5 Flat-rate Premium
(1) Applicable rate – Enter the per-participant flat premium rate. For 2016, the rate is $64 for Single‑employer Plans and $27 for Multiemployer Plans.
(2) Participant count – Report the number of participants covered by the plan on the Participant Count Date separately for active participants, terminated vested participants, retirees and beneficiaries receiving payment, and in total. See "How to Count Participants" section.
(3) Flat-rate Premium – Report the product of the Participant Count and the applicable premium rate. If the plan year is a short plan year, the required Flat-rate Premium may be a prorated portion of this amount; however, the amount reported in this item must reflect a full year’s premium.
Note that you must make a premium filing even if the Flat-rate Premium is $0. This may happen, for example, if your plan is a New Plan that grants no past service credits, so that there are no Benefit Liabilities on the Participant Count Date. A plan with no Benefit Liabilities has no participants for premium purposes.
