How Child Support is Calculated in Texas
Texas uses a Percentage of Income model — one of only a handful of states that does. The non-custodial parent (called the 'obligor') pays a flat percentage of net resources, scaling from 20% for one child up to 40% for five or more. Net resources are gross income minus a standardized federal tax deduction.
Estimated Monthly Child Support in Texas
Below are sample calculations using our Texas formula. These figures assume the higher-earning parent pays support and exclude childcare or insurance add-ons.
| Your Income | Other Parent | 1 Child | 2 Children | 3 Children |
|---|---|---|---|---|
| $3,000/mo | $3,000/mo | ~$450 | ~$563 | ~$675 |
| $4,000/mo | $2,500/mo | ~$600 | ~$750 | ~$900 |
| $6,000/mo | $3,000/mo | ~$900 | ~$1,125 | ~$1,350 |
What Can Increase or Decrease Payments in Texas?
- The obligor's monthly net resources after federal tax estimate
- The number of children before the court
- Other children the obligor is legally required to support
- Health and dental insurance premiums for the children
- Whether the obligor's income exceeds the statutory cap (currently around $9,200/mo net)
- Any proven extraordinary needs of the child
How to File for Child Support in Texas
- Open a case with Texas's Department of Child Support Services (or the equivalent state agency).

- Submit a parenting plan or custody order showing each parent's overnight time.
- Attend a hearing or administrative review where a judge or referee finalizes the order.
Frequently Asked Questions — Texas Child Support
Does Texas use both parents' income?
No. Texas's standard guideline only considers the non-custodial parent's net resources. The custodial parent's income is generally not factored in unless the obligor argues for a deviation.
Is there a Texas child support cap?
Yes. Guideline percentages apply only up to the first ~$9,200 of monthly net resources. Income above the cap may still trigger additional support if the child's proven needs require it.
How is 'net resources' calculated in Texas?
Texas uses a tax-table approach: gross income minus federal income tax (calculated as if single, one exemption), Social Security, Medicare, union dues, and the children's health insurance.
When does Texas child support end?
Support ends at age 18 or graduation from high school, whichever is later. It continues indefinitely for an adult child with a disability that began before age 18.
