401(k) Contribution Limits for 2026

Planning your 2026 retirement contributions can be confusing because several limits apply at the same time. You may see a $24,500 employee limit, a $72,000 total limit, an $8,000 catch-up amount, and a separate $11,250 catch-up for certain ages. These figures do not describe the same contribution. For 2026, most employees can contribute up to $24,500 from their pay to a 401(k). Participants age 50 or older may qualify for an additional $8,000, while participants who turn 60, 61, 62, or 63 during the year may qualify for the higher $11,250 catch-up contribution. Employer contributions can increase the total amount added to the account, but they do not increase the regular employee payroll-deferral limit.

2026 401(k) Limits at a Glance

The IRS applies separate limits to employee salary deferrals, age-based catch-up contributions, and total contributions from all eligible sources. Identifying the correct category is important because an employee generally cannot contribute the full $72,000 directly from regular salary deferrals. Most of that higher limit must be reached through a combination of employee contributions, employer funding, and voluntary after-tax contributions when the plan permits them.

The catch-up amounts can be added above the regular annual-additions limit when the participant is eligible and the employer’s plan permits catch-up contributions. The participant must also have enough eligible compensation to support the contribution. A plan document, payroll system, or nondiscrimination requirement may impose a lower practical limit than the federal maximum.

How the Employee and Total Contribution Limits Work

The most important distinction is between the amount an employee can elect to contribute from pay and the total amount that can be added to the account from employee and employer sources. The $24,500 employee limit applies across the participant’s applicable elective deferrals, while the $72,000 annual-additions limit measures a broader group of contributions.

The $24,500 Employee Elective-Deferral Limit

An employee elective deferral is money that a participant chooses to direct from compensation into a 401(k) through payroll. The 2026 elective-deferral limit is $24,500 or 100% of the employee’s compensation, whichever is lower. This federal limit covers both traditional pretax and designated Roth 401(k) contributions.

Traditional and Roth contributions do not receive separate $24,500 limits. The participant can divide the annual amount between the two contribution types, but the combined total generally cannot exceed $24,500 before age-based catch-ups.

Traditional contributions are generally made before federal income tax is applied, while designated Roth contributions are included in current taxable income. The choice between them affects the timing of taxation, but it does not change the regular employee contribution ceiling.

Contributions That Do Not Reduce the $24,500 Limit

Employer contributions do not normally reduce the amount an employee can contribute through regular salary deferrals. An employee can therefore contribute the full $24,500 and still receive an employer match or other employer funding, subject to the broader annual-additions limit and the written terms of the plan.

Contributions that generally do not count against the regular employee elective-deferral limit include:

●     Employer matching contributions

●     Employer nonelective contributions

●     Employer profit-sharing contributions

●     Eligible age-based catch-up contributions

●     Voluntary non-Roth after-tax contributions

Not every plan offers all these contribution types. Employees should check the plan’s summary plan description or ask the plan administrator which options are available.

The $72,000 Annual-Additions Limit

The annual-additions limit measures the total amount credited to a participant’s account from several sources. For 2026, the general limit is the lesser of $72,000 or 100% of the participant’s eligible compensation. Catch-up contributions are generally excluded from this calculation and may be added above the regular cap.

Annual additions generally include:

●     Traditional employee deferrals

●     Roth employee deferrals

●     Voluntary non-Roth after-tax employee contributions

●     Employer matching contributions

●     Employer nonelective contributions

●     Employer profit-sharing contributions

●     Allocated forfeitures, where applicable

Consider an employee under age 50 who contributes $24,500 and receives $12,000 from the employer. The account receives $36,500 in annual additions. The employee has reached the personal elective-deferral maximum but remains below the $72,000 total limit.

Some plans allow voluntary after-tax contributions that can use part of the remaining annual-additions space. In this example, the theoretical remaining space would be $35,500. The employee could use that space only if the plan permits after-tax contributions, compensation is sufficient, and no other plan restrictions apply.

