Frequently asked questions

How does Texas calculate child support guidelines?

Texas applies a flat percentage to the paying parent's monthly net resources: 20% for 1 child, 25% for 2, 30% for 3, 35% for 4, and 40% for 5 or more children, capped at the statutory net resource ceiling ($9,200/month).

How does the Income Shares model calculate support in Florida and California?

Income Shares combines both parents' net incomes to determine the total basic child support need from state economic tables, then apportions the payment based on each parent's proportional share of combined income and physical overnight custody percentages.

Is child support tax-deductible or taxable in the US?

No. Child support payments are neither tax-deductible for the payer nor taxable gross income for the recipient parent under IRS rules.

How are health insurance premiums and childcare costs factored in?

Courts require that medical insurance and work-related childcare (daycare) expenses be added to the basic support schedule and apportioned between the parents in proportion to their incomes.
