HB 831: Increase elderly homeowner and renter income tax credit

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: Revise early literacy targeted intervention laws

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.

SB 410: Provide for Montana genomic security act

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: Provide statewide access to a K-12 digital toolkit

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: Revise provider rate laws for physical therapists, speech-language pathologists, and occupational therapists

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 437: Revise definition of sex in Montana law

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: Revise fish and wildlife commission techniques for gray wolf management

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 643: Revise reimbursement costs to detention centers holding inmates in state custody

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.

HB 5: Long-range building appropriations

HB 5 appropriates over $30 million for major repair and capital development projects across Montana state facilities, including universities, health departments, and government buildings, for the 2023-2025 biennium. It funds specific upgrades like roof replacements, heating system repairs, fire safety improvements, and electrical system modernizations at locations such as Montana State University campuses, the Department of Health facilities, and state prisons. The bill increases the value threshold for certain projects from $150,000 to $300,000 and authorizes transfers between state fund accounts to support these repairs. It directly affects state agencies managing public infrastructure by providing dedicated funding for essential maintenance and safety upgrades. The bill was enacted on June 19, 2025, after passing both legislative chambers.

HB 2: General Appropriations Act

HB 2, the General Appropriations Act of 2025, allocates $30.8 million in state funding for Montana's agencies during the 2025-2027 biennium. It directly affects all state agencies receiving funds, including the Legislative Services Division, Governor's Office, and Consumer Counsel, by specifying how money can be spent (e.g., "Biennial" funds for two years, "Restricted" funds for specific purposes). Key mechanisms include categorizing appropriations to control spending, requiring separate budget tracking for different fund types, and mandating clear reporting of personal services funding. The bill does not create new policies but establishes the financial framework for state operations during the biennium.
