Tax credits and rebates
Federal Tax Credits
The American Recovery and Reinvestment Act of 2009, H.R.1 (the Stimulus Bill of 2009), contains long-term tax incentives to encourage the installation of geothermal heat pumps in residences. It offers a one-time tax credit of 30% of the total investment for geothermal heat pump installations.
It should be understood that a tax credit is generally more valuable than a tax deduction of the same magnitude because a tax credit reduces the tax obligation directly, while a deduction only reduces taxable income.
A tax credit of 10% of the total investment is also available without a maximum credit limit for commercial installations.
Under the IRS rules, manufacturers need to certify that specific measures are eligible. Taxpayers should obtain a copy of this certificate (see below) when buying these products from the manufacturer, contractor or retailer. Certifications need not be submitted to the IRS, but should be kept on file in case the IRS has questions.

Under the federal Modified Accelerated Cost-Recovery System (MACRS), businesses may recover investments in certain property through depreciation deductions, possibly reducing the cost of a geothermal system by 40%.
Tax Incentives Assistance Project (TIAP)
TIAP is sponsored by a coalition of public interest nonprofit groups, government agencies, and other organizations in the energy efficiency field, and is designed to give consumers and businesses information they need to make use of the federal income tax incentives for energy efficient products and technologies passed by Congress as part of the Energy Policy Act of 2005 and subsequently amended several times.
