In the past few years we have filed a greater number of MFS and RDP returns using form 8958 to properly show the community property split. (We are in California.)
In the past most of these returns have gone through smoothly (it took a year or two for the RDP same sex marriage returns to be processed properly).
In the current tax season we have had at least 8 returns get held up, many still waiting "review".
I have tired calling the hotline in each case. Occasionally the representative has been able to straighten the problem out. For most of the returns however we were orginally told to wait 60 days, and for many of those we have now been told to wait another 60 days.
Some of my clients have received notice requesting copies of W-2's or even identity proof.
I have had a few hotline representatives acknowledge that it is a system - wide problem resulting from new security procedures.
FYI and UGH.
