§45L Energy-Efficient Home Credit

Section §45L is a little-known tax credit that offers developers a means to offset the costs associated with building energy-efficient single family or multifamily properties. The credit provides a dollar-for-dollar offset against taxes owed or paid in the tax year in which the property is sold or leased.

What is the §45L Tax Credit?

The Internal Revenue Code (IRC) Section §45L is a $2,000 per dwelling unit ($1,000 for manufactured homes) tax credit for each new energy-efficient home which is constructed by an eligible contractor and acquired by a person from the eligible contractor for use as a residence during the tax year. The credit can be taken on amended returns or carried forward up to 20 years.

The IRS requires that a §45L analysis be conducted by a certified third-party using IRS-approved modeling software. A dwelling unit must be certified to provide a level of heating and cooling energy consumption that is at least 50 percent below that of a comparable dwelling unit constructed in accordance with the standards of either the 2003 IECC or 2006 IECC (depending on the year sold or leased). It also must have building envelope component improvements that provide for a level of heating and cooling energy consumption that is at least 10 percent below that of a comparable dwelling unit.
