I am in this forum on a daily basis, and see all of the tax
questions that come through this board. But no one in this forum has posted anything about a similar issue, and none of my personal clients have come to me with a similar issue.
As I am sure you know, typically when the IRS makes an adjustment on a taxpayer's return, they will also receive a notice that explains why the adjustment was made, so I am surprised that your clients apparently did not also get an explanation for this adjustment.
Obviously there is not much I can suggest to you at this point other than calling the IRS for an explanation. If they simply keep the money and it ends up being a refund that was issued in error, then they will not only have to pay back the money, but would also owe interest. So it would be better for them to find out now if this is really money they get to keep and what the reason was for the adjustment.
Maybe this helps partially explain why we have a trillion dollar deficit!

Thank you cpatx, and let me know if you have more questions, although I am not sure what else to suggest at this point.
