(b) Participant count rule for purposes of determining filing due dates. For purposes of determining under paragraph (a) of this section whether a plan has fewer than 500 participants, or 500 or more participants, the plan administrator shall use— (1) For a single-employer plan, the number of participants for whom premiums were payable for the plan year preceding the premium payment year, or (2) For a multiemployer plan, the number of participants determined as of the following date: (i) If the premium payment year is the plan's second plan year, the first day of the first plan year; or (ii) If the premium payment year is the plan's third or a subsequent plan year, the last day of the second preceding plan year. (c) Due dates for new and newly covered plans. Notwithstanding paragraph (a) of this section, the premium form and all premium payments due for the first plan year of coverage of any new plan or newly covered plan shall be filed on or before the latest of— (1) The fifteenth day of the tenth full calendar month that began on or after the later of— (i) The first day of the premium payment year; or (ii) The day on which the plan became effective for benefit accruals for future service; (2) 90 days after the date of the plan's adoption; or (3) 90 days after the date on which the plan became covered by title IV of ERISA. (d) Continuing obligation to file. The obligation to file the form or forms prescribed by this part and to pay any premiums due continues through the plan year in which all plan assets are distributed pursuant to a plan's termination or in which a trustee is appointed under section 4042 of ERISA, whichever occurs earlier. The entire premium computed under this part is due, irrespective of whether the plan is entitled to a refund for a short plan year pursuant to §4006.5(f). (e) Improper filings. Any form not filed in accordance with this part, not filed in accordance with the instructions, not accompanied by the required premium payment, or otherwise incomplete, may, in the discretion of the PBGC, be returned with any payment accompanying the form to the plan administrator, and such payment shall be treated as not having been made.
