Idaho's Child Support Services is a state-administered division of the Department of Health and Welfare, handling cases statewide rather than through independent county agencies.
The division locates noncustodial parents, establishes paternity, sets support orders, and collects and enforces payments once a case is active, with the MyChildSupport portal handling most day-to-day case management online.

How to Apply for Child Support in Idaho
A parent or caretaker of a child can apply for Idaho child support services through the MyChildSupport portal or by contacting DHW directly. Families already receiving TANF or Medicaid in Idaho 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 Idaho
Idaho collects most support through income withholding once an order is active, disbursed to the receiving parent by direct deposit or debit card.
Payments can also be made through Idaho's Smart e-Pay portal, and both parents can check payment history and case status through MyChildSupport at any time.
Missed Payments & Enforcement
Idaho's enforcement tools include income withholding, license suspension, property liens, and passport denial for parents who fall behind on payments.
As in every state, federal law allows a passport to be denied or revoked once past-due support exceeds $2,500 — this is covered as part of the main services page rather than a separate enforcement URL in Idaho's case.

Contact information above covers what the Department of Health and Welfare – Child Support Services handles directly, but the guideline model, termination age, and modification rules that decide your amount live on the dedicated pages linked here. And if the other parent lives outside Idaho, interstate rules — not Idaho's own procedures — determine which state has authority.
