There is no maximum age for contributing to a 401(k). You can keep contributing at 70, 73 or 80 as long as you are still working for the employer that sponsors the plan and your plan allows it.
What does change with age are the rules around it: a possible minimum age of 21 to join, higher “catch-up” limits from age 50, an even higher limit at ages 60 to 63, and required withdrawals that can begin at 73. This guide explains each rule, with the 2026 numbers.
Limits and rules are accurate as of October 10, 2026, based on IRS and public sources. Plans can be more restrictive than the law, so check your plan documents. This is general information, not financial or tax advice.
Is There an Age Limit for 401k Contributions?
No. Federal law sets no upper age limit on 401(k) contributions. What you need is earned income from the employer that sponsors the plan, and a plan that still allows you to defer salary.
If you retire or stop receiving pay from that employer, you generally cannot keep contributing to that plan. The limit comes from your work status, not your birthday.
What Is the Minimum Age for a 401k?
The highest minimum age a plan can require is 21. Many plans set no minimum age at all, and some let younger workers join right away.
Plans can also require up to one year of service before you can make your own salary deferrals. So a 19-year-old at a company with a 21-and-one-year rule would have to wait, while a 19-year-old at a plan with no age rule could start sooner.
Part-Time Workers
Under current rules, a long-term part-time employee who works at least 500 hours in each of two consecutive 12-month periods must be allowed to make their own deferrals, even if the plan’s normal rules would exclude them. Ask your plan administrator how your plan counts service.
Can You Contribute to a 401k After Age 70?
Yes. If you are still working and receiving pay from the plan sponsor, you can keep contributing to a traditional or Roth 401(k) after age 70, 73 or any later age. Your contributions cannot exceed your compensation from that employer.
Two practical conditions apply:
- Your plan must still be open to you. Some plans have their own rules, so check with HR.
- You must have earned pay. Pension, Social Security or investment income does not count as compensation for 401(k) deferrals.
Contributing After 73 and Required Minimum Distributions
Required minimum distributions (RMDs) generally begin at age 73, and the starting age is scheduled to rise to 75 in 2033. Contributing and taking RMDs are separate things.
If you are still working and own less than 5% of the company, you can usually delay RMDs from that employer’s current 401(k) until you retire. This exception does not cover old 401(k)s from previous employers or IRAs. Plan terms can differ, so confirm with your plan. A plan may require distributions to start by April 1 of the year after you reach 73 in some cases.
Roth 401(k) accounts no longer require lifetime RMDs, starting in 2024.
What If You Are Retired?
Retired people generally cannot contribute to a former employer’s 401(k) because they no longer earn compensation from that company. If you return to part-time work for an employer with a plan, you may be able to contribute again, subject to the plan’s rules.
Solo 401(k) After 70
Self-employed people with a solo 401(k) can also keep contributing at older ages as long as they have self-employment income. RMD rules apply based on ownership and plan type, so check with a tax professional if you own 5% or more of the business.
401k Contribution Limits 2026 by Age
The IRS sets limits each year. For 2026, these are the main numbers:
| Your age (at end of 2026) | Salary deferral limit | Catch-up | Your total (employee) | Combined employee + employer limit |
|---|---|---|---|---|
| Under 50 | $24,500 | None | $24,500 | $72,000 |
| 50 to 59 | $24,500 | $8,000 | $32,500 | $80,000 |
| 60 to 63 | $24,500 | $11,250 | $35,750 | $83,250 |
| 64 and older | $24,500 | $8,000 | $32,500 | $80,000 |
The ages 60 to 63 limit is optional for plans, so your plan must allow it. Employer matching and profit-sharing contributions count toward the combined limit, not the $24,500 employee limit.
Pay that can be counted toward plan contributions is capped at $360,000 in 2026.
Catch-Up Contributions Depend on Your Age at Year-End
You qualify for catch-up contributions if you are 50 or older by the end of the calendar year. You do not need to have had your birthday yet. Someone who turns 50 on December 20 can make catch-up contributions for the whole year.
The same year-end test applies to the 60 to 63 limit. A worker who is 59 in January and turns 60 later in the year qualifies for the higher limit that year.
The Roth Catch-Up Rule for Higher Earners
Starting in 2026, if your Social Security (FICA) wages from your employer were more than $150,000 in 2025, any catch-up contributions you make must go in as Roth (after-tax) contributions. Your regular $24,500 deferral can still be pre-tax.
