Hello, my client has an SCorp with solo 401k that has traditional and Roth IRAs. She took the max based on her age & salary - $30k pre-tax EE contribution and $30k ER contribution.

1) If EE $30k went to the traditional 401k can the ER $30k portion be placed in the ROTH?

2) If yes, would the ROTH ER contribution be deductible to the SCorp?

Thanks in advance for your help!
