Sen. Cohen Welcomes Diesel Tax Cut

HARTFORD – State Senator Christine Cohen, Senate Chair of the Transportation Committee, welcomes news that the state diesel tax will fall by 7% beginning July 1. Each year, the Connecticut Department of Revenue Services determines the diesel tax using a formula linking the tax to the wholesale cost of diesel fuel.

This year, the diesel tax will fall from 52.4 cents per gallon, to 48.9 cents – a 3.5 cent per gallon reduction.

“This tax cut comes at a critical time when the economy is facing much uncertainty between conflict in the Middle East that could affect oil prices and the administration’s on-again-off-again trade wars,” said Sen. Cohen. “This decrease will provide some relief on operating costs for businesses, the trucking industry in particular, and I am hopeful that relief will be shared with consumers.”

In 2023, Senator Cohen voted alongside many of her colleagues to freeze the expected diesel tax increases.
