Turn 50 this year and the tax code hands you a bigger shovel. On top of the standard $24,500 that any worker can defer into a 401(k) in 2026, savers who are 50 or older get an extra $8,000 of catch-up room. Turn 60, 61, 62, or 63 this year and the shovel gets bigger still: $11,250. Those figures come from the IRS cost-of-living announcement for 2026, released last November.
Catch-up contributions exist for a simple reason: the years between 50 and retirement are usually the years of peak earnings and falling expenses, the mortgage shrinking, the kids launched. Congress built extra tax-advantaged space into exactly that window. This year the rules got both more generous and, for higher earners, more complicated. Here is the full map.
The basic catch-up at 50
The regular catch-up applies to 401(k)s, 403(b)s, most 457 plans, and the federal Thrift Savings Plan. For 2026 it is $8,000, up from $7,500 last year, bringing the total employee deferral ceiling to $32,500 for anyone 50 or older. Eligibility is generous on timing: you qualify for the entire calendar year in which you turn 50, so a December birthday unlocks the room in January. The IRS covers the mechanics on its catch-up contributions page.
IRAs have their own, smaller catch-up. For 2026 it is $1,100 on top of the $7,500 base limit, the first increase after more than a decade stuck at $1,000. SIMPLE IRA plans, common at small employers, have separate catch-up amounts listed in IRS Notice 2025-67.
The 60 to 63 super catch-up
The SECURE 2.0 law created an enhanced catch-up for workers who reach age 60, 61, 62, or 63 during the calendar year. In workplace plans, those savers can contribute $11,250 of catch-up money in 2026 instead of $8,000. Add the base limit and a 62-year-old can defer up to $35,750 of salary this year.
The window closes as abruptly as it opens. In the year you turn 64, you revert to the regular catch-up amount. Congress framed it as a last-lap sprint: four years, late in a career, when many people finally have maximum cash flow. Note that eligibility keys off the age you reach during the year, so someone turning 60 in December 2026 gets the full enhanced amount for all of 2026, while someone turning 64 in January does not.
One caveat: plans are not required to offer the enhanced amount, though most large ones do. Check your plan documents or ask your administrator before you count on it.
New in 2026: high earners must use Roth for catch-ups
The biggest change this year is not an amount but a tax treatment. Beginning in 2026, if your Social Security wages from your employer exceeded $150,000 in the prior year, any catch-up contributions you make to that employer’s plan must be designated Roth contributions, made with after-tax dollars. This requirement, another piece of SECURE 2.0, was originally slated for 2024, but the IRS granted a two-year transition period that has now ended.
What does that mean in practice? You lose the immediate tax deduction on your catch-up dollars. In exchange, those dollars and all their growth come out tax-free in retirement, since Roth money follows Roth rules. For some savers that is a bad trade; for others, especially those who expect substantial retirement income, it is arguably a better one. Either way, it is not optional if you are over the wage threshold.
There is a sharper edge for people whose plans lack a Roth feature: under the rule, a plan with no Roth option cannot accept catch-up contributions from workers above the wage threshold at all. That has pushed employers to add Roth features, but if yours has not, your catch-up room may be frozen this year. The wage test looks only at pay from the employer sponsoring the plan, and it is indexed, so the $150,000 line will move over time.
What this looks like in a paycheck
Suppose you are 61, earning $120,000, and want to use every dollar of room. The base limit plus the enhanced catch-up totals $35,750, which is just under 30 percent of pay. Most plans let you set separate elections for regular and catch-up deferrals, and because your prior-year wages sit below $150,000, you may choose pretax or Roth for all of it.
Now suppose you earned $180,000 last year. Your first $24,500 of deferrals can still be pretax if you like, cutting your current tax bill. The catch-up layer above that must be Roth. Payroll systems generally flip this automatically, but early-year pay stubs are worth checking, since a miscoded catch-up can create paperwork headaches at tax time.
Do not let the labels intimidate you
Strip away the acronyms and the message of the catch-up rules is plain: after 50, the government lets you shelter more, and between 60 and 63 it lets you shelter the most of your working life. Even a partial catch-up matters. An extra $4,000 a year for the decade before retirement is $40,000 of contributions, plus whatever the market adds, in accounts your future self will thank you for. The room expires every December 31, and unused space never rolls forward. If the cash flow exists, this is the season of life to use it.
