Employers will receive an Income Withholding Order or an Electronic Income Withholding Order (IWO or E-IWO) to withhold payments for support from an obligor parent’s wages. In addition, the employer may receive a National Medical Support Notice (NMSN) to enroll the obligor parent’s child in health care coverage. It is the employer’s responsibility to provide a copy of the Order/Notice and the blank Request for Hearing form to the employee within 10 days of receipt. The employer must follow the terms of the Order/Notice and begin to withhold money from the employee’s net disposable earnings no later than 10 days after receipt. Deductions usually begin the next pay period after receipt of the Order/Notice.

For a comprehensive Employer Checklist for Child Support Withholding, please refer to the Employer Handbook.
