Section 412(e)(3) Plans
412(e)(3) vs a Traditional Defined Benefit Plan: How They Differ
Published October 9, 2026 · Updated October 9, 2026
Short Answer: One Plan Type, Two Funding Paths
A 412(e)(3) plan is not a different kind of plan: it is a defined benefit plan funded only by insurance or annuity contracts that meet six statutory conditions, which exempts it from the minimum funding standard. A traditional defined benefit plan is usually funded through a trust, remains subject to that standard and files Schedule SB.
Both promise what the IRS describes as "a benefit based on a fixed formula." The 412(e)(3) label replaced the older "412(i)" name after the Pension Protection Act of 2006, so a "412i vs defined benefit plan" search asks the same question.
Business owners, partners and owner-employees of closely held companies usually weigh this choice when designing an owner-heavy retirement benefit. Business Life Insurance treats the insurance contract here as the funding mechanism inside a business benefit plan, not as the plan itself. This comparison covers funding mechanics, tax treatment, Form 5500 filing and the section 415(b) benefit limit.
At-a-Glance Comparison
| Criterion | 412(e)(3) fully insured plan | Traditional defined benefit plan |
|---|---|---|
| Funding mechanism | "Funded exclusively by the purchase of individual insurance contracts" (26 U.S.C. § 412(e)(3)(A)), or qualifying group contracts | Assets held for the plan. The investment mix varies by plan |
| Minimum funding standard | Does not apply (26 U.S.C. § 412(e)(2)(B)) | Applies under 26 U.S.C. § 412 |
| Schedule MB/SB with Form 5500 | Neither is required (2025 Form 5500 Instructions) | Form 5500 with Schedule SB filed annually (IRS) |
| Enrolled actuary | No Schedule SB to sign | An enrolled actuary determines funding levels and signs Schedule SB (IRS) |
| Benefit limit | 26 U.S.C. § 415(b) | 26 U.S.C. § 415(b) |
| Contribution predictability | Each contract must provide for level annual premium payments, with payments for a benefit increase starting when it takes effect (26 U.S.C. § 412(e)(3)(B)) | Required contributions follow the funding rules each year |
| IRS compliance history | IRS guidance issued in 2004 and 2005 targets abusive insurance designs. Some arrangements are listed transactions | Minimum funding rules under 26 U.S.C. § 412 apply |
Option A: The 412(e)(3) Fully Insured Defined Benefit Plan
Under 26 U.S.C. § 412(e)(3), a plan qualifies as a fully insured plan only when all six of the following conditions are met:
- (A) Exclusive funding. It "is funded exclusively by the purchase of individual insurance contracts."
- (B) Level premiums. The contracts provide for level annual premiums. The premiums run from the date the person became a participant (or from the date of a benefit increase) and end no later than the participant's retirement age.
- (C) Benefits match the contracts. Plan benefits equal the benefits provided under each contract at normal retirement age. The statute requires that a state-licensed insurance carrier back those benefits "to the extent premiums have been paid."
- (D) Premiums paid. Premiums for the plan year and all prior plan years have been paid before lapse, or the policy has been reinstated.
- (E) No security interest. No rights under the contracts have been subject to a security interest during the plan year.
- (F) No policy loans. No policy loans are outstanding during the plan year.
A plan funded exclusively by group insurance contracts that Treasury regulations determine to have the same characteristics is also treated as a fully insured plan. The six statutory conditions carry their own detailed treatment.
Mechanics. Under 26 C.F.R. § 1.412(i)-1, the contracts are bought from licensed insurers "either directly by the employer or through the use of a custodial account or trust." The contracts, bought either way, fund the promised benefit. Cash value is a feature of the contract, not an investment account.
Exemption and filing. Section 412(e)(2)(B) excludes these plans from the minimum funding rules. The 2025 Form 5500 Instructions state that "neither the Schedule MB nor the Schedule SB is required."
Costs and risks. Premiums must be paid before lapse, and a missed payment, an outstanding policy loan or a security interest can take the plan outside the exemption. The IRS has also issued guidance aimed at abusive designs.
