The Montana Legislature convened on March 29, 2025, to introduce Senate Bill 540, a legislative proposal aimed at amending property assessment regulations for various utilities and transportation properties. The bill seeks to clarify and expand the scope of properties that are centrally assessed, which includes railroad transportation properties, telecommunication lines, and natural gas transmission pipelines, among others.

Key provisions of Senate Bill 540 include amendments to Section 15-23-101 of the Montana Code Annotated (MCA), which outlines the types of properties subject to central assessment by the state. The bill specifies that properties operated across multiple counties or states, such as electric power transmission lines and common carrier pipelines, will be centrally assessed to ensure equitable taxation. Notably, the bill also addresses potential future taxation of properties owned by federally created agencies for energy transmission, contingent upon congressional legislation.

Debate surrounding Senate Bill 540 has centered on its implications for utility companies and the potential economic impact on consumers. Proponents argue that the bill will create a fairer tax structure that holds large corporations accountable, while opponents express concerns about the potential for increased costs to be passed on to consumers. Amendments to the bill have been proposed to address these concerns, but discussions remain ongoing.

The economic implications of Senate Bill 540 are significant, as it could alter the financial landscape for utility companies operating in Montana. By expanding the definition of centrally assessed properties, the bill may lead to increased revenue for the state, which could be allocated to public services. However, the potential for higher operational costs for utility companies raises questions about the long-term effects on consumer prices and service availability.

As the legislative process continues, stakeholders are closely monitoring the bill's progress. Experts suggest that if passed, Senate Bill 540 could set a precedent for how utility properties are taxed in Montana, potentially influencing similar legislation in other states. The outcome of this bill will likely have lasting effects on both the state's economy and its regulatory framework for utility services.
