401(k) Contribution Limits for 2026

The basic 401(k) contribution limit for 2026 is $24,500.

That is the number most people need first, but it is not the whole story. There is a separate catch-up limit for people age 50 and older, a higher catch-up for ages 60 through 63, and a much larger overall limit that can include employer contributions and—if the plan allows them—after-tax employee contributions.

There is also an important 2026 change for some higher-paid workers making catch-up contributions.

Here is the clean version before we get into the details.

These figures come from the IRS's 2026 retirement-plan limit announcement ↗ and its current 401(k) contribution-limit guidance ↗.

Quick answer:** If you are under 50, the most you can generally defer from your pay into traditional and Roth 401(k) accounts combined is $24,500 in 2026. If you are 50 or older, most plans can permit another $8,000. If you turn 60, 61, 62 or 63 during 2026, the special catch-up limit is $11,250 instead.

The 2026 employee 401(k) limit is $24,500

For 2026, an employee can generally make up to $24,500 in elective deferrals to a traditional 401(k), Roth 401(k), or a combination of the two.

This is up from $23,500 in 2025.

The word “employee” is important. The $24,500 limit applies to the money you elect to defer from your own compensation. Employer matching contributions do not reduce this limit.

If you put $20,000 into your 401(k) and your employer contributes another $8,000, you have not exceeded the $24,500 employee limit. Your own deferral is still $20,000.

Employer money is tracked under a different overall limit, which we cover below.

Traditional and Roth 401(k) contributions share the same limit

A common mistake is to assume you get a separate $24,500 limit for a traditional 401(k) and another $24,500 for a Roth 401(k).

You do not.

If your plan lets you make both types of contributions, the combined elective deferrals generally cannot exceed $24,500 in 2026 if you are under 50.

For example:

• $24,500 traditional + $0 Roth = allowed
• $12,250 traditional + $12,250 Roth = allowed
• $10,000 traditional + $14,500 Roth = allowed
• $24,500 traditional + $24,500 Roth = not allowed

The tax treatment is different, but the employee deferral ceiling is shared.

The age-50 catch-up limit is $8,000 in 2026

If you are age 50 or older by the end of 2026, your plan may allow catch-up contributions.

The standard catch-up limit for most 401(k) participants is $8,000 in 2026.

That means a participant who is 50 or older and is not in the special age-60-to-63 band can potentially make:

$24,500 regular deferral + $8,000 catch-up = $32,500

The plan must permit catch-up contributions. The IRS provides the current details in its catch-up contribution guidance ↗.

Ages 60 through 63 get a larger $11,250 catch-up

SECURE 2.0 created a larger catch-up limit for participants who reach ages 60, 61, 62 or 63 during the calendar year.

For 2026, that special catch-up is $11,250.

So an eligible participant in that age band can potentially defer:

$24,500 + $11,250 = $35,750

Once the participant is outside that age range, the standard age-50 catch-up amount applies again, assuming the participant remains eligible for catch-up contributions.

This is worth checking carefully around birthdays because the rule is based on the age you attain during the calendar year.

A major 2026 change: Roth catch-up for some higher-paid workers

Beginning in 2026, some higher-paid participants who make catch-up contributions must make those catch-up contributions on a Roth basis.

The IRS states that participants in plans with Roth features offering catch-up contributions must use Roth treatment for catch-up contributions if their prior-year wages from the plan sponsor exceeded $150,000 for 2026.

In practical terms, this can affect people who are 50 or older, earn above the threshold from the employer sponsoring the plan, and want to make catch-up contributions.

Why this matters: Roth 401(k) contributions are made after tax. You do not get the same current-year reduction in taxable income that you generally get from pre-tax traditional 401(k) deferrals.

The regular $24,500 deferral can still involve traditional and/or Roth contributions according to plan terms and your election. The special rule concerns the catch-up portion for covered higher-paid participants.

Because payroll implementation and plan design matter, check your employer's 2026 enrollment materials if this rule could apply to you.

Employer match does not count against the $24,500 limit

This is one of the most useful rules to understand.

Suppose you earn $100,000 and contribute the full $24,500. Your employer also contributes $5,000.

Your total additions are $29,500, but your elective deferral is still only $24,500. The employer's $5,000 did not “use up” part of your employee limit.

