What Are 401(k) Contribution Limits?
The IRS sets an annual contribution limit for 401(k) plans, determining how much you and your employer can contribute each year to the retirement savings plan. These limits are reviewed annually and adjusted to account for inflation and cost-of-living changes, which is why the numbers shift from year to year.
The IRS also has compensation limits to ensure fairness, so that those earning higher incomes don’t benefit more than those with modest salaries.
401(k) Contribution Limits for 2026
The 401(k) contribution limits for 2026 are:
- Employee contributions: $24,500
- Combined employee and employer contributions: $72,000
Depending on the plan, you may also be able to make extra post-tax contributions. However, your total contributions cannot be more than your annual salary at the company where you have your 401(k) plan.
Roth 401(k) Contribution Limits for 2026
The contribution limit for Roth 401(k) accounts is the same as that of a traditional 401(k) account: $24,500 for employee contributions and $72,000 for combined employer and employee contributions.
The same contribution limits also apply to the federal government’s Thrift Savings Plan, which has most 457 plans and 403(b) plans.
Don't Exceed the Combined Limit
If you have both a traditional and a Roth 401(k), your total contributions across both accounts cannot exceed $24,500 in 2026. Going over this limit can result in double taxation on the excess amount.
Changes to 401(k) Contribution Limits in 2026
The IRS has steadily increased 401(k) contribution limits over the years to keep pace with inflation. Here's how the limits have changed in recent years.
| Contribution Type | 2024 | 2025 | 2026 |
|---|---|---|---|
| Employee contributions | $23,000 | $23,500 | $24,500 |
| Combined employee + employer | $69,000 | $70,000 | $72,000 |
| Catch-up (age 50–59 and 64+) | $7,500 | $7,500 | $8,000 |
| Higher catch-up (ages 60–63) | N/A | $11,250 | $11,250 |
| IRA limit | $7,000 | $7,000 | $7,500 |
Catch-up Contributions for 401(k) Plans
Catch-up contributions allow those aged 50 or older to make extra contributions to their 401(k) and individual retirement accounts (IRA). This means that apart from the annual contribution limit set by the IRS, you can contribute an additional amount to your retirement plan.
A catch-up contribution can be a helpful strategy for financial stability during retirement. If you haven't been able to max out your 401(k) during your working life, catch-up contributions let you save more and benefit from additional tax advantages in the years approaching retirement.
401(k) Contribution Limits for Individuals Over 50 in 2026
If you're 50 or older in 2026, you can contribute an additional $8,000 to your 401(k) as a catch-up contribution, bringing your total employee contribution to $32,500.
If you're between ages 60 and 63, you qualify for a higher catch-up contribution of $11,250 instead of $8,000, bringing your total to $35,750 if your plan allows.
Roth 401(k) Contribution Limits for Individuals Over 50 in 2026
The catch-up contribution limit for Roth 401(k) accounts matches the traditional 401(k) at $8,000 in 2026 for those aged 50 and older. If you have both a traditional and a Roth 401(k), your catch-up contributions across both accounts cannot exceed $8,000 total.
Did You Know?
Starting in 2026, high earners who made more than $150,000 in FICA wages the prior year are required to make catch-up contributions as Roth contributions. This is a new SECURE 2.0 rule that affects how some employees over 50 save for retirement.
Multiple 401(k) Plans: What You Need To Know
If you have multiple 401(k) plans with different employers, your total employee contributions across all plans cannot exceed $24,500 in 2026. However, employer contributions are counted separately and may allow your total retirement savings to exceed that cap.
If you participate in plans at two unrelated employers, each employer can contribute separately up to the combined limit. This means your total retirement savings across both plans could be higher than the individual employee cap alone.
After-Tax 401(k) Contribution Limits for 2026
If you’ve already contributed up to the maximum limit to your 401(k) as an employee, you may be able to save more through after-tax contributions. While this allows you to increase your retirement savings, keep in mind that you may owe taxes again when you withdraw the funds, depending on how they are rolled over.
Not all plans allow after-tax contributions, so check with your employer. If your plan offers this option, the total combined limit for employee deferrals, employer contributions, and after-tax contributions is $72,000 in 2026.
Watch Out for Taxes on Withdrawal
After-tax contributions grow in your 401(k) tax-deferred, but earnings may be taxed when withdrawn depending on how the funds are rolled over. Consult a financial advisor before making after-tax contributions.
401(k) Limits for Highly Paid Employees
Those who earn high salaries are categorized as Highly Compensated Employees (HCE) and are subject to stricter contribution limits.
The IRS uses the Actual Deferral Percentage (ADP) test to prevent highly paid employees from receiving unfair tax advantages from 401(k) plans. In 2026, a highly compensated employee is defined as someone who earned more than $160,000.
Highly compensated employees may face restrictions on how much they can contribute to their 401(k)s. The IRS limits the income on which an employer can offer a contribution match to $360,000 in 2026. Regardless of your income, the maximum amount you can contribute from all sources cannot exceed $72,000 in 2026.
If you're a highly compensated employee, consulting a tax or financial professional can help you understand exactly how these limits apply to your situation and how to maximize your contributions within the rules.
What Happens When You Make Excess Contributions?
Excess contributions are taxed twice — once when contributed and again when distributed.
If you contribute more than the annual limit, the excess must be removed by April 15 of the following year to avoid double taxation. You must also report excess contributions on Form 1099-R when you file taxes.
In most cases, 401(k) plans have safeguards to prevent excess contributions. However, you may accidentally contribute too much if you have multiple plans or change jobs mid-year.
Maximize Your 401(k) Savings in 2026
Maximizing your retirement contributions is one of the smartest financial moves you can make. Take advantage of employer matching, avoid 401(k) loans or early withdrawals, and contribute as much as you can each year to make the most of your retirement savings.
But if high-interest debt is eating into what you could be saving, it may be worth addressing both at the same time. As a trusted debt relief company, TurboDebt® can help you find a path to reduce what you owe so more of your income can go toward building your retirement.
