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 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 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.
SB 324 revises vehicle registration fees for high-end vehicles, adding a 1% fee based on the vehicle's manufacturer's suggested retail price (MSRP) for the first year of registration after January 1, 2026, for cars over $150,000 and motorhomes over $300,000. It directly affects owners of these high-value vehicles, replacing a flat annual add-on fee with the percentage-based assessment. Revenue from these fees will fund two specific programs: grants for bridge projects through the Department of Transportation and services for crime victims via the Board of Crime Control. The bill also updates related sections of Montana law governing registration fees and special revenue accounts.
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.
SB 99 amends Montana tax law to treat certain rental and accommodations income earned by tax-exempt organizations as "unrelated business income" subject to taxation. This affects nonprofits and other exempt groups that previously did not pay tax on such income, including short-term rentals or property leasing activities. The bill creates new reporting requirements for these organizations and specifies how to calculate the tax based on Montana’s existing tax rates and sourcing rules. It modifies existing statutes to clarify that this income must now be included in taxable income calculations, rather than remaining exempt. The change applies to income generated from business activities unrelated to the organization’s exempt purpose.
