May an authorized representative sign Form 1023? No. Form 1023 instructions state that an individual authorized by Form 2848 may not sign the application unless that person is also an officer, director, trustee, or other individual who is authorized to sign the application. Form 1023 is an application for the issuance of a determination letter or ruling letter by the IRS that recognizes an organization's exemption from federal income tax. Revenue Procedure 2020-5 (updated annually), requires that a letter ruling or determination letter request be accompanied by a penalties of perjury statement signed by the taxpayer, not the taxpayer's representative. This requirement is based on the concept that by signing the application, an official of the organization is assuming responsibility for the accuracy of the information. Generally, an authorized representative would not be in a position to verify the accuracy of the information provided by the organization.
