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 323 would reduce Montana's top individual income tax rate from 5.9% to 4.9% for most taxpayers, including married couples filing jointly, heads of household, and single filers. It also increases the state's Earned Income Tax Credit, providing greater tax relief for low-to-moderate income workers. The bill amends Montana's tax code (sections 15-30-2103 and 15-30-2318) to adjust tax brackets and credit amounts, with changes applying to income above specific thresholds ($41,000 for joint filers, $30,750 for heads of household, and $20,500 for others). The bill was tabled in committee and died in process without becoming law.
SB 203 would increase Montana's income tax thresholds, meaning more income would be taxed at the lower 4.7% rate instead of the higher 5.9% rate. Specifically, it raises the income level before the higher rate applies to $200,000 for joint filers, $150,000 for heads of household, and $100,000 for single filers. This change affects all Montana individual income taxpayers, potentially reducing their tax burden for income falling within the new, higher thresholds. The bill also includes retroactive application to tax years beginning after December 31, 2024.
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 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 90 would provide property tax relief to Montana homeowners with primary residences by using lodging and rental car tax revenue. Homeowners would need to apply for certification by March 1, proving they live in the home at least 7 months yearly and that the property value is under $1 million. Counties would apply the credit directly to property tax bills using annual funding based on certified residences, with penalties for false applications. The bill specifies that assistance won’t affect local mill rates and requires Department of Revenue certification of eligible primary residences.
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.
SB 343 would change how Montana allocates remaining coal severance tax revenue after other specified uses. Currently, until 2027, interest income from the coal trust fund is sent to the general fund for specific programs like agriculture development, small business centers, and library services. This bill amends the law to redirect all remaining coal tax revenue (after other allocations) directly to the coal severance tax permanent fund starting July 1, 2027, instead of the general fund. The policy change would shift funding away from current general fund programs toward the coal trust fund, which supports coal-dependent communities and projects.
