Filing M-Forms late – after April 1 extended deadline

Under state law, all manufacturers with a filing extension must file the 2022 Manufacturing Property Return (M-Form) by April 1, 2022.


Electronically file (e-file) your M-Form

DOR recommends e-filing your 2022 M-Forms through our Manufacturing Assessment System (MAS). M-Forms can still be e-filed after the April 1, 2022, extended due date. The MAS system automatically time stamps returns when the preparer designates the form as complete. Penalties are assessed based on the e-file date.
