2023 Connecticut General Statutes › Title 12 - Taxation › Chapter 221 - Motor Vehicle Fuels Tax › Section 12-458h. - Calculation of rate of tax to be imposed on the sale or use of diesel fuel.

(a)(1) The Commissioner of Revenue Services shall, on or before June 15, 2008, and on or before the fifteenth day of June thereafter, calculate, in accordance with subsection (b) of this section, the applicable tax rate per gallon of diesel fuel on the sale or use of such fuel during the twelve-month period beginning on the next succeeding July first, and shall notify each distributor, the chairpersons and ranking members of the joint standing committee of the General Assembly having cognizance of matters relating to finance, revenue and bonding, and the Secretary of the Office of Policy and Management of such applicable tax rate.
(2) The commissioner shall, on or before June 15, 2008, and on or before the fifteenth day of June thereafter, determine the average wholesale price per gallon of diesel fuel in this state during the twelve-month period ending on the next preceding March thirty-first by using wholesale price information for diesel fuel published by the Oil Price Information Service. Such wholesale price information for “Hartford/Rocky Hill” and “New Haven” shall be averaged by the commissioner. If either the first or last day of such twelve-month period falls on a Sunday or a legal holiday, as defined in section 1-4, the next succeeding day which is not a Sunday or legal holiday shall be substituted for such first or last day, as the case may be.
(b) (1) The applicable tax rate per gallon of diesel fuel shall be the sum of (A) the fixed rate per gallon, as defined in this subdivision, and (B) the product calculated in accordance with subdivision (2) of this subsection. The sum shall be rounded to the nearest one-tenth of a cent. For purposes of this subdivision, “the fixed rate per gallon” on the sale or use of diesel fuel during the twelve-month period beginning on the first day of July in 2008, 2009 and 2010 is twenty-six cents, and on the sale or use of diesel fuel during the twelve-month period beginning on the first day of July in 2011, and each year thereafter, is twenty-nine cents.
(2) The commissioner shall multiply (A) the average wholesale price per gallon of diesel fuel, as determined in accordance with subdivision (2) of subsection (a) of this section, by (B) the tax rate specified in subdivision (1) of subsection (b) of section 12-587. The tax rate so specified shall be the tax rate in effect for the twelve-month period beginning on the next succeeding July first.
(c) For purposes of subdivision (1) of subsection (a) of section 12-459, the tax provided for by section 12-458 shall, if determined by the commissioner to be eligible for refund, be refunded at the tax rate per gallon specified in subdivision (1) of subsection (b) of this section.
