The Wisconsin Department of Revenue (DOR), State and Local Finance Division posted the 2024 notification rolls to our website.

Note: DOR no longer mails manufacturing and telecommunication notification rolls to municipalities.

Manufacturing Notification Roll

The manufacturing notification roll identifies all real estate in your municipality currently classified as Manufacturing (Class 3) for assessment purposes as of February 15. DOR will assess the properties in the notification roll in 2024.


  • New manufacturers must contact us by July 1, 2024, for manufacturing classification approval for assessment year 2024 for business activity.
  • DOR may add or remove parcels and businesses until it finalizes the assessment roll
  • 2024 assessment rolls are available in three formats:
    • Adobe PDF – by county
    • Data file – comma separated values (CSV)
    • Web view – HTML
