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 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.

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 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.

HB 924: Generally revise state finance laws

HB 924 creates the Montana Growth and Opportunity Trust, funded by half of the state's unpredictable revenue (like capital gains or oil royalties) starting in 2027. Interest income from the trust is split: half distributes $15 million annually to five specific programs (disaster resiliency, property tax relief, water development, bridge repairs, and early childhood care), while the other half reinvests in pension funds and housing infrastructure. The bill establishes new accounts for these programs and sets rules for calculating volatile revenue using historical data to stabilize budgeting. It directly affects state budgeting, early childhood services, infrastructure projects, and pension systems through mandatory funding allocations.
