SB 102 limits annual revenue growth for specific education levies in Montana. It caps the increase in property tax revenue from state school equalization levies and vocational-technical education levies at no more than 3% above the previous year's total. The bill also prevents school districts from carrying forward unused mill authority (property tax rate authority) for these specific levies. This directly affects school districts that rely on these levies for funding, ensuring their revenue growth cannot exceed 3% annually without voter approval. The policy change applies to the calculation method for these levies as outlined in Montana law.
SB 558 proposed replacing school property taxes with a statewide sales tax to fund public schools. It would create a new general sales tax, redirect all revenue to a dedicated school funding account, and repeal existing statewide property tax levies for schools. The bill would directly affect school districts and property taxpayers by shifting funding responsibility from local property taxes to a statewide sales tax, with certain exemptions (like agricultural sales) specified. However, the bill was tabled in committee and died in the legislative process in 2025, so it never became law.
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 32 revises Montana's property tax structure by adjusting tax rates for multiple property classes. It lowers the tax rate for mining property (Class 2) from 3% to 1.65% of gross proceeds, sets agricultural land (Class 3) at 1.65% of productive value, and modifies residential/commercial rates (Class 4), including a reduced 1% rate for owner-occupied homes and a 1.4x multiplier for properties over $1.5 million. The bill also adds an inflation adjustment for local government tax levies and clarifies definitions for properties like nonproductive mining claims and owner-occupied residences. These changes directly affect property owners across Montana, particularly in agriculture, mining, and residential real estate.
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.
SB 2 clarifies how local governments calculate property tax levies when a tax increment financing (TIF) district ends. It specifies that the value previously held in the TIF district (the "increment") must be treated as "newly taxable property" for tax calculations in the year of termination or the following year. This directly affects Montana local governments, as it ensures they can include this value when determining property tax revenues under existing levy formulas, without treating it as new construction or annexation. The bill amends Montana Code Annotated sections 15-10-420 and 20-9-336 to define these rules clearly.
SB 108 requires Montana local governments (counties, cities, school districts) to get voter approval before raising property taxes or issuing bonds to pay court judgments, settlements, or tax protest refunds that exceed existing tax limits. Specifically, if a government needs to collect more tax revenue than permitted under current law (2-9-108) to cover these costs, voters must approve the levy or bond issuance. The bill amends multiple statutes to enforce this voter approval step for such "excess" tax increases. It does not change how governments pay routine expenses but adds a new voting requirement for specific, larger financial obligations tied to legal disputes. This affects local budgets when resolving court cases or tax disputes that require funding beyond standard tax allowances.
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.
SB 307 redirects Montana's marijuana tax revenue to fund prevention programs, law enforcement, and local grants. It creates a new marijuana prevention account to support primary substance misuse prevention and youth suicide prevention programs through community-based services. The bill establishes a marijuana tax revenue accountability council to advise on fund allocation and requires annual impact reports on public health metrics like youth access and hospitalizations. These funds, previously distributed differently, will now specifically target prevention services and law enforcement operations under new reporting rules.
SB 215 revises Montana's public school funding system by redefining the "basic system of free quality public schools" to explicitly include open enrollment, student achievement tracking, and transparency in spending. It requires the legislature to consider specific factors when setting funding - such as student needs (including special education, English learners, and American Indian students), school density, and teacher retention - while mandating that funding follows students across district lines during open enrollment. The bill also directs the funding formula to use current-year enrollment data, include annual cost-of-living adjustments, and clearly show how funds impact student outcomes. These changes apply to all public school districts in Montana, aiming to make funding more equitable and accountable.
