• A Thrift Savings Plan (TSP) is the defined‑contribution retirement plan available to U.S. federal civilian employees and uniformed service members (including the Ready Reserve). It functions much like a private‑sector 401(k): participants make pre‑tax (traditional) or after‑tax (Roth) contributions via payroll, choose how to invest them among TSP funds, and receive tax‑deferred growth (or tax‑free qualified Roth withdrawals). The plan is administered by the Federal Retirement Thrift Investment Board (FRTIB). (Source: Investopedia/TSP)
Key takeaways
– TSP is the federal government’s version of a 401(k) with low fees and a limited set of index funds.
– 2024 employee contribution limit: $23,000; 2025 limit: $23,500.
– Catch‑up contributions for participants age 50+ are $7,500 (2024 and 2025); an expanded catch‑up ($11,250) applies to ages 60–63 starting in 2025.
– Federal employer matching (for FERS) can add up to 5% of pay; CSRS employees do not receive matching.
– TSP offers six core funds (G, F, C, S, I and Lifecycle “L” funds) and a mutual fund window under conditions. (Source: Investopedia)
How the TSP works (overview)
1. Contribution elections: You elect a percentage (or dollar amount) of pay to contribute. These can be traditional (pre‑tax) or Roth (post‑tax).
2. Employer contributions: If you are a FERS employee, the agency automatically contributes 1% of pay and matches employee contributions up to a defined schedule (see Employer Matching).
3. Investment selection: You allocate contributions among the TSP investment options (G, F, C, S, I or one of the L funds).
4. Tax treatment and growth: Traditional contributions reduce current taxable income and grow tax‑deferred; Roth contributions are made with after‑tax dollars and qualified withdrawals are tax‑free.
5. Withdrawals/rollovers: At separation, retirement, or in‑service under some rules, you may take withdrawals, roll over funds to an IRA or new employer plan, or leave the money in TSP.
TSP investment options (what you can invest in)
– G Fund (Government Securities Investment Fund): short‑term Treasury securities specially issued to the TSP; principal protection and steady returns relative to other TSP funds.
– F Fund (Fixed Income Index Fund): a bond/index‑based fund that tracks a broad U.S. bond index.
– C Fund (Common Stock Index Fund): mirrors the performance of a large‑cap U.S. stock index (S&P 500).
– S Fund (Small Cap Stock Index Fund): tracks U.S. stocks not included in the S&P 500 (small‑ and mid‑caps).
– I Fund (International Stock Index Fund): tracks a broad international equity index (non‑U.S. markets).
– L Funds (Lifecycle or Target‑Date Funds): diversified portfolios made from the five individual funds, adjusted automatically for an investor’s time horizon. Good for “set it and forget it” investors.
– Mutual Fund Window: available to participants who meet minimums (e.g., at least $40,000 in the TSP) and other rules; allows limited investment in outside mutual funds (no more than a certain percent of account). (Source: Investopedia/TSP)
Contribution limits and catch‑up rules (2024–2025)
– 2024 employee deferral limit: $23,000.
– 2025 employee deferral limit: $23,500.
– Catch‑up for age 50+: $7,500 in both 2024 and 2025.
– Special higher catch‑up: beginning in 2025, workers aged 60–63 may be eligible for a larger catch‑up amount ($11,250).
– Important: These limits apply to employee elective deferrals; total limits (including employer non‑elective contributions and other special catch‑ups) may be subject to different rules. (Source: Investopedia)
Employer matching and contributions
– FERS employees:
• Automatic 1% non‑elective contribution from the agency regardless of whether you contribute.
• Agency matches dollar‑for‑dollar on the first 3% you contribute, and 50¢ on the dollar for the next 2% — for a potential agency match up to 5% of pay if you contribute at least 5%.
– CSRS employees: do not receive agency matching contributions.
– Explanation: Contribute at least 5% of pay to maximize the agency match under FERS. (Source: Investopedia)
Fees and expenses
– TSP fees are very low and transparent. Typical total plan administrative and investment fees are small (historically around the low‑hundredths of a percent range); Investopedia reports fees around 0.05% (check current disclosures for exact current ratios).
– Low fees are one of the TSP’s biggest advantages relative to many IRAs or 401(k)s. (Source: Investopedia/TSP)
Withdrawals, penalties, and RMDs
– Early withdrawals before age 59½ generally carry a 10% federal penalty (in addition to income tax) for traditional balances, but TSP may allow penalty‑free withdrawals if you separate from service in or after the year you turn 55 (the “rule of 55”). For certain FERS provisions, the penalty‑free age can be 50.
– Required Minimum Distributions (RMDs) apply starting at age 73 (rules changed via recent legislation; confirm current age and specifics before acting).
– TSP distribution options differ from an IRA in that TSP has structured periodic payments (monthly/quarterly/annual installments) and life‑expectancy based options; check the TSP website or Thriftline for the exact distribution choices available to you.
