TP has been a sole proprietor for a number of years, has a qualified plan (Solo 401(k) established, and before establishing the plan obtained an EIN to identify the plan. The TP is also the plan administrator.
TP is converting his business from a sole proprietorship to an LLC in California, and wishes to carry over the retirement plan to the new entity. Should he obtain a new EIN to identify the LLC, or simply use the same EIN he's had all along for the plan? (The latter seems logical to me.)
Are there any other subtleties to this situation?
