TSP Super Catch-Up 2026: $35,750 Limit for Ages 60-63 | Fed Pilot
If you’re a federal employee between 60 and 63 years old in 2026, you have a once-in-a-career opportunity to save dramatically more in your Thrift Savings Plan — and most feds don’t even know it exists. The SECURE 2.0 Act created a special, higher catch-up contribution limit for a narrow four-year age window, and 2026 is the second year it’s in effect. Workers ages 60, 61, 62, and 63 can contribute up to $11,250 in catch-up contributions, on top of the standard $24,500 elective deferral limit, for a combined maximum of $35,750.
The short answer: Federal employees who turn 60, 61, 62, or 63 in 2026 can contribute up to $35,750 to TSP — a $24,500 standard limit plus an $11,250 super catch-up created by SECURE 2.0 Act § 109. The window lasts exactly four years per employee. Workers with prior-year FICA wages above $150,000 must make all catch-up contributions as Roth.
Key Takeaways
- The 2026 TSP super catch-up limit is $11,250, replacing the standard $8,000 catch-up for employees who turn 60–63 during the calendar year (IRS Notice 2025-67; TSP Bulletin 25-3).
- Combined with the $24,500 standard limit, the maximum TSP contribution for eligible employees is $35,750 in 2026.
- Employees whose 2025 FICA wages exceeded $150,000 must make all catch-up contributions as Roth — no pre-tax option (SECURE 2.0 § 603).
- You do not need a separate catch-up election. TSP’s spillover method automatically reclassifies contributions above $24,500 as catch-up.
- The agency 5% match is unaffected — it applies only to the first 5% of basic pay and is not extended to catch-up amounts.
What Are the TSP Contribution Limits for 2026?
There are three distinct TSP contribution tiers in 2026, set by IRS Notice 2025-67 and detailed in TSP Bulletin 25-3:
- Standard elective deferral limit: $24,500 for all employees regardless of age (up from $23,500 in 2025).
- Standard catch-up contribution: An additional $8,000 for employees ages 50–59 and 64 and older, for a combined maximum of $32,500.
- Super catch-up (SECURE 2.0 § 109): Replaces the $8,000 catch-up with $11,250 for employees who reach age 60, 61, 62, or 63 during the calendar year — combined maximum of $35,750.
The TSP applies the same statutory limits as 401(k) plans under Internal Revenue Code §§ 402(g) and 414(v).
How Does the Age 60–63 Super Catch-Up Window Work?
The super catch-up is available only in the calendar years during which you reach ages 60, 61, 62, or 63. Once you turn 64 — even in January — you revert to the standard $8,000 catch-up for that entire year.
Eligibility is based on the age you reach during the calendar year, not your age on January 1. A federal employee who turns 60 in December 2026 qualifies for the full $11,250 super catch-up for all of 2026. Using TSP’s published birth-year table: employees born 1963–1966 are eligible for the super catch-up in 2026; those born 1962 or earlier (age 64+) or 1967 and later (under 60) are not.
That birthday-anywhere-in-the-year rule creates a front-loading opportunity: an employee turning 60 in late 2026 should set their contribution rate high early in the year to ensure the full $35,750 limit is captured before any year-end payroll adjustments.
How Much More Can You Save With the Super Catch-Up?
The difference between the super catch-up ($11,250) and the standard catch-up ($8,000) is $3,250 per year. Over the full four-year window, that’s roughly $13,000 in additional contributions — plus growth.
A concrete example: a federal employee earning $135,000 currently maxing the standard catch-up at age 58 contributes $32,500 ($24,500 + $8,000), or about 24% of basic pay. When they enter the super catch-up window at 60, their limit jumps to $35,750. Assuming a 6% average annual return and 20 years of retirement, the extra $13,000 in contributions grows to roughly $41,500 by age 83 — meaningful additional withdrawal capacity when Medicare out-of-pocket costs typically peak.
Does the Super Catch-Up Change the Roth vs. Traditional TSP Decision?
Yes — and for high earners, the choice is made for them. Starting January 1, 2026, employees whose prior-year (2025) FICA wages exceeded $150,000 must make all catch-up contributions as Roth. They cannot make pre-tax catch-up contributions. TSP uses Box 5 (Medicare wages and tips) on your 2025 W-2 to determine eligibility. The $150,000 threshold is indexed up from the original $145,000 per TSP Bulletin 25-3.
For employees below the threshold, the super catch-up amplifies the existing Roth vs. Traditional decision. Federal employees nearing peak earning years often benefit from pre-tax contributions now, while employees planning for a low-income window in early retirement may prefer Roth contributions to reduce a future conversion ladder. See our companion post on Roth TSP vs. Traditional TSP for the full decision framework.
