Good questions. The work that your client is asking you to perform is for the previously existing single employer plan for the 2022 short plan year. They (you) will need to file a "Final Form 5500" for that previous plan (with a final audit, if one is required) for 2022 and on that 5500 indicate that the plan was MERGED into the XYZ Pooled Employer Plan. It is almost certainly a plan MERGE, not a TERMINATION, btw. You may be able to reach out to the new TPA on the PEP for clarification. Happy to chat as well.
