In 60 seconds: In 2026 you can put up to $24,500 of your own pay into a 401(k) — $32,500 if you're 50 or older, $35,750 if you're 60 to 63 — and the single most expensive mistake is leaving your employer's match on the table.
- The 2026 employee limit is $24,500, up $1,000 from $23,500 in 2025, under IRS Notice 2025-67.
- Age 50+ catch-up: an extra $8,000, for $32,500 total. Ages 60–63: a higher $11,250 catch-up instead, for $35,750 total.
- Your employer's match does NOT count toward your $24,500 — it counts toward the $72,000 combined annual limit.
- Traditional (pre-tax) and Roth 401(k) contributions share ONE $24,500 cap — they don't stack.
- If you change jobs mid-year, your contributions across all plans still share the same cap — payroll systems don't always talk to each other, so track it yourself.
Here's the thing: most Americans with a 401(k) never read the plan documents. They pick a percentage on day one, forget about it, and quietly lose thousands over a career. The 2026 numbers just changed — and this is the year to get the basics right, because the new catch-up rules have a trap in them for higher earners.

What happened
Each fall, the IRS adjusts retirement plan limits for inflation. For 2026, the headline move is a $1,000 rise in the employee elective-deferral limit for 401(k) plans, from $23,500 to $24,500, announced in IRS Notice 2025-67. The same $24,500 figure applies to 403(b) plans, most governmental 457(b) plans, and the federal Thrift Savings Plan.
That sounds like a small tweak. In practice, for someone contributing every paycheck for 30 years, an extra $1,000 a year of tax-advantaged saving — plus whatever it earns — is a serious amount of money. And the catch-up changes for older workers are bigger than the headline suggests.
Latest verified facts
| 2026 limit | 2026 | 2025 (for comparison) |
|---|---|---|
| Employee elective deferral (under 50) | $24,500 | $23,500 |
| Catch-up, age 50+ | +$8,000 → $32,500 | +$7,500 → $31,000 |
| Super catch-up, ages 60–63 | +$11,250 → $35,750 | +$11,250 → $34,750 |
| Total annual additions (you + employer) | $72,000 | $70,000 |
| SIMPLE 401(k) deferral | $17,000 | $16,500 |
Three rules trip people up, so let's get them straight. First, the $24,500 is one bucket: if you split contributions between a traditional pre-tax 401(k) and a Roth 401(k), the two together can't exceed $24,500. Second, your employer's match and profit-sharing sit outside that bucket — they count toward the much larger $72,000 total-additions limit instead. Third, catch-ups are only available if your plan actually offers them, and the 60–63 "super catch-up" replaces the regular $8,000 catch-up — you don't get both.
There's also a new wrinkle for higher earners in 2026. Under the SECURE 2.0 rules, if your prior-year FICA wages were above $150,000 (based on 2025 wages), your catch-up contributions must go in as Roth contributions. If that applies to you and your plan's payroll setup hasn't caught up, check with HR before you assume your catch-up is going in pre-tax.
Why it matters
The match is the whole ballgame for most workers. An employer match is part of your compensation — turning it down by contributing less than the match threshold is like volunteering for a pay cut. Before you worry about fund choices or market timing, make sure you're contributing at least enough to get every dollar of the match, every paycheck. Some plans match per paycheck rather than annually, so dropping your contribution mid-year can quietly cost you match dollars even if your annual total looks fine.
Then there's vesting. Your own contributions are always yours. Employer match money often vests on a schedule — leave too early and you can forfeit part of it. That's worth knowing before you time a job change, not after.
And the job-change trap deserves repeating: the $24,500 cap follows you, not your employer. If you switch jobs in June having already deferred $15,000, your new plan's payroll system won't know that — only $9,500 of headroom remains for the rest of the year, and going over it means an excess deferral that has to be corrected or it gets taxed twice.
Impact on the USA and the world
For American workers, the 2026 limits are a small but real raise in tax-advantaged saving room at a time when Social Security's future is a live debate — which is exactly why personal retirement saving carries more weight than it did a generation ago. The higher catch-ups for workers in their 50s and early 60s are aimed squarely at people with the least time left to save and the most to lose from starting late.
Compared with Canada and Australia, the US system is the outlier: Canada's RRSP and Australia's superannuation are built around different caps and tax treatments, and workers who move between countries often discover their retirement accounts don't travel cleanly. If you've worked abroad, don't assume your US 401(k) rules and your foreign account rules play nicely together — get advice before you roll anything over.

What happens next
Our take: do three things this week. First, log in to your plan and check your current contribution rate against the match threshold — if you're below it, raise it now, not in January. Second, if you're 50 or older, check whether your plan offers catch-ups and whether your payroll is actually applying them. Third, if you changed jobs this year, add up your deferrals across both employers before year-end and fix any excess while there's still time to correct it cleanly.
The IRS will announce 2027 limits next fall, and your plan may change its match formula at year-end — both are worth a five-minute check when they land. But the fundamentals won't change: get the full match, stay inside the cap, and let time do the heavy lifting. That's the boring advice, and it's boring because it works.

Frequently asked questions
How much can I put in my 401(k) in 2026? Up to $24,500 of your own pay if you're under 50, $32,500 if you're 50 or older, and $35,750 if you're 60 to 63 — provided your plan offers catch-up contributions.
Do traditional and Roth 401(k) contributions have separate limits? No. They share one $24,500 employee cap. Splitting between them doesn't double your room.
Does my employer's match count toward the $24,500? No. The match counts toward the $72,000 combined annual-additions limit, not your employee limit.
What if I change jobs mid-year? Your deferrals across all employers still share the same $24,500 cap. Track the total yourself — payroll systems at different companies don't share that data.
Can I also contribute to an IRA in the same year? Yes. The 2026 IRA limit is $7,500, and it doesn't reduce your 401(k) room (SIMPLE IRA rules differ — check your plan).
