Workers 55 and older can set aside significantly more in a 401(k) than younger savers, thanks to catch-up contributions built into federal tax law. For 2026, that means a standard catch-up of $8,000 on top of the regular deferral limit, with an even larger option for those turning 60 to 63. The rules changed meaningfully for 2026, both in the dollar amounts and in how high earners must contribute. Understanding the new limits, the age brackets that unlock them, and a new Roth requirement for higher-paid workers determines how much of this opportunity a given worker can actually use.

What's the 2026 contribution limit for workers over 55?
The IRS set the standard 401(k) elective deferral limit at $24,500 for 2026, up from $23,500 in 2025, under Notice 2025-67. That base limit applies to every worker regardless of age, and it also covers 403(b) plans and most 457(b) government plans.
Workers age 50 and older get an additional standard catch-up contribution on top of that base limit. For 2026, the standard catch-up rises to $8,000, up from $7,500 in 2025, which brings a 50-plus worker's total allowable 401(k) contribution to $32,500, according to CPA Practice Advisor. This catch-up is available to any worker who turns 50 at any point during the year, not only those 55 and older, so the "after 55" window is really a continuation of an eligibility period that began five years earlier.
The larger catch-up for ages 60 to 63
Beyond the standard catch-up, SECURE 2.0 created a bigger "super" catch-up contribution for a specific age band. Employees who turn 60, 61, 62, or 63 at any point in the year qualify for an $11,250 catch-up in 2026, the same dollar amount as 2025, because this figure is indexed separately from the standard catch-up limit, according to Kiplinger. Combining the pieces, a worker in that four-year window who earns under the relevant wage threshold could defer up to $35,750 into a 401(k) in 2026: the $24,500 base limit plus the $11,250 super catch-up, per CPA Practice Advisor. That's more than $3,000 above what a 50-to-59-year-old or a 64-plus worker can contribute using the standard catch-up alone. The super catch-up is not automatic once a worker hits 60.
A 401(k) plan sponsor must affirmatively adopt the feature for employees to use it, so an eligible worker's access depends on whether their employer's plan offers it, Kiplinger reports. Workers should check with HR or their plan administrator rather than assuming the higher limit applies. The window also closes on schedule. A worker who turns 64 during the plan year loses eligibility for the $11,250 super catch-up and reverts to the standard $8,000 catch-up for that year, per Kiplinger. Timing matters: the eligibility test is based on the age reached during the calendar year, not a birthday cutoff mid-year.
A new Roth requirement for higher earners
Starting in 2026, a SECURE 2.0 provision requires certain high earners to make their catch-up contributions as after-tax Roth money instead of pre-tax. The rule applies to any employee age 50 or older whose prior-year FICA wages from that employer exceeded $150,000 — the 2025 wages, adjusted for inflation and set in Notice 2025-67 — according to NYSSCPA. The IRS issued final regulations on this requirement in September 2025, after delaying the original 2024 effective date to give employer payroll and recordkeeping systems time to adapt, according to ADP.
That delay is why many workers are only now encountering the change. The consequence for workers whose plan doesn't offer a Roth option is more severe than a tax-treatment switch. The final regulations bar affected high-wage participants from making any catch-up contributions at all in a plan with no Roth feature, starting in 2026, rather than letting them keep contributing pre-tax, per ADP. A worker over the $150,000 threshold whose employer hasn't added a Roth option could lose access to the catch-up entirely until the plan adds one.

How the pieces fit together by age and income
A worker's actual limit depends on three separate checks: their age during the calendar year, whether their plan has adopted the super catch-up feature, and whether their prior-year wages trigger the Roth-only requirement. Checking a 401(k) plan's summary plan description or asking a benefits administrator directly is the only reliable way to confirm which of these apply, since plan design and payroll history vary by employer.
- Age 50-59, under the wage threshold: base limit of $24,500 plus an $8,000 standard catch-up, for $32,500 total, contributed pre-tax or Roth as the plan allows.
- Age 60-63, under the wage threshold, plan offers the super catch-up: base limit of $24,500 plus an $11,250 super catch-up, for up to $35,750 total.
- Age 64 and older: reverts to the $24,500 base plus the $8,000 standard catch-up, for $32,500 total.
- Any age 50+, prior-year wages from that employer above $150,000: the catch-up portion must go into Roth, and is unavailable at all if the plan has no Roth option.
IRA catch-ups moved too
The catch-up increase isn't limited to 401(k)s. IRA catch-up contributions for savers age 50 and older also rose for 2026, to $1,100 from $1,000, lifting the total IRA contribution limit for that group to $8,600, according to PSCA. A worker maxing out both a 401(k) and an IRA in 2026 can factor this increase into a combined savings plan, since the two account types have separate limits that don't offset each other.
Frequently Asked Questions
Does the super catch-up for ages 60-63 require anything extra from the worker?
No extra paperwork from the worker, but the employer's plan must have adopted the feature; workers should confirm with their plan administrator that it's offered.
What happens to the super catch-up contribution amount when a worker turns 64?
It drops back to the standard $8,000 catch-up for that plan year, since the $11,250 super catch-up only applies to ages 60 through 63.
Who is affected by the new Roth-only catch-up rule?
Employees 50 or older whose prior-year FICA wages from that employer exceeded $150,000, a threshold set in IRS Notice 2025-67 and adjusted for inflation going forward.