Option B: The Traditional Defined Benefit Plan
The IRS describes this plan type this way: "A defined benefit retirement plan provides a benefit based on a fixed formula." The IRS Retirement Plans Definitions page adds that such a plan, "also known as a traditional pension plan," promises a specified monthly benefit. That benefit is often based on salary, age and years of service.
Funding. The plan holds assets that pay benefits. Because 26 U.S.C. § 412 applies, the plan must satisfy the minimum funding standard for each plan year (§ 412(a)(1)); for a defined benefit plan that is not a multiemployer plan, that means employer contributions of at least the minimum required contribution determined under § 430 for the plan year (§ 412(a)(2)(A)).
Filing. The IRS states that a sponsor needs to "annually file a Form 5500 with a Schedule SB" and to "have an enrolled actuary determine the funding levels and sign the Schedule SB."
Advantages the IRS names. Employers "can contribute (and deduct) more than under other retirement plans," in the IRS's words, with deductions subject to the limits in 26 U.S.C. § 404(a). The benefit is predictable and "not dependent on asset returns." Vesting can follow a variety of schedules.
Costs and constraints. The IRS notes that these plans "are often more complex and, thus, more costly to establish and maintain." A sponsor "can't retroactively decrease benefits." The IRS definitions page also explains that, under ERISA, payment of certain benefits of a terminated defined benefit plan is covered through the Pension Benefit Guaranty Corporation.
Key Differences Between the Two Structures
The central difference is what funds the promise.
| Point of difference | 412(e)(3) plan | Traditional plan |
|---|---|---|
| What funds the benefit | Insurance contracts, which define the funding | Plan assets, measured against the minimum funding standard |
| Annual contribution | The level premium the contract sets | Can change as the funding calculations are updated |
| Actuarial filing | No Schedule MB or SB (2025 Form 5500 Instructions) | Actuarial certification on Schedule SB (IRS) |
Where the exemption comes from. The 412(e)(3) plan's lighter actuarial filing follows from the 26 U.S.C. § 412(e)(2)(B) exemption. That exemption holds only while every condition in section 412(e)(3)(A)-(F) is met.
IRS scrutiny. The IRS issued guidance in 2004 and 2005 "to stop abuses involving the use of certain specially designed life insurance policies in retirement plans."
Shared limits. Both plans fall under the section 415(b) benefit limit and the section 404 deduction rules.
Tax Treatment Compared
The section 264(a)(1) rule comes first: "No deduction shall be allowed for— (1) Premiums on any life insurance policy, or endowment or annuity contract, if the taxpayer is directly or indirectly a beneficiary under the policy or contract."
Contributions. Under 26 U.S.C. § 404(a), employer contributions to a pension plan "shall not be deductible under this chapter; but, if they would otherwise be deductible, they shall be deductible under this section," subject to its limits. That framework applies to both plan types. Section 412(e)(3) plan design, contributions, deductions and premium deductibility under section 264(a)(1) need individual review of the contracts involved by the insurers and a qualified tax professional. The rules on 412(e)(3) tax deductions have their own detailed treatment.
Listed transactions. The IRS states that when "the employer deducts amounts used to pay premiums on a life insurance contract with a death benefit that exceeds the participant's death benefit under the plan by more than $100,000, the arrangement is a 'listed transaction'."
Benefits. Under 26 U.S.C. § 415(b), the annual benefit cannot exceed the lesser of a statutory dollar amount and "100 percent of the participant's average compensation for his high 3 years." The annual benefit is measured as a straight life annuity (§ 415(b)(2)(A)), and the dollar limit is reduced if benefits begin before age 62 and increased if they begin after age 65 (§ 415(b)(2)(C)-(D)). The dollar amount is also adjusted over time, so its figure is confirmed for the plan year. How distributions are taxed depends on the plan and the payment form.
Death benefit. Section 101(a)(1) generally excludes life insurance death proceeds from gross income. Two limits matter in business planning:
- Section 101(a)(2) limits the exclusion after a transfer for value.
- For employer-owned contracts, section 101(j) caps the exclusion at premiums and other amounts paid. The cap lifts only when a section 101(j)(2) exception applies and written notice and consent were given before the contract was issued. Neither one alone lifts the cap.
