About the Great Falls Property Market
Great Falls is a city located in Cascade County, Montana. Every property inside the Great Falls city limits is assessed by the Cascade County assessor, which applies Montana property tax rules uniformly across the county.
Because Great Falls property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Great Falls home is over-assessed have the right to file a appeal directly with Cascade County.
Montana allows the assessor to defend or adjust the assessed value during a appeal, so Great Falls homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Great Falls Property Market Context
Great Falls homeowners navigate the same Montana assessment system as every other community in the state, but local market dynamics mean over-assessments here have their own character.
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 Great Falls
AB-26 must be filed within 30 days of receiving the assessment notice — typically July or August depending on county.
