<prompt> Human: I changed job classifications at work last year. Employer was not initially making match contributions as stated in employment contract. After having alerted them to their error, they started making catch-up contributions to make up for it. They mistakenly continued to make these catch-up contributions for a much longer time frame than they should have. I noticed after 3 weeks that they still being placed into my account. Knowing that these were in error, I contacted my benefits department and was assured that all contributions were correct and that these catch-up contributions would continue until I was fully compensated. Fast forward to this April. I receive my plan statement and notice that there was a withdrawal of 5400 in March. I call my the company that services my 401k and they say it was a requested withdrawal from my employer. After getting a hold of my benefits office, they explained that they had made a mistake. I reminded them that I had brought up the mistake in the first place but was ignored. The person I talked to denied previously having been contacted by me in regards to the issue. I dont expect to see the return of funds, but Im less than pleased that they would find it acceptable to take any actions regarding my accounts without any communication. Am I silly in thinking that they should have to communicate any sort of errors made in regards to contributions? Should they have sent anything in writing stating that they were going to rectify their mistakes?  <response>: Wow, all sort of compounded errors going on here. You should have them contact the Employee Plans Compliance Resolution System Just clawing back the excess deferral out of your account is definitely unacceptable. But the way they were trying to compensate you for the missed deferrals was wrong in the first place: They are at risk of having their plan disqualified entirely if they dont complete the voluntary resolution process and put together a plan for avoiding such mistakes in the future.
