Sec. 12-480. Credit on tax. Refund. Challenging legality of registration fee. (a) Every such motor carrier shall be entitled to a credit on such tax equivalent to the rate per gallon of the tax in effect under said chapter 221 on all motor fuel purchased by such carrier within this state for use in its operations either within or without this state and upon which motor fuel the tax imposed by the laws of this state has been paid by such carrier. Evidence of the payment of such tax in such form as may be required by, or is satisfactory to, the Commissioner of Revenue Services shall be furnished by each such carrier claiming the credit herein allowed. When the amount of the credit herein provided to which any motor carrier is entitled for any quarter exceeds the amount of the tax for which such carrier is liable for the same quarter, such excess may, under regulations of the Commissioner of Revenue Services, be allowed as a credit on the tax for which such carrier would be otherwise liable for any of the four succeeding quarters; or such carrier may file, within one year from the due date for such quarter, an application verified and presented, in accordance with regulations adopted by the Commissioner of Revenue Services in accordance with chapter 54 and supported by such evidence as may be satisfactory to the Commissioner of Revenue Services, for a refund of such excess.

(b) (1) The Commissioner of Revenue Services shall not allow such refund except after an audit of the applicant's records and he shall audit the records of an applicant at least once a year. The commissioner shall transmit all claims approved by him to the Comptroller, who shall draw an order on the State Treasurer for payment of such refund. If the commissioner determines that any such claim is not valid, either in whole or in part, he shall mail notice of the proposed disallowance to the claimant, which notice shall set forth briefly the commissioner's findings of fact and the basis of disallowance in each case decided in whole or in part adversely to the claimant. Sixty days after the date on which it is mailed, a notice of proposed disallowance shall constitute a final disallowance except only for such amounts as to which the claimant has filed, as provided in subdivision (2) of this subsection, a written protest with the Commissioner of Revenue Services.

(2) On or before the sixtieth day after the mailing of the proposed disallowance, the claimant may file with the commissioner a written protest against the proposed disallowance in which the claimant sets forth the grounds on which the protest is based. If a protest is filed, the commissioner shall reconsider the proposed disallowance and, if the claimant has so requested, may grant or deny the claimant or the claimant's authorized representatives an oral hearing.

(3) The commissioner shall mail notice of his determination to the claimant, which notice shall set forth briefly the commissioner's findings of fact and the basis of decision in each case decided in whole or in part adversely to the claimant.

(4) The action of the commissioner on the claimant's protest shall be final upon the expiration of one month from the date on which he mails notice of his action to the claimant unless within such period the claimant seeks judicial review of the commissioner's determination pursuant to subsection (b) of section 12-489.

(c) (1) Any motor carrier who has registered any vehicle and paid a fee pursuant to section 12-487, and who claims that such registration or payment is illegal for any reason, may claim a refund or credit, in writing, within six months after such registration or payment. If, upon examination of such claim, the commissioner determines that such registration or payment was illegal, the State Treasurer, upon order of the Comptroller, shall refund or credit the amount of any such fee to such motor carrier. If the commissioner determines that registration or payment was legal, he shall mail notice of the proposed disallowance to the motor carrier, which notice shall set forth briefly the commissioner's findings of fact and the basis of disallowance in each case decided in whole or in part adversely to the claimant. Sixty days after the date on which it is mailed, a notice of proposed disallowance shall constitute a final disallowance except only for such amounts as to which the claimant has filed, as provided in subdivision (2) of this subsection, a written protest with the commissioner.

(2) On or before the sixtieth day after the mailing of the proposed disallowance, the claimant may file with the commissioner a written protest against the proposed disallowance in which the claimant sets forth the grounds on which the protest is based. If a protest is filed, the commissioner shall reconsider the proposed disallowance and, if the claimant has so requested, may grant or deny the claimant or the claimant's authorized representatives an oral hearing.

(3) The commissioner shall mail notice of his determination to the claimant, which notice shall set forth briefly the commissioner's findings of fact and the basis of decision in each case decided in whole or in part adversely to the claimant.

(4) The action of the commissioner on the claimant's protest shall be final upon the expiration of one month from the date on which he mails notice of his action to the claimant unless within such period the claimant seeks judicial review of the commissioner's determination pursuant to subsection (b) of section 12-489.

(c) providing for a credit or refund of any registration fee challenged as being illegal, effective June 29, 1981; P.A. 90-140 amended Subsec. (a) by eliminating the requirement that to be eligible for refund the carrier must have incurred liability in another state under a similar tax and that the refund may not exceed the tax liability to such other state calculated at a rate not in excess of the rate of motor fuel tax in effect in Connecticut, effective January 1, 1991, and applicable to refunds under Sec. 12-480 on or after that date; P.A. 97-243 amended Subsecs. (b) and (c) to provide for an administrative hearing with the department before taking an appeal to the Superior Court, to establish the time for filing a claim and to make technical changes, effective July 1, 1997, and applicable to claims for refund filed on or after said date.

As long as the bond remains in force, the Commissioner of Revenue Services may order refunds to the motor carrier in the amounts appearing to be due on applications filed by the carrier under section 12-480 without first auditing the records of the carrier. The surety shall be liable for all omitted taxes assessed against the carrier, including the penalties and interest on such taxes provided in section 12-488, even though the assessment is made after cancellation of the bond, but only for such taxes due and payable while the bond was in force and penalties and interest on such taxes.

