Energy Conservation...  In Your Home

Tax Credit and Incentives

Energy efficiency improvements can reduce your Montana tax bill as well as your monthly energy bills.  Montana homeowners are eligible for a tax credit for a portion of the costs of installing additional insulation, caulking materials or other measures that reduce energy use and lower your utility bills. The amount of the tax credit is 25 percent of the investments you make to improve the energy efficiency of your home. The maximum amount of the credit for each tax year is $500 per taxpayer. 

The Montana Department of Revenue has determined that all of the following conservation investments are eligible for the credit:

  • For existing homes: insulating floors, walls and ceilings
  • High efficiency heating systems (ENERGY STAR rated)
  • Sealing and insulating duct work or piping in non-heated areas
  • Hot water tank insulation blankets
  • Storm windows
  • Programmable or set-back thermostats
  • Replacement of incandescent light fixtures with high efficiency lighting  fixtures. This applies only to permanent fixtures, not to efficient light bulbs such as compact fluorescents installed in existing fixtures.
  • Energy efficient windows

This is only a partial list of items that may qualify.

The Energy Conservation Tax credit can be used both for new construction and remodeling projects. However, for new construction and remodeling projects the tax credit is allowed ONLY for the portion of the cost and materials that is above established standards of construction.

You apply for the tax credit by completing tax form "ENRG-C" for individual income taxpayers. The energy conservation credit is allowed ONLY for the year the energy conservation improvements are placed in service.
