Idaho EV Incentives: Full Breakdown for 2026
Annual registration fee: Idaho charges EV owners an extra $140/year on top of standard registration, meant to replace the gas tax revenue EVs don't pay. This is a recurring annual cost, not one-time — worth weighing against any purchase rebate over your ownership period.
Registration fee source: Tax Foundation, "Electric Vehicle Tax Treatment by State, 2026" (published Aug 2026, data as of July 2026).
Idaho does not offer a state-level EV rebate or tax credit. Idaho EV buyers qualify for the federal IRS credit only. Idaho Power and Rocky Mountain Power offer utility-level EV incentive programs and time-of-use rates for EV owners.
Before October 1, 2025, Idaho EV buyers could get a federal credit of up to $7,500 for new EVs and $4,000 for used EVs. That credit has now expired for new purchases.
Federal EV Tax Credit: What Idaho Buyers Need to Know (Expired Oct 2025)

- New EV credit (expired): Was up to $7,500 for qualifying new battery electric vehicles bought before Oct 1, 2025.
- Used EV credit (expired): Was up to $4,000 for qualifying used EVs bought before Oct 1, 2025 from a licensed dealer, if the sale price was under $25,000.
- Income limits (new EV): $150,000 single / $225,000 head of household / $300,000 married filing jointly.
- Income limits (used EV): $75,000 single / $112,500 head of household / $150,000 married filing jointly.
- MSRP caps: $55,000 for sedans and wagons; $80,000 for SUVs, crossovers, vans, and trucks.
- Point-of-sale transfer: Since Jan 1, 2024, you can apply the credit as an instant dealer discount rather than waiting until tax filing.
Additional Idaho EV Programs & Utility Incentives
Idaho Power offers a $400 rebate for Level 2 EV charger installation and an EV time-of-use rate. Rocky Mountain Power also has EV incentive programs.
Always check with your local electric utility, as additional rebates for home EV charging equipment can add hundreds more in savings on top of vehicle incentives.
