Provide for class of property for manufacturing for property tax purposes

This bill creates a new property tax class (class nineteen) specifically for manufacturing properties in Montana. It defines qualifying manufacturing property as land and improvements used for transforming materials into new products or assembling components (excluding construction), and sets a lower tax rate of 1.47% on this class - significantly below standard rates. The law applies to property tax years starting January 1, 2026, directly affecting manufacturers whose property meets the defined criteria. It clarifies tax treatment for parcels with mixed uses by basing classification on the largest share of improvements.
