ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. It is designed to assist consumers in the recognition of energy efficient products and promote the environmental and economic benefits of these products through the ENERGY STAR label and other program activities.
APPLICABLE FOR TAX YEAR 2011
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 onlyfor 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. (Between Jan. 1 and Dec. 31, 2010)