The employer contribution does count toward the separate $72,000 overall annual-additions limit for 2026.

If you are trying to understand how valuable your employer contribution is, see our guide to the average 401(k) match in 2026.

Put the limit in employer context:** The law tells you how much *you* may contribute. Search your employer to see how much employer money the plan reported historically. The filing amount is not the current match formula, but it can add useful context.

The overall 2026 401(k) limit is $72,000

The second big number is the annual-additions limit under Internal Revenue Code Section 415(c).

For 2026, it is generally the lesser of:

• $72,000, or
• 100% of the participant's compensation, subject to the applicable rules

The $72,000 limit can include:

• Employee elective deferrals
• Employer matching contributions
• Employer nonelective contributions
• Certain after-tax employee contributions
• Allocations of forfeitures

Catch-up contributions are generally allowed on top of the annual-additions limit.

This distinction is why someone can have more than $24,500 added to a 401(k) in one year without violating the rules.

Example: employee contribution plus employer match

You contribute: $24,500 Employer contributes: $10,000 Total: $34,500

That is below the $72,000 annual-additions limit.

Example: employer contribution plus after-tax contribution

You contribute $24,500 in regular elective deferrals. Your employer adds $12,000. If the plan permits voluntary after-tax contributions, you may have additional room under the $72,000 limit, subject to your compensation and the plan's rules.

This is the territory often associated with “mega backdoor Roth” strategies, but not every plan permits the necessary after-tax contributions or in-plan conversion/rollover features. Do not assume your plan does just because federal law allows a higher overall ceiling.

What is the absolute maximum that can go into a 401(k) in 2026?

For someone eligible for catch-up contributions, the maximum can exceed $72,000 because catch-up contributions sit on top of the annual-additions limit.

For 2026:

• Under age 50: up to $72,000 under the overall limit, assuming sufficient compensation and plan features
• Age 50+ outside ages 60–63: potentially $80,000 ($72,000 + $8,000 catch-up)
• Ages 60–63: potentially $83,250 ($72,000 + $11,250 special catch-up)

Those are theoretical ceilings. Reaching them usually requires substantial employer contributions and/or a plan that permits voluntary after-tax contributions. Most employees will be focused on the $24,500 salary-deferral limit instead.

The 2026 compensation limit is $360,000

The IRS caps the amount of annual compensation that a qualified retirement plan can take into account for certain plan purposes.

For 2026, that compensation limit is $360,000.

This can matter for matching formulas.

Suppose a plan matches a percentage of eligible compensation. A highly paid employee may assume the match simply continues against every dollar of salary, but qualified-plan compensation limits can cap the compensation used in the calculation.

The details depend on the plan's formula and definition of compensation, so a benefits summary is not always enough. Check the plan document.

What if you have two 401(k)s in the same year?

Job changes create one of the easiest ways to accidentally over-contribute.

Suppose you leave Employer A in June after contributing $15,000 to its 401(k). You start Employer B in July. You do not normally get a fresh $24,500 employee limit just because you changed jobs.

Your elective deferrals generally have to be aggregated across the 401(k) and 403(b) plans subject to the same Section 402(g) limit.

In this example, you would generally have $9,500 of regular 2026 elective-deferral room remaining:

$24,500 − $15,000 = $9,500

Your new employer's payroll system may not know what you contributed at the old job. You need to track it.

If you are changing jobs, our guide on what happens to your 401(k) when you leave covers the account decisions separately from the annual contribution limit.

What about a 401(k) and a 403(b)?

The $24,500 elective-deferral limit generally applies across your 401(k) and 403(b) elective deferrals combined.

So contributing $20,000 to a 401(k) and $20,000 to a 403(b) in 2026 would ordinarily exceed the shared elective-deferral limit unless another special rule applies.

A governmental 457(b) is different: it generally has its own separate elective-deferral limit. That can create significantly more tax-advantaged saving room for an employee who has access to both a 403(b) or 401(k) and a governmental 457(b).

For a broader comparison, see 401(k) vs. 403(b).

How much should you contribute per paycheck to max out your 401(k)?

Divide the amount you want to contribute by your remaining pay periods—but check the employer match before you front-load contributions.

For a full calendar year, the simple math looks like this:

Real payroll can differ because of rounding, bonuses, compensation changes and the timing of elections.

More importantly, some employers match contributions paycheck by paycheck. If you hit the annual limit in October and stop contributing, you might miss November and December matching dollars unless the plan provides a year-end true-up.

Before maxing out early, verify:

• Is the match calculated each payroll?
• Is there a true-up?
• Does the true-up require you to be employed on a particular date?
• Are bonuses included in eligible compensation?

The mathematically fastest path to $24,500 is not always the path that produces the largest employer contribution.

What happens if you contribute too much?

If your elective deferrals exceed the annual limit, the excess generally needs to be corrected.

This most often happens when someone contributes to more than one employer plan during the year. Because each payroll provider sees only its own plan, neither system may stop you at the correct combined amount.

Contact the plan administrator promptly if you discover an excess. Tax reporting and corrective-distribution rules can become more complicated if the problem is not fixed on time.

The IRS provides plan-level guidance on excess elective deferrals; for a personal tax situation, consider getting qualified tax advice rather than relying on a generic online example.

Should you max out your 401(k)?

The annual limit is a ceiling, not a recommendation.

For some households, contributing $24,500—or more with catch-up contributions—is realistic and tax-efficient. For others, it would mean neglecting emergency savings, carrying expensive debt or missing other benefits.

A more useful sequence is often:

1. Understand the employer match and contribute enough to receive the full amount if your budget permits.
2. Maintain a workable emergency reserve.
3. Consider expensive debt and other near-term obligations.
4. Compare your 401(k)'s fees and investment choices with alternatives available to you.
5. Increase the contribution rate as cash flow improves.

There is no prize for hitting $24,500 if doing so leaves you unable to pay ordinary bills without borrowing the money back.

What your employer plan can change—and what it cannot

Federal law sets the maximum limits, but the plan can be more restrictive in some ways.

Your employer plan can determine or affect:

• Whether Roth 401(k) contributions are offered
• Whether catch-up contributions are offered
• Match and nonelective formulas
• Eligibility and entry dates
• After-tax contribution availability
• In-plan Roth conversions
• True-up provisions
• Investment choices
• Loan and distribution features

That is why two employees with the same salary and age can have very different retirement-plan opportunities.

The IRS limit is the same across qualifying 401(k)s; the plan quality is not. Read how to tell if a 401(k) plan is good, then use the database to compare your employer with peers.

Frequently asked questions

What is the 401(k) contribution limit for 2026?

The regular employee elective-deferral limit is $24,500 for 2026.

How much can someone age 50 or older contribute in 2026?

Most participants age 50 or older can contribute up to $24,500 plus an $8,000 catch-up, for $32,500, if the plan permits catch-up contributions. A special $11,250 catch-up applies for participants who turn 60, 61, 62 or 63 during 2026, potentially bringing employee deferrals to $35,750.

What is the total 401(k) contribution limit including employer match in 2026?

The overall annual-additions limit is generally $72,000 in 2026, or 100% of compensation if lower, before catch-up contributions. It can include employee deferrals, employer contributions and certain other additions.

Does an employer match count toward the $24,500 limit?

No. The $24,500 limit is the employee elective-deferral limit. Employer contributions count toward the separate overall annual-additions limit.

Can I contribute $24,500 to a traditional 401(k) and another $24,500 to a Roth 401(k)?

No. Traditional and Roth 401(k) elective deferrals generally share the same $24,500 employee limit.

If I change jobs, do I get a new $24,500 limit?

No. Your employee elective deferrals generally need to be aggregated across the relevant plans for the calendar year. Track contributions made at the old employer before setting the contribution rate at the new employer.

Bottom line

For most employees, the number to remember for 2026 is $24,500.

Then add the layers that apply to you:

• $8,000 catch-up if you are 50+ in most cases
• $11,250 catch-up instead if you turn 60–63 in 2026
• $72,000 overall annual-additions limit before catch-up contributions
• $360,000 annual compensation limit for qualified-plan purposes

The federal limits tell you how much room exists. Your employer's plan determines how useful that room is.

Once you know your limit, look up your employer's plan to put contributions, costs and plan history in context.
