There is only one month left to purchase and install items that qualify for the Federal Tax Credits for Consumer Energy Efficiency.
As a reminder, these items need to be both purchased and installed by December 31, 2010.
From energystar.gov:
To qualify for the tax credit, the product needs to be “placed in service” by December 31, 2010. The IRS defines “placed in service” as when the property is ready and available for use. It’s not when you purchase product, but the day installation is complete, and you are able to use your new product.
These tax credits will be claimed on your 2010 taxes (which you must file by April 15, 2011).
