The Cass County Assessor's Office will be conducting our required 6 year review (reappraisal) in 2024 for the 2025 values. Data Collector's will be in the following areas from April through Dec 31, 2024:

Towns Rural Townships
Plattsmouth City On the Green Subdivision

Data Collector's can be identified by their orange reflective vests and county-issued badges from the Sheriff's Office. They will be taking photos and measuring structures on the property. If no one is home to verify property data at the time of the visit, a call-back slip will be left on the door.

Owners can find the property review questionnaire below. These questionnaires can be mailed to the Assessor's Office or put in the drop-box on the west side of the courthouse.

In addition to reappraisal, Data Collector's will be doing sale reviews and permit/pickup work throughout the county. If you have questions please call the Assessor's Office at 402-296-9310.
