The four-year 401(k) catch-up window at 60–63
For four calendar years only, the catch-up limit on a 401(k) or similar workplace plan jumps well past the standard age-50 amount — but only if your plan permits it, and only if you know to ask.
Everyone 50 and older can already put more into a 401(k) than younger workers can. Fewer people know there is a second, larger step up — available only during the calendar years you are 60, 61, 62 or 63, and only if your employer’s plan specifically allows it.
| Standard elective deferral limit | $24,500 — what anyone under 50 can contribute. |
|---|---|
| Standard catch-up, age 50+ | An additional $8,000, for a total of $32,500. |
| Super catch-up, ages 60–63 | An additional $11,250 instead of the standard catch-up, for a total of $35,750. |
| The window | Only the calendar years you turn 60, 61, 62 or 63. Turn 64, and the limit drops back to the standard $8,000 catch-up. |
| Plan availability | The higher catch-up must be specifically permitted under the employer’s plan — it is not automatic just because the plan allows the standard 50+ catch-up. Ask your plan administrator directly. |
| The Roth requirement | For 2026, participants whose prior-year FICA wages from the plan sponsor exceeded $150,000 (indexed) generally must make all of that year’s catch-up contributions as designated Roth contributions, not just the extra amount above the standard catch-up. |
| Not only 401(k)s | The same age window, dollar figures and Roth threshold also apply to 403(b) plans, governmental 457(b) plans, and the federal Thrift Savings Plan. SIMPLE plans have their own, smaller catch-up figures. |
Why the window is exactly four years
SECURE 2.0 set the higher catch-up specifically for the calendar years someone is age 60 through 63 — not a running “60 and older” category the way the standard catch-up works. Turn 64 partway through a year and that year still counts at the higher limit; the following year, once you’ve turned 64, the amount reverts to the ordinary $8,000 catch-up. There is no extending it and no repeating it — four specific tax years, tied to your birth year, and then it’s gone.
At the 2026 figures, that is $3,250 more in an eligible year than the standard 50+ catch-up alone allows — a meaningful amount in the years right before retirement, when income is often at its highest and the runway to grow it is shortest. These limits are indexed for inflation and reset most years, so the four-year total will not simply be four times this year’s difference; what stays constant is the shape of the rule, not this specific dollar figure.

Read it →This is not automatic and it is not universal. It exists only in plans that chose to offer it, for four specific years, and nobody is required to tell you it applies to you.
The Roth trap specifically
The income threshold is not about your total household income or your overall wealth — it is specifically wages from the employer sponsoring the plan, in the prior calendar year. Cross $150,000 (indexed annually) in wages from that employer, and every dollar of catch-up contribution that plan year — the standard portion and the extra super catch-up alike — has to go in as Roth, meaning taxed now rather than deferred. This is a plan-level rule, not something you elect; get the mechanics wrong and a plan can reject the contribution rather than quietly converting it.
- Ask your plan administrator directly whether your 401(k), 403(b), 457(b) or TSP account offers the age 60–63 super catch-up. It is not universal, and it will not be flagged for you automatically.
- Check whether your prior-year wages from that specific employer put you over the $150,000 Roth-mandate threshold — this determines whether your catch-up contributions land pre-tax or Roth.
- If you turn 60 this year, mark your calendar: this is the first of your four eligible years, and the amount you can contribute changes again the year you turn 64.
- If you have multiple employers or a job change during this window, the eligibility and wage-threshold questions reset with each new employer’s plan — confirm the rule with each one rather than assuming continuity.
- This applies to elective deferrals you choose to contribute, not to employer matching or profit-sharing contributions, which follow separate limits.
The four-year shape of this is what makes it easy to miss — it is not a standing feature of turning 60 the way the regular catch-up is a standing feature of turning 50. It opens once, runs for four years exactly, and closes on schedule whether or not anyone used it.

He started The Second Half Guide after noticing that most writing aimed at people his age was either talking down to him or quietly selling him something, and that the plain facts — the dates, the thresholds, the dollar figures — were somehow the hardest part to find.
