The Social Security Administration (SSA) is set to start withholding up to 50% of monthly benefits from some recipients beginning in July. This move is part of the agency’s effort to recoup overpayments made to beneficiaries in recent years.

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. Wednesday, July 23: Birth dates between the 21st and 31st of the month.

Here’s what you need to know about the new policy and how it will affect you.
