Windfall Elimination Provision and Surviror Benefits

Here are excerpts from a paper on the Windfall Elimination Provision that may be of interest :

Almost half of the retired workers affected by the WEP received a federal pension, and another 36 percent received either a state or local pension.

The WEP computation reduces the PIA for some retired and disabled workers and their spouses and children. It is the PIA of record. However, the WEP computation does not apply to survivor benefits. If a worker dies, benefits for widow(er)s and children are based on the regular PIA.
