Support payments must include the obligor's docket number and Master Participant Index (MPI) number. If employers withhold income for multiple employees they must specify the amount being withheld for each employee on the payment remittance form. The telephone number of a contact person for the employer must accompany payments. Employers have seven days from the date of withholding to submit child support payments for their employees, per G.S. 110-136.8(b). If employers fail to submit payments in a timely manner they can be subject to enforcement action for noncompliance.
