C. B., thank you very much for presenting Derrin's explanation and your comments. Being a both a leased employee and an independent contractor has spurred additional thoughts and is quite helpful. You wrote "Edit: HCE ownership does not apply for A-orgs". I did not understand this comment as the EOB states "The A-organization must have an ownership interest in the FSO." I saw no exception for HCE's. A law firm is used in the first example and says "Each corporation has a one-third partnership interest in the law firm". Thus the ownership interest is emphasized.
I have ruled out them being in an A-Org or B-Org as there is no common ownership For a few years, I have been thinking each these CPA non-equity partners are leased employees from their own P.A. The only thing that has me doubting leased employee status is this from my original post:
"Regarding a Leased Employee and the control test, the EOB states "On the other hand, professionals who regularly make use of their own judgment and discretion on matters of importance in the performance of their services and are guided by professional, legal or industry standards, generally do not satisfy this test."
However, in my 3rd post I wrote "When they became non-equity partners, they became employees of their own P.A. Their roles largely stayed the same." I wrote, per EOB, they "are guided by professional, legal or industry standards, [means they ] generally do not satisfy this test" [of being a leased employee]. Since they are performing basically the same role as when they were a "common-law employee" when employed by the CPA firm, I don't see how being "guided by professional, legal or industry standards" now suddenly disqualifies them from being a leased employee. I think they are either "leased employees" or part of an ASG "management group". I am leaning toward thinking they are each a "leased employee".
