Identification
Full legal name, tax identification number, and current address for the principal and the authorized agent.
A clear written authorization reduces ambiguity about who may access tax records or act in tax matters, helps prevent identity and reporting errors, and documents consent needed for third-party interactions with payers and the IRS. It protects the principal by specifying limits, duration, and revocation procedures while providing payers and agents with a record of authority.
