Civil Service Retirment System (CSRS)

The Civil Service Retirement Act, which became effective on August 1, 1920, established a retirement system for certain Federal employees.  It was replaced by the Federal Employees Retirement System (FERS) for Federal employees who first entered covered service on and after January 1, 1987.

The Civil Service Retirement System (CSRS) is a defined benefit, contributory retirement system.  Employees share in the expense of the annuities to which they become entitled. CSRS covered employees contribute 7, 7 1/2 or 8 percent of pay to CSRS and, while they generally pay no Social Security retirement, survivor and disability (OASDI) tax, they must pay the Medicare tax (currently 1.45 percent of pay).  The employing agency matches the employee's CSRS contributions.

CSRS employees may increase their earned annuity by contributing up to 10 percent of the basic pay for their creditable service to a voluntary contribution account.   Employees may also contribute a portion of pay to the Thrift  Savings Plan (TSP).  There is no Government contribution, but the employee contributions are tax-deferred.
