Revising property appraisal to use an average value

This bill changes how Montana property taxes are calculated by requiring appraisers to use a 10-year average of market values (excluding the highest and lowest years) instead of a single-year value. It directly affects all property taxpayers, including homeowners and businesses, as it alters the baseline for determining taxable property value. The key provision amends Montana law to establish this averaging method for most taxable property, aiming to create more stable and predictable annual tax assessments. This change applies broadly, with specific exceptions for agricultural equipment, condominiums, and commercial properties as outlined in the bill.
