The Social Security Administration will be cutting some American’s checks in half starting later this month to recoup nearly $72 billion in improper payments. People who have received more Social Security benefits than needed can expect their monthly payments to be cut in half by around July 24 until the overpayment is repaid.

Starting in July, the federal agency will start withholding 50% of a person’s check if they’ve received an overpayment of their benefits. The withholding, officially part of what’s known as the Treasury Offset Program, will remain until the extra benefits are repaid.

Some Americans are seeing their Social Security payments cut by as much as 50% this month. Learn why, who’s at risk, and how to avoid future cuts.
