Business Bank Account Requirements
Table of Contents
So you're opening a business bank account. Here's the short version: bring proof the business exists, proof you exist, a physical address, and a tax ID. That's the core. Almost every US bank wants those four things, give or take. The specifics wobble depending on your bank, your business structure, and whether you're walking into a branch or clicking through an app on your couch. Newly formed businesses usually qualify fine — but if you're a sole proprietor or a single-member LLC, expect a little more side-eye. Not personal. Regulators just want the bank to know who actually controls the account.
Key takeaways
- Minimum? Formation docs, a tax ID, your personal ID, and something proving your address.
- Why the paperwork? Federal rules — the whole Know Your Customer and Customer Due Diligence apparatus — force banks to identify owners and understand what your business actually does.
- Sole proprietors and single-member LLCs can almost always get an account. The paperwork just looks different than a corporation's.
- The name on the account needs to match your legal business name and your tax records. Exactly. Not close enough.
- Here's the thing that trips people up: tiny mismatches. A different address. A missing operating agreement. Those are the delays, not big dramatic rejections.
What documents do you need to open a business bank account?
Below is what most US banks ask for. Your bank might want less. It might want more. Don't guess — pull up their checklist before you show up or start that online application.
| Requirement | What it usually means | Who needs it |
|---|---|---|
| Formation documents | Articles of incorporation or organization, a state filing receipt, or a certificate of good standing | Corporations, LLCs and other registered entities |
| Business tax ID | An Employer Identification Number (EIN) from the IRS, or your Social Security number for some sole proprietors | All applicants |
| Personal identification | Government-issued photo ID, such as a driver's license or passport | Every owner, signer and often every controlling person |
| Ownership information | An operating agreement, bylaws or a list of members and their ownership percentages | LLCs and corporations with multiple owners |
| Business address | A physical street address plus a mailing address; some banks accept a registered agent address | All applicants |
| Business license or permit | A local or state license required for your industry, if one applies | Businesses in regulated sectors |
| Initial deposit | Funds to open the account, which varies by bank and account type | All applicants |
| Business details | A short description of what the business does, expected transaction volume and where customers are located | All applicants |
One more layer: banks run applicants through databases that track business history and identity. Had an account closed before for suspected fraud? Vague about what your business does? Congratulations, your application just got slower. And if you're in a cash-heavy line of work — restaurants, retail, salons — prepare yourself. They will ask how you handle cash.
Business bank account requirements by business structure
Sole proprietors
No employees? You can often skip the EIN and use your Social Security number. And you may not even have a state business license to point to. Doesn't matter — the bank still wants ID and proof of address. Trading under a name that isn't your own? Many banks will ask to see your fictitious business name filing.
Single-member LLCs
Formation certificate plus EIN. That's the standard. Here's an odd wrinkle, though: some banks ask for an operating agreement even when most states don't legally require a single-member LLC to have one. Keep a copy ready anyway. Costs you nothing.
Multi-member LLCs and corporations
Now the bank wants to know everyone. Anyone with a meaningful stake — often defined as 25% or more — plus anyone who controls the business. Each of those people submits ID and personal details. Which explains why a startup with four founders takes noticeably longer to open an account than a solo operation. More people, more paperwork, more waiting.
A short scenario
Picture two freelancers. They form a two-member LLC and apply online for a business checking account. Then the application just... stalls. Why? The operating agreement lists one founder's apartment as the address. The state filing lists a registered agent's office. Two different addresses. The bank sees the mismatch and asks for a utility bill to confirm the operating address. Our freelancers fix it by sending a document showing the registered agent address is the official mailing address for state filings, plus a lease for the workspace they actually use. Account opens a week later. Lesson learned the hard way: get your address, business name, and ownership records lined up across every single document before you hit apply.
Requirements for online-only and non-resident applications
Digital banks usually want the same core documents — they just swap the branch visit for a selfie or a quick video call. Fair trade. But watch out: some online banks flat-out refuse certain industries, cash deposits, or businesses with no US presence at all. And if you're a non-US resident trying to open a US account? Expect more hoops. A US address, a US phone number, and identification that's been notarized or apostilled are common asks. Rules vary wildly by jurisdiction — never assume one bank's policy applies everywhere. Same story in the EU, by the way, where anti-money-laundering directives drive similar checks, and businesses may need a local company registration extract alongside their ownership records.
Common mistakes and risks
- Applying before formation is complete. The state needs to approve your filing and it has to show up in public records. Most banks won't budge until it does.
- Name mismatches. Account name, tax records, formation docs — if they don't match exactly, expect a delay. Every time.
- Skipping the operating agreement. Legally required or not, banks ask for it constantly. Not having one ready can cost you days.
- Using a virtual mailbox as the only address. Some banks take commercial mail addresses. Others won't touch them. Ask first, apply second.
- Misdescribing business activity. Say something vague about what your business does and watch the compliance review light up like a Christmas tree.
- Ignoring the due diligence questionnaire. If the bank asks about expected deposits and transaction volume, they want a real number. A guess isn't an answer.
How to prepare
- Confirm your business is registered, and grab a certificate of good standing if your bank wants one.
- No EIN yet? Apply. Sole proprietors with no employees can decide for themselves whether they need one.
- Collect ID from every owner and signer — and actually check that the names match across every document. You'd be surprised how often they don't.
- Write a one-paragraph description of your business. Estimate monthly deposits and transaction counts while you're at it.
- Print or save digital copies of formation documents, the operating agreement, and any licenses.
- Set aside the minimum opening deposit. And ask about monthly fees and balance requirements — those sneaky little costs add up.
FAQ
Can I open a business bank account without an EIN?
Often, yes. Sole proprietors without employees can frequently use their Social Security number instead. But LLCs, corporations, and partnerships? They generally need an EIN, and most banks will insist on it.
Do I need a business license to open an account?
Not always. Banks ask for a license when your industry or local jurisdiction requires one. Food service, childcare, financial services — regulated sectors like those? Expect to show it.
Can I open an account before my business earns revenue?
Usually, yes. Plenty of banks open accounts for pre-revenue businesses. Some want a minimum deposit first. Either way, your business description and formation documents still need to be in order.
What if I run the business from home?
Many banks are fine with a home address. Some want proof — a utility bill, a lease. Check whether yours accepts residential addresses before you apply, not after.
How long does opening an account take?
In person? Could be same day. Online? Usually a few business days. And multi-owner businesses can drag on longer if extra verification kicks in.
What happens if I change business structure later?
You'll probably need to update the account records, and some banks will make you close the account and reopen a new one. Contact your bank promptly after a structural change — dragging your feet invites compliance flags.
