The federal government has changed the tax credit for energy efficient windows and doors enacted as part of the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010. The act was created to stimulate the economy, increase consumer spending, and improve the energy efficiency of the nation's homes.
Signed into law December 17, 2010, the legislation establishes a $200 maximum tax credit for windows and a $500 maximum credit for exterior doors installed between January 1 and December 31, 2011.
There is a new lifetime limit of $500 in credits that a homeowner can claim from January 1, 2006 to December 31, 2011. This $500 limit is NOT on top of the $1,500 limit in 2009-2010. So if a homeowner has already reached or exceeded the $500 limit, they are no longer eligible to claim another credit in 2011. The $500 limit is also not just for windows, doors and skylights, but for any combination of all tax credit qualifying products, such as HVAC equipment, insulation or roofing.
Thompson Creek windows and doors exceed the goverment's minimum standards for energy efficiency and qualify for the tax credit as defined by Energy Star.
