About 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 for their share of investments in the same building. For example, a married couple who jointly own their home may each claim a credit up to $500 or $1,000 for the couple if the investments were paid with joint funds or each spouse used their own funds.
