What Is the Montana Form WMRE?
Montana Form WMRE is a tax exemption form for military retirees and survivors of military service members that allows them to exempt a portion of their military retirement income or survivor benefits from Montana state income tax. The exemption applies to those who became residents of Montana after June 30, 2023, or who were residents of Montana before July 1, 2023, and began receiving military retirement income or survivor benefits while a Montana resident. This exemption can only be claimed for five consecutive years, beginning with the 2024 tax year, and is available until 2033.
The exemption amount is determined by calculating the lesser of 50% of military retirement income or survivor benefits, or the total income from various Montana sources such as wages, business income, farming income, etc. The amount can be deducted from your taxable income, reducing your overall tax burden in Montana.
