Yes. A cash balance plan is a defined benefit plan under IRC §401(a), which means it operates under the same incidental benefit framework that governs all qualified pension plans. Life insurance is allowed inside the plan trust, but it can never become the primary purpose of the plan. The plan itself becomes the owner of the policy, the participant is the insured, and the participant names a beneficiary — typically a spouse or children.

Traditional defined benefit and cash balance plans do not restrict the type of insurance policy used, so whole life, universal life, or variable life policies can all be utilized alongside the plan’s other investments. The key requirement is that the policy be a cash-value product and that the arrangement satisfy the IRS incidental benefit limits.

The core appeal is funding permanent life insurance with pre-tax dollars. The strategy combines maximum retirement deductions with permanent life insurance funded on a pre-tax basis, which can be especially valuable for high-earning owners who would otherwise pay premiums out of after-tax income.

There are two main structural benefits. First, the policy acts as an asset of the plan, so the cash value is part of the participant’s hypothetical account and helps deliver the promised retirement benefit. Second, the death benefit ensures that the plan can be completed if the participant dies prematurely, providing financial protection for the participant’s family. Beyond that, the strategy opens up estate planning opportunities and can be coordinated with buy-sell agreements between business partners.

This is not a mass-market planning tool. Successful business owners and professionals over age 45 with stable, high earnings — physicians, attorneys, consultants, and small-business owners with few employees — benefit most. The economic case generally requires strong, predictable cash flow and a genuine need for permanent death benefit protection.

Other good fits include entrepreneurs who want both life insurance and a tax deduction, individuals trying to maximize plan contributions, people with health ratings that make after-tax premiums expensive, and business owners who want to fund a buy-sell agreement on a deductible basis — where the surviving owner is named as beneficiary and receives the proceeds needed to buy out the deceased owner’s interest.

For life insurance to be effective within a cash balance plan, it should be a cash value insurance product. Typically, cash balance plans utilize either a whole life policy or a universal life policy with a guaranteed interest rate. Term insurance is generally not used because it builds no cash value to contribute to the participant’s account balance.

The policy type also affects how much premium you can run through the plan. Under the incidental benefit limits, aggregate whole life premiums must stay below 50% of the theoretical contribution, while term or universal life premiums must stay below 25%. Combination policies that include a whole life base with a term rider apply both tests, with the combined cost not exceeding the limit. The reason whole life gets the higher threshold is mechanical — roughly half of a whole life premium builds cash value rather than pure insurance protection.

The 50% rule from Rev. Rul. 74-307 is one of the ways the IRS measures whether insurance inside a qualified plan is truly “incidental” — a side dish rather than the main course. In a regular defined contribution plan, the rule is simple: less than 50% of the employer money going into a participant’s account can pay whole life premiums, and less than 25% if the policy is term or universal life.

Cash balance plans don’t work the same way because participants don’t receive a real dollar contribution — they receive a hypothetical pay credit. To solve this, the IRS uses the individual level premium funding method to calculate a “theoretical contribution” for the participant, and the 50%/25% test is applied to that figure.

For example, if the theoretical contribution comes out to $80,000, the whole life premium must be less than $40,000 per year, or less than $20,000 for term or universal coverage. Cross that line and the plan has a qualification problem.

The 100-to-1 rule is the second test that runs in parallel with the percentage test. A cash balance plan must satisfy both the percentage test (the 50% rule for whole life and 25% rule for term or universal life) and the 100-to-1 rule, which limits the death benefit to no more than 100 times the projected monthly retirement benefit. Both tests must be passed independently, and failing either one puts the plan’s qualified status at risk.

Practically, this caps how much coverage you can carry inside the plan based on the size of the retirement benefit being promised. In a fully insured 412(e)(3) plan, the same 100-to-1 limit applies — the death benefit cannot exceed 100 times the participant’s monthly retirement benefit.

PS 58 refers to IRS Revenue Ruling 74-307 and its predecessor, Revenue Ruling 55-747, and it represents the cost of pure life insurance protection provided to a participant when a policy is held inside a qualified retirement plan. When the plan owns a policy, part of the annual premium goes toward cash value and part covers pure death benefit protection. The IRS treats the death benefit portion as an economic benefit to the participant, which must be reported as taxable income each year.

This is essentially phantom income — the participant pays tax on a benefit they don’t actually receive in cash. The amount is reported annually on Form W-2 (for employees) or Form 1099-R (for plan distributions), even though the participant may not receive any plan distributions for many years. Importantly, the PS 58 cost is usually small relative to the plan’s overall tax deduction, so the net economics still favor the business owner in most cases.

The math involves three pieces: the net amount at risk, an IRS rate table, and the participant’s age. Each policy anniversary, the administrator pulls the death benefit and cash surrender value, subtracts the cash value from the death benefit to determine the net amount at risk, applies the appropriate Table 2001 rate based on the participant’s age (or the insurer’s published one-year term rate if it is lower and qualifying), and reports the imputed income to the participant — typically on a 1099-R from the plan trust.

Table 2001 provides an annual cost per $1,000 of coverage based on the insured’s age. For example, a 55-year-old has a rate of $4.15 per $1,000, so a participant with a $1 million net amount at risk would report roughly $4,150 of imputed income that year. The reported amount also becomes basis the participant can later use to offset taxation when the policy is eventually distributed or sold out of the plan.

Life insurance cannot live inside a qualified plan indefinitely. The IRS does not permit a participant to retire or take a distribution while still holding a policy inside the plan, so the insurance must be dealt with in one of several IRS-approved ways before any retirement distribution can occur. There are four primary options, and the right choice depends on the participant’s age, health, tax situation, and whether they want to keep the coverage outside the plan.

The four main routes are surrendering the policy for its cash surrender value, distributing the policy in kind to the participant (who is then taxed on the fair market value under IRC §402(a)), having the participant purchase the policy from the plan at fair market value, or selling it to a third party such as an Irrevocable Life Insurance Trust. A common technique is to sell the policy to an ILIT for fair market value, which removes the death benefit from both the plan and the participant’s taxable estate. Planning the exit well in advance is essential — waiting too long meaningfully narrows the available options.

The biggest one is administrative complexity. A defined benefit plan is funded based on an actuarial valuation that depends on the fair market value of plan assets at the valuation date. Permanent life insurance, particularly whole life, is notorious for poor early-year cash value performance — surrender charges, front-loaded commissions, and acquisition costs mean that in years one and two the cash surrender value can be a small fraction of the premiums paid. From the actuary’s perspective, that looks like a significant investment loss, which can flow through and increase the minimum required contribution beyond what the owner anticipated.

There are also compliance trip-wires. Cash balance plans are subject to strict nondiscrimination and coverage testing, and if life insurance is offered to owners, comparable coverage may need to be offered to non-highly-compensated employees, which can erode the economics. Required minimum distribution rules at age 73 are harder to satisfy when a meaningful share of the participant’s balance is illiquid policy value, and plan termination with a policy still in force is significantly more complex than terminating a fully liquid plan.

Life insurance inside a cash balance plan can be a strong strategy for the right candidate, but the economic case has to be strong enough to justify the additional actuarial work, annual PS 58 reporting, and exit planning that come with it.
