Open Book & Assessment Appeals

Assessment Notices

Assessment notices will be mailed April 16. Assessments for 2021 will be available on our webpage by April 19.

Open Book Period

The Open Book period is an opportunity to discuss the value of your property. Our appraisal staff is available to explain the methodology and facts used to determine the assessed value shown on the Assessment Notice. This period is particularly important for property owners who believe the market value of their property differs from the assessed value and have information to share with the appraisal staff.

The 2021 Open Book Period is April 19 – 30.

Property owners must contact the appraiser for their property in one of two ways:

Support staff fielding the initial contact will direct you to the appropriate appraiser and provide information about our process and resources. The appraiser will then contact you based on the initial information provided.

Next Steps

  1. File an Objection

    At the conclusion of open book, if your opinion of value still differs from our assessment, you may file a formal written objection. This must be filed by May 7, 2021 at 4:30 pm. Please contact our office at 608-266-4531 or for access to the objection form. Please note that providing your opinion of market value is required.

  2. Board of Assessors

    Per Wis. Stat. § 70.075, all objections to valuations filed are reviewed and processed by the Board of Assessors. Assessments in the City are established through mass appraisal. The objection process triggers an individual appraisal of that property with the Board of Assessors. To that end, the Board reviews making all necessary corrections to arrive at market value.

    The Board of Assessors meets weekly throughout summer and early fall to review the hundreds of objections filed in a City with 90,000 parcels.

  3. Board of Review

    If you disagree with the determination of the Board of Assessors, the final municipal review of assessments is the Board of Review. The Board of Review is a quasi-judicial body comprised of appointed City residents who hear the cases and make final determinations on value. The Board of Review meets as needed throughout mid-summer and early fall.

Additional Filing Requirements for Commercial Properties

Commercial properties must also provide income and expense information. This information must be submitted with the Objection Form.

All residential rental properties must complete a gross rent statement and provide it with the Objection Form.

If an agent is representing the property owner, an agent authorization form is required.


What if the May 7th deadline was missed?

You must file a completed Objection Form with the City Assessor's Office prior to or within the first two hours of the first meeting of the Board of Review. The Board's first scheduled meeting is Monday, May 10, 2021 at 4:30 pm. Incomplete objections cannot be accepted.
