The 2026 401(k) Contribution Limits

Your personal ceiling depends on your age. The base employee deferral is the same for everyone, but the catch-up you can add on top — and the combined employee-plus-employer total — changes once you hit 50, and again for the four years you’re 60 to 63.

Read it across your row: the “your max” column is what you can put in from your own paycheck, and the final column is the total once your employer’s match and any profit-sharing are added. These limits apply to 401(k), 403(b), governmental 457(b), and the federal Thrift Savings Plan.

Quick Answers to the Top Questions

What’s the 2026 401(k) limit?

$24,500 in employee elective deferrals, up $1,000 from the 2025 limit of $23,500. That’s the cap on what you contribute from your own salary before any employer money.

How much can I add over 50?

An extra $8,000 standard catch-up, bringing your personal total to $32,500. See the super catch-up if you’ll be 60 to 63.

What’s the super catch-up?

For ages 60–63 only, the catch-up jumps to $11,250 instead of $8,000 — a personal max of $35,750. More below.

What’s the new Roth rule?

If your 2025 wages from your employer topped $150,000, all of your catch-up contributions must be Roth in 2026. This is the big change.

Did the limit go up?

Yes. The base rose by $1,000 to $24,500. The standard catch-up rose $500 to $8,000; the super catch-up held at $11,250.

What’s New for 2026? (Three Key Changes)

Three things changed worth knowing before you set your elections:

1. The base limit rose to $24,500. A $1,000 increase over 2025 gives every saver a bit more room.
2. The super catch-up stays at $11,250 for ages 60–63. Combined with the higher base, that’s a $35,750 personal ceiling — the most you can contribute from your own pay at any age.
3. The Roth catch-up mandate takes effect. High earners can no longer make pre-tax catch-up contributions. If your 2025 employer wages exceeded $150,000, every catch-up dollar in 2026 must be Roth.

The Super Catch-Up for Ages 60–63

This is the most generous window the tax code offers a retirement saver. In the calendar years you turn 60, 61, 62, or 63, your catch-up rises from $8,000 to $11,250, pushing your personal maximum to $35,750 for 2026.

The key detail people miss is that it’s a four-year window, not a permanent step up. The moment you turn 64, your catch-up reverts to the standard $8,000, and your personal max drops back to $32,500. So if you’re in or approaching that band and can afford it, the planning angle is simple: max it aggressively while the window is open.

Two caveats. First, your plan has to actually offer the super catch-up — most large plans do, but confirm with your administrator. Second, the super catch-up is still a catch-up, which means the new Roth rule applies to it: a high earner using the super catch-up must route that $11,250 into Roth dollars.

The New Roth Catch-Up Rule for High Earners

This is the rule that will surprise the most people in 2026. Under the SECURE 2.0 Act, if your prior-year wages from your employer were high enough, you lose the choice to make pre-tax catch-up contributions — they must be Roth.

Who’s affected

The trigger is more than $150,000 in 2025 FICA (Social Security) wages from the employer that sponsors your plan. A few precise points:

• It’s based on prior-year wages (2025), not your 2026 income.
• It’s measured per employer. Wages from the employer whose plan you’re in are what count, so changing jobs can change your status.
• It uses your FICA wages — roughly your Social Security wage base figure — not your total or adjusted gross income.
• The $150,000 figure is indexed for inflation; it rose from $145,000 and will continue to adjust over time.

The surprising part: no Roth option means no catch-up

If your plan doesn’t offer a Roth 401(k) feature and you’re over the wage threshold, the rule doesn’t quietly let you make a pre-tax catch-up instead — it means you can’t make a catch-up contribution at all until the plan adds Roth. That’s a real risk for older high earners at smaller employers whose plans never adopted a Roth source.

What to do

• Confirm your plan offers a Roth 401(k) source. If you’re over the threshold and it doesn’t, raise it with HR now.
• Check your elections. Some payroll systems will auto-redirect catch-up to Roth; others won’t. Make sure your catch-up is correctly designated.
• Plan for the cash-flow hit. Roth contributions are after-tax, so the same catch-up costs you more in take-home terms. Budget for it.

One practical note: final regulations gave plans an administrative transition period, with plan-amendment deadlines extending into late 2026, so exact timing can vary by employer. Confirm how and when your specific plan is applying the rule.

Why Are High Earners Pushed Into Roth? (And Is It Bad?)

The logic is about timing tax revenue. A pre-tax catch-up gives you a deduction today; forcing high earners into Roth means the government collects that tax now rather than decades later. For higher-income workers — who get the largest dollar benefit from a deduction — that’s where the most revenue sits.

But here’s the honest trade-off: it isn’t necessarily bad for you. You lose the upfront deduction, yes. In exchange you get tax-free growth and tax-free withdrawals in retirement, and — thanks to a separate SECURE 2.0 change — Roth 401(k) balances no longer face required minimum distributions during your lifetime, the way pre-tax balances do.

