American workers saving for retirement got another boost from the IRS, and it's bigger than many expected.
The 401(k) elective deferral limit for 2025 rises to $23,500, up from $22,500 in 2024.
That's a $1,000 increase workers can funnel into tax-advantaged retirement accounts next year.
The catch-up contribution rules also shifted in a way that could trip up higher earners.
Workers 50 and older can still add an extra $7,500 on top of the base limit, bringing their total to $31,000.
But a new "super catch-up" provision allows those aged 60 through 63 to contribute an additional $11,250 instead of $7,500—a change buried in SECURE 2.0 that few savers have noticed.
Because most people set their contribution percentage once and never revisit it.
If you're contributing a flat dollar amount, inflation quietly erodes the real value of your savings each year.
Bumping your rate by even 1% of salary can add tens of thousands of dollars over a career.
Employer match formulas make the stakes higher.
A typical 50% match up to 6% of salary means anyone contributing less than that threshold is leaving free money on the table.
With the new limit, a worker earning $80,000 could shelter nearly 30% of their gross pay in a 401(k), depending on plan rules.
Traditional 401(k) contributions reduce taxable income today, which can lower your bracket or protect eligibility for credits like the Child Tax Credit.
Roth 401(k) contributions don't lower current taxes but grow tax-free, and more employers now offer both options side by side.
Maxing out at $23,500 works out to about $904 per paycheck if you're paid biweekly—a stretch for many households already squeezed by rent and grocery bills.
Financial planners typically suggest capturing the full employer match first, then increasing contributions gradually with each raise.
One group needs to pay extra attention: high earners.
A provision in SECURE 2.0 requires catch-up contributions to be made as Roth contributions starting in 2026 for those earning above $145,000 (indexed).
That means a future tax bill instead of a current deduction, which changes the math for late-career savers.
Contribution limits are annual and use-it-or-lose-it.
You can't go back in January and fill up last year's bucket.
Payroll systems often cap contributions automatically, so anyone trying to hit the max should check their plan's per-paycheck limits before December.
Our take: the higher limit is genuinely good news, but it only helps people who act on it.
The smartest move is logging into your plan portal this week, checking your current contribution rate, and bumping it up—even by a single percentage point.
Final Thoughts
Small, automatic increases beat heroic January resolutions every time.
