401(k) Contribution Limits Explained: What Changed for 2025–2026

As tax season rolls around in the U.S., it’s a perfect time to revisit your retirement savings strategy. One of the most important pieces of that puzzle is your 401(k) contribution limits and plan — one of the most powerful tools workers have to save for retirement. Each year, the IRS adjusts contribution limits to keep pace with inflation and help savers put away more on a tax-advantaged basis.

Whether you’re trying to maximize your contributions before the tax deadline or planning for next year, here’s a clear and up-to-date breakdown of the 401(k) limits for 2025 and 2026.

What Is a 401(k)?

A 401(k) is an employer-sponsored retirement savings plan that lets you defer a portion of your paycheck into a tax-advantaged account. You can make traditional (pre-tax) contributions, Roth (after-tax) contributions, or a mix of both (if your plan allows).

  • Traditional contributions reduce your taxable income today.

  • Roth contributions are made with after-tax dollars but grow tax-free and aren’t taxed when withdrawn in retirement under qualifying rules.

There are also catch-up contributions for older savers to help boost savings as retirement nears.

401(k) Contribution Limits for 2025

For the tax year 2025:

  • The employee elective deferral limit — the amount you can contribute from your own salary — is $23,500.

  • If you’re age 50 or older, you can make an additional catch-up contribution of $7,500.

  • Individuals ages 60–63 can make a higher “super catch-up” contribution of up to $11,250 in place of the $7,500, if their plan allows.

This means that a saver turning age 50 during 2025 could defer up to $31,000 total of their salary into their 401(k) (base limit + catch-up), or up to $34,750 if eligible for the higher age-60-to-63 catch-up.

The limit applies across all 401(k) plans combined. So if you have more than one job with separate plans, you still can’t exceed this total.

401(k) Contribution Limits for 2026

For the tax year 2026, the IRS increased several key 401(k) limits:

  • The employee contribution limit rises to $24,500 — up $1,000 from 2025.

  • The standard catch-up amount for individuals age 50 and older increases to $8,000.

  • The higher catch-up limit for people ages 60–63 remains $11,250 (plan dependent).

So in 2026:

  • Someone under age 50 can defer up to $24,500 of their salary.

  • A saver age 50 or older could contribute up to $32,500 total (standard catch-up).

  • Individuals age 60–63 who qualify for the super catch-up could defer up to $35,750 or more (if their plan supports the higher limit).

These figures include both traditional and Roth employee contributions combined.

Mandatory Roth Catch-Up for Higher Earners (2026 Rule Change)

A significant rule under the SECURE 2.0 Act affects how catch-up contributions are treated:

  • Starting in 2026, if your prior year wages from your employer exceed a specified threshold (indexed around $150,000), your catch-up contribution must be designated as Roth (after-tax) rather than pre-tax.

  • This means you’ll pay tax on catch-up dollars now but enjoy tax-free growth and withdrawals later. If your plan doesn’t offer a Roth option, you may not be able to make catch-up contributions at all under this rule.

Regular elective deferrals (the base limits) can still be traditional or Roth, regardless of income.

Combined Contribution Limits with Employer Match

In addition to what you can contribute, your employer may also contribute via matching or profit-sharing. The IRS sets an aggregate limit on total annual additions from all sources:

  • For 2025, the combined employee + employer limit was $70,000.

  • For 2026, it increases to $72,000 (not counting age catch-up amounts).

Catch-up contributions for age 50+ typically do not count against this total limitation, meaning more room for tax-advantaged savings if you qualify.
