About the Big Sandy Property Market
Big Sandy is a city located in Chouteau County, Montana. Every property inside the Big Sandy city limits is assessed by the Chouteau County assessor, which applies Montana property tax rules uniformly across the county.
Because Big Sandy property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Big Sandy home is over-assessed have the right to file a appeal directly with Chouteau County.
Montana allows the assessor to defend or adjust the assessed value during a appeal, so Big Sandy homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Big Sandy Property Market Context
As a city in Montana, Big Sandy inherits the state's assessment framework — which shapes how over-valuations occur and how homeowners can fight them.
Montana market character
Montana reassesses on a two-year cycle, and the state saw historic 40%+ appreciation in the 2023 cycle that produced widespread sticker-shock notices. Bozeman, Missoula, and resort areas have been the epicenter of over-assessments.
How Montana handles appeals
Montana homeowners file an informal review (AB-26) with the Department of Revenue, then appeal to the County Tax Appeal Board, then the Montana Tax Appeal Board. The state is responsive to comparable sales evidence.
When to file in Big Sandy
AB-26 must be filed within 30 days of receiving the assessment notice — typically July or August depending on county.
