When must the withholding begin?
Answer in detail:
The employer must start withholding from the affected employee's pay no later than the first pay period that occurs after 14 days following the date the notice was mailed. From then on, each time the employee is paid, the proper amount must be withheld and forwarded. If the employer is required to withhold child support income from more than one employee that is payable to the same clerk or agency, the employer may submit to such clerk one total amount each pay period for all affected employees so long as the portion of the payment attributable to each employee is specified.