The amount of motor fuel used in the operations of any motor carrier within this state shall be such proportion of the total amount of such motor fuel used in its entire operations within and without this state as the total number of miles traveled within this state bears to the total number of miles traveled within and without this state. The commissioner may, at his discretion, allow use of a miles per gallon factor in computing fuel used in operations in lieu of the above formula if evidence is presented to his satisfaction that no loss of revenue will result. The commissioner may hold the lessor and lessee of vehicles used by such motor carrier jointly and severally responsible for the payment of the tax set forth in this section.

(a) Two or more motor carriers regularly engaged in the transportation of passengers on through buses on through tickets in pool service may, at their option, make joint reports of their entire operations in this state. The taxes imposed by section 12-479 shall be calculated on the basis of such joint reports as though such carriers were a single carrier; and the carriers making such reports shall be jointly and severally liable for the taxes.

(b) Such joint reports shall show the total number of over-the-road miles traveled in this state and the total number of gallons of motor fuel purchased in this state by the reporting carriers. Credits to which the carriers making a joint return are entitled shall not be allowed as credits to any other carrier; but carriers filing joint reports shall permit all carriers engaged in this state in pool operations with them to join in filing joint reports.

The commissioner may disclose to any official of another jurisdiction that is a party to the agreement the location of offices, motor vehicles and other real and personal property of motor carriers.

(6) An agreement entered into under this subsection may provide for each jurisdiction that is a party to the agreement to audit the records of licensees based in such jurisdiction to determine if the motor fuel taxes due each jurisdiction are properly reported and paid. Each jurisdiction that is a party to the agreement shall forward the findings of the audits performed on licensees based in such jurisdiction to each other jurisdiction that is a party to the agreement in which the carrier has taxable use of motor fuels. Such findings may be served upon the licensee and shall have the same effect as the audit findings made by the department.

(7) No agreement entered into under this subsection may preclude the department from auditing the records of any motor carrier who has used motor fuels in this state. Any licensee or motor carrier who is eligible to be a licensee from whom the department has requested records shall make the records available at the location designated by the department or may request the department to audit such records at the place of business of such licensee or motor carrier.

Sec. 12-486a. Deficiency assessments by commissioner. (a) If the Commissioner of Revenue Services is not satisfied with any report or return of a motor carrier subject to the tax imposed by this chapter or the amount of such tax to be paid by any such motor carrier, the commissioner may compute and assess the amount of such tax on the basis of facts contained in such report or return or on the basis of any other information available to the commissioner. One or more deficiency assessments may be made with respect to any return for the tax imposed by this chapter.

(c) 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, or fifty dollars, whichever is greater. 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 of twenty-five per cent of the amount of such deficiency assessment. No taxpayer shall be subject to more than one penalty under this subsection in relation to the same tax period.

(d) The Commissioner of Revenue Services shall give written notice to any motor carrier of any such deficiency assessment. If such notice is served by mail, it shall be addressed to such motor carrier at the address appearing in the records of the Department of Revenue Services. Except in the case of fraud, intent to evade the provisions of this chapter or failure to submit a return, such notice of a deficiency assessment shall be mailed within three years after the last day of the month following the quarterly period for which the amount is assessed or within three years after the return for such period is filed, whichever is later.

(e) If, prior to the expiration of the time prescribed in subsection (d) of this section for the mailing of notice of a deficiency assessment, the taxpayer has consented in writing to the mailing of notice after such time, the notice may be mailed at any time prior to the expiration of the period agreed upon for such mailing. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of such period.

(a) If any motor carrier fails to pay tax reported to be due on its report within the time specified under the provisions of this chapter, there shall be imposed a penalty of ten per cent of such amount of tax due and unpaid, or fifty dollars, whichever is greater. The tax shall bear interest at the rate of one per cent per month or fraction thereof, from the due date of such tax until the date of payment. If no return has been filed within one month after the time specified under the provisions of this chapter, the commissioner may make such return at any time thereafter, according to the best information obtainable and the form prescribed.

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 is 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 make such other or further decree as it judges equitable.

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 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 the commissioner 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 the commissioner's own initiative and require the taxpayer or any individual whom the commissioner believes to be in possession of relevant information concerning the taxpayer to appear before the commissioner or the commissioner's authorized agent with any specified books of account, papers or other documents, for examination under oath.

Such citation shall be signed by the same authority, and such appeal shall be returnable at the same time and served and returned in the same manner, as is required in case of a summons in a civil action. The authority issuing the citation shall take from the appellant a bond or recognizance to the state of Connecticut, with surety, to prosecute the appeal to effect and to comply with the orders and decrees of the court in the premises. Such appeals shall be preferred cases, to be heard, unless cause appears to the contrary, at the first session, by the court or by a committee appointed by it. Said court may grant such relief as may be equitable and, if any tax or fee has been paid prior to the granting of such relief, may order the Treasurer to pay the amount of such relief, with interest at the rate of two-thirds of one per cent per month or fraction thereof to the aggrieved motor carrier. If the appeal has been taken without probable cause, the court may tax double or triple costs, as the case demands; and, upon all such appeals which are denied, costs may be taxed against the appellant at the discretion of the court, but no costs shall be taxed against the state.
