Relating to the application of child support guidelines to net resources in a suit affecting the parent-child relationship.

HB 2643 sets a $30,000 monthly cap on net income for calculating child support in Texas under the Family Code. It applies only to new custody or support cases filed on or after September 1, 2025, and repeals an existing subsection that previously allowed higher income levels to be considered. The bill directly affects parents required to pay child support and their children in court cases involving parental responsibility. It does not change existing calculations for cases filed before the effective date.
