Federal Tax Credits for Energy Efficiency includes:

**Please note, not all ENERGY STAR qualified homes and products qualify for a tax credit. These tax credits are available for a number of products at the highest efficiency levels, which typically cost much more than standard products. If, for whatever reason, you decide not to purchase a product covered by the tax credit, you may still consider purchasing an ENERGY STAR product. ENERGY STAR distinguishes energy efficient products which, although they may cost more to purchase than standard models, will pay you back in lower energy bills within a reasonable amount of time, without a tax credit.

Tax Credits for Consumers:

Efficient Cars

Starting January 1, 2009, there is a new tax credit for Plug-in hybrid electric vehicles, starting at $2,500 and capped at $7,500 for cars and trucks (the credit is based on the capacity of the battery system). The first 250,000 vehicles sold get the full tax credit (then it phases out like the hybrid vehicle tax credits).

Tax credits are available to buyers of hybrid gasoline-electric, diesel, battery-electric, alternative fuel, and fuel cell vehicles. The tax credit amount is based on a formula determined by vehicle weight, technology, and fuel economy compared to base year models. These credits are available for vehicles placed in service starting January 1, 2006. For hybrid and diesel vehicles made by each manufacturer, the credit will be phased out over 15 months starting after that manufacturer has sold 60,000 eligible vehicles. For vehicles made by manufacturers that have not reached the end of the phase-out, the credits will end for vehicles placed in service after December 31, 2010. See the IRS Website for updated information

Tax Credits for Home Builders:

Eligible contractors need to fill out IRS Form 8908 PDF to get the tax credit. The IRS has provided the following guidance regarding the tax credits for constructing energy efficient new homes available under the Energy Policy Act of 2005:

  • IRS Notice 2006–27 PDF provides guidance for the credit for building energy efficient homes other than manufactured homes.
  • IRS Notice 2006–28 PDF provides guidance for the credit for building energy efficient manufactured homes.

Home builders are eligible for a $2,000 tax credit for a new energy efficient home that achieves 50% energy savings for heating and cooling over the 2004 International Energy Conservation Code (IECC) and supplements. At least 1/5 of the energy savings must come from building envelope improvements. This credit also applies to contractors of manufactured homes conforming to Federal Manufactured Home Construction and Safety Standards.

There is also a $1,000 tax credit to the producer of a new manufactured home achieving 30% energy savings for heating and cooling over the 2004 IECC and supplements (at least 1/3 of the savings must come from building envelope improvements), or a manufactured home meeting the requirements established by EPA under the ENERGY STAR program.

Please note that, with the exception of the tax credit for an ENERGY STAR qualified manufactured home, these tax credits are not directly linked to ENERGY STAR. Therefore, a builder of an ENERGY STAR qualified home may be eligible for a tax credit but it is not guaranteed.

These tax credits apply to new homes located in the United States whose construction is substantially completed after August 8, 2005 and that are acquired from the eligible contractor for use as a residence from January 1, 2006 through December 31, 2009.

Tax Deductions for Commercial Buildings:

A tax deduction of up to $1.80 per square foot is available to owners or designers of new or existing commercial buildings that save at least 50% of the heating and cooling energy of a building that meets ASHRAE Standard 90.1-2001. Partial deductions of up to $.60 per square foot can be taken for measures affecting any one of three building systems: the building envelope, lighting, or heating and cooling systems. These tax deductions are available for systems “placed in service” from January 1, 2006 through December 31, 2013.

Take the ENERGY STAR Challenge to find the best opportunities for energy savings, set goals for improvement, and achieve superior energy efficiency.

Tax Credit Legislation:

The Energy Policy Act of 2005 first established the energy efficiency tax credits that were effective in 2006 & 2007. The majority of these tax credits were for 10% of the cost, up to $500. On October 3, 2008 former President Bush signed the Emergency Economic Stabilization Act of 2008 (also known as the “Bailout Bill”) to put many of the tax credits back in place for 2009, and increased the credit to 30%, up to $1,500. On February 17, 2009 President Obama signed into law the American Recovery and Reinvestment Act of 2009 (also known as the “Stimulus Bill”) which among other changes extended the tax credits to 2010.
