I retired under CSRS, which is the correct retirement coverage for me. Why am I affected by Government Pension Offset?
The Government Pension Offset is part of the Social Security Law that reduces spouse or survivor Social Security benefits for certain individuals who are also entitled to a Federal Government pension. If you retire from the Federal service under CSRS and are also eligible for Social Security benefits as a spouse, former spouse or survivor, your Social Security benefit will be reduced. It is reduced because you are receiving a pension from the Federal Government based on earnings that are not covered by Social Security. For every $3 you receive from your CSRS annuity, your Social Security spousal benefit is reduced by $2. For more information, see SSA's publication, Government Pension Offset at http://www.ssa.gov/pubs/10007.html.
