Replacement Windows in Colorado

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

Colorado runs live IRA Home Energy Rebate programs; whole-home efficiency retrofits (HOMES pathway) can include window replacement when part of a modeled energy-savings project.

• Xcel Energy insulation & air sealing rebates. Xcel Colorado offers home efficiency rebates; window projects qualify indirectly when bundled with a home energy audit and envelope work. (Xcel Energy CO program pages)
• Denver Climate Action Rebates. The City of Denver has run its own climate rebate rounds for home electrification and efficiency upgrades; funding rounds vary by year. (City & County of Denver Climate Action office)

Energy code

Colorado is a home-rule state: Denver enforces the Denver Building Code based on recent IECC editions; requirements can exceed the state baseline.
