A 1980 law ties a portion of Kentucky's gasoline tax to the average wholesale price of gasoline in the state. That price has dropped in recent months, and the gasoline tax is scheduled to drop 4 cents/gallon on April 1st; however, the state legislature is considering amending the law to prevent this drop. It is estimated that tax decrease would result in $120 million decline in gasoline tax revenue.
