Federal Retirement Thrift Investment Board (FRTIB)

The Federal Retirement Thrift Investment Board (FRTIB) is an independent federal agency in the United States that administers the Thrift Savings Plan (TSP), a retirement savings and investment plan for federal government employees, including civilian employees and members of the uniformed services. The TSP is similar to a 401(k) plan in the private sector and allows participants to save for their retirement through various investment options.
