Geothermal tax credit
As part of the economic rescue bill (H.R. 1424) passed in October 2008, a residential system installed and placed in service between January 1, 2009 and December 31, 2016 was previously eligible for a tax credit equal to 30% of the installed cost of the system up to a cap of $2,000 for a single residence. The Stimulus Bill signed in 2009 by President Obama improves that tax credit and removes any cap from the incentive. A homeowner is no longer limited, and may collect the full 30% of the installed system cost as a tax credit for systems that are installed after January 1, 2009. In addition, if a homeowner is not able to use the entire tax credit in the year the system is installed, they may carry the unused portion of the credit into the next year.
A new Energy Star specification for geothermal heat pumps went into effect on December 1, 2009. The qualifications for Energy Star were expanded and Water-to-Water units were added.
A qualified system must meet the following requirements:
- Installed after January 1, 2009 and before December 31, 2016.
- According to the Internal Revenue Service (IRS) guidance, the Federal tax credit is tied to the Energy Star specification that is in effect at the date of purchase.
- EnergyStar encourages the use of a heat recovery module but this is not required under the guidlines effective December 1, 2009.
- Installed in a residence (not limited to primary residence).
- For purposes of Energy Star qualification, geothermal heat pumps include the following: open loop, closed loop, and DGX and are powered by a single phase current.
- The taxpayer has to file IRS Form 5695 to receive the credit.
The state of Kentucky also offers a personal tax credit of $250 for geothermal installations through 12/31/2015.
