Federal Tax Credits
Builder tax credit for new homes
A $2,000 tax credit is available for builders of energy-efficient homes. To qualify, the home must demonstrate a 50 percent reduction in heating and cooling energy over the 2003 International Energy Conservation Code (IECC), as determined by a qualified energy rater. This credit was recently extended to homes built before December 31, 2011.
Homeowner tax credits for existing homes
Building envelope improvements to existing homes, such as installing SIP insulated nailbase, are eligible for a 10% tax credit, with a cap of $500 per home. This credit was also recently extended through December 31, 2011.
