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 159 would create an "Educational Opportunity Fund" within Montana's coal severance tax trust. It increases the annual cap on educational tax credits from $2 million to $5 million starting in 2024, with automatic annual increases of 20% plus 50% of fund earnings. This bill directly affects taxpayers who donate to school districts for innovative programs or to scholarship organizations, allowing them to claim larger tax credits. It also removes the previous sunset provision, making the credit program permanent. The bill amends existing tax code sections to implement these changes to educational funding.
SB 169 would revise Montana's property tax law by removing the tax exemption for certain intangible personal property, such as stocks, bonds, patents, software, and licenses, unless they are directly used in business operations. This change would affect businesses and property owners holding these assets, requiring them to pay property taxes on previously exempt items. The bill clarifies that intangible property lacking physical existence (like goodwill) or representing value (like financial instruments) is no longer exempt, while property integral to business operations remains exempt. The law would take effect for tax years beginning after December 31, 2025, with implementation starting January 1, 2026.
SB 267 (Montana Senate Bill 267) creates a 50% tax credit for Montana taxpayers who make charitable donations to certified public infrastructure projects, capped at $500,000 annually. The credit applies to donations for government-owned facilities like health clinics, senior centers, libraries, and museums that serve public educational, health, or civic needs. Taxpayers must receive certification from the state for the project, and any unused credit can be carried forward for up to three years. The bill died in the legislative process on May 23, 2025, after being tabled in committee and missing a deadline.
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 4 changes how Montana taxes the land beneath a home on qualifying agricultural property. It requires the first acre of land under a residence on eligible farm property to be valued at market rate but exempts it from tax up to the statewide average value for similar homesites. This primarily affects homeowners living on agricultural land who qualify for special farm tax treatment under Montana law. The exemption reduces their property tax burden specifically on that 1-acre parcel, rather than the entire farm.
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.
SB 554 (Montana) limits nonprofit hospitals (excluding critical access/rural emergency hospitals) to charging no more than 300% of the Medicare reimbursement rate for Medicare-eligible services. Hospitals exceeding this rate face an escalating excise tax (starting at 25% in 2027 and rising to 50% after 2030) and risk losing nonprofit status. The bill also requires hospitals to maintain written financial assistance and community benefit policies, submit annual reports including IRS Form 990, and comply with new reporting rules. This bill died in process in May 2025 and was never enacted.
SB 538 would allow Montana taxpayers to claim the same qualified business income deduction they use on their federal tax returns under Section 199A of the Internal Revenue Code. This directly affects Montana business owners who operate as sole proprietors, S-corps, or partnerships and qualify for the federal deduction. The bill amends Montana's tax code to automatically include this deduction when calculating state taxable income, aligning Montana's rules with the federal provision. It applies retroactively and takes effect immediately upon enactment. The bill died in committee in May 2025 and was not enacted.
