The Wisconsin Department of Revenue (DOR) would like to remind you that the 2019 filing deadline for the Municipal Assessment Report (MAR) is next Monday, June 10, 2019.

  • Electronically file (e-file) the MAR by midnight Monday, June 10, 2019

MAR Non-filer lists

  • Attached is a summary of the MAR reports that have not been filed
    • Report includes non-filers as of 11:00 a.m. today, Monday, June 3, 2019
  • Review the non-filer list to make sure we received your filing
  • DOR will email updated non-filer summary on Monday, June 10

Non-filed or late-filed forms

If you do not file by Monday, June 10, 2019, the following may occur:

  1. Municipal reporting – municipality receives a reduced levy limit due to the lack of new construction information
  2. TID reporting – prior year's non-manufacturing full value is certified for the current year. This may result in less tax increment dollars available to the municipality.
    Note: If you do not file a MAR by June 10, 2019, DOR's Equalization Bureau will file a formal complaint against your certification with the Office of Technology & Assessment Services, requesting a review and possible revocation of your assessor certification under state law (sec. 73.09(7), Wis. Stats.)

If you have questions, contact the Equalization Bureau District Office in your area.
