The IRS bumped the 401(k) contribution limit to $23,500 for 2025, up from $22,500 last year.
That extra $1,000 may not sound like much, but it quietly reshapes how much you can shelter from taxes while you're still working.
There's also a separate "super catch-up" rule that kicked in this year for workers aged 60 to 63, letting them stash an extra $11,250 instead of the standard $7,500 catch-up.
If you're under 50, your total employee contribution cap is now $23,500.
If you're 50 or older, you can add a $7,500 catch-up on top, bringing your personal limit to $31,000.
And if you happen to be 60, 61, 62, or 63 this year, that catch-up jumps to $11,250 — a change Congress slipped into SECURE 2.0 that most people have never heard of.
Here's the part that matters for your paycheck.
The total amount that can go into a 401(k) from both you and your employer — combined — rose to $70,000 for 2025, or $77,500 if you qualify for catch-up contributions.
That's the ceiling on the whole pot, not just your slice.
Most workers never come close, but high earners and anyone with a generous match should check where they stand.
A typical employer matches 50% of what you contribute, up to 6% of your salary.
If you're putting in 3% because that's what you can "afford," you're leaving free money on the table every single pay period.
Bumping to 6% often costs less than a streaming subscription and can add tens of thousands of dollars over a career.
A simple move: log into your plan's website this week and look at your current contribution percentage.
If it's below your employer's match threshold, raise it by 1% today.
Then set a calendar reminder to raise it another 1% every six months.
You will barely feel the difference in your take-home pay, but your future self will notice.
One catch to watch: starting in 2026, workers earning over $145,000 will have to make catch-up contributions as Roth dollars, meaning after-tax money.
If you're in that bracket, it's worth talking to a tax pro before the rule flips.
Also worth knowing — the limit applies per person, not per household.
Two working spouses can each contribute $23,500, which means a married couple could shelter $47,000 combined before any catch-up.
That's a detail plenty of families overlook when they're budgeting for the year.
The bottom line: a higher limit only helps if you actually use it, and the easiest win isn't maxing out — it's grabbing every dollar your employer is willing to hand you.

Check your percentage, fix the match gap, and let the rest ride.
