  1. What are attachments?

    Attachments are additional information/documents the Wisconsin Department of Revenue (DOR) may request when you file your Manufacturing Forms (M-Forms).

  2. Do I need an attachment?

    When you electronically file (e-file), you include an attachment only for certain schedules and/or questions, which need additional information (ex: appraisal, sketch, asset listing or other document).

  3. How do I make additional information/documents ready to use as an attachment?

    • Electronic documents — save the document in one of the following acceptable file formats: PDF, TIF, JPG, BMP, Microsoft Word or Excel
    • For non-electronic documents — create an electronic file by scanning the document, then save the scanned document in one of these accepted formats: PDF, TIF, JPG, BMP, Microsoft Word or Excel

  4. How do I attach additional information/documents when I e-file?

    1. — in the navigation pane, click the "paperclip"
    2. — then click the "Add a new attachment"
    3. Locate your document in the "Add Files" window that appears
    4. Double click the file you would like to attach
    5. If you successfully attached the file, it appears within the attachment pane
    6. Repeat this process if you have more than one document to attach

  5. Is there a size limit for an attachment?

    Yes. DOR cannot receive more than 16 MB of data attached to a single e-filed return.
    • 16MB maximum is the total combined size for all attachments
    • Large attachments can take a long time to electronically submit and can be disrupted
    • If a disruption happens and you do not get your confirmation number, you must resubmit your return

    Note: It is best to attach a PDF file format since it is generally a smaller size.

  6. My attachment is too large to send electronically. Can I still e-file?

    Yes. Remove the attachment from your M-Form and submit the return without the attachment. After you electronically file your M-Form, submit your documents by email, fax or mail to the Manufacturing & Utility Bureau District Office in your area.
