Form 8879‑C, IRS E‑File Signature Authorization for Corporations, is the official document that authorizes the IRS to accept an electronically filed corporate income‑tax return (Form 1120, 1120‑S, 1120‑F, etc.). Instead of mailing a paper signature, corporations can sign electronically using this fillable PDF, saving time and reducing errors.
The form serves as a written declaration that the corporate officer signing the return has reviewed the return, the information is accurate, and the corporation authorizes the IRS to process the e‑filed return. It must be signed by an authorized officer (president, treasurer, or other corporate officer) and attached to the electronic filing.
