What it means
A defined benefit plan promises a set pension, and somebody has to calculate how much money must go in each year to deliver it. In a fully insured plan the employer sidesteps investment uncertainty by buying level premium insurance contracts whose guarantees are sized to pay the promised benefit at retirement.
Because the funding rests on the insurer's conservative guaranteed rates rather than hopeful market returns, the required annual premium is high, and that premium is generally deductible for the employer. For an older business owner with a short runway to retirement and strong profits, the deduction can be several times what any defined contribution arrangement would allow.
The trade-off is rigidity and cost. Premiums must be paid on schedule, the contracts carry charges and commission, and the plan is expensive to unwind, so a dip in profits can turn a tax advantage into a cash flow problem.
These plans attracted abuse through contracts engineered with artificially high early premiums and suppressed early cash values, designed to inflate the deduction and later move value to the owner cheaply. Tax authorities challenged such designs, published guidance against them and treated the worst as reportable arrangements, which is why the structure needs careful and conservative advice.
Used properly, a fully insured plan is a legitimate way for a small professional firm to fund a real pension with certainty about the outcome. The modern reference is 412(e)(3), and the hallmarks of a sound plan are a genuine benefit promise, standard contracts and proper benefits for every participant rather than the owner alone.
In practice
Real-world examples.
Example
A 58-year-old architect running a two-person firm with $400,000 of profit sets up a fully insured plan and funds $150,000 a year, cutting taxable profit sharply while building a guaranteed pension. Her adviser models the next seven years of premiums against forecast profit before she signs anything.
Example
A medical practice is sold insurance contracts with unusually high first-year premiums and very low early cash values. Its new accountant flags the design as the type tax authorities have challenged, and recommends replacing the contracts with standard ones and correcting the filings.
Example
A manufacturer with 30 staff rejects a fully insured plan because a fixed premium obligation does not suit a cyclical order book. It chooses a 401(k) with a discretionary employer match instead, accepting a smaller deduction for far more flexibility.
Formula
Calculation
Annual premium = the level amount the insurer requires so that the guaranteed value of the contracts at retirement funds the promised benefit.
A practice owner aged 55 wants a pension of $60,000 a year from age 65. The insurer prices that promise at $750,000 of guaranteed value needed at age 65, and quotes a level annual premium of $75,000 payable for ten years, so the employer pays 10 x $75,000 = $750,000 of premium in total and the contracts mature in time to provide the benefit. The business funds $75,000 a year as a deductible pension cost, against the far smaller amount a profit sharing arrangement would allow on the same salary, and the cost is fixed rather than dependent on how markets perform.Case study
Seen in the real world.
Calder Vale Dentistry is a fictional practice used purely as an illustrative example. Its sole owner was 57, drew $280,000 a year, employed two hygienists and wanted to catch up on retirement saving in under a decade.
In the illustrative story the practice funded a fully insured plan at $120,000 a year, with proportionate benefits for the two employees, and the deduction cut its taxable profit to a level the owner was comfortable with. Two years in, a long refurbishment and a staff absence halved profits, and the fixed premium had to be paid regardless.
The fictional owner covered the shortfall from a business loan and later reduced the benefit promise, which required actuarial work and legal fees. The illustrative lesson is that the size of the deduction is only attractive if the business can meet the premium in a bad year as well as a good one.
Watch out
Common mistakes.
- Believing 412(i) is still a live code section, when the rules moved to 412(e)(3) and only the nickname survived in everyday use.
- Treating the large deduction as the purpose of the plan rather than a consequence of funding a real pension promise on conservative assumptions.
- Assuming premiums can be skipped in a bad year the way a discretionary profit sharing contribution can be.
Questions
People also ask.
Why are these plans associated with tax abuse?
Promoters once used contracts with inflated early premiums and suppressed cash values to manufacture deductions, and the authorities responded with guidance, penalties and disclosure requirements.
Who is a fully insured plan actually suitable for?
Typically an older owner of a small, consistently profitable professional firm who wants certainty and a large deductible contribution, with few other employees to fund alongside.
Can the plan be terminated early?
Yes, but surrender charges, the loss of guarantees and the rules on distributing plan assets make early termination costly, so the exit should be modelled before the plan is set up.
