Child support in Texas is primarily governed by Chapter 154 of the Texas Family Code. As of September 1, 2025, the statutory cap for monthly net resources used to calculate guideline support increased from $9,200 to $11,700. This means for one child, the maximum guideline support is now approximately $2,340 per month (20% of the cap), representing a significant increase for high-earning parents. Support typically continues until the child turns 18 or graduates from high school, whichever occurs later. It is important to note that existing orders do not change automatically; a parent must file a Petition to Modify to reflect the new 2026 caps or changes in income. Failure to pay child support can result in severe penalties under the Texas Penal Code, including driver’s license suspension and possible jail time for contempt of court.
