Retirement tax questions

I see on IRS website, it states if the excess deferrals aren't withdrawn by April 15, each affected plan of the employer is subject to disqualification and would need to go through EPCRS. Would this be another concern for this scenario? 


It's an issue if the plan made errors.  This could impact you directly if you have a solo 401k, and you contributed too much, because in that case you are also the plan manager.  But in the normal situation with a W-2 employee, the plan almost always follows the rules and if the employee ends up with excess deferrals, it's because the employee had 2 jobs.  If the plan really did make errors, that's an issue between the IRS, the plan, and the employer.
