To: Manufacturers, Manufacturing Property Owners, and Preparers Filing M-Forms

The Wisconsin Department of Revenue (DOR) has opened its electronic (e-filing) system to manufacturers required to file 2017 Manufacturing Personal Property (M-P) and Real Estate (M-R) Returns (M-Forms).  Companies leasing personal property to state-assessed manufacturers should file the Leased, Rented or Loaned Personal Property (M-L) Return. Visit the Manufacturing landing page on the DOR website for more information on 2017 M-Forms.

Note:  Disregard this reminder if you already filed your 2017 M-Form

Notes for 2017:

• Federal Government (IRS) safe harbor and de minimis safe harbor standards that provide guidance for federal income tax deductions do not apply to Wisconsin state personal property tax reporting. Review the 2017 M-P Form Instruction Booklet (page 5) for more information.
• Internet browser bookmarks/favorites to the Manufacturing Assessment System (MAS) from prior years will not work in 2017 due to changes in DOR's web design.  Enter MAS through our website and save a new bookmark.
