Has anyone found a quick and reliable tool in ProSeries to determine whether MFJ or MFS is optimal, and how to split the returns with minimal additional work?  I use the T, S, J coding on every entry I make.  When I use the MFJ vs MFS worksheet, the information it provides frequently turns out to be incorrect or inaccurate when I actually split the returns and do all the re-work of the separate returns.  Any suggestions?  The additional required analysis can be a significant time burner.  Thank you!
