The Division of Child Support Enforcement is a state-run division of MDHS, delivering services through county-level offices reachable through the agency's office locator rather than independently run county programs.
The division locates noncustodial parents, establishes paternity, sets support orders, and collects and enforces payments once a case is active, coordinated through the statewide Call Center.
Mississippi uses the Percentage of Income (Flat) model to calculate support. See how this compares to other states →
Mississippi's default child support termination age is 21. See the full rules, including high school and disability extensions →

How to Apply for Child Support in Mississippi
A parent or caretaker of a child can apply for Mississippi child support services by calling the Child Support Call Center or visiting a local county office. Families already receiving TANF or Medicaid in Mississippi are typically referred for services automatically.
The application requires identifying information for both parents and the child, along with any existing custody or support paperwork. The division then works to establish paternity if needed and get a support order in place.
How to Collect Child Support Payments in Mississippi
Mississippi collects most support through income withholding once an order is active, disbursed to the receiving parent by direct deposit or debit card.
Payments can be tracked through the state's iPayOnline system, and mailed payments go to a separate SDU P.O. Box from the main MDHS headquarters address.
Missed Payments & Enforcement
Mississippi can intercept tax refunds, suspend licenses, and report arrears to credit bureaus when a parent falls behind, handled through the Call Center for case-specific enforcement questions.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500.
