If you’re planning for retirement, you’ve likely already noticed that the IRS adjusts contribution limits each year. For 2025, the numbers are out, and they come with a surprise for older savers: a record-breaking super catch-up that could reshape how you think about maxing out your 401(k). The IRS set the 2025 elective deferral limit at $23,500, but the story gets bigger for those aged 60 to 63.

What is the maximum to contribute to a 401k in 2025?

2025 employee deferral limit

Total contribution limits for 2025

Who qualifies for catch-up contributions

  • Participants age 50 and older can add a standard catch-up of $7,500 (IRS — COLA increases for dollar limitations).
  • Employees who turn 60, 61, 62, or 63 in 2025 qualify for a super catch-up of $11,250 — that’s 150% of the regular catch-up amount (IRS — Retirement topics: Catch-up contributions).
The upshot

A participant aged 60-63 in a plan allowing the higher catch-up can defer up to $34,750 in 2025 ($23,500 + $11,250). That’s roughly 48% more than a saver under 50 can put away.

The implication: savers in their early 60s who can take advantage of the super catch-up gain a significant edge over younger workers in building retirement nest eggs.

How to max out a 401k in 2025?

Calculate your desired contribution percentage

  • Maxing out requires contributing $23,500 before year-end. Divide that by your annual salary to find the percentage. For example, a $100,000 salary needs 23.5%.

Set up automatic increases

  • Many plans allow auto-escalation. Set it to increase 1-2% each quarter until you hit the limit.

Monitor contribution limits throughout the year

  • If you change jobs or have multiple employers, ensure combined deferrals do not exceed $23,500. Coordination is essential.

What this means: Hourly or commission-based workers face a trickier math. Use a paycheck estimator to avoid under- or over-contributing.

Bottom line: Maxing out your 401(k) in 2025 means contributing $23,500 from your salary. For older workers eligible for catch-ups, the ceiling climbs to $31,000 (50+) or $34,750 (ages 60-63). Set your percentage early and check quarterly.

The pattern: consistent contributions throughout the year are more effective than last-minute lump sums for hitting the limit without cash-flow strain.

What will the 2026 401k limit be?

2026 employee deferral limit announced

  • The IRS announced on November 13, 2025, that the 2026 elective deferral limit rises to $24,500 (IRS — News release IR-2025-111).

Total limit increase for 2026

  • The total contribution limit (employee + employer) for 2026 is $72,000, up from $70,000 in 2025.

Catch-up limits for 2026

  • Standard catch-up for age 50+ remains $7,500 in 2026.
  • Super catch-up for ages 60-63 also stays at $11,250.

The pattern: The IRS increases deferral limits by about $1,000-$1,500 per year when inflation is moderate. 2026’s bump of $1,000 continues that trend.

Can older 401k savers contribute record breaking $34750 in 2025?

Details of the super catch-up provision

  • Yes. Employees aged 60-63 can defer up to $34,750 in 2025: $23,500 (standard deferral) + $11,250 (super catch-up) (IRS — Catch-up contributions).

Eligibility requirements for ages 60-63

  • You must turn 60, 61, 62, or 63 sometime in the 2025 calendar year. The super catch-up is available only to those in that four-year window.

Comparison with standard catch-up

  • The standard catch-up for age 50 and over is $7,500. The super catch-up is $11,250 — a $3,750 difference enabled by SECURE 2.0.
The catch

Not all 401(k) plans are required to offer the super catch-up provision. Check your plan document or ask your benefits administrator before banking on that extra $11,250.

The catch: without plan adoption, the extra $11,250 remains out of reach regardless of age eligibility, making verification essential.

Can I put 100% of my salary into a 401k?

Contribution limit based on compensation

  • You can contribute up to 100% of your salary, but the dollar limit ($23,500 for under 50) or the total limit ($70,000) will cap you first.

IRS rule: deferrals cannot exceed 100% of compensation

  • Total contributions (employee + employer) cannot exceed the lesser of 100% of your compensation or the section 415(c) limit (IRS — 401(k) and profit-sharing plan contribution limits).

Practical limitations and employer policies

  • Many employers cap deferrals at 50-75% of salary to avoid issues with Social Security and other deductions. Check your plan’s specific rules.

The trade-off: While technically you can contribute 100% (up to the dollar limit), in practice you’d need to fund living expenses from savings because your paycheck would go to zero. Most people aim for 15-20% over the year to reach the max.

  • Whether future legislative changes will affect catch-up rules beyond 2026.

Key perspectives

“The 401(k) limit increases to $24,500 for 2026, IRA limit increases to $7,500.”

IRS — News release IR-2025-111

IRS — Retirement topics: Catch-up contributions

For the millions of Americans in their early 60s who are behind on retirement savings, the super catch-up is a rare opportunity to accelerate contributions. But it requires action now — check your plan’s adoption before you rely on that extra $11,250. The 2026 limit of $24,500 is already set, so planning early avoids year-end scrambles.

Frequently asked questions

What is the 401k limit for 2024?

The 2024 employee deferral limit was $23,000, with a $7,500 catch-up for age 50+.

Can I contribute to both a 401k and an IRA in 2025?

Yes. The 401(k) limit ($23,500) and IRA limit ($7,000, plus $1,000 catch-up if 50+) are separate. You can max both.

What happens if I exceed the 401k contribution limit?

You must withdraw the excess and any earnings by the tax filing deadline (including extensions) or face a 6% excise tax on the excess.

Is the 401k limit per employer or total across all jobs?

The $23,500 deferral limit is per person, not per plan. If you have multiple jobs, your combined deferrals cannot exceed that amount.

How do catch-up contributions work for those under 50?

They don’t. Catch-up contributions are available only to participants age 50 or older. The super catch-up for ages 60-63 is a further enhancement.

Are 401k contributions tax deductible?

Traditional 401(k) contributions are pre-tax, reducing your taxable income. Roth 401(k) contributions are after-tax; withdrawals are tax-free.

When is the deadline to contribute to a 401k for 2025?

Generally, your elective deferrals must be made by December 31, 2025. Employer contributions can be made up to the corporate tax deadline.
