401(k) Contribution Limits 2026: Everything You Need to Know

Maxing out your 401(k) is one of the highest-leverage financial moves available to American workers. Tax-deferred (or tax-free) growth, potential employer match, and decades of compounding make the 401(k) the foundation of most retirement plans. Here is a complete breakdown of every 2026 limit you need to know.

Use our Paycheck Calculator to see exactly how increasing your 401(k) contribution affects your net take-home pay.

Employee Contribution Limit: $23,500

The core employee elective deferral limit remains at $23,500 in 2026. This is the amount you can defer from your salary — before taxes for traditional contributions, after taxes for Roth contributions.

To max out on a biweekly payroll (26 pay periods), you would contribute approximately $904 per paycheck. On a semi-monthly schedule (24 periods), that is $979 per paycheck.

Catch-Up Contributions: Age 50 and Older

Once you turn 50, you can contribute an additional $7,500 per year, bringing your personal maximum to $31,000.

The SECURE 2.0 “Super Catch-Up” for Ages 60–63

A major change from the SECURE 2.0 Act: employees aged 60, 61, 62, or 63 qualify for a higher catch-up contribution of $11,250 in 2026, instead of the standard $7,500. This peaks at the age range right before traditional retirement, allowing a final acceleration of savings.

Age Range	Standard Limit	Catch-Up	Total Personal Max
Under 50	$23,500	$0	$23,500
50–59	$23,500	$7,500	$31,000
60–63	$23,500	$11,250	$34,750
64+	$23,500	$7,500	$31,000

Total Plan Limit: $70,000

The Section 415 limit caps all contributions to a single participant’s 401(k) at $70,000 in 2026. This includes:

• Your employee deferrals (up to $23,500)
• Employer matching contributions
• Employer profit-sharing contributions
• After-tax (non-Roth) voluntary contributions

High earners whose employers make large profit-sharing contributions should track this ceiling. With catch-up contributions, the ceiling rises to $77,500.

Roth 401(k): Same Limits, Different Tax Treatment

The Roth 401(k) shares the exact same contribution limits as the traditional 401(k). The difference is timing of the tax benefit:

• Traditional 401(k): Contributions reduce your taxable income today. Withdrawals in retirement are taxed as ordinary income.
• Roth 401(k): Contributions are made with after-tax dollars. All qualified withdrawals in retirement are completely tax-free.

Beginning in 2026, the SECURE 2.0 Act also eliminates required minimum distributions (RMDs) from Roth 401(k)s during the account owner’s lifetime, making them more attractive for estate planning.

Which Should You Choose?

• Choose Roth if you expect to be in a higher tax bracket in retirement, or if you are early in your career with a lower current income.
• Choose Traditional if you are in a high tax bracket now and expect lower income in retirement.
• When in doubt, split contributions between both to hedge against future tax rate uncertainty.

SIMPLE IRA Limits for Small Business Employees

If your employer offers a SIMPLE IRA instead of a 401(k), the 2026 contribution limits are lower:

Limit	2026 Amount
Employee contribution	$16,500
Catch-up (age 50+)	$3,500
Total SIMPLE IRA max	$20,000

SIMPLE IRA plans are common at small businesses. If your employer offers one, you cannot contribute to a 401(k) at the same employer.

How 401(k) Contributions Reduce Your Taxes Today

Traditional 401(k) contributions reduce your federal taxable income dollar for dollar. For a single filer in the 22% bracket contributing the full $23,500:

• Tax savings: $23,500 × 22% = $5,170 per year
• After-tax cost of maxing out: $23,500 − $5,170 = $18,330

State tax savings depend on your state. Nine states have no income tax. See our Paycheck Calculator to model the exact net pay impact in your state.

Employer Match: Free Money First

Before worrying about whether to choose Roth or traditional, prioritize capturing your full employer match. A 50% match on up to 6% of salary is a guaranteed 50% return on investment — no market can reliably beat that.

If your salary is $75,000 and your employer matches 50% of the first 6% ($4,500), you get $2,250 in free contributions. Leaving that on the table is the single most costly retirement mistake you can make.

Contribution Strategy for 2026

1. Contribute enough to get the full employer match (free money)
2. Max your HSA if you have a high-deductible health plan ($4,300 individual / $8,550 family in 2026) — it is triple tax-advantaged
3. Max your Roth IRA ($7,000 / $8,000 age 50+) if income permits
4. Return to 401(k) and contribute up to the $23,500 limit
