Open Book and Board of Review Information

April 5, 2019

To: Municipal Clerks, Treasurers, County Listers, Clerks, Treasurers and Assessors


The Wisconsin Department of Revenue (DOR) is providing Open Book and Board of Review (BOR) information.


Start Date – 7 Day Interim

State law (sec. 70.47(1), Wis. Stats.) requires the BOR to meet annually during a 45-day period, starting the fourth Monday of April; no sooner than seven days after the last day the assessment roll is open for examination, under sec. 70.45, Wis. Stats.

  • Example: an Open Book occurs on a Tuesday. The earliest the BOR can be scheduled is the following Tuesday.
  • During this seven-day period, an assessor can elect not to sign the affidavit and continue to make changes and sign the affidavit on the day of the BOR's first meeting. Alternately, the assessor can elect to sign the affidavit immediately after the Open Book meeting and make no changes during the seven-day period before the BOR begins.
