About the Gann Valley Property Market
Gann Valley is a city located in Buffalo County, South Dakota. Every property inside the Gann Valley city limits is assessed by the Buffalo County assessor, which applies South Dakota property tax rules uniformly across the county.

South Dakota allows the assessor to defend or adjust the assessed value during a appeal, so Gann Valley homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Gann Valley Property Market Context
Gann Valley sits within South Dakota's broader property tax landscape as a city, and local assessments reflect both state rules and county-level mass appraisal practices.
South Dakota market character
South Dakota has no state income tax, so property taxes carry more weight — effective rates are around 1.1%. The state assesses residential at 85% of market value, and rapid growth in Sioux Falls and Rapid City has created assessment pressure.
How South Dakota handles appeals
South Dakota homeowners appeal to the local Board of Equalization, then the county Board, then the Office of Hearing Examiners. The three-step process is homeowner-friendly.
When to file in Gann Valley
Local board appeals are due by the Thursday before the third Monday in March. Very tight window — file early.
