HARTFORD, Conn. (AP) – Connecticut’s diesel tax will increase by 9 cents per gallon on July 1 after a scheduled rate adjustment announced Wednesday by Governor Ned Lamont.
The tax, which is currently 40.1 cents per gallon, will rise to 49.2 cents per gallon, according to a letter from Lamont to the top Democrats and Republicans on the General Assembly Tax Drafting Committee and its budget director. . State law requires that it be updated annually, based on a complex formula calculated by the Department of Tax Services that takes into account daily fuel prices at two terminals over the previous 365 days. .
