2026 401(k) Contribution Limits Explained
The IRS has officially released the new cost-of-living adjustments for retirement accounts in 2026. Thanks to recent inflation data, the limits have bumped up again. Here is exactly how much you can contribute this year.
1. The 2026 Standard 401(k) Limit: $24,500
For the tax year 2026, the maximum amount an employee can contribute to their 401(k), 403(b), or most 457 plans out of their own paycheck is $24,500.
This is a $500 increase from 2025. If you want to max out your 401(k) this year and you get paid bi-weekly (26 paychecks), you need to contribute $942.30 per paycheck.
You can choose to make these contributions as traditional pre-tax (lowering your taxable income this year) or Roth (paying taxes now so the money grows tax-free forever). You can also split it between the two, but the combined total of your pre-tax and Roth contributions cannot exceed the $24,500 limit.
2. Historical Context: How Limits Have Grown
The IRS adjusts these limits based on inflation (specifically, the Consumer Price Index for All Urban Consumers, or CPI-U). Because inflation was relatively high in the mid-2020s, the limits have jumped aggressively in recent years. Here is how the standard employee limit has grown:
| Tax Year | Standard Limit | Catch-Up (Age 50+) |
|---|---|---|
| 2022 | $20,500 | $6,500 |
| 2023 | $22,500 | $7,500 |
| 2024 | $23,000 | $7,500 |
| 2025 | $24,000 | $7,500 |
| 2026 | $24,500 | $7,500 |
3. Catch-Up Contributions (Age 50+)
If you are aged 50 or older at any point during 2026, the IRS allows you to make an additional "catch-up" contribution so you can stash away more money before retirement.
For 2026, the standard catch-up contribution limit remains at $7,500. This means if you are 50+, your total maximum employee contribution for the year is $32,000 ($24,500 standard + $7,500 catch-up).
The SECURE 2.0 Act "Super Catch-Up" (Ages 60-63)
Starting in 2025 and continuing into 2026, a special rule from the SECURE 2.0 Act applies to people aged 60, 61, 62, and 63. If you fall in this exact age bracket, your catch-up limit is bumped to $11,250 (or 150% of the standard catch-up limit).
4. The Employer Match & Safe Harbor Plans
We mentioned earlier that employer matches do not count against your personal $24,500 limit. But how exactly do matches work?
Many companies use a formula like "100% match on the first 3%, and 50% match on the next 2%." This is often designed around IRS "Safe Harbor" requirements, which allow companies to avoid complex non-discrimination testing as long as they provide a baseline match to all employees.
If you make $100,000 a year and your employer matches up to 5%, that is a free $5,000. You could contribute $24,500, they contribute $5,000, and a total of $29,500 goes into your account. Always contribute at least enough to get the full match—it is literally free money and a guaranteed 100% return on your investment.
5. The Absolute Maximum Limit: $71,000
There is also an absolute maximum limit (the Section 415 limit) on how much money can go into a 401(k) from all sources combined.
For 2026, this total combined limit has been raised to $71,000 (or $78,500 if you are 50+). This massive bucket is filled by three different sources:
The $71,000 Absolute Limit Breakdown
The $71,000 total limit is the sum of your personal contributions, your employer's match, and any special after-tax contributions.
How do you reach $71,000? (The Mega Backdoor Roth)
Unless your employer is incredibly generous and matching $46,500 a year, you won't hit the $71,000 limit with just the standard $24,500 and a match.
High-income earners reach this limit using the "Mega Backdoor Roth" strategy. If your 401(k) plan allows it, you can make after-tax, non-Roth contributions above and beyond the $24,500 limit, up until the entire bucket hits $71,000. You then immediately roll those after-tax contributions into a Roth IRA or in-plan Roth 401(k), allowing that massive sum of money to grow completely tax-free forever. Not all employers offer this feature, so you must check your specific plan document.
6. What About IRAs?
The 401(k) limit does not impact your IRA limits! They are completely separate buckets, meaning you can max out both.
For 2026, the contribution limit for Individual Retirement Accounts (both Roth and Traditional IRAs) is $7,500. If you are 50 or older, you can add an extra $1,000, bringing your total IRA limit to $8,500.

Frequently Asked Questions
What happens if I overcontribute to my 401(k)?
If you accidentally contribute more than $24,500 (which often happens if you switch jobs mid-year and your new employer doesn't know what you contributed at your old job), you must contact your HR department or plan administrator immediately. They will issue a "corrective distribution" to return the excess funds to you. You must do this before tax day, or you will be taxed on that money twice!
I can't afford to max it out. What should I do?
Maxing out a 401(k) is difficult for the average earner. Do not feel discouraged if you cannot hit $24,500. A highly effective, human strategy is to increase your contribution rate by 1% every six months. Or, whenever you get a 3% raise at work, allocate 2% to your 401(k) and keep 1% in your paycheck. You will slowly inch your way up without ever feeling a cut to your standard of living.
