Idaho Laws and Incentives

Listed below are the summaries of all current Idaho laws, incentives, regulations, funding opportunities, and other initiatives related to alternative fuels and vehicles, advanced technologies, or air quality. You can go directly to summaries of:

State Incentives

Plug-In and Hybrid Electric Vehicle Exemption from Vehicle Testing Requirements

Electric vehicles, plug-in hybrid electric vehicles, and hybrid electric vehicles are exempt from state motor vehicle inspection and maintenance programs. For more information, see the Idaho Vehicle Inspection Program website. (Reference Idaho Statutes 39-116B)

License Exemptions for Biodiesel Production for Personal Use

A biodiesel producer that produces up to 5,000 gallons of biodiesel fuel in a calendar year for personal consumption is exempt from the requirement to obtain an Idaho motor fuel distributor's license. (Reference Idaho Statutes 63-2427A)

Alternative Fuels Tax Exemption and Refund for Government Fleet Vehicles

State excise tax does not apply to special fuels, including gaseous special fuels, when used in state or federal government owned vehicles. Special fuels include natural gas, propane, hydrogen, and fuel suitable for use in diesel engines. In addition, state excise tax paid on special fuels used in state or federal government vehicles is subject to a refund, as long as the tax was originally paid directly to a special fuel vendor. The tax refund is not available for special fuels used while idling. Idling means a period of time greater than 15 minutes when the motor vehicle is stationary with the engine operating. (Reference Idaho Statutes 63-2401, 63-2402, and 63-2423)

Utility/Private Incentives

Electric Vehicle Supply Equipment (EVSE) Rebate - Yellowstone-Teton Clean Cities (YTCC)

YTCC offers a rebate of $5,000 toward the purchase of publicly accessible EVSE. Eligible entities include businesses and municipalities in the communities surrounding Grand Teton National Park and Yellowstone National Park. Rebates are offered on a first-come, first-served basis. For more information, see the YTCC Vehicle and Infrastructure Rebates website.

Laws and Regulations

Regional Electric Vehicle (REV) West Plan

Idaho joined Arizona, Colorado, Montana, Nevada, New Mexico, Utah, and Wyoming (Signatory States) in signing the REV West memorandum of understanding (MOU) to create an Intermountain West Electric Vehicle (EV) Corridor that will make it possible to seamlessly drive an EV across the Signatory States' major transportation corridors. Signatory States are committed to:

  • Create best practices and procedures that will enhance EV adoption by: promoting EV consumer acceptance and awareness by addressing range anxiety, coordinating on EV charging station locations, and leveraging economies of scale;
  • Create minimum standards for EV charging stations, including standards for administration, interoperability, operations, and management;
  • Identify and develop opportunities to incorporate EV charging stations into planning and development processes such as building codes, metering policies, and renewable energy generation projects;
  • Encourage EV manufacturers to stock and market a wide variety of EVs within the Signatory States; and
  • Identify, respond to, and collaborate on funding opportunities to support the development of the Plan.
The Signatory States have formed a Coordination Group composed of senior leadership from each state which will meet on a quarterly basis and report on the above actions. A final report will be completed by April 1, 2018.

Electric Vehicle Supply Equipment Regulation Exemption

Individuals, corporations, or other legal entities that sell electricity for the purpose of charging plug-in electric vehicles are not under the jurisdiction of the Idaho Public Utility Commission (PUC), but instead subject to Orders or Rules of the PUC. (Reference Idaho Statutes 61-119)

State Agency Petroleum Reduction Plan

All state agencies must reduce their fleets' petroleum consumption by increasing vehicle fuel economy and operating efficiency and reducing the number of miles driven by each employee. Agencies must also give priority to the purchase and use of hybrid electric vehicles and other fuel-efficient, low emission vehicles. (Reference Executive Order 2007-21)

Propane Dealer Requirements

Propane dealers must meet education, experience, and examination qualifications, and hold a valid individual license. Each propane fueling facility must be licensed. A fee of up to $500 is required for each license application, original license, and annual license renewal. (Reference Idaho Statutes 54-5301 to 54-5317)

Biodiesel Definition

Biodiesel is defined as any fuel derived in whole or in part from agricultural products, animal fats, or the wastes from these products, and is suitable for use in diesel engines. A biodiesel blend is defined as any fuel produced by blending biodiesel with petroleum-based diesel to produce a fuel suitable for use in diesel engines. (Reference Idaho Statutes 63-2401)

Ethanol Blended Fuel Definition

Ethanol blended fuel, such as gasohol, is defined as any gasoline blended with 10% or more of anhydrous ethanol. (Reference Idaho Statutes 63-2401)

Plug-In Electric Vehicle Fee

In addition to standard registration fees, plug-in electric vehicle owners must pay an annual fee of $140 and plug-in hybrid electric vehicle owners must pay an annual fee of $75. Neighborhood electric vehicles are exempt from the fee. (Reference House Bill 20, 2017, and Idaho Statutes 49-402 and 49-457)

Natural Gas Tax

Compressed natural gas used as a special motor fuel is subject to the state fuel excise tax rate of $0.32 per gasoline gallon equivalent, measured at 5.66 lbs. or 126.67 cubic feet at a base temperature of 60 degrees Fahrenheit and a pressure of 14.7 lbs. per square inch. Liquefied natural gas is also subject to the excise tax rate of $0.349 per diesel gallon equivalent, measured at 6.06 lbs. (Reference Idaho Statutes 63-2402 and 63-2424)

Neighborhood Electric Vehicle (NEV) Access to Roadways

An NEV is defined as a self-propelled, electrically-powered, four-wheeled motor vehicle that does not produce emissions and conforms to the definition and requirements for low-speed vehicles specified in Title 49 of the Code of Federal Regulations, section 571.500. An NEV must be titled, registered, and insured according to state law and may only be operated by a licensed driver. NEVs may not be driven on any highway with a speed limit greater than 35 miles per hour (mph), or across any highway with a speed limit greater than 45 mph. (Reference Idaho Statutes 49-115, 49-123, 49-402, and 49-663)
