You've been counting down the years until you turn 50 so you can finally supercharge your retirement savings with catch-up contributions. But if you earn more than $150,000 and your employer's 401(k) doesn't offer a Roth option, 2026 just threw you a curveball: you might not be able to make catch-up contributions at all.

Here's everything you need to know about the new 2026 retirement contribution limits—and the critical SECURE 2.0 rule that could cost high earners thousands in lost retirement savings.

The Good News: 2026 Contribution Limits Are Up

The IRS announced inflation-adjusted increases to retirement contribution limits for 2026, giving savers more room to build their nest eggs:

401(k), 403(b), and 457 Plans:

Base contribution limit: $24,500 (up from $23,500 in 2025)
Catch-up for ages 50+: $8,000 (up from $7,500 in 2025)
Super catch-up for ages 60-63: $11,250 (new for 2026!)
Total maximum for ages 60-63: $35,750

Traditional and Roth IRAs:

Base contribution limit: $7,500 (up from $7,000 in 2025)
Catch-up for ages 50+: $1,100 (up from $1,000 in 2025)
Total maximum ages 50+: $8,600

The "super catch-up" for ages 60-63 is particularly exciting. If you're in that narrow age window, you can now contribute $11,250 extra instead of the standard $8,000—giving you an additional $3,250 per year during those critical pre-retirement years.

The Hidden Catch: SECURE 2.0's Roth Requirement

Here's where things get complicated. Starting in 2026, a provision from the SECURE 2.0 Act of 2022 fundamentally changes the rules for catch-up contributions:

If you earned more than $150,000 in FICA wages the previous year, all catch-up contributions to your 401(k), 403(b), or governmental 457 plan MUST be made as Roth (after-tax) contributions.

Let's break down what this means:

The Income Threshold: This applies to anyone whose prior-year wages subject to Social Security and Medicare taxes (FICA wages) exceeded $150,000. Note that this is not your adjusted gross income (AGI) or modified adjusted gross income (MAGI)—it's specifically your W-2 Box 1 wages.
Roth Only: If you meet that threshold, you cannot make traditional (pre-tax) catch-up contributions. Every dollar of your catch-up must go into the Roth 401(k) portion of your plan.
The Nuclear Option: If your employer's retirement plan doesn't offer a Roth option at all, you're completely blocked from making any catch-up contributions. Zero. Nada.

Why This Is a Bigger Deal Than You Think

For many high earners, this isn't just an inconvenience—it's a potential disaster.

Scenario 1: The Forced Roth Conversion

Let's say you're 52 years old, earn $175,000, and have been planning to contribute the full $32,500 to your 401(k) in 2026 ($24,500 base + $8,000 catch-up). You were counting on that full amount to reduce your taxable income.

Under the new rules:

Your $24,500 base contribution can still be traditional (pre-tax)
Your $8,000 catch-up must be Roth (after-tax)

That $8,000 that used to reduce your taxable income by $8,000 (saving you about $2,640 in federal taxes at the 33% marginal rate) now provides zero tax benefit in the current year. You're paying $2,640 more in taxes than you expected.

Scenario 2: The Complete Lockout

Now imagine your employer's plan simply doesn't offer a Roth 401(k) option. Many older plans don't, especially at smaller companies. In this case, you're completely prohibited from making catch-up contributions.

If you're age 60-63, that's $11,250 of potential retirement savings you simply cannot make. Over four years (ages 60-63), that's $45,000 in lost contribution space—plus all the compound growth those contributions would have generated over the next 20-30 years.

At a conservative 7% annual return over 25 years, that $45,000 would have grown to approximately $244,000. That's real money left on the table.

What You Need to Do Right Now

Don't wait until December to figure this out. Here's your action plan:

Step 1: Check Your 2025 Income

Pull up your most recent pay stub or estimate your 2025 W-2 Box 1 wages. Will you exceed $150,000? Remember, this is wages, not AGI, so it includes your 401(k) contributions.

Step 2: Verify Your Plan Offers Roth

Contact your HR department or 401(k) plan administrator and ask explicitly: "Does our 401(k) plan offer a designated Roth option?" Don't assume—verify.

If your plan doesn't offer Roth, escalate this to leadership immediately. Many employers are scrambling to add Roth options before this rule takes effect, but plan amendments take time.

Step 3: Calculate the Tax Impact

Use our Federal Tax Form calculator to compare two scenarios:

Scenario A: Full traditional contributions (what you're used to)
Scenario B: Base traditional + catch-up Roth (your new reality)

The difference in your tax refund or amount owed could be substantial. You may need to adjust your withholding or estimated tax payments to avoid underpayment penalties.

