Robert Lee씨는 질문을 U.S. Army 은퇴 사무국 Benefit Department에서도 알수있읍니다. Robert 씨 께서 주신 정보로 볼때, Robert씨는 1984년 이후 U.S. Army에서 일을 시작하였기때문에, Social Security Tax를 지불하였기에 염려하시는 Windfall Elimination Provision으로 이하여 Social Security Retirement benefit 이 Offset을 하지않습니다. 아래의 정보를 읽어보시고 도움이 되었으면 좋겠습니다.
Up until 1984, workers for the federal government were covered under the Civil Service Retirement System (CSRS). If you worked for a federal agency during these years, you did not pay Social Security tax on your earnings and you were not covered by Social Security.
But in 1984, a second retirement system, the Federal Employees Retirement System (FERS), was introduced. Federal workers under FERS are covered by Social Security because they pay Social Security taxes. Also, some workers covered by CSRS chose to switch to FERS. They, too, pay Social Security taxes and are therefore covered provided that they have 40 credits.
Both workers under FERS and CSRS are covered under the Medicare program because they pay Medicare taxes on their federal earnings.
