401(k) Contribution Limits for 2026: What They Are and How to Hit Them

The IRS adjusts 401(k) contribution limits most years, and 2026 brought another increase. If you’re trying to figure out how much you can put in, whether your employer’s match counts toward the limit, or how to actually hit the maximum on a normal income — this guide covers all of it in plain English.

The numbers matter. Contribution limits determine how much tax-advantaged retirement money you can build. But knowing the limits is only useful if you also know how to put them to work.

Let’s start with the numbers, then talk about what they actually mean for your paycheck.

The 2026 401(k) Contribution Limits

For 2026, the employee contribution limit for a 401(k) is $24,500. This is up from $23,500 in 2025 — a $1,000 increase. This limit applies to traditional 401(k) plans, Roth 401(k) plans, and 403(b) plans for most employees. The $24,500 limit for 2026 also applies to most participants in 403(b) plans, governmental 457 plans, and the federal Thrift Savings Plan. It does not apply to SIMPLE plans, which have their own lower limits for 2026: $17,000, or $18,100 for certain applicable plans, with catch-up amounts of $4,000 or $5,250 respectively. If you have a SIMPLE plan, do not use the $24,500 figure — you would over-defer.

For 2026, the overall limit on annual additions to a 401(k) plan is the lesser of $72,000 (up from $70,000 in 2025) or 100% of your compensation from that employer. This overall limit is separate from your $24,500 personal contribution limit. It counts your elective deferrals (not including catch-up contributions), employer matching contributions, employer nonelective contributions, and allocations of forfeitures. It applies per employer — across all plans maintained by that employer and any related employer — not as a single per-person cap across unrelated employers. Because catch-up contributions do not count toward this overall limit, the actual total can reach $80,000 if you are eligible for the age-50 catch-up, and up to $83,250 if you are eligible for the higher ages 60-63 catch-up. One more limit matters for high earners: for 2026, the amount of your compensation that can be taken into account when calculating contributions is capped at $360,000. That means matching and other contribution calculations stop at $360,000 of pay, even if you earn more.

Official 2026 limits: IRS IR-2025-111 and IRS Notice 2025-67.

If you’re age 50 or older, you can make catch-up contributions on top of the standard limit. The catch-up amount for 2026 is $8,000, bringing your personal max to $32,500. Workers ages 60 to 63 get an even higher catch-up contribution of $11,250 for 2026, bringing their total elective-deferral limit to $35,750.

New for 2026 — mandatory Roth catch-ups for higher earners: if your 2025 wages from the employer sponsoring your plan exceeded $150,000, any catch-up contributions you make in 2026 must be designated as Roth (after-tax) contributions. You cannot choose to make those catch-up contributions pre-tax. This rule comes from SECURE 2.0 and the final regulations announced in IRS IR-2025-91, using the $150,000 threshold set in Notice 2025-67. It also means a plan without a Roth feature cannot take pre-tax catch-up contributions from participants affected by this rule.

These IRS limits are maximums, not guarantees. Catch-up contributions are available only if your plan permits them, and eligibility is based on your age at the end of the calendar year — you must be age 50 or over by December 31. Your plan may also set a lower deferral limit than the IRS maximum, so check your plan{RSQ}s terms. The higher $11,250 catch-up applies only in the years you attain age 60, 61, 62, or 63; from age 64, the standard $8,000 catch-up amount applies again.

A note for self-employed readers: this post does not cover one-participant (solo) 401(k) plans in full. One distinction matters here: while your personal elective-deferral limit applies across all your plans combined, the overall annual-additions limit applies to each plan separately. That means a self-employed reader may be able to make an employer (nonelective) contribution under a separate, unrelated solo 401(k) plan even after maxing out deferrals at a day-job employer{RSQ}s plan. Check the rules for your own situation before acting, because the employer-contribution calculation for the self-employed involves steps this post does not cover.

These limits apply per person, per year. If you have multiple 401(k) accounts — say, you changed jobs mid-year — the limit still applies across all accounts combined, not per account.

Does Your Employer Match Count Toward the Limit?

This is one of the most common points of confusion. Your employer’s matching contributions do not count toward your $24,500 personal limit. They count toward the $72,000 combined limit.

What this means practically: if your employer matches 4% of your salary and you earn $60,000, your employer contributes $2,400 on top of whatever you put in. You can still contribute the full $24,500 yourself without worrying that the match is eating into your personal limit.

The lesson: always contribute at least enough to get the full employer match. If your employer matches 50% of contributions up to 6% of salary, and you’re only contributing 3%, you’re leaving money on the table — specifically, you’re leaving free matching dollars unclaimed. That’s the highest guaranteed return available to most workers.

How to Hit the 401(k) Limit on a Regular Income

$24,500 sounds like a lot. Divided across 26 biweekly paychecks, maxing out a 401(k) costs roughly $942 per paycheck. On a $52,000 salary, that’s just over 47% of each gross check — which is simply not realistic for most people.

The good news: you don’t need to max out to benefit significantly. For people who aren’t close to maxing, here is a sensible order to work through:

Level 1 — The floor: Contribute enough to get the full employer match. If your employer matches 100% up to 3% of salary, contribute at least 3%. This is non-negotiable — it’s part of your compensation package. If you’re new to investing and want to start with a small amount outside your 401(k), see our guide on how to invest $500 as a beginner.

Level 2 — The next step: After getting the match, consider maxing a Roth IRA before contributing more to your 401(k) (if your income qualifies). Roth IRA contributions are made with after-tax dollars. Earnings can come out tax-free only when the distribution is a qualified distribution that meets the applicable holding-period and event conditions — not on every withdrawal. For 2026, the Roth IRA income phase-out ranges are $153,000 to $168,000 if you file as single or head of household, and $242,000 to $252,000 if you are married filing jointly. For married filing separately, the range is $0 to $10,000. Use these ranges to check whether you qualify to contribute directly to a Roth IRA before following the step above. See how much a consistent contribution grows over time with our compound interest calculator.

Level 3 — Return to 401(k): If you’ve maxed your Roth IRA ($7,500 plus a $1,100 catch-up, or $8,600 total for age 50 and older) and still have room, put the rest into your 401(k) up to the $24,500 limit. You may also qualify for the Saver’s Credit (the Retirement Savings Contributions Credit) on the contributions this post describes. For 2026, the income limits published in IR-2025-111 are $80,500 if you are married filing jointly, $60,375 if you file as head of household, and $40,250 if you file as single or married filing separately. If your income is within those limits, check whether you can claim the credit for your retirement contributions.

Traditional 401(k) vs. Roth 401(k): Which Limit Applies?

The $24,500 limit is a combined limit across both traditional and Roth 401(k) contributions. If your plan offers a designated Roth option, you can generally split your regular contributions between traditional (pre-tax) and Roth 401(k) in any proportion your plan permits, as long as the combined total does not exceed $24,500 for 2026. If your plan does not offer a Roth feature, no split is available. One exception applies to catch-up contributions in 2026: if your 2025 wages from the sponsoring employer exceeded $150,000, your 2026 catch-up contributions must be designated as Roth contributions — you cannot choose to make those catch-ups pre-tax.

Traditional 401(k): contributions are pre-tax, meaning you reduce your taxable income now and pay taxes on withdrawals in retirement. Best if you expect to be in a lower tax bracket in retirement than you are today.

Roth 401(k): contributions are after-tax. You don’t get the upfront tax break, but qualified withdrawals in retirement are completely tax-free — including all the growth. What ’qualified’ means for a Roth 401(k): a distribution is qualified only if it occurs at least five years after the year of your first designated Roth contribution, and it is made on or after age 59-1/2, on account of disability, or after your death. A distribution that does not meet those conditions is nonqualified, and the portion attributable to earnings is taxed, on a pro-rata basis between earnings and contributions. Best if you expect to be in the same or higher tax bracket in retirement, or if you’re early in your career and your income will grow significantly.

Many people split contributions — putting some into traditional to reduce today’s taxes and some into Roth to build tax-free income for later. There’s no single right answer; it depends on your tax situation and timeline.

What Happens If You Over-Contribute?

If you exceed the $24,500 limit, the excess is subject to income tax in the year it was contributed — and it gets taxed again when you withdraw it in retirement if you don’t fix it in time. This is called a “double taxation” problem and it’s a headache you want to avoid.

If you over-contribute, do not wait for your plan to tell you. It is your responsibility to monitor your total contributions across all your plans and to notify your plan administrator before April 15 of the following year that you want the excess amount, adjusted for earnings, distributed to you. This is especially important if you changed jobs during the year and contributed to plans with unrelated employers, because no single plan can see your combined total. To fix it: you must withdraw the excess contributions (plus any earnings on them) by April 15 of the following year. What happens when you correct an excess in time: any earnings included in the corrective distribution are taxed in the year the distribution is made, not the year you contributed them. The corrective distribution itself is not subject to the additional 10% tax on early distributions. Do not assume an extension helps — the April 15 deadline is not postponed by a filing extension and is not tied to the due date of your tax return. Leaving an uncorrected excess in the plan carries a further risk: it can put the plan’s qualified status at risk. Whether or not you are with a single employer, do not rely on anyone else to catch an over-contribution for you. Keep track of your own total deferrals during the year, and if you have over-contributed, notify your plan administrator before April 15 of the following year so the excess, adjusted for earnings, can be distributed.

The most common scenario where this happens: changing jobs, contributing to both employers’ plans, and not tracking the combined total. If you switch employers in 2026, keep a running count of what you’ve contributed across all plans for the year.

How to Increase Your 401(k) Contribution Without Feeling It

The easiest way to contribute more without a painful lifestyle change: increase your contribution rate every time you get a raise. If your pay goes up 3%, bump your contribution by 1–2%. You never feel the increase because your take-home is still rising — just slightly less than your gross raise.

Some plans may offer a feature that increases your contribution rate automatically over time. Whether that feature is available, how it works, and whether you must opt in or may opt out are all set by your own plan’s terms — check your plan documents or ask your plan administrator before relying on it. If your plan has this, opt in. It’s the laziest and most effective way to close the gap between where you are and the maximum limit over several years.

Even going from 3% to 5% to 8% over a few years of raises makes a significant difference in your retirement balance — without requiring you to cut back your current spending in a way that feels punishing.
