<prompt> Human: Hi, Im about to switch jobs, going from one job where I max out my 401k to another job where I max out my 401k. When I leave, where should I roll over my 401ks? To an IRA? What is best?Thanks in advance for your advice!  <response>: Unless your new jobs 401k is _fantastic_, roll it to a _traditionalrollover_ not Roth IRA. If you dont already have one, call Vanguard and have them walk you through the process.Some tips: You probably want to maintain your asset allocation among all of your retirement accounts; in this sense, your IRAs including a Roth, if you have one can be used to make up for problems in your new 401k. Wait for your last 401k contribution to hit the account before doing the rollover Do not cash it out. Similarly, now is probably not the time for a Roth conversion. Recall that the 401k maximum is per year, not per job. So you dont have a fresh 17,500 of space to add just because your employer changed.
