Can a single-member LLC open a business bank account with only an SSN, or are extra documents needed?
While some regional banks technically allow single-member LLCs to open accounts using an owner’s Social Security Number, most commercial institutions mandate an Employer Identification Number (EIN) for proper account setup. Relying solely on an SSN risks mingling personal and entity liability, which weakens your corporate veil protection. Along with your federal tax identification, the bank will ask for stamped Articles of Organization, a basic single-member Operating Agreement, and your state business license. Bringing proof of address—such as an official lease or commercial utility statement—is also standard practice.
