Energy Efficient Home Improvement Credit

Principal Residence Owners: Upgrades must be to an existing home & your principal residence. New construction and rentals do not apply.

A principal residence is the home where you live most of the time. The home must be in the United States. It can include a house, houseboat, mobile home, cooperative apartment, condominium, and a manufactured home.

Annual Limits on Energy Efficient Home Improvement Tax Credits
In addition to limits on the amount of credit you can claim for any particular equipment installation or home improvement, there are annual aggregate limits. The overall total limit for an efficiency tax credit in one year is $3,200. This breaks down to a total limit of $1,200 for any combination of home envelope improvements (windows/doors/skylights, insulation, electrical) plus furnaces, boilers and central air conditioners. Any combination of heat pumps, heat pump water heaters and biomass stoves/boilers are subject to an annual total limit of $2,000. (Note: ENERGY STAR certified geothermal heat pumps are eligible for a separate tax credit and not counted against these limits.)

Some utilities and local governments offer rebates, incentives, and other financial assistance for home efficiency improvements. Check with your utility or use the Energy Star or Switch is On websites to find local program offerings. Some may have income qualifications.
