I know only a handful of states offer amended tax return e-file compatibility.  I was just curious if anyone knew what the consensus among the other states was regarding adoption of this process?  Are other states moving to accept amended e-filed returns quickly? 

Most of my clients are in a state that does not offer amended return e-file, so the federal amended e-file is only of limited help for me (sure the e-file is nice, but it bifurcates my filing process and confuses the client a bit).  Once more states add this, I can see the real value here.
