The IRS has raised the 401(k) contribution limit for 2026, and the new numbers are worth a closer look if you're trying to squeeze more into retirement before the year gets away from you.
The employee deferral limit is climbing to $24,500, up from $23,500 in 2025.
Catch-up contributions for savers 50 and older stay at $7,500, while a newer "super" catch-up of $11,250 applies to those aged 60 through 63.
That extra $1,000 may not sound like much, but it compounds.
If you invest that additional amount every year for a decade at a 7% average return, you're looking at roughly $14,000 in growth on top of the contributions themselves.
Over 20 years, the gap widens into six figures.
The total cap on combined employer and employee contributions also rose, landing at $72,000 for 2026.
That matters for people whose employers offer generous matches or profit-sharing.
If your company kicks in a percentage of your salary, you may be able to shelter far more income than the headline deferral number suggests.
A few practical notes before you bump your withholding.
First, check whether your plan offers automatic escalation, which raises your contribution rate each year on a set schedule.
Second, confirm your employer's match formula and vesting schedule so you're not leaving free money on the table.
Third, if you're 50 or older, ask your plan administrator whether catch-up contributions must now be made as Roth dollars, since a rule change is phasing in for higher earners.
One trap worth avoiding: front-loading too aggressively in January can cause you to hit the annual cap before year-end, which may cost you match dollars if your employer trues up contributions only on a per-paycheck basis.
Spreading contributions evenly across all 26 pay periods is usually the safer play.
For 2026, the numbers to remember are $24,500 for standard deferrals, $7,500 for the 50-plus catch-up, and $11,250 for ages 60 to 63.
If your budget allows, nudging your rate up by even 1% of salary starting in January is a low-effort move with a long tail.
The bottom line: a $1,000 limit increase won't change anyone's life overnight, but ignoring it quietly costs you.

Future you will not send a thank-you note, but the balance will.
