How Much Will I Have to Pay in Child Support in Texas? 

 Posted on June 07, 2026 in Child Support

When parents separate in Texas, child support is typically one of the first legal obligations that needs to be addressed. Texas uses child support guidelines based primarily on the paying parent's income, although courts can depart from those guidelines in some cases when doing so is in the child's best interest. 

Whether you are the parent who will be paying or the one who will be receiving support, understanding how the state arrives at the child support amount gives you a real advantage going into your case. If you are facing a child support order in 2026, a Houston, TX family law attorney can walk you through the numbers for your specific situation.

How Does Texas Calculate Child Support Payments?

Texas child support is based on the paying parent's net resources, not their gross income. Net resources are calculated by subtracting certain deductions allowed by Texas law from a parent's income, including Social Security and Medicare taxes, federal income tax calculated under a statutory formula, union dues, and the cost of the child's health and dental insurance coverage. Texas Family Code Chapter 154 lays out exactly what counts as income for this purpose. It is broader than just a paycheck, and it includes wages, self-employment income, rental income, interest, dividends, and certain benefits.

Once net resources are calculated, the court applies a fixed percentage based on how many children are involved:

• One child: 20 percent of net resources

• Two children: 25 percent of net resources

• Three children: 30 percent of net resources

• Four children: 35 percent of net resources

• Five or more children: 40 percent of net resources

Texas adjusts the income cap for these guidelines every six years based on inflation. Effective September 1, 2025, the percentages above apply to the first $11,700 of the paying parent's monthly net resources. If a parent earns more than the cap, the court can order additional support based on the child's proven needs, but the percentage guidelines do not automatically apply to the full amount above it.

Who Pays Child Support in Texas, and How Is the Amount Affected by Other Children?

Texas law treats the parent who has the child most of the time as already contributing financially to the child's daily costs of raising the child. The child support obligation, therefore, typically falls on the parent with less time with the child, the noncustodial parent. Payments typically go through the Texas Office of the Attorney General, which tracks each payment and maintains records for both parties.

If the paying parent is already supporting children from a prior relationship, the court takes that into account. The percentage applied is adjusted to reflect the total number of children the parent is financially responsible for across all cases, not just those in the current case. This can meaningfully change the final number, which is why it is important to give your attorney a complete picture of your situation from the start.

Can Parents Set Their Own Child Support Amount in Texas?

In many cases, parents can reach an agreement on child support rather than leaving it entirely to the court. A judge will generally approve a parent-agreed amount as long as it appears to be in the child's best interest. Some parents choose to deviate from the guidelines due to special circumstances, such as a child with significant medical needs or an arrangement in which both parents share time equally.

Whatever the parents decide, it has to go before a judge and become a formal court order. Informal or verbal agreements are not enforceable. The U.S. Census Bureau found that only 41 percent of custodial parents had any formal or informal child support agreement in place, meaning many parents raising children alone do not have a child support agreement that can be enforced through the court system. Parents sometimes assume a mutual understanding is enough to protect them, but it is not.

Does Texas Child Support Cover Health Insurance?

Child support in Texas covers more than a monthly payment. As part of the same child support order, the court will address the child's health insurance. One or both parents may be required to carry coverage if it is available at a reasonable cost through their employer. If neither parent has employer-sponsored coverage, the court can order a cash medical support payment instead. Dental and vision may also be included. The total child support obligation, cash payment plus medical support,  is what you should be thinking about when you are trying to understand what the order will actually cost you each month.
