Some of the most popular federal income tax credits for home energy efficiency improvements have been renewed for 2011. While the new credits are smaller than the 2010 credits, they still provide a great incentive for homeowners to make needed upgrades.
The 2011 tax credits return 10% of the cost of certain heating, cooling, and building envelope improvements, up to $ 500, with these exceptions:
Window credits are limited to $200 and now include Energy Star windows;
Oil and gas furnace and boilers that are 95% efficient receive credits of up to $150, plus $50 for efficient furnace fans; and
Water heater and wood heating system credits are limited to $300.
