Your complete guide to Idaho EV tax credits and rebates in 2025

If you're considering switching to an electric vehicle (EV) in Idaho, you'll find a growing network of support for electric driving. While Idaho doesn't have its own state EV tax credit like some other states, utility companies have stepped up with meaningful rebates and programs that put cash directly back in your pocket.

From utility rebates for EV chargers to time-of-use electricity rates that significantly reduce charging costs, Idaho has created incentive programs that make electric vehicle ownership more accessible and affordable. We'll walk you through every available program—federal, utility, and local—and help you understand how to maximize your savings while going electric in the Gem State.

Idaho doesn't offer financial incentives for EV purchases. However, some utility companies offer rebates for EV charger installations, providing direct cash back regardless of your tax situation.

Home charging transforms your EV ownership experience and saves serious money. While public charging can cost $0.37 per kWh, home charging typically runs $0.13 per kWh in Idaho. 

Idaho utilities recognize that widespread EV adoption depends on convenient home charging, which is why several utilities across the state offer substantial charger incentives designed to make home charging accessible even for houses that need electrical upgrades.

Utility EV charger rebate programs

One utility provider in Idaho offers an EV charger rebate program: Kootenai Electric Cooperative offers homeowners an EV charger rebate of up to $350 toward the purchase of an at-home Level 2 charger.

The cooperative also offers custom rebates for businesses, so contact them to inquire about rebates for your commercial EV charging station installation.

Idaho electrical panel upgrade considerations

Most EV chargers require a 240-volt circuit, and older homes—especially Idaho homes built before 1980—often need electrical panel upgrades to handle the additional load safely. These homes typically have 100-amp electrical panels that struggle with modern electrical demands, let alone adding a 40-amp EV charger. If your electrical panel lacks sufficient capacity, expect to pay between $1,500 and $4,000 for an upgrade.

While Idaho utilities don't offer specific electrical panel rebates like some other states, the substantial EV charger rebates help offset total installation costs. 

Before installing an EV charger, have a qualified electrician assess your electrical panel's capacity. Many utility rebate programs require this assessment anyway, and it ensures your home can safely handle the additional electrical load.

Time-of-use rates and smart charging incentives

Smart EV owners charge when electricity is cheapest. Several Idaho utilities offer special time-of-use rates for EV owners, which can significantly cut your charging costs compared to standard residential rates.

Here are some standout time-of-use programs:

• Idaho Power customers can save on EV charging by enrolling in the utility's seasonal time-of-use rate. In the summer, you'll pay $0.24 per kWh from 7 p.m. to 11 p.m., $0.12 per kWh from 3 p.m. to 7 p.m., and only $0.06 per kWh if you charge from 11 p.m. to 3 p.m. During the winter, you'll pay $0.12 per kWh from 6 a.m. to 9 a.m. and from 5 p.m. to 8 p.m. Outside of these hours, you'll pay $0.08 per kWh.

• Riverside Electric Cooperative uses a flexible pricing model where energy charges add up to a flat rate you pay for service. Your energy charge fluctuates based on the time of day, so charging your EV during mid-peak or off-peak times will reduce your bill. Off-peak hours last from 11 p.m. to 6 a.m. year-round and come with an energy charge of $0.10 per kWh. On-peak hours begin at 4 p.m. and end at 7 p.m. in the winter and have a wintertime energy charge of $0.14 per kWh. 

• Rocky Mountain Power's time-of-use plan uses seasonal time-based pricing. You'll pay $0.14 per kWh from May to October between 8 a.m. and 11 p.m. and drop to $0.05 per kWh at night. Between November and April, electricity will cost $0.12 per kWh from 7 a.m. to 10 p.m. and only $0.04 per kWh at night.

Most modern EVs and home chargers can be programmed to automatically start charging during off-peak hours, making these savings completely hands-off once you set them up.

According to data from the Alternative Fuels Data Center, Idaho has approximately 219 public charging stations statewide as of September 2025, including 627 public charging ports. Of those publicly available chargers, 376 are Level 2 stations, and 251 are DC fast chargers.

Where to find public charging stations

The state continues investing in charging infrastructure to support growing EV adoption. Stations are rapidly appearing along highways to make longer trips more convenient, with most charging options located in Boise. 

Public charging costs and economics

Public charging in Idaho averages $0.37 per kWh. Many networks now use variable pricing that accounts for location, time of day, and power delivery, so costs can fluctuate throughout the day.

Level 2 public charging typically costs less but charges more slowly, making it better suited for longer stops like shopping or dining.

Idaho makes going electric more practical through utility programs that emphasize long-term savings. By combining utility rebates—and pairing your EV with solar panels—you can reduce both installation costs and ongoing charging expenses. Time-of-use electricity rates and bundled incentives from local utilities add real value, especially when projects are planned together. With affordable electricity, utility support, and growing interest in home electrification, Idaho offers a straightforward path to electric vehicle ownership that’s both cost-effective and future-focused.
