Every autumn the IRS tweaks the dials, and the 401k contribution limits 2026 edition is no exception — the amount you can defer from your paycheck ticked up again. That sounds simple, but three separate limits hide inside your plan, and most people know only one. Here is the plain-language version of what you can save, who gets the bonus tiers, and where the fine print bites.
What changed in 2026
Contribution limits move with inflation, so 2026 continues the recent pattern of small annual bumps.
- The employee deferral limit rose. For 2026 you can contribute roughly $24,000 of your own salary, a modest step up from 2025. Treat that as directional and confirm the official number on IRS.gov.
- The super catch-up is now normal. The SECURE 2.0 enhanced catch-up for ages 60 to 63 is fully in effect, letting that narrow band contribute meaningfully more than the standard 50+ catch-up.
- Roth 401k space keeps growing. More plans default new hires into a Roth 401k. The dollar limit matches a Traditional 401k — the difference is when you pay tax, not how much you can add.
- The combined plan cap adjusted too. The total of your money plus employer money climbed, which matters most for high earners doing after-tax mega-backdoor contributions.
The 2026 numbers at a glance
Use this as a map, not gospel. The IRS publishes exact figures each fall, and plan rules can be stricter than the legal maximum.
| Limit |
Who it applies to |
2026 (approximate) |
| Employee salary deferral |
Everyone |
~$24,000 |
| Standard catch-up |
Age 50 and older |
+~$8,000 |
| Super catch-up |
Ages 60–63 only |
+~$11,250 instead of standard |
| Total plan cap (you + employer) |
Everyone |
~$72,000 |
| Compensation cap counted |
High earners |
~$360,000+ |
The deferral limit and the total plan cap are two different ceilings. Your own contributions stop at the deferral limit; employer match and after-tax dollars keep filling the account up to the larger total cap.
Catch-up contributions: the age tiers that matter
Catch-up rules reward you for turning 50, then reward one four-year window even more.
- Under 50: you get the base deferral limit and nothing extra.
- 50 to 59: add the standard catch-up on top of the base limit.
- 60 to 63: you qualify for the enhanced super catch-up — the single biggest window to shovel money in before retirement.
- 64 and up: you drop back to the standard 50+ catch-up. The super amount is a four-year perk only.
One honest caveat: SECURE 2.0 requires high earners (above an inflation-adjusted wage threshold) to make catch-up contributions as Roth rather than pre-tax. If your plan lacks a Roth option and you are over that income line, you may lose the catch-up until the plan updates. Ask your plan administrator directly.
The limit most people forget
The salary-deferral number gets all the attention, but the total plan cap — sometimes called the 415(c) limit — is what lets aggressive savers go further. It counts your deferrals, the employer match, and any after-tax (non-Roth) contributions your plan allows.
If your plan supports after-tax contributions and in-plan Roth conversions, you can fill the gap between your deferral limit and the total cap with the "mega-backdoor Roth." It is powerful but plan-dependent — many plans do not offer the after-tax bucket, so do not assume yours does.
How to hit the limit without wrecking cash flow
- Contribute by percentage, not a flat dollar amount, so raises automatically lift your savings.
- Do not front-load blindly. If your employer matches per paycheck and you max out in September, you can forfeit the match for the rest of the year unless the plan has a "true-up." Check whether yours does.
- Split Roth and Traditional if you are unsure about future tax rates — a hedge, not a hesitation.
- Reset your percentage every January, because the limit changes yearly and last year's setting may leave money behind.
What to skip
- Skip maxing the 401k before capturing free match. Match first, then push toward the full limit.
- Skip assuming the headline number is final. The figures here are approximate; verify the 2026 amounts against the IRS before adjusting payroll.
- Skip high-fee funds just to hit the cap. Contribution room is worthless if a 1% expense ratio quietly eats decades of growth.
FAQ
How much can I contribute to my 401k in 2026?
Roughly $24,000 of your own salary if you are under 50, plus catch-up amounts if you are older. Confirm the exact 2026 figure on IRS.gov, since plans can set lower internal caps.
Do employer contributions count toward my limit?
Not toward your personal deferral limit. They count toward the separate, larger total plan cap of around $72,000 for 2026.
Is the Roth 401k limit different from the Traditional?
No. They share the same deferral limit. The only difference is tax timing — Roth is after-tax now, Traditional is pre-tax now.
What is the super catch-up and do I qualify?
It is an enhanced catch-up for people aged 60 to 63, letting that age band contribute more than the standard 50+ catch-up. Outside that window, you get the regular catch-up.
