The Big Stone County Assessor's Department is responsible for the equalization of property assessments throughout Big Stone County. It is the Assessor's responsibility to ensure each property is equally and uniformly assessed. To do this, the Department estimates a property's market value and classifies it according to its use for property tax purposes.

By law, every parcel in the county must be viewed by an assessor at least once every five years. In addition, every year assessors visit any parcel with new construction, alterations, or improvements.
