Frequently Asked Questions

How is child support calculated in Texas?

Texas uses a percentage of income model, which means child support is calculated based solely on the paying parent's (obligor's) net monthly resources. The custodial parent's income is not considered in the basic calculation. Specific percentages are applied based on the number of children: 20% for 1 child, 25% for 2 children, 30% for 3 children, 35% for 4 children, and 40% for 5 or more children.

What percentage is child support in Texas?

Texas child support percentages are: 20% for 1 child, 25% for 2 children, 30% for 3 children, 35% for 4 children, and 40% for 5 or more children. These percentages are applied to the obligor's net monthly resources up to $11,700 per month (as of September 1, 2025).

Does 50/50 custody reduce child support in Texas?

No, Texas does not automatically reduce child support for 50/50 custody arrangements. Even with equal parenting time, one parent is designated as the possessory conservator and typically pays support to the managing conservator. A reduction requires filing a petition for deviation with the court, and the judge has discretion to grant or deny the request.

How long do you pay child support in Texas?

In Texas, child support typically ends when the child turns 18 AND graduates from high school, or when the child turns 19, whichever comes first. Support can extend indefinitely for children with disabilities who are unable to support themselves. Support also ends if the child gets married, joins the military, or becomes legally emancipated.

Can child support be modified in Texas?

Yes, child support can be modified in Texas under three main circumstances: (1) a material and substantial change in circumstances, (2) three years have passed since the last order, or (3) the obligor's net resources have changed by at least $100 per month or 20% (whichever is less). You must file a petition with the court to request a modification.

What is the income cap for Texas child support?

The Texas child support income cap is $11,700 per month in net resources (effective September 1, 2025). The statutory percentages apply to income up to this cap. For income above the cap, the court has discretion to order additional support based on the child's needs and the circumstances of the parents.
