Idaho Tax Incentives
Biofuel Fueling Infrastructure Tax Credit
Qualified biofuel fueling infrastructure is eligible for a credit of up to 6% of the qualified investment against the corporate income tax. The allowable credit cannot exceed 50% of the taxpayer's income tax liability. For the purpose of this incentive, biofuel is defined as any fuel offered for sale as a transportation fuel that is agriculturally derived and meets applicable ASTM standards including, but not limited to, ethanol, ethanol blended fuels, biodiesel, and biodiesel blended fuels. This incentive expires December 31, 2011. (Reference Idaho Statutes 63-3029M)
Alternative Fuels Tax
The motor fuel tax rate of $0.25 per gallon does not apply to special fuels dispensed into a motor vehicle that uses gaseous special fuels and displays a valid gaseous special fuels permit. Special fuels include compressed and liquefied natural gas, liquefied petroleum gas, hydrogen, and fuel suitable for use in diesel engines. The state excise tax on special fuels, determined on a gasoline gallon equivalent basis, still applies. Alternatively, an annual fee in lieu of the excise tax may be collected on a vehicle powered by gaseous special fuels, according to the gross vehicle weight rating of the vehicle. State government agencies are entitled to a refund of any special fuels tax paid to the vendor from which the fuel was purchased. No refund of special fuels tax shall be paid on special fuels used by a registered motor vehicle 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, 63-2423, and 63-2424)
