TSP is a retirement savings and investment plan for Federal employees and members of the uniformed services, including the Ready Reserve. It was established by Congress in the Federal Employees' Retirement System Act of 1986 and offers the same types of savings and tax benefits that many private corporations offer their employees under 401(k) plans.
TSP is a defined contribution plan, meaning that the retirement income you receive from your TSP account will depend on how much you (and your agency, if you are eligible to receive agency contributions) put into your account during your working years and the earnings accumulated over that time.
