Kathryn, Aatrix was reporting a problem with the Medicare limit, which was not correct. I then found article 23686 on the KB which confused me even further. In the end the problem was they had the 2014 FICA limit of $117000 in the Sage tax table for 2015 instead of $118500. This required changing the database to move the FICA withholding from income tax to FICA for the one employee, then re-doing the 941 to pay an additional $93 in employer taxes.
