HB 841 proposed a constitutional amendment in Montana to change the allocation of state sales or use tax revenue. It would have required that revenue from a statewide sales tax, capped at 4%, be used primarily to reduce property taxes funding public schools and the Montana University System. The bill allowed for this revenue to be appropriated for other purposes if three-fourths of the legislature voted to do so. If approved by voters in November 2026, the amendment would have taken effect on July 1, 2027.
HB 461 proposes a property tax exemption for certain owner-occupied residential properties. It directly affects homeowners aged 65 or older who have continuously used the property as their primary residence for at least five years. The exemption amount is calculated based on the increase in market value compared to a "base year" when the exemption was first approved. Homeowners must apply annually by March 1, and the exemption can terminate if the property is sold, undergoes new construction or significant remodeling, or is reclassified.
HB 507 is a proposed constitutional amendment that would allow Montana to implement a 4% statewide sales tax (and use tax) specifically to reduce property taxes funding K-12 public schools. If approved by voters, this tax revenue would replace some local property tax funding for schools, directly affecting Montana taxpayers and public school districts. The bill requires a two-thirds legislative vote for passage and voter approval in the November 2026 election, with an effective date of July 1, 2027 if adopted. The bill was withdrawn by the House on February 27, 2025, per procedural rules, and did not advance further.
HB 25 proposed that entities typically exempt from property taxes, such as government bodies or charities, would need to report annually to the Department of Revenue. This report would be required if they lease their property to a non-exempt entity or for a non-exempt use, and would include a description of the leased property and a copy of the lease agreement. If the beneficial use of the property was not properly reported, it would become subject to property taxation. The bill aimed to ensure that properties used for non-exempt purposes are appropriately taxed, even if owned by an exempt organization.
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.
HB 489, titled the "Local Option Property Tax Relief Act," would have allowed consolidated city-counties or counties to implement a local sales tax. This tax, requiring voter approval and capped at 4%, would apply to specific goods and services, excluding items like medical supplies and SNAP-eligible food products. The revenue generated from this local option tax would be specifically used to provide property tax relief for primary residences and long-term rental properties. A portion of the revenue would also be distributed to local governments that do not levy the tax.
HB 412 proposed a new property tax exemption for homeowners who modify their existing residential properties to add living space. This exemption would apply to the increase in market value due to the modification, up to a limit of 15% of the property's market value before the modification. However, it would not apply to modifications made within three years of new construction, and only one exemption could be granted every six years, terminating upon the sale of the property. The Department of Revenue would automatically grant this exemption, which was set to begin in tax years after December 31, 2025.
HB 887 was a legislative bill designed to provide property tax assistance for owners of primary residences. The bill proposed to fund this relief by redirecting a portion of the state's lodging tax revenue. It aimed to amend existing statutes governing the distribution of these lodging tax proceeds. While the bill's intent was to reallocate lodging tax funds for property tax relief, the provided text does not detail the specific changes or mechanisms for how these funds would be redirected.
HB 946 aimed to provide property tax relief for owners of principal residences by increasing selective sales taxes on lodging and rental cars. The bill proposed a temporary property tax credit of up to $400 for eligible principal residences for tax year 2025, based on 2024 tax payments. It also outlined plans for permanent property tax assistance starting in tax year 2026. The Department of Revenue would have been responsible for certifying principal residences and processing claims, which included an application and appeals process.
HB 27 revises the criteria for classifying land as agricultural for property tax valuation. The bill introduces an application and review process for certain agricultural properties, moving away from automatic classification. It also increases the required annual gross income for parcels between 20 and 160 acres to qualify as agricultural land. Furthermore, it establishes a new "idle land" classification with a revised tax rate, replacing the prior "nonqualified agricultural property" classification, directly affecting property owners with these land types.
