Partner A owns 50% of Firm 1 and 100% of Firm 2. Partner B owns 50% of Firm 1 and 100% of Firm 3. Business is wealth management service and all 3 firms are S-Corps. Firm 1 is support staff and expenses, while firms 2 and 3 are the respective partners. Does this represent an Affiliated Service Group? I note that the partners are both licensed. Finally piece of the puzzle is that the one support staff working for Firm 1 is a leased employee, where the leasing firm provides a 401(k) plan with a 100% of 1st 4% Safe Harbor Match. That Match is paid by Firm 1 (indirectly paid by Firms 1 & 2). Is there a coverage issue if Firm 2 and Firm 3 have SEP's that only cover the respective partners? If firm 2 replaced its SEP with 401(k) covering only Partner A would that cause a problem?
