How Texas Calculates Child Support

Under the Percentage of Income model, Texas calculates child support based on a fixed percentage of the noncustodial parent's income. This model is straightforward: the obligor pays a set percentage that increases with the number of children. The custodial parent's income is generally not factored into the basic calculation.

The simplicity of this model means the calculation is relatively straightforward. The key variable is the noncustodial parent's adjusted income. For one child, the obligor pays 20% of their income. For two children, it increases to 25%, and so on.

Key Factors in Texas Child Support

Texas courts consider several factors when determining child support obligations:

  • Healthcare costs
  • Dental insurance
  • Multiple family adjustment
  • Net resources cap
  • Social Security benefits
  • Number of children requiring support
  • Each parent's gross income
  • Parenting time / overnight schedule

Self-Support Reserve

Texas protects a self-support reserve of $1,080/month to ensure the paying parent can meet their own basic needs. If the obligor's income falls below this threshold, the court may reduce or suspend the child support obligation.

Texas Child Support Income Cap

Texas applies an income cap of $184,620/year (approximately $15,385/month) for child support calculations. Income above this cap may be treated differently โ€” courts have discretion to apply the standard guidelines percentage or deviate based on the children's needs and the family's standard of living.

If your combined household income exceeds $184,620, the court may consider additional factors such as the children's established lifestyle, educational needs, and extraordinary expenses.

Shared Custody in Texas

Texas's shared custody threshold is 40% of overnights (approximately 146 nights per year). When the noncustodial parent has the child for at least this many overnights, the standard child support calculation is adjusted downward to reflect the direct spending that occurs during parenting time.

The more overnights the noncustodial parent has beyond the 40% threshold, the greater the reduction in child support. In a true 50/50 custody arrangement, the higher-earning parent typically pays the difference between what each parent would owe based on their income share.

Can Texas child support be modified?

Yes. Either parent can petition the court to modify child support when there has been a substantial change in circumstances. Common reasons include a significant increase or decrease in either parent's income (typically 15-25%), a change in the custody arrangement, a change in the child's medical or educational needs, or a change in childcare costs. The modification takes effect from the date the motion is filed, not retroactively.

How long does child support last in Texas?

In most cases, Texas child support obligations continue until the child turns 18. Support may be extended if the child is still attending high school (typically until age 19 or graduation, whichever comes first). If the child has a disability that prevents self-support, the obligation may continue indefinitely. Some states also allow support through college โ€” check Texas's specific statutes.

What if a parent doesn't pay child support in Texas?

Texas takes child support enforcement seriously. The state child support agency can pursue several remedies including automatic wage garnishment, interception of federal and state tax refunds, suspension of driver's and professional licenses, denial of passport applications, seizure of bank accounts, placement of liens on property, and contempt of court proceedings that can result in fines or incarceration. Unpaid child support also accrues interest in most cases.
