# 1600.18 Separate service member and civilian contributions.

The TSP record keeper maintains uniformed services accounts separately from civilian accounts. Therefore, a participant who has made contributions as a uniformed service member and as a civilian employee will have two TSP accounts: A uniformed services account and a civilian account.
