SB 4 changes how Montana taxes the land beneath a home on qualifying agricultural property. It requires the first acre of land under a residence on eligible farm property to be valued at market rate but exempts it from tax up to the statewide average value for similar homesites. This primarily affects homeowners living on agricultural land who qualify for special farm tax treatment under Montana law. The exemption reduces their property tax burden specifically on that 1-acre parcel, rather than the entire farm.
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 322 increases Montana's tax exemption for business equipment by setting a $500 threshold, meaning equipment costing under $500 would be automatically exempt from taxation. It also requires annual inflation adjustments to the exemption amount and modifies tax code sections to clarify definitions and eligibility. Local governments and tax increment financing districts would receive reimbursements for lost property tax revenue due to these changes. The bill directly affects Montana businesses purchasing equipment under $500 and local governments managing property tax revenue.
SB 538 would allow Montana taxpayers to claim the same qualified business income deduction they use on their federal tax returns under Section 199A of the Internal Revenue Code. This directly affects Montana business owners who operate as sole proprietors, S-corps, or partnerships and qualify for the federal deduction. The bill amends Montana's tax code to automatically include this deduction when calculating state taxable income, aligning Montana's rules with the federal provision. It applies retroactively and takes effect immediately upon enactment. The bill died in committee in May 2025 and was not enacted.
SB 274 expands Montana's disabled veteran property tax assistance program to include veterans rated 60% to 90% disabled (previously limited to 100% disabled), directly affecting eligible veterans and surviving spouses. It revises eligibility definitions in Sections 15-6-301 and 15-6-311, MCA, to clarify qualifying income levels and requires annual adjustments using the PCE inflation factor to maintain benefit value. The bill also specifies that surviving spouses must provide VA documentation showing the veteran was rated 60%+ disabled at death. The changes would apply to property tax years beginning after December 31, 2025, with the bill taking effect immediately upon enactment.
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 371 would create a tax incentive by allowing Montana taxpayers to subtract income from Montana-produced goods from their individual and corporate income tax calculations. It directly affects businesses and individuals selling goods manufactured or grown within Montana, reducing their taxable income for those specific sales. The bill amends Montana's tax code to define "Montana-produced goods" and establish this subtraction as a specific adjustment to federal taxable income. This policy change aims to support local producers by lowering their state tax burden on sales of locally made products.
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.)
