if m1w line 1doesn't work

[mlundberg123456]

why does line 1 on form m1w say the number is wrong

Edit your W2 and look for :

• MN tax id is 7 digits
• MN state is chosen
• MN wages filled in
• MN tax withheld has a number
• or all lines blank - it is either all filled or all blank for the state boxes
• wages must be greater than taxes paid

If you need extra time, filing an extension by April 15, 2026, moves your submission deadline to October 15. But remember any taxes owed are still due in full by the original April 15 date.  Pay through either Direct Pay or your individual online account. See if you need to file a state extension.
