My wife is going to be under the GPO & WEP in filing for SS, so we don't expect much. But would both the GPO & WEP be in play if she should claim spousal benefits? And is there a tool out there that would figure out what her income will be with both of these programs that lessen her payout each month?

Phillip,
The WEP affects her retirement benefit and the GPO affects her spouse's benefit.
Our software, MaximizeMySocialSecurity (MMSS), fully accounts for bot the WEP and the GPO. You can easily see the effect of both the WEP and the GPO by running MMSS with her non-covered pensionand then by temporarily setting her pension as covered.

Thanks,
Mike
