IRS Clarifies What Qualifies for Home Owner Energy Tax Credit

The Internal Revenue Service has published new guidance on Internal Revenue Code Section 25C, which allows up to a $1,500 tax credit for home owners who install energy-efficient windows, insulation and other qualifying products. The tax credit is equal to 30 percent of the qualified energy efficiency expenses paid by the home owner, but it is limited to $1,500 for improvements made during 2009 and 2010.


Notice 2009-53 explains the requirements for home owners to claim the 25C credit and provides detailed technical information regarding what improvements can qualify. Home owners can claim the credit only for improvements made to an existing home. However, NAHB has learned from the IRS that tax credit-qualified improvements installed in an addition to an existing home also qualify for the 25C program.

Among the highlights:

  • Tax credit eligible products must be reasonably expected to remain in use for at least five years. One method taxpayers can rely on to satisfy this requirement is to purchase products from a manufacturer who offers a warranty lasting at least two years at no additional cost.
  • Not all Energy Star-rated products that are installed qualify for the tax credit. The Energy Star Web site includes a detailed listing of products that qualify for the section 25C program.
  • The credit excludes installation costs for building envelope components — such as insulation and windows. In order for the home owner to claim the credit, the remodeler must provide an itemized breakout of the cost of these installed products, minus any labor or installation charges.

Also of importance, Notice 2009-53 provides the set of transition rules for qualified products installed before June 1, 2009. For these installations, taxpayers can claim for tax credit purposes the installation of property that meets less stringent energy efficiency requirements.

In particular, taxpayers can claim the credit for installation of windows and skylights that meet Energy Star requirements, requirements listed under prior IRS Notice 2006-53 or manufacturers’ certifications for 25C made under IRS Notice 2006-53. For installations on or after June 1, the requirements listed in Notice 2009-53 and described above are binding.


NAHB Teleconference on Claiming Energy-Efficiency Tax Credits

Newly expanded federal tax credits for energy efficiency are providing consumers with added incentives for upgrading their homes. Homeowners now can claim up to $1,500 in tax credits for remodeling their principal residence to reduce energy consumption through the enhanced Existing Home Retrofit (25C) tax credit. During a media teleconference next week, NAHB’s Director of tax issues discussed how to take advantage of the credit, while three professional remodelers from around the country provided examples of the types of projects that may qualify, such as adding insulation, replacing doors and windows, and updating heating and cooling systems. The panelists also provided guidance on selecting a qualified remodeler and certifying home remodelers under the National Green Building Standard, which is the only national standard to certify green home remodeling and renovation projects.
