Alternative Fuel Heavy-Duty Vehicle Tax Credit Program

The state provides an income tax credit for the qualified purchase of a natural gas, a 100% electric, or a hydrogen-electric heavy-duty vehicle which is defined in 59-7-618.1 and 59-10-1033.1 UCA as a commercial category 7 or 8 vehicle that has never been titled or registered. Class 7 and Class 8 vehicles are classified by the gross vehicle weight rating, which is also known as their GVWR. A Class 7 vehicle has a GVWR between 26,001 and 33,000 pounds. A Class 8 vehicle has a GVWR higher than 33,000 pounds. These vehicles usually have three axles, but some will have five axles in order to haul a trailer with substantial weight on it. Some examples would be a 5-axle tractor-trailer (Semi or 18-wheeler), cement trucks, dump trucks, and refuse haulers. Operators of Class 7 and 8 trucks must have a commercial driver’s license, also called a CDL.

The Utah Legislature authorized the credit during the 2021 General Session for tax year 2021 through 2030. The following table shows the tax credit for each tax year.
