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).

USPHS Commissioned Corps needs to fill out the paper forms and not the electronic payroll system.

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.
