Alternative Fuel Vehicle (AFV) and Hybrid Electric Vehicle (HEV) Tax Credit

An income tax credit is available from the Colorado Department of Revenue for the incremental cost of purchasing an AFV or for the conversion of a vehicle to operate using an alternative fuel. HEVs also qualify for this incentive. This credit is only available in the year during which the vehicle was purchased or converted, and a vehicle may only qualify for this credit one time. For an AFV purchase or conversion that permanently replaces a motor vehicle or power source that is ten or more years old , the percentage specified in the table below is doubled, up to a maximum of 100% of the incremental or conversion cost. To the extent the allowable credit exceeds the person's tax liability for that year the excess may be carried forward for up to five years. Lessees or lessors of qualifying vehicles are also eligible for the credit. The value of the credit is based on the EPA emissions classification of the vehicle as follows:

Type of VehicleTax Year Beginning Prior to January 1, 2010 January 1, 2010-January 1, 2012
Low Emission Vehicle (LEV)50%25%
Ultra Low or Inherently Low Emission Vehicle (ULEV or ILEV) 75%50%
Super Ultra Low or Zero Emission Vehicle (SULEV or ZEV)85%75%

Tax credits for Model Year 2007 HEVs and AFVs are as follows:

Alternative Fuel Infrastructure Tax Credit

For tax years beginning prior to January 1, 2011, the Colorado Department of Revenue offers an income tax credit for the cost of construction, reconstruction, or acquisition of an alternative fuel fueling facility that is directly attributable to the storage, compression, charging, or dispensing of alternative fuels to motor vehicles. The credit value is as follows:

Tax YearTax Credit
2009-201120%
2006-200935%

For an alternative fuel refueling facility that will be generally accessible for use by the public, in addition to the person claiming the credit, the percentages specified above will be multiplied by 1.25. For an alternative fuel refueling facility that dispenses an alternative fuel derived from a renewable energy source, the credit percentages specified above will be multiplied by 1.25 and requires certification that at least 70% of the alternative fuel dispensed annually is derived from a renewable energy source for a period of 10 years. The credit has a maximum value of $400,000 in any consecutive five-year period for each refueling facility. For more information about this credit, see the Colorado Department of Revenue's Alternative Fuel Income Tax Credits Web site.

(Reference Colorado Revised Statutes 39-22-516)

Alternative Fuel Vehicle (AFV) Rebate

A rebate is available from the Colorado Department of Revenue for the purchase of an AFV or for the conversion of a vehicle to operate using an alternative fuel. Vehicles must be owned by the State of Colorado, a political subdivision of the state, or a tax-exempt organization, and be used in connection with the official activities of the entity. HEVs also qualify for this incentive. The rebate is a percentage of the incremental cost if used toward purchasing a new AFV, or is a percentage of the conversion cost if used towards the cost of converting a vehicle to operate using an alternative fuel. For an AFV purchase or conversion that permanently replaces a motor vehicle or power source that is ten or more years old, the percentage specified in the table below is doubled, up to a maximum of 100% of the incremental or conversion cost. Each qualified entity is limited to $350,000 per state fiscal year in total rebates paid. The rebate value is as follows:

Certification Level2009-20112006-2009
Low Emission Vehicle (LEV)0%25%
Ultra Low or Inherently Low Emission Vehicle (ULEV or ILEV)25%50%
Super Ultra Low or Zero Emission Vehicle (SULEV or ZEV)50%75%
