Colorado Property Tax Exemption for Renewable Energy Systems

Colorado enacted legislation in April 2007 (SB 145) to authorize counties and municipalities to offer property or sales tax rebates or credits to residential and commercial property owners who install renewable energy systems on their property. HB 1126 of May 2009 added solar thermal (non-electric) systems to the list of renewable energy equipment eligible for the property tax exemption.

The program would be administered at the local level by individual cities and counties. Individuals should contact the cities or counties where their property is located to see if a tax rebate or credit will be established in their community.