How these rules reach contracts held in a plan needs that same individual review. Life insurance inside a 412(e)(3) plan is treated in more detail elsewhere.

Who These Plans Are For
This comparison is for owners and finance leads of employer-sponsored businesses who are considering a defined benefit promise. That includes closely held corporations, professional practices, partnerships and sole proprietors. The IRS states that a defined benefit plan sponsor "can be a business of any size" and "can have other retirement plans."
Each structure tends to draw a different kind of employer:
- A fully insured plan is often weighed by smaller and closely held employers. These include owner-only practices and firms with few employees, where level contributions and a lighter actuarial filing carry weight.
- A traditional plan is often weighed by employers that can carry actuarial and administrative work and prefer a plan that holds its own assets.
Both structures commit the employer to funding a promised benefit. Which one fits a given business depends on several facts:
- the workforce and who will participate
- cash flow over many years
- tolerance for administrative complexity
- the terms of the contracts involved
Neither structure suits every business.
When a 412(e)(3) Plan May Fit
A closely held business with steady cash flow, able to carry level premiums for years, typically weighs the fully insured design. The owner-employee in that business often values knowing the annual cost in advance.
Such an employer usually places weight on two features. One is the section 412(e)(2)(B) exemption from minimum funding. The other is the absence of a Schedule MB or SB filing.
The fit also assumes the employer accepts certain constraints:
- The contract terms control the funding.
- Premiums are paid on time.
- No policy loans are taken.
- No security interest is placed on the contracts.
Owners considering this path typically confirm with their advisers that the design meets every requirement in section 412(e)(3)(A)-(F). They also confirm that it does not fall within the IRS listed-transaction description.
When a Traditional Defined Benefit Plan May Fit
An employer with a larger or more stable workforce may weigh a traditional plan. This is especially so when it can absorb the actuarial and administrative costs the IRS describes. Such an employer typically wants the plan to hold its own assets and accepts that required contributions can change from year to year under the funding standard.
It is usually prepared to engage an enrolled actuary and file Schedule SB every year. Some employers find that their benefit formula and workforce make a trust-based structure more workable than buying individual contracts for each participant.
An employer in this position is not seeking the fully insured exemption. It typically understands that, as the IRS describes ERISA, payment of certain benefits of a terminated defined benefit plan is covered through the Pension Benefit Guaranty Corporation.
When Neither May Fit
Some employers cannot commit to funding a promised benefit for many years, and for them neither structure may fit, because both carry that obligation. A business with highly uneven cash flow may also find either form of funding hard to sustain: the fixed premium of a 412(e)(3) plan or the changing required contributions of a traditional plan.
An owner who mainly wants year-to-year flexibility in contributions often looks at defined contribution plans, such as a 401(k) or profit-sharing plan, before either of these. That comparison is covered elsewhere on Business Life Insurance.
A design built mainly to produce deductions beyond what sections 412(e)(3) and 404 allow is a separate case. So is one matching the IRS listed-transaction description. Neither has a place in an ordinary plan comparison, because the IRS has acted against such arrangements.
A Decision Framework: Questions to Ask
These questions frame the decision without answering it:
- Does the business have cash flow steady enough to pay level premiums, or changing required contributions, over many years?
- How many employees will participate, and what would funding their benefits cost under each structure?
- How much weight does the employer place on the funding exemption and the lighter Form 5500 filing? How much on a plan that holds its own assets?
- Do qualified tax, legal and insurance professionals confirm that the design meets section 412(e)(3)(A)-(F) and is not a listed transaction?
- What section 415(b) dollar limit applies for the plan year, and does the intended benefit formula fit within it?
- How do section 264(a)(1) and, for employer-owned contracts, section 101(j) affect how the contracts are owned and who is the beneficiary?
Structure, ownership and tax treatment are confirmed with qualified tax, legal and insurance professionals.
