Social Security can take up to 50% of a monthly retirement, survivor, or disability benefit to recover an overpayment. That can turn a $2,000 monthly benefit into a $1,000 payment until the debt gets repaid.
The 50% figure sounds final. It is not necessarily the only repayment arrangement available. If that withholding would make it difficult to cover ordinary expenses, Social Security allows beneficiaries to request a smaller amount each month. The request requires more than simply saying the deduction feels too high, though.
