Indiana Child Support FAQ

How is child support calculated in Indiana?

Indiana uses the income shares model under Ind. Child Support Rules & Guidelines: both parents’ incomes are combined, a basic obligation is determined, and each parent is responsible for their proportional share. The paying parent’s share becomes the support order.

Does Indiana use gross or net income for child support?

Indiana calculates support on gross (pre-tax) income as defined in Ind. Child Support Rules & Guidelines.

Can a Indiana court order more or less than the guideline amount?

Yes. The guideline amount under Ind. Child Support Rules & Guidelines is presumptive, not absolute - courts may deviate with written findings for factors like extraordinary medical or educational needs, other children supported, or very high income beyond the guideline range.

How do I apply for or modify child support in Indiana?

Apply through the Indiana child support agency or the family court in your county. Existing orders can be modified on a substantial change in circumstances - typically a significant income change, job loss, or a change in custody.
