Section 12-39s - Cancellation of unpaid portion of erroneously or illegally assessed taxes and credit or refund of erroneously or illegally collected taxes(a) The Commissioner of Revenue Services, of his own motion, is authorized, where any tax, penalty or interest has been erroneously or illegally assessed against any person by said commissioner, to cancel the unpaid portion of such tax, penalty or interest.(b) The Commissioner of Revenue Services, of his own motion, is authorized, if the commissioner determines that any tax, penalty or interest has been paid more than once or has been erroneously or illegally collected or computed, to credit such amount against any amounts then due and payable from such person to said commissioner and to refund, upon order of the Comptroller, the balance, if any, to such person. If such person is required by law to collect such tax or reimbursement for such tax from another person and has collected such tax or reimbursement for such tax from such other person, any amount credited or refunded under this subsection shall be credited or refunded to such other person.(c) The provisions of this section shall not be construed as authorizing suit against the state by a person against whom any tax, penalty or interest has been erroneously or illegally assessed or from whom any tax, penalty or interest has been erroneously or illegally collected and shall not be construed as a waiver of sovereign immunity.(d) The record of any cancellation under subsection (a) of this section or of any credit or refund under subsection (b) of this section shall be open to public inspection in accordance with section 1-210.Conn. Gen. Stat. § 12-39s
Intent of section is to give commissioner authority to resolve tax matters in the whole field of taxation and not in one area alone; commissioner, of his own volition, without the need for taxpayer to file a request for refund, may, at any time, order refund of an erroneous or illegal tax; there appears to be nothing in language of Sec. 12-515 or this section which ties these two statutes together for the purpose of incorporating the 3-year statute of limitations of Sec. 12-515 into that of this section. 48 CS 28.
