, Mercury, Relay, Lili, Novo, Found, etc.), and credit unions all offer business accounts. Online-only banks often have lower fees but no in-person service. Credit unions often have low fees and personal service but smaller branch networks. There is no single right answer — pick what fits how your business actually moves money.

Federal deposit insurance

Money in U.S. business checking accounts is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per depositor, per insured bank, per ownership category. Credit union deposits are insured by the NCUA (National Credit Union Administration) on similar terms. Above $250,000 you may want to spread balances across multiple banks or use a sweep service.

Setting up the account

Once approved, complete these basic setup steps in the first week:

1. Order checks if your business will pay any vendors or contractors by check
2. Order a debit card in the business name
3. Set up online banking and mobile app login
4. Connect to your accounting software (QuickBooks, Xero, Wave, etc.) for automatic bank feed
5. Set up ACH and wire capability if you need to send payments electronically — see our accepting payments guide
6. Sign up for a separate business credit card (most banks offer one to existing business customers)

Common mistakes

• Using the wrong legal name. The bank account name must exactly match your IRS EIN registration. Even small differences cause headaches.
• Skipping the operating agreement. Some banks ask, and even when they don't, having one helps if there's ever a dispute about who can sign.
• Mixing money "just this once." It rarely stays that way. Set the rule on day one: business account for business, personal account for personal.
• Not setting up a separate tax savings account. Move estimated tax money to a separate savings account immediately so you don't accidentally spend the IRS's share.
• Ignoring the monthly fee. A $20 monthly fee is $240 per year. Over five years that pays for a lot of accounting software.

Sole proprietors and DBAs

A sole proprietor with no DBA can usually open a business account in their personal legal name plus business activity. With a DBA, most banks will let the account read "John Smith DBA Sunrise Bakery" so customers can write checks to either name. Bring the filed DBA paperwork with you.

Switching banks later

Opening the right account at the start matters because switching is annoying. You have to update direct deposit, recurring vendor payments, processor payouts, customer auto-bill, and your accounting software bank feeds. Take the time to compare options upfront so you do not have to redo this in a year.
