income for solo401k passive income

[Glenn N.]

I would like  to start a solo401k, I had someone draw up a structure. This structure would be A C-Corp holding company with two hard money lending LLCs ( passive income disregarded entity) paying the C-corp fees to run them. Then the C-corp would open a Solo 401K for me and fund it with the fees. One lawyer said it was completely legit, But I want to fund the whole 401k, and to do that it be income off almost 200K and how would I justify these using fees? I had another lawyer say you cannot fund this with passive income from the two LLCs with passive income. I would have had the two LLCs 'c that was lending but I had to retract the s status because you cannot have more than 3 years of passive income in an s-corp . Seems like it would be pushing the envelope and asking for an audit and fines.
