SECURE 2.0 Catch-Up Contributions 2026: The $11,250 Roth Mandate High Earners Need to Know

Meet David: $175K Salary, Blindsided by New Rules

David, 58, is a senior engineer at a tech company earning $175,000 per year. For the past 8 years, he's been maxing out his 401(k) contributions, including the $7,500 catch-up contribution for those 50 and older. His strategy has been simple:

• Max out pre-tax 401(k): $23,000 (2025 limit)
• Add catch-up contribution: $7,500 pre-tax
• Total annual contribution: $30,500
• Tax savings: ~$7,320 (24% tax bracket)

In December 2025, David's HR department sent an email with the subject line: "Important: Changes to 401(k) Catch-Up Contributions Starting 2026."

He almost deleted it. Thank goodness he didn't.

The email explained that starting January 1, 2026, because David earned more than $150,000 in 2025, he would be required to make all catch-up contributions to his Roth 401(k) instead of his traditional pre-tax account.

David's reaction: "Wait, they're FORCING me to pay taxes now?"

Yes, David. That's exactly what's happening.

What Is SECURE 2.0?

The SECURE 2.0 Act, signed into law in December 2022, is the most sweeping retirement legislation in decades. It includes over 90 provisions designed to improve retirement security for Americans.

Most of the changes are good:

• Automatic enrollment in 401(k) plans
• Emergency savings accounts linked to retirement plans
• Student loan matching (employers can match student loan payments as 401(k) contributions)
• Enhanced catch-up contributions for ages 60-63

But there's one provision that's causing confusion—and tax headaches—for high earners: mandatory Roth catch-up contributions.

The New Rule: Mandatory Roth Catch-Up for High Earners

Here's the rule in plain English:

Starting January 1, 2026, if you earned more than $150,000 in FICA wages in the previous year (2025) and you're age 50 or older, ALL catch-up contributions to your 401(k), 403(b), or governmental 457(b) plan MUST be made to a Roth account.

According to the IRS final regulations, this is not optional. If your plan offers Roth contributions, high earners must use them for catch-ups. If your plan doesn't offer Roth contributions, high earners cannot make catch-up contributions at all.

Key Details You Must Know:

• Income threshold: $150,000 in FICA wages for 2025 (originally $145,000, increased by IRS on November 13, 2025)
• What counts as FICA wages: W-2 Box 3 wages (Social Security wages)
• Effective date: January 1, 2026 (for calendar-year plans)
• Who it affects: Employees age 50+ by December 31, 2026
• What's impacted: 401(k), 403(b), governmental 457(b) plans (NOT IRAs)
• Grace period for plans: Employers have until December 31, 2026 to implement (for calendar-year plans)

What Are "FICA Wages"?

This is where it gets tricky. The $150,000 threshold is based on FICA wages, not total compensation or adjusted gross income (AGI).

FICA wages include:

• Base salary
• Bonuses
• Commissions
• Taxable fringe benefits

FICA wages DO NOT include:

• Pre-tax 401(k) contributions
• HSA contributions
• Certain fringe benefits
• Qualified transportation benefits

Where to find your FICA wages: Look at Box 3 on your 2025 W-2 (you'll receive it in January 2026).

Real Example: Who's Affected?

Key takeaway: Alice is affected because her FICA wages (after 401(k) deduction) still exceed $150,000. Bob, Carol, and Dan are NOT affected because their FICA wages fall below the threshold, even though their gross salaries are high.

The New Catch-Up Contribution Limits for 2026

According to Charles Schwab's 2026 guide, here are the contribution limits for 2026:

Standard 401(k) Contribution Limits (2026)

• Under age 50: $24,500
• Age 50-59: $24,500 + $7,500 catch-up = $32,000
• Age 60-63: $24,500 + $11,250 super catch-up = $35,750 ⭐
• Age 64+: $24,500 + $7,500 catch-up = $32,000

The "Super Catch-Up" for Ages 60-63

This is one of the positive changes from SECURE 2.0: workers ages 60-63 can contribute an extra $11,250 in catch-up contributions (instead of the usual $7,500).

Why this matters:

• Ages 60-63 are peak earning years for many professionals
• These are the last few years before most people retire at 65-67
• Extra $3,750/year can make a meaningful difference

But here's the catch: If you're a high earner (over $150K FICA wages), that entire $11,250 super catch-up must go into a Roth account.

Roth vs. Traditional: What's the Difference?

