SECURE 2.0 Roth Catch-Up Mandate in 2026: A Complete Guide for High Earners
Beginning January 1, 2026, 401(k), 403(b), and governmental 457(b) participants age 50 or older who earned more than $150,000 in prior-year FICA wages (Box 3 of Form W-2) from their plan-sponsoring employer must make all catch-up contributions on a Roth (after-tax) basis. IRS Notice 2025-67 officially adjusted this statutory threshold from the initial $145,000 projection to $150,000 for 2026. Self-employed partners and individuals with lower per-employer W-2 wages remain exempt from the mandatory Roth rule.

1. What SECURE 2.0 Section 603 Actually Requires
Direct Answer: SECURE 2.0 Act Section 603 amended Internal Revenue Code §414(v)(7) to mandate that all catch-up contributions made by retirement plan participants age 50 and older whose prior-year FICA wages exceed $150,000 must be designated as Roth (after-tax) contributions starting in 2026.
Under traditional 401(k), 403(b), and governmental 457(b) retirement plans, eligible workers age 50+ could choose whether to allocate their extra catch-up contributions on a pre-tax or Roth basis. SECURE 2.0 Section 603 fundamentally altered this flexibility for high-income earners to generate near-term federal tax revenue.
The $145,000 to $150,000 Statutory Correction via IRS Notice 2025-67
When Congress passed SECURE 2.0 in late 2022, the statutory text established a base wage threshold of $145,000 for the 2023 tax year, indexed for inflation in subsequent years. Because IRS Administrative Notice 2023-62 delayed mandatory implementation to 2026, many financial articles and obsolete calculators still incorrectly display the outdated $145,000 threshold.
On November 13, 2025, the Internal Revenue Service released IRS Notice 2025-67, officially confirming the cost-of-living index adjustment for 2026. The statutory threshold was formally set at $150,000 in prior-year FICA wages. Taxpayers relying on guidance citing $145,000 risk miscalculating their catch-up eligibility and contribution tax designations.
2026 Administrative Grace Period vs. 2027 Final Regulations
Following the release of the Treasury Department's Final Regulations on Catch-Up Contributions (TD 10012, published September 16, 2025), the IRS established an operational transition framework. For plan years beginning in 2026, plan sponsors are held to a good-faith compliance standard. Full operational enforcement—including strict plan document amendment deadlines and automated payroll blocking—becomes mandatory for plan years beginning on or after January 1, 2027.
2. The Per-Employer Wage Test: Why Aggregation Isn't Automatic
Direct Answer: The $150,000 wage threshold under IRC §414(v)(7) is tested on a per-employer basis using Box 3 Social Security wages from the specific employer sponsoring the plan. Wages earned from unrelated employers—or separate corporate entities—are NOT aggregated by default.
A common misconception among dual-income individuals and multi-job professionals is that overall gross income or household W-2 wages dictate the Roth mandate. The statute explicitly ties the test to FICA wages (IRC §3121(a)) paid by the employer maintaining the retirement plan during the preceding calendar year.
Consider a 54-year-old executive who earns $100,000 from Parent Corp and $100,000 from Subsidiary Corp in 2025. Both companies participate in a single 401(k) master plan.
- Parent Corp 2025 Box 3 FICA Wages: $100,000 (≤ $150,000 threshold)
- Subsidiary Corp 2025 Box 3 FICA Wages: $100,000 (≤ $150,000 threshold)
- Combined Total Household W-2 Wages: $200,000
- Default Per-Employer Statutory Result: EXEMPT FROM ROTH MANDATE. The employee may elect 100% pre-tax catch-up contributions for 2026.
- Employer Aggregation Result (If Elected by Plan Sponsor): MANDATORY ROTH. If the employer formally elected controlled group wage aggregation, the $200,000 combined wage forces all catch-up contributions into Roth.
When Employer Aggregation IS Applicable
Under the Treasury Final Regulations, an employer may affirmatively elect to aggregate FICA wages across related corporate entities ONLY under three specific statutory arrangements:
- Controlled Groups of Corporations (IRC §414(b)/(c)): Parent-subsidiary or brother-sister corporate groups operating a unified payroll system.
