Administer 401(k), 403(b), 457(b), Defined Benefit, and Pooled Employer Plans from a single, audit-ready system built for TPAs, sponsors, and recordkeepers. The current state: retirement administration lives in too many places If you administer employer-sponsored retirement plans for a living, you already know the shape of the work. A single plan touches recordkeeping , contribution processing , compliance testing , participant management , government filings, and year-end reconciliation. Multiply that by dozens or hundreds of plans, each with its own document, eligibility rules, vesting schedule, and payroll feed, and the operational surface area becomes enormous. Today, most third-party administrators (TPAs), plan sponsors, and recordkeepers stitch this together from a patchwork of tools. A recordkeeping ledger sits in one system. Compliance tests run in spreadsheets or a separate testing engine. Contribution files arrive by email, SFTP, or a payroll portal and a...

The current state: defined benefit administration is stitched together across spreadsheets and valuation systems
Of every plan type in the retirement industry, the traditional Defined Benefit (DB) pension plan — and its increasingly popular cousin, the cash-balance plan — carries the heaviest administrative burden. A DB plan does not simply track an account balance the way a 401(k) does. It makes a promise: a specific benefit, calculated by formula, payable at retirement. Keeping that promise properly administered means tracking accrued benefits over a career, running annual actuarial valuations, monitoring plan funding, calculating lump-sum conversions and optional forms of payment, coordinating with the PBGC, and running pension payroll for retirees — often for decades after an employee's active service ends.
Today, this work is still done largely across a patchwork of spreadsheets, standalone actuarial valuation software, and payroll tools that were never designed to talk to each other. An actuarial firm or DB third-party administrator typically maintains a census of participant service and compensation history in one place, runs the funding valuation in a separate actuarial system, calculates individual benefit estimates and lump sums in yet another tool, and hands pension payroll off to a system that has no direct connection to any of it. Each handoff is a place where a number can be transcribed incorrectly, a mortality basis can drift out of date, or a segment rate can be applied from the wrong year.
Cash-balance plans, which express the promised benefit as a hypothetical account that grows with pay credits and interest credits rather than a traditional accrual formula, are the fastest-growing design in the DB space — increasingly adopted by professional firms, medical groups, and closely-held businesses that want to stack large, tax-deductible contributions on top of a 401(k). But a cash-balance plan is still, legally, a defined benefit plan, and it still requires the same actuarial valuation, funding, and benefit-security machinery underneath the more approachable "account balance" presentation participants see.
The specialist capacity to administer either design correctly — actuarial firms and DB-focused TPAs — is genuinely scarce relative to the demand, which means the manual, spreadsheet-driven approach is not just inconvenient. It is a real constraint on how many plans a qualified firm can responsibly take on.
The pain point: where DB administration is exacting, technical, and genuinely dangerous to get wrong
A defined benefit plan carries a different category of risk than a defined contribution plan. In a 401(k), an administrative error usually affects one participant's account. In a DB plan, an error in the actuarial assumptions, the funding calculation, or the benefit formula can misstate the plan's obligations across the entire participant population, with consequences for funding, for PBGC premiums, and for the sponsor's balance sheet. Here is where the friction and the risk concentrate:
Accrued benefit tracking. Every participant's benefit has to be calculated and updated based on their service and compensation history, using the plan's specific accrual formula — unit credit, flat-benefit, career-average, flat-dollar, or a cash-balance pay-and-interest-credit design. Reconstructing that history accurately, year over year, across a career, is exacting work, and an error early in a career compounds for decades.
Actuarial coordination and the annual funding valuation. The §430 funding valuation determines the plan's Funding Target and Target Normal Cost, drives any shortfall amortization, and sets the §404(o) maximum deductible contribution. This depends on current mortality tables, segment interest rates, and plan-specific assumptions, and it has to be handed to an enrolled actuary for review and certification on Schedule SB — a step no system should try to skip or automate away.
§417(e) lump-sum conversions and optional forms. Converting an accrued benefit into a lump sum, or into an optional form of payment such as a joint-and-survivor annuity, uses specific segment interest rates and mortality assumptions under §417(e), along with relative-value comparisons across the available optional forms and the QJSA/QPSA requirements under §417(c). A stale rate or the wrong mortality basis produces an incorrect payout.
AFTAP restrictions. A plan's Adjusted Funding Target Attainment Percentage under §436 determines whether certain benefit restrictions — on lump-sum payments, on plan amendments that increase benefits — are actually in effect. Missing an AFTAP-driven restriction and paying a lump sum that should have been restricted is a real compliance failure, not a paperwork oversight.
