How Much Am I Allowed to Contribute to My 401(k) in 2025 — Updated Limits, Rules, and Smart Strategies

If you’re planning your retirement savings for the upcoming year, one of the biggest questions you might have is: how much am I allowed to contribute to my 401(k)? The Internal Revenue Service (IRS) recently announced new contribution limits for 2025, and there are some important changes every U.S. worker should know about — especially those nearing retirement age.

These updates affect millions of Americans participating in employer-sponsored retirement plans, so understanding the rules can help you maximize your savings and take full advantage of available tax benefits.


2025 401(k) Contribution Limits at a Glance

For 2025, the IRS has slightly increased the contribution limits for 401(k) plans to account for inflation. Here’s what that means for you:

  • Standard Employee Contribution Limit (Under Age 50): $23,500
  • Catch-Up Contribution Limit (Age 50 and Over): $7,500
  • Super Catch-Up Limit (Age 60–63): $11,250 (for eligible workers under the SECURE 2.0 Act)
  • Total Combined Limit (Employee + Employer Contributions): $70,000

These new limits apply to 401(k), 403(b), most 457 plans, and the federal Thrift Savings Plan (TSP).

In simple terms, if you’re under 50, you can save up to $23,500 of your salary in your 401(k) in 2025. If you’re 50 or older, you can contribute an additional $7,500, bringing your total to $31,000. And if you’re between 60 and 63, the new “super catch-up” provision allows you to go even higher — up to $34,750.


How Catch-Up and Super Catch-Up Contributions Work

If you’re age 50 or older, the IRS allows you to make extra “catch-up” contributions to your 401(k). These contributions are designed to help older workers make up for lost time and boost their retirement funds as they approach retirement.

For workers aged 60 to 63, the new “super catch-up” rule introduced under the SECURE 2.0 Act gives an even higher limit — 150% of the regular catch-up amount. That means you can add an extra $11,250 in contributions in 2025.

However, there’s a new condition starting in 2026: workers earning over $145,000 must make their catch-up contributions as Roth contributions (after-tax), rather than pre-tax. This means the money will grow tax-free, but you won’t get an immediate tax deduction.


How Employer Contributions Fit In

Your personal contribution limit is separate from what your employer can add. Employers often match a portion of what you contribute — for example, 50% of the first 6% of your salary.

In 2025, the total combined contribution limit — including both your own contributions and any employer match — is $70,000 (or $77,500 if you’re eligible for catch-up contributions).

Here’s an example:

Contribution Type2025 Limit
Employee (Under 50)$23,500
Catch-Up (50+)+$7,500
Super Catch-Up (60–63)+$11,250
Employer MatchUp to combined total of $70,000

This total cap ensures that your total annual contributions — whether from you, your employer, or both — don’t exceed IRS-set thresholds.


Why You Should Max Out Your 401(k) Contributions

Maxing out your 401(k) can significantly improve your long-term financial security. Here’s why contributing as much as you’re allowed makes sense:

  1. Tax Benefits — Traditional 401(k) contributions are made pre-tax, reducing your taxable income. This means you pay less in federal taxes now and let your money grow tax-deferred.
  2. Free Money from Employer Matching — If your company matches part of your contributions, that’s essentially a guaranteed return on investment.
  3. Compound Growth — The earlier and more consistently you contribute, the more time your money has to grow through compounding.
  4. Automatic Savings — Contributions are deducted directly from your paycheck, making it easy to stay disciplined with retirement saving.

Even if you can’t contribute the maximum, increasing your contributions by even 1% each year can make a big difference over time.


How to Decide How Much You Should Contribute

While the IRS sets the maximum you’re allowed to contribute, the “right” amount for you depends on your income, expenses, and financial goals.

Here are a few benchmarks:

  • Start with your employer match: Always contribute at least enough to get the full match — that’s free money you shouldn’t leave behind.
  • Aim for 10–15% of your income: Financial advisors generally recommend saving 15% of your income for retirement, including employer contributions.
  • Increase contributions gradually: If you can’t afford to max out now, increase your contributions by 1% every few months or after each raise.

The Role of Roth 401(k) Contributions

Most employers now offer both traditional and Roth 401(k) options. The difference lies in when you pay taxes:

  • Traditional 401(k): Contributions are made pre-tax. You get a tax break now, but withdrawals in retirement are taxed.
  • Roth 401(k): Contributions are made after-tax. You pay taxes upfront, but withdrawals in retirement are tax-free.

For younger savers or those expecting higher tax rates in retirement, the Roth 401(k) can be especially beneficial.


Important IRS Rules to Remember

  1. Multiple 401(k) Plans:
    If you change jobs or have multiple employers, your total combined employee contributions cannot exceed the annual limit ($23,500 for 2025).
  2. Income Limits for Catch-Up Contributions:
    Starting in 2026, high-income earners (over $145,000) will be required to make catch-up contributions as Roth (after-tax).
  3. Nondiscrimination Testing:
    If you’re a highly compensated employee (HCE), your plan must pass IRS testing to ensure fairness. If it fails, your excess contributions may be refunded.
  4. Withdrawals:
    With few exceptions, withdrawals made before age 59½ are subject to income tax and a 10% penalty.

Strategies to Maximize Your 401(k) in 2025

If you want to take full advantage of the 2025 contribution limits, here are practical ways to optimize your 401(k):

  • Automate your increases: Many plans allow you to automatically raise contributions by 1% each year.
  • Split between Roth and traditional: Diversify your tax exposure by using both options.
  • Rebalance regularly: Review your investments quarterly or annually to maintain your preferred risk level.
  • Avoid early withdrawals: Keeping funds invested allows them to grow longer through compounding.
  • Stay informed: Revisit your contributions every year as the IRS adjusts limits for inflation.

Why the 2025 Increase Matters

Although the $500 increase may not seem like much, over time it can make a real difference. Contributing just $500 more each year could grow to more than $80,000 after 30 years, assuming a 7% annual return.

This incremental growth, combined with employer matching and compound interest, shows why staying up to date on contribution limits can pay off significantly in the long run.


Final Thoughts

Knowing how much you’re allowed to contribute to your 401(k) each year is the foundation of smart retirement planning. For 2025, the new limits — $23,500 for most workers and up to $34,750 for those 60–63 — offer even greater opportunities to build wealth and take advantage of tax benefits.

Whether you’re just starting out or nearing retirement, the key is consistency. Every dollar you contribute today brings you one step closer to financial freedom tomorrow.
