The Thrift Savings Plan (TSP) remains one of the primary retirement savings tools available to federal employees and members of the uniformed services. Each year, the IRS reviews retirement plan contribution limits, and those changes can affect how much participants may be able to save through their TSP accounts.
For 2026, the TSP contribution limit increased from the 2025 level. Understanding the new limits, catch-up contribution rules, agency matching, and available TSP investment options can help participants make informed retirement savings decisions.
Because investment choices depend on factors such as time horizon, risk tolerance, and overall financial circumstances, there is no single TSP fund or allocation that is appropriate for everyone.
Yes. The annual contribution limit for the TSP increased in 2026.
For 2026, the IRS increased the elective deferral limit for participants in the federal government’s Thrift Savings Plan from $23,500 in 2025 to $24,500 in 2026.
The applicable catch-up limits also changed:
The enhanced catch-up provision applies to participants who attain age 60, 61, 62, or 63 during the calendar year.
These limits apply to eligible TSP participants and are subject to the applicable IRS and TSP rules.
| Contribution Type | 2025 | 2026 |
|---|
| Regular contribution limit | $23,500 | $24,500 |
| Age 50+ catch-up | $7,500 | $8,000 |
| Age 60–63 enhanced catch-up | $11,250 | $11,250 |
| Maximum with standard catch-up | $31,000 | $32,500 |
| Maximum for ages 60–63 | $34,750 | $35,750 |
The regular contribution limit increased by $1,000 for 2026. The standard catch-up limit increased from $7,500 to $8,000, while the age 60–63 enhanced catch-up remains $11,250 for 2026.
Increasing your TSP contributions can be an important part of a long-term retirement savings strategy. However, the appropriate contribution amount depends on your income, expenses, other retirement benefits, and financial goals.
If you want to contribute the full regular 2026 TSP limit of $24,500, spreading contributions throughout the year can make it easier to stay on track.
For example, over 26 pay periods, contributing approximately $942 per pay period would total about $24,500 before considering any catch-up contributions.
Your actual payroll amount may need to be adjusted based on your pay schedule and agency payroll system.
Federal employees covered by FERS may receive agency contributions to their TSP account.
The standard FERS structure includes:
This means contributing at least 5% of basic pay generally allows a FERS participant to receive the full agency matching contribution available under the TSP rules.
Before changing your contribution percentage, review your agency’s current TSP information and applicable plan rules.
Participants who receive agency matching contributions should consider how contribution timing affects their annual match.
Instead of making very large contributions early in the year, some participants may prefer to spread contributions across their pay periods.
For example, someone targeting the $24,500 annual limit could divide the target across their available pay periods rather than reaching the annual elective deferral limit well before the end of the year.
Your specific payroll schedule and agency matching rules should be considered when deciding how to structure contributions.
The TSP offers several core investment funds, each with different investment characteristics and levels of market risk.
Rather than labeling one fund as the “best” TSP fund, it may be more useful to understand what each fund is designed to do.
The C Fund invests in stocks of large U.S. companies and tracks the performance of the S&P 500 Index.
It may be considered by participants seeking long-term exposure to the U.S. large-cap stock market.
However, stock funds can experience significant short-term price fluctuations, and past performance does not guarantee future results.
The S Fund provides exposure to U.S. stocks outside the large-cap companies represented by the C Fund.
Because smaller companies can experience greater price volatility, the S Fund may carry more short-term investment risk than more conservative TSP options.
Participants should consider how much market volatility they are comfortable accepting before selecting an allocation.
The I Fund provides international stock market exposure.
International investments can provide diversification beyond U.S. stocks, but they can also involve additional risks, including currency fluctuations, political developments, and differences between international markets and the U.S. market.
For participants looking to diversify geographically, the I Fund can be an important option to understand.
The F Fund invests in a broad portfolio of U.S. investment-grade bonds and seeks to track the Bloomberg U.S. Aggregate Bond Index.
Bond investments can help provide diversification from stocks, although bond funds can also lose value when market conditions change.
