The American Recovery and Reinvestment Act adopted in October 2008 allows for a 30% tax credit for costs associated with ENERGY STAR qualified geothermal heat pumps, as noted in section 25D of the Internal Revenue Code. The 30% credit applies to geothermal equipment placed in service through 2019. Tax credits will still be available at a reduced rate until 2022.

What exactly is the difference between a tax deduction and a tax credit?
A tax deduction reduces the amount of your income that is considered taxable by the IRS. A tax credit is taken after the determination of the amount of taxes that you have to pay. Tax credits are dollar for dollar reductions in the amount of taxes you owe, and are the same for everyone, regardless of income level.
What if my geothermal tax credit amount exceeds my tax liability?
You will not lose any of the remaining balance. The residual amount will be carried forward into future years and applied to that tax liability.
Can I claim the tax credit if I install a qualified geothermal heat pump in my existing home?
Yes, the tax credit applies to existing residential installations as well as new construction.
Is there any geothermal equipment not covered under this tax credit?
The tax credit only applies to new "qualified geothermal heat pump property." Geothermal equipment that does not meet ENERGY STAR requirements effective at the time the equipment is installed is not eligible. Also excluded is equipment used exclusively to heat swimming pools or hot tubs or previously used geothermal equipment.
Am I eligible for the tax credit if geothermal equipment is installed in my condo?
Possibly. You may be able to claim the tax credit on your share of the condominium association's geothermal spending. The tax code has specific restrictions, so please consult your tax professional and homeowner's association for further information.
Can I get this tax credit if I install a geothermal system at my business location?
There is a separate 10% tax credit available for businesses installing geothermal equipment. If you have a business operating out of your home, consult your tax professional for proper allocation of the residential tax credit.
