What is the 45L Tax Credit?

The 45L Tax Credit is a Federal Tax Credit worth $2,000 per dwelling unit that rewards multifamily developers, investors, and homebuilders that develop energy efficient homes and units that are sold or leased after December 31, 2005.

Starting in 2023, the Inflation Reduction Act increases the tax credit amount to as much as $5,000 per dwelling unit for both single-family and multifamily developments. Additionally, the energy efficiency criteria changes to align with Department of Energy programs for Energy Star and Zero Energy Ready Homes. As a result, all residential developments become eligible whereas prior, only low-rise residential developments were eligible.

Eligible Apartment Buildings, Condos, & Single Family Home Developments

A dwelling unit should provide a level of heating and cooling energy consumption that is significantly less than certain energy standards. Based on current construction trends and local building codes, many developments are adopting energy efficient measures that help towards qualification of the 45L tax credits.
