Deductions provided for in Secs. 404.415, 404.417, and 404.421 (as modified in Sec. 404.458) are made by withholding benefits (in whole or in part, depending upon the amount to be withheld) for each month in which an event causing a deduction occurred. If the amount to be deducted is not withheld from the benefits payable in the month in which the event causing the deduction occurred, such amount constitutes a deduction overpayment and is subject to adjustment or recovery in accordance with the provisions of subpart F of this part.
