Green Driver State Incentives in Colorado

Numerous state incentives give Colorado drivers the opportunity to save some green by going green. Driver incentives range from those offered by government agencies such as the CO Division of Motor Vehicles to others granted by private entities. To learn more on how you can save money as an eco-friendly driver, read on.

Colorado's incentives and green laws might evolve as the state focuses more and more on the environment. Two additional resources worth consulting are your local Division of Motor Vehicles branch and the Alternative Fuels Data Center.

CO Registration Emissions Testing Exemptions for Fuel Efficient Vehicles

The Colorado Division of Motor Vehicles exempts the following vehicles from emissions testing when it comes time for first-time vehicle registration or car registration renewal. For full details on all CO vehicle emissions exemptions, consult our section on smog and emissions checks.

  • Electric-powered vehicles (EVs).
  • Hybrid electric vehicles (HEVs such as the Toyota Prius and Honda Insite).
  • New vehicles*.

*For the 7 model years, newly manufactured vehicles can skip emission testing and smog checks, unless vehicle ownership changes hands.

If you have questions regarding Colorado emissions exemptions and requirements, call your county motor vehicle office, the Emissions Program office at the Colorado DMV at (303) 205-5603, or visit Air Care Colorado. If you don't qualify for the emissions exemption, locate a nearby gas vehicle emission station through the State or by entering your ZIP code into the Emission Station Locator widget at the bottom of this page.

High Occupancy Vehicle (HOV) Lane Exemption for Hybrid Electric Vehicles (HEVs)

Those who drive hybrid electric vehicles have the green light to use high occupancy vehicle (HOV) and high occupancy toll (HOT) lanes with a single occupant, as permitted by the Colorado Department of Transportation (CDOT). If you have a qualifying and approved vehicle, you must:

  1. Obtain a permit*.
  2. Display an HOV exemption decal.
  3. Display a toll transponder.

To gain eligibility for the HOV/HOT Lane Exemption, you can apply online.

NOTE: CDOT created a waiting list for new applicants as it has already reached its permit quota. For more on this and the hybrid vehicle program, check out CDOT's hybrid FAQs page and the Colorado Revised Statutes 42-4-1012.

Colorado State Tax Incentives and Federal Tax Credits

Colorado offers its green drivers the following state tax and sales tax incentives.

  • Alternative Fuel, Advanced Vehicle, and Idle Reduction Technology Tax Credit.
  • Low Emission Vehicle (LEV) Sales Tax Exemption.

For more on federal tax incentives, see the bottom of this section.

Use the following as a starting place as you dig deeper into Colorado tax incentives. You might also want to consult a tax professional, the CO Department of Revenue or your local IRS Taxpayer Assistance Center for even more details.

Alternative Fuel, Advanced Vehicle, and Idle Reduction Technology Tax Credit

Also known as the Innovative Motor Vehicle Credit, this CO incentive benefits owners of the following:

  • Vehicles that use (or are converted to use) an alternative fuel.
  • Hybrid electric vehicles (HEVs).

  • Vehicles with a replaced power source that use an alternative fuel.

Additionally, the Colorado Colorado Department of Revenue only offers this incentive to qualified individuals who have:

CO tax credits vary depending on the category in which your vehicle falls under and the tax year. For specifics, refer to the category chart listed through the Alternative Fuels Data Center. This chart also lists tax credit info for idle reduction technologies.

Please also note that the Department of Revenue determines the tax credits in one of two ways if you purchased, leased, or converted any of the following during the tax year:

  • Compressed natural gas (CNG) vehicles.
  • Electric vehicles.
  • Plug-in hybrids.

The Colorado Department of Revenue offers a number of Income Tax FYI Publications to help CO residents through the filing process. Two other great resources include House Bill 13-1247, 2013 and Colorado Revised Statutes 39-22-516.5 and 39-22-516.7.

Colorado exempts vehicles, vehicle power sources, and parts from state tax when used for converting a vehicle power source to reduce emissions.

Such a power source includes engine or motor and associated:

  • Wiring.
  • Fueling lines.
  • Engine coolant system.
  • Fuel storage containers.

In order to qualify for this greater limit on a highway that is not part of the interstate system, your AFV must run on alternative fuel or both alternative and conventional fuel. For more on this, refer to Colorado Revised Statutes 25-7-106.8 and 42-4-508.
