Some Americans will see their Social Security checks drop by 50% after the Social Security Administration announced in April that it would start withholding payments from recipients who were overpaid starting at the end of July. Here’s what you need to know about the new policy and how it will affect you.

Regular Social Security retirement benefits for the month of July will be sent out on the SSA’s usual schedule: Wednesday, July 9: Birth dates between the first and 10th of the month. Wednesday, July 16: Birth dates between the 11th and 20th of the month.

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.