– Roth TSP: Qualified Roth distributions are tax‑free if they meet Roth rules. (Source: Investopedia/TSP)
Rollovers and portability
– You can roll qualified 401(k) and IRA assets into a TSP if you become a federal employee and meet TSP rollover rules.
– If you leave federal service, you can roll TSP assets to an IRA or to a new employer plan (if the receiving plan accepts rollovers), take a distribution (tax consequences apply), or leave funds in TSP if eligible.
– Evaluate taxes, fees, investment choices, and creditor/ERISA protections when deciding whether to roll over. (Source: Investopedia)
Is a TSP the same as a 401(k)?
– Not exactly—but they are similar. TSP is the federal government’s defined‑contribution plan (the government’s equivalent to a 401(k)). Contribution limits and tax treatments are comparable to 401(k) plans. A worker can have both a TSP and a private 401(k) (from different employments). (Source: Investopedia)
TSP vs. IRA — key differences and when to use each
– Contribution limits: TSP allows much higher employee deferrals ($23k+ in 2024 vs. $7k to IRAs in 2024).
– Employer match: TSP (FERS) provides employer match; IRAs do not have employer matches (except SEP/SIMPLE IRAs).
– Investment choices and flexibility: IRAs typically offer a far wider universe of investments; TSP limits you to its core funds plus the mutual fund window under conditions.
– Fees: TSP fees are generally much lower than many retail IRA funds; however, low‑cost IRAs exist if you choose index funds/ETFs.
– Withdrawals and rules: TSP has specific distribution options and may have favorable penalty exceptions (e.g., separation at 55), while IRAs allow flexible withdrawals (subject to taxes/penalties).
– Practical takeaway: Use the TSP to capture the match and high deferral limits, and consider an IRA for additional diversification or investment choices if you have extra savings. (Source: Investopedia)
What happens to your TSP if you quit federal service?
Options when you leave federal employment:
– Leave it in the TSP (if your balance is above the plan’s minimum for retention) and continue to manage investments there.
– Roll it over to a traditional or Roth IRA (depending on tax status) — be mindful of tax withholding rules and conversion taxes.
– Roll it to a new employer’s plan (if that plan accepts rollovers).
– Take a distribution (tax and potential penalties apply).
Practical considerations: keep track of beneficiary designations and ensure contact information is up to date so the plan can contact you after separation. (Source: Investopedia/TSP)
Practical steps — How to enroll, manage, and use your TSP
1. Enroll and set up account
• New federal hires: complete your agency’s payroll election form to designate contributions (traditional and/or Roth) and percent of pay.
• Create an online TSP account at tsp.gov to view balances, change allocations, and set beneficiaries.
• Set your contribution percent high enough to get the full agency match (if you’re under FERS, aim for at least 5%).
2. Choose traditional vs. Roth
• Traditional contributions reduce current taxable income; Roth contributions are taxed now and tax‑free at withdrawal (if qualified).
• Consider current tax bracket versus expected tax rate in retirement when deciding mix.
3. Select investment allocation
• If you want simple, choose an L (Lifecycle) fund that matches your expected retirement date.
• If you want control, build an allocation among G, F, C, S, I to match risk tolerance and time horizon.
4. Set beneficiaries
• Designate primary and contingent beneficiaries online to ensure assets pass according to your plans.
5. Monitor and rebalance
• Review allocations annually or after major life changes; TSP provides tools to move future contributions or rebalance current holdings.
6. Consider rollovers carefully
• Compare fees, investment options, creditor protections, and tax implications before rolling TSP money out after separation.
7. Plan distributions ahead of retirement
• Understand available distribution options (installments, partial withdrawals, single sums or rollovers) and RMD rules to avoid surprises.
8. Get help when needed
• Use the Thriftline, AVA (virtual assistant), and Message Center for questions and account changes.

Practical scenarios and quick guidance
– New federal employee who wants easy diversification: enroll, contribute at least 5% to capture the full FERS match, select an L fund that matches your expected retirement year.
– Mid‑career employee with sizable savings wanting more options: maintain TSP for low fees and match; open an IRA for additional securities/strategies and potential tax benefits.
– Leaving federal service near retirement: compare rolling to an IRA vs leaving in TSP based on fees, withdrawal flexibility, and whether you need creditor protections afforded by a government plan.
Tips and important reminders
– Always contribute enough to get the full agency match if you are a FERS employee — it’s free money.
– Keep beneficiary designations current; they override wills for TSP assets.
– Review fees and fund performance occasionally—even though TSP fees are low, allocations matter for long‑term outcomes.
– Before rolling funds out of TSP, calculate tax consequences and compare alternatives.
– Confirm current contribution limits, RMD ages, and distribution rules each year—tax law changes can adjust these thresholds. (Source: Investopedia/TSP)