If you're not familiar with Roth accounts, here's a quick primer:

Traditional (Pre-Tax) 401(k)

• ✅ Contributions are tax-deductible (you pay less tax now)
• ✅ Money grows tax-deferred
• ❌ Withdrawals in retirement are fully taxed as ordinary income
• ❌ Required Minimum Distributions (RMDs) starting at age 73

Roth 401(k)

• ❌ Contributions are NOT tax-deductible (you pay full tax now)
• ✅ Money grows tax-free
• ✅ Withdrawals in retirement are 100% tax-free (including gains!)
• ✅ Can roll over to Roth IRA (no RMDs)

Which Is Better?

It depends on your tax bracket now vs. your expected tax bracket in retirement.

Traditional is better if:

• You're in a high tax bracket now (32%, 35%, 37%)
• You expect to be in a lower tax bracket in retirement
• You want to maximize current tax savings

Roth is better if:

• You're in a moderate tax bracket now (22%, 24%)
• You expect to be in a higher tax bracket in retirement
• You want tax-free income in retirement
• You want to avoid RMDs

The Tax Hit: Real Numbers

Let's go back to David, our 58-year-old engineer earning $175,000.

Before 2026 (Pre-Tax Catch-Up)

• Gross salary: $175,000
• 401(k) contribution: $24,500 (pre-tax)
• Catch-up contribution: $7,500 (pre-tax)
• Total contribution: $32,000
• Taxable income: $175,000 - $32,000 = $143,000
• Federal tax (24% bracket): ~$21,792

After 2026 (Mandatory Roth Catch-Up)

• Gross salary: $175,000
• 401(k) contribution: $24,500 (pre-tax)
• Catch-up contribution: $7,500 (Roth, not deductible)
• Total contribution: $32,000
• Taxable income: $175,000 - $24,500 = $150,500
• Federal tax (24% bracket): ~$23,592

Difference: David pays $1,800 more in federal taxes in 2026 due to the mandatory Roth catch-up.

But wait, there's a silver lining: That $7,500 Roth contribution will grow tax-free, and David can withdraw it in retirement without paying any taxes on it—including the gains.

Is It Worth It?

Let's assume David contributes $7,500/year to his Roth catch-up from age 58 to 65 (7 years), and it grows at 7% annually.

• Total contributions: $7,500 × 7 = $52,500
• Value at age 65: ~$66,000 (with 7% growth)
• Value at age 85: ~$255,000 (if left untouched)

Tax savings at age 85: If David is in the 24% tax bracket in retirement, he saves $61,200 in taxes by having that $255,000 in a Roth account instead of a traditional account.

Compare that to the $12,600 in extra taxes he paid from ages 58-65 ($1,800/year × 7 years). He comes out $48,600 ahead.

So yes, the mandatory Roth catch-up might actually be a blessing in disguise.

What If Your Plan Doesn't Offer Roth Contributions?

Here's the worst-case scenario: If you're a high earner and your employer's 401(k) plan does not offer Roth contributions, you cannot make catch-up contributions at all starting in 2026.

According to Employee Fiduciary's analysis, this puts pressure on employers to add Roth options to their plans—fast.

What to do if your plan doesn't offer Roth:

1. Talk to your HR department. Ask them to add a Roth option by January 1, 2026 (or ASAP if it's already 2026).
2. Max out your IRA. You can still make catch-up contributions to a traditional or Roth IRA ($8,000 limit for 2026, ages 50+).
3. Open a taxable brokerage account. Not ideal (no tax benefits), but better than nothing.

Strategies to Maximize Your Catch-Up Contributions

If you're a high earner affected by this rule, here are some strategies to consider:

Strategy #1: Stay Just Below the $150,000 FICA Wage Threshold

If you're close to $150,000 in FICA wages, you might be able to reduce your FICA wages by:

• Maxing out your 401(k) contributions ($24,500 in 2026)
• Maxing out your HSA ($8,550 for family coverage in 2026)
• Deferring a year-end bonus into 2026 (if your employer allows it)

Example: Meet Emma, 53

Emma's gross salary is $170,000. Without planning:

• Gross salary: $170,000
• 401(k): $24,500
• FICA wages: $145,500 (below $150K threshold!) ✅

Emma can still make pre-tax catch-up contributions because her FICA wages are below $150,000.

Strategy #2: Embrace the Roth and Plan for Tax-Free Retirement Income

If you're over the $150,000 threshold, lean into the Roth requirement. Think of it as forced tax diversification.

