Final SECURE 2.0 Roth Catch-Up Rules: Your Payroll Compliance Checklist

Last Updated on March 2, 2026 by VantagePoint

As we move further into 2026, employers and plan administrators face an important compliance priority: final regulations now require certain catch-up contributions under the SECURE 2.0 Act to be made as Roth, meaning after tax, representing a significant shift for many retirement plans.

If you’re responsible for payroll, benefits, or retirement plans for your company, now is the time to act. Below is a practical “what to do before first paychecks of 2026” checklist.

What just changed? Quick recap of the new rules

• Participants who are age 50 or older and whose prior‑calendar‑year Social Security wages (W‑2 Box 3) from the employer exceed the indexed threshold (initially $145,000) must have any catch‑up contributions designated as Roth (after‑tax); pre‑tax catch‑up contributions are not permitted for those participants. 
• The $145,000 figure is the statutory starting point and is indexed for inflation beginning in 2026; plan administrators should use the IRS‑published indexed amount each year.
• This requirement applies to 401(k), 403(b), and governmental 457(b) plans that permit catch‑up contributions; it does not apply to plans that do not permit catch‑ups (unless amended).
  
• If a plan does not permit Roth contributions currently, the employer faces a choice:
  
  1. Amend the plan to allow Roth contributions (thus preserving catch-up eligibility for high earners). If amending, document the amendment and confirm recordkeeper mapping; aim to adopt and operationalize the Roth feature before the first 2026 payroll to avoid rejected deferrals.; OR
  2. Disallow catch‑up contributions for affected participants effective for contributions made on or after January 1, 2026 (unless the plan is amended to permit Roth catch‑ups).

The final regulations explain operational options and timing for plan amendments and administrative implementation; employers should coordinate amendments with their recordkeeper/TPA.

There is also a “super catch-up” option: plans may allow (at the employer’s discretion) higher catch-up limits for participants aged 60–63 (for 2025, the limit is $11,250 instead of the standard $7,500), but the Roth-only rule still applies for high earners. 

Plans may permit an increased ‘super catch‑up’ for ages 60–63 (statutory formula yields $11,250 for 2025 in many summaries); however, any catch‑up made by a participant who meets the Roth threshold must still be designated Roth. Confirm exact annual amounts and indexing with IRS/plan documents.

Why this matters now

• Many companies update retirement/benefits plans at year’s end. This change must be baked in ahead of 2026 contributions.
  
• Payroll systems, recordkeepers, TPAs, and HR teams need to align on how to track wages, spot high earners, and route catch-up contributions as Roth.
  
• Without action, high-earner employees may be unable to make catch-up contributions, or worse, contributions may be rejected because of incorrect code type (pre-tax instead of Roth).
  

Who is impacted and how to identify them

• Participants age 50+ whose prior‑calendar‑year Social Security wages (W‑2 Box 3) from the employer exceed the indexed threshold (initially $145,000), taking into account any controlled‑group/paymaster aggregation election
  
• Employees whose earnings cross the threshold mid-year. The payroll system needs to detect this and flip catch-up contributions to Roth accordingly.
  
• Multi-employer or controlled-group employers: final regulations allow (optionally) aggregation of wages across related entities or paymasters, which may affect who counts as “high earner.”
  

Checklist for identification:

• Pull last year’s W-2 Box 3 (Social Security wages) for all employees age 50+.
  
• Flag everyone above the threshold and mark them “Roth catch-up required.”
  
• Share the flagged list with payroll provider, recordkeeper/TPA, and HR.

How should employers prepare for the new SECURE 2.0 Roth Catch-Up Rules

Payroll & Systems Readiness

• Ensure payroll systems can read prior-year wages and auto-flag high earners.
  
• Confirm there is a separate “Roth catch-up contribution” deduction code (or equivalent), not mixing pre-tax vs Roth.
  
• If your plan covers multiple entities under a controlled group, decide whether to aggregate wages (if the plan allows).
  

Plan Document & Recordkeeper. TPA Alignment

• Review plan documents. If you currently only allow pre-tax catch-up, you must amend the plan to permit Roth catch-up or else prevent high-earner catch-up altogether.
  
• If adopting, confirm with your recordkeeper / TPA that the Roth option is enabled and properly mapped.
  
• Decide if you’ll adopt a “deemed Roth election” (automatic) or require an affirmative Roth election from employees. Final regulations permit automatic (but participants must be given an opt-out).

Communications & Employee Notifications

• Prepare communications for employees age 50+, especially those likely to be identified as high earners, explaining the change, what it means (Roth vs pre-tax), and what they need to do.
  
• Update any salary deferral or enrollment forms to clearly mark Roth catch-up contributions.
  
• For employees near threshold or with variable compensation, remind them that mid-year earnings changes may trigger the Roth requirement.

Key Risks if You Don’t Act

• Catch-up contributions from high earners are being rejected or returned due to incorrect tax treatment.
  
• Employees age 50+ losing catch-up eligibility if the plan is not updated, leading to dissatisfaction or potential legal exposure.
  
• Administrative mess: corrections, recharacterizations, audit risk, and employee confusion.
  
• Damage to the employer’s credibility and benefits program, especially for senior employees relying on catch-up for retirement savings.

Don’t Wait, Act Now

The final SECURE 2.0 Roth catch-up regulations are here, and the compliance deadline is real. If you manage or advise employer-sponsored retirement plans, now is the time to act. Audit your data, coordinate with payroll and recordkeepers, update plan documents, and communicate with employees.

Starting in 2026, catch-up contributions for many high-earner employees will no longer be afforded the pre-tax deduction, only Roth after-tax. Getting ahead now avoids headaches, rejections, and unhappy staff down the line.
