Navigating child support in Texas means dealing with a strict formula-driven process managed under the Texas Family Code. Rather than guessing what a court might order, state guidelines rely on precise statutory calculations, specific monthly income caps, and standardized deductions. Understanding how these mechanics operate helps parents prepare realistic financial expectations during custody disputes or modification requests.
The core of every standard child support calculation in Texas is the noncustodial parent's monthly net resources. State law applies a flat percentage based on the number of children before the court, capped at a statutory maximum income threshold. While judges retain discretion to deviate from these guidelines when special circumstances arise, most standard cases follow predictable mathematical rules.
Calculating Monthly Net Resources
Before applying any percentage, courts determine the paying parent's net resources. Gross income includes wages, salary, commissions, overtime, tips, bonuses, dividends, net rental income, and self-employment earnings.
Texas law subtracts specific items from gross income to arrive at net resources:
- Federal income tax calculated using single tax status and standard deductions
- Social Security taxes or mandatory retirement contributions
- Union dues
- The cost of health insurance and dental insurance premiums for the children
Unlike many states, Texas does not look at actual take-home pay stub numbers. It uses statutory deductions to establish a standardized baseline. You can review official calculation frameworks directly through the Texas Office of the Attorney General.
Guideline Percentages and Income Caps
Once net resources are calculated, the state applies standard percentage guidelines. The statutory cap on monthly net resources sits at $11,700, following an adjustment that replaced the older $9,200 limit. Standard percentages apply to net resources up to this ceiling:
- One child: 20 percent (maximum standard payment of $2,340 per month)
- Two children: 25 percent (maximum standard payment of $2,925 per month)
- Three children: 30 percent (maximum standard payment of $3,510 per month)
- Four children: 35 percent (maximum standard payment of $4,095 per month)
- Five children: 40 percent (maximum standard payment of $4,680 per month)
- Six or more children: Not less than the amount for five children
For parents earning above the $11,700 net resource cap, standard guidelines stop applying automatically. To secure higher support payments, the receiving parent must prove that the child has specific, demonstrable needs that justify exceeding the statutory cap.
Multiple-Family Adjustments
Life changes, and many parents support children across different households. Texas handles this through a multiple-family adjustment chart found in the Family Code. If an obligor has legal a duty to support children in another household besides the ones involved in the current case, the standard guideline percentages decrease.
For example, a parent paying support for two children before the court while also legally supporting three other children in a separate household will see their percentage drop from 25 percent to a lower adjusted rate. This ensures parents aren't stretched beyond their financial capacity across multiple legal obligations.
Medical and Dental Support Requirements
Child support in Texas involves more than monthly cash transfers. Courts routinely order the noncustodial parent to provide medical and dental support.
Typically, one or both parents are ordered to maintain health and dental insurance for the children through an employer or private plan. If the paying parent secures the insurance, the actual cost of insuring the children is factored in as a deduction when calculating net resources. If the custodial parent provides coverage, the noncustodial parent usually pays cash medical support to reimburse a share of that monthly premium. Uninsured medical expenses, such as copays or orthodontia, are generally split between parents on a percentage basis, often 50-50.
Modifying an Existing Child Support Order
Life circumstances shift, jobs end, and children grow older. An existing child support order doesn't change automatically when your income drops or when statutory caps rise. You must file a formal motion for modification with the court.
To win a modification, you must prove a material and substantial change in circumstances. Common grounds include:
- A job loss or significant change in salary lasting longer than three years since the last order
- Changes in the cost of health insurance for the child
- A change in the amount of time the child spends with each parent
- The emancipation or aging out of a child
Courts also allow a review if it has been three years since the last order and the monthly support amount calculated under current guidelines differs by either 20 percent or $100 from the existing order.

Frequently Asked Questions
Does getting remarried affect my child support payments?
No. Under Texas law, the income of a new spouse cannot be used to calculate or modify child support obligations. The court evaluates only the financial resources of the biological or adoptive parents.
What happens if the paying parent falls behind on payments?
Unpaid child support accumulates as arrearages, which accrue interest by law. The Office of the Attorney General or private counsel can enforce orders through driver's license suspensions, passport denials, bank account levies, property liens, and contempt of court charges that carry potential jail time.
Can parents agree to a lower child support amount outside of court?
Parents can sign private agreements, but judges aren't bound by them. A court will reject any agreement that falls below state guidelines unless the parents provide a written justification showing why the deviation is in the best interest of the child.
How long does child support last in Texas?
Support generally continues until the child turns 18 or graduates from high school, whichever occurs later. If a child has a severe physical or mental disability, a court may order indefinite support.
