Manufacturing omitted property assessment rolls and correction of error assessment rolls are produced at the same time as a municipality's 2023 equated manufacturing assessment roll. To determine whether a municipality's manufacturing assessments are finalized for 2023 property tax rolls, review the Equated Rolls Status Report. The Wisconsin Department of Revenue (DOR) periodically updates the status report and list of omitted property and corrections or errors in October until all municipalities are equated. Municipalities cannot be equated until they have successfully filed their 2023 Final Statement of Assessment (SOA).
The files below include manufacturing (MFG) assessment rolls produced to date for municipalities with:
- Omitted manufacturing real estate and/or personal property discovered and assessed during 2023 (omitted during 2018-2022)
- Correction of errors by assessors - palpable errors made in 2022, discovered and corrected in 2023
Manufacturing Assessment Rolls to Date:
Information for municipal clerks on omitted property assessments and correction of errors by assessors is located in DOR publication PA502 - Assessment and Tax Roll Instructions for Clerks.
Manufacturing Omitted Property Assessment Rolls
Manufacturing omitted property rolls contain assessments for any manufacturing property discovered that was omitted from any of the five prior year manufacturing assessment rolls. When omitted property is discovered, DOR notifies municipalities and manufacturing property owners by mailing an omitted manufacturing property assessment notice. If your municipality received a notice of omitted manufacturing property during 2023, locate the associated omitted property roll(s) on this web page, download, print a copy for your records, and calculate the omitted property tax due.
Refer to the Omitted Property Interest Calculation Information Sheet for instructions on calculating omitted property taxes and interest.
Manufacturing omitted property rolls contain:
- Year of omission - limited to the five prior assessment years
- Aggregate assessment ratio of municipality for year of omission - local level of assessment
- School district code
- Manufacturing property owner name and mailing address
