You’d be surprised how many new business owners walk into a bank ready to open an account — and walk out empty-handed.

We were talking recently with a friend who manages the business-banking department at a local credit union. She said nearly half of the people who show up to open business accounts have no documentation at all. No registration. No paperwork. Just a great idea — and a debit card.

If that sounds familiar, don’t worry. Most entrepreneurs don’t realize how much documentation is required or why it’s so important. So let’s break down exactly what you need — and why skipping these steps can cost you big later.

Why a Separate Business Bank Account Matters

If you’ve formed an LLC or corporation, one of the main benefits is personal asset protection — your house, car, and savings can’t be touched if the business is sued.

But that protection disappears the moment you start mixing personal and business money.

When you commingle funds, lawyers can argue that your business isn’t a true separate entity. That’s called piercing the corporate veil, and it means they can go after your personal assets.

👉 Bottom line: Opening a dedicated business bank account isn’t just good organization. It’s legal protection.

What You’ll Need to Open a Business Bank Account

Here’s the documentation your bank will expect to see. (Requirements can vary slightly by state or bank, but this list covers the essentials.)

1. Certificate of Organization

This is the official document from your state proving your business exists.

• You’ll get it when you register your LLC or corporation.

• Print several copies and back them up digitally in Google Drive, Dropbox, or an external hard drive.

2. Federal & State Tax Documents

You’ll need:

• Your EIN (Employer Identification Number) from the IRS.

• Your state tax ID if you’re required to collect or remit state sales tax.

Note: Once you register for state tax, you must file reports even if you don’t make sales — so be sure you’re ready for that commitment.

3. Operating Agreement

Think of this as the rulebook for your company. It explains:

• Who owns the business

• How profits are divided

• How decisions are made

• What happens if an owner leaves or becomes incapacitated

Even if you’re a single-member LLC, having an operating agreement helps prove your business is separate from you personally.

✳️ Tip: You can use ChatGPT to draft a rough version, but always have an attorney review it before signing. Errors here can cause big problems later.

4. Initial Member Meeting & Resolutions

These are simple memos documenting official decisions — like authorizing the business to open a bank account or electing officers.

They aren’t always required, but having them makes your business look more legitimate and can speed up your account approval.

5. Ownership or Interest Ledger

A straightforward record of who owns what percentage of the company.
Even if you’re the only owner, note your 100% ownership.

6. Banking Information Sheet (After Opening)

Once your account is approved, ask the bank for a direct-deposit slip or a printed sheet showing:

• Account number

• Routing number

• Voided-check image

Keep that with your records — you’ll need it for payroll, payments, and vendor setup.

Make It Easy on Yourself: Create a Business Binder

To simplify everything, we’ve created a printable business-organization binder you can download.
It includes:

• A table of contents

• Tabs for each key document

• Space for notes and resolutions

When you walk into the bank, you can hand them the binder and say,

“Here’s everything you need to open my business account.”

They’ll love you for it — and you won’t have to make multiple trips printing and signing forms.

Once your binder is complete, store it in a fire-safe box or secure cabinet. It’s not just for the bank — it’s your go-to reference for every major business need.

Final Thoughts

Opening a business bank account might feel like just another piece of red tape, but it’s one of the most important steps you’ll ever take.

It protects your assets, proves your legitimacy, and sets you up for long-term success.
