About the Mosby Property Market
Mosby is a city located in Garfield County, Montana. Every property inside the Mosby city limits is assessed by the Garfield County assessor, which applies Montana property tax rules uniformly across the county.
Because Mosby property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Mosby home is over-assessed have the right to file a appeal directly with Garfield County.
Montana allows the assessor to defend or adjust the assessed value during a appeal, so Mosby homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Mosby Property Market Context
Every Mosby homeowner operates under Montana property tax law, and understanding the state context is the first step toward a successful challenge.
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 Mosby
AB-26 must be filed within 30 days of receiving the assessment notice — typically July or August depending on county.
