Eliminate state income taxes on veterans retirement

This bill would exempt military pensions, retirement benefits, and survivor benefits from Montana state income tax. It directly affects veterans and their families who receive these benefits and currently pay state income tax on them. The legislation amends existing state tax code sections to establish this exemption and repeals a previous 2023 provision that may have affected this area. The bill also includes updated definitions for various tax terms to ensure clarity in how the exemption is applied.
