SECURE 2.0 Roth Catch-Up Contributions: What Changed and Who It Affects

TL;DR

• Implementation begins January 1, 2026, after an IRS-issued transition delay under Notice 2023-62.
• Applies to employees age 50+ whose prior-year FICA wages from their current employer exceeded USD 150k.
• Does not apply to partners with K-1 income, independent contractors, or recent job changers who lack prior-year wages at their new firm.

SECURE 2.0 Roth catch-up contributions are now mandatory for specific high-earning employees starting January 1st of 2026. The rule requires workers age 50 and older — whose prior-year FICA wages from their current employer exceeded USD 150k — to make all catch-up contributions on an after-tax Roth basis instead of pre-tax. Not everyone is impacted. Most employees will notice nothing.

The rule covers 401(k) and 403(b) as well as governmental 457(b) plans. It is triggered by Box 3 W-2 wages from a specific employer — not by the adjusted gross income or total household income. If you are wondering whether this applies to your distinct scenario, the answer depends on three things: 

• your age
• your catch-up election
• where your wages came from last year

What SECURE 2.0 changed for catch-up contributions

Before SECURE 2.0, every participant age 50 or older could direct catch-up contributions to a pre-tax account. Section 603 of the Act ended that option for high-income participants. The mechanics shifted — but only for a defined subset.

The original effective date was 2024. IRS Notice 2023-62 granted a 2-year administrative transition period and moved implementation to taxable years beginning after December 31st of 2025. In other words, January 1st of2026 is the real, final deadline.

The 2026 standard catch-up limit for participants age 50 and older is USD 8k. A separate SECURE 2.0 provision also created a "super catch-up" limit of USD 11,250 for participants aged 60 through 63 — and if those employees also clear the wage threshold, that higher amount must also go in as Roth.

Who must make SECURE 2.0 roth catch-up contributions in 2026?

Specific 3 conditions must be satisfied at the same time: 

• the employee must be age 50 or older
• currently making catch-up contributions
• must have earned more than USD 150k in FICA wages from the employer sponsoring the plan in the prior year

Miss any one of them, and the mandate does not apply.

The USD 150k FICA Wage Threshold Explained

The IRS is not looking at the MAGI. It is not looking at the total taxable income. It is specifically testing the prior-year Box 3 W-2 wages from the employer currently sponsoring your plan — and the total household AGI is completely irrelevant. Only local payroll is important.

Section 414(v)(7)(A) originally set a 145k dollar figure, but cost‑of‑living adjustments have set the Roth catch‑up wage threshold used for 2026 at 150k dollars, based on 2025 FICA wages. Many competitors still quote USD 145k. That figure is outdated and will misdirect employees who are right at the boundary.

Think of it like a VIP club card. The USD 150k threshold is VIP status at a specific venue. Switch clubs — change jobs — and the new venue has no record of what you spent at the old one. Your prior-year wages only count if they were earned at the same employer who is now sponsoring your 401(k).

Exemptions — Job Changers, Partners and Non-FICA Earners

The IRS "camera" only checks your speed on this specific road — your current employer's payroll. If your only prior-year income was from a different, unrelated job or from K-1 distributions with no FICA wages from the employer sponsoring your plan, the Roth mandate will not apply to you.

Exempt categories include: 

• partners receiving K-1 income
• self-employed individuals with self-employment income
• state or local government employees not covered under Social Security
• employees who changed jobs and simply have no prior-year FICA wages at their new firm

No wages, no test.

An example scenario: 

David earns USD 200k total. 

Of that, USD 80k is K-1 partnership income and USD 120k is W-2 FICA wages from his employer. Because his FICA wages fall below the USD 150k threshold, David is exempt from the mandatory Roth catch-up requirement.

Multiple employer situations obtain the same logic. Wages across different employers are never aggregated. If you earned USD 100k at Job A and USD 120k at Job B last year, neither W-2 independently exceeded the threshold. No mandate applies at either employer.

Do you have to make catch-up contributions as Roth?

Which employer plans are impacted?

The mandate covers 401(k) and 403(b) as well as governmental 457(b) plans. Private-sector 457(b) plans fall outside the scope of SECURE 2.0's Roth catch-up rules. The plan type should be confirmed before adjusting any elections.

What Happens if Your Plan Lacks a Roth Option?

If the plan does not permit designated Roth contributions, no one can make catch-up contributions at all. Zero. The restriction applies regardless of income, age, or how long the employee has been with the firm.

The employer must amend the plan to add a Roth feature before any participant above the standard limit can contribute further. The plan amendment deadline for most standard plans is December 31st of 2026 — collectively bargained and governmental plans have extended deadlines.

Timing and deadlines — when does this start?

January 1, 2026. That is the date. IRS Notice 2023-62 pushed the original 2024 implementation back by 2 years. No further extensions have been issued and none are anticipated.

Employees near the threshold need to review their deferral elections before the plan year opens. Payroll systems need to be configured to classify catch-up contributions as Roth for affected participants. Waiting until Q2 to sort this out creates downstream recordkeeping problems.

Are Roth catch-up contributions a good idea?

Roth contributions are made with after-tax dollars — you give up the current-year deduction. In exchange, qualified distributions can be tax-free if statutory conditions are fulfilled. Whether that trade is advantageous depends entirely on the individual.

The relevant variables are your current marginal rate, your projected bracket in retirement, your state of residency, and whether your cash flow can absorb the loss of a pre-tax deduction now. There is no single correct answer.

SECURE 2.0 Roth catch-up contributions vs Roth IRA rules

These are two separate systems operating under different statutes. The SECURE 2.0 catch-up rules apply only inside employer-sponsored plans. Roth IRA eligibility is governed by MAGI phaseout limits and earned income requirements — not by what happens in your 401(k).

There is no age restriction on Roth IRA contributions under current law. As long as you have earned income at or above the contribution amount and remain below the applicable MAGI phaseout, you can contribute to a Roth IRA at age 70, 75, or beyond. The employer plan mandate changes none of that.

SECURE 2.0 Roth catch-up FAQs

Can I still contribute to a Roth IRA after age 70?

Yes. There is no age limit for Roth IRA contributions under current law — IRS Publication 590-A. The only requirements are earned income at least equal to the contribution amount and compliance with the applicable MAGI phaseout limits. SECURE 2.0 employer plan rules do not change Roth IRA eligibility.

Are Roth catch-up contributions a good idea?

That depends on the current marginal tax rate vs your expected rate in retirement, your state's tax treatment of retirement income, and your cash flow during the contribution years. A CPA review of your individual situation is the only reliable basis for this decision.

Alexander Accountants can review your 2026 elections before they take effect

If your W-2 wages are anywhere near the USD 150k line, the 2026 plan year will arrive before most employees notice the impact on their paycheck. 

Pre-tax catch-up deferrals that have run on autopilot for years may no longer be available to you — and discovering that mid-year creates payroll corrections, amended filings, and avoidable stress.

Alexander Accountants works with high-income professionals and business owners to review deferral strategies ahead of the plan year — not after the fact. 

Contact us to confirm whether the USD 150k FICA wage threshold applies to your situation, whether your employer's plan is properly amended, and how to align your 2026 elections with the actual tax position.
