401(k) Third-Party Administrators: Compare Testing, Filing and Recordkeeper Handoffs

Map the recurring work before comparing providers

TPAs commonly handle plan documents, testing and Form 5500 preparation; recordkeepers maintain participant accounts; and employers supply data, approvals and notices—but contracts determine many handoffs.[1][3]

• TPA: Common services include plan design and document maintenance, annual nondiscrimination testing, Form 5500 preparation or coordination, amendments, and some loan or distribution processing.[1][2][3]
• Recordkeeper: Common responsibilities include maintaining account data, processing investment transactions, tracking contributions by source, handling enrollment, providing participant account access and delivering most fee disclosures.[1][3]
• Employer: Definiti assigns the sponsor duties such as uploading payroll contributions, supplying accurate year-end census data, executing documents, distributions and Form 5500s, and delivering required notices.[3]

Preparation and execution should be listed separately. A TPA may prepare or coordinate Form 5500 work, while the sponsor executes the filing.[1][3] A distribution may likewise require separate review, approval and payment steps.

Some duties have no universal allocation. Human Interest lists quarterly statements among common administration services, while Definiti assigns participant statements to the recordkeeper.[1][3] Allocate statement delivery, vesting and participant support in the actual service schedule rather than infer them from a provider label.

For each recurring duty, the contract schedule should identify the primary owner, required inputs, approver, deadline and escalation contact. For multistep work, define statuses such as data supplied, testing completed, sponsor approved and filing or transaction completed.

Separate delegated services from sponsor responsibilities

DOL identifies selecting and monitoring a provider as a fiduciary responsibility. Use a documented selection process, identical plan information, assessment of qualifications and fees, and periodic review of performance and actual charges.[4] Outsourcing daily work does not establish that every sponsor duty has transferred; define delegated discretion precisely.[3]

The Retirement Advantage says fiduciary status depends on functions—particularly discretion or control—rather than title. It describes establishing, amending, selecting plan features or terminating a plan as employer business decisions, while implementing those decisions may involve fiduciary conduct.[2]

The responsibility schedule should identify the primary owner, approver and handoff for:

• participant statements and vesting calculations;
• loan and distribution review, approval and processing;
• participant notices and plan amendments;
• Form 5500 preparation, review and execution; and
• error identification, correction decisions and implementation.

Obtain legal review before relying on a provider’s description of assumed fiduciary functions.

Normalize bids to one scope and fee worksheet

Give every bidder the same plan profile, census assumptions, requested services, transaction scenarios and response format. The Retirement Advantage recommends surveying multiple providers using the same requirements so the selection process produces a meaningful, documented comparison.[2]

• Separate the roles. List administration and recordkeeping independently, even when one company provides both. Human Interest notes that some recordkeepers include TPA services, while others work with independent administrators.[1]
• Normalize fees. Require each charge to be classified as bundled annually, per participant or per service, then request a total-cost calculation using common assumptions.[1]
• Use consistent evidence. Human Interest recommends examining experience with comparable plans, relevant credentials such as QPA, QKA or ASPPA designations, accuracy, timeliness, responsiveness and technology.[1]

Ask for client references, sample service reports and documentation supporting performance claims. Record unanswered questions as proposal exceptions rather than assumptions.

Compare integrated and separately appointed administration

Human Interest

Human Interest describes integrated administration and recordkeeping, compliance tools and payroll syncing for small and midsized employers.[1] Confirm which testing, document and filing tasks are contractual, which are optional, and who approves corrections or distributions.

Definiti

Definiti describes administration, recordkeeping and ERISA 3(16) fiduciary services.[3] Identify the contracted package and named provider; availability of a fiduciary service does not mean every engagement transfers the same discretion or sponsor duties.

A separately appointed TPA

Name both administrator and recordkeeper, then allocate payroll data, testing, amendments, participant communications, approvals and filing completion. Compare the combined cost and one reconciled schedule. An old demo-site description is not proof of a current employer-facing offer.

What to confirm with each provider

The cited Human Interest, Empower and Definiti pages do not state exact administration prices, plan-size limits, complete contract and cancellation terms, service levels or detailed exit deliverables.

• Pricing: Request minimum fees, setup or conversion charges, per-participant rates, distribution and loan charges, amendment and testing fees, asset-based charges, escalation terms and termination charges.
• Eligibility and scope: Confirm participant-count limits, supported plan designs, excluded transactions and whether administration and recordkeeping are bundled or separate.
• Contract and cancellation: Confirm the contract term, renewal process, notice requirements, cancellation charges and post-termination support.
• Performance: Request service levels for testing, filings, corrections, transaction processing and support responses, along with evidence of accuracy and timeliness.
• Exit records: Specify data formats; participant account and loan histories; payroll and contribution files; testing workpapers; signed plan documents and amendments; and Form 5500 records.
• Transition support: Assign responsibility and deadlines for blackout support, asset-transfer reconciliation, rejected-file correction and final contribution reconciliation.

For each exit deliverable, identify owner, deadline, format and acceptance criteria. Address archive access, corrections, conversion assistance, cybersecurity and file charges. Keep the monitoring record through transition, including reports, actual fees, performance and participant complaints.[4]

Decision rule: Compare the documented scope and total cost of entering, operating and leaving each arrangement.
