MFJ to MFS
Can someone with experience provide information on what the process is to amend a MFJ to MFS. 2021 return was filed as MFJ. There is a benefit if it were filed as MFS. IS a 1040x involved? How do you then file the separate returns? I am using ProSeries Pro. Appreciate any information you can provide.
While researching the topic, I thought I read a return filed as MFJ CANNOT be changed to MFS after the due date. Is that correct?
