Did you make energy efficiency improvements to your home in 2011-2013? Receive a federal tax credit for energy efficiency improvements in the building envelope of existing homes and for the purchase of high-efficiency heating, cooling and water-heating equipment.
Efficiency improvements or equipment must serve a dwelling in the United States that is owned and used by the taxpayer as a primary residence.The maximum tax credit for all improvements made in 2011, 2012, and 2013 is $500. The cap includes tax credits for any improvements made in any previous year. If a taxpayer claimed $500 or more of these tax credits in any previous year, any purchases made in 2011, 2012, or 2013 will be ineligible for a tax credit.
