2026 Contribution Limits by Age
| Age Group | Base Limit | Catch-Up | Total Limit |
|---|---|---|---|
| Under 50 | $24,500 | None | $24,500 |
| 50–59 | $24,500 | $8,000 | $32,500 |
| 60–63 | $24,500 | $11,250 | $35,750 |
| 64+ | $24,500 | $8,000 | $32,500 |
These figures are the employee elective deferral limits. A separate, much higher combined limit of $72,000 (employee + employer contributions) applies to total plan contributions, including employer match and profit-sharing. These are 2026 figures as published by the IRS at the time this page was last reviewed — the IRS updates contribution and catch-up limits annually, and your specific plan may have additional rules, so always verify the current-year figure at irs.gov before finalizing a contribution decision.

How Catch-Up Contributions Work
The IRS allows workers age 50 and older to contribute extra, on top of the standard elective deferral limit, to help make up for years they may not have maxed out earlier in their career. Starting at age 60 through age 63, the IRS provides an even higher catch-up amount than the standard age-50 catch-up; once you turn 64, the standard age-50 catch-up amount applies again. This "enhanced" catch-up window for ages 60–63 is a relatively new feature of federal retirement law, so it's worth double-checking your plan actually supports it — not every plan is required to offer it in every year.
Some higher-earning participants may be required to make their catch-up contributions as Roth (after-tax) rather than pre-tax, depending on prior-year wages — a plan-specific and income-specific rule that changed in recent years. Check with your plan administrator if this could apply to you.
Two Worked Examples
| Scenario | Limit | Catch-Up Included | Remaining Room |
|---|---|---|---|
| Age 45, contributed $10,000 so far | $24,500 | None (under 50) | $14,500 |
| Age 52, contributed $15,000 so far | $32,500 | $8,000 (standard catch-up) | $17,500 |
| Age 61, contributed $20,000 so far | $35,750 | $11,250 (age 60–63 catch-up) | $15,750 |
Notice the 61-year-old has more total room than the 52-year-old, purely because of the higher age 60–63 catch-up tier — timing your extra contributions to land inside that window, if you're able to, captures meaningfully more tax-advantaged space.
Why This Matters More Than It Looks
It's a Use-It-or-Lose-It Window
Unused contribution room from one year doesn't carry over to the next — if you have the ability to contribute more before the calendar year ends, that opportunity closes on December 31.
Payroll Timing Matters
Because contributions come out of paychecks, hitting the limit precisely requires coordinating your per-paycheck contribution rate with your remaining pay periods in the year — talk to your payroll or benefits team if you're trying to max out.
Plan Rules Can Be Stricter
Some plans cap your contribution rate as a percentage of pay regardless of the IRS dollar limit, which can make it mathematically impossible to reach the full IRS limit through payroll alone for very high earners.
Why Limits Are Indexed Rather Than Fixed
The IRS adjusts most retirement plan contribution limits periodically to account for cost-of-living changes, rather than leaving them fixed indefinitely — this is why the limit this year may differ from the limit last year or next year, and why a calculator (including this one) needs a visible review date rather than a permanently "correct" number. Bookmarking the IRS's own contribution-topics page, rather than memorizing a single figure, is the most reliable way to stay current.
What If You Max Out Your 401(k)?
Hitting your full 401(k) contribution limit is a good problem to have, and it's worth knowing your options don't stop there. Common next steps people consider, in no particular order: an Individual Retirement Account (Traditional or Roth IRA, which has its own separate and much lower annual limit set by the IRS), a Health Savings Account if you have an eligible high-deductible health plan (which offers its own distinct tax advantages and limit), or simply investing in a regular taxable brokerage account, which has no contribution limit at all but doesn't carry the same tax advantages. Each of these has its own eligibility rules and annual limit, set and updated separately by the IRS — this calculator only covers the 401(k) elective deferral limit.
A Note on "Mega Backdoor" and After-Tax Contributions
Some 401(k) plans allow after-tax contributions beyond the standard elective deferral limit, up to the higher combined employee-plus-employer limit — sometimes paired with an in-plan conversion feature, a strategy often referred to informally as a "mega backdoor Roth." Not all plans offer this, the rules are plan-specific, and the tax treatment can be complex. If your plan document mentions after-tax contributions or in-plan Roth conversions and you're interested, that's a conversation worth having with your plan administrator or a tax professional rather than assuming it works the same way everywhere.
Frequently Asked Questions
What is the 401(k) elective deferral limit?
The elective deferral limit is the maximum amount you personally can contribute from your own paycheck in a given year, set annually by the IRS. It does not include employer match, which falls under a separate, higher combined limit.
How does the age 60–63 catch-up work?
The IRS provides a higher catch-up contribution amount specifically for participants who are age 60 to 63 in a given year — larger than the standard age 50+ catch-up. Once you turn 64, the standard age-50 catch-up amount applies instead. Verify current-year figures directly with the IRS, since these are indexed and can change annually.
Do contribution limits apply per person or per plan?
The elective deferral limit generally applies per person across all 401(k) plans you contribute to in a calendar year, not per employer — if you changed jobs mid-year and contributed to two different 401(k) plans, your combined contributions across both still count toward the same annual limit.
What happens if I accidentally over-contribute?
Excess contributions generally need to be corrected, often by withdrawing the excess amount plus any earnings before the tax filing deadline, to avoid additional tax consequences. Contact your plan administrator promptly if you believe you've over-contributed.
Does the combined limit include employer match?
Yes. The IRS sets a separate, much higher combined limit that includes your own elective deferrals plus employer match and any other employer contributions, such as profit-sharing.
Are Roth 401(k) contributions counted the same as Traditional?
Yes, for the elective deferral limit. Roth and Traditional 401(k) contributions share the same annual limit; if you split contributions between the two, they add up together against the same cap.
