Tax Incentives for Residential Buildings
On this page you'll find information about the tax deductions available for purchasing and installing energy-efficient products and constructing new energy-efficient homes.
The American Recovery and Reinvestment Act of 2009 offers tax credits for residential energy efficiency measures and renewable energy systems. Many of these credits were originally introduced in the Energy Policy Act of 2005 (EPACT) and amended in the Emergency Economic Stabilization Act of 2008 (P.L. 110-343).
Energy Efficiency Tax Credits for Existing Homes
Homeowners are eligible for a tax credit of 30% of the cost for improvements to windows, roofing, insulation, and heating and cooling equipment. These improvements must be placed in service from January 1, 2009 through December 31, 2010 and there is a limit of $1,500 for all products. Improvements made in 2008 are not eligible for a tax credit. See the ENERGY STAR® Web site for a detailed listing of eligible improvements.
Renewable Energy Tax Credits for Existing or New Homes
Homeowners can receive a tax credit of 30% of the cost of the following renewable energy technologies with no upper limit: geothermal heat pumps, photovoltaic systems, solar water heaters, and small wind energy systems. Fuel cells are also eligible for a tax credit with a cap. These must be placed in service by December 31, 2016. See the ENERGY STAR Web site for detailed information.
Tax Credits for Home Builders
Builders will receive a credit for energy-efficient homes that are substantially completed after August 8, 2005 and purchased for use as a residence from January 1, 2006 through December 31, 2009. Homes must achieve reductions in heating and cooling energy consumption relative to the 2004 International Energy Conservation Code (IECC) and supplements.
Home builders can receive a credit of $2,000 for homes meeting a 50% energy savings with at least 1/5 of the savings coming from building envelope improvements. This credit also applies to contractors of manufactured homes.
Producers of new manufactured homes can receive a $1,000 tax credit for meeting a 30% energy savings with at least 1/3 of the savings coming from building envelope improvements. As an alternative, manufactured homes may also meet the ENERGY STAR program requirements to qualify for this credit.
See the ENERGY STAR Web site for further information for builders.