For someone who expects to be in a similar or higher tax bracket later, or who wants tax diversification and a cleaner estate, mandatory Roth can be a feature, not a bug. Whether pre-tax or Roth wins for you comes down to your bracket now versus later — the same question covered in Roth vs. traditional. High earners weighing Roth conversions should also watch the income thresholds in the 2026 IRMAA brackets, since extra taxable income can raise Medicare premiums.

High Earners, Roth IRAs & the Backdoor Roth

The Roth catch-up mandate applies to employer plans only — your 401(k), 403(b), or 457(b). It does not touch IRAs. But high earners hit a different wall with Roth IRAs: income limits.

For 2026, your ability to contribute directly to a Roth IRA phases out at these MAGI ranges:

• Single / head of household: $153,000 to $168,000 (no direct contribution above $168,000).
• Married filing jointly: $242,000 to $252,000 (no direct contribution above $252,000).

Above those ceilings, the backdoor Roth is still allowed in 2026: you contribute to a traditional IRA (no income limit on the contribution itself) and convert it to Roth. There’s no current legislation eliminating it. Two things to watch: the pro-rata rule, which can make the conversion partly taxable if you hold other pre-tax IRA money, and the mega backdoor Roth — making after-tax 401(k) contributions and converting them — which depends entirely on whether your plan allows after-tax contributions and in-plan conversions.

2026 Limits by Account Type

The 401(k) gets the headlines, but the IRS adjusted nearly every retirement account for 2026. Here’s the full picture.

Self-employed? The solo 401(k) often lets you contribute far more than a SEP at the same income, because you can add both employee deferrals and employer profit-sharing.

How Much Should You Actually Contribute?

Maxing out isn’t always the first move. A sensible order of operations for 2026:

1. Capture the full employer match first. If your employer matches up to 5% and you contribute less, you’re leaving free money on the table — that’s an instant, guaranteed return no investment can promise.
2. Then work toward the $24,500 base. Even a one- or two-percent bump in your deferral rate compounds meaningfully over a career.
3. Mind the combined cap. Employee plus employer contributions can’t exceed $72,000 (under 50), $80,000 (50–59 and 64+), or $83,250 (60–63) for 2026.
4. Balance Roth and pre-tax. If you’re not forced into Roth, split based on whether you expect higher or lower taxes later. Many savers hold some of each for flexibility.

Not sure where you stand? Compare against average retirement savings by age, and if you’re nearing retirement, think about how contributions fit into broader retirement income planning.

Common 401(k) Mistakes to Avoid in 2026

• Leaving the match on the table. Contributing below your match rate is the single most expensive 401(k) mistake — and the easiest to fix.
• Being a high earner who never checks for a Roth option. If you’re over $150,000 in 2025 wages and your plan has no Roth source, you may be unable to make any catch-up at all. Confirm before you assume.
• Missing the 60–63 super catch-up window. Those four years allow $35,750 of personal contributions; once you turn 64 the chance is gone.
• Over-contributing across multiple employers. The $24,500 employee limit is per person, not per plan. If you switched jobs or run two plans, your deferrals across all of them count toward the same cap.

Frequently Asked Questions

What is the 401(k) contribution limit for 2026?

$24,500 in employee elective deferrals for those under 50, up from $23,500 in 2025. Employer contributions are on top of this.

How much can I contribute to my 401(k) over 50 in 2026?

$32,500 if you’re 50–59 or 64 and older (the $24,500 base plus an $8,000 catch-up), and $35,750 if you’re 60–63 (base plus the $11,250 super catch-up).

What is the super catch-up contribution for 2026?

An enhanced catch-up of $11,250 — instead of $8,000 — available only in the years you’re 60, 61, 62, or 63. It raises your personal max to $35,750. At 64 it reverts to $8,000.

Does the catch-up have to be Roth for high earners?

Yes. Starting in 2026, if your prior-year (2025) wages from your employer exceeded $150,000, any catch-up contributions must be designated Roth (after-tax).

What income makes my catch-up Roth-only?

More than $150,000 in 2025 FICA (Social Security) wages from the employer sponsoring your plan. It’s measured per employer and based on the prior year, not your total household income.

What if my plan doesn’t offer a Roth option?

If you’re over the wage threshold and your plan has no Roth 401(k) source, you cannot make catch-up contributions at all until the plan adds one. Ask your administrator whether Roth is available.

Is the backdoor Roth still allowed in 2026?

Yes. There’s no law eliminating it. You contribute to a traditional IRA and convert to Roth. Watch the pro-rata rule if you hold other pre-tax IRA balances.

Can I contribute to a Roth IRA if I make over $200,000?

It depends on filing status. A single filer’s direct contribution phases out by $168,000, so at $200,000 you can’t contribute directly. Married filing jointly phases out between $242,000 and $252,000, so at $200,000 a joint filer can still contribute fully. Above the limit, use the backdoor Roth.

Did the 401(k) limit go up for 2026?

Yes, by $1,000 — from $23,500 to $24,500. The standard catch-up also rose $500 to $8,000, while the super catch-up held at $11,250.

What’s the total I can put in a 401(k) in 2026?

Counting employer contributions, the combined cap is $72,000 if you’re under 50, $80,000 if you’re 50–59 or 64+, and $83,250 if you’re 60–63.
