Non-filed or Late-filed Forms

If you do not file by Monday, June 10, 2024, 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, 2024, 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.)
