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:
- Heat recovery ventilators (HRV) **(See note below)
- Glass fireplace doors on existing conventional fireplaces
- Exhaust fans to reduce air conditioning requirements
- Replacement of incandescent light fixtures with fixtures of a more efficient type such as those with electronic ballast and compact or linear fluorescent lamps and LED lights
- Lighting controls with cutoff switches to permit the selective use of lights
- Programmable thermostats
- Installation of new domestic water heaters, heating or cooling systems, so long as the new system uses energy more efficiently than the prior system **(See note below)

- 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
- Windows that result in a reduction of energy consumption **(See note below)
- Storm doors and insulated exterior doors **(See note below)
- Caulking and weather stripping of an existing structure (except when it is a standard component in the construction or maintenance of the structure such as the chinking and caulking in a log home)
- Devices which limit the flow of hot water from shower heads and lavatories
**Please note - If any of the indicated items were installed after June 30, 2010 either in an existing building or while constructing a new building, the following applicable specification must be met or exceeded in order for the investment to qualify for the credit:
