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.
SB 424 would have expanded Montana's disabled veteran property tax assistance program to include veterans rated 60% to 90% disabled (previously only 100% or 80%+). It updated tax rate reductions based on income, adding new multipliers for 80-90% disabled veterans (e.g., 70% reduction for $0-$45,803 income) while maintaining existing rates for 100% disabled veterans. The bill directly affected disabled veterans with 60-90% service-connected disabilities (or surviving spouses) who own and occupy their primary residence as a qualifying property. The proposed changes were not enacted, as the bill was vetoed by the governor on June 9, 2025, and the veto override failed on July 14.
SB 537 revises Montana's marijuana tax revenue distribution, directing funds from the marijuana state special revenue account to new and existing state accounts. It requires transferring excess funds annually to specific accounts, including 12% to the HEART account for addiction treatment and mental health programs, 20% to wildlife habitat projects, and 14% to behavioral health initiatives. The bill also allocates funds for law enforcement canine training, sexual assault evidence kits, and homeless shelter support, while modifying existing transfer rules for agencies like the Department of Fish, Wildlife, and Parks. These changes apply to all state agencies receiving marijuana tax revenue under Montana law.
SB 536 revises Montana's contractor gross receipts tax by creating an exemption for certain individuals and businesses in good standing, requiring them to apply for the exemption. It specifically allows employee stock ownership plan (ESOP) companies to claim a credit against real property taxes, extending the timeframe to claim this credit from 5 to 7 years. The bill also clarifies that this credit can offset property taxes paid in Montana for business-related property. These changes apply to contractors with public contracts exceeding $80,000 and take effect January 1, 2026.
SB 171 requires that 10% of excess state general fund revenue, after meeting budget stability and capital projects fund thresholds, be transferred to the Montana coal severance tax permanent fund (coal trust fund). This bill amends Montana's budget law to direct a portion of surplus funds - specifically, funds exceeding established reserve levels - to the coal trust fund instead of remaining in the general fund. The transfer applies when the budget stabilization reserve fund and capital projects fund exceed 16% and 12% of general revenue appropriations, respectively. The coal trust fund, which supports coal-related programs, would receive this additional funding without altering the state's primary budget processes.
SB 205 would have revised Montana's voter approval requirements for local property tax levies and bond elections. It would have increased the minimum voter turnout threshold for county bond elections from 30% to 40% (requiring 50%+ of votes cast to approve), and raised the threshold for city/town bond elections from 40% to 50% turnout (also requiring 50%+ of votes cast). These changes directly affected counties and municipalities seeking voter approval for bond measures or mill levies. The bill died in process in May 2025 and did not become law.
SB 32 revises Montana's property tax structure by adjusting tax rates for multiple property classes. It lowers the tax rate for mining property (Class 2) from 3% to 1.65% of gross proceeds, sets agricultural land (Class 3) at 1.65% of productive value, and modifies residential/commercial rates (Class 4), including a reduced 1% rate for owner-occupied homes and a 1.4x multiplier for properties over $1.5 million. The bill also adds an inflation adjustment for local government tax levies and clarifies definitions for properties like nonproductive mining claims and owner-occupied residences. These changes directly affect property owners across Montana, particularly in agriculture, mining, and residential real estate.
SB 203 would increase Montana's income tax thresholds, meaning more income would be taxed at the lower 4.7% rate instead of the higher 5.9% rate. Specifically, it raises the income level before the higher rate applies to $200,000 for joint filers, $150,000 for heads of household, and $100,000 for single filers. This change affects all Montana individual income taxpayers, potentially reducing their tax burden for income falling within the new, higher thresholds. The bill also includes retroactive application to tax years beginning after December 31, 2024.
SB 2 clarifies how local governments calculate property tax levies when a tax increment financing (TIF) district ends. It specifies that the value previously held in the TIF district (the "increment") must be treated as "newly taxable property" for tax calculations in the year of termination or the following year. This directly affects Montana local governments, as it ensures they can include this value when determining property tax revenues under existing levy formulas, without treating it as new construction or annexation. The bill amends Montana Code Annotated sections 15-10-420 and 20-9-336 to define these rules clearly.
SB 322 increases Montana's tax exemption for business equipment by setting a $500 threshold, meaning equipment costing under $500 would be automatically exempt from taxation. It also requires annual inflation adjustments to the exemption amount and modifies tax code sections to clarify definitions and eligibility. Local governments and tax increment financing districts would receive reimbursements for lost property tax revenue due to these changes. The bill directly affects Montana businesses purchasing equipment under $500 and local governments managing property tax revenue.
