(b) The commissioner may require all taxpayers to keep such records as he may prescribe, and he may require the production of books, papers, documents and other data, to provide or secure information pertinent to the determination of the tax imposed by this chapter and the enforcement and collection thereof. (c) The commissioner or any person authorized by him may examine the books, papers, records and equipment of any person liable under the provisions of this chapter, and may investigate the activities of the person in order to verify the accuracy of any return made, or, if no return is made by the person, to ascertain and determine the amount required to be paid. (d) The commissioner and any representative of the commissioner authorized to conduct any inquiry, investigation or hearing hereunder may administer oaths and take testimony under oath relative to the matter of inquiry or investigation. At any hearing ordered by the commissioner, the commissioner or his representative authorized to conduct such hearing and to issue such process may subpoena witnesses and require the production of books, papers and documents pertinent to such inquiry. No witness under subpoena authorized to be issued by the provisions of this chapter shall be excused from testifying or from producing books or other documentary evidence on the grounds that the production of such books or other documentary evidence would tend to incriminate him, but such evidence or the books or documentary evidence so produced shall not be used in any criminal proceeding against him. If any person disobeys such process or, having appeared in obedience thereto, refuses to answer any pertinent question put to him by the commissioner or his authorized representative, or to produce any books and other documentary evidence pursuant thereto, the commissioner or such representative may apply to the superior court for the judicial district wherein the taxpayer resides or to any judge of said court if the same is not in session, setting forth such disobedience to process or refusal to answer, and said court or such judge shall cite such person to appear before said court or such judge to answer such question or to produce such books and other documentary evidence and, upon his refusal so to do, shall commit such person to a community correctional center until he testifies, but not for a longer period than sixty days. Notwithstanding the serving of the term of such commitment by any person, the commissioner may proceed in all respects with such inquiry and examination as if the witness had not previously been called upon to testify. Officers who serve subpoenas issued by the commissioner or under his authority and witnesses attending hearings conducted by him hereunder shall receive fees and compensation at the same rates as officers and witnesses in the courts of this state, to be paid on vouchers of the commissioner on order of the Comptroller from the appropriation for the administration of this chapter. (1969, P.A. 297; June, 1969, P.A. 1, S. 31; June, 1971, P.A. 8, S. 14; P.A. 78-280, S. 2, 127.)

Conn. Gen. Stat. § 12-511 Deficiency assessments.

12-511. Deficiency assessments. (a) After a final return in due form is filed, the commissioner shall cause the same to be examined and may make such further audit or investigation or reaudit as he may deem necessary, and if therefrom he shall determine that there is a deficiency with respect to the payment of any tax due under this chapter, he shall assess or reassess the additional taxes, penalties and interest due to this state, give notice of such assessment or reassessment to the taxpayer, and make demand upon him for payment. Within sixty days of the mailing of such notice, the taxpayer shall pay to the commissioner, in cash or by check, draft or money order drawn to the order of the Commissioner of Revenue Services, the amount of the deficiency. Such amount shall bear interest at the rate of one and one-fourth per cent per month or fraction thereof from the date when the original tax became due and payable. When it appears that any part of the deficiency for which a deficiency assessment is made is due to negligence or intentional disregard of the provisions of this chapter or regulations promulgated thereunder, there shall be imposed a penalty equal to ten per cent of the amount of such deficiency assessment. When it appears that any part of the deficiency for which a deficiency assessment is made is due to fraud or intent to evade the provisions of this chapter or regulations promulgated thereunder, there shall be imposed a penalty equal to twenty-five per cent of the amount of such deficiency assessment. No taxpayer shall be subject to more than one penalty under this section in relation to the same tax period. Any decision rendered by any federal court holding that a taxpayer has filed a fraudulent return with the Director of Internal Revenue shall subject the taxpayer to a penalty imposed by the preceding sentence without the necessity of further proof thereof, except when it can be shown that the return to the state so differed from the return to the federal government as to afford a reasonable presumption that the attempt to defraud did not extend to the state. (b) Except in the case of a wilfully false or fraudulent return with intent to evade the tax, no assessment of additional tax shall be made after the expiration of more than three years from the date of the filing of a return or from the original due date of a return, whichever is later; provided, where no return has been filed as provided by law, the tax may be assessed at any time. Where, before the expiration of the period prescribed herein for the assessment of an additional tax, a taxpayer has consented in writing that such period may be extended, the amount of such additional tax due may be determined at any time within such extended period. The period so extended may be further extended by subsequent consents in writing before the expiration of the extended period. (June, 1969, P.A. 1, S. 32; June, 1971, P.A. 8, S. 15; P.A. 80-307, S. 27, 31; P.A. 81-64, S. 18, 23; 81-411, S. 37, 42; P.A. 87-84, S. 2, 4; P.A. 88-314, S. 43, 54; P.A. 91-236, S. 12, 25.)

