"An employer maintains a safe harbor 401(k) plan that provides for a safe harbor matching contribution of 100% of elective deferrals that do not exceed 4% of compensation. Since the plan's inception several years ago, the employer has inadvertently provided a match of 100% of elective deferrals up to only 3% of compensation. So, each year, anyone deferring more than 3% has missed out on a matching contribution on 1% of
compensation.
"EPCRS doesn't specifically address this failure, but it seems that the logical way to correct is to make a contribution of the 1% match, plus earnings, to all affected participants for all affected years. In describing the allowable correction methods, Appendix A of Rev. Proc. 2021-30 provides that, if in addition to a failure to make a contribution, a 401(k) plan also failed the ADP test or ACP test, the
correction methods under Appendix A cannot be used until after correction of the ADP or ACP test failures.
"In this case, although this is intended to be a safe harbor plan, the employer failed to make the required safe harbor contribution for some participants. So, technically, the plan was not operated as a safe harbor plan in those years. Does this mean that the employer is required to run the ADP/ACP tests for all of those
years, correct any failures of ADP/ACP, and then correct the failure to make the matching contribution? It seems to me that by simply making the corrective contribution of the missing 1% match (plus earnings) to all affected participants, the plan will be restored to safe harbor status for all years, making the ADP/ACP tests inapplicable, so it shouldn't be necessary to run the ADP/ACP tests for all affected years. I would appreciate all
input!"
