From Legal Challenge Targets Montana's New Property Tax System

How could the legal challenge to property tax legislation affect Gallatin County?

Possible What happens if… A possibility worth considering, not a forecast.

State property tax lawsuit may alter local revenue streams for Gallatin County A lawsuit is challenging the structure and passage of Senate Bill 542 and House Bill 231, which completely reshaped Montana's property tax rates. These bills introduced graduated tax rates and homestead rates, which determine how property taxes are calculated statewide. If the court finds the structure of these bills unconstitutional, the entire tax framework could be invalidated or forced to change, which would directly impact the property tax revenue collected by local entities, including Gallatin County. The county's funding structure relies on these state-mandated rates and classifications.

  • The bills created graduated tax rates and homestead rates starting in 2026.ktvq.com

Why it matters

Local governments like Gallatin County rely heavily on property tax revenue to fund essential services and operations. Since the state's property tax system is being legally challenged, any change in the tax structure—such as the invalidation of rates or the alteration of homestead classifications—could directly affect the county's expected funding and revenue streams.

This challenge is part of a larger effort to redefine how property taxes are applied across Montana. The state's Governor's office noted that the reform led to tax cuts for 80% of Montana homes, but also mentioned the rollback of about $95 million in property tax rebates claimed last year, indicating the significant financial scope of the reform.

What we don't know yet

  • Will the district judge rule in favor of the plaintiffs or the state regarding the constitutional challenges?
  • If the tax structure is altered, what specific new rates or classifications will be implemented?