- Common Paymaster Arrangements (IRC §3121(s)): Where a designated paymaster issues a single combined W-2 on behalf of multiple related entities.
- Predecessor & Successor Employer Relationships: Corporate mergers, stock transactions, or asset acquisitions occurring during the prior tax year.
3. The Self-Employment Exception: Partners & Sole Proprietors
Direct Answer: Partners in partnerships, LLC members, and sole proprietors who receive self-employment income (Schedule K-1 / SECA) but NO Form W-2 FICA wages from the plan sponsor are completely exempt from the SECURE 2.0 Roth catch-up mandate regardless of their income level.
This represents one of the most critical structural exemptions in retirement tax policy. Congress drafted IRC §414(v)(7)(A) by referencing FICA wages under Section 3121(a) rather than net earnings from self-employment under Section 1402(a).
Consequently, a equity partner in a law firm, accounting practice, or medical group who earns $1,500,000 in partnership net profits but receives $0 in Box 3 W-2 FICA wages is statutorily exempt from the mandatory Roth requirement. They retain the legal right to make 100% pre-tax catch-up contributions into their Solo 401(k) or partnership retirement plan for 2026.
4. Super Catch-Up (Ages 60–63): Stacking Rules and 2026 Limits
Direct Answer: SECURE 2.0 §109 created an enhanced "Super Catch-Up" limit of $11,250 for participants ages 60, 61, 62, and 63 in 2026. If a participant in this age bracket earned over $150,000 in prior-year FICA wages, the Roth mandate applies to the ENTIRE $11,250 catch-up amount.
For the 2026 tax year, retirement contribution limits under IRS Notice 2025-67 are structured as follows:
| Contribution Category | Standard Age (Under 50) | Standard Catch-Up (50–59, 64+) | Super Catch-Up (Ages 60–63) |
|---|---|---|---|
| Standard Elective Deferral Limit | $24,500 | $24,500 | $24,500 |
| Maximum Catch-Up Allowance | $0 | $8,000 | $11,250 |
| Total Combined 401(k) Deferral Capacity | $24,500 | $32,500 | $35,750 |
Universal Availability Rule Notice: Super catch-up is an optional plan feature. However, under ERISA universal availability mandates, if a plan sponsor offers super catch-up to one non-bargained employee, it must offer it to all eligible participants in the plan. High earners in the 60–63 bracket who cross the $150,000 threshold must fund the full $11,250 via Roth contributions—they cannot split it into pre-tax and Roth.
5. What Happens If Your Plan Doesn't Offer a Roth Feature?
Direct Answer: If a 401(k) or 403(b) plan does NOT maintain an active Roth elective contribution feature, high earners earning over $150,000 are completely prohibited from making ANY catch-up contributions under IRC §414(v)(7)(B).
This requirement is colloquially known as the "No-Roth Plan Trap." Congress designed Section 603 such that if a high earner is required to make catch-up contributions in Roth format, but the plan sponsor fails to provide a Roth account feature, the employee cannot fall back to pre-tax catch-up.
If your employer earned revenue over $150,000 per high earner but has delayed amending its plan documents to add Roth 401(k) accounts, you will lose up to $8,000 (or $11,250 if age 60–63) in annual retirement tax shelter capacity until the plan sponsor completes the Roth amendment.
6. Take-Home Pay Impact: Pre-Tax vs. Roth Paycheck Comparison
Direct Answer: Switching a catch-up contribution from pre-tax to Roth does not change the amount deposited into your 401(k), but it reduces current take-home pay by an amount equal to the catch-up contribution multiplied by your marginal federal and state tax rates.
Paycheck Reduction Matrix at 24%, 32%, and 37% Marginal Tax Rates
| Catch-Up Tier | Contribution Amount | 24% Bracket Hit | 32% Bracket Hit | 37% Bracket Hit |
|---|---|---|---|---|
| Standard Catch-Up (Ages 50–59, 64+) | $8,000 | -$1,920 / yr | -$2,560 / yr | -$2,960 / yr |
| Super Catch-Up (Ages 60–63) | $11,250 | -$2,700 / yr | -$3,600 / yr | -$4,163 / yr |
*Note: State and local income taxes will further increase the immediate take-home pay reduction. However, all future investment growth and qualified withdrawals in retirement are 100% tax-free.
