2026 401(k) Contribution Limit: What Changed This Year

Short version: the 2026 401(k) employee deferral limit is $24,500, up from $23,500 in 2025. If you're 50 or older, you can stack a catch-up contribution on top of that base number, and if you're turning 60 to 63 this year, the catch-up gets a further boost. There's also a new SECURE 2.0 wrinkle that pushes some higher earners into Roth catch-up contributions whether they want them or not. Here's what actually changed, what it means in dollars, and how it plays out depending on your age.

What Is the 2026 401(k) Contribution Limit?

The IRS publishes three separate numbers every year, and confusing them is where most people get tripped up. The one everyone means by "the 401(k) limit" is the employee elective deferral limit — the cap on what comes straight out of your paycheck. For 2026, that's $24,500 per IRS guidance.

If you're 50 or older, you're not stuck at that number. You can add a catch-up contribution of $8,000 on top of the standard deferral limit, per IRS guidance on catch-up contributions. It's extra room, not a swap. The base limit still applies in full; the catch-up just sits on top of it.

Then there's the number nobody thinks about until a plan administrator brings it up: the combined employer-plus-employee cap under IRC Section 415(c). For 2026, everything landing in your account from every source — your own deferrals, employer match, profit-sharing, all of it — tops out at the lesser of 100% of compensation or $72,000, per IRS guidance.

The distinction is worth sitting with. Your $24,500 is what you control from a paycheck. The $72,000 is a ceiling on the whole account, including money you never touch because your employer put it there. Most workers never come close to that combined cap. People with a rich match, a profit-sharing plan, or a side business running its own retirement plan sometimes do.

2026 vs. 2025: How Much More Can You Contribute?

The increases are modest but real. The employee elective deferral limit moves to $24,500 for 2026, up from $23,500 in 2025 per IRS Publication 560. For a saver 50 or over who isn't yet in the 60-63 enhanced catch-up window, the combined deferral-plus-catch-up total climbs to $32,500 in 2026, up from $31,000 in 2025 — both from IRS Publication 560.

The combined employer-plus-employee 415(c) cap moved too: $72,000 for 2026 versus $70,000 in 2025 per IRS guidance.

• 2026 elective deferral: $24,500 — 2025: $23,500
• 2026 age 50+ combined total: $32,500 — 2025: $31,000
• 2026 combined 415(c) cap: $72,000 — 2025: $70,000

None of this happens by legislative whim. These numbers tend to move a bit most years, sometimes more, sometimes less. Some years the bump is bigger, some years the IRS holds a number where it was. The size of any given year's increase is not decided in advance.

Three Savers, Three Totals: A 2026 Contribution Scenario

The numbers land differently depending on where you sit in your career. Here's how 2026 plays out for three savers at different ages.

• Under 50: The standard elective deferral limit applies, no catch-up available. Maxing out means $24,500 for the year per IRS guidance.
• Age 55: The standard age 50+ catch-up of $8,000 stacks on the $24,500 deferral limit, per IRS guidance. Combined, total possible employee contributions reach $32,500 for the year, per IRS Publication 560.
• Age 62: This is who SECURE 2.0's enhanced catch-up was built for. Ages 60 through 63 get a bigger "super catch-up" of $11,250 instead of the standard $8,000, per IRS guidance. That $11,250 stacks on the same $24,500 base everyone else uses.

Line these up against your own birthday and the picture sharpens fast. A 62-year-old has meaningfully more room than a 55-year-old, who has more room than someone in their thirties. Honestly, most people underestimate how much that four-year window from 60 to 63 is worth. It's narrow, and once it closes, the enhanced catch-up drops back to the standard amount.

Who Does the New Roth Catch-Up Rule Affect?

Buried in SECURE 2.0 is a rule that changes how catch-up contributions get taxed for some higher earners, and it takes effect for 2026. If your prior-year FICA wages exceeded $150,000, per IRS guidance, your catch-up contributions have to go in as Roth — after-tax — instead of pre-tax.

A few things worth sitting with. The $150,000 threshold looks at wages from the prior year, not the current one. It only touches the catch-up slice of your contributions; the base $24,500 elective deferral is unaffected no matter your income. And it's a mandate on tax treatment, not a cap on the amount — the dollar limits themselves, $8,000 standard and $11,250 for ages 60-63, stay exactly the same.

For the fuller picture on how catch-up rules interact across account types, our breakdown of catch-up contribution limits by account goes deeper. The short version here: paying tax now instead of later on that slice of savings is a real shift for anyone above the wage line, and it's worth understanding before payroll makes the decision for you.

2026 Limits at a Glance: FAQ

Does the combined cap include employer matching and profit-sharing? Yes. The $72,000 combined 415(c) limit for 2026 covers your own deferrals plus employer contributions of every kind — match, profit-sharing, all of it — per IRS guidance. It's a ceiling on the whole account, not just what you personally put in.

How does the 401(k) limit compare to the 2026 IRA limit? The IRA contribution limit for 2026 is $7,500, combined across traditional and Roth IRAs, per IRS guidance. That's well below the 401(k)'s $24,500, which is one reason people who can swing it tend to max the 401(k) first. For the full rundown, see our 2026 IRA contribution limit guide and our comparison of 401(k) vs. IRA basics.

Do catch-up contributions get added automatically, or is it a separate election? Catch-up amounts are extra room on top of the standard deferral limit, not something that shows up on its own. Whether you actually reach the catch-up range depends entirely on how much you elect to defer from each paycheck.
