MT SB534

Extends existing property tax exemptions for fiber optic and coaxial cable to include wireless infrastructure (towers, antennas, radios, transceivers, shelters, and associated equipment) placed in service on or after July 1, 2025

Wireless infrastructure receives a 5-year full property tax exemption, followed by a 5-year phase-out at 20% per year, reaching 100% taxable value after 10 years total

Owners must reinvest tax savings by installing new fiber optic, coaxial cable, or wireless infrastructure in Montana within 2 years of claiming the exemption, without passing costs to consumers

Exemption is subject to termination and recapture (plus interest and penalties) within 10 years if owners fail to meet reinvestment requirements or violate provisions

Department of Revenue must establish a website page for infrastructure owners to notify local governments of planned installations and for local bodies to comment on projects
