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 313 aimed to establish a grant program to provide funding for public swimming pools operated by local governments and nonprofit organizations. It would have created a "public swimming pool infrastructure account" and appropriated $5 million from the state general fund, to be administered by the Department of Commerce. These grants were intended to support capital construction, maintenance, repair projects, and equipment purchases for eligible aquatic facilities. Grants of $25,000 or more would have required a 1:5 match, and funding was limited to $1 million per county and $500,000 per project.
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 334 sought to revise laws concerning disaster and emergency funding. The bill proposed to increase the statutory appropriation available to the Governor's office for declared emergencies from $16 million to $22 million per two-year period, effective July 1, 2025. It also would have allowed the Department of Military Affairs to use up to $3 million annually from this fund for disaster and emergency services activities, such as planning, training, and response, without a formal governor's declaration. Unspent funds at the end of each biennium would continue to be transferred to the fire suppression account.
HB 827 aimed to revise the taxation of Social Security benefits at the state level in Montana. The bill proposed to modify how the federal calculation for taxing Social Security benefits is applied when determining an individual's state income tax. This change would have directly affected Montana residents receiving Social Security benefits by potentially altering the portion of those benefits subject to state income tax. The bill included provisions for a delayed effective and applicability date.
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.
HB 876, the Sawmill Revitalization Act, creates a special state revenue account to support the reopening of closed sawmills. It transfers $6 million from the big sky economic development fund into this account. The Board of Investments will administer these funds, offering loans at an interest rate not exceeding 3% to parties with the capacity to return closed sawmills to commercial operation. Priority for these loans is given to sawmills that closed most recently. This act is effective July 1, 2025, and terminates on December 30, 2026.
HB 9 appropriates funds for cultural and aesthetic projects across Montana for the biennium ending June 30, 2027. It allocates $30,000 from the cultural and aesthetic projects trust fund to the Montana Historical Society for capitol complex artwork care. Additionally, it appropriates $953,500 from the same fund to the Montana Arts Council, which will award grants to numerous listed cultural and artistic organizations. Grant recipients are required to acknowledge that the funding originates from coal tax placed into Montana's Cultural and Aesthetic Projects Trust Fund. Any unspent grant money will revert to the trust fund after June 30, 2027.
SB 534 provides a property tax exemption for specific wireless infrastructure in Montana. This bill exempts qualifying wireless infrastructure, placed into service on or after the act's effective date, from property taxes for an initial period of five years. Following this, the exemption gradually phases out over the next five years, after which the property becomes fully taxable. To maintain the exemption, owners must reinvest the tax savings into new communication infrastructure within Montana, without charging those costs to consumers.
