SEP + Profit Sharing or Cash Balance

Good morning!  I have a new client that is currently maxing out a SEP, but also has the opportunity to start a Profit Sharing or Cash Balance Plan.  I don't believe the SEP has any bearing on the maximum contribution into the other plans, as the companies are unrelated, but I wanted to make sure someone could max out both a SEP and a Profit Sharing (or receive a contribution in a Cash Balance).

Thanks in advance!

Your belief is incorrect. 

EDIT - when I wrote the above I had missed the "unrelated" part.  CBZ is correct if truly unrelated for CG, ASG and 415(h) purposes then yes the participant could do this.

Depends how "unrelated" they are. Even if there is not enough common ownership to create a controlled group under 414(b)-(c), there might still be a controlled group under 415(h).

TBH I missed that "unrelated" part.  Problem with old eyes reading a forum message on a mobile device early in the morning.  So if they are truly unrelated, then yes one person could participate in a one company's SEP and the other unrelated company's qualified plan(s).   I will edit my other reply to note this.  Thanks.
