Provide income tax benefit to support emergency response volunteers

This bill creates a Montana income tax deduction for volunteer firefighters and volunteer emergency care providers who serve as full-service volunteers. The key provision allows these individuals to subtract their volunteer service income from their Montana taxable income, with the deduction amount adjusted annually based on inflation. The legislation amends existing state tax code to establish this new benefit and includes a delayed effective date for implementation. This change directly affects volunteer emergency responders in Montana who currently pay taxes on income earned while serving without compensation.
