Making Your Decision
Before you decide how to allocate your new contributions, visit Investment Funds. You'll find information about the TSP fund options, performance, and expenses.
Making Your Contribution Allocation
Most participants use the website or the ThriftLine. These methods allow your request to be processed more quickly and efficiently.
Confirming Your Request
You will receive a confirmation of your request in the mail. If you make your request on the website, you will have the option of receiving an e-mail informing you that your transaction was processed. You will then be able to go to the My Account section of the website to review the details of your transaction.

Investing Your TSP Account Contributions


If you are a civilian and you were enrolled on or after September 5, 2015, or you are BRS participant, then unless you choose another investment option, all contributions received by the TSP will be deposited into the Lifecycle (L) Fund most appropriate for your age.*

If you are a civilian who enrolled before September 5, 2015, or you are a non-BRS uniformed services member, then until you choose another investment option, all contributions to your account will be deposited into the Government Securities Investment (G) Fund

If you are rehired after a break in Federal service, a number of factors affect how new contributions to your account will be invested. Refer to the “Welcome Letter” you receive from us after you are rehired for more information. It is especially important for you to review your statements to ensure your money is being invested according to your wishes.

If you would like new money coming into your account to be invested differently, you can make a contribution allocation.

Your contribution allocation tells us how you want new money going into your account to be invested among the TSP investment fund options. New money may be your own contributions, your agency/service contributions (if you are a FERS or BRS participant), your TSP loan payments, and any transferred or rollover funds from other retirement plans. You can make a contribution allocation at any time.

Keep the following in mind:

  • Your contribution allocation will not affect the money that is already in your account. To manage those funds, visit Interfund Transfers. For more information, view our Changing How You're Invested video.
  • Your contribution allocation will remain in effect until you submit another contribution allocation request.
  • If you have a traditional balance and a Roth balance in your TSP account, you cannot make a separate contribution allocation for each balance.
  • Any new money will be deposited proportionally according to your fund allocation at the time the money is deposited into your TSP account.

Making or Changing Your Contribution Allocation


There are several ways that you can make or change your contribution allocation.


Visit My Account: Contribution Allocations . You will need your account number (or user ID) and your Web password.


Call the ThriftLine. You will need your TSP account number and your 4-digit Personal Identification Number (PIN).
