The IRS has raised the amount you can stash in a 401(k) next year, and the new number is big enough that it may change how you plan your paycheck.
For 2026, the employee contribution limit climbs to $24,500, up from $23,500 in 2025.
Catch-up contributions for workers 50 and older rise to $8,000, bringing the total for that group to $32,500.
That extra $1,000 may sound small, but it compounds in ways that are easy to underestimate.
Someone who adds $1,000 a year for two decades at a 7% average return could end up with roughly $40,000 more in retirement savings.
The catch is that most people never come close to maxing out, so the higher ceiling mostly matters if you're already near the top.
There's a second change that gets less attention but hits higher earners harder.
Under a rule now in effect, workers who earned more than $145,000 in the prior year must make their catch-up contributions as Roth dollars, meaning after-tax money.
If you're in that group, the $8,000 catch-up is no longer a pre-tax deduction, so your taxable income won't drop the way it used to.
That can shrink your take-home pay even if your contribution amount stays the same.
Employers are also allowed to match more.
The total cap on combined employee and employer contributions, plus forfeitures, rises to $72,000 for 2026.
If your company offers a generous match, this is the number that matters most, because it covers both your money and theirs.
For most households, the practical move isn't maxing out, it's capturing the full match.
If your employer matches 50% of contributions up to 6% of pay, contributing less than that is leaving free money on the table.
A common mistake is stretching to hit the annual limit in January and missing the match later in the year if your plan doesn't true up.
Spreading contributions evenly across all 24 or 26 paychecks avoids that trap.
Also worth checking: whether your plan offers automatic escalation, which bumps your contribution rate by 1% or 2% each year.
Enrollment data shows most people who turn it on stick with it, and they rarely miss the money because the increase lands alongside a raise.
If you got a cost-of-living bump this year, routing part of it into the 401(k) is one of the few ways to save more without feeling it.
One more thing to verify before December: your plan's deadline for changing contributions.
Many payroll systems need a week or two of lead time, so a change made on December 28 may not take effect until February.
If you're trying to hit a specific number for the tax year, check the cutoff now rather than the last week of the year. **Our take:** The rising limit is good news, but it's not a command.
For anyone juggling rent, groceries, and credit card balances, the right target is usually the match, not the maximum.
Final Thoughts
Grab the free money first, then raise your rate by a point or two when your budget allows.
