Changes to catch-up contributions

The process for catch-up contributions is now easier for TSP participants. If you’re turning 50 or older, you’ll no longer need to make separate catch-up elections to your TSP account to contribute toward the catch-up limit.

Here’s how it works:

Important note for members of the uniformed services

If you are a uniformed services member and enter a combat zone, your contributions toward the catch-up limit must be Roth. (The TSP cannot accept traditional tax-exempt contributions toward the catch-up limit.) You also cannot contribute toward the catch-up limit from incentive pay, special pay, or bonus pay.

If you are contributing to both a civilian and uniformed services account, the limits apply to the total you contribute to both accounts during the year.

  1. For Blended Retirement System (BRS) participants: If you have reached the annual addition limit, your contributions toward catch-up will not be matched. (The IRS does not allow participants who have reached the annual addition limit to receive any more matching for the year.)
