    Calculation of Credit Changed for New Motor Vehicle Purchases

    Act 403 changed the credit for purchases of new motor vehicles to ten percent of the cost of the qualified motor vehicle or $2,500, whichever is less, provided that the motor vehicle is registered in Louisiana.

    Changes EFFECTIVE JUNE 22, 2017

    Reduced Credit Amount for Conversions and Fueling Stations

    Act 325 permanently reduces the credit from 36 percent to 30 percent of the cost of the qualified clean-burning motor vehicle fuel property being purchased to (1) convert vehicles propelled by gasoline or diesel to an alternative fuel or (2) build fueling stations.

    Calculation of Credit Changed for New Motor Vehicle Purchases

    For new motor vehicles originally equipped to be propelled by an alternative fuel, Act 325 eliminates the option of determining the exact cost that is attributable to the alternative fuel property. Instead, the amount of the credit for purchases of new motor vehicles is now equal to 7.2 percent of the cost of the qualified motor vehicle or $1,500, whichever is less, provided that the motor vehicle is registered in Louisiana.

    New Registration and Use Requirements for Credits for Converted Commercial Vehicles

    Pursuant to Act 325, in order to be eligible for the credit for costs associated with converting a vehicle to alternative fuel usage, commercial vehicles must be registered and primarily used in Louisiana for four years after the date of the conversion. For purposes of this requirement, a commercial vehicle is deemed primarily used in Louisiana when 80% of the miles traveled in the four years after the conversion occurs in Louisiana.

    Qualified Costs for Fueling Stations Clarified

    Act 325 clarifies that the costs associated with fueling station infrastructure that are not directly related to the delivery of an alternative fuel into the fuel tank of motor vehicles are not eligible for the credit.

    The Louisiana Division of Administration must purchase dedicated alternative fuel vehicles (AFVs) capable of operating on natural gas or liquefied petroleum gas (propane), or bi-fuel vehicles capable of operating on conventional fuel or natural gas, propane, or any non-ethanol advanced biofuel. State agency vehicles may be granted a waiver if fueling stations are not available within a 25-mile radius, the agency cannot recoup the incremental cost of the vehicle within 60 months, or the available vehicles do not meet agency specifications. 

    Any AFV a state agency purchases or leases must have a minimum fuel economy of 18 miles per gallon (mpg) for city driving, 28 mpg for highway driving, or a combined city/highway average of 24 mpg. Law enforcement vehicles, certified emergency vehicles, and state agency vehicles with prior written authorization are exempt from this requirement.
