Conference committee frames mileage-based user fee for EVs as interim step toward broader application

At a Senate-House conference committee meeting on the T bill, members discussed adding intent language stating the mileage-based user fee for battery electric vehicles would be an interim step toward applying a mileage-based fee to all motor vehicles once state fuel taxes are eliminated.

The committee noted the language was intended to clarify long-term goals for vehicle fees and to address concerns among EV drivers that a new fee would single out their vehicles. A staff member summarized the proposed wording: "it would read ... mileage based user fee for BEV pleasure cars will be an interim step towards gradually expanding the mileage based user fee to all motor vehicles upon elimination of the state fuel taxes." The same staff member said the agency has described EVs as the initial cohort and that the long-term goal is to cover every vehicle under the mileage-based approach.

Lawmakers and staff also discussed public perception and fairness. One participant said that concerns about fee fairness for drivers who purchase fuel in one state but drive in another apply both to a gas tax and to any mileage-based program. Another participant noted earlier estimates of potential revenue for the mileage-based program had been discussed but labeled those as speculative.

Committee members agreed the intent language should make clear this is a transition mechanism and not a permanent, EV-only levy. They planned to circulate a written draft and return to the topic in a later meeting.

The committee did not take a formal vote on the final statutory language during this meeting.
