If the Social Security Administration sent you a notice about an overpayment you owe, you can make a secure payment here. Write a letter to the Social Security Administration.Tell them how much you can afford to pay each month. If we can't waive collection, we may use this form to decide how you should repay the money. Please answer the questions on this form as completely as you can. Appeal the Overpayment. The first part of the appeal is to forget about the 60 day window. The Notice of Overpayment will tell you how much you were overpaid. It will tell you to send the money back in 30 days. Receiving an overpayment letter from the SSA can be frightening.
