Revaluation of Properties in 2024

12/15/2023; The latest information is that the new assessment value notices to all property owners will be mailed in late summer/early fall of 2024 with new assessment values. This timeline is subject to change if necessary.

Our town assessor prefers to wait until the State’s 2024 equalized value numbers are known, which is typically in early August. After that point, the last part is to finish and complete the entry of assessments, and the notices will be prepared and mailed. Instructions on the process will be included in the mailed notice along with dates for Open Book and Board of Review.

A guide to property owners is available now on the State’s website at https://www.revenue.wi.gov/Pages/Municipalities/bor-calendar.aspx.

To be notified of any changes, we recommend subscribing to News & Notices on our website. Notice alerts will be sent to you by your preference; email and/or text message.

Final assessment notices will be mailed to the same address as to where the tax bills are mailed. If your mailing address is wrong/incorrect on your tax bill, please do the following:
