Retirement savers who have reached their 50s gained a little more room to shelter income in 2026. The standard limit on elective deferrals to a 401(k) climbed to $24,000, up from $23,500 the year before, and workers who are 50 or older can layer an additional catch-up contribution on top of that base. Together the two figures let an older worker route far more into a workplace plan than a younger colleague can, a gap that widens in exactly the years when retirement is closest and paychecks are often at their peak.
What the 2026 limits actually add up to
The base elective deferral limit for 401(k) plans rose to $24,000 for 2026, and the same ceiling applies to 403(b) plans, most 457 plans, and the federal Thrift Savings Plan. That figure covers only the money a worker chooses to defer from salary; it does not include any matching contribution an employer adds, which rides on top under a separate, higher overall cap.
The age-50 catch-up contribution is $7,500 in 2026. Added to the $24,000 base, it lets a worker who is 50 or older defer up to $31,500 of salary into a workplace plan for the year. The catch-up is available to anyone who reaches age 50 by the end of the calendar year, even someone turning 50 in December, and it applies per person, so a married couple who both work and both qualify can each use the full amount.
The $500 bump from 2025’s $23,500 limit, confirmed in the agency’s 2026 limit announcement, is modest on its own, but it stacks with the catch-up to move the ceiling meaningfully for older savers. The 401(k) limit is also separate from the IRA contribution limit, which carries its own much lower cap and its own catch-up; a worker can contribute to both a workplace plan and an IRA in the same year, subject to each account’s rules and any deductibility limits tied to income. The elective-deferral ceiling also applies per person across plans rather than per plan, so a worker who changes jobs midyear or pays into two employers’ plans at once must track the combined total, since the limit follows the individual and not the account.
The extra room is not automatic. A worker has to actively raise the payroll deferral to capture it, since most plans default to a flat percentage or dollar amount that stops well short of the ceiling. Reaching the $31,500 total generally means adjusting the contribution election with the plan administrator, and a saver who waits until late in the year may not have enough remaining paychecks to spread the higher amount across.

The 60-to-63 super catch-up is a different, larger break
The $7,500 figure is the standard catch-up, but it is not the only one. Under the SECURE 2.0 law, workers between ages 60 and 63 are allowed an even higher catch-up limit, a provision often called the super catch-up that exceeds the regular amount for that narrow age band. It is a separate rule with its own ceiling, and it does not change the standard $7,500 catch-up that applies from age 50 onward.
The distinction matters for planning. A 52-year-old and a 61-year-old both clear the age-50 threshold, but only the older worker can reach into the larger super catch-up window, and only for the handful of years it covers. Once a worker turns 64, the higher amount no longer applies and the contribution reverts to the ordinary catch-up. The provision is also plan-dependent: a workplace plan has to offer the higher limit for a participant to use it, so eligibility rests on age, the tax year, and whether the specific plan has adopted the feature. Savers weighing how aggressively to fund a plan in their final working years should confirm which limit fits their age for the specific tax year.
Why the extra room matters most in the final working years
The elective deferral limit and the catch-up exist because the years just before retirement are when many workers can finally afford to save aggressively. Mortgages are often smaller, children are frequently independent, and earnings tend to peak, so the ability to defer $31,500 rather than $24,000 can measurably change an ending balance even when there is little time left for it to compound.
For workers whose employers match contributions, the priority order still starts with capturing the full match, since that is an immediate return no catch-up can rival. Beyond the match, the higher 2026 ceiling gives dedicated savers additional tax-advantaged space that would otherwise land in a taxable account, and the catch-up is most valuable to those already contributing near the base limit who want somewhere to put more.
The trade-off is that traditional deferrals lower taxable income now but are taxed on the way out in retirement, while the same room used in a Roth 401(k) is taxed now and comes out tax-free later. Either way, the 2026 increase hands older workers a larger container, and the Internal Revenue Service confirms the base limit, the $7,500 catch-up, and the combined $31,500 total on its 2026 contribution-limit pages. The saver’s remaining task is simply to set a deferral high enough to use it.