The test looks at your wages from that employer, not your household income. If your plan does not offer a Roth option, ask your administrator how catch-up contributions work for you.
Limits Apply Across All Your 401(k) Plans
The $24,500 employee limit applies to you personally, not per employer. If you change jobs mid-year and contribute to two plans, your combined deferrals across both cannot exceed the limit.
What Are the 2027 401k Contribution Limits?
The IRS has not yet announced the 2027 limits. It typically releases them in late October or mid-November, after September inflation data comes out.
Industry forecasts, which are estimates and not official, point to an increase in the employee deferral limit to somewhere around $25,000 to $25,500. Until the IRS publishes its notice, plan around the 2026 figures above.
Is There an Income Limit for Roth 401k Contributions?
No. A Roth 401(k) has no income limit. High earners can contribute as long as their employer’s plan offers a Roth option. The same $24,500 limit applies across your traditional and Roth 401(k) deferrals combined.
A Roth IRA is different. It has income limits, and for 2026 the phase-out for single filers begins at $153,000 and ends at $168,000 of modified adjusted gross income.
Age Milestones for a 401k
| Age | What changes |
|---|---|
| Up to 21 | A plan can require you to be 21 before you join |
| 50 | Catch-up contributions become available |
| 55 | The “rule of 55” may allow penalty-free withdrawals if you leave your employer in or after the year you turn 55, if your plan allows |
| 59½ | Withdrawals no longer face the 10% early withdrawal penalty, though regular income tax applies to traditional accounts |
| 60 to 63 | Higher catch-up limit of $11,250 in 2026, if your plan allows |
| 64 and older | Back to the standard $8,000 catch-up |
| 73 | RMDs generally begin, with the still-working exception for under-5% owners |
What Happens If You Contribute Too Much?
If your deferrals go over the annual limit, you can generally withdraw the excess by April 15 of the following year to avoid double taxation. This is most common when someone has two 401(k)s in the same year. Contact your plan administrator or a tax professional as soon as you notice it.
Frequently Asked Questions
Is there an age limit for 401k contributions?
No. There is no maximum age for contributing to a 401(k). You can keep contributing at any age as long as you are still earning pay from the employer that sponsors the plan and your plan allows it. Required minimum distributions can start at 73, but working owners of less than 5% can usually delay them.
What is the minimum age to contribute to a 401k?
A plan cannot require an age above 21. Some plans have no minimum age. A plan can also require up to one year of service before you can make your own contributions, so the practical rules depend on your employer’s plan.
Can I contribute to a 401k at 70 or 73?
Yes, if you are still working for the plan sponsor and receiving pay. You can contribute to a traditional or Roth 401(k) after 70 and after 73. If you own less than 5% of the company, you can generally delay RMDs from that employer’s plan until you stop working there.
How much can a 59-year-old contribute to a 401k in 2026?
A 59-year-old can contribute up to $32,500 in 2026, which is the $24,500 standard limit plus the $8,000 catch-up. If they turn 60 by December 31, 2026 and their plan allows it, the limit is $35,750 instead.
How much can a 61-year-old contribute to a 401k in 2026?
A 61-year-old can contribute up to $35,750 in 2026, made up of the $24,500 standard limit plus an $11,250 catch-up, if the plan allows the higher catch-up. If it does not, the limit is $32,500.
What happens to my 401k contributions after I turn 64?
Nothing stops. At 64 you go back to the standard catch-up of $8,000, so your 2026 limit is $32,500. The higher $11,250 catch-up applies only for ages 60, 61, 62 and 63.
Do I have to take RMDs if I keep working past 73?
Not always. If you are still working for the employer that sponsors the plan and own less than 5% of it, you can usually delay RMDs from that plan until you retire. RMDs from IRAs and from old employers’ plans are generally not delayed. Roth 401(k) accounts no longer have lifetime RMDs.
Is there an age limit for Roth 401k contributions?
No. The Roth 401(k) has no maximum age and no income limit. You need a plan that offers a Roth option and earned income from that employer. The $24,500 employee limit applies to your traditional and Roth deferrals combined.
Is there an age limit for 401k catch-up contributions?
Catch-up contributions start at age 50, based on your age at the end of the calendar year. There is no upper age limit for the standard catch-up, though the higher $11,250 limit applies only at ages 60 to 63. Higher earners must make catch-ups as Roth contributions.