7. IRS Notice 2025-67 & The $150,000 FICA Wage Lookback Threshold
Direct Answer: IRS Notice 2025-67 officially established $150,000 as the prior-year FICA wage lookback threshold for the 2026 tax year, adjusting the initial statutory baseline of $145,000 for inflation. The mandate is tested strictly using Box 3 (Social Security wages) or Box 5 (Medicare wages) from the participant's prior-year (2025) W-2 issued by their current plan-sponsoring employer.
The SECURE 2.0 Section 603 Roth mandate is governed by a strict prior-year lookback mechanism. Rather than testing current-year earnings as they accrue during 2026, the Internal Revenue Code requires plan sponsors to examine the participant's prior calendar year (2025) Form W-2 FICA wages. Specifically, the test evaluates Box 3 (Social Security wages) under IRC §3121(a), or Box 5 (Medicare wages) in cases where Social Security wages are capped or exempt.
A critical practical implication of this lookback structure is that current-year income spikes do not trigger the mandate retroactively. For example, if an employee earns $140,000 in 2025 but receives a massive promotion or performance bonus in mid-2026 pushing their 2026 earnings to $220,000, they remain 100% exempt from the mandatory Roth catch-up rule throughout the entire 2026 plan year. Their 2026 catch-up contributions may be made on a pre-tax basis. The elevated 2026 income will only trigger the Roth mandate for the subsequent 2027 plan year.
Consider a senior manager whose Form W-2 Box 3 FICA wages progress as follows over three tax years:
- 2024 W-2 FICA Wages: $148,000 (≤ $145k COLA threshold for 2025) → 2025 Status: EXEMPT (Pre-tax catch-up permitted).
- 2025 W-2 FICA Wages: $155,000 (> $150,000 IRS Notice 2025-67 threshold) → 2026 Status: MANDATORY ROTH (100% catch-up must be Roth).
- 2026 W-2 FICA Wages: Projected $170,000 → 2027 Status: MANDATORY ROTH (Sustained high earner mandate).
2026 Roth Catch-Up Threshold Determinations
| Employment Scenario | Prior-Year (2025) W-2 FICA Wages | 2026 Mandate Status | Catch-Up Contribution Options |
|---|---|---|---|
| Standard Wage Earner | ≤ $150,000 | Exempt | Participant choice: 100% Pre-Tax, 100% Roth, or Split |
| High Earner W-2 Employee | > $150,000 | Mandatory Roth | 100% Roth Catch-Up Required (Pre-tax barred) |
| New Hire (Hired in 2026) | $0 (No W-2 from current employer) | Exempt for 2026 | Pre-Tax or Roth allowed (Previous employer W-2 ignored) |
8. Section 109 "Super Catch-Up" Mechanics for Ages 60–63
Direct Answer: SECURE 2.0 Act §109 introduced an elevated "Super Catch-Up" limit of $11,250 for participants who reach age 60, 61, 62, or 63 during the 2026 plan year. If a participant in this age window earned over $150,000 in prior-year FICA wages, their entire $11,250 super catch-up must be contributed on a Roth basis.
The interaction between SECURE 2.0 §109 and §603 creates a multi-tiered retirement contribution framework for 2026. Under the statute, standard 401(k), 403(b), and 457(b) elective deferrals are capped at $24,500. Participants age 50 to 59, or age 64 and older, receive a standard catch-up allowance of $8,000 (bringing total deferral capacity to $32,500).
However, for participants turning age 60, 61, 62, or 63 in 2026, Section 109 elevates the catch-up limit to the greater of $10,000 or 150% of the standard catch-up limit ($8,000 × 150% = $11,250). When combined with the $24,500 base deferral, a 61-year-old participant can defer up to $35,750 in total elective employee contributions in 2026.
For high-earning executives in the 32%, 35%, or 37% federal marginal tax brackets, forcing an $11,250 super catch-up into Roth format creates a significant net paycheck impact. In the 32% marginal bracket, making an $11,250 Roth super catch-up contribution requires paying $3,600 in immediate federal income taxes ($11,250 × 32%), directly reducing net take-home pay compared to traditional pre-tax deferral.