Common Mistakes in Comparing These Plans
A frequent error is treating a 412(e)(3) plan as its own plan type. It is a defined benefit plan that meets an exemption. Several related mistakes follow from the same confusion:
- Reading "412(i)" as a different plan. The IRS explains that the 412(i) provisions "were relocated to IRC Section 412(e)(3)," effective for plan years beginning after December 31, 2007. See the former 412(i) name for the history.
- Assuming insurance funding alone earns the exemption. All six conditions must hold, every plan year.
- Overlooking IRS guidance on abusive designs. That guidance includes the listed-transaction rule.
- Assuming section 264(a)(1) never reaches plan-held contracts. That interaction needs review.
- Assuming section 101(j) does not apply. For an employer-owned contract, notice and consent alone do not lift the cap, and neither does an exception alone.
- Comparing limits from different years. The section 415(b) dollar amount is adjusted, so figures are compared for the same plan year.
Hypothetical Example: Comparing the Two Structures
This example is hypothetical. A professional corporation has one owner-employee, age 50, and no other participants. All figures are round, illustrative only and not drawn from any contract or reader.
Hypothetical 412(e)(3) path
- The plan buys an individual contract with an illustrative level premium of $100,000 a year.
- Five years of premiums total 5 × $100,000 = $500,000. Each year's amount is the same.
- Under the 2025 Form 5500 Instructions, neither Schedule MB nor Schedule SB is required.
Hypothetical traditional path
- The enrolled actuary's illustrative required contributions are $90,000, $110,000, $80,000, $120,000 and $100,000.
- Their total is $90,000 + $110,000 + $80,000 + $120,000 + $100,000 = $500,000.
- Form 5500 is filed with Schedule SB each year.
What the arithmetic shows. Both totals are $500,000, but one path is level and the other varies year to year. Both plans remain subject to section 415(b) and section 404. Actual premiums, contributions and benefit values depend on the contracts involved and are confirmed with the insurers and a qualified tax professional.

Frequently Asked Questions
What are the pros and cons of a 412(e)(3) defined benefit plan?
Its advantages include exemption from minimum funding under section 412(e)(2)(B), no Schedule MB or SB filing, and level premiums. The tradeoffs are that premiums must be paid on time and all six statutory conditions must keep being met. IRS guidance on abusive designs also applies. The basics are covered on the 412(e)(3) plan overview.
What is a disadvantage of a defined benefit plan?
The IRS states that defined benefit plans "are often more complex and, thus, more costly to establish and maintain than other types of plans." A traditional plan adds an annual Schedule SB signed by an enrolled actuary. A 412(e)(3) plan does not file that schedule but must meet the level-premium and other conditions of section 412(e)(3).
Does a 412(e)(3) plan have to file Schedule SB with Form 5500?
No. The 2025 Form 5500 Instructions state that, for a plan funded exclusively by qualifying contracts, "neither the Schedule MB nor the Schedule SB is required to be filed." That statement concerns the two schedules only.
Do both plans have the same benefit limits?
Yes, both are subject to 26 U.S.C. § 415(b). That section caps the annual benefit at the lesser of an adjusted dollar amount and 100 percent of average compensation for the high 3 years. The dollar figure is confirmed for the plan year.
What happened to the 412(i) plan designation?
The Pension Protection Act of 2006 moved the 412(i) provisions to section 412(e)(3), effective for plan years beginning after December 31, 2007. The IRS notes that the regulations still sit in Treas. Reg. § 1.412(i)-1.
Can a 412(e)(3) plan hold investments other than insurance contracts?
No. Section 412(e)(3)(A) requires the plan to be "funded exclusively by the purchase of individual insurance contracts," or qualifying group contracts. Treas. Reg. § 1.412(i)-1 also refers to individual annuity contracts, and it provides that an employer payment needed to comply with section 411(c)(2) (accrued benefit from employee contributions) does not by itself mean the plan is funded otherwise. A plan funded otherwise falls outside the exemption.
Is an enrolled actuary required for a 412(e)(3) plan?
The actuarial signature the IRS describes is on Schedule SB, and a qualifying 412(e)(3) plan does not file Schedule SB. A traditional plan subject to section 412 has an enrolled actuary sign that schedule each year.
