Budget & Taxes (Property Tax)

SB 205 would have revised Montana's voter approval requirements for local property tax levies and bond elections. It would have increased the minimum voter turnout threshold for county bond elections from 30% to 40% (requiring 50%+ of votes cast to approve), and raised the threshold for city/town bond elections from 40% to 50% turnout (also requiring 50%+ of votes cast). These changes directly affected counties and municipalities seeking voter approval for bond measures or mill levies. The bill died in process in May 2025 and did not become law.

SB 204 would have limited most voter-approved property tax levies (mill levies) to a 10-year duration without requiring reapproval by voters. It directly affects local governments - including school districts, cities, and counties - that collect property taxes, requiring them to seek voter reapproval before existing levies expire. Key provisions include setting termination dates for all levies after 10 years (unless exceptions apply) and listing specific exceptions for school levies, community colleges, law enforcement, fire protection, and emergency medical services. The bill aimed to ensure ongoing voter oversight of property tax rates while maintaining stability for essential public services. (Note: The bill died in process on May 23, 2025, and did not become law.)

HB 155 revises property tax laws for Class Four residential and commercial properties. For residential properties, it introduces a graduated tax rate for single-family homes above $1.5 million in market value and sets specific rates for vacant residential lots under $50,000 and certain rental multifamily units over $2 million. For commercial and industrial properties, the bill exempts the first $200,000 of market value from taxation and establishes specific tax rates for the remaining value, with a different rate for golf courses. The bill would have taken effect immediately and applied retroactively to property tax years beginning after December 31, 2024.

SB 351 limits Montana local governments' ability to save ("bank") property tax authority for certain state-mandated tax programs. It specifically amends property tax law to prevent local entities from carrying forward unused mill authority (tax rate allowances) for taxes imposed under statutes 20-9-331, 20-9-333, 20-9-360, and 20-25-439. This change directly affects counties, cities, and school districts that rely on these specific state tax programs, requiring them to use their full annual tax authority each year rather than saving it for future use. The bill’s key provision removes these programs from the existing rule that allows governments to carry forward unused tax authority to future years.

House Bill 411 (HB 411) exempts agricultural property from local property tax levies that are used to fund open space initiatives. This means that owners of land classified as agricultural will no longer be required to pay the portion of their property taxes designated for open space purposes. The bill also allows counties to reduce any open space payments made to agricultural properties that are now exempt from these levies. This change applies retroactively to property tax years beginning on or after January 1, 2025.

SB 540 revises Montana's property tax rules for "class 17 property," specifically targeting dedicated telecommunications infrastructure like fiber optic and coaxial cable. It provides a 5-year tax exemption for new fiber/coaxial cable installations placed in service after July 1, 2021, with the exemption phasing out over 10 years (20% annually). To maintain the exemption, owners must reinvest the tax savings into new Montana cable installations within 2 years without passing costs to consumers. Federal-funded projects (e.g., under the American Rescue Plan) are excluded from the exemption, and owners must keep records for state review. The bill directly affects telecom infrastructure owners and operators in Montana.
