"Questions have arisen concerning what information must be provided in an employee consent and whether an employee consent may be requested, furnished, and retained in an electronic format. The proposed revenue procedure clarifies that, in addition to providing the relevant name, address, and taxpayer identification number, a valid employee consent must identify the basis of the claim for refund and be signed by the employee under penalties of perjury. The proposed revenue procedure also provides guidance as to what constitutes 'reasonable efforts' to secure an employee consent when a consent is not obtained. The proposed revenue procedure permits, but does not require, the employee consent to be requested, furnished, and retained in an electronic format, as an alternative to a paper format."