How Catch-Ups Affect the Total Maximum

Eligible catch-up contributions can increase the total amount credited to the account beyond $72,000. A participant under age 50 may have up to $72,000 in total annual additions. A participant eligible for the standard $8,000 catch-up may reach $80,000, while a participant eligible for the $11,250 ages 60–63 catch-up may reach $83,250.

These are maximum legal amounts, not amounts that every employee can contribute directly from salary. Reaching them usually requires a plan that permits several contribution sources and an employer willing to make substantial matching, nonelective, or profit-sharing contributions.

The $360,000 Compensation Limit

For 2026, a qualified retirement plan generally cannot use more than $360,000 of compensation when applying certain contribution and benefit formulas. This limit can affect an employer match, profit-sharing allocation, or other plan-based calculation. The compensation limit does not mean an employee must earn $360,000 to contribute $24,500. A participant earning less may still reach the employee limit if compensation is sufficient and the plan allows the necessary payroll-deferral percentage.

2026 Catch-Up Limits by Age

Catch-up contributions allow older participants to contribute above the regular $24,500 employee limit. Eligibility is generally based on the age the participant reaches by the end of the calendar year. The plan must permit catch-up contributions, and the employee must have enough compensation to make them.

Participants Under Age 50

Employees who remain under age 50 throughout 2026 generally have a maximum elective-deferral limit of $24,500. They are not eligible for an age-based catch-up contribution. Employer contributions may still increase the total added to the account, but they do not change the employee’s regular salary-deferral limit.

Participants Ages 50–59

A participant who is age 50 or older by December 31, 2026, may qualify for the standard $8,000 catch-up contribution. This raises the maximum employee contribution to $32,500.

The calculation is:

$24,500 regular employee contribution

●     $8,000 catch-up contribution
= $32,500 maximum employee contribution

The participant does not have to prove that retirement savings are behind schedule. “Catch-up contribution” is simply the name given to the additional age-based amount.

Participants Ages 60–63

SECURE 2.0 established a higher catch-up limit for participants who turn 60, 61, 62, or 63 during the calendar year. For 2026, that higher amount is $11,250.

The calculation is:

$24,500 regular employee contribution

●     $11,250 higher catch-up contribution
= $35,750 maximum employee contribution

The $11,250 amount replaces the standard $8,000 catch-up. It is not added on top of it. An eligible 61-year-old therefore cannot contribute $24,500 plus $8,000 plus $11,250.

Participants Age 64 and Older

A participant who is age 64 or older by the end of 2026 returns to the standard $8,000 catch-up limit. The maximum employee contribution is therefore $32,500 rather than $35,750. The higher catch-up is limited to the four calendar-year ages specified in the law. It does not continue after age 63.

How Age Eligibility Is Determined

Eligibility is generally based on the age the participant attains during 2026, even if the birthday occurs late in the year. A participant who turns 60 on December 31, 2026, may fall within the higher catch-up category for that year, subject to the terms and administration of the employer’s plan. Employees approaching ages 50, 60, or 64 should review their payroll elections before the relevant year begins. Payroll systems do not always adjust an employee’s contribution election automatically.

The 2026 Roth Catch-Up Requirement

A major 2026 change affects certain higher-paid employees who make catch-up contributions. If a participant had more than $150,000 in applicable 2025 wages from the employer sponsoring the plan, eligible catch-up contributions for 2026 generally must be designated as Roth contributions. Roth catch-up contributions are included in current taxable income instead of receiving an immediate pretax benefit.

Who May Be Affected

The Roth catch-up requirement generally applies when:

1. The employee is eligible to make an age-based catch-up contribution.
2. The employee received more than $150,000 in applicable 2025 FICA wages from the employer sponsoring the plan.
3. The employee makes contributions that are classified as catch-up contributions.
4. The plan permits the required designated Roth treatment.

The threshold is employer-specific. It is not based on household income, adjusted gross income, investment earnings, a spouse’s wages, or total earnings from every unrelated employer.

Which Wages Are Used

For catch-up contributions made in 2026, the wage test generally looks back to applicable FICA wages paid by the sponsoring employer during 2025. A person could have total income above $150,000 but remain outside the rule if wages from that specific employer did not exceed the threshold. Another person could fall under the rule based on employer wages even though household deductions reduce taxable income.

