There are no maximum amounts for rollovers. The rollover is not considered part of your annual contributions. You could rollover your 401k and still contribute another $5,500.

Roll overs don't count toward the maximum. The maximum is based on new deposits.

I want to roll my 401k into a Traditional IRA. The most you can contribute to a Traditional IRA is $5500 a year. How can I roll my 401k into a traditional IRA if I have more than $5500 in my 401K?
