Storm windows can be very effective at cutting down on energy loss and drafts at windows. If you’re thinking about buying new storm windows, be aware that U.S. taxpayers can take advantage of 2009 federal tax credits to help offset the cost.

What is covered? The program covers storm windows that, when used in combination with the exterior window, meet IECC requirements for the climate zone in which they are installed.

Amount of federal tax credit: 10% of the material cost, up to $200. Installation costs are not included.

Notes: The storm windows must be placed into service between January 1, 2009, and December 31, 2009. A Manufacturer’s Certification (a signed statement from the manufacturer certifying that the product qualifies for the tax credit), is often available from the manufacturer’s Web site. This should be kept in your tax records along with your receipt. Note that this statement will list classes of exterior window (single pane, clear glass, double pane, low-E coating, and so forth) that a product may be combined with to be eligible in specific climate zones. When filing, submit IRS Tax Form 5695 (version 2009), which may not be available on the IRS site until late 2009 or early 2010.
