Public service pensions (PSP) are retirement benefits spouses receive from any local, state or federal governmental agency, other than SSA and the RRB. These benefits may be paid as either monthly payments or a lump-sum payment.
If you are entitled to, or will be entitled to, a PSP payment (or lump-sum payment that is more than just a refund of your own contribution to the pension fund), this will not apply to the Special Guaranty computation. Refer to booklet RB-30, Spouse/Divorced Spouse Annuity, for a more detailed explanation of the PSP.
