On December 17, 2010, President Obama signed the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010. This law extends the tax credits for energy efficiency into 2011, BUT at lower levels. The levels revert back to those in effect in 2006 and 2007, which were 10% of the cost of the improvement, up to $500, with a $200 max for windows, and several other set maximums. Info per the EPA.

Highlights:

10% up to $500 for insulation, roofs, and doors.

Windows capped at $200, but qualification now ENERGY STAR

Furnace and boilers capped at $150, and all furnaces and boilers must meet 95 AFUE

$50 for advanced main air circulating fan

$300 for air conditioners, water heaters, and biomass stoves

$500 lifetime limit. If you got over $500 in these tax credits from 2006-2010, you are not eligible for anything more.

Note these credits are for energy efficient home improvements and typically cannot be claimed by a company or corporation on commercial property. This information does not include available rebates from your utility provider.
