The 401(k) contribution limits for 2026 let you defer up to $24,500 from your paycheck, with workers 50 and older adding catch-up contributions that raise the personal ceiling to $32,500, or $35,750 if you are between 60 and 63. Counting employer matching and other sources, total deposits into the account can reach $72,000 for the year, or more once catch-ups are added on top.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Whether you can actually hit those numbers depends on your age, your income, and a few plan rules worth knowing before you set your deferral rate.
The Employee Deferral Limit
The most you can contribute from your own salary in 2026 is $24,500, up from $23,500 in 2025.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 That cap covers traditional pre-tax and Roth 401(k) contributions combined. You can split them however you prefer, as long as the total across both types stays at or below $24,500.2Internal Revenue Service. Roth Comparison Chart
The limit follows you as an individual, not your employer. If you work two jobs and contribute to separate 401(k) plans, your combined deferrals across both plans still share one $24,500 ceiling.3Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits
Catch-Up Contributions at 50 and Older
If you turn 50 or older by December 31, 2026, you qualify for an additional $8,000 in catch-up contributions on top of the standard limit, bringing your personal maximum to $32,500.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 No special application is required. Let your payroll department know you want to exceed the standard deferral once you clear the age threshold.
SECURE 2.0 introduced an enhanced catch-up window for participants aged 60 through 63. During that narrow age range in 2026, your catch-up allowance jumps to $11,250 instead of $8,000, pushing your personal ceiling to $35,750.1Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 That is the highest individual contribution available to any 401(k) participant. The enhanced amount reverts to the standard catch-up once you turn 64.
The Roth Catch-Up Rule for Higher Earners
A new rule took effect in 2026. If your prior-year FICA wages from your employer exceeded a threshold (set at $145,000 in the statute and indexed for inflation), your catch-up contributions must go in as after-tax Roth dollars rather than pre-tax.4Internal Revenue Service. Treasury, IRS Issue Final Regulations on New Roth Catch-Up Rule, Other SECURE 2.0 Act Provisions The threshold is based on wages subject to Social Security tax (Box 3 on your W-2), not your total compensation.
The rule applies only to catch-up contributions. Your regular $24,500 in deferrals can still be pre-tax or Roth at your discretion. If you earned less than the threshold, you can continue choosing between pre-tax and Roth catch-up contributions as before, assuming your plan offers both options.
The IRS final regulations formally take full effect for 2027, so plans are expected to make a reasonable good-faith compliance effort during 2026.4Internal Revenue Service. Treasury, IRS Issue Final Regulations on New Roth Catch-Up Rule, Other SECURE 2.0 Act Provisions If your plan does not yet offer a Roth option at all, the IRS has indicated catch-up contributions can continue on a pre-tax basis during the transition. Ask your plan administrator how your employer is handling the change.
Total Limit Including Employer Contributions
Beyond what you contribute from your paycheck, federal law caps the total flowing into your 401(k) from all sources at $72,000 for 2026, or 100% of your compensation if that is less.5Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living (Notice 2025-67) “All sources” includes your deferrals, employer matching, profit-sharing contributions, and any voluntary after-tax contributions your plan may allow.
Catch-up contributions do not count against the $72,000 ceiling.6Internal Revenue Service. Fixing Common Plan Mistakes – Failure to Limit Contributions for a Participant So the true maximum that can flow into a 401(k) in 2026 depends on your age:
- Under 50: $72,000
- Age 50 through 59, or 64 and older: $80,000 ($72,000 plus $8,000 catch-up)
- Age 60 through 63: $83,250 ($72,000 plus $11,250 enhanced catch-up)
Most people will not reach $72,000 through deferrals and matching alone. Some plans allow voluntary after-tax contributions (separate from Roth deferrals) that fill the gap between your deferrals plus employer contributions and the $72,000 cap. If your plan permits those after-tax contributions and also allows in-plan Roth conversions, you can execute what is commonly called a “mega backdoor Roth,” funneling significantly more money into Roth savings each year. Not every plan offers this feature.
Unlike the deferral limit, the $72,000 total cap applies separately for each unrelated employer. Hold two jobs with generous matching and each employer’s plan has its own $72,000 ceiling.3Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits
When Highly Compensated Employees Get Capped Early
Even if you have the cash flow to max out, nondiscrimination testing can cut your contributions short. Traditional 401(k) plans must run annual tests confirming that higher-paid employees are not saving at dramatically higher rates than everyone else. These are the Actual Deferral Percentage and Actual Contribution Percentage tests.7Internal Revenue Service. 401(k) Plan Fix-It Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests
You are classified as a highly compensated employee if you owned more than 5% of the business at any point during the current or prior year, or if your prior-year compensation exceeded $160,000.5Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, as Adjusted for Changes in Cost-of-Living (Notice 2025-67) When lower-paid employees do not contribute enough to the plan, the test fails. The fix usually means returning excess deferrals to the highly compensated employees as taxable income, even when those contributions were well below the IRS maximum.7Internal Revenue Service. 401(k) Plan Fix-It Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests
Some employers avoid this problem by adopting a safe harbor 401(k) design, which satisfies nondiscrimination rules automatically in exchange for mandatory employer contributions like matching or a flat percentage for all participants.7Internal Revenue Service. 401(k) Plan Fix-It Guide – The Plan Failed the 401(k) ADP and ACP Nondiscrimination Tests If your employer uses a safe harbor plan, these testing restrictions do not apply to you.
Two Jobs and Excess Contributions
When you contribute to 401(k) plans at two or more unrelated employers in the same year, neither employer sees the other’s deferrals. Your combined contributions across all plans still cannot exceed $24,500 (or $32,500 and $35,750 with catch-up), and tracking compliance is your responsibility.3Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits A single employer’s payroll system will typically stop deferrals once you hit the limit. That safeguard disappears when two separate employers are involved.
If your total deferrals exceed the legal limit, notify one of your plans and withdraw the excess by April 15 of the following year. Filing an extension on your tax return does not push back the deadline.8Internal Revenue Service. Consequences to a Participant Who Makes Excess Deferrals to a 401(k) Plan Meet the deadline and the withdrawn excess itself is not taxed again, because it was already included in your income for the contribution year. You will owe tax only on investment earnings the excess generated while in the account, and the withdrawal will not trigger the 10% early distribution penalty.9Internal Revenue Service. Retirement Topics – What Happens When an Employee Has Elective Deferrals in Excess of the Limits
Miss the deadline and the money gets taxed twice: once in the year you contributed it, and again when it is eventually distributed from the plan.8Internal Revenue Service. Consequences to a Participant Who Makes Excess Deferrals to a 401(k) Plan There is no mechanism to fix this after April 15.
Pacing Contributions Across the Year
To reach the maximum, divide your annual target by the number of pay periods and set that per-paycheck amount through your benefits portal, as either a fixed dollar figure or a percentage of gross pay. Timing matters more than people realize. If you set your contribution rate too high and hit the annual cap before December, payroll stops withholding 401(k) deferrals for the remaining pay periods. That creates a gap where you earn a paycheck but make no contributions, and you can miss out on employer matching for those periods.
Some employers offer a “true-up” provision that reconciles your full-year match after the year ends; many do not. If your employer matches per pay period and does not true up, spreading your contributions evenly across all paychecks is the safer approach. Checking your most recent pay stub against the annual target each quarter catches drift before it turns into a December scramble.
