42.22.1311    INDUSTRIAL MACHINERY AND EQUIPMENT TREND FACTORS

(1) Prior to January 1 of each year, the department calculates trend factors to value industrial machinery and equipment for ad valorem tax purposes pursuant to ARM 42.22.1306. The department uses annual cost indexes from the Marshall & Swift Guide described in ARM 42.21.155. The current index is divided by the annual index for each year to arrive at a trending factor. Each major industry has its own trend factor table containing industry descriptions with the applicable trend table number and life expectancy. Where no index exists in the Marshall & Swift Guide for an industry, that industry is grouped with other industries using similar equipment. Industrial machinery and equipment remain taxable at the level of the final year of life expectancy until its disposal.

(2) The department shall post its trend factor tables for industrial machinery and equipment for the upcoming tax year on the department's website located at http://www.mtrevenue.gov. The department adopts and incorporates by reference its 2024 Personal Property Depreciation Schedules and Trend Tables publication, effective January 1, 2024. The Depreciation Schedules and Trend Tables publication contains the detailed schedules and tables the department uses for valuing personal property and industrial machinery and equipment.

(3) Mining machinery and equipment is engaged in the extraction, excavation, burrowing, or otherwise freeing raw material from the earth. Mobile mining equipment moves under its own power or on its own wheels and chassis, including any attachments used with or attached to such equipment, but does not include equipment that requires a foundation for the performance of the function for which it was designed and built. Mobile mining equipment used for extraction is valued by using the procedures established for heavy equipment found in ARM 42.21.154 and 42.21.155.
