Connecticut diesel tax decreases July 1

Effective July 1, 2016, Connecticut’s per-gallon diesel fuel tax rate will decrease to 41.7 cents per gallon, which is down from the current rate of 50.3 cents per gallon. The state diesel tax rate is comprised of two components. One is a base rate of 29 cents per gallon. The second component is calculated annually, and is based upon the average wholesale price per gallon of diesel fuel from the period of April 1 through March 30, plus the applicable gross receipts tax rate on petroleum products. Since the average wholesale price was lower for this twelve-month period that the previous twelve-month period, the variable component of the diesel tax rate will go down.
