Plan Designated Roth Catch-Up Documentation Coordination: A Practical Checklist for Sponsors and TPAs

How plan sponsors, TPAs, and recordkeepers document SECURE 2.0 designated Roth catch-up eligibility, payroll source codes, and HCE compensation evidence—without replacing your recordkeeper platform or counsel.

Operational coordination guidance for plan sponsors, TPAs, and recordkeepers — not ERISA, tax, investment, or legal advice. Work with qualified counsel, your recordkeeper, and plan counsel on substantive plan rules and fiduciary process.

Pair this checklist with Plan catch-up contribution documentation coordination, " ", Plan ADP/ACP testing documentation coordination, " ", Plan elective deferral change documentation coordination, " ", Plan sponsor benefits document accountability, " ", Needs Attention dashboards for financial ops for a full sponsor operations mesh.

Designated Roth catch-up rules add a compensation threshold, payroll source coding, and participant communication layers on top of ordinary catch-up deferrals. When sponsors, TPAs, recordkeepers, and payroll each maintain different census extracts and deferral flags, proving who was eligible—and that Roth catch-up dollars posted to the correct source—becomes an audit headache.

This article is operational coordination guidance, not ERISA, tax, investment, or legal advice. Work with qualified counsel, your recordkeeper, and compliance vendors on statutory requirements, plan amendments, and participant notices. Use this checklist to standardize intake, HCE determination evidence, payroll mapping, and escalation across sponsor HR, payroll, TPA operations, and recordkeeper teams.

Why designated Roth catch-up workflows stall

Common patterns:

  • Compensation definition drift — payroll “wages” differ from plan compensation used for HCE thresholds
  • Source-code errors — catch-up deferrals post to pre-tax or an incorrect Roth sub-account
  • Timing gaps — eligibility changes mid-year without updated elections or payroll effective dates
  • Testing blind spots — ADP/ACP or top-heavy workflows not refreshed when Roth catch-up volume shifts
  • Notice versioning — participant education materials not tied to the plan amendment or SECURE 2.0 effective dates your counsel approved

A workflow control layer does not replace your recordkeeper, payroll systems, or ERISA counsel. It answers: who must use designated Roth catch-up, when payroll may take the election, and where the evidence lives.

Designated Roth catch-up document checklist

1. Intake and plan design snapshot

  • Named sponsor, TPA, recordkeeper, payroll, and counsel owners for Roth catch-up cycles
  • Plan document and amendment references for designated Roth catch-up availability
  • HCE compensation definition documented with data source and refresh cadence
  • Related workflows flagged (catch-up contributions, elective deferral changes, ADP/ACP testing, automatic enrollment)

2. Eligibility and participant communication

  • Prior-year compensation or current-year projection used consistently for threshold tests (per counsel direction)
  • Participant elections or confirmations captured before payroll changes (portal, form, or recorded verbal policy per sponsor rules)
  • Notices and education materials versioned when rules or amendments change
  • Exceptions (union, excluded classes, plans without Roth deferrals) documented with approver

3. Payroll and recordkeeper alignment

  • Roth catch-up source codes mapped in payroll with effective dates and stop rules
  • Recordkeeper deferral confirmation reconciled to payroll after first impacted pay period
  • Year-to-date deferral totals monitored when participants approach statutory limits
  • Corrections routed to corrective distribution workflow when mis-postings are identified

4. Ongoing monitoring

  • Mid-year hires, promotions, and rehires re-tested for HCE status before Roth catch-up elections propagate
  • Testing cycles receive updated deferral files when Roth catch-up volume shifts
  • Match or profit-sharing true-ups flagged when Roth deferrals affect employer formulas

5. Closeout and audit trail

  • Plan year marked complete with archived compensation reports and election files
  • Supporting documents indexed (not scattered across email threads)
  • Lessons learned captured when threshold or source-code disputes required rework
