Ordinarily, none of my clients would be eligible for the EITC.  It just happened because of this particular change and a lower income year for this client. (who is a good test case for the software due to the number of forms associated with the client's return).

With respect to CPE, this issue was not covered in my "individual tax update" CPE provided by my state society.  I sent a note to the CPE provider, as others might miss this change too.
