Catch-up contributions have let workers 50 and older set aside extra retirement savings for years, but a newer provision carved out an even wider lane for a narrower slice of that group. Workers who land in a specific four-year age window now qualify for a bigger boost than everyone else covered by the standard rule, a distinction that can meaningfully change how someone times retirement contributions in the final stretch before leaving the workforce.
The Standard Catch-Up Rule as a Starting Point
Under longstanding IRS guidance, workers age 50 or older can make catch-up contributions to a 401(k), 403(b), SARSEP, or governmental 457(b) plan on top of the regular annual deferral limit. That baseline rule has applied broadly for years and remains available to any eligible worker from age 50 onward, regardless of how close they are to retirement.
The newer provision does not add a second contribution on top of that baseline catch-up. Instead, it replaces the catch-up figure itself with a larger one for a specific age band, effectively creating two tiers of catch-up amounts depending on exactly how old a worker is in a given calendar year, while the underlying regular deferral limit stays the same for everyone.

Why Ages 60 Through 63 Get Special Treatment
Under a change made in SECURE 2.0, a higher catch-up contribution limit applies to employees who turn 60, 61, 62, or 63 in a calendar year, starting in 2025, for those participating in most 401(k), 403(b), and governmental 457 plans, as well as the federal government’s Thrift Savings Plan. The IRS confirms the elevated limit remains in effect for the 2026 plan year, meaning it is not a one-time adjustment but an ongoing feature of the tax code for workers who fall into that age range.
A parallel version of the increase applies to SIMPLE IRA and SIMPLE 401(k) plans for the same 60-to-63 age band, again replacing the standard SIMPLE plan catch-up figure with a larger one for those specific ages rather than adding a separate contribution alongside it.
The Window Closes at 64
The expanded catch-up tier is tied strictly to the calendar year in which a worker turns 60, 61, 62, or 63, which means eligibility is temporary by design. A worker who turns 64 during the year returns to the standard age-50 catch-up amount rather than continuing to receive the larger figure, so the enhanced tier functions as a four-year window rather than a permanent upgrade once reached. Eligibility for a given year is based on the age a worker reaches by December 31 of that year, so a worker who turns 60 partway through the year still qualifies for the full elevated figure for that entire year rather than a prorated amount tied to the exact birthday.
That structure rewards workers who plan around the specific years they qualify, since missing the window by not increasing payroll deferrals during those calendar years cannot be made up retroactively once the worker ages out of the range.
Why the Change Exists in the First Place
The enhanced tier was built into SECURE 2.0 as a targeted acknowledgment that the years immediately before typical retirement are often when a worker has the most capacity to save, after a mortgage is paid down, children are grown, or other major expenses have eased. Rather than raising the catch-up amount for every worker 50 and older, lawmakers narrowed the larger increase to the final stretch before many people leave the workforce, on the theory that this is when an extra push toward tax-advantaged savings does the most good.
That design also explains why the increase is not permanent for an individual worker. Once someone ages out of the 60-to-63 window, the logic behind the larger figure no longer applies in the same way, so the catch-up amount steps back down to the standard age-50 level rather than staying elevated for the remainder of a person’s working years.
Confirming Eligibility Through a Plan Administrator
Not every workplace plan is required to implement the higher catch-up tier automatically, so a worker turning 60 through 63 should confirm directly with a plan administrator or payroll department that the elevated limit has been applied to their deferral elections rather than assuming it happens by default. Plans also differ in how quickly they update payroll systems to reflect the higher figure at the start of a new calendar year.
For someone in the final years of full-time work, the distinction between the standard and enhanced catch-up tiers can represent a meaningful difference in how much gets sheltered from current-year taxes and redirected into tax-advantaged growth before retirement begins, which is precisely the stretch of a career when many households have the most disposable income to devote to savings.