Employees who changed jobs should ask the new plan administrator how the employer-specific wage test applies. The result may differ from the treatment of an employee who remained with one employer for both years.

Only the Catch-Up Portion Must Be Roth

The rule does not automatically require the employee’s full regular contribution to be Roth. An affected participant may still be able to divide the regular $24,500 employee deferral between traditional and Roth contributions.

The required Roth treatment generally applies to the contribution amount classified as an age-based catch-up. For example, a participant subject to the rule could contribute $24,500 on a pretax basis and then direct an eligible $8,000 or $11,250 catch-up amount to the designated Roth account.

What If the Plan Does Not Offer Roth Contributions?

A plan is not generally required to offer a designated Roth account. However, an employee subject to the Roth catch-up mandate needs an available Roth feature to make the required catch-up contribution. If the plan does not include a qualified Roth contribution program, the affected employee may be unable to make a catch-up contribution under that plan.

Employees who expect to exceed the $24,500 regular limit should confirm the following with payroll or the plan administrator:

●     The prior-year wage amount being used

●     Whether catch-up contributions are permitted

●     Whether the plan has a designated Roth account

●     How payroll will classify the catch-up amount

●     Whether a new contribution election is required

●     How the rule applies after a job change

How Employer Contributions Affect the Limit

Employer contributions can increase retirement savings without reducing the employee’s regular $24,500 deferral limit. They do, however, count toward the broader $72,000 annual-additions cap. The actual amount depends on the employer’s written plan formula.

Employer Matching Contributions

An employer match is commonly based on how much the employee contributes and a stated percentage of eligible compensation. For example, an employer might contribute a set amount for each dollar the employee defers, up to a stated portion of pay.

Suppose an employee under age 50 contributes $24,500 and receives a $9,000 match:

The employee has reached the regular personal limit, but the account remains below the $72,000 annual-additions maximum. Matching formulas, eligibility periods, and vesting rules differ by plan. A competitive employer match can also supportemployee retention through retirement benefits by giving workers another financial reason to participate in the plan and remain with the organization. Participants should use the plan’s actual formula rather than assuming that every employer contributes the same percentage.

Nonelective and Profit-Sharing Contributions

An employer may make a nonelective contribution even when an employee does not contribute from salary. A business may also make a profit-sharing contribution based on the written allocation formula in the plan. These contributions generally count toward the $72,000 annual-additions limit. They may be particularly important for business owners reviewing how the plan serves owners, highly compensated employees, and the wider workforce. Business owners comparing retirement-plan structures should also consider howdefined benefit and defined contribution plans differ in contribution flexibility, employer obligations, employee benefits, and retirement-income outcomes.

Voluntary After-Tax Contributions

Some 401(k) plans permit non-Roth after-tax employee contributions after the employee has reached the regular elective-deferral limit. These amounts are different from Roth contributions. The contribution itself has already been taxed, but its future earnings do not automatically receive the same qualified tax-free treatment as earnings in a designated Roth account.

Voluntary after-tax contributions count toward the $72,000 annual-additions limit. Their availability depends entirely on the plan document and administration. Employees should confirm whether the option exists before calculating contributions based on the unused annual-additions space.

Avoid Missing Part of the Employer Match

Some employers calculate matches during each payroll period. A participant who reaches the annual employee limit several months before year-end may stop receiving matching contributions during later payroll periods unless the plan provides a year-end true-up.

Before front-loading contributions, review:

●     Whether the match is calculated each payroll period

●     Whether a year-end true-up is provided

●     Whether bonuses receive matching contributions

●     Whether the employee must be employed on a specific date

●     Whether employer contributions are subject to vesting

These details are controlled by the plan, not by the federal contribution ceiling.

What If You Have More Than One 401(k)?

The employee elective-deferral limit generally follows the participant across applicable plans. Changing jobs or working for two unrelated employers does not normally create a new $24,500 employee limit for each 401(k). The employee must track total deferrals because one employer may not know how much was contributed through another employer.