Under SECURE 2.0 §109, the Super Catch-Up limit of $11,250 applies strictly to ages 60, 61, 62, and 63. Once an employee turns 64, their maximum allowable catch-up contribution drops back down to the standard tier ($8,000 for 2026). If their prior-year W-2 FICA wages exceeded $150,000, this lower $8,000 catch-up amount remains subject to the mandatory Roth rule.
9. The Self-Employment & Partner Exemption: IRC §414(v)(7)(A)
Direct Answer: Sole proprietors, equity partners in partnerships, and LLC members who receive self-employment income (Schedule K-1) subject to SECA tax are statutorily exempt from the SECURE 2.0 Roth catch-up mandate because IRC §414(v)(7)(A) defines high earner status strictly by FICA wages paid under Section 3121(a).
The statutory drafting of Section 603 created a notable structural distinction between W-2 corporate employees and self-employed business owners. Internal Revenue Code §414(v)(7)(A) dictates that the $150,000 lookback threshold applies exclusively to individuals who received "wages (as defined in section 3121(a)) from the employer sponsoring the plan."
Because partners in law firms, accounting practices, hedge funds, and medical partnerships receive self-employment net earnings governed by SECA tax (IRC §1402(a)) rather than FICA wages under IRC §3121(a), they have $0 in Box 3 W-2 FICA wages from the partnership.
Consequently, a senior equity partner who earns $2,500,000 in annual Schedule K-1 net partnership profit is legally exempt from the mandatory Roth catch-up rule. They may continue making 100% pre-tax catch-up contributions into their firm 401(k) or Solo 401(k) plan for 2026. By contrast, an S-Corporation owner-employee who pays themselves a $160,000 W-2 salary DOES receive FICA wages exceeding $150,000 and MUST make all catch-up contributions on a Roth basis.
10. Employer Aggregation & Common Paymaster Rules
Direct Answer: The $150,000 FICA wage threshold is applied on a per-employer basis. Income from unrelated employers is not combined, but wages across affiliated corporate entities must be aggregated if the entities constitute a controlled group under IRC §414(b)/(c) or operate a common paymaster under IRC §3121(s).
Under standard statutory testing rules, if a participant works for two completely unrelated companies (e.g., Company A during the day and Company B at night) and earns $100,000 from Company A and $100,000 from Company B ($200,000 total income), neither employer paid more than $150,000 in prior-year FICA wages. Neither plan sponsor is required to enforce the mandatory Roth rule.
However, Treasury Department Final Regulations (TD 10012) mandate wage aggregation across corporate boundaries under three specific statutory arrangements:
- Controlled Groups (IRC §414(b) & (c)): Parent-subsidiary and brother-sister corporate groups operating under common ownership must combine prior-year FICA wages across all group entities.
- Common Paymaster Arrangements (IRC §3121(s)): Where a designated paymaster issues W-2s on behalf of multiple related corporations, wages are combined into a single aggregated total.
- Predecessor & Successor Employers: In corporate mergers, stock sales, or asset acquisitions, the acquiring employer must count FICA wages paid by the predecessor entity during the prior lookback year.
11. The IRC §414(v)(7)(B) "No-Roth" Plan Penalty & Administrative Burden
Direct Answer: Under IRC §414(v)(7)(B), if a retirement plan does not maintain an active Roth elective contribution feature, NO participant in the plan—regardless of their individual wage level—is permitted to make catch-up contributions if any participant earning over $150,000 is subject to the mandate.
Congress enacted IRC §414(v)(7)(B) as an enforcement mechanism to prevent plan sponsors from bypassing the Roth mandate by refusing to offer Roth accounts. The statutory text establishes an all-or-nothing rule: if an employer employs even a single worker earning over $150,000 in FICA wages, but the plan document does not contain a Roth provision, all catch-up contributions are prohibited for the entire plan.
This requirement imposes a substantial administrative burden on small-to-midsize business plan sponsors and legacy 403(b) tax-sheltered annuity plans that have historically offered only traditional pre-tax accounts. To comply before the end of the 2026 transition grace period, employers must execute formal plan amendments, update automated payroll deduction engines, reconfigure TPA software, and issue updated Summary Plan Descriptions (SPDs) to participants to avoid plan disqualification.
