Energy Conservation Installation Credit

Individual taxpayers may claim a credit against their income tax liability for up to 25% of the costs of investment for energy conservation purposes in a building. The maximum credit is $500 per individual (a married couple filing jointly can claim a tax credit of $1,000). The credit must be claimed in the year that the expenditure is made. It is nonrefundable and may not be carried over to future years. For doors, windows, and skylights in new construction, only the amount spent to surpass the applicable state or federal construction and energy standards may be used. Use Montana Department of Revenue Tax Form ENRG-C to take this credit.
