<prompt> Human: I will admit, I am woefully uninformed about how to properly manage my 401K, so any ELI5 answers are appreciated. We received a message from our HR team telling us that if we want to lower our contribution for the week we receive our bonuses, we need to do it by a certain date. What is the advantages or disadvantages of this? I do have a contribution match, of which I am at the top amount percentage-wise. Not sure what else I need to consider when evaluating if this is worth doing.Thanks very much.  <response>: If you want your bonus in hand rather than in your 401k, or if you have your contributions set to max out for the year, not counting the bonus.
