If You're Between 60 and 63, You Have Until December 31 To Take This 401(k) Advantage

As retirement nears, maximizing your tax-advantaged savings becomes a race against the clock. If you celebrate your 60th, 61st, 62nd, or 63rd birthday by Dec. 31, 2026, the SECURE 2.0 Act introduced an enhanced "super" catch-up contribution rule to maximize your senior benefits.

However, this perk comes with a strict expiration date, meaning eligible workers must act quickly to avoid missing out. Here is everything you need to know.

Editor's note: Retirement contribution limits and SECURE 2.0 provisions are based on current IRS and federal guidance for 2026.

The 401(k) advantage you may be missing

The SECURE 2.0 Act established a unique "super" catch-up provision specifically for savers aged 60 to 63.

Under SECURE 2.0, beginning in 2025, individuals ages 60 to 63 are eligible for increased catch-up contributions in their 401(k), 403(b), and governmental 457(b) plans, commonly known as super catch-up contributions. It is designed to give pre-retirees a final, aggressive opportunity to build wealth just before retirement.

How much you can contribute in 2026

The IRS increased the standard 401(k) contribution limit to $24,500 for 2026. Workers aged 50 and older may make an additional $8,000 catch-up contribution.

For workers ages 60 through 63, the catch-up limit rises to $11,250 instead of the standard $8,000. That brings the total potential contribution to $35,750 for 2026, assuming your plan allows the enhanced catch-up provision.

Understanding the SECURE Act 2.0

The SECURE 2.0 Act, signed in December 2022, introduced over 90 retirement rule changes. Key provisions include raising the required minimum distribution (RMD) age from 72 to 73, and eventually to 75 by 2033.

It expanded access to emergency savings within plans and allowed student loan repayments to qualify for employer matching. SECURE 2.0 also mandates after-tax Roth catch-up contributions for high earners, with the rule taking effect in 2026.

How the super catch-up limit is calculated

SECURE 2.0 raises the catch-up limit for participants ages 60 to 63 to the greater of $10,000 or 150% of the standard age 50 catch-up contribution limit. For 2025 and 2026, the enhanced limit is $11,250, which is the greater of $10,000 or 150% of $7,500.

Both the regular and super catch-up limits are indexed for inflation so that the amounts may adjust upward in the future.

The window is short, and it closes permanently at 64

The super catch-up provision is only available to workers ages 60 through 63. That means if you turn 64 in 2027, 2026 is your last year of eligibility. 

The window doesn't pause or extend. Workers who don't use it by Dec. 31 of their last eligible year simply lose the opportunity and the compounding growth those additional contributions would have generated.

It applies to more than just 401(k)s

The higher catch-up contribution limit applies to employees who turn 60, 61, 62, or 63 and participate in most 401(k), 403(b), governmental 457 plans, and the federal government's Thrift Savings Plan.

For SIMPLE IRA plans, the higher catch-up contribution limit is $5,250 for workers aged 60 to 63, compared to the standard $4,000 for those aged 50 and older.

Your employer must opt in

The law makes the super catch-up an optional feature for employers. Each plan sponsor decides whether to implement the super catch-up in their retirement plan.

If your employer hasn't adopted the provision, you won't be able to contribute the higher amount even if you're eligible by age. The first step is confirming with HR or your plan administrator whether the super catch-up is available in your specific plan.

High earners face a Roth requirement in 2026

Beginning in 2026, participants of plans with Roth features offering catch-up contributions must make catch-up contributions on a Roth basis if prior-year wages with the plan sponsor exceeded $150,000.

That means catch-up contributions, including the super catch-up, are made with after-tax dollars for affected workers. The trade-off is tax-free growth and tax-free withdrawals in retirement, which could be advantageous depending on your expected future tax rate.

How to adjust your payroll elections before year-end

Taking advantage of the super catch-up requires action on your part. You may need to review your payroll contribution elections through your employer. If you're paid biweekly, you have roughly 26 pay periods in 2026.

To reach $35,750, you'd need to contribute approximately $1,375 per pay period. Adjusting elections earlier in the year spreads the impact more manageably.

What the extra contributions are worth over time

The super catch-up isn't just about this year's tax deduction. On a $3,250 additional contribution invested at 7% annually, the growth over 10 years is approximately $6,400. Over 15 years, it's roughly $8,960. And that's just one year's extra contribution.

Workers who maximize the super catch-up for all four eligible years contribute an additional $13,000 above standard catch-up limits across that window.

Bottom line

If you're between 60 and 63 in 2026, the super catch-up is one of the few retirement savings advantages that expires permanently based on age. 

To stretch your retirement dollars further, use this period to boost contributions while also paying down high-interest debt. Every dollar you shelter in a tax-advantaged account today is a dollar that may continue working for you throughout retirement.
