SB 192 would have imposed a 10% tax on digital advertising revenue generated within Montana by companies with worldwide annual digital advertising revenue exceeding $25 million. It directly affects large digital advertisers (like major tech or social media platforms) operating in Montana, taxing only the portion of their revenue derived from ads served to Montana users. The tax would be calculated using an apportionment method based on Montana ad revenue relative to total U.S. ad revenue, with returns due annually by April 15. All collected revenue would have been deposited into Montana's general fund, as specified in the bill's provisions. The bill died in committee in May 2025 and was not enacted.
SB 157 would have allowed Montana taxpayers who itemize deductions on their federal tax returns to deduct up to 150% of their charitable contributions from their Montana state income tax. This provision, added to Montana's tax code, would have directly affected individual filers who itemize federal deductions and make charitable gifts. The bill proposed a specific mechanism where the state deduction amount would be calculated as 150% of the federal charitable deduction amount claimed. However, the bill was tabled in committee and later died in the legislative process in May 2025, so it did not become law.
SB 102 limits annual revenue growth for specific education levies in Montana. It caps the increase in property tax revenue from state school equalization levies and vocational-technical education levies at no more than 3% above the previous year's total. The bill also prevents school districts from carrying forward unused mill authority (property tax rate authority) for these specific levies. This directly affects school districts that rely on these levies for funding, ensuring their revenue growth cannot exceed 3% annually without voter approval. The policy change applies to the calculation method for these levies as outlined in Montana law.
SB 225 would create a refundable income tax credit for Montana renters with household income under $45,000. The credit equals the lesser of 4% of rent paid above household income or $500, phasing out completely for incomes of $45,000 or more. It directly affects low-to-moderate-income renters who pay rent in Montana, providing a refund even if they owe no income tax. The bill also amends tax code sections to include this credit in regular review cycles and prohibits claiming it alongside the existing elderly property tax credit.
SB 150 creates a new "cigar bar room" license endorsement for existing alcohol licensees that also hold gambling licenses (e.g., casinos or gaming venues). It allows premium cigar smoking only in a designated, enclosed area with strict requirements: cigars must meet specific handmade criteria (no filters, 100% tobacco), the venue must generate at least 10% of annual revenue from cigar sales, and no other tobacco/vaping products may be smoked or sold there. The designated area must have proper ventilation, be separate from nonsmoking zones, and exclude minors under 21. The bill also exempts these cigar rooms from standard clean indoor air laws and requires a 2026 study on Montana’s gaming industry.
SB 558 proposed replacing school property taxes with a statewide sales tax to fund public schools. It would create a new general sales tax, redirect all revenue to a dedicated school funding account, and repeal existing statewide property tax levies for schools. The bill would directly affect school districts and property taxpayers by shifting funding responsibility from local property taxes to a statewide sales tax, with certain exemptions (like agricultural sales) specified. However, the bill was tabled in committee and died in the legislative process in 2025, so it never became law.
SB 551 would establish a licensing system for online fantasy sports companies operating in Montana, requiring them to obtain approval from the Department of Justice. It defines "fantasy sports contests" as skill-based games where outcomes depend on player knowledge (not chance), mandates background checks for applicants, and sets fees for licensing and criminal background investigations. The bill also creates tax rules based on "internet fantasy sports contest adjusted revenues" and requires companies to maintain records for audits. This bill died in committee in May 2025 and did not become law.
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 351 limits Montana local governments' ability to save ("bank") property tax authority for certain state-mandated tax programs. It specifically amends property tax law to prevent local entities from carrying forward unused mill authority (tax rate allowances) for taxes imposed under statutes 20-9-331, 20-9-333, 20-9-360, and 20-25-439. This change directly affects counties, cities, and school districts that rely on these specific state tax programs, requiring them to use their full annual tax authority each year rather than saving it for future use. The bill’s key provision removes these programs from the existing rule that allows governments to carry forward unused tax authority to future years.
