Texas sets child support under Family Code chapter 154, applying statutory percentages to the paying parent’s net resources — this calculator uses the 2026 Office of the Attorney General tax charts to convert gross income to net resources. Net resources above the $11,700-per-month cap (effective September 1, 2025) aren’t automatically included in the guideline percentage; that’s where a court’s discretion comes in.
