Primary HB 155

Revise class four residential and commercial property taxes

Maddy summaryHB 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.

Primary HB 451

Revise tax increment financing districts to exclude debt service and certain school levies

Maddy summaryHB 451 revises how tax increment financing (TIF) is calculated for newly established targeted economic development districts and urban renewal areas. For districts created after the bill's effective date, it excludes several specific mill levies from the tax increment calculation. These exclusions include certain university system mills, a portion of elementary, high school, and state equalization mills, new voter-approved levies, and mills for general obligation bond debt service. This means that a larger share of the new property tax revenue generated in these areas would directly go to the affected taxing jurisdictions, rather than into the TIF fund.

Revising membership in FURS to include airport authority public safety employees

Maddy summaryHB 640 would revise the Firefighters' Unified Retirement System (FURS) to allow certain airport authority employees to participate. The bill defines "public safety officer" as an airport authority employee who serves as both a full-paid firefighter and a sworn peace officer. It would permit airport authorities to elect to join FURS for these public safety officers, who are currently covered by the Public Employees' Retirement System. Existing eligible employees would have 90 days to choose whether to remain in PERS or join FURS.

Increase on-schedule reimbursement rates for school transportation

Maddy summaryHB 405 proposed to increase the maximum reimbursement rates that school districts receive from state and county sources for student transportation.

These funds are specifically designated for providing loans to develop and preserve homes and apartments for eligible persons. The bill also outlines project requirements, such as loans being for multifamily rental housing projects and adhering to specific interest rate guidelines.

Allow taxpayers to elect to receive electronic correspondence from the department of revenue

Maddy summaryHB 91 allows Montana taxpayers to choose receiving letters, notices, and other communications from the Department of Revenue electronically instead of by paper.

The bill requires the department to create rules for implementing this electronic option and takes effect immediately upon enactment. This change directly affects all Montana taxpayers who interact with the Department of Revenue for tax matters.

Deposit non-levy revenue in school equalization and property tax relief account

Maddy summaryHB 18 redirects all revenue from bentonite mining taxes (collected after December 31, 2014) to a dedicated "school equalization and property tax relief account" instead of previous distribution rules. Specifically, 20.75% of this tax revenue must now fund school districts and reduce local property taxes, as amended in sections 15-39-110 and 20-9-331 of Montana law. The bill directly affects mineral producers who pay the tax and school districts that receive funding through the new account. This change applies to all bentonite mining revenue collected after 2014, shifting funds from prior county and state allocations to the equalization account.

Revise terms for forest lands taxation advisory committee

Maddy summaryHB 17 revises the appointment terms and expiration dates for members of Montana's Forest Lands Taxation Advisory Committee. It specifies that legislative leaders must appoint committee members by July 1 of a regular session, with initial terms set to two years (instead of four), and requires replacement if an appointed legislator leaves their chamber early. The governor must appoint members annually, with initial terms ranging from one to four years (one for 1 year, one for 2 years, one for 3 years, and two for 4 years). The bill takes effect immediately upon enactment and does not change the committee's responsibilities or the forest land valuation system it advises on.
