401(k) Changes for 2026: Higher Limits, Roth Catch-Up Rules, and What to Do

For 2026, most 401(k) participants can defer $24,500 before age-based catch-ups. Eligible participants age 50 or older can reach $32,500, or $35,750 at ages 60–63. Affected higher earners must make the catch-up portion as Roth contributions. Check the year-to-date total and remaining paychecks now to coordinate the final 2026 elections.

Employer contributions and employee deferrals have different limits. Track both, then divide your remaining employee contribution room across the paychecks left in the year. Leave enough room in the election for any employer matching conditions.

Compare the 2025 and 2026 limits

The IRS published the 2026 contribution announcement as IR-2025-111. Its figures and the IRS cost-of-living table distinguish regular deferrals, catch-ups, and the overall defined-contribution limit. IRS announcement, IRS limit table.

Category	2025	2026
Regular employee 401(k) deferral	$23,500	$24,500
General age-50 catch-up	$7,500	$8,000
Total with general catch-up	$31,000	$32,500
Higher catch-up for ages 60–63	$11,250	$11,250
Total with higher catch-up	$34,750	$35,750
Overall defined-contribution dollar limit, excluding catch-ups	$70,000	$72,000
Combined traditional-and-Roth IRA contribution	$7,000	$7,500
IRA age-50 catch-up	$1,000	$1,100

The higher age-60–63 catch-up replaces the general catch-up; it is not added to it. For 2026, age 64 returns to the general age-50 category. Eligibility is based on the age attained during the calendar year, with catch-ups available only under a plan that permits them. IRS catch-up guidance.

What counts toward the $72,000 overall plan limit

Annual additions generally include regular employee deferrals, employer contributions, and employee after-tax contributions. The limit also cannot exceed the applicable compensation limit, and eligible catch-ups sit outside annual additions. A plan may restrict contributions further. IRS 401(k) contribution rules.

For example, $24,500 in regular deferrals plus $10,000 from the employer equals $34,500, leaving $37,500 below the $72,000 dollar ceiling. Using that remaining room requires another permitted contribution type, eligible compensation, and compliance with plan limits and testing. Ask the administrator whether employee after-tax contributions are available and what limit applies.

Calculate the employer contribution from the plan’s match formula. Review its compensation definition, payroll timing, and vesting schedule before changing elections. The overall federal ceiling and the employer’s promised contribution are separate numbers.

Determine whether the Roth catch-up rule applies

Beginning in 2026, the Roth catch-up requirement applies to affected participants whose prior-year wages from the plan sponsor exceeded $150,000. It concerns the catch-up portion, not all regular deferrals. The threshold is indexed; $150,000 is not a permanent statutory amount. IRS catch-up guidance, Fidelity plan-sponsor explanation.

Use the relevant employer wage measure, generally Social Security FICA wages, rather than household income or investment gains. Ask payroll to confirm the wage figure used. Job changes, multiple employers, and special plan circumstances can require additional analysis.

An employee turning 52 in 2026 with $160,000 of relevant 2025 wages from the same employer meets the wage trigger. If eligible for the full general catch-up, the $8,000 catch-up is Roth. The $24,500 regular portion can follow the plan’s available pretax or Roth choices.

At exactly $150,000 of relevant prior-year wages, the federal trigger described here is not met: the test is more than the threshold. Do not substitute current-year salary or a rounded estimate when payroll can supply the actual amount.

Separate 2026 implementation from the regulations’ 2027 date

The IRS’s final-regulations announcement says the Roth catch-up regulations generally apply to taxable years beginning after December 31, 2026, with later applicability for certain plans. It also expressly says the regulations do not extend the administrative transition period that generally ended December 31, 2025. Plans can use a reasonable, good-faith interpretation before the regulations’ general applicability date. IRS final-regulations announcement.

Ask the administrator how the plan implements 2026 catch-ups, including the election, payroll coding, and correction process. Check a pay statement after the election takes effect so the contribution’s tax treatment matches the plan’s instructions.

Convert the annual amount into a payroll plan

For 26 equal paychecks, the regular $24,500 ceiling corresponds to approximately $942.31 per paycheck. The $32,500 age-50 total corresponds to $1,250, while $35,750 divided by 26 is $1,375. These are full-year illustrations; rounding and a payroll system’s final-check adjustment matter.

Late in the year, use remaining capacity instead. If a hypothetical employee under 50 has deferred $20,000 and has 5 paychecks left, the remaining $4,500 requires $900 per paycheck, assuming sufficient eligible pay and no other relevant deferrals.

If you changed jobs, track contributions across employers. The regular elective-deferral limit generally applies across participating 401(k) and 403(b) plans; a new employer does not provide a fresh annual allowance. Governmental 457(b) arrangements have different aggregation treatment. IRS multiple-plan guidance.

Also ask whether matching occurs each paycheck and whether the plan has an annual true-up. That determines whether reaching the ceiling early could affect the match. Keep the question specific to the plan rather than assuming every employer corrects missed matching automatically.

Check automatic enrollment and escalation notices

The SECURE 2.0 automatic-enrollment requirement generally began with the 2025 plan year for covered newly established 401(k) and 403(b) plans. The IRS’s January 2025 proposed-regulations announcement describes an initial rate of at least 3%, with annual increases of 1 percentage point until reaching at least 10%, and exceptions for specified new or small businesses, church plans, and governmental plans. IRS automatic-enrollment announcement.

Read the enrollment notice for the actual default rate, escalation schedule, opt-out instructions, and investment choice. Compare the default deduction with the match formula and your own contribution target, then make an affirmative election if another rate fits better.

Long-term-care distributions have limits and documentation requirements

IRS Notice 2026-33 explains an optional feature for eligible employer defined-contribution plans, effective for distributions after December 29, 2025. For 2026, the qualified amount cannot exceed the least of certified long-term-care premiums for the employee or spouse, 10% of the vested benefit, or $2,600. A qualifying premium statement must be filed with the plan. IRS Notice 2026-33.

For example, with hypothetical eligible premiums of $3,000 and a $20,000 vested benefit, the percentage cap is $2,000, below $2,600. That would cap the qualified amount at $2,000 if all other conditions are satisfied.

A qualified distribution receives an exception from the 10% additional early-distribution tax; ordinary income tax can still apply. Confirm that the employer plan offers the feature and obtain the required premium statement before requesting it. Notice 2026-33 excludes reclassifying an ordinary withdrawal afterward when the plan has not adopted the feature.

Confirm the year-end result

Compare your final pay statements with the plan’s contribution record, separating pretax, designated Roth, employer, and any other contribution types. Resolve discrepancies with payroll promptly. Keep the relevant wage record and election confirmations so you can understand why catch-ups were classified as Roth.

Use the contribution ceiling as a constraint within a broader budget. A sustainable increase, correctly processed and coordinated with the match, is more useful than an election that creates a cash shortage or an avoidable excess contribution.
