For 2020, a Participant elected $1,625.00 401k plus 541.66 catch-up withheld per pay.
December 29, 2020, Participant completed another election form electing $19,500 annual 401k plus $6,500 annual catch-up withheld (proportionately from each pay). The employer provides 24 payrolls per year, therefore the 2021 per pay withholding should change to $812.50 + $270.83 respectively. Unfortunately, it was not changed and for both of January 2021's payrolls the previous election stood.
Both of January 2021's 401k deferrals have been remitted over to the plan (same day as pay dates) making this not only a payroll issue but a plan correction issue.
How best is this corrected? Should the employee be provided a special paycheck equal to the over contributions with taxes withheld (recognizing FICA will be overpaid)? And then to correct the Plan, should the contributions to the Participant's account be removed and placed in a forfeiture account?
The employer realized the error and spoke with the Participant who is okay with what happened, does not want a correction, and simply wants to skip 401k deferrals for the month of Feb and restart again in March (plan does permit this frequency for changes) - is this acceptable?
Thank you.
