HB 306 would have created an income tax credit for property owners, including individuals and corporations, who rent out dwellings in Montana for less than 110% of the fair market rent for their county. The credit amount would be $200 for each $100 difference between 110% of fair market rent and the actual monthly rent charged. To qualify, a dwelling would need a lease of at least one year and meet specific housing quality standards. This credit could be carried forward for up to three years if not fully utilized.
HB 337 revises Montana's income tax laws, affecting individual taxpayers and certain estates or trusts. The bill aims to lower income taxes by adjusting the state's tax brackets. It increases the amount of Montana taxable income taxed at lower rates and reduces the highest income tax rate. Additionally, the bill revises the tax rates and income thresholds applied to net long-term capital gains.
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 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.
SB 274 expands Montana's disabled veteran property tax assistance program to include veterans rated 60% to 90% disabled (previously limited to 100% disabled), directly affecting eligible veterans and surviving spouses. It revises eligibility definitions in Sections 15-6-301 and 15-6-311, MCA, to clarify qualifying income levels and requires annual adjustments using the PCE inflation factor to maintain benefit value. The bill also specifies that surviving spouses must provide VA documentation showing the veteran was rated 60%+ disabled at death. The changes would apply to property tax years beginning after December 31, 2025, with the bill taking effect immediately upon enactment.
SB 321 proposes three tax credits to support Montana families and child-care providers. It would provide a $1,200 annual credit per child under age 5 for eligible residents (with income limits of $40,000 single/$80,000 married filing jointly), a $1,000 credit for child-care workers employed at least 6 months (20+ hours weekly), and a $2,500 employer credit for businesses offering dependent care assistance. All credits adjust annually for inflation and require filing a Montana tax return. The bill directly affects low-to-moderate-income families, child-care workers, and employers who provide on-site or subsidized care. (Note: The bill died in committee on May 23, 2025, and did not become law.)
SB 534 provides a property tax exemption for specific wireless infrastructure in Montana. This bill exempts qualifying wireless infrastructure, placed into service on or after the act's effective date, from property taxes for an initial period of five years. Following this, the exemption gradually phases out over the next five years, after which the property becomes fully taxable. To maintain the exemption, owners must reinvest the tax savings into new communication infrastructure within Montana, without charging those costs to consumers.
HB 231 revises property tax laws by establishing reduced tax rates for certain class four residential and commercial properties. It provides a lower tax rate for qualifying owner-occupied principal residences and long-term rental properties, as well as for a portion of commercial property value. For principal residences, some owners will automatically qualify for the reduced rate for tax years 2025 and 2026 based on prior tax rebates or assistance programs. Beginning in tax year 2027, all owners seeking these reduced rates must apply to the department and meet specific eligibility criteria, such as demonstrating occupancy for a principal residence or rental periods for long-term rentals.
SB 204 would have limited most voter-approved property tax levies (mill levies) to a 10-year duration without requiring reapproval by voters. It directly affects local governments - including school districts, cities, and counties - that collect property taxes, requiring them to seek voter reapproval before existing levies expire. Key provisions include setting termination dates for all levies after 10 years (unless exceptions apply) and listing specific exceptions for school levies, community colleges, law enforcement, fire protection, and emergency medical services. The bill aimed to ensure ongoing voter oversight of property tax rates while maintaining stability for essential public services. (Note: The bill died in process on May 23, 2025, and did not become law.)
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.
