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