Energy Related Tax Relief

The following information is provided to assist you in understanding the Energy Conservation Installation Credit as well as other energy credits and incentives. The information is available in brochure format.

Energy Conservation Installation Credit

The Department of Revenue encourages citizens to weatherize their homes and take advantage of the Energy Conservation Installation Credit when individual income tax returns are filed.

The credit is applied against a taxpayer's income tax liability.  Montana resident individuals can claim the credit for energy conservation investments made to a home or other building.  The credit is equal to 25% of expenses, up to a maximum credit of $500.  Two or more people may each qualify for the credit, as long as the building in which the investment is made is owned by all of the people claiming the credit.  For example, a married couple who jointly own their home may each claim a credit up to $500 each or $1,000 for the couple.

The following investments qualify for the energy conservation credit:

  • Insulation of floors, walls, ceilings and roofs in existing buildings
  • Insulation in the floors, walls, ceilings and roofs of a new building to the extent that it exceeds the current International Energy Conservation Code with Montana amendments as adopted by the Montana Department of Labor and Industry
  • Insulation of heating and air conditioning pipes, insulation and sealing of heating, ventilation and air-conditioning (HVAC) ducts, and insulation of hot-water heaters and tanks
  • Installing windows that result in a reduction of energy consumption
  • Installing storm doors and insulated exterior doors
  • Caulking and weather stripping of an existing structure
  • Installing devices which limit the flow of hot water from shower heads and lavatories
  • Installing heat recovery ventilators (HRV)
  • Installing glass fireplace doors on existing fireplaces
  • Installing exhaust fans to reduce air conditioning requirements
  • Replacing incandescent light fixtures of a more efficient type, such as those with electronic ballast and compact or linear fluorescent lamps and LED lights
  • Installing lighting controls with cutoff switches to permit the selective use of lights
  • Installing programmable thermostats
  • Installation of new domestic water heaters, heating or cooling systems, so long as the replacement has an efficiency rating higher than the prior system

Examples of improvements that do NOT qualify

If you qualify for this credit, you will need to complete Form ENRG-C and attach it when you file your individual income tax return. Qualifying expenditures purchased and installed in 2008 can be reported as a credit on your 2008 individual income tax return. Please include Form ENRG-C.
