The IRS has raised the 401(k) contribution limit for 2026, and if you're not paying attention, you could leave free money sitting on the table.
The new elective deferral cap for workplace retirement plans climbs to $24,500, up $500 from 2025.
Catch-up contributions for workers 50 and older stay at $7,500, putting the total for that group at $32,000.
That extra $500 isn't going to change anyone's life on its own.
But the bigger story is what happens when you combine a higher limit with an employer match and a few minutes of paperwork.
Most people never touch their contribution rate after their first day on the job.
A 401(k) limit isn't a target you have to hit — it's a ceiling.
If your budget is tight, bumping your rate from 4% to 5% still matters, especially if your employer matches dollar-for-dollar up to a certain point.
Anything below the match threshold is money you're walking away from.
Say you earn $65,000 and your employer matches 50% of contributions up to 6% of pay.
Contributing 6% means $3,900 of your own money and a $1,950 match.
That match is an instant 50% return before any market movement.
The math on maxing out looks different depending on your paycheck.
At $24,500 a year, you'd need to set aside roughly $943 per paycheck if you're paid twice a month.
A more realistic move is nudging your rate up by 1% each time you get a raise, so you never feel the pinch.
Also note the total cap across all your accounts.
Combined employee and employer contributions can't exceed $72,000 in 2026 for most plans, up from $70,000.
If you're a high earner with a generous match, that ceiling is the one to watch.
One more wrinkle: the catch-up rules changed for higher earners.
Workers 50 and up who earned more than $145,000 in the prior year must make catch-up contributions as Roth (after-tax) dollars if their plan allows it.
That's a shift worth checking with your HR or plan provider before December.
The easiest way to act is to log into your plan's website and raise your deferral percentage by one point.
Waiting until the end of the year means scrambling to catch up, and many payroll systems make that more complicated than it needs to be.
Our take: the higher limit is good news, but the real win is the match, not the cap.
Most Americans should focus on capturing every dollar their employer offers before chasing the maximum.

A modest bump today beats a perfect plan you never get around to.
