In 60 seconds: For 2026 you can put up to $24,500 of your own pay into a 401(k) — $32,500 if you're 50 or older, and $35,750 at ages 60 to 63. Here's how the limits work, the match mistake that costs people free money, and the new Roth catch-up rule for high earners.
- Your own 2026 limit: $24,500, up $1,000 from 2025 — the same cap covers 401(k), 403(b), most 457(b) plans, and the federal Thrift Savings Plan.
- Age 50 or older: add an $8,000 catch-up, for $32,500 total. Ages 60–63: a bigger $11,250 catch-up, for $35,750 total.
- Counting your employer's match and after-tax contributions, total additions can reach $72,000 — $80,000 at 50+, $83,250 at 60–63.
- The costly mistake: contributing less than the full employer match, or splitting deferrals across two jobs and blowing past the single $24,500 cap.
- New for 2026: high earners above $150,000 in prior-year FICA wages must make catch-up contributions as Roth.

If your retirement plan feels like alphabet soup, you're not alone. Here's the good news: the 2026 numbers are actually simple once you strip out the jargon. The IRS set them in Notice 2025-67, and every figure below comes from that notice, cross-checked across multiple independent summaries.
One honest caveat up front: this is general information, not personal financial advice. Your plan's own rules — and a tax professional — get the final word on your situation.
What happened
Each fall, the IRS reviews the retirement-plan limits for inflation and publishes the next year's figures. For 2026, the headline change is a $1,000 raise: the employee elective-deferral limit rose from $23,500 to $24,500. The age-50 catch-up rose $500, from $7,500 to $8,000, while the special ages-60–63 "super catch-up" held steady at $11,250.
The part people miss: that $24,500 is one cap across all your workplace plans combined. Traditional and Roth 401(k) contributions share it — you don't get $24,500 in each. And contributions to an IRA don't count against it, but switching jobs mid-year doesn't reset it either.
Latest verified facts
| Limit (2026) | 2026 | 2025 |
|---|---|---|
| Your elective deferral (under 50) | $24,500 | $23,500 |
| Catch-up, age 50+ | $8,000 | $7,500 |
| Super catch-up, ages 60–63 | $11,250 | $11,250 |
| Your max total (50+ / 60–63) | $32,500 / $35,750 | $31,000 / $34,750 |
| Total additions (you + employer) | $72,000 | $70,000 |
| Compensation counted for plan formulas | $360,000 | $350,000 |
The other 2026 change worth knowing: under the SECURE 2.0 Roth catch-up mandate, workers whose prior-year FICA wages from the same employer topped $150,000 must make any catch-up contributions as Roth — after-tax now, tax-free later — rather than pre-tax. If that sounds like you, check with your plan administrator before your next payroll change, because not every payroll system flags it automatically.
And here's a number that puts the cap in perspective: maxing $24,500 a year at a 7% return grows to roughly $2.3 million over 30 years, with about $1.6 million of that as growth, not contributions. Time in the plan does the heavy lifting.
Why it matters
Most Americans don't leave retirement money on the table because they're lazy — they leave it because the rules are confusing and the defaults are timid. Two mistakes show up again and again. The first is contributing below the employer match: if your company matches, say, 50 cents per dollar up to 6% of pay, every dollar below that 6% is a 50% instant return you just declined. The second is the job-change trap: defer $14,000 at one employer and $13,500 at the next, and you've put in $27,500 against a $24,500 cap — a $3,000 excess you'll have to unwind, with tax headaches attached.
The catch-ups matter most for late starters. At 50, an extra $8,000 a year is real money; at 60–63, the $11,250 super catch-up is Congress's one acknowledgment that the final working years are when many people can finally afford to save hard.
Impact on the USA and the world
Multiply one worker's limit by tens of millions of participants and you get the scale of it: 401(k)s are the backbone of American retirement saving, and each year's limit bump quietly raises how much of the country's pay can shelter from current tax. For employers, the match is a hiring and retention tool; for the Treasury, the Roth catch-up mandate shifts some tax revenue from retirement into today.
Compared with the accounts we've covered in this series — the Roth IRA's $7,500 limit and the HSA's $4,400 — the 401(k) is simply the biggest lever most workers have, because the employer match stacks on top of your own money. If you have access to all three, the order most planners suggest is: grab the full match first, then the HSA, then max the IRA, then come back to the 401(k).

What happens next
The deadline that matters is December 31, 2026: your elective deferrals generally have to reach your plan through payroll by year-end, so a change made in December only affects your remaining paychecks. If you're under the match, raise your rate now — that's the one move with a guaranteed return. If you changed jobs this year, add up your deferrals across both plans before you max out the second one.
Our take: don't try to hit $24,500 on day one if it breaks your budget. Hit the full match first, then nudge your rate up 1% each quarter. Boring? Sure. But boring is exactly how retirement accounts get big — and the 2026 limits just gave boring a little more room to work.
Frequently asked questions
Can I contribute $24,500 to a 401(k) and $7,500 to an IRA? Yes. The 401(k) and IRA limits are separate — the $24,500 cap covers workplace plans only, so an IRA contribution doesn't reduce it.
Do traditional and Roth 401(k) contributions each get their own limit? No. Pre-tax and designated Roth deferrals share the single $24,500 cap (plus any catch-up you're eligible for).
What happens if I exceed the limit? Tell your plan administrator right away. Excess deferrals generally must be withdrawn and corrected, and they can create extra taxable income if left in place.
Does the $150,000 Roth catch-up rule apply to everyone over 50? No — only to workers whose prior-year FICA wages from the same employer exceeded $150,000. Below that, catch-ups can still be pre-tax if your plan allows.
