The Thrift Savings Plan (TSP) is a Federal Government-sponsored retirement savings and investment plan. It offers the same type of savings and tax benefits that many private corporations offer their employees under "401(k)" plans.

Blended Retirement System (BRS) Members of the Uniformed Services
If you are a member of the uniformed services who began serving on or after January 1, 2018, your service automatically enrolled you in the TSP (or will) once you had served 60 days and 3% of your basic pay is deducted from your paycheck each pay period and deposited in the traditional balance of your TSP account, unless you have made an election to change or stop your contributions. You can make an election by following the instructions in Starting, Changing, and Stopping Your Contributions.

Non-BRS Members of the Uniformed Services
If you are a member of the uniformed services who is not covered by the Blended Retirement System (BRS), your account is established by your service after you make a contribution election using your service's automated system, if it has one. For example, most members of the uniformed services use myPay. If your service does not use an electronic system, you can complete Form TSP-U-1, Election Form and return it to your service.

Reentering Members of the Uniformed Services

If you were already in the BRS plan before you left the service—whether as a new member of the uniformed services or an opt-in—you will be automatically reenrolled when you reenter. If you were not in BRS but had fewer than 12 years of service when you left, your service may give you the opportunity to opt in when you reenter. In either case, assuming you had served 60 days before leaving, your enrollment will begin with the first pay period after reentering. If neither situation applies to you, you can still start a TSP account or resume contributing to your existing account as a non-BRS member. Follow the instructions in Starting, Changing, and Stopping Your Contributions.

Air Force Reserve Service members on active duty are eligible to contribute to the TSP. 

Basics: The TSP is a defined contribution plan. This means that the income service members receive from a TSP account depends on the amount contributed and the earnings on those contributions. This is unlike the Uniformed Services Retirement System in which the income received is based on years of service and the rank held at the time of retirement. If contributions from basic pay are made, one to 100% of any incentive pay or special pay (including bonus pay) may also be contributed, up to the limits established by the Internal Revenue Code (In 2024, that amount is $23,000). In addition to that amount, " Catch-up contributions " of up to $7,500 for 2024, may be made by eligible service members (age 50 or older or turning 50 during the calendar year). All funds contributed belong to the beneficiary, even if they do not serve the 20 or more years ordinarily necessary to receive uniformed services retired pay. 

Roth TSP: With the introduction of Roth TSP, service members have the potential for two types of balances in the TSP account: TSP and Roth TSP. The service member's own contributions can be designated as traditional TSP or Roth TSP. Roth contributions are taken out of the paycheck after income is taxed. When Roth funds are withdrawn, they are tax-free. Additionally, there are no taxes on the earnings as long as the service member is at least age 59 ½ (or disabled) AND the withdrawal is made at least five years after the beginning of the year in which the first Roth contribution was made.

The table below compares the treatment of traditional and Roth TSP contributions: The table below compares the treatment of the two different types of contributions.

¹ Roth contributions are subject to Federal (and, where applicable, state and local) income taxes, while traditional contributions are not taxed until withdrawn. However, both Roth contributions and traditional contributions are included in the amount of wages used to calculate payroll taxes (e.g., Social Security taxes).
² You would have to pay taxes on any pre-tax amount transferred to a Roth IRA.
³ Transfers to a Roth IRA from a Roth TSP are not subject to the income restrictions that apply to Roth IRA contributions.

How to Contribute: Service members are eligible for this benefit as soon as they join the uniformed service. Participation in the TSP is optional. To start contributing to the TSP, complete the TSP Election Form (TSP-U-1).

On this form, indicate the percentage of basic pay, incentive pay, special pay, or bonus pay to be contributed. Service members may also contribute to the TSP by signing up through the myPay website (https://mypay.dfas.mil/#/). Some percentage of basic pay must be contributed in order to contribute from incentive or special pay.

Tax Benefits: TSP contributions are "tax-deferred" from taxable pay, meaning that they are deducted before Federal and, in almost all cases, state income taxes are withheld. Therefore, taxable income is smaller and less is paid in taxes. In addition, Federal taxes are not paid on the money contributed until it is withdrawn from the TSP account. Any money earned over the years is also tax-deferred. This means that no income taxes are paid on TSP account contributions and earnings until the money is received - usually after retirement. The longer money is invested, the greater the benefit of tax-deferred earnings will be.

Flexibility: TSP offers a choice of funds in which to invest. For a description of these funds, including key features, historical returns, and a detailed description, please see https://www.tsp.gov/index.html. The TSP allows the investor to allocate contributions among the different funds based on the investor's personal preferences. It also allows the investor to change contribution allocations and transfer money between funds on a daily basis.

Withdrawing Funds: Service members are eligible, but not required, to withdraw from the TSP account as soon as they separate from the uniformed services. service members should be aware that there may be tax penalties for withdrawing funds prior to age 59½. For more information please consult the IRS TSP fact sheet. Previously, the law required that you make a full withdrawal election once you turned 70½ and were separated from federal service. If you failed to do that, we would initiate an account “abandonment” process. The new law that began September 15, 2019, does away with this requirement. You will never be required to make a full withdrawal election, and we will no longer abandon accounts as we have in years past. If your account has already been abandoned, you’ll be able to restore the account without making a full withdrawal election. Your restored balance can remain in the plan (subject To RMDs) with all the new withdrawal options available. Active Service members are not required to make withdrawals, regardless of age. Payments can be deposited directly into checking or savings accounts. The TSP can also transfer all or part of any single payment or, in some cases, a series of monthly payments, to a traditional IRA or eligible employer plan. As of September 15, 2019, you now have more options for how and when you can access money from your TSP account. These options fall into the following categories:

• After you separate from service, you can take multiple post-separation partial withdrawals

• If you are 59½ or older and still working in federal civilian or uniformed service, you can take up to four in-service withdrawals each year

• You will be able to choose whether your withdrawal should come from your Roth balance, your traditional balance, or a proportional mix of both

• You will no longer need to make a full withdrawal election after you turn 70½ and are separated from federal service (You will still need to receive IRS required minimum distributions (RMDs))

• If you are a separated participant, you will be able to take monthly, quarterly, or annual payments

• You will be able stop, start, or make changes to your installment payments at any time

• You will have enhanced online tools to help you make withdrawals in the My Account section of https://www.tsp.gov/index.html.

Regulations: TSP regulations are published in title 5 of the Code of Federal Regulations, Parts 1600 - 1690, and are periodically supplemented and amended in the Federal Register.

Change in Required Minimum Distribution Age:

The SECURE Act 2.0, which passed on December 29, 2022, increased the start age for required minimum distributions from 72 to 73 on January 1, 2023, and then further increases the start age to 75 on January 1, 2033. The law affects participants born after December 31, 1950.

Implementation of 5% Automatic Enrollment Percentage for Thrift Savings Plan Participants

On October 1, 2020, the Federal Retirement Thrift Investment Board (FRTIB) will increase the automatic enrollment percentage from 3% to 5% of pay for all Federal Employees Retirement System (FERS), Civil Service Retirement System (CSRS), and Blended Retirement System (BRS) participants who are automatically enrolled in the TSP on or after October 1, 2020, and for BRS participants automatically re-enrolled in the TSP on or after January 1, 2021, per 5 CFR § 1600.34 and 1600.37. The Thrift Savings Plan Enhancement Act of 2009 grants the FRTIB the authority for this change. This change will not affect the contribution rates in place for FERS and CSRS participants who were automatically enrolled in the TSP prior to October 1, 2020, or BRS participants who were automatically enrolled prior to October 1, 2020, and did not terminate their contributions.
