Wyoming Slashes EV Decal Fees 50% And Eliminates Charging Sales Tax

Wyoming’s electric vehicle owners are getting a break. The state passed HB0145, a new law that cuts EV fees and removes a sales tax on charging. Governor signed it into law on March 7, 2026. It takes effect July 1, 2026.

Wyoming just gave EV owners a break — cutting fees and eliminating the sales tax on charging.

The law cuts the annual registration fee for fully electric vehicles in half. It drops from $200 to $100. Plug-in hybrid owners also see relief, with their fee falling from $100 to $50. These fees exist to make up for fuel tax revenue the state doesn’t collect when drivers charge at home instead of pumping gas.

The law also ends a 4% sales tax on electricity used to charge EVs. Gasoline has long been exempt from sales tax in Wyoming. Now electricity used for vehicles gets the same treatment. This change removes what supporters called “triple taxation” on EV drivers.

Representative Mike Yin, a Wyoming Democrat and EV owner, proposed the bill. Amendments, including those reportedly from Senator Rothfuss, helped simplify how fuel taxes apply to EVs.

The law also sets up a clearer system for public charging stations. DC fast chargers, also called Level 3 chargers, now carry a 3.5 cents per kilowatt-hour tax. That rate matches Wyoming’s gas tax. Station owners must show the full price per kilowatt-hour, including taxes, to customers.

Level 2 chargers, which are slower and used more by residents, won’t have to collect that fuel tax. That’s expected to help keep those stations open and support the growth of charging options across the state.

The shift puts more of the tax burden on fast chargers. Those are mostly used by travelers passing through Wyoming. That means out-of-state drivers will now help pay for Wyoming’s roads.

Wyoming has a spread-out population and a lot of open space. Charging infrastructure there’s been a challenge. Supporters say this law helps fix a system that was unfair and was slowing EV growth. They’re calling it a win for both EV drivers and the state’s roads. This kind of state-level energy policy comes at a time when cross-border energy exchange between the U.S. and Canada faces uncertainty, amid reports of Ontario threatening tariffs that could raise electricity costs across multiple states. Wyoming currently has around 350 public EV chargers listed on PlugShare, reflecting how early-stage the state’s charging network remains.
