HB 451 Montana House · 2025 Regular Session

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

HB 451 revises how tax increment financing (TIF) is calculated for newly established targeted economic development districts and urban renewal areas. For districts created after the bill's effective date, it excludes several specific mill levies from the tax increment calculation. These exclusions include certain university system mills, a portion of elementary, high school, and state equalization mills, new voter-approved levies, and mills for general obligation bond debt service. This means that a larger share of the new property tax revenue generated in these areas would directly go to the affected taxing jurisdictions, rather than into the TIF fund.
