On October 3, 2008, President George W. Bush signed into law the Emergency Stabilization Act followed by President Barack Obama signing into law the American Recovery and Reinvestment Act of 2009 (ARRA) on February 17, 2009. The combined effect of these two laws provides the:
Investment Tax Credit (ITC)
Allowing homeowner's to receive the Investment Tax Credit (ITC) on both the purchase and installation of qualifying products in renewable technologies such as solar electric property, residential solar water heating, qualified small wind energy and qualified geothermal heat pump energy, among others.
For skylights & sun tunnels that ARE NOT equipped with solar may qualify for the:
Energy Efficiency Improvement Credit
Windows, doors and skylights that earn the ENERGY STAR save energy, improve comfort and help protect the environment. You do not have to replace all the windows/doors/skylights in your home to qualify. And it doesn't need to be a replacement either - installing a new window where there wasn't one previously (like in an addition) qualifies.
Tax Credit Amount: 10% of the cost, up to $500, but windows are capped at $200. (Tax credit does not include installation costs.)
