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 119 sought to establish the Montana Cattle Committee, a new entity composed of seven Montana cattle producers appointed by the governor. The committee would be responsible for planning and conducting research, promotion, and educational programs to benefit the state's cattle industry. To fund these activities, the bill proposed a cattle assessment to be collected from cattle sellers, which would first require approval through a referendum of those sellers. Funds from this assessment would be deposited into a dedicated cattle special revenue account for the committee's use.
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.
House Resolution 7 (HR 7) requests that members of the Montana State Legislature, when introducing or amending bills to include new spending, also identify existing programs from which funds would be reallocated to cover those new appropriations. This means any bill proposing new expenditures would need to specify how those funds would be offset within the state budget.
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 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 369 authorizes the creation of county road maintenance districts to maintain roads that were previously serviced by the county but owned by other entities. These districts can be formed when at least 66% of property owners in a proposed area petition the county commissioners. The districts are funded by assessing maintenance costs directly against the benefited properties within the district. The amount assessed by a district must then be subtracted from the county's general fund dedicated to road improvement or maintenance.
HB 537 proposed creating a new "birth day" tax credit for resident taxpayers in Montana upon the birth of a child. The credit would be up to $3,000, or the total of the taxpayer's Montana income taxes, federal income taxes, and FICA contributions, whichever is less. This credit would be refundable, allowing taxpayers to receive a refund even if they have no state tax liability. The credit amount would be reduced for higher-income taxpayers and capped at $1,500 in certain situations, such as for parents filing separately or unmarried parents sharing custody. If passed, it would have applied to income tax years beginning after December 31, 2025.
