The tax credit is back!!! The H.R. 8 American Taxpayer Relief Act of 2012 was signed in January of 2013 and extends the Residential Energy Tax Credit for qualifying doors and windows purchased from January 1, 2012 through December 31, 2013. As with prior tax credits, it applies to the cost of the product only. The act enables homeowners to receive a tax credit of 10% of the product cost or a maximum of $200 for qualifying windows and 10% of the product costs or a maximum amount of $500 for qualifying doors (cannot exceed $500 total tax credit). Good news!
