The Wisconsin Department of Revenue (DOR) would like to remind state-assessed manufacturing property owners of the upcoming extended deadline for filing 2020 Manufacturing Property Returns (M-Forms).

If you requested a filing extension on or before March 2, 2020, your M-Form(s) you must file by Monday, April 1, 2020, to avoid late filing penalties.

April 1 – Extended Filing Deadline (2020 Forms M-L, M-P, M-R)

  • Form M-P (PA-750 P) – Manufacturing Personal Property Return
  • Form M-R (PA-750 R) – Manufacturing Real Estate Return
  • Form M-L (PA-750 L) – Leased, Rented, or Loaned Personal Property Return

All M-Forms must be e-filed or mailed to the Manufacturing & Utility Bureau District Office responsible for the location of your manufacturing property by April 1, 2020.

  • If you mail your M-Form, it must be postmarked on or before April 1, 2020, to be considered timely

See our website for information on how to download and electronically file (e-file) these forms.

Late Filing Penalty

If you do not file your M-Form or file it late, you will receive a non-filing penalty and lose the right to appeal your assessment. See Late filing penalty.