Changing Jobs During 2026

Suppose an employee contributes $14,500 to Employer A’s 401(k) and then begins working for Employer B. The employee generally has $10,000 of the regular 2026 elective-deferral limit remaining:

$24,500 annual limit
− $14,500 contributed through Employer A
= $10,000 remaining

If the employee is eligible for a catch-up contribution, the applicable $8,000 or $11,250 catch-up amount may provide additional room.

The second employer’s payroll system may allow the employee to elect the full annual maximum because it does not have access to the first employer’s records. The participant remains responsible for monitoring the combined total.

Traditional and Roth Contributions Across Employers

Traditional and Roth deferrals remain subject to the shared employee limit even when made through different employers. An employee cannot contribute $24,500 to a traditional account at one company and another $24,500 to a Roth account at another company.

Employees with more than one plan should track:

●     Traditional deferrals

●     Roth deferrals

●     Catch-up contributions

●     Final pay statements from previous employers

●     Forms W-2

●     Any payroll corrections

Other Workplace Plans

Employee deferrals to a 401(k) and a 403(b) generally need to be coordinated under the shared elective-deferral rules. A governmental 457(b) plan generally has a separate employee limit, although its plan-specific rules still apply. Business ownership, controlled companies, self-employment, and participation in several employer plans can create additional aggregation rules. Participants in those situations should request a plan-specific calculation rather than assuming each account receives a separate maximum.

What Happens If You Exceed the 2026 Limit?

An excess deferral occurs when total employee elective deferrals to applicable plans exceed the permitted annual amount. This often happens after a job change, when a person works for two employers, or when traditional and Roth contributions are tracked separately instead of being combined.

Common Causes of Excess Deferrals

An employee may exceed the limit because of:

●     Changing employers during the year

●     Contributing through two payroll systems

●     Failing to combine traditional and Roth deferrals

●     Using the wrong age-based catch-up amount

●     A payroll processing error

●     Failing to coordinate a 401(k) with another applicable plan

Reviewing year-to-date contributions after every job or payroll change can identify the problem before the final pay period.

Correcting an Excess Deferral

The employee should contact the plan administrator promptly and request a corrective distribution. The request should identify the excess amount, contribution type, plans involved, and any associated earnings. The IRS generally requires the excess deferral to be distributed by April 15 of the following year, or an earlier deadline established by the plan. The April 15 correction date is separate from an extension of the participant’s personal tax-return deadline.

Why Timely Correction Matters

When an excess is corrected on time, the excess amount and related earnings receive specific tax-reporting treatment. The plan may issue Form 1099-R for the corrective distribution. If the excess is not removed by the correction deadline, it may effectively be taxed once in the year contributed and again when later distributed. The IRS also warns that leaving certain excess deferrals uncorrected can create qualification problems for the plan.

Because reporting depends on the contribution type and correction timing, employees should coordinate with the plan administrator and a qualified tax professional.

How to Apply the 2026 Limit to Your Paycheck

Knowing the annual limit does not automatically set the correct payroll election. Employees must translate the annual goal into a dollar amount or percentage that fits the number of remaining pay periods, expected compensation, employer matching formula, and household cash flow.

Calculate a Contribution Per Paycheck

A basic calculation is:

Annual employee contribution goal ÷ number of pay periods = contribution per paycheck

To contribute $24,500 evenly throughout a full year:

These figures may require payroll rounding. They also assume the election begins with the first pay period and remains unchanged throughout the year.

An employee making a midyear change should divide the remaining contribution goal by the number of remaining paychecks rather than by the full-year number of pay periods.

Calculate a Percentage of Pay

Employees whose plan requires a percentage election can use:

Annual contribution goal ÷ expected eligible compensation × 100

For example:

$24,500 ÷ $100,000 expected eligible compensation = 24.5%

This percentage may need adjustment if the employee receives a raise, bonus, commission, unpaid leave, or another change in eligible compensation.

