The IRS has released its annual inflation adjustments, and anyone saving for retirement through a workplace plan gets a bigger bucket to fill next year.
For 2025, the elective deferral limit on a 401(k), 403(b), and most 457 plans rises to $23,500, up from $22,500 in 2024.
That's an extra $1,000 you're allowed to stash away before taxes, and it's the kind of quiet raise most workers never notice.
Catch-up contributions for savers 50 and older stay at $7,500, which means the total for that group lands at $31,000.
But there's a wrinkle worth knowing: a newer "super catch-up" kicks in for people aged 60 through 63, letting them contribute an additional $11,250 instead of the standard $7,500.
That provision came out of the SECURE 2.0 law, and 2025 is the first year it fully applies.
On the employer side, the total amount that can go into a defined contribution plan — your money plus any company match — climbs to $70,000, or $77,500 if you qualify for catch-up contributions.
That ceiling matters most for high earners who max out their own deferrals and still have room for profit-sharing or matching dollars.
Because the limit is a moving target that quietly shapes how much of your paycheck you can shield from taxes.
If you got a raise this year and did nothing else, bumping your contribution percentage by even one or two points could keep more of that money working for you instead of going to Uncle Sam.
Payroll systems usually let you change your deferral at any time, though some employers only allow updates during open enrollment.
There's also a deadline quirk people trip over.
If you want the money counted for 2025, it generally has to come out of your paychecks during 2025.
Unlike an IRA, you can't write a check in April to top off last year's 401(k).
Miss the payroll window and the chance is gone.
A few practical moves to consider before January.
First, check whether your employer matches contributions and how much you need to put in to capture the full match — that's free money most people leave on the table.
Second, if you're anywhere near the new limit, recalculate your per-paycheck number so you don't max out in October and lose match dollars in November and December.
Third, if you're 60 to 63, confirm with HR that your plan actually supports the higher catch-up, since not every employer has updated its systems yet.
None of this requires a financial advisor or a spreadsheet marathon.
Log into your plan's website, look at your current contribution rate, and ask one question: can I afford to add one more percent this year?
For a worker earning $60,000, one percent is about $12 a week before taxes.
That's a couple of coffees, and it compounds for decades.
The limits go up because inflation goes up, but your paycheck doesn't automatically follow.
The people who benefit most from these annual adjustments are the ones who actually act on them.
My take: treat the new limit as a nudge, not a to-do list item you'll get to someday.
Final Thoughts
Even a small increase now beats a perfect plan you never start.