How Do Federal Employees Enroll in the Super Catch-Up?
TSP contributions are set through your agency payroll system, not TSP.gov. The process:
- Log into your agency payroll portal (Employee Express, MyPay, LiteBlue, GRB Platform, or your agency equivalent).
- Locate the TSP contribution election and set a percentage or flat dollar amount per pay period.
- Calculate your per-pay-period target. For 2026: $35,750 ÷ 26 pay periods = ~$1,375 per pay period (or ~$1,324 for a 27-pay-period year).
- Specify Roth, Traditional, or a split — TSP accepts both within the same election.
- Submit before the effective pay period. Most agencies take effect the following pay period.
No separate catch-up election is required. Since 2021, TSP has used a spillover method: once your contributions exceed the $24,500 standard limit, the excess is automatically reclassified as catch-up contributions up to your applicable limit. Set your contribution to hit the total — TSP handles the categorization.
Does the Super Catch-Up Affect Your 5 Percent Agency Match?
No. The agency match structure is unchanged. You still receive the 1% automatic contribution plus up to 4% matching on your first 5% of basic pay. Contributions above $24,500 — including all catch-up amounts — are not matched.
One important nuance: because TSP’s spillover keeps contributions flowing past $24,500 on a per-pay-period basis, you still receive the 5% match on every paycheck throughout the year — as long as your total contributions don’t reach $35,750 before December. Front-loading too aggressively early in the year can cause you to hit the limit in October, leaving two months with zero TSP deductions and zero agency match.
Which Federal Employees Benefit Most From the Super Catch-Up?
Three scenarios where the super catch-up has the highest impact:
1. Late Savers Closing a Gap
Federal employees who began contributing meaningfully to TSP in their 40s or 50s can use the four-year window to substantially boost account balances before retirement. An employee who hits 60 with $400,000 in TSP and maxes contributions for four years could add roughly $143,000 in contributions plus growth.
2. Employees Building a Roth Conversion Bridge
Those planning to retire at 62–63, defer Social Security to 70, and convert TSP to Roth during low-income years benefit from maximizing Roth TSP during the super catch-up window — reducing the size of the future taxable conversion. See our piece on TSP in-plan Roth conversions for the full strategy.
3. Employees Bridging to Social Security
Federal employees who plan to retire at 62 with FERS and draw down TSP before Social Security begins at 70 need a robust balance to fund the gap years. The super catch-up window typically lines up with the last four working years — the most direct opportunity to fuel that bridge.
What Should You Check in Your Pay Statement After Enrolling?
Verify two things in your first few pay statements after updating your TSP election:
- Your TSP deduction matches your target. Payroll errors during catch-up transitions are common. Confirm the dollar amount or percentage is exactly what you elected.
- Catch-up contributions above $24,500 are coded as Roth if your prior-year FICA wages exceeded $150,000. TSP’s spillover should handle this automatically, but high earners should confirm the classification before quarter-end.
If anything looks off, contact your agency payroll office promptly. Correcting before W-2s are issued is significantly easier than after.
Frequently Asked Questions
What happens if I turn 64 partway through 2026 — do I lose the super catch-up for the whole year?
Yes. Eligibility is determined by the age you reach during the calendar year. If you turn 64 at any point in 2026, you are not eligible for the super catch-up that year and revert to the $8,000 standard catch-up limit.
Can I split super catch-up contributions between Roth and Traditional TSP?
Yes — unless your prior-year 2025 FICA wages exceeded $150,000. If they did, SECURE 2.0 § 603 requires all catch-up contributions to be Roth. Below that threshold, you can allocate freely between Roth and Traditional.
Does the TSP super catch-up apply to CSRS-covered employees?
Yes. CSRS employees who participate in TSP are subject to the same IRS contribution limits as FERS employees.
If I retire mid-year at age 62, can I still use the super catch-up for the months I worked?
Yes, for pay periods during which you are employed. Contributions stop at separation. The annual limit is not prorated, so front-loading earlier in the year maximizes contributions before your retirement date.
Is the TSP super catch-up permanent, or does it expire?
It is permanent under SECURE 2.0 (no sunset provision). The dollar amounts adjust annually for inflation; the IRS announces updated figures each fall via a Notice (the 2026 limit came from IRS Notice 2025-67).
What if my agency’s payroll system caps my deduction below $35,750?
Contact your agency payroll office immediately. TSP’s spillover handles catch-up categorization automatically, but some systems have hard caps requiring a manual override. Request written confirmation before the pay period closes.
The super catch-up is a four-year window, and you get one shot at it. Federal employees in the 60–63 age range in 2026 can shelter an additional $13,000+ in TSP over those years — a direct boost to account balances heading into retirement. If you’re in or near the eligible age range, recalculate your contribution percentage today.
