401(k) Contribution Limits for 2026: Employee, Employer, and Catch-Up

Every year the IRS adjusts how much you are allowed to contribute to a 401(k). For 2026, the limit went up — and if you are not contributing at least enough to capture your employer match, you are leaving part of your compensation on the table. Here is the complete picture for 2026.

2026 401(k) Contribution Limits at a Glance

• Employee contribution limit: $23,500
• Catch-up contribution (age 50–59 and 64+): +$7,500 — max $31,000
• Super catch-up (age 60–63): +$11,250 — max $34,750
• Total annual additions limit (employee + employer combined): $70,000
• Compensation limit (used in employer match calculations): $350,000

The 2026 employee limit of $23,500 is up from $23,000 in 2025. The catch-up limit holds at $7,500 for most eligible workers, but a SECURE 2.0 provision creates a higher "super catch-up" amount specifically for people aged 60 through 63 — a window that did not exist until 2025.

How the Employee Limit Affects Your Paycheck

Traditional 401(k) contributions come out of your paycheck before federal income tax is calculated. That reduces your taxable income dollar for dollar, which matters more than most people realize.

If you earn $80,000 and contribute the full $23,500, your federal taxable income drops to $56,500. At the 22% marginal bracket, that saves roughly $5,170 in federal income tax alone — plus whatever your state charges. Every dollar you put in pre-tax costs you less than a dollar out of pocket.

Here is what different contribution levels do to a biweekly paycheck for an $80,000-a-year single filer:

• $0 contributed: No reduction. Full federal and FICA taxes apply to every dollar.
• $6,000/year (~7.5%): Gross paycheck drops about $231 per period, but the net hit after federal tax savings is roughly $180.
• $12,000/year (15%): About $462 less gross per paycheck, roughly $360 net after tax savings.
• $23,500/year (max): About $904 less gross per paycheck, roughly $705 net after federal tax savings.

The actual cost to your take-home is always less than the contribution amount because you defer income tax on every dollar. Use the WageSplit take-home pay calculator to see how a specific contribution rate changes your paycheck based on your salary, state, and filing status.

Employer Match: The Part You Cannot Skip

The $23,500 employee limit and employer contributions are tracked separately. Employer contributions do not count against your $23,500 — the combined employee plus employer ceiling is $70,000 in 2026.

A common match structure is 100% of the first 3–6% of your salary. On an $80,000 salary with a 4% match, your employer adds $3,200 per year — but only if you contribute at least $3,200 yourself. That is a 100% immediate return on those specific dollars before any market growth.

If you are contributing below your match threshold, you are effectively declining part of your compensation. This should be the first problem to fix before worrying about anything else on this list.

Traditional vs. Roth: Same Limit, Different Tax Timing

The $23,500 limit applies to all your 401(k) contributions combined — traditional pre-tax and Roth after-tax together. You can split between the two in any proportion, but the total cannot exceed $23,500.

The tax difference is about timing. Traditional contributions reduce your taxable income now — you pay the tax later when you withdraw in retirement. Roth contributions give up the upfront deduction, but qualified withdrawals in retirement are completely tax-free. Which is better depends on whether you expect your tax rate to be higher now or in retirement. For a full comparison of how each affects your paycheck, see pre-tax vs. Roth 401(k).

Catch-Up Contributions After Age 50

Workers aged 50 and older can contribute an additional $7,500 above the base limit in 2026, for a total of $31,000. Starting in 2025, SECURE 2.0 added an enhanced limit for workers aged 60 through 63: an extra $11,250 above the base, bringing the maximum to $34,750 for that age band. At 64, you drop back to the standard $7,500 catch-up.

Catch-up contributions follow the same pre-tax or Roth rules as regular contributions. If you are 50 or older and not using catch-up room, you are skipping one of the most valuable tax-deferred savings windows available.

What Happens If You Change Jobs Mid-Year

The $23,500 limit is per person, not per employer. If you contribute to one employer's plan and then switch jobs and enroll in a new 401(k), the combined contributions across both plans still cannot exceed $23,500 for the calendar year.

Your two payroll systems will not coordinate automatically — tracking this is your responsibility. If you accidentally over-contribute, the excess must be withdrawn by April 15 of the following year. Miss that deadline and the excess gets taxed twice: once when contributed and again when withdrawn.

What to Do After You Max the 401(k)

If you hit $23,500 and want to keep saving tax-advantaged dollars, the next options in order are:

• HSA (if eligible): The 2026 self-only limit is $4,300; family coverage is $8,550. HSA contributions reduce federal income tax and FICA taxes — a better deal than a 401(k) on a per-dollar basis if you qualify.
• IRA: The 2026 IRA contribution limit is $7,000, plus $1,000 catch-up if you are 50 or older. Income limits apply for Roth IRA eligibility (phase-out starts at $150,000 for single filers in 2026).
• After-tax 401(k) with mega backdoor Roth: Some plans allow after-tax contributions up to the $70,000 total additions limit. If your plan permits in-service withdrawals or conversions, this allows additional Roth savings well above the standard limits.

The Bottom Line

For 2026: start by contributing at least enough to capture your full employer match. Then work toward the $23,500 employee limit — the federal tax savings make it cost less than the number on paper. If you are 50 or older, use the catch-up room. If you are 60 through 63, the super catch-up window is new and worth using.
