Core LLC documents
Banks commonly request the LLC’s articles of organization or certificate of formation, EIN or other tax identification number, business address and information about the company’s owners and managers. Some institutions also request the operating agreement, especially when signing authority is not obvious from the formation record.
Beneficial ownership and control information
Banks apply federal customer due diligence requirements when opening accounts for many legal entities. Be prepared to provide identifying information for beneficial owners and a control person as required by the bank’s procedures. FinCEN’s 2026 relief reduced repetitive verification for existing legal-entity customers in certain circumstances, but it did not eliminate risk-based due diligence.
Define signer authority before opening
For a single-member LLC, authority may be simple. Multi-member LLCs should decide who can sign, initiate ACH or wires, add users, order cards and close accounts. The operating agreement or a banking resolution can help document that authority.
Separate operating cash from reserves
As the business grows, it may be useful to use one checking account for operations and another insured deposit account for reserves or tax cash. The account titles and ownership should reflect the LLC so the business records remain clear.
Compare features that matter to the LLC
The right account depends on transaction volume, cash deposits, payment methods, user access, branch needs and future lending or treasury requirements. A very small LLC may value simplicity and $0 monthly maintenance; a larger one may benefit from a relationship account with more included activity and controls.
Primary sources and reference material
Model the account around the way your business actually moves money.
Fees, balances, transactions, cash deposits, payment tools and controls should be evaluated together. A lower headline fee is not automatically the lower-cost operating account.