Step 4: Revisit Your Contribution Strategy

For some high earners, the forced Roth catch-up is actually beneficial. If you're in a high tax bracket now but expect to be in an even higher bracket in retirement (perhaps due to large traditional IRA/401(k) balances triggering huge RMDs), paying taxes now locks in today's rate.

But for others—especially those planning to retire early or move to a no-income-tax state—this forced Roth conversion is a tax hit you don't want.

Consider whether you should:

Max out the catch-up anyway (even as Roth) for the retirement savings benefit
Skip the catch-up and invest in a taxable brokerage account instead
Contribute the catch-up to a Roth IRA if you're under the income limits (though most high earners phase out)

Don't Forget About IRA Limits and Phase-Outs

While 401(k) changes grab headlines, IRA rules matter too. For 2026, the income phase-out ranges have increased:

Roth IRA Contributions:

Single filers: $153,000 - $168,000 (up from $150,000 - $165,000 in 2025)
Married filing jointly: $242,000 - $252,000 (up from $236,000 - $246,000 in 2025)

Traditional IRA Deductions (if covered by workplace plan):

Single filers: $81,000 - $91,000 (up from $79,000 - $89,000 in 2025)
Married filing jointly: $129,000 - $149,000 (up from $126,000 - $146,000 in 2025)

If you're a high earner affected by the 401(k) catch-up rules, you likely don't qualify for Roth IRA contributions or deductible traditional IRA contributions. However, you can still make non-deductible IRA contributions and potentially convert them to Roth through a backdoor Roth IRA strategy (consult a tax professional about the pro-rata rule).

The Super Catch-Up Sweet Spot: Ages 60-63

There is one unequivocally good piece of news in all this: if you're between ages 60 and 63, you qualify for the enhanced catch-up contribution of $11,250 instead of the standard $8,000.

This "super catch-up" recognizes that these pre-retirement years are when many people finally have the financial capacity to save aggressively—kids are through college, mortgage is paid down, income is at its peak.

The extra $3,250 per year might not sound like much, but over four years (ages 60-63) that's an additional $13,000. If you're married and both spouses are in this age range, that's $26,000 in extra retirement savings.

Just remember: if you earned over $150,000 last year, this entire $11,250 catch-up must go into Roth if your plan offers it, or you can't make it at all if your plan doesn't.

Common Questions About the New Rules

Q: What if I earn $145,000 this year but get a bonus that pushes me over $150,000?

A: The $150,000 threshold is based on your prior year's FICA wages. So your 2026 catch-up contributions are determined by what you earned in 2025. If you exceeded $150,000 in 2025, your 2026 catch-ups must be Roth.

Q: Can I make some catch-up contributions as traditional and some as Roth?

A: No. If you're over the $150,000 threshold, the entire catch-up amount must be Roth. You cannot split it.

Q: What about SIMPLE IRAs or SEP IRAs?

A: The Roth requirement only applies to 401(k), 403(b), and governmental 457 plans. SIMPLE IRA catch-up contributions are not affected. (SIMPLE IRAs don't have Roth options anyway.)

Q: Does this affect my spouse's contributions?

A: Each person's catch-up contribution is determined by their own prior-year FICA wages. If you earned $175,000 but your spouse earned $80,000, you must make Roth catch-ups, but your spouse can still make traditional catch-ups.

Why Congress Did This (And Why It's Controversial)

The SECURE 2.0 Act included this provision as a revenue raiser. By forcing high earners to pay taxes now (via Roth contributions) rather than deferring them (via traditional contributions), the government collects tax revenue sooner.

The logic: if you're earning $150,000+, you can afford to pay the taxes now, and you're probably in a high bracket where the tax deferral is most valuable. Making you pay taxes now raises revenue for the Treasury.

The problem: retirement planning isn't one-size-fits-all. Some high earners plan to retire to low-tax states, take early retirement with reduced income, or have other strategies where tax deferral makes more sense than paying taxes upfront.

Critics also point out that the $150,000 threshold isn't indexed for inflation (at least not yet), so over time, more and more middle-income earners will be swept into this requirement.

The Bottom Line: Don't Leave Money on the Table

Whether you love or hate the new catch-up rules, one thing is certain: you need to plan for them.

If you're a high earner approaching age 50 or already making catch-up contributions, take action now:

Verify your plan offers Roth contributions
Calculate the tax impact of forced Roth catch-ups
Adjust your withholding if necessary
Consider whether catch-up contributions still make sense for your situation
If your plan doesn't offer Roth, pressure your employer to add it ASAP
