@brilliantusa I am confused as to your entity ownership. What I get is
(a) You have a partnership / multi-member LLC
(b) Some of the members themselves also have sole proprietor business.
(c) Are you saying g that these sole proprietorships ( dis-regarded entities ) entities are members OR the sole-proprietor owners ( persons ) are members ?
(d) Partnerships themselves ( at entity level) obviously can be natural person or fictitious person.
(e) my sense of your entity is a partnership of persons with SSN but obviously there should be no issue having an EIN if the member does business as an entity -- if TubroTax gives you trouble you can always enter the EIN in the SSN format. For tax purposes though a single member LLC is disregarded entity and files schedule-C with owner SSN
Does this make sense ?
