For millions of retirees and disabled Americans, a Social Security check is not extra income—it is the money that keeps the lights on and groceries in the kitchen. That is why recent changes involving Social Security overpayments are causing panic among many older adults. The Social Security Administration recently announced that some new overpayment cases could once again face up to 100% withholding of monthly benefits to recover debts owed to the agency. Many recipients say they never even realized they were overpaid until a letter suddenly arrived demanding thousands of dollars back. If you receive one of these notices, understanding your Social Security overpayment rights could help you avoid financial disaster and potentially reduce or stop repayment entirely.