Why this is good:

• You'll have tax-free income in retirement (no RMDs on Roth IRA rollovers)
• Roth withdrawals don't count toward taxation of Social Security benefits
• Hedge against future tax increases
• More flexibility in retirement

Strategy #3: Maximize the Ages 60-63 Super Catch-Up

If you're between 60-63, you can contribute an extra $11,250 per year. Even if it must go into a Roth account, that's a massive opportunity.

Example: Meet Frank, 61

Frank earns $200,000 (well above the $150K threshold). He maxes out his super catch-up:

• Regular 401(k): $24,500 (pre-tax)
• Super catch-up: $11,250 (mandatory Roth)
• Total: $35,750

Over 3 years (ages 61-63), Frank contributes:

• $35,750 × 3 = $107,250
• Of which $33,750 is Roth (tax-free in retirement)

At age 85, that $33,750 in Roth contributions could be worth $200,000+ (tax-free).

Strategy #4: Backdoor Roth IRA Conversions

Even if your 401(k) catch-up is now Roth, you can also do backdoor Roth IRA conversions to build even more tax-free retirement savings.

How it works:

1. Contribute $7,000 to a traditional IRA (or $8,000 if age 50+)
2. Immediately convert it to a Roth IRA
3. Pay taxes on the conversion (if any)
4. Let it grow tax-free

Note: If you have existing pre-tax IRA balances, this strategy is more complicated due to the pro-rata rule. Consult a tax advisor.

What About IRAs? Are They Affected?

Good news: Traditional and Roth IRAs are NOT affected by the SECURE 2.0 mandatory Roth catch-up rule.

According to Fiducient Advisors, the Roth catch-up requirement only impacts employer-sponsored retirement plans (401(k), 403(b), governmental 457(b)).

IRA Contribution Limits for 2026:

• Under age 50: $7,500
• Age 50+: $7,500 + $1,000 catch-up = $8,500

You can still choose between traditional (pre-tax) or Roth IRA contributions, regardless of your income.

Employer Action Required: Amend Your Plan Document

If you're an employer or HR professional, your 401(k) plan must be amended to comply with the new SECURE 2.0 catch-up rules.

According to DHJJ's regulatory update, here's what employers need to do:

1. Add Roth option to your plan (if you don't already have one)
2. Update payroll systems to identify high earners (FICA wages > $150K)
3. Amend plan document by December 31, 2026 (for calendar-year plans)
4. Communicate changes to employees (send email, hold webinars, update FAQ)
5. Test systems to ensure catch-up contributions are properly coded as Roth for high earners

Moore Colson warns that plans not in compliance by December 31, 2026 risk IRS penalties and potential disqualification.

Frequently Asked Questions

Q: Can I make regular 401(k) contributions pre-tax and only the catch-up as Roth?

Yes! If you're a high earner, you can still contribute up to $24,500 (the base limit) as pre-tax or Roth—your choice. Only the catch-up portion ($7,500 or $11,250 if ages 60-63) must be Roth.

Q: What if I turn 50 mid-year? When can I start making catch-up contributions?

You can start making catch-up contributions in the year you turn 50, even if your birthday is in December. The IRS uses "attained age" (age at the end of the calendar year) for catch-up eligibility.

Q: What if my FICA wages are $149,000 in 2025 but $160,000 in 2026?

The rule looks at the previous year's FICA wages. So:

• 2026 catch-up contributions: Based on 2025 FICA wages ($149K) = NOT affected (can do pre-tax)
• 2027 catch-up contributions: Based on 2026 FICA wages ($160K) = Affected (must do Roth)

Q: Can I opt out of catch-up contributions altogether?

Yes, catch-up contributions are always optional. If you don't want to pay the extra taxes from mandatory Roth contributions, you can simply not make catch-up contributions at all. (Though this means you're leaving potential retirement savings on the table.)

Q: Will the $150,000 threshold adjust for inflation?

The law does not specify automatic inflation adjustments for the $150,000 threshold. It may be adjusted by Congress in future legislation, but for now, assume it stays at $150,000.

The Bottom Line: Don't Let This Catch You Off Guard

Here are the three key takeaways:

1. Check your 2025 FICA wages (W-2 Box 3). If you're over $150,000 and age 50+, your catch-up contributions MUST go to Roth in 2026.
2. Confirm your plan offers Roth contributions. If it doesn't, talk to HR immediately. No Roth option = no catch-up contributions for high earners.
3. Plan for the tax hit—but embrace the long-term benefits. Paying taxes now on Roth contributions means tax-free income in retirement. That's a powerful advantage.
