Any taxpayer, having paid any tax as provided by this chapter, aggrieved by the action of the commissioner or his authorized agent in fixing the amount of such tax or in imposing any penalty hereunder, may apply to the commissioner, in writing, within sixty days after the notice of such action is delivered or mailed to him, for a hearing and a correction of the amount of the tax or penalty so fixed, setting forth the reasons why such hearing should be granted and the amount in which such tax should be reduced. The commissioner shall promptly consider each such application and may grant or deny the hearing requested. If the hearing is denied, the applicant shall be notified thereof forthwith; if it is granted, the commissioner shall notify the applicant of the time and place fixed for such hearing. After such hearing the commissioner may make such order in the premises as appears to him just and lawful and shall furnish a copy of such order to the applicant. The commissioner may, by notice in writing at any time within three years after the date when any return of any taxpayer has been due, order a hearing on his own initiative and require the taxpayer or any other individual whom he believes to be in possession of relevant information concerning the taxpayer to appear before him or his authorized agent with any specified books of account, papers or other documents, for examination under oath.
