Part of the Federal Energy Policy Act of 2005, 45L granted builders tax credits for new, single- and multi-family energy-efficient homes.

The original credit expired on December 31, 2021. However, the Inflation Reduction Act (IRA) of 2022 extends and enhances the 45L tax credit for builders. The enhanced 45L provision, known as the New Energy Efficient Homes Tax Credit, increases the energy savings requirements to newer standards, but offers a larger tax credit incentive.

As an air seal spray foam easily checks all the boxes required to achieve Energy Star 3.2. Save time and operational frustration knowing that your homes will pass.

When does this program begin?

New requirements for the 45L tax credit became effective on January 1, 2023. The enhancements provide a $2,500 tax credit for homes built to Energy Star 3.2 and a $5,000 tax credit for homes built to the DOE Zero Energy Ready Homes program (DOE ZERH v2)

When does this program expire?

The 45L tax credit is funded through December 31, 2032.

How do I file for the tax credit?

Via year-end tax filing.

What documents do I need to file?
