An overpayment occurs when Social Security pays you more than you should have been paid. The notice will include the amount we overpaid you, the reason you were overpaid, and options to repay the overpayment, request an appeal or request a waiver.Follow the time limits given in your Notice of Overpayment. CP268 tells you we made changes to your return because we believe there is a miscalculation on your return. The process for doing this is to fill out and file a Request for Waiver and Recovery Questionnaire.
