Tax Credit Details for Windows and Doors

An exterior window or door (other than a storm window or storm door) is considered an “Eligible Building Envelope Component” when it meets or exceeds the prescriptive criteria established by the IECC for the climate zone in which the window or door is installed.

A taxpayer may treat an exterior window that bears an ENERGY STAR® label and is installed in the region identified on the label as an Eligible Building Envelope Component and may rely on such ENERGY STAR® label, rather than on a manufacturer’s certification statement, in claiming the § 25C credit.

The credit amount established by § 25C of the Internal Revenue Code is:

• 10% of the amount paid or incurred by the taxpayer for qualified energy efficiency improvements installed during the taxable year.
• Up to $200.00 maximum credit for windows for all taxable years (maximum $500.00 credit for all improvements combined).
• Allowed only for amounts paid or incurred to purchase the window or door.
• Not allowed for amounts paid for onsite preparation, assembly, original installation labor, other components or sales tax.
• The purchase must be made during the taxable year for which the credit is claimed.
• Retroactive and with time limits, covering product in service after December 31, 2005 and before January 1, 2008.
