When you have a wrap document covering a health (plan 6/1/2017 to 5/31/2018) and a separate dental plan (11/1/2017 to 10/31/18), where each benefit has a different contract date and the Form 5500 is due 7 months after the plan year end, which date do you use to figure out the PYE of the required 5500 (over 100 utilizing the benefit) and when the 5500 has to be filed? Thanks for any replies.