(a) related to failure to pay tax when due by eliminating the minimum penalty requirement in the amount of $50; P.A. 88-314 amended Subsec.

Any individual whose return to the Director of Internal Revenue has been amended in any respect affecting the tax imposed under this chapter shall, within ninety days after having filed such amended return, make an amended return to the commissioner. The time for filing such affidavit or amended return may be extended by the commissioner upon due cause shown. Notwithstanding the limitation of time in subsection (b) of section 12-511, if, upon examination, the commissioner finds that such taxpayer is liable for the payment of an additional tax, he shall, within a reasonable time from the receipt of an amended return or affidavit, notify such taxpayer of the amount of such additional tax, together with interest thereon computed at the rate of one and one-fourth per cent per month or fraction thereof from the date when the original tax became due and payable. Within thirty days of the mailing of such notice, the taxpayer shall pay to the commissioner the amount of such additional tax and interest. If, upon examination of such amended return or affidavit and related information, the commissioner finds that the taxpayer has overpaid the tax due the state, the commissioner shall certify the amount of such overpayment to the Comptroller, and such amount shall be paid to the taxpayer by the State Treasurer upon order of the Comptroller. (P.A. 74-63, S. 3, 5; P.A. 77-614, S. 139, 610; P.A. 84-423, S. 3.)

12-512. Collection of tax, penalties and interest. The amount of any tax, penalty or interest due and unpaid under the provisions of this chapter may be collected under the provisions of section 12-35. The warrant therein provided for shall be signed by the commissioner or his authorized representative. The amount of any such tax, penalty and interest shall be a lien, from the last day of the taxable year until discharged by payment, against all real estate of the taxpayer within the state, and a certificate of such lien signed by the commissioner may be filed for record in the office of the clerk of any town in which such real estate is situated, provided no such lien shall be effective as against any bona fide purchaser or qualified encumbrancer of any interest in any such property. When any tax with respect to which a lien has been recorded under the provisions of this section has been satisfied, the commissioner, upon request of any interested party, shall issue a certificate discharging such lien, which certificate shall be recorded in the same office in which the lien was recorded. Any action for the foreclosure of such lien shall be brought by the Attorney General in the name of the state in the superior court for the judicial district in which the property subject to such lien is situated, or, if such property is located in two or more judicial districts, in the superior court for any one such judicial district, and the court may limit the time for redemption or order the sale of such property or pass such other further decree as it judges equitable. (June, 1969, P.A. 1, S. 33; P.A. 78-280, S. 2, 4, 127; P.A. 85-501, S. 6.) History: P.A. 78-280 substituted “judicial district(s)” for “county(ies)”; P.A. 85-501 provided that lien shall be effective from the last day of the taxable year rather than last filing day of period for which taxpayer is delinquent and that such lien shall not be effective against a qualified encumbrancer as defined in Sec. 12-35b, deleting reference to purchasers and encumbrancers to whom property is transferred between last day of delinquency period and date of recording lien.

12-514. Excess payments. If, within three years after the due date of any return, the commissioner determines that any amount, penalty or interest has been paid more than once or has been erroneously or illegally collected or computed, the commissioner shall credit the excess amount collected or paid against any amounts then due and payable from the person under this chapter or any other chapter administered by the commissioner and the balance shall be refunded, upon order of the Comptroller, to the person or his successors, administrators or executors or any other person legally responsible for the conduct of the affairs of the taxpayer. (June, 1969, P.A. 1, S. 35.)

Conn. Gen. Stat. § 12-515 Refund claims.

12-515. Refund claims. Any taxpayer who feels that he has overpaid any taxes due under this chapter may file a claim for refund in writing with the commissioner within three years from the due date for which such overpayment was made stating the specific grounds upon which the claim is founded. Not later than ninety days following receipt of such claim for refund the commissioner shall determine whether such claim is valid and if so, said commissioner shall notify the Comptroller of the amount of such refund and the Comptroller shall draw an order on the Treasurer in the amount thereof for payment to the taxpayer. To the amount of such refund there shall be added interest at the rate of three-fourths of one per cent for each month or fraction thereof which elapses between the ninetieth day following receipt of such claim for refund by the commissioner and the date of notice by the commissioner that such refund is due. Failure to file a claim within the time prescribed in this section constitutes a waiver of any demand against the state on account of overpayment. Within thirty days after disallowing any claim in whole or in part the commissioner shall serve notice of his action on the claimant. (June, 1969, P.A. 1, S. 36; P.A. 85-356, S. 7, 9.)

Each such return shall be signed by the taxpayer, or by a guardian, receiver, referee, trustee, assignee or other fiduciary or any officer or agent appointed by any court to conduct the business or conserve the assets of any taxpayer.
