As part of the Federal Stimulus package, homeowners can now receive up to a 30% tax credit for making their home more energy efficient (http://www.djc.com/news/bu/12004940.html?cgi=yes).

What is eligible? Built goods such as energy efficient windows, additional insulation and heating/cooling equipment fall within the categories. Items such as that new washer and dryer or refrigerator you’ve been wanting are not eligible.
Your contractor will need to separate out the cost of materials/supplies vs. the labor, because they are viewed differently. But the tax credit will be a dollar for dollar reduction on what you owe the federal government for next year’s taxes.
Of course the real benefit to all this is a more energy-efficient home that will save you money and help to save the earth. The government is just sweetening the pot for you to do this now, rather than later.
So call your contractor (our number is 425.453.8388) and schedule an appointment to talk about your home improvements.