PBGC premiums and the maximum guarantee. Most single-employer DB plans owe annual PBGC premiums under ERISA §4006, calculated from participant counts and funding data, and the §4022 maximum guarantee caps what the PBGC would pay if the plan terminated underfunded. Both depend on the same underlying census and funding data used elsewhere in administration, and any disconnect between systems creates a reconciliation problem.
Testing that a DB plan still has to pass. §401(a)(26) minimum participation, §410(b) coverage, top-heavy status under §416, and nondiscrimination in the amount of benefits under §401(a)(4) — including permitted-disparity calculations — all still apply to DB and cash-balance plans, on top of the funding and benefit-calculation work.
Pension payroll for decades. Once a participant retires, the plan may be paying them a monthly benefit for the rest of their life, with cost-of-living adjustments where applicable, survivor-benefit transitions at death, required minimum distribution timing, and correct 1099-R coding — a payroll obligation that can run far longer than the participant's working career.
Underneath all of it is the same scaling problem that constrains every fragmented administrative model, but sharper: DB and cash-balance work requires genuine actuarial specialization, and that specialist capacity does not scale by simply hiring more junior staff. A firm's growth is capped by how much of this technical, high-stakes calculation its actuaries and senior administrators can personally verify.
RetireCore-DB: the actuarial spine, coordinated with your actuary — not replacing them
RetireCore-DB from HolyByte Innovations is an enterprise administration system for traditional defined benefit and cash-balance plans, built around three principles. Straight-through processing: every plan event — an accrual update, a valuation run, a retirement election, a distribution, pension payroll — flows through one auditable pipeline instead of being rebuilt by hand at each handoff. Honest AI: where the platform uses AI to read or judge a document, it says so honestly when it cannot be confident, routes the item to a human, and no live rate or figure feeds a filing-grade calculation until an enrolled actuary has accepted it. Compliance as code: the cited IRC, ERISA, and PBGC checks that apply to a DB plan run against live census data, with plan rules, assumptions, and IRS figures configured as data rather than hardcoded into the software.
RetireCore-DB is explicit about where it stands relative to the professionals who sign off on this work: it is built to be the shared, reliable foundation that actuarial firms, DB third-party administrators, and enrolled actuaries work from — not a replacement for actuarial judgment or signature. Every actuarial output is treated as unsigned until a qualified enrolled actuary reviews and accepts it, and a live IRS rate feed stays in review-only status until that acceptance happens.
Key features for defined benefit administration
The features below reflect the real actuarial and compliance mechanics of a DB or cash-balance plan, kept organized and reconciled rather than rebuilt at every handoff.
Real actuarial accrual, across every common design
RetireCore-DB supports unit-credit, flat-benefit, career-average, and flat-dollar accrual formulas for traditional designs, along with pay-and-interest-credit cash-balance calculations. Each participant's accrued benefit is derived from their tracked service and compensation history, using the plan's own configured formula rather than a generic approximation.
§430 funding valuation, built on current primary-source data
The platform runs the §430 Funding Target and Target Normal Cost calculation, shortfall amortization, and the §404(o) maximum deductible contribution, built on real, current IRS data — including current IRS static mortality tables and published segment and §417(e) rates, along with the applicable §415(b) maximum benefit and §401(a)(17) compensation cap figures. Every year-dependent figure lives in a year-keyed table an administrator updates when new IRS guidance is released, with no code change required.
§417(e) lump sums and optional forms, done correctly
Lump-sum conversions apply the correct §417(e) segment rates and mortality basis, and optional forms of payment — straight-life annuity, joint-and-survivor at 50%, 75%, or 100%, and life-certain forms — are compared on a relative-value basis consistent with the QJSA and QPSA requirements under §417(c). Late-retirement actuarial increases under §411(a)(9) are calculated for participants who continue working past normal retirement age.
AFTAP and PBGC obligations tracked alongside the valuation
AFTAP determinations under §436 are tracked so that lump-sum and amendment restrictions apply automatically when the plan's funded status requires them, rather than depending on a separate manual check. PBGC premium calculations under ERISA §4006, and the §4022 maximum guarantee that bounds what the PBGC would pay on an underfunded termination, run from the same census and funding data used everywhere else in the platform, eliminating the reconciliation gap between funding, premiums, and benefit calculations.
The compliance testing a DB plan still has to pass
§401(a)(26) minimum participation, §410(b) coverage, top-heavy status under §416, and §401(a)(4) nondiscrimination in the amount of benefits — including permitted-disparity calculations — run against live census data with cited results, alongside the funding and benefit work, rather than as a separate exercise assembled from a different data set.
