Americans age 50 and older will be able to stash an extra $8,000 in catch-up contributions to their 401(k) plans starting in 2026, up from $7,500 in 2025. The IRS confirmed the increase through Notice 2025-67, published in Internal Revenue Bulletin 2025-49, as part of its annual cost-of-living adjustments for retirement accounts. Combined with a new base 401(k) deferral limit of $24,500, the change gives older workers a total ceiling of $32,500 in elective deferrals next year. A separate, higher catch-up tier for participants ages 60 through 63 stays at $11,250 under rules created by the SECURE 2.0 Act.
Higher catch-up limits collide with a new Roth mandate
The $500 bump in the standard catch-up limit matters on its own, but a parallel regulatory shift makes 2026 a more complex year for plan sponsors and participants alike. Final regulations published in the Federal Register on September 15, 2025, spell out that certain higher-paid workers must now direct their catch-up dollars into Roth accounts rather than traditional pretax buckets. Under 26 CFR 1.414(v)-2, any participant whose prior-year wages from the sponsoring employer exceeded an indexed threshold, initially set at $145,000, must make catch-up contributions on an after-tax Roth basis.
That requirement creates a practical question for employers running automatic enrollment or automatic escalation features. Plans that funnel older participants into catch-up contributions by default will need systems capable of splitting deferrals between pretax and Roth channels based on each worker’s compensation history. The combination of a higher dollar limit and a mandatory Roth channel for earners above the wage threshold could produce a visible jump in Roth catch-up activity during the first two plan years after implementation, particularly among workers in their late 50s and early 60s who are trying to maximize tax-diversified savings before retirement.
IRS figures and SECURE 2.0 rules driving the 2026 limits
The numbers flow from two distinct sources of authority. The annual inflation adjustment raised the standard catch-up ceiling to $8,000 for 401(k), 403(b), most governmental 457, and Thrift Savings Plan accounts, according to the IRS bulletin. The same announcement set the base elective deferral limit at $24,500 and the IRA contribution limit at $7,500 for 2026, reflecting cost-of-living increases built into the tax code.
Those limits align with the agency’s separate news release on the 2026 salary deferral caps, which confirms that the standard 401(k) ceiling rises to $24,500 while the IRA maximum moves to $7,500. The IRS announcement also reiterates that the age-50 catch-up rules apply across multiple plan types, giving older savers more room to accelerate their retirement savings as they approach the end of their careers.
The enhanced catch-up tier for ages 60 through 63, which allows contributions of $11,250 instead of $8,000, traces back to the SECURE 2.0 Act of 2022. That law was enacted as Division T of H.R. 2617, the Consolidated Appropriations Act, 2023, and directed Treasury to create a higher “special” catch-up band for workers in their early 60s. Treasury and the IRS issued final regulations under news release IR-2025-91 to clarify how the age-based tiers, the Roth catch-up mandate, and related SIMPLE plan changes work together in practice, including coordination with existing limits for 403(b) and governmental 457(b) arrangements.
What the new limits mean for workers over 50
For a 62-year-old participant, the 2026 structure effectively creates three layers of salary deferrals: the standard $24,500 limit, the $8,000 general catch-up amount for anyone 50 or older, and the additional $3,250 available only between ages 60 and 63. In total, that worker could contribute $35,750 to a 401(k) plan, assuming plan rules permit all tiers and the individual has sufficient compensation to support the deferral. Those who also fund IRAs may be able to add another $7,500, subject to income and deductibility rules.
Workers considering how much to contribute should remember that catch-up contributions are optional and must be elected through their employer’s plan. The IRS explains in its guidance on catch-up contributions that these amounts sit on top of the regular deferral caps and can be made on either a pretax or Roth basis, depending on plan design and, from 2026 forward, the new Roth mandate for higher earners. Participants who expect to be in a lower tax bracket in retirement may still favor pretax savings where permitted, while those anticipating higher future rates might welcome the expansion of Roth contributions.
Plan sponsors, meanwhile, face a short implementation window. Recordkeeping systems must be updated to track age, compensation thresholds, and plan-specific Roth availability, while payroll teams will need clear instructions to avoid misdirecting catch-up dollars. Employee communication will also be critical: older workers should understand not only that their contribution room is expanding, but also that the tax character of those extra dollars may change once they cross the wage threshold. With higher limits and more complex rules arriving at the same time, 2026 is shaping up to be a pivotal year for retirement plan administration and for Americans trying to close last-minute gaps in their savings.
