Assessor

Assessor

The Assessor is charged with several administrative and statutory duties. The primary duty and responsibility is to value & classify all real property within the Assessor's jurisdiction except that which is otherwise provided by law. This would include residential, commercial, industrial, and agricultural classes of property.

Fall 2025 Property Review (for the 2026 Assessment)

Any permitted work in the urban areas will be reviewed for completion.  Rural properties will be reviewed to observe any recent changes that may have occurred.  Typically there will be two staff members taking notes, reviewing plot plans & taking pictures. They will be driving a 2016 Ford F-150 Gray Crew Cab with stickers on the doors identifying them as the Winnebago County Assessor’s office.  

If needed, we may mail out forms asking for more information for any new construction or demolition that has occured.  Please feel free to call the Assessor’s office to notify us of any changes to your property or fill out the online data correction form found on the parcel report page on the Beacon website. 

Property data for each property can be viewed by clicking on the blue Property Search (Beacon) button above. 

Any updates/changes made will be reflected in the 2026 assessment.  If there are any changes from the 2025 assessment values, property owners will receive notification of these changes by mail postmarked by April 1, 2026.

Thank you in advance for your cooperation!
