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.
