Connecticut General Statutes Title 12. Taxation § 12-3d. Deadline for penalty waiver request

To the extent that the Commissioner of Revenue Services is authorized to waive all or part of a penalty provided under this title, the commissioner shall not consider any waiver request received more than one year from the date a notice of such penalty was first sent to the person on whom the penalty was imposed. For any penalty that is reported by a taxpayer on a return filed by such taxpayer in accordance with this title, the filing date of such return shall be considered the date on which the person was notified of such penalty. Nothing in this section shall extend the date by which a protest or appeal must be filed in connection with a determination made by the commissioner.
