Your 401(k) is probably the most powerful wealth-building tool you will ever own — and the IRS just raised the ceiling on it. For 2026, the contribution limits went up across the board, catch-up contributions for workers over 50 got a bump, and a brand-new rule changes how high earners make catch-up contributions. Whether you're putting in a few percent or trying to max everything out, here is exactly how much you can put in your 401(k) in 2026 — and how to make every dollar count.
The short answer: most workers can contribute up to $24,500 of their own pay in 2026. If you're 50 or older, you can add a $8,000 catch-up for a total of $32,500. And if you turn 60, 61, 62, or 63 this year, a special "super catch-up" lets you defer up to $35,750 from your own paycheck. But the numbers only tell half the story — the order in which you contribute, and where the money lands, matters just as much.
2026 401(k) Limits at a Glance
The IRS announced the 2026 retirement plan limits in Notice 2025-67. Here is the full set in one place:
| Limit | 2026 | 2025 |
|---|---|---|
| Employee elective deferral (your contributions) | $24,500 | $23,500 |
| Catch-up contribution, age 50 and over | $8,000 | $7,500 |
| "Super" catch-up, ages 60–63 | $11,250 | $11,250 |
| Total from all sources (you + employer) | $72,000 | $70,000 |
| Compensation that counts toward contributions | $360,000 | $350,000 |
| Highly compensated employee threshold | $160,000 | $160,000 |
These limits apply to 401(k)s, 403(b)s, most 457 plans, and the federal Thrift Savings Plan (TSP). Note one detail that surprises people: the $24,500 employee limit is per person, not per plan. If you switch jobs mid-year, your contributions at the old job and the new job count toward the same single limit — your new employer's payroll department won't know what you contributed earlier, so track it yourself.
How Much Can You Put In? It Depends on Your Age
Your personal maximum is the employee deferral limit plus whichever catch-up you qualify for:
- Under 50: $24,500 of your own pay.
- Ages 50–59 and 64+: $24,500 + $8,000 catch-up = $32,500.
- Ages 60–63: $24,500 + $11,250 "super catch-up" = $35,750 — the highest deferral in the program's history.
The super catch-up comes from the SECURE 2.0 Act and applies in the calendar years you turn 60, 61, 62, and 63. It replaces the regular $8,000 catch-up for that age group; the two don't stack. At 64, you drop back to the regular catch-up. Before adjusting your payroll election, confirm your plan actually supports the super catch-up — not every plan has set it up yet.
There is also a second ceiling: $72,000 total from all sources in 2026. That covers your contributions, your employer's match, profit-sharing, and any other employer additions combined. Catch-up contributions sit outside this cap, which is how a 55-year-old can effectively reach $80,000 in one year. Only your first $360,000 of earnings count toward percentage-based employer contributions.
The Employer Match: The Free Money Most People Underuse
The contribution limit tells you what you're allowed to put in. The employer match tells you what you'd be crazy to skip. A common match structure is 50 cents on every dollar you contribute, up to 6% of your salary — meaning if you earn $80,000, contributing 6% ($4,800) gets you an extra $2,400 from your employer. That is a 50% instant return before your money has grown a single cent.
Yet surveys consistently find a meaningful share of workers don't contribute enough to capture the full match — effectively leaving part of their compensation unclaimed. Whatever else you do with the 2026 limits, step one is simple: contribute at least enough to get the full match. For most people that means somewhere between 3% and 6% of pay. After that, the question becomes where the next dollar earns the most.

New in 2026: The Roth Catch-Up Rule for High Earners
The biggest rule change this year comes from the SECURE 2.0 Act. Starting in 2026, if your FICA wages from your employer exceeded $150,000 in the prior year (2025), any catch-up contributions you make must go in as Roth (after-tax) contributions — not traditional pre-tax ones.
What does that mean in practice? Your regular $24,500 can still be pre-tax, saving you taxes today. But your $8,000 catch-up (or $11,250 super catch-up) won't reduce this year's taxable income — instead, it grows tax-free and comes out tax-free in retirement. Check Box 3 of your prior-year W-2 to see whether the rule applies to you.
One catch: your plan must offer a Roth 401(k) option for you to make catch-up contributions at all. If your plan doesn't have one, affected high earners above the wage threshold simply can't make catch-ups in 2026 — worth raising with your plan administrator or HR now, not in December.
How Much Should You Actually Contribute?
Knowing the ceiling is different from knowing the right amount. Here's a practical order of operations that works for most US workers in 2026:
- Get the full employer match first. Contribute whatever percentage unlocks 100% of your company's match — usually 3% to 6% of pay.
- Build your emergency fund next — 3 to 6 months of essential expenses in a high-yield savings account — if you haven't already. Investing is hard when a surprise bill forces a withdrawal.
- Consider a Roth IRA (2026 limit: $7,500, plus $1,100 if you're 50+), especially if your 401(k) fund choices are expensive. IRAs often offer cheaper, broader investment options. See How to Start Investing With Just $100 in 2026 for low-cost ways to begin.
- Then come back and push your 401(k) toward the max — aim for $24,500 (plus catch-ups if eligible). A common long-term target is saving 15% of gross income across all accounts, including the match.
A concrete example: earn $70,000 and your employer matches 50% up to 6%. Contributing 6% means $4,200 from you and $2,100 free from your employer each year. Raise that to 15% total ($10,500/year, about $875/month) and you're investing seriously without touching the $24,500 ceiling. The limit gives you headroom — the habit gives you the results.
Mistakes That Cost People Real Money
- Setting your rate once and forgetting it. Many plans default you to 3%. That might miss the full match and will never approach the $24,500 limit. Bump your percentage at least once a year, ideally when you get a raise.
- Forgetting contributions across two jobs. The $24,500 limit follows you, not the plan. Two jobs' contributions add up — overshooting triggers an excess-contribution headache and a correction process.
- Assuming your plan allows everything. Plans can set their own caps below the IRS limits, and some haven't enabled the 60–63 super catch-up or a Roth option. Read your Summary Plan Description.
- Withdrawing early. Money pulled from a 401(k) before age 59½ generally faces income tax plus a 10% early-withdrawal penalty. The limits reward leaving the money alone.
Frequently Asked Questions
How much can I contribute to my 401(k) in 2026?
Up to $24,500 of your own pay. Workers 50 and older can add an $8,000 catch-up ($32,500 total), and workers who turn 60–63 in 2026 get an $11,250 "super catch-up" ($35,750 total). The combined ceiling from you plus your employer is $72,000.
What is the 401(k) catch-up contribution limit for 2026?
$8,000 for participants age 50 and over — up from $7,500 in 2025. Workers ages 60–63 instead get a special $11,250 super catch-up under SECURE 2.0, which replaces the regular catch-up for that age group.
Do employer contributions count toward the $24,500 limit?
No. The $24,500 limit covers only your elective deferrals (traditional pre-tax and Roth combined). Your employer's match goes toward the separate $72,000 total-additions ceiling.
Can I contribute to a 401(k) and an IRA in the same year?
Yes — the limits are independent. You can max your 401(k) at $24,500 and still contribute up to $7,500 to a traditional or Roth IRA in 2026 (plus a $1,100 IRA catch-up if you're 50+), subject to IRA income limits for deductibility and Roth eligibility.
What is the new Roth catch-up rule in 2026?
If your FICA wages from your employer were above $150,000 in 2025, your 2026 catch-up contributions must be Roth (after-tax) rather than pre-tax. Check Box 3 of your 2025 W-2, and make sure your plan offers a Roth option so you can still make catch-ups.
