Over 50? The 2026 401(k) Catch-Up Rules Have Three Different Paths

1. The basic 2026 employee limit is $24,500

For 2026, the employee elective-deferral limit for most 401(k), 403(b), governmental 457 plans and the federal Thrift Savings Plan is $24,500.¹

Catch-up contributions sit on top of that limit when the participant and the plan qualify.

2. Age 50 through 59: the general catch-up is $8,000

If you are age 50 or older by the end of the calendar year and your plan permits catch-up contributions, the general 2026 catch-up limit is $8,000.²

That means someone eligible for the standard catch-up could potentially make employee deferrals of:

Your plan terms and compensation can still limit what you are able to contribute.

3. Ages 60 through 63: the catch-up is higher

SECURE 2.0 created an enhanced catch-up for workers who turn 60, 61, 62 or 63 during the calendar year. For 2026, that catch-up is $11,250, rather than $8,000.²

The age window is specific. It does not mean “60 and older forever.” Once a participant is outside the 60–63 age band, the general age-50 catch-up amount applies again unless future law changes the structure.

4. Age 64 and older: back to the general $8,000 catch-up

For 2026, a participant age 64 or older generally returns to the $8,000 catch-up limit for most 401(k)-type plans, assuming the plan permits catch-ups.

5. Then comes the Roth catch-up rule for some higher-paid workers

The second question is how the catch-up must be taxed.

IRS participant guidance says that beginning in 2026, participants in plans with Roth features that offer catch-up contributions must make their catch-up contributions on a Roth basis if their prior-year wages from the plan sponsor exceeded $150,000 for the 2026 determination.²

That is easy to confuse with several other numbers. The $150,000 test is not the same thing as your household taxable income, modified AGI, or the 401(k) highly compensated employee threshold.

6. “Roth catch-up” does not mean your entire 401(k) contribution must be Roth

For a participant subject to the Roth catch-up requirement, the rule applies to the catch-up portion. It does not automatically mean every dollar of the regular $24,500 deferral must be Roth.

Your plan’s options and payroll implementation matter. If you are close to the regular limit late in the year, verify how the plan will classify and route contributions after you cross into catch-up territory.

7. This is different from the 401(k) total annual-additions limit

Another common source of confusion is that the employee deferral limit is not the same as the plan’s total annual-additions limit. Employer matching, profit-sharing and certain after-tax contributions can use a separate, larger limit.

That is the question covered in Terra’s existing Money Now guide: Think you’ve maxed out your 401(k)? Maybe not.

This article is narrower: it explains who gets which catch-up amount and when the catch-up may have to be Roth.

8. A simple 2026 decision path

Then confirm that your specific plan allows catch-up contributions and how payroll handles them.

9. What about IRAs and SIMPLE plans?

They have different limits. For 2026, the IRA catch-up for someone age 50 or older is $1,100. SIMPLE plans also have their own regular and age-based catch-up amounts.²

Do not copy the $8,000 or $11,250 401(k)-type numbers into an IRA or SIMPLE plan.

10. What should you check before increasing payroll deductions?

• Your age on December 31, 2026.
• Whether your employer plan permits catch-up contributions.
• Your 2025 wages from the employer sponsoring the plan if you may be subject to the Roth catch-up rule.
• Whether the plan has the Roth feature needed to administer the rule.
• Whether raising the contribution rate too early could affect how your employer match is calculated if the plan does not provide a true-up.
• Your cash-flow needs and other savings priorities.
