Understanding the Thrift Savings Plan (TSP)

Understanding the Thrift Savings Plan

The initial search has provided a solid foundation for understanding the Thrift Savings Plan (TSP). Key information gathered includes:

What it is: A defined contribution retirement savings plan for federal employees and uniformed service members, similar to a 401(k).
Eligibility: Federal employees and members of the uniformed services, including Ready Reserve. Auto-enrollment at 5% for those hired on or after October 1, 2020.
Purpose: To help employees save for retirement with tax advantages and potential agency matching contributions.
Contribution Types: Traditional (pre-tax) and Roth (after-tax) options.
Investment Funds:
- Core Funds: G Fund (government securities, principal protection), F Fund (bond index), C Fund (S&P 500 index), S Fund (small-cap stocks), I Fund (international stocks).
- Lifecycle (L) Funds: Target-date funds that automatically adjust their mix of the five core funds over time, becoming more conservative as the target retirement date approaches. A new L 2075 Fund is being added, and the L 2025 Fund will merge with the L Income Fund starting June 30, 2025.
Contribution Limits: For 2025, the elective deferral limit is $23,500. Catch-up contributions for those 50 and older are $7,500. A special higher catch-up for ages 60-63 of $11,250 for 2025 due to SECURE Act 2.0. The total annual additions limit (employee + agency contributions) is $70,000 for 2025.
Withdrawal Rules:
- In-service withdrawals: Available for financial hardship or for those age 59½. Limits and potential penalties apply.
- Post-separation withdrawals: Options include partial distributions, total distributions, annuity purchases, and installment payments (fixed dollar amount or based on life expectancy).
- Required Minimum Distributions (RMDs): Generally begin at age 73 (increasing to 75 in 2033 for those born in 1960 or later) for separated participants.
Loan Program:
- Allows borrowing against own savings.
- Two types: General purpose (1-5 year repayment) and primary residence (up to 15-year repayment).
- Minimum loan $1,000. Maximum based on vested balance (up to 50% or $10,000, whichever is more, not exceeding $50,000 minus highest outstanding loan in past year).
- Interest rate is the G Fund rate of the previous month.
- Processing fees apply ($50 for general, $100 for residence).
- Repayments typically via payroll deduction.
- A proposed rule change (April 2025) would alter how accrued interest is combined with principal when reamortizing loans.
Matching Contributions: FERS employees can receive agency automatic (1%) and matching contributions (up to an additional 4% if contributing 5%). CSRS participants do not receive matching contributions. Agency contributions go to the Traditional TSP balance.
Rollovers: TSP accepts rollovers from other eligible retirement plans (like 401(k)s or IRAs), and TSP funds can be rolled over to other plans upon separation.
Management: Contribution allocations (for new money) and interfund transfers (for existing money) can be made online or by phone.
Recent Changes/News:
- New L 2075 Fund and L 2025 Fund merger (June 30, 2025).
- Proposed rule change for TSP loan reamortization formula (public comment period likely ended May 2025, but worth noting the proposal was made).
- SECURE Act 2.0 impacting RMD ages and catch-up contributions.
FAQs: Covered topics like changing investments, contribution methods (dollar vs. percentage), making contributions outside of payroll, contribution limits if retiring mid-year, loan impact on contributions, Roth matching, and Roth income limits (not applicable to Roth TSP). Cannot currently convert Traditional TSP to Roth TSP within the plan.

Decoding Your Retirement Savings: A Comprehensive Guide to the Thrift Savings Plan (TSP)

For federal employees and members of the uniformed services, the Thrift Savings Plan (TSP) is a vital component of their retirement strategy. This defined contribution plan, similar to a 401(k) in the private sector, offers a powerful way to save for the future with significant tax advantages and employer-matching contributions for many. Whether you’re new to federal service or looking to optimize your existing TSP, this guide will break down everything you need to know.

What is the Thrift Savings Plan (TSP) and Who is Eligible?

The TSP is a retirement savings and investment plan designed to provide federal employees, including members of the uniformed services and the Ready Reserve, with a secure financial future. Its primary purpose is to help you save for retirement, offering benefits such as:

Tax-deferred or tax-exempt growth: Depending on your contribution type (Traditional or Roth).
Agency/Service contributions: For eligible employees (primarily FERS and BRS members), your agency or service contributes to your account.
Low administrative and investment expenses.
A diverse range of investment options.

If you were hired (or re-hired) as a federal civilian employee on or after October 1, 2020, you are automatically enrolled in the TSP with a 5% deduction from your basic pay directed into the Traditional TSP. Members of the uniformed services covered by the Blended Retirement System (BRS) are also automatically enrolled. Even if automatically enrolled, it’s crucial to actively manage your account to align with your retirement goals.

Contribution Options: Traditional vs. Roth TSP

You have two main ways to contribute to your TSP, and you can even contribute to both:

Traditional TSP: Contributions are made on a pre-tax basis. This means your contributions are deducted from your pay before federal and, in most cases, state income taxes are calculated, lowering your current taxable income. The money in your Traditional TSP, including contributions and earnings, is taxed when you withdraw it in retirement.
Roth TSP: Contributions are made on an after-tax basis. You pay taxes on the money now, but qualified withdrawals in retirement (generally, if you’re 59½ or older and five years have passed since your first Roth contribution) are tax-free, including all earnings.

Important Note on Agency/Service Contributions: Any agency automatic (1%) and matching contributions you receive will always be deposited into your Traditional TSP balance, even if you only contribute to the Roth TSP. This is because agency contributions cannot be made on an after-tax basis for you.

Frequently Asked Questions (FAQs)

Q: How do I change where my new TSP contributions are invested?
- A: You need to make a “contribution allocation” through your My Account on TSP.gov or by calling the ThriftLine. This directs how new money is invested.
Q: How do I change how my existing TSP balance is invested?
- A: You need to request an “interfund transfer” through your My Account on TSP.gov or by calling the ThriftLine. This moves your current balance among the funds.
Q: Should I contribute a percentage of my pay or a specific dollar amount?
- A: If your goal is to maximize the agency/service match (e.g., contributing 5% for FERS), using a percentage is straightforward. If you’re trying to reach the maximum annual elective deferral limit, specifying a dollar amount per pay period might be more precise, ensuring you don’t hit the limit too early and miss out on matching contributions for the rest of the year.
Q: Can I contribute to my TSP from my bank account?
- A: No, TSP contributions must be made through payroll deductions from your federal civilian or uniformed services pay.
Q: If I retire before the end of the year, can I still contribute the full annual limit?
- A: Yes, you can contribute up to the IRS elective deferral limit for the year, regardless of when you retire, as long as your contributions don’t exceed your pay.
Q: Does having an outstanding TSP loan affect how much “new” money I can contribute?
- A: No, loan repayments are separate from your elective deferral contributions. You can still contribute up to the annual IRS limit.
Q: Do I still get agency matching if I only contribute to the Roth TSP?
- A: Yes. Your agency/service contributions will always go into your Traditional TSP balance, even if all your employee contributions go to your Roth TSP.
Q: Are there income limits for contributing to the Roth TSP, like with Roth IRAs?
- A: No, there are no income limitations for contributing to the Roth TSP.
Q: Can I convert my Traditional TSP balance to Roth TSP within the plan?
- A: Currently, the TSP does not allow for in-plan conversions of Traditional balances to Roth.
