The Thrift Savings Plan (TSP) is a retirement savings plan that you can keep no matter where your career takes you. This article will answer common questions about signing up for the TSP, explain how to keep your information current, and share some facts about your investment options.

How do I sign up for the TSP?

1.       Log into myPay. You’ll see a special section “TSP section” — click there. 

2.       Make a contribution election. A contribution election tells your service how much of your pay you want to contribute to your TSP account, and if that money should be considered pre-tax (traditional) and/or after-tax (Roth). 

3.       While you’re in the TSP section of myPay, don’t forget to enter your birth date and current mailing address. Whenever you need to update your address, just log into myPay and enter it. You should know that the “Correspondence Address” section of myPay will NOT update your information with the TSP. It’s crucial that you keep your mailing address up-to-date to receive important TSP account information.

How do I access my TSP account after signing up?

After you sign up for your TSP account in myPay, the TSP will mail a Web password to the address the TSP has on file. Use this password with your TSP account number when you log into the My Account section of tsp.gov

You’ll also receive a ThriftLine Personal Identification Number (PIN) in the mail shortly after you sign up for the TSP. You’ll need this PIN to access your account information and perform certain transactions on the ThriftLine, the TSP’s automated telephone service. (Your ThriftLine PIN is not the same as your myPay PIN.)

Where do I find more information about investing my TSP contributions? 

Begin in the Planning & Tools section of tsp.gov.  There you’ll find information about investment strategies as well as questions to ask yourself before you make your decision.  Then visit Investment Funds, where you’ll find an overview of all of the TSP Funds, including our Lifecycle (L) Funds, which take away a lot of the investment guesswork.  To invest in the L Fund that’s right for you, or choose your own investment mix of the TSP’s five individual funds, log into My Account.

I’ve heard a lot about Roth IRAs. Are Roth TSP and Roth IRA contributions the same thing?

Short answer? No. There are some important differences between Roth TSP and Roth IRA contributions:
