Sales and Use Tax Exemption for Renewable Energy Equipment
You are here
Colorado exempts from the state's sales and use tax all sales, storage, and use of components used in the production of alternating current electricity from a renewable energy source for fiscal years beginning on or after July 1, 2006. The exemption for systems which produce electricity from a renewable resource includes, but is not limited to, photovoltaic (PV) systems, solar thermal-electric systems, small wind systems, biomass systems, or geothermal systems.
Effective July 1, 2009, through July 1, 2017, all sales, storage, and use of components used in solar thermal systems are exempt from the state's sales and use tax. Effective May 5, 2014, through July 1, 2019, all sales, storage, and use of components used in biogas production systems are exempt from the state's sales and use tax (see H.B. 1159).
System Components Exempt from Taxation
Eligible components include, but are not limited to, wind turbine generators, rotors and blades, solar modules, trackers, supporting structures or racks, inverters, towers and foundations, plus balance of system components such as wiring, control systems, switchgears, and generator step-up transformers. Also exempt are concentrating solar power components that include, but are not limited to: mirrors, plumbing, and heat exchangers.
Ineligible components include any components beyond the step-up transformers located at the production site, labor, energy storage devices, or remote monitoring systems.
Local Option -- Sales and Use Tax Exemption
The exemption only applies to state sales and use taxes – not to sales and use taxes assessed by incorporated towns, cities, and counties. However, Colorado has granted local jurisdictions the authority to exempt renewable energy equipment from sales and use taxes if a local government chooses to do so.
