What Is The 2025 401(k) Contribution Limit And How Do Catch-Up Contributions Work

The 2025 401(k) elective deferral limit is $23,500, with a standard catch-up contribution of $7,500 for those 50 and older. Starting in 2025, workers ages 60, 61, 62, and 63 get a higher catch-up limit of $11,250 under SECURE 2.0.

What the 2025 401(k) limit actually is

The Internal Revenue Service sets the 2025 401(k) elective deferral limit at $23,500, with a standard catch-up contribution of $7,500 for those 50 and older. That means if you are in that four-year age window, your total employee contribution cap for the year rises to $34,750, while everyone else 50 or older can contribute up to $31,000 total from their own paycheck deferrals. Confirm your plan’s current-year limits directly with your plan administrator or the IRS website before you schedule any contribution change, because the IRS occasionally issues mid-year adjustments and your employer’s plan document controls what is actually available to you.

The base 2025 401(k) contribution limit

For 2025, the Internal Revenue Service raised the elective deferral cap by $500 from the 2024 limit of $23,000. This $23,500 figure applies to employee salary deferrals into a 401(k), 403(b), and most Thrift Savings Plans. It does not include employer matching contributions or profit-sharing contributions, which have a separate combined limit of $70,000 for 2025 (or $77,500 including catch-ups). If you are under 50, $23,500 is the maximum you can personally contribute from your paycheck, even if your plan allows higher percentage deferrals. Go into your payroll portal this week and set your per-paycheck deferral percentage so your total employee contributions land exactly at $23,500 by your final 2025 pay date, not before. Your payroll department will typically stop your contributions automatically once you hit this cap, but you must monitor it yourself if you have multiple jobs with different 401(k) plans. If you hold more than one job with a 401(k), email each plan’s recordkeeper now and request a running contribution total as of your most recent pay period so you can prevent an overcontribution before it happens.

Standard catch-up contributions for age 50 and older

Anyone who turns 50 by the end of the calendar year can make an additional $7,500 in catch-up contributions in 2025, on top of the $23,500 base limit. This brings your total employee deferral to $31,000. The IRS sets the catch-up amount, and it is unchanged from 2024, where it also sat at $7,500. You do not need to meet any income threshold or file a special election, your plan must simply allow catch-up contributions, which most 401(k) plans do. Open your payroll system now and elect the catch-up contribution as a separate deferral line item if your plan requires it; do not assume your regular deferral election automatically covers the extra $7,500. The extra $7,500 is not subject to the $70,000 overall plan limit, so you can combine it with employer contributions without breaking the aggregate cap. If you turn 50 in December 2025, you still qualify for the full $7,500 for that entire tax year, not a prorated amount. Book a 15-minute call with your plan’s recordkeeper before December 1 to confirm your catch-up election is active and will process on your final 2025 paycheck.

The new super catch-up for ages 60 to 63

SECURE 2.0 introduced a higher catch-up limit for a narrowly defined age group: workers who turn 60, 61, 62, or 63 during the 2025 calendar year. For this group, the IRS sets the catch-up contribution at $11,250, making the total elective deferral limit $34,750. This is a $3,750 increase over the standard catch-up amount. The rule is based on your age during the tax year, not the date you make the contribution. For example, if you turn 60 in March 2025 and turn 61 in March 2026, you qualify for the $11,250 catch-up for all of 2025, but in 2026 you will only qualify for the higher amount if you turn 61, 62, or 63 that year. Once you turn 64, you drop back to the standard $7,500 catch-up. The higher limit does not apply to SIMPLE 401(k) plans, which have their own separate catch-up rules. Log into your plan’s recordkeeper site today, navigate to the contribution election screen, and enter $34,750 as your target total employee deferral if you are in the 60-to-63 window; if the system rejects that amount, call the recordkeeper directly and ask them to enable the SECURE 2.0 super catch-up tier on your account.

What people get wrong about catch-up eligibility

The most common mistake is assuming the $11,250 super catch-up applies at age 59½ or after age 65. It does not. The higher limit strictly applies only to the calendar years in which you turn 60, 61, 62, or 63. If you turn 59 in December 2025, you get the standard $7,500 catch-up, not the super amount, even though you might be 59½ by the time you file your taxes. Similarly, if you turn 64 in January 2025, you lose the super catch-up entirely for that year and revert to $7,500. Another frequent error involves rolling over funds: you cannot treat a rollover as a catch-up contribution, and you cannot use the super catch-up to exceed your plan’s actual deferral percentage test limits. The age-based distinction also matters for your retirement accounts more broadly, while the 401(k) rules are age-specific, the difference between a traditional IRA and a Roth IRA involves tax treatment, not contribution timing, so do not confuse the two sets of rules. If you switch jobs mid-year, the catch-up limit applies per person, not per plan, so you must aggregate contributions across all employers. And if you are wondering whether you can roll over my old 401(k) without paying penalties, the answer is yes, a direct rollover to an IRA or new employer plan avoids taxes and penalties, but it does not reset your contribution limits for the year. Finally, if you search online for "the 2025 401(k) contribution limit and how do catch-up contributions work", you will see the same $23,500 and $7,500 figures repeated, but the $11,250 super catch-up is the newest change you need to track.

Frequently Asked Questions

Can I make catch-up contributions if my plan doesn’t offer them?

No. Your 401(k) plan must specifically allow catch-up contributions in its plan document. If it does not, you cannot make them, even if you are over 50. Most large employers offer catch-ups, but you should check your plan’s summary plan description or ask your HR department. Request the summary plan description from your benefits portal this week and search the document for the term “catch-up” to verify eligibility before you adjust any payroll elections.

Do catch-up contributions affect my employer match?

Employer matches are calculated on your contributions, including catch-ups, if the plan defines matching contributions that way. However, many plans cap the match at a percentage of your regular deferral rate, so your catch-up may not increase the match if you already hit the plan’s match cap. Pull your most recent pay stub and compare your year-to-date match received against your plan’s published match formula; if your catch-up contributions are not generating additional match dollars, redirect any unmatched catch-up amount to a Roth IRA first, then return to the 401(k) only after you max out the IRA.

What happens if I contribute too much to my 401(k) in 2025?

Excess deferrals must be withdrawn by April 15, 2026, or you will face double taxation, once in 2025 and again in 2026. The earnings on the excess are also taxable. Your plan administrator will issue a Form 1099-R for the corrective distribution, and you should not count the excess toward your annual limit for the following year. Notify your plan administrator in writing by March 1, 2026 if you discover an overcontribution, and explicitly request a return of excess deferrals plus attributable earnings to meet the April 15 deadline.

Is the super catch-up available for Roth 401(k) contributions?

Yes, but only if your plan allows Roth 401(k) deferrals. The $11,250 super catch-up can be designated as Roth contributions, meaning you pay taxes on that money now but withdraw it tax-free in retirement. The same age and calendar year rules apply regardless of whether you choose pre-tax or Roth treatment. Select the Roth designation inside your contribution election screen when you set the super catch-up amount, and confirm on your next pay stub that the contribution appears under the Roth source column.

The $11,250 super catch-up applies exclusively to the four calendar years in which you turn 60, 61, 62, or 63, and it disappears the moment you enter the year you turn 64, which means your highest-contribution window is temporary and you must act on it during a specific, narrow age band that no other retirement account rule uses.
