You do not add a cash balance 401k into an annuity based pension plan. That is correct.
What is the penalty for having two retirement accounts?
I had 6, then 5, then 6 again, now 5.
You either leave the 401k where it is, or roll it over into an IRA at a brokerage firm.
Just rollover your 401k to an IRA at a mutual fund company. There is no penalty for having an IRA plus a pension. In fact, it is a wise move to have both (not all your eggs in one basket).
There's no penalty for having an old 401K and a new pension.
There is no "penalty" for having two retirement accounts. When one leaves a job with a 401(k), the obvious action is a direct rollover into an IRA.
A $401,000 salary is prett significant. I wouldn't think you even need to worry about pension or possibly even a job depending on how long you were at the last job.
Toll it into an IRA.
