How Can Workers Ages 60 Through 63 Use the Higher 2026 Catch-Up Contribution Before It Expires?

This is a narrow four-year window. The useful move is not simply selecting a bigger percentage in payroll. It is checking the age rule, the plan rule, the Roth rule, and the timing rule before the last payroll leaves no room to correct course.

Can I make the higher catch-up contribution if I turn 60 this year?

Yes. If you turn 60 during 2026, you fall within the age-60-through-63 group for the entire 2026 calendar year; eligibility is based on the age you reach by year-end, according to the Internal Revenue Service catch-up contribution guidance.

The same year-end test covers workers who turn 61, 62, or 63 in 2026. The date you enroll, change a payroll election, or receive your birthday does not split the limit into a before-and-after amount. The important question is simpler: what age will you be on December 31, 2026?

For eligible participants, the 2026 enhanced catch-up is $11,250 instead of the regular $8,000 catch-up, according to the IRS. It generally applies to 401(k), 403(b), governmental 457(b), and federal Thrift Savings Plan participants if their plans allow catch-up contributions.

All amounts in this table are 2026 limits reported by the IRS 2026 retirement-plan limit announcement. Plan terms can be lower. That is the operational constraint that deserves attention.

Run the payroll math before changing the election

Start with the amount already deferred in 2026, subtract it from the applicable 2026 ceiling, then divide the remainder by the paychecks left. For example, spreading the full $35,750 2026 combined employee limit over 26 paychecks produces a derived payroll target of $1,375 per paycheck, using the IRS's 2026 limit.

If contributions start later, the per-paycheck amount rises. A worker with 10 paychecks remaining would divide the remaining room by 10, not by a full year. That sounds obvious. It prevents the common error: treating an annual limit as if payroll will automatically catch up.

Do I lose the higher catch-up contribution when I turn 64?

Yes. Starting in the calendar year you turn 64, the enhanced catch-up ends and the regular $8,000 2026 catch-up limit applies instead, according to the Federal Retirement Thrift Investment Board.

The timing flips from the prior section. Turning 64 late in 2026 does not preserve the higher amount for part of the year; the regular limit applies for that whole 2026 calendar year. The distinction is easy to miss because eligibility is measured by year-end age, not the date a payroll system notices a birthday.

TSP participants have an additional practical issue. The TSP says contribution elections carry over annually unless a participant files a new election. A participant approaching age 64 can review the election early enough to avoid reaching the lower catch-up cap before year-end and potentially missing matching contributions. The same planning question belongs in any workplace plan: does the payroll system stop all deferrals when it reaches its cap, or does it handle the cap in another way?

Use a short administrator script: “I turn 64 in 2026. What is my 2026 catch-up ceiling in this plan, when will payroll stop deferrals, and how could that affect employer matching?” That gets the three details that matter without asking for a vague estimate.

How much can someone age 60 to 63 contribute to a 401(k) in 2026?

Someone who turns 60 through 63 in 2026 can contribute up to $35,750 in employee elective deferrals and catch-up contributions to a 401(k), if the plan permits the enhanced catch-up, according to the IRS: $24,500 under the 2026 elective-deferral limit plus $11,250 under the enhanced catch-up limit.

That is not necessarily the total amount that can enter the account. The IRS reports a 2026 defined-contribution annual-additions limit of the lesser of $72,000 or 100% of compensation, excluding catch-up contributions; with eligible age-60-through-63 catch-up contributions, the IRS says the total can reach $83,250 in 2026. Employer contributions and plan-specific rules affect that broader calculation.

Keep the two ceilings separate. The $35,750 2026 figure is the employee deferral-and-catch-up frame. The $72,000 and $83,250 2026 figures are broader annual-additions figures. Mixing them creates bad payroll expectations.

Check the Roth catch-up rule before payroll closes

Beginning in 2026, a catch-up-eligible participant whose prior-year wages from the plan sponsor exceeded $150,000 must make catch-up contributions on a Roth basis when the plan offers catch-up contributions and Roth features, according to the IRS. The rule affects the catch-up portion, not the underlying 2026 $24,500 elective-deferral limit.

For a governmental 457(b), the IRS also identifies a $150,000 2026 indexed prior-year-wage threshold. It adds a sharper consequence: if an affected governmental 457(b) plan does not offer a Roth option, the participant cannot make age-50 catch-up contributions, although the plan's special final-three-years catch-up may still be pre-tax.

Before making a payroll change, ask: “Does this plan permit the $11,250 2026 enhanced catch-up?” “Is my prior-year wage amount above the $150,000 2026 Roth threshold?” “Can payroll distinguish regular deferrals from Roth catch-up contributions?” “What date must my election be processed to count in the 2026 plan year?” Short questions. Fewer avoidable surprises.

One final drill: open the latest pay statement, identify year-to-date retirement deferrals, count remaining paychecks, and send those four questions to the plan administrator this week. The higher limit is useful only if payroll can apply it before the 2026 window closes.
