<prompt> Human: So in a less then a month, Im starting a new job. Only issue is, because of a lot of circumstances, its going to overlap my current job by a week. Completing the work is no issue and there is no risk.My only question is regarding 401ks: I currently participate in a 401k with current employer, and have already signed up for 401k with future provider. Is there any legal issue of those two plans overlapping for the week? Not really sure why it would but, you never know. Guess I could see matching being an issue somehow.edit: I wont overcontribute. Ive got that set figured out to max on time despite this.  <response>: Theres no harm in having two 401Ks. The only thing to be wary of is if you contribute the max amount, 17500year, you may go slightly overboard this year by one weeks worth, and its a pain to correct. If you dont contribute that much per year, theres 0 worries
