Revise tax increment financing districts to exclude debt service and certain school levies

This bill updates Montana's tax increment financing laws to exclude certain school levies and debt service payments when calculating tax increments for newly created economic development districts. It directly affects local governments, school districts, and property owners within areas designated for targeted economic development or urban renewal. The key provision specifies that for districts created on or after the effective date, tax increment calculations must not include mill levies for school debt service, certain school funding measures, and university system taxes. This change aims to clarify how property tax revenue is allocated by ensuring specific school-related taxes are not counted toward the incremental growth used to fund development projects.
