Your 401(k) is one of the most powerful wealth-building tools you have — but only if you understand the limits and use them well. Every year the IRS sets how much you can contribute, and for 2026 the numbers went up. Here’s exactly what you can put in, plus the smart way to use those limits to lower your taxes and build real retirement savings.
The 2026 401(k) contribution limits
For 2026, the IRS raised the limits. Here’s what you can contribute:
| Who | 2026 limit |
|---|---|
| Standard (under 50) | $24,500 |
| Catch-up (age 50+) | extra $8,000 (total $32,500) |
| “Super” catch-up (ages 60–63) | extra $11,250 (in place of the $8,000) |
So if you’re under 50, you can contribute up to $24,500 of your own money in 2026. At 50 or older, you can add an $8,000 catch-up for $32,500 total. And a special higher catch-up of $11,250 applies for ages 60–63. The IRS confirms these figures at irs.gov.
Don’t forget the employer match
The limits above are your contributions. Many employers also match part of what you put in — for example, matching 50% of your contributions up to 6% of your salary. That match is free money on top of your own limit, and it’s the single best reason to contribute at least enough to capture the full match. If your employer offers a match and you’re not capturing all of it, you’re leaving free money on the table.
Why contributing lowers your taxes
A traditional 401(k) contribution comes out of your paycheck before tax, which lowers your taxable income for the year. Put in $10,000, and you’re taxed on $10,000 less income — so you save on taxes and build retirement savings at the same time. (A Roth 401(k), if your plan offers one, works the opposite way: you pay tax now, but withdrawals are tax-free later — similar to a Roth IRA.)
A note for high earners (2026 change)
There’s a new rule starting in 2026: if you’re 50+ and your prior-year wages with your employer exceeded $150,000, your catch-up contributions generally must be made on a Roth (after-tax) basis. It’s a detail that mainly affects higher earners — worth knowing if that’s you.
How to actually use the limits
You don’t have to max out to win. A sensible order of priorities many people follow:
1. Contribute enough to get the full employer match — free money, do this first.
2. Consider a Roth IRA next for tax-free growth (the 2026 IRA limit is $7,500).
3. Return to the 401(k) and increase contributions toward the limit as your budget allows.
Even small increases compound enormously over a career. Bumping your contribution by 1% of salary is nearly painless now and can mean tens of thousands more later — see the math in the Compound Interest Calculator.
Where the money to contribute comes from
Free up room in your budget to raise your contributions. A quick pass through the 50/30/20 Budget Calculator often reveals money in the “wants” bucket you could redirect to retirement. And because contributions lower your taxable income, the hit to your take-home pay is smaller than the amount you contribute — see how in the Take-Home Pay Calculator.
Frequently asked questions
What is the 401(k) contribution limit for 2026?
$24,500 if you’re under 50. Those 50+ can add an $8,000 catch-up ($32,500 total), and ages 60–63 get a higher $11,250 catch-up.
Does the employer match count toward my limit?
No — your $24,500 limit is for your own contributions. The employer match is on top of that, which is why it’s such a good deal.
Should I max out my 401(k)?
First capture the full employer match, then weigh a Roth IRA, then increase 401(k) contributions toward the limit as your budget allows. Maxing out is great if you can afford it.
Does contributing lower my taxes?
Yes — traditional 401(k) contributions are pre-tax, lowering your taxable income for the year. A Roth 401(k) is after-tax but grows tax-free.
The takeaway
For 2026, you can contribute up to $24,500 to a 401(k) (plus an $8,000 catch-up at 50+, or $11,250 at ages 60–63). The smartest moves: always capture the full employer match first (it’s free money), use the pre-tax contributions to lower your taxable income, and raise your contribution rate over time. Find the room in your budget with the 50/30/20 Budget Calculator and watch it grow in the Compound Interest Calculator.
