Then why are other software companies allowing it?  I'm sorry but is it mandatory by the state?  I don't think so.  I think a better idea would be if you choose paper copy return then block it from being printed.  However, if you choose e-file there is no reason to block it.  No one who is e-filing is mailing anything in.  That makes more sense to me.  It would be one thing if the forms weren't delayed but they are.  This tax season is tough enough on all of us tax preparers as it is.  Isn't our software company suppose to help us with our tax season?  Isn't that why we pay the big bucks for our program?  I have had 5 clients come in and at least 40-50 more before the Illinois release date of 2/7.  I am not able to give them a copy of their Illinois tax return using the Lacerte program.   Huge burden on my firm this year and last year.
