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 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 254 prohibits Montana local governments (including counties, cities, towns, and school districts) and judicial officers from using public funds to hire lobbyists or pay organizations that hire lobbyists on their behalf. It allows public officials to use public funds for travel and expenses related to lobbying on behalf of their entity, following standard per diem rates. The bill also enables taxpayers or residents to sue to stop prohibited spending and recover attorney fees if they win such cases, ensuring government entities cannot use taxpayer money to influence legislation through lobbying.
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 549 would have provided Montana taxpayers with a $1,250 annual income tax credit for eligible K-12 education expenses paid for children in public schools. It directly affected parents, guardians, and teachers of public school students by covering costs like tuition, textbooks, online learning programs, educational therapies, and school supplies. The credit would apply to expenses paid to public schools or specific accredited/non-accredited providers (with disclosure), but could not exceed a taxpayer’s total tax liability. The bill aimed to offset rising education costs for families in Montana’s public education system. (Note: This bill died in committee in May 2025 and did not become law.)
SB 434 provides a property tax rebate of up to $400 for Montana homeowners who lived in their principal residence for at least 7 months during tax year 2024. It directly affects individual homeowners (not businesses or multiple properties) who paid Montana property taxes on their primary residence, with the rebate amount capped at $400 or the actual taxes paid, whichever is lower. To claim the rebate, homeowners must submit an application electronically (August 15-October 1, 2025) or by mail (postmarked by October 1), including proof of residency and property ownership. The rebate is not subject to Montana income tax, and false claims may result in penalties of 300% of the rebate plus 12% annual interest.
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.
HB 313 aimed to establish a grant program to provide funding for public swimming pools operated by local governments and nonprofit organizations. It would have created a "public swimming pool infrastructure account" and appropriated $5 million from the state general fund, to be administered by the Department of Commerce. These grants were intended to support capital construction, maintenance, repair projects, and equipment purchases for eligible aquatic facilities. Grants of $25,000 or more would have required a 1:5 match, and funding was limited to $1 million per county and $500,000 per project.
