The following is an example of an underpayment with a SMI premium involved.
         A, a nonresident alien, is entitled to a RIB of $459.00 a month. A medical insurance
            premium of $24.80. He receives monthly checks of $365.20 ($434.00 (amount payable
            after SMI withholding) less $68.80 tax). In 6/88, A dies and his benefit check dated
            6/3/88 is returned uncashed. His widow, a nonresident alien, requests payment.
         
         The amount of the underpayment payable to the widow is $365.20—the amount of the returned
            check. A's MBR is corrected to show tax of $3.70 withheld for the medical insurance
            premium for 5/88. The balance of $65.10 ($68.80 less $3.70) is deleted from the MBR
            and PHUS records. This amount is posted as tax on the underpayment.
         
         
            
               NOTE:  If the widow had been a U.S. citizen, she would have received $434.00, the amount
                  payable to A before tax withholding.
