In December 2020, the tax credit for geothermal heat pump installations was extended through 2023. Geothermal equipment that uses the stored solar energy from the ground for heating and cooling and that meets ENERGY STAR requirements at the time of installation is eligible for the tax credit. The credit has no limit and there's no limitation on the number of times the credit can be claimed.
US Tax Credits Through 2023
The energy tax credit can be combined with solar and wind credits as well as energy efficiency upgrade credits. A 26% federal tax credit for residential ground source heat pump installations has been extended through December 31, 2022. The incentive will be lowered to 22% for systems that are installed in 2023, so act quickly to save the most on your installation.
Even without incentives, installing a geo system just makes sense. It's the only type of system that will pay you back. Most homeowners save more on monthly bills than they pay for the system when installation costs are financed. Any added investment over traditional equipment is usually recovered in just a few years, and many homeowners see a return on investment of 10-20% over the life of the system.
