An overpayment happens if Social Security pays you too much SSI or SSDI. Social Security will send you a letter telling you that you have an overpayment. The letter should tell you:
- how much you have been overpaid,
- how the overpayment happened,
- the dates the overpayment happened,
- how you can repay the overpayment,
- and your rights to appeal the overpayment and to request a waiver of the overpayment.
