For several years, residents of all states have been eligible to receive a federal tax credit of $7,500 for qualified EV purchases. However, this tax credit ends for vehicles purchased after September 30, 2025. Seventeen states offer an additional incentive beyond the federal credit, ranging from a $1,500 incentive in Rhode Island to a $7,500 credit in Oregon and Maine.
Contrary to a tax incentive, 40 states impose a higher annual vehicle registration fee for EVs and some hybrid vehicles to help offset forgone gas tax revenue. These fees range from $50 in Hawaii and South Dakota to $260 in New Jersey. These, however, have generally been justified as modest efforts to defray the lack of gas tax collections from EVs, which may be more environmentally friendly, but still put wear and tear on roads.
Eleven states both offer an incentive for the purchase of an EV and impose a higher registration fee for EVs than for combustion engine vehicles. The table below summarizes these policies.
Another response by states to backfill reductions in gas tax collections has been to implement a tax on EV charging stations. States like Georgia, Iowa, Kentucky, and Oklahoma impose a tax per kilowatt-hour distributed by charging stations. While this added user fee may help equalize treatment between combustion engines and EVs, because many users charge their EVs at home, these taxes can fail to fully account for EV road use.
Higher registration fees and EV charging station taxes are an attempt to better connect vehicle miles traveled (VMT) to transportation and road funding, yet in some instances, they are implemented in conflict with policies aimed at increasing EV adoption. A simpler transportation policy solution would be a VMT tax.
A VMT tax is levied on the number of miles traveled by an individual vehicle. This is usually done by odometer reading or through a GPS device. While there are privacy concerns with the use of GPS devices to track VMT, relying purely on odometer readings can result in drivers being charged for miles driven outside of the taxing state.
Moreover, as devices and apps used by insurance providers to track safe driving become commonplace, similar tools could be used to directly link the miles traveled to public road and infrastructure spending in the proper jurisdiction.
Currently, four states have active VMT tax programs:
Vermont was expected to begin a similar program in 2025, but implementation has been postponed to 2027. Additionally, California and Washington have run significant VMT pilot programs.
The state EV taxation landscape reflects the evolving transportation sector and the pressing need to address both fiscal gaps in road funding and environmental concerns. As the EV market continues to evolve and technology advances, it's likely that tax policies will also adapt.
