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