Geothermal Tax Credits in the US

Residential Geothermal Tax Incentives

Planning an energy efficiency project with solar, wind, or geothermal? Through 2016 federal energy tax credits for all three are unlimited, with a 30% return on taxes.


Through December 31, 2016 taxpayers receive an unlimited 30% tax credit on qualifying solar, wind, and geothermal residential energy improvements. The systems must meet or exceed EnergyStar requirements and be located in the US. Qualifying homes include:

Primary residence
Second homes
Existing homes
New construction

Rentals do not qualify for this break. The inclusion of second homes is a departure from previous federal energy tax credits and dramatically expands the potential reach of this program.

Consult your local tax professional for advice on taking advantage of the tax credit, as this announcement is not intended as a recommendation or endorsement of any financial strategy.
