When you're a contributing employer, the National Pension Plan has you covered. Your negotiated contribution rate pays for all administrative costs of the plan including recordkeeping, audits, legal fees, investment expenses, IRS Form 5500 filings, actuarial studies and PBGC premiums.
PBGC premiums will be substantially lower than you would pay per participant for a single-employer pension plan, so more of your pension dollar will go toward employee benefits, where it belongs. Premium rates for the National Pension Plan are $27.00 per participant per year. Compare that to $64.00 per participant per year, which is the minimum PBGC premium rate for a single-employer plan in 2016. The PBGC single-employer plan variable rate cap for 2016 is $500 per participant.
In addition, your contributions cover the cost of obtaining ongoing IRS tax qualification, which assures tax deductibility of your contributions.
