Congress created the Federal Employees Retirement System (FERS) in 1986, and it became effective on January 1, 1987. Since that time, new Federal civilian employees who have retirement coverage are covered by FERS.

FERS is a retirement plan that provides benefits from three different sources: a Basic Benefit Plan, Social Security and the Thrift Savings Plan (TSP). Two of the three parts of FERS (Social Security and the TSP) can go with you to your next job if you leave the Federal Government before retirement. The Basic Benefit and Social Security parts of FERS require you to pay your share each pay period. Your agency withholds the cost of the Basic Benefit and Social Security from your pay as payroll deductions. Your agency pays its part too. Then, after you retire, you receive annuity payments each month for the rest of your life.

The TSP part of FERS is an account that your agency automatically sets up for you. Each pay period your agency deposits into your account amount equal to 1% of the basic pay you earn for the pay period. You can also make your own contributions to your TSP account and your agency will also make a matching contribution. These contributions are tax-deferred. The Thrift Savings Plan is administered by the Federal Retirement Thrift Investment Board.
