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.
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.
In addition to the federal tax credit, some state, local, and utility incentives may be available in your area for even more savings on installing a geothermal heat pump. Check out the Database of State Incentives for Renewables & Efficiency (DSIRE) website to find policies and incentives in your area.