Interest-rate movements, credit conditions, and other economic factors can affect F Fund performance.
The G Fund invests in special-issue U.S. Treasury securities available only through the TSP.
It is generally viewed as the most conservative of the TSP’s core funds and is designed to preserve principal while providing interest income.
The G Fund may be particularly relevant for participants who prioritize stability over stock-market growth potential.
The L Funds are professionally diversified portfolios designed around different retirement time horizons.
Their asset allocations automatically change over time, generally becoming more conservative as the target date approaches.
L Funds may be worth considering for participants who prefer a diversified, professionally managed allocation rather than selecting individual TSP funds themselves.
There is no single “best” TSP fund for every federal employee.
The appropriate investment mix can depend on factors such as:
For this reason, participants should be cautious about investment articles that claim one particular TSP fund will outperform the others.
A fund that performs well during one market environment may perform differently under another set of economic conditions.
Instead of following a single “best fund” recommendation, consider these general approaches.
Federal employees with several decades before retirement may have more time to withstand short-term market volatility.
Some participants in this stage may choose to emphasize stock funds while maintaining an allocation that fits their personal risk tolerance.
Mid-career participants may want to review whether their current TSP allocation still matches their retirement timeline.
This can be a useful time to consider diversification among U.S. stocks, international stocks, bonds, and government securities.
Employees approaching retirement may want to pay closer attention to portfolio volatility and how their TSP fits with other sources of retirement income.
A more conservative allocation may be appropriate for some participants, but the right decision depends on the individual’s circumstances.
A participant with a substantial FERS pension, Social Security income, and other assets may have a different risk capacity than someone relying more heavily on TSP withdrawals.
Federal employees may generally have the option to make contributions to either a Traditional TSP, Roth TSP, or a combination of the two, subject to applicable rules.
Traditional TSP contributions are generally made on a pre-tax basis. Taxes are generally paid when taxable distributions are taken.
Roth TSP contributions are made with after-tax money. Qualified Roth distributions can generally be tax-free if applicable requirements are met.
The choice between Traditional and Roth contributions can depend on your current tax situation, expected future tax rate, income, retirement plans, and other financial circumstances.
There is no universally correct choice for every federal employee.
One important retirement-planning development for 2026 involves catch-up contributions.
Under SECURE 2.0, certain participants with higher prior-year wages who make catch-up contributions may be required to make those catch-up contributions on a Roth basis.
For 2026, the applicable prior-year wage threshold is $150,000, subject to the specific rules that determine whether the requirement applies.
This is particularly important for federal employees who are eligible for catch-up contributions and should be considered when reviewing payroll and TSP contribution elections.
A TSP review does not necessarily mean making a major investment change.
Consider reviewing:
The TSP is only one part of a federal employee’s overall retirement strategy.
Depending on your circumstances, you may also consider:
A comprehensive retirement plan should consider how these pieces work together rather than evaluating the TSP in isolation.
The 2026 TSP elective deferral limit is $24,500.
Eligible participants age 50 and older can generally make an additional $8,000 catch-up contribution in 2026, bringing the potential total to $32,500.
Participants who attain age 60, 61, 62, or 63 during 2026 may be eligible for the enhanced catch-up limit of $11,250. With the $24,500 regular contribution limit, that can result in total contributions of up to $35,750, subject to applicable rules.
There is no single TSP fund that is best for every participant. The appropriate choice depends on factors such as investment time horizon, risk tolerance, retirement income needs, and overall financial circumstances.
Not necessarily. The C Fund provides exposure to large U.S. companies, but concentrating your entire TSP balance in one investment category may not fit every participant’s goals or risk tolerance.
The G Fund is generally considered the most conservative core TSP fund and is designed around special-issue U.S. Treasury securities. However, “safe” does not necessarily mean it will provide the highest long-term growth.
An L Fund may be worth considering if you prefer a diversified, professionally managed approach that adjusts its allocation over time. Whether it is appropriate depends on your retirement timeline and financial circumstances.
