You will need your remittance ID in order to repay your Social Security overpayment on Pay.gov. Using your bank's online bill pay feature, to make a payment to "Social Security Administration." • Send us a check for the entire amount of the overpayment. If you have an overpayment debt, you may be eligible to make a full or partial payment using Pay. Gov or your bank's online bill pay option. If the client does not have copies of the Notice of Overpayment(s), then the advocate needs to follow up with a Social Security District Office.
