401(k) Contribution Limits 2026: Full Guide

The 401(k) is the most important retirement savings vehicle for most American workers, and 2026 brings higher contribution limits, a new "super catch-up" provision, and a total annual addition limit that allows even more total savings. Here's everything you need to know to maximize your 401(k) in 2026.

2026 Employee Contribution Limits

• Under age 50: $24,500 maximum employee contribution
• Ages 50-59 or 64+: $24,500 + $8,000 catch-up = $32,500 maximum
• Ages 60-63: $24,500 + $11,250 super catch-up = $35,750 maximum

The super catch-up provision for ages 60-63 is a feature introduced by the SECURE 2.0 Act, giving workers a final push to boost retirement savings before the typical retirement window.

Total Annual Addition Limit

• 2026 total annual addition limit: $70,000 (under age 50)
• With catch-up (50-59, 64+): $78,000
• With super catch-up (60-63): $81,250

This limit matters if your employer offers generous matching or profit sharing, or if your plan allows after-tax contributions for the "mega backdoor Roth" strategy.

How Much Is the 401(k) Employer Match Worth?

The most common employer match formulas:

• Dollar-for-dollar up to 3%: Employer contributes $1 for every $1 you contribute, up to 3% of salary
• 50 cents per dollar up to 6%: Effective 3% match
• Dollar-for-dollar up to 6%: The most generous common match

On a $100,000 salary with a 50% match up to 6%, you contribute $6,000/year and get $3,000 free. That's an immediate 50% return on your money.

Traditional vs. Roth 401(k)

Many 401(k) plans now offer both options. The $24,500 limit applies to your combined Traditional and Roth contributions.

• Traditional 401(k): Contributions reduce current taxable income. You pay tax on withdrawals in retirement.
• Roth 401(k): Contributions are after-tax. Qualified withdrawals in retirement are tax-free.

If you're early in your career and in a lower bracket, Roth locks in today's low rate. At peak earnings, Traditional gives the biggest current tax break. Plan your strategy with our retirement calculator.

How to Actually Max Out Your 401(k)

• Start where you are: If currently contributing 6%, increase by 1-2% every six months
• Direct raises to your 401(k): Increase your percentage by half the raise amount when you get a raise
• Automate increases: Many plans offer automatic annual increases
• Front-load cautiously: If you max out before year-end, you may miss employer match dollars without a true-up provision

What Is the 401(k) Super Catch-Up for Ages 60-63?

At $35,750 in total employee contributions, four years of super catch-up (ages 60-63) means $143,000 in employee contributions alone. At 7% returns, those contributions could grow to $300,000+ by age 70.

Important: Starting in 2026, catch-up contributions for employees earning over $145,000 in the prior year must be made as Roth (after-tax) contributions per SECURE 2.0.

The Bottom Line

At minimum, contribute enough to capture your full employer match. Ideally, work toward maxing out the $24,500 employee limit. If you're 60-63, take full advantage of the $11,250 super catch-up.
