Incentives for Change

The Consolidated Appropriations Act, 2021, signed into law on December 27, 2020, extends the federal tax credit for geothermal heat pump installations through 2023. Residential credits will remain at 26% of the total installation cost through 2022, stepping down to 22% in 2023. The credits will expire on January 1, 2024.

Credits for commercial installations will remain at the current level of 10% through 2023. The new law also makes permanent the Section 179D Energy Efficient Commercial Buildings Deduction of the federal tax code, affording substantial financial benefit for commercial building owners.

Placed in Service Requirement

The IRS defines “placed in service” as when the property is ready and available for use. It’s not when you purchase the product, but the day the installation is complete, and you are able to use your new product.
