Retirement plan administrators and recordkeepers

Active

Third-party administrators (TPAs) handle plan design, compliance testing, and government filings for 401(k) and other employer retirement plans, mostly for small employers. Recordkeepers keep participant account records, process contributions and trades, and run the participant website, and they are far larger and more concentrated than TPAs.

Workflows to evaluate

Our proposed starting points. Results are not verified.

  • Compliance testing preparation

    Apply plan eligibility rules to payroll census data and draft testing inputs, flagging likely failures early.

    Inputs to confirm
    Plan documents, payroll census files and prior-year test results.
    Human review
    A plan administrator reviews results before they go to the plan sponsor.
    Measure
    Plans that pass review on the first run and late corrective distributions.

    Why: The brief places most TPA labor in census cleanup and rule-based testing. Where AI changes the cost base →

  • Annual filing preparation

    Assemble Form 5500 inputs from reviewed census and recordkeeper reports.

    Inputs to confirm
    Reviewed census data, recordkeeper reports and plan documents.
    Human review
    The responsible administrator signs off before filing.
    Measure
    Plans per administrator during filing season and corrections before filing.

    Why: The brief cites a TPA acquirer saying professionals are retiring in a tight talent market, so output per administrator matters. Diligence risks →

Where AI changes the cost base

AI operating leverage: High. Census cleanup, compliance testing, contribution calculations and Form 5500 preparation are rule-based and make up most of the labor. Our view

  • Most TPA labor sits in plan administrators who collect and clean payroll census data, run nondiscrimination and coverage tests, calculate contributions, and prepare Form 5500 filings. Each of these is a rule-based task driven by IRS and DOL requirements and plan documents.

    Our view

  • A 2026 trade press column said technology and AI will hit TPAs harder in the short term than almost any other part of the DC market. A TPA acquirer quoted in it said the firms that thrive will automate census collection, testing and annual filings.

  • Other document-heavy work includes plan document and amendment drafting, distribution and loan paperwork, and reconciling recordkeeper data with payroll. Acquired TPAs often run different admin software, so moving them onto one platform is a precondition for automation.
