Thanks for the answer. Agreed on the first and third points.
On second point, I understand substantially different activities require different schedule Cs, but do I actually have to have different LLCs and solo 401k plans as well? The original business is general consulting services for a specific industry (manufaturing), the new income would still be general consulting but for services (SAAS/IT). Overall the work is quite similar (investment analysis, spreadsheets, etc.), just different industries.
Right now I have income "A" going into Schedule C "A" from LLC "A" into 401k "A". Can the extra income "B" going into schedule C "B" (or still "A" since close enough?) still roll up to LLC "A" into solo 401k "A"? Hope this makes sense. Thanks!
