<prompt> Human: I maxed my 401k at an old employer no match, and my new employer has a generous match 10k for maxing. I know that my new company will have no knowledge of how much I contributed at my old company, but what happens when I have twice the allowed limit contributed at the end of the year? Do I have to pay a fee? How are the funds removed from the 401ks, and which 401k would they be removed from?  <response>: You should be able to contribute to the new 401k and request a refund for the overcontribution to the old one at the end of the year: Id call your brokerage to confirm that this will work before doing it.
