  • Starting in January 2021, we’re making the process easier for participants. If you’re turning 50 or older and are eligible for catch-up, you’ll no longer need to make separate catch-up elections to your TSP account. To learn how to make these contributions next year, visit Catch-up contributions.

Start, change, or stop contributions

In most cases, you’ll use your agency’s or service’s electronic payroll system to start, change, or stop your TSP contributions.

For example, civilian payroll systems include Employee Express, EBIS/GRB, LiteBlue, myPay, and NFC EPP.

Uniformed services can use myPay (Army, Air Force, Navy, Marine Corps) or Direct Access (Coast Guard and NOAA Corps).

Does your agency accept paper forms?

Download Form TSP-1, Election Form (TSP-U-1 for uniformed services members), or call the ThriftLine at 1-877-968-3778 and choose option 3 to have it mailed to you.

I was just hired. Am I already contributing?

If you were hired or rehired on or after October 1, 2020, you were automatically enrolled in the TSP at 5% of your salary. You are getting the full match from your agency or service. If you decrease your employee contribution amount below 5%, you will not receive the full amount of agency money. If you stop making regular employee contributions, your matching contributions will also stop.
