As of Jan. 1, 2026, SECURE 2.0 introduced significant changes to Roth catch‑up contributions. Here’s a look at what that means.
As of Jan. 1, 2026, SECURE 2.0 introduced significant changes to Roth catch‑up contributions.
While the Roth catch‑up mandate may initially look like a payroll or recordkeeping issue, its effects reach well beyond administration. The change introduces real compliance considerations and can alter how defined contribution allocations are structured. For participants age 50+ whose prior‑year FICA wages exceed the applicable threshold, catch‑up dollars must now be made as Roth. The requirement was originally set for 2024 but was delayed to 2026 to allow time for implementation.
Who’s Affected?
There’s been a lot of talk about the Roth catchup requirement, but as a reminder the following are key points regarding which plan participants are affected:
- Threshold: Prior-year FICA wages over $150,000 (indexed annually from $145,000).
- Catch-Up Limits: $8,000 in 2026 (or up to $11,250 for ages 60–63).
- Exemptions: Self-employed individuals aren’t subject to this because they don’t have FICA wages. Therefore some HCEs/key employees may fall below the threshold.
- Plan Limitation: If the plan doesn’t offer Roth, impacted participants simply lose the ability to make catch-up contributions.
Much has been made of how the requirement affects employee contributions, but little attention has been devoted to how it interacts with the IRS annual addition limit.
How Does This Interact with 415(c)?
Catch-up contributions don’t count toward the annual additions limit under Internal Revenue Code (IRC) Section 415(c) ($70,000 in 2025; $72,000 in 2026). Under Treas. Reg. §1.414(v)-1(b), catch-up treatment applies when a participant exceeds an applicable limit, whether that’s a statutory limit such as that under IRC Section 415(c), an employer-imposed cap or an ADP limit.
Opportunity: If a participant defers less than the limit under IRC 402(g) ($23,500 in 2025; $24,500 in 2026), they can still treat additional deferrals (up to the catch-up limit) as catch-up contributions to maximize the IRC 415(c) allocation.
Example: A 51-year-old earning $350,000 defers $10,000 in 2025. The participant could still receive a $67,500 profit-sharing allocation, triggering $7,500 of that deferral to be treated as catch-up. This approach has been confirmed by IRS representatives as allowable, but it’s still subject to 401(a)(4) and deduction limits. So if the client also has a defined benefit plan to contribute to, it might need to be PBGC covered for this to work, otherwise the client would be subject to the 404(a)(7) limit which could limit the ability to use this approach. The plan would also need to have demographics to allow it to pass testing with the maximum defined contribution allocation.
What Changes Were Made in 2026?
If catch-up contributions are recharacterized under IRC 415(c) and the participant is subject to the Roth requirement, any pre-tax deferrals must be converted to Roth. That means potential tax consequences for the participant. Going forward, you should either:
1. Avoid maxing out the 415(c) limit if doing so would trigger catch-up reclassification for participants who:
ad space
- Have deferrals below the 402(g) limit,
- Are subject to the Roth requirement,
- And have not deferred at least the portion being reclassified as catch-up on an after-tax Roth basis.
OR
2. Discuss with the client in advance to confirm whether the impacted participant wants to:
- Maximize 415(c) and trigger catch-up reclassification,
- Understanding that the reclassified portion must be converted to Roth and will therefore be taxable.
Correction Options for Misclassified Pre-Tax Catch-Up
If pre‑tax deferrals fall under the Roth requirement, they must be reclassified and converted to Roth. The final regulations issued in September 2025 outline the available correction methods.
- W-2 Correction: Must occur before W-2 issuance, which is rarely practical for 415(c)-triggered corrections.
- In-Plan Roth Rollover: Move the deferral plus earnings to Roth; participant receives 1099. Taxable to the participant in the rollover year, not the deferral year.
- Deadline: End of the year following the deferral to avoid qualification failure.
Compliance Pitfalls
The Roth catch up requirement can also create potential nondiscrimination challenges.
- The FICA threshold is lower than the HCE threshold, so some NHCEs could be subject to Roth while some HCEs aren’t. If the plan lacks Roth, this creates a potential benefit rights and features nondiscrimination failure.
- Final regs address this and provide relief if catch-up is prohibited for HCEs with self-employment income, but the cleanest solution in most cases would be to amend the 401(k) to add Roth as soon as possible.
Key Takeaways for Practitioners
The Roth catch‑up mandate carries wider implications than many of us on the DB side may have expected. It doesn’t just affect participant taxation — it also has ripple effects on plan compliance and the mechanics of defined contribution allocations.
So if you’re an actuary who assumed this requirement wouldn’t affect your work, it’s definitely worth a closer look.
In practice, helping clients navigate these changes means taking a few proactive steps, including encouraging them to amend their plans to add Roth deferrals as soon as possible and flagging situations in which an IRC 415(c) maximum allocation could cause pre‑tax deferrals below the 402(g) limit to be treated as catch‑up — ultimately triggering the Roth requirement and the associated taxation.
