We had a new earnings code used for group of associates on our last payroll that was not setup correctly as 401k eligible. It was caught after 1 payroll and will be corrected on the subsequent run. So while everyone who elected a deferral had their deferral calculate on part of their earnings, there were some whose contribution did not calculate on all of their earnings due to this code. For example, base salary $500, new commission code $100, 10% deferral should have been on $600, but we took on $500.00
Proposed correction method is letting everyone who was affected know that they can increase their deferral to make up for any part on their end, and let our match true up catch anyone who missed a match contribution. (safe harbor plan, match contributions every payroll with true up at year end)
Comments? We at first thought we had to do QNEC on match, however, would get double match at true up time.