Review the Election During the Year

A contribution election should be reviewed after:

●     A salary increase

●     A bonus

●     A job change

●     Turning age 50

●     Entering the ages 60–63 catch-up window

●     Turning age 64

●     A period of unpaid leave

●     A change in the employer match

●     A payroll-system update

Employees should also check whether increasing contributions could cause them to reach the limit too early and lose matching contributions later in the year.

How Much Should You Contribute in 2026?

The IRS maximum is a legal ceiling, not a required savings target. Contributing $24,500 may be appropriate for one household and unaffordable or unnecessary for another. The decision should account for the employer match, current cash flow, emergency reserves, debt, tax position, retirement timeline, and existing savings. A suitable contribution rate should support the household’s widerretirement planning strategies, rather than forcing the participant to neglect emergency savings, debt payments, or other important financial goals.

Start With the Employer Match

A practical first step is identifying the contribution needed to receive the full available employer match. The employee should confirm the exact matching formula, eligibility requirements, payroll-period calculation, and vesting schedule. Failing to contribute enough may leave part of the available employer benefit unused. Contributing the full annual maximum is not required to capture the full match under many plan formulas.

Decide How to Use Traditional and Roth Contributions

Traditional contributions may reduce current federal taxable income, while Roth contributions are made with after-tax dollars. Qualified Roth distributions may be received free of federal income tax when applicable requirements are met. The appropriate mix depends on current tax rates, expected future tax rates, retirement income sources, and the plan’s available options. The decision should be coordinated with the participant’s wider tax and retirement plan rather than based solely on the annual contribution limit.

Review the Full Workplace Plan

A high contribution rate cannot correct every weakness in a retirement plan. Participants should also review:

●     Investment choices

●     Asset allocation

●     Plan fees

●     Employer contributions

●     Vesting

●     Beneficiary information

●     Old employer accounts

●     Retirement income needs

A participant may contribute the maximum and still have an investment mix, fee structure, or account arrangement that does not fit the wider financial plan.

How Mercer Wealth Management Can Help

Contribution limits are one part of workplace retirement planning. Employees and business owners also need to consider plan costs, investment options, employer funding, tax treatment, account consolidation, and how the plan supports long-term retirement income.

Mercer Wealth Management serves individuals and business owners from its Hamilton, New Jersey office. Its 401(k) and retirement services include employer-plan evaluations, fee benchmarking, investment reviews, plan design, employee education, retirement-account consolidation, and rollover guidance.

Support for Employees and Individuals

Mercer can help individuals review:

●     Current payroll elections

●     Traditional and Roth contribution choices

●     Employer matching formulas

●     Workplace investment options

●     Plan fees

●     Old 401(k) accounts

●     Rollover choices

●     Contribution levels within a wider retirement plan

The purpose of the review is not simply to reach the IRS maximum. It is to determine whether the contribution rate and account structure support the individual’s retirement timeline, cash-flow needs, tax position, and other financial goals.

Support for Employers and Business Owners

Business owners must consider both participant outcomes and plan-management responsibilities. Mercer’s retirement-plan services can support reviews of plan fees, investment lineups, plan design, owner-focused contribution strategies, employee education, and fiduciary processes.

A 2026 plan review may also help determine whether payroll procedures and participant communications properly address:

●     The new contribution limits

●     Ages 60–63 catch-up contributions

●     Roth catch-up treatment

●     Employer matching formulas

●     After-tax contribution options

●     Excess-deferral corrections

The Bottom Line

The regular employee 401(k) contribution limit 2026 is $24,500. Participants ages 50–59 and 64 or older may qualify for an additional $8,000 catch-up, while those ages 60–63 may qualify for an $11,250 higher catch-up. Employer and voluntary after-tax contributions may increase total annual additions up to $72,000 before eligible catch-ups, but the plan’s terms and the participant’s compensation still apply.

Traditional and Roth employee contributions share the same regular limit, and certain higher-paid employees must make eligible catch-up contributions on a Roth basis. Employees with multiple jobs must track their combined deferrals, while business owners should confirm that plan documents, payroll systems, and employee communications reflect the 2026 rules. Mercer Wealth Management can help employees and business owners review these limits in the context of a complete workplace retirement strategy.
