The per-participant flat premium rate for plan years beginning in 2014 is $49 for single-employer plans, up from a 2013 rate of $42. The per-participant rate for multiemployer plans will not change over the current year’s $12 rate.
Premium rates are adjusted annually based on changes in the national average wage index, as prescribed by the Moving Ahead for Progress in the 21st Century Act (MAP-21).
For plan years beginning in 2014, the variable-rate premium for single-employer plans is $14 per $1,000 of unfunded vested benefits (UVBs), up from a 2013 rate of $9.
The $5 increase is the result of indexing and a scheduled $4 increase provided in MAP-21. The variable-rate premium is capped at $412 times the number of participants—up from a 2013 cap of $400.
Plans sponsored by small employers—generally fewer than 25 employees—may be subject to an even lower cap. Multiemployer plans do not pay a variable-rate premium.
