HB 528 revises Montana property tax rates for agricultural, residential, and commercial property. It lowers the tax rate for class three agricultural land from 2.16% to 1.7% of its productive capacity value, and reduces the tax rate for class four residential property from 1.35% to 0.76% of market value. Commercial property rates remain at 1.35% of market value but include specific adjustments for properties over $1.5 million in value. The bill applies retroactively to tax years beginning after December 31, 2024, and the 2025 reappraisal cycle.
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 451 revises how tax increment financing (TIF) is calculated for newly established targeted economic development districts and urban renewal areas. For districts created after the bill's effective date, it excludes several specific mill levies from the tax increment calculation. These exclusions include certain university system mills, a portion of elementary, high school, and state equalization mills, new voter-approved levies, and mills for general obligation bond debt service. This means that a larger share of the new property tax revenue generated in these areas would directly go to the affected taxing jurisdictions, rather than into the TIF fund.
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 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 228 revises how the Office of Budget and Program Planning reports on the actual costs of certain legislation to the Legislative Finance Committee. It lowers the threshold for tracking from $1 million to $500,000 in projected general fund expenditures. The bill requires reports to be submitted biannually, in February and October, detailing actual spending for the preceding six months and comparing it to the original projected costs. This legislation also repeals a termination date, making this cost reporting requirement permanent.
House Bill 864 implements provisions related to education funding and administration across various institutions. It expands the use of the School Facility and Technology Account, allowing excess funds to be transferred to the School Major Maintenance Aid Account to prevent aid reductions for schools. For community colleges, the bill revises definitions and mechanisms for calculating state general fund appropriations, incorporating inflationary adjustments and changes in full-time equivalent (FTE) student numbers. It also increases payments for resident nonbeneficiary students at tribal colleges and mandates a study on interlibrary resource sharing programs and the Office of Public Instruction.
