SB 437 revises the definitions of "sex," "female," "male," "man," "woman," "father," and "mother" within Montana law. The bill defines "sex" exclusively as biological sex, determined by reproductive anatomy, chromosomes, gonads, and genitalia present at birth. It clarifies that sex is limited to two categories, male and female, and is not influenced by an individual's gender identity, psychological state, or personal experience. This legislation amends numerous sections of the Montana Code Annotated to reflect these updated biological definitions.
HB 259 revises Montana's gray wolf management rules to give the Fish and Wildlife Commission more flexibility in controlling wolf populations. It allows landowners to kill wolves threatening livestock or safety without a hunting license (subject to reporting and annual quotas), expands hunting/trapping on private land at night using thermal/infrared scopes, and permits unlimited wolf harvest in high-population areas. The bill directly affects landowners, hunters, and the Fish and Wildlife Commission, which must implement these changes. Key provisions include new landowner take rules, modified hunting seasons based on regional wolf numbers, and immediate implementation upon enactment.
HB 831 increases Montana's elderly homeowner and renter income tax credit to help low-to-moderate-income seniors. It raises the maximum credit from $1,150 to $1,400 and increases the household income threshold for eligibility from $35,000 to $50,000 before the credit phases out. The bill also requires annual inflation adjustments to maintain the credit's value and applies retroactively to tax years beginning after December 31, 2024. This directly benefits Montanans aged 65+ who own or rent homes and meet the updated income limits.
HB 628 updates Montana's early literacy program to include broader academic skills ("scholastic literacy") and adjusts enrollment rules for school districts. It allows districts to enroll up to one student already meeting grade-level reading/math expectations ("on-target") for every three students needing intervention in classroom or Jumpstart programs. The bill directly affects kindergarten through 3rd-grade students in Montana public schools identified as below reading/math proficiency, with school districts using state-approved assessments to determine eligibility. Key changes include expanding the program's scope beyond basic reading and modifying enrollment ratios to better align student needs with available support.
HB 643 revises how state agencies pay for holding people in county detention centers. It changes the definition of "actual costs" to be the greater of either $82 per day (as documented by the center) or 90% of the Crossroads Correctional Facility's daily rate. This affects the Department of Corrections, Department of Public Health and Human Services, and local law enforcement agencies that must pay these costs for specific cases, like probation violators or people awaiting placement in health facilities. The bill ensures payments cover the documented costs plus 10%, clarifying which agency pays in different detention scenarios.
SB 410, the Montana Genomic Security Act, prohibits medical and research facilities in Montana from using genetic sequencers or sequencing software produced by companies based in nations designated as "foreign adversaries" under federal regulations (e.g., China, Russia). Facilities must replace such technology, store all genetic data within the U.S., and obtain written consent for remote data access outside Montana. The bill requires annual compliance certifications to the Attorney General and imposes $10,000 fines per violation for noncompliance with data storage or technology bans. It directly affects hospitals, research labs, and health facilities receiving state funding or conducting genetic research.
HB 861 allocates $1.1 million annually to Montana's Office of Public Instruction and $750,000 to the Department of Labor and Industry for fiscal years 2026 and 2027. The funds will provide statewide access to a K-12 digital toolkit containing state standards-aligned instructional materials across all subjects, including career and technical education resources aligned with Montana industry needs. This bill directly affects Montana public schools and students by expanding access to digital learning tools. It establishes a permanent funding base for these resources, effective July 1, 2025, though it was vetoed and not enacted.
HB 585 would have revised Montana's Medicaid reimbursement rates for physical therapists, speech-language pathologists, and occupational therapists. It set a 2026 Medicaid payment rate of $39.56 per service unit and required annual rate increases tied to the medical care component of the U.S. Consumer Price Index. This directly affected these healthcare providers who bill Medicaid for services, ensuring their payments adjusted with inflation. The bill was introduced in 2025 but was vetoed by the governor and later failed to override in the legislature.
SB 422 requires Montana health insurers to cover FDA-approved drugs for advanced or metastatic cancer without forcing patients to first fail other treatments. It prohibits insurers from demanding that patients prove they've tried and failed alternative drugs before approving coverage for new treatments that align with national cancer guidelines. This directly affects patients diagnosed with advanced or metastatic cancer in Montana, ensuring faster access to potentially life-saving medications without unnecessary bureaucratic hurdles. The law applies only to drugs approved by the FDA and consistent with evidence-based cancer treatment protocols.
SB 188 establishes Montana's "Solar Shares Act," creating a new framework for shared solar energy programs. It defines "shared solar facilities" (50kW-5MW systems serving multiple customers in the same utility area) and requires utilities to interconnect them, replacing net metering with "on-bill credits" for subscribing customers. Key provisions include: utilities must apply credits to subscribers' bills based on their share of generation, facilities must be within the utility's service territory, and credits can transfer between accounts or support low-income programs. The bill directly affects public utilities, shared solar facility owners, and residential/commercial customers who subscribe to shared solar.
SB 424 would have expanded Montana's disabled veteran property tax assistance program to include veterans rated 60% to 90% disabled (previously only 100% or 80%+). It updated tax rate reductions based on income, adding new multipliers for 80-90% disabled veterans (e.g., 70% reduction for $0-$45,803 income) while maintaining existing rates for 100% disabled veterans. The bill directly affected disabled veterans with 60-90% service-connected disabilities (or surviving spouses) who own and occupy their primary residence as a qualifying property. The proposed changes were not enacted, as the bill was vetoed by the governor on June 9, 2025, and the veto override failed on July 14.
SB 537 revises Montana's marijuana tax revenue distribution, directing funds from the marijuana state special revenue account to new and existing state accounts. It requires transferring excess funds annually to specific accounts, including 12% to the HEART account for addiction treatment and mental health programs, 20% to wildlife habitat projects, and 14% to behavioral health initiatives. The bill also allocates funds for law enforcement canine training, sexual assault evidence kits, and homeless shelter support, while modifying existing transfer rules for agencies like the Department of Fish, Wildlife, and Parks. These changes apply to all state agencies receiving marijuana tax revenue under Montana law.
