Defined benefit plans under § 414(j) permit annual contributions calculated to fund a target retirement benefit, with the contribution limit set by § 415(b) at the lesser of $280,000 (2025) of annual benefit or 100% of average compensation. Cash balance plans are hybrid DB plans expressing benefits as a hypothetical account balance under § 411(a)(13).
§ 415(b) and the benefit ceiling
2025 maximum annual benefit: $280,000 (indexed). 100%-of-comp limit uses high-three-consecutive-year average comp. Early retirement actuarial reductions apply before age 62; late retirement actuarial increases apply after 65; age 62-65 is the unreduced benefit window.
For a 60-year-old owner with high-three average comp of $300K, the maximum benefit is $280K/year starting at age 65 (5-year horizon). Funding to target this benefit requires substantial annual contributions, computed by the plan actuary using interest and mortality assumptions disclosed in the plan document.
Cash balance plan mechanics
Each participant has a hypothetical account credited with: (i) an annual pay credit (typically defined as a percentage of comp, may differ by class); (ii) an interest credit (a fixed rate, a 30-year Treasury rate, or actual fund performance, subject to § 411(b)(5) market-rate-of-return safe harbor).
The plan is funded actuarially on the same basis as a traditional DB plan but the participant sees the account-balance form. Participant retirement benefit can be taken as a lump sum (the hypothetical balance) or annuitized.
Combined-plan testing — § 1.401(a)(4)-9
A DB/CB plan is typically combined with a DC plan (401(k) + profit sharing) for nondiscrimination testing. The combined plan must satisfy § 401(a)(4) on a benefits basis. The gateway minimum DC contribution for non-HCEs is the lesser of (a) 5% of comp, (b) 1/3 of the highest aggregate normal allocation rate for any HCE, with a hard floor of 7.5% if the combined plan is broadly tested.
Staff cost is the binding economic constraint. For each non-HCE, the employer pays 5-7.5% of comp into the DC plan (plus DB accrual if non-HCEs participate in DB). Modeling annual.
Plan design choices
- Coverage of non-HCEs. Excluding non-HCEs from the DB plan and providing only gateway DC may suffice for coverage if the DC plan covers them.
- Classification. Pay credits may differ by job classification subject to nondiscrimination; common: owner class gets large pay credit, staff class gets minimum credit or DC-only.
- Interest credit. Lower fixed rate (e.g., 4%) reduces participant statements and contribution volatility; market rates introduce variability.
- Funding range. Minimum required contribution under § 430; maximum deductible contribution under § 404(o) (DB cushion amount).
Funding flexibility
Under § 404(o), the deductible limit includes a cushion (up to 50% of unfunded liability for active participants) allowing significant front-loading. Contribution range typically gives 30-50% flex year over year, useful for cash-flow management.
Excise tax under § 4972 on non-deductible contributions to qualified plans. § 4971 excise on missed minimum required contributions. PBGC coverage applies to most ongoing DB plans except plans of professional service employers with < 25 participants under § 4021(b)(13).
Termination/freeze
Plans must be intended to be permanent at adoption but can be terminated with reasonable cause (e.g., business sale, demographic shift). On termination, accrued benefits roll to IRA. Frozen plans continue to age-weight benefits without further accrual.
IRS tends to scrutinize plan terminations within 5 years of adoption; document business rationale.
Integration with 401(k)
The 401(k) profit sharing component handles the employee deferral and the gateway DC minimum. The cash balance overlay carries the owner-favorable contributions. Combined cap per participant: § 415 aggregate limit applies (DB limit + DC limit; not literally additive but practically often near-additive at the owner level).
Client selection criteria
- Net business profit consistently >$300K available for plan funding.
- Owner age 40+ with 5+ years of expected high contribution capacity.
- Low to moderate staff comp ratio relative to owner.
- Tolerance for the annual administrative cost ($5-15K typical, mostly actuarial).
- No imminent business sale (DB plan in place at sale complicates the transaction).
Practitioner posture
- Annual actuarial review. Funding range, demographic shifts, plan design alignment.
- Coordinate with 401(k) TPA. Single TPA handling both plans simplifies combined testing.
- PBGC premium and reporting. If applicable, $111 per participant flat premium plus variable-rate based on unfunded vested benefits.
- Termination planning. Communicate 3+ year horizon to client before termination; sudden terminations invite IRS questions.
