House Joint Resolution No. 2025HJ0008.2 requests an interim study by the Legislative Council to evaluate the current system of electric vehicle registration fees and taxation in Montana. The resolution highlights the growing gap in transportation infrastructure funding due to stagnant motor fuel tax revenues, inflation, and the increasing prevalence of fuel-efficient vehicles. It notes that electric vehicles, which constituted about 0.5% of Montana's vehicle registrations in 2022, contribute minimally to road funding, yet owners face additional registration fees and taxes that exceed those of traditional internal combustion engine vehicles by an average of $152.46 annually. The resolution emphasizes the need for a fairer approach to road funding that does not disproportionately penalize electric vehicle owners.

The study will involve comparing the fairness of registration fees and taxation methods for electric vehicles versus high-efficiency gas-powered vehicles, as well as reviewing tax structures from other states. The bill removes the previous requirement for the committee to design a new equitable taxation system for all fuel types and eliminates the directive to appoint a subcommittee with specific non-legislative members. The final results of the study, including findings and recommendations, are to be reported to the 70th Legislature by September 15, 2026.
