- You must make a new election each year—they do not restart automatically.
Starting in the year you turn 50, you may be eligible to make catch-up contributions to your TSP account in addition to your regular employee contributions.
Here’s what you should know:
Uniformed service members cannot use incentive pay, special pay, or bonus pay to make catch-up contributions. If you’re in a combat zone, catch-up contributions must be Roth.
To make a catch-up contribution election, use your agency’s or service’s payroll website (e,g., Employee Express, EBIS, LiteBlue, myPay, and NFC EPP) or complete Form TSP-1-C, Catch-Up Contribution Election (TSP-U-1-C for uniformed services members) and submit it to your payroll office. You may also download the form or call the ThriftLine at 1-877-968-3778 and press 3 to request a copy.