Pension payroll built for the long run
Once a participant retires, RetireCore-DB handles ongoing pension payroll, including cost-of-living adjustments where the plan provides them, survivor-benefit transitions at a retiree's death, required minimum distribution timing, and the correct Form 1099-R references — a payroll obligation the platform is built to sustain for as long as the plan continues to pay that participant.
Four reconciliation invariants, proven on real census data
RetireCore-DB is built and verified against four reconciliation invariants, tested on real census data for both traditional and cash-balance designs: every participant's benefit is fully determined; the sum of each participant's present value of accrued benefit ties to the funding target at $0 variance; every vested accrued benefit stays within the bounds of the full accrued benefit; and the trust identity — beginning assets plus contributions plus investment return, minus benefits and expenses, equals ending assets — holds to $0. These checks are encoded as automated regression tests, so they cannot silently break as the plan's data changes.
Honest about the enrolled actuary's role
The platform is deliberately built to keep the enrolled actuary in the loop rather than route around them. Actuarial output is treated as unsigned until a qualified actuary reviews it, Schedule SB requires that actuary's signature before it is filed, and a live IRS rate feed remains review-only until the actuary accepts it into a calculation. RetireCore-DB is also honest about its current scope: the loaded static mortality tables cover plans at or under 500 participants, multiemployer and CSEC plans, and the §417(e) unisex basis, with generational tables for plans over 500 participants on the roadmap.
Privacy-first, and part of a broader family
RetireCore-DB runs entirely on the administrator's or actuarial firm's own machine — participant and census data never leaves it. It shares its architecture and license structure with RetireCore's standalone 401(k), 403(b), and 457(b) products, so a firm that administers both DB and DC business, as most do, can extend the same platform across its full plan lineup.

Who it is for, and how it changes the day-to-day
Consider an actuarial firm or DB TPA running annual valuations for a book of traditional pension and cash-balance clients. In the fragmented model, the census lives in one spreadsheet, the valuation runs in a separate actuarial system, individual benefit estimates and lump sums are calculated in yet another tool, and pension payroll runs disconnected from all of it. Every handoff between those systems is a place a number can drift — a compensation update that never made it into the valuation, a mortality table that is one year stale, a lump-sum quote calculated against last year's segment rates.
With RetireCore-DB, the census, the funding valuation, benefit calculations, and pension payroll read from the same underlying data and the same year-keyed assumption tables. When a valuation runs, it is built on the same service and compensation history that drives every individual benefit calculation. When a participant retires and elects a lump sum, the conversion uses the same current segment rates the valuation used. The enrolled actuary still reviews and signs the work — that professional judgment is not automated away — but the data reaching them is reconciled and current rather than reassembled by hand from disconnected sources.
Frequently asked questions
Does RetireCore-DB replace the need for an enrolled actuary?
No. RetireCore-DB is built to keep the enrolled actuary in the loop, not to route around them. All actuarial output is treated as unsigned until a qualified enrolled actuary reviews and accepts it, and Schedule SB still requires that actuary's signature before filing. The platform's job is to keep the underlying data, calculations, and assumptions organized and reconciled so the actuary's review is working from a reliable foundation.
Does RetireCore-DB support cash-balance plans as well as traditional pensions?
Yes. It supports unit-credit, flat-benefit, career-average, and flat-dollar accrual for traditional DB designs, and pay-and-interest-credit calculations for cash-balance plans, with reconciliation invariants proven on real census data for both plan designs.
How does RetireCore-DB handle lump-sum payouts and optional forms of payment?
Lump-sum conversions apply the applicable §417(e) segment interest rates and mortality basis, and optional payment forms — including joint-and-survivor and life-certain options — are compared on a relative-value basis consistent with the QJSA and QPSA requirements under §417(c), with late-retirement actuarial increases calculated under §411(a)(9) where applicable.
What compliance testing does RetireCore-DB run for defined benefit plans?
It runs §401(a)(26) minimum participation, §410(b) coverage, top-heavy status under §416, and §401(a)(4) nondiscrimination in the amount of benefits, including permitted-disparity calculations, alongside the AFTAP §436 determination and PBGC premium calculation under ERISA §4006.
Are the mortality tables and IRS figures current?
RetireCore-DB is built on current primary-source IRS data, including current static mortality tables and published segment and §417(e) rates, §415(b) maximum benefit, and §401(a)(17) compensation cap figures. All year-dependent figures live in a year-keyed table an administrator updates as new IRS guidance is released, without requiring a software upgrade.
