What Documents do I Need to Open a Business Bank Account?
Financial institutions must comply with both federal regulations and internal risk policies, which is why the list of opening bank account documents required tends to be comprehensive. Failing to prepare the full set often results in delays, account denials, or even compliance investigations.
Let’s examine the core bank docs typically requested:
Personal Identification: A valid government-issued photo ID (such as a passport or driver’s license) for each business owner or authorized signatory.
Tax Identification Number: In most cases, this is your Employer Identification Number (EIN) from the IRS. Sole proprietors without employees may use a Social Security Number, but banks increasingly prefer an EIN to ensure business legitimacy.
Business Formation Documents: These include Articles of Incorporation for corporations, or Articles of Organization for LLCs. They serve as legal proof that your business is formally registered and authorized to operate.
Business License or Permit: This document confirms that your business meets all local and state requirements. Not all businesses need one, but if yours does, it will be mandatory for account setup.
Operating Agreement or Bylaws: For LLCs and corporations, these internal governance documents define ownership roles and operational rules—key information banks require to identify account authority.
Proof of Business Address: Utility bills, lease agreements, or any document officially verifying your business's physical location.
Each of these documents needed to open a business bank account serves a specific legal, tax, or fraud prevention purpose. The Bank Docs Tool helps ensure no detail is missed by compiling a customized list that matches your specific entity type and banking requirements.
Required Documentation by Business Structure Type
Each business entity comes with its own set of legal definitions, decision-making protocols, and ownership documentation. That’s why banks request tailored required documentation based on the entity structure. Let’s break it down:
Sole Proprietorship
Typically, it is the simplest to form, yet still requires documentation to prove legitimacy.
Documents required for bank account opening:
Government-issued ID of the owner.
Business license (if mandated by state/city).
DBA (Doing Business As) certificate if operating under a different name.
EIN (optional but recommended).
Example: A freelance writer using a brand name like “BrightWord Studio” will need a DBA certificate in addition to their ID.
General Partnership
Multiple individuals share ownership, increasing documentation complexity.
Documents required:
Personal IDs for each partner.
Partnership Agreement outlining authority and shared ownership.
EIN.
Local business licenses or permits.
Example: A two-person landscaping business must clarify account authority through the partnership agreement.
LLC (Limited Liability Company)
The most common structure among startups is due to flexibility and protection.
Key documents include:
Articles of Organization.
Operating Agreement detailing ownership shares and voting rights.
EIN.
Business licenses as applicable.
Why it matters: Banks use the Operating Agreement to determine who can sign checks and access funds.
Corporation (C-Corp or S-Corp)
Complex ownership and formal governance demand extensive documentation.
Required documents:
Articles of Incorporation.
Corporate Bylaws.
EIN.
Certificate of Good Standing (in some cases).
Board resolution authorizing the account and signatories.
Example: A tech startup with multiple shareholders must provide board approval indicating who can manage the bank account.
With these distinctions in mind, the Bank Docs Tool guides you through the exact documents required for bank account opening based on your legal structure, ensuring no item is overlooked.
