If your Thrift Savings Plan is not being matched, the reason is almost always one of five things: you’re in a retirement system that doesn’t offer a match, you’re contributing less than 5% of basic pay, you’re a service member still inside the mandatory waiting period, you hit the annual IRS contribution limit early and shut off your own contributions for the rest of the year, or a payroll error broke the pipeline between your agency and the TSP. Each has a different fix, and a couple of them are easy to miss.
Start With Your Retirement System
The first thing to confirm is whether your system includes a match at all. Federal employees under the Civil Service Retirement System can contribute their own money to the TSP, but the government adds nothing on top.1U.S. Office of Personnel Management. CSRS Information CSRS was built around a more generous pension, and no TSP match was ever added to it.
The Federal Employees Retirement System is different. FERS participants receive both an automatic 1% contribution and matching each pay period.2U.S. Office of Personnel Management. FERS Information If you transferred from CSRS to FERS, agency automatic and matching contributions should have begun the same pay period the transfer took effect.3eCFR. 5 CFR Part 1600 – Employee Contribution Elections, Investment Elections, and Automatic Enrollment Program
Military members face a parallel split. Those under the legacy High-3 retirement system can contribute to the TSP, but the Department of Defense does not contribute to those accounts.4Military OneSource. Blended Retirement System Only members enrolled in the Blended Retirement System receive service automatic and matching contributions. If you entered service before January 1, 2018 and did not opt into BRS during the 2018 enrollment window, you are in the legacy system, and no personal contribution amount will produce a match.
You Have to Contribute at Least 5% of Basic Pay
For FERS and BRS participants, the match is tiered. The first 3% of basic pay you contribute is matched dollar-for-dollar, and the next 2% is matched at 50 cents on the dollar.5The Thrift Savings Plan (TSP). Contribution Types Contribute 5% and the government adds 4% in matching plus the 1% automatic, for a combined 5% from the agency. Contribute anything less and you leave part of that 4% behind every pay period. Contribute zero and only the automatic 1% shows up.
Since October 2020, new FERS employees have been auto-enrolled at 5%, which captures the full match from day one.6Federal Retirement Thrift Investment Board. 2024 Annual Report of the Thrift Savings Plan But if you lowered your rate later, matching drops the same pay period. Check your Leave and Earnings Statement or myPay to see what your election actually is right now.
Basic Pay Only, Not Bonus or Special Pay
This one catches service members. The match is calculated on basic pay. Contributions from incentive pay, special pay, or bonus pay go into your TSP account, but they don’t count toward the 5% threshold that unlocks the match.5The Thrift Savings Plan (TSP). Contribution Types A service member who elects 5% from bonus pay but 0% from basic pay receives zero matching. To get any match at all, the contribution must come from basic pay.
New Service Members: The Waiting Period Is Normal
Even inside BRS, matching does not begin on day one. The two government contributions have different timelines.
The service automatic 1% starts after you complete 60 days of service, no later than the first full pay period after that milestone.7The Thrift Savings Plan (TSP). Revision to Implementation of the Blended Retirement System If you’ve passed 60 days and still don’t see it, raise it with finance.
Service matching has a much longer wait. You become eligible after two years and one day of service, measured from your Pay Entry Base Date, with matching starting no later than the first full pay period after that date.7The Thrift Savings Plan (TSP). Revision to Implementation of the Blended Retirement System If you’ve been in uniform for less than that, the absence of matching is expected. The only government money in your account during those first two years is the automatic 1%.
Did You Hit the Annual IRS Limit Early?
This is the fix that saves people the most money, because the people who lose out here are the ones trying hardest to save. For 2026, the IRS elective deferral limit is $24,500 for participants under age 50.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Once your contributions hit that ceiling, employee contributions stop for the rest of the year. And because matching is calculated per pay period based on what you actually contributed that pay period, your match stops too.5The Thrift Savings Plan (TSP). Contribution Types
Front-load enough to hit $24,500 by September and you spend the last seven pay periods contributing nothing and receiving nothing. The fix is to divide the annual limit by 26 pay periods (about $942 for 2026) and set a flat dollar amount that spreads evenly across the full year.
Catch-Up Contributions If You’re 50 or Older
If you’re 50 or older, you can contribute past the base limit. The TSP uses a spillover method: once you hit the regular limit, additional contributions automatically count toward your catch-up allowance. For 2026, the catch-up limit is $8,000 for ages 50–59 and 64 and older, and $11,250 for ages 60–63 under SECURE Act 2.0.9The Thrift Savings Plan (TSP). 2026 TSP Contribution Limits
Catch-up contributions still receive matching, up to the 5% of basic pay threshold.10The Thrift Savings Plan (TSP). Contribution Limits But the same front-loading trap exists at higher amounts. The TSP specifically warns participants who drop from the $11,250 tier to the $8,000 tier (turning 64) to lower their contribution amount at the start of that year, or they will max out early and lose matching for the remaining pay periods.
Are You Looking in the Wrong Balance?
If you contribute to the Roth TSP and see no match in your Roth balance, the match isn’t missing. All agency and service contributions, both the automatic 1% and the matching, go into your traditional TSP balance regardless of whether your own contributions are Roth.11The Thrift Savings Plan (TSP). Traditional and Roth TSP Contributions This is a tax law requirement. Your Roth election controls only your own money; the government’s share is always traditional. Check the traditional side of your account before assuming anything is wrong.
If None of the Above Applies, It’s a Payroll Error
When the structural explanations don’t fit and matching is still absent, a payroll or data-transmission problem is the likely cause. These errors cluster around transitions: moving between agencies, converting from active duty to civilian employment, or returning from extended leave. Data sync between an agency’s HR system and the National Finance Center or another payroll provider can lag or break.12National Finance Center. Thrift Savings Plan Assistance
Compare two records. Your Leave and Earnings Statement shows what was deducted from your pay. Your TSP account shows what was actually deposited. If the LES reflects a deduction but the TSP account shows no corresponding match, the problem is in the transmission between your agency and the TSP record keeper. Contact your servicing personnel or finance office to open a correction.
File Within Six Months
You can file a claim to correct a missing contribution at any time, but the timing changes what happens next. If you submit within six months of the error, the Board or record keeper must correct it promptly. After six months, correction is at their discretion.13eCFR. 5 CFR 1605.22 – Claims for Correction of Board or TSP Record Keeper Errors; Time Limitations Check your account every pay period. Six months goes by faster than you think, and proving a correction should happen is much harder than proving it must happen.
