Do civil service employees receive Social Security?

Yes this is possible BUT the benefits may be reduced because of provision of the law. For more information, go to the SSA.gov web site and use the search box for Windfall Elimination Provision (Publication No. 05-10045).

If you receive a pension from employment in which you did not pay Social Security taxes and you also qualify for your own Social Security retirement or disability benefit, your Social Security benefit may be reduced, but not eliminated, by WEP. The amount of the reduction, if any, depends on your earnings and number of years in jobs in which you paid Social Security taxes, and the year you are age 62 or become disabled. In 2008, the maximum monthly reduction was $355.50.
