Budget & Taxes

SB 99 amends Montana tax law to treat certain rental and accommodations income earned by tax-exempt organizations as "unrelated business income" subject to taxation. This affects nonprofits and other exempt groups that previously did not pay tax on such income, including short-term rentals or property leasing activities. The bill creates new reporting requirements for these organizations and specifies how to calculate the tax based on Montana’s existing tax rates and sourcing rules. It modifies existing statutes to clarify that this income must now be included in taxable income calculations, rather than remaining exempt. The change applies to income generated from business activities unrelated to the organization’s exempt purpose.

HB 560 would have established a Montana Hunters' and Anglers' Community Fund, allowing donors to contribute $1 or more above the cost of wildlife conservation licenses. Funds collected would support grants for small rural communities (under 7,500 people) through the Department of Commerce, including projects like school improvements, food banks, or student programs. Grants would be limited to $2,000 (small) or $20,000 (large), with eligibility restrictions barring political activities and entities involved in lawsuits. The bill created a review board appointed by legislative leaders and the governor, and it died in committee in May 2025 without becoming law.

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.

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 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.
