Montana EV Fees and Incentives (2026)
Montana adds $130 a year for an electric car and $70 for a plug-in hybrid under 6,000 lb, more for heavier vehicles; hybrids pay nothing extra. Cars 11+ years old on permanent registration pay a one-time fee instead, and amounts are not indexed.
No state-funded rebate or tax credit for buying an electric car is open in Montana as of October 2026; check your electric utility for local rebates.
The federal clean vehicle tax credits (up to $7,500 for a new EV, up to $4,000 for a used EV, and the commercial clean vehicle credit) ended for vehicles acquired after September 30, 2025. A vehicle still qualifies if a binding written contract was signed and a payment made by that date, even if it was delivered later; the credit is then claimed for the year of delivery.
