The Civil Service Retirement System (CSRS) is a special retirement plan for federal employees and was founded 15 years before Social Security.The CSRS was a stand-alone government pension program whose annuities were never meant to supplement Social Security benefits. Hence, federal employees can receive both CSRS annuity and Social Security benefits.
However, how much you can receive in Social Security benefits depends on the period when you worked for the federal government. This is because federal workers who contributed to the CSRS before 1984 were not charged Social Security taxes on their annuities; thus, their Social Security earnings appear blank.
