Workers saving for retirement through a 401(k) plan can set aside $1,000 more per year starting in 2026, after the IRS raised the elective deferral limit to $24,500, up from $23,500 in 2025. For savers age 50 and older, the catch-up contribution allowance rises to $8,000, bringing their combined ceiling to $32,500. The increases, announced in IRS Newsroom release IR-2025-111, take effect for taxable years beginning after December 31, 2025, and they land as plan sponsors face a tight window to update payroll systems before the new year.
Why the $24,500 deferral ceiling changes the math for older savers
The $1,000 bump in the base deferral limit is a cost-of-living adjustment tied to annual inflation indexing. By itself, it adds modest room for rank-and-file participants. The bigger shift hits workers over 50, who gain $500 in additional catch-up space, moving from $7,500 in 2025 to an $8,000 catch-up for 2026. That means an eligible 52-year-old can defer up to $32,500 across regular and catch-up contributions, a combined increase of $1,500 over 2025 levels.
For higher earners in their peak earning years, the larger ceiling may help close retirement savings gaps that built up earlier in their careers. Someone making $160,000 who contributes the full $24,500 will be deferring just over 15% of pay, and the additional $8,000 catch-up can push that rate above 20% if they are 50 or older. Those percentages matter because many financial planners view 15%–20% of income, including employer matches, as a rough benchmark for maintaining one’s standard of living in retirement.
The practical question is how many participants will actually use the new headroom. Plans that rely on voluntary elections tend to see slow adoption of higher limits, because workers must actively log in and change their deferral percentage. Plans with automatic enrollment or automatic escalation features are better positioned to push average deferral rates higher, since the system raises contributions on a preset schedule. Whether that gap widens in 2026 should become visible when plan sponsors file their annual Form 5500 reports, which disclose aggregate contribution data. Until those filings arrive, the real-world impact of the limit increase will be hard to measure.
IRS tables and regulatory text behind the 2026 numbers
The agency published the new figures through two channels. The newsroom release covers the headline numbers, while the official COLA tables for retirement plans lay out year-over-year comparisons from 2023 through 2026 and cross-reference Notice 2025-67 for the technical methodology. Both confirm that the $8,000 catch-up limit applies equally to 401(k), 403(b), and profit-sharing plans, and that the same indexed formulas drive the elective deferral ceiling.
For plan sponsors and benefits administrators, the tables do more than list dollar amounts. They also show how the 401(k) elective deferral cap interacts with overall contribution limits under Section 415, which govern the combined total of employee and employer contributions. That interplay can be important for highly compensated employees who bump up against multiple ceilings at once, especially in profit-sharing designs that allow large employer nonelective contributions.
Separately, SECURE 2.0 amendments created a higher catch-up tier for workers between ages 60 and 63. The regulatory framework for that provision sits in 26 CFR 1.414(v)-1, which defines how catch-up eligibility and administration work under Internal Revenue Code Section 414(v). The enhanced limit for that narrow age band is distinct from the standard $8,000 catch-up and could allow even larger deferrals for workers in their early sixties, though the IRS announcement focused on the broadly applicable figures rather than the age-60-to-63 tier.
IRA limits and coordination with workplace plans
The IRA contribution limit also rises in 2026, reaching $7,500 for individuals under 50, with an additional catch-up amount preserved for older savers. While the IRA ceiling is far lower than the 401(k) elective deferral limit, the two can be used together. A worker can maximize salary deferrals into an employer plan and still contribute to a traditional or Roth IRA, subject to income-based eligibility rules that govern deductibility and Roth access.
The IRS notes in its contribution limits guidance that elective deferrals, catch-up contributions, and employer matching or nonelective contributions all count toward different statutory caps. Participants who split savings between a 401(k) and a 403(b) must also remember that the elective deferral limit is a combined figure across all such plans, not a per-plan maximum. By contrast, IRA contributions are tracked separately from workplace plan deferrals, which gives diligent savers an additional tax-advantaged bucket.
For individuals deciding where to focus first, workplace plans often take priority because of employer matching contributions and higher ceilings. Once a participant is on track to hit the $24,500 limit-or $32,500 with catch-up-additional dollars can flow into an IRA to diversify tax treatment or investment options. Coordinating these moves before the calendar year closes is critical, since 401(k) deferrals must be made through payroll, while IRA contributions can typically be made up to the tax filing deadline.
Next steps for employees and plan sponsors
With the 2026 limits now defined, employees have time to model how higher deferrals will affect take-home pay and long-term balances. Increasing contributions early in the year spreads the impact over more pay periods, making the change easier to absorb. Plan sponsors, meanwhile, need to verify that payroll systems, plan documents, and participant communications reflect the $24,500 elective deferral cap and the $8,000 catch-up. Clear notices explaining the new thresholds can help more workers take advantage of the expanded room before the year is over.
