When parents separate or divorce, one of the most important financial issues is child support. In Texas, child support is designed to ensure that children continue to receive financial support from both parents, even when they live in separate households.
If you are going through a custody case in Texas, it’s important to understand how guideline child support works, how it’s calculated, and when the court may deviate from the guidelines.
How Texas Calculates Guideline Child Support
Texas law uses a percentage of net resources to determine the amount of child support the paying parent (known as the “obligor”) will owe to the receiving parent (the “obligee”).
As of 2025, the general guideline percentages are:
| Number of Children | Percentage of Net Resources |
| 1 child | 20% |
| 2 children | 25% |
| 3 children | 30% |
| 4 children | 35% |
| 5 children | 40% |
| 6+ children | Not less than 40% |
Net resources include most forms of income such as wages, salary, commissions, bonuses, self-employment income, and certain benefits. The court deducts items such as federal income tax, Social Security tax, union dues, and the cost of the child’s health insurance before applying the guideline percentage.
Texas also applies a maximum cap on monthly net resources, which adjusts every six years based on inflation. The most recent legislation in 2025 raised the maximum cap to $11,700 of monthly net resources.
When Courts May Deviate from Guidelines
The guidelines are a starting point, but the court can order a different amount if it’s in the best interest of the child. Factors that may lead to a deviation include:
- Extraordinary medical or educational expenses
- Special needs of the child
- The amount of time each parent has possession of the child
- Travel costs for visitation
- Other proven needs of the child
Duration of Child Support
In most cases, child support continues until the child turns 18 years old or graduates from high school, whichever happens later. Support may last longer if the child has a disability requiring continued care.
