SB 405 proposed transferring $50 million from Montana's general fund to the Housing Montana Fund within 15 days of enactment, directly supporting state housing programs and affordable housing initiatives. It required the Department of Commerce to update administrative rules related to housing by the start of the 70th legislative session. The bill would have taken effect July 1, 2025, but died in committee on May 23, 2025, after being tabled in April 2025. This was a substantive funding bill, not a procedural measure, with no further legislative action taken.
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 848 aimed to provide dedicated funding for regional rail authorities in the state. The bill proposed creating a "Big Sky Rail Account" within the state special revenue fund, which would receive a portion of rental car sales and use tax proceeds. The Department of Transportation would then annually distribute these funds to eligible regional rail authorities. These authorities could use the money for administrative costs, matching federal grants, fostering partnerships, and planning, developing, and operating rail projects and services, such as enhancing safety, improving stations, and exploring new train routes.
HB 851 proposes to create a new state agency called the Department of Health Services. This new department would take over specific human services functions currently managed by the Department of Public Health and Human Services. These transferred responsibilities include the administration of developmental disabilities services, mental health services (like the Montana State Hospital), chemical dependency services, and veterans' long-term care facilities. The bill also provides an appropriation for the new department, grants it rulemaking authority, and requires its contracts to include dispute resolution clauses.
HB 836 proposed creating a property tax deferral loan program for eligible senior citizens and active-duty military personnel in Montana. This program would allow qualifying homeowners to defer paying the portion of their property taxes that exceeds their 2022 property tax amount. The state's Board of Housing would provide these loans, which would accrue simple interest and become a lien on the primary residence. The loan, including interest, would generally be repaid when the property is sold or transferred, or upon the death of the homeowner, though a surviving spouse might be able to assume the loan.
HB 155 revises property tax laws for Class Four residential and commercial properties. For residential properties, it introduces a graduated tax rate for single-family homes above $1.5 million in market value and sets specific rates for vacant residential lots under $50,000 and certain rental multifamily units over $2 million. For commercial and industrial properties, the bill exempts the first $200,000 of market value from taxation and establishes specific tax rates for the remaining value, with a different rate for golf courses. The bill would have taken effect immediately and applied retroactively to property tax years beginning after December 31, 2024.
HB 154 would have created a new tax credit for Montana renters and homeowners with household incomes under $150,000. The credit would equal 75% of either property taxes paid (for homeowners) or 15% of rent paid (for renters), minus an income-based percentage (ranging from 1% to 9.5%). To qualify, residents needed to have lived in Montana for at least 9 months and occupied a home or rental for 6 months during the tax year. The bill died in committee in May 2025 without becoming law.
HB 220 would establish a refundable child tax credit for Montana resident taxpayers with children under age 5. It provides a $1,200 credit per qualifying child, phasing out for taxpayers with federal adjusted gross income over $56,000 (with a $50,000 phaseout threshold). The credit is refundable, meaning eligible families could receive it as a payment even if they owed no state income tax. The bill also adds the child tax credit to Montana’s required periodic review schedule for tax credits. The bill died in committee on May 22, 2025, and did not become law.
HB 424 revises property tax classifications for data center property. It modifies the types of property included in Class seventeen for qualified data centers, and extends the timeframe within which this data center property must be built. The bill also revises ownership requirements for Class seventeen data center property. Additionally, it updates the classification of certain dedicated communications infrastructure in Class thirteen, extending its relevant timeframe.
HB 329 aims to encourage the formation of ammunition component manufacturing businesses in Montana. It establishes various state tax exemptions for qualified manufacturers, including property, individual income, corporate income, and other business-related taxes. To receive these exemptions, manufacturers must make their products available to in-state consumers at prices no higher than those for out-of-state purchasers. Additionally, the bill provides individual and corporate income tax exemptions to investors and lenders who provide loans to these eligible ammunition component manufacturers.
