FAQ - ANSWER
I have a 401k at my current employer, but plan to change jobs. Can I
start a second 401k account at my new employer and still keep the 401k
account at my former employer?
Answer: There are no restrictions on how many 401k accounts you have. As
long as the balance of your existing 401k is over $5,000, you can leave it
at your current employer and start another 401k at your new employer. If the
balance is less than $5,000, the plan sponsor has the option of requiring
you to rollover the assets into an IRA or another 401k.
