Child Support Calculator Texas 2026: How Payments Work

If you are going through a divorce or separation in Texas and have children, understanding how child support is calculated is essential for planning your finances. Texas uses a relatively straightforward percentage-of-income model that differs significantly from the income shares approach used by most other states. In this guide, we will break down exactly how the Texas child support formula works in 2026, walk through the income guidelines and caps, provide real calculation examples, and explain the filing process step by step.

How Texas Child Support Works: The Percentage Model

Unlike the 40+ states that use the Income Shares Model (which considers both parents' incomes), Texas uses the Percentage of Income Model. This means the child support calculation looks primarily at the non-custodial parent's income. The custodial parent's income is generally not factored into the basic guideline calculation.

The Texas Family Code, Section 154.125, establishes the following guideline percentages based on the number of children before the court:

1 child: 20% of net resources
2 children: 25% of net resources
3 children: 30% of net resources
4 children: 35% of net resources
5 children: 40% of net resources
6+ children: Not less than the amount for 5 children

These percentages apply to the obligor's (non-custodial parent's) net resources, which is gross income minus certain deductions. This is a critical distinction — the percentages apply to net, not gross, income.

What Counts as “Net Resources” in Texas?

Texas defines “net resources” broadly. The calculation starts with all income from all sources and then subtracts specific deductions.

Income Sources Included

Wages, salary, overtime, bonuses, and commissions
Self-employment income (net of reasonable business expenses)
Interest, dividends, and royalty income
Rental income
Trust income and annuities
Social Security benefits (except Supplemental Security Income)
Unemployment benefits
Workers' compensation benefits
Retirement and pension income
Military pay, including allowances
Severance pay
Capital gains

Allowable Deductions

Federal income taxes (based on single filing status, one exemption)
State income taxes (not applicable in Texas, but relevant if earning income in another state)
Social Security taxes (FICA)
Union dues
Health insurance premiums for the child
Dental insurance premiums for the child
Mandatory retirement contributions (not voluntary 401(k) deferrals)

Important: Voluntary deductions like 401(k) contributions, IRA contributions, and elective insurance premiums for the obligor only are generally not subtracted from net resources. Courts look at what you could have available, not what you choose to set aside.

The 2026 Texas Income Cap

Texas sets a cap on the amount of net resources subject to the guideline percentages. For 2026, the cap on net resources is $9,200 per month (approximately $110,400 per year in net resources). This means that regardless of how much the obligor earns, the guideline child support for one child maxes out at 20% of $9,200 = $1,840 per month.

If the obligor's net resources exceed the cap, the court can order additional support above the guideline amount, but the custodial parent must prove that the child's “proven needs” require it. This typically involves documenting expenses such as private school tuition, special medical needs, extracurricular activities, and the child's historical standard of living.

Step-by-Step: How to Calculate Texas Child Support

Let us walk through a detailed example. Assume the non-custodial parent (obligor) earns a gross monthly salary of $7,500, has one child, and provides health insurance for the child at $200/month.

Step 1: Determine Gross Monthly Income

Gross monthly income: $7,500

Step 2: Calculate Deductions

Federal income tax (est.): $850
Social Security tax (6.2%): $465
Medicare tax (1.45%): $108.75
Child's health insurance: $200
Total deductions: $1,623.75

Step 3: Calculate Net Resources

$7,500 − $1,623.75 = $5,876.25 net resources per month

Step 4: Apply the Guideline Percentage

For one child, the guideline is 20%: $5,876.25 × 0.20 = $1,175.25 per month

This $1,175.25 is the guideline child support amount. The court may adjust this figure based on specific circumstances, but this is the starting point for any negotiation or court order.

Multiple Families: The “Other Children” Adjustment

If the obligor has children from another relationship (not before the current court), Texas adjusts the guideline percentages downward. This is called the “multiple family” adjustment under Family Code Section 154.129.

For example, if the obligor has one child before the court and one other child from a different relationship, the guideline for the child before the court drops from 20% to 17.5%. The adjustments are specified in a detailed table in the Texas Family Code. The principle is that each child the obligor supports reduces the percentage allocated to any single child, recognizing that the obligor's resources must be spread across multiple dependents.

Income Ranges and Expected Payments

Here is what guideline child support looks like across different income levels for one child in Texas (2026):

$3,000/month gross (~$2,400 net): ~$480/month
$5,000/month gross (~$3,900 net): ~$780/month
$7,500/month gross (~$5,875 net): ~$1,175/month
$10,000/month gross (~$7,600 net): ~$1,520/month
$12,000/month gross (~$9,200+ net): ~$1,840/month (cap)

Note: These are estimates. Actual net resources depend on specific deductions including federal tax withholding, which varies based on filing status and other factors.

When Courts Deviate from the Guidelines

Texas courts can order child support above or below the guideline amount if the circumstances warrant it. Factors the court considers include:

The child's age and specific needs (medical, educational, developmental)
Childcare expenses necessary for the custodial parent to work
The child's pre-separation standard of living
Each parent's ability to contribute to the child's needs
Travel costs for visitation if parents live far apart
Positive or negative cash flow from assets or debts
Benefits the obligor receives from employment (company car, housing, etc.)
The cost of health and dental insurance for the child

The court must specifically state in its order why it is deviating from the guidelines. Deviations are most common in high-income cases above the cap and in cases involving children with special needs.

How to File for Child Support in Texas

If you need to establish a child support order in Texas, here is the process:

Option 1: Through the Office of the Attorney General (OAG)

The Texas OAG Child Support Division provides free services to establish, modify, and enforce child support orders. You can apply online at the OAG website. The OAG will locate the other parent if needed, establish paternity if necessary, and file the case with the court. Processing typically takes 4-6 months from application to court order.

Option 2: Through a Private Attorney

Hiring a family law attorney gives you more control over the process and is recommended for complex situations (high income, contested custody, self-employment, interstate issues). Expect to pay $200-$400 per hour, with total costs of $2,000-$10,000 depending on complexity.

Option 3: Through Divorce Proceedings

If you are going through a divorce, child support is determined as part of the divorce case. Your divorce attorney will address child support, custody, and property division in a single proceeding.

Enforcement: What Happens If Payments Are Missed?

Texas takes child support enforcement seriously. Consequences for non-payment include:

Wage withholding (automatic in most cases)
Interception of tax refunds and lottery winnings
Suspension of driver's license, professional licenses, and hunting/fishing licenses
Negative credit reporting
Liens on property and bank accounts
Contempt of court charges (up to 6 months in jail per violation)
Passport denial if arrears exceed $2,500

Modifying a Texas Child Support Order

Either parent can petition to modify child support if there has been a material and substantial change in circumstances since the last order, or if it has been three or more years since the order was established or modified and the current order differs by 20% or $100 from the guideline amount based on current circumstances. Common reasons for modification include job loss or significant income change, changes in the child's needs, changes in custody or visitation time, and the child's emancipation or aging out of the order.

Medical Support in Texas

In addition to cash child support, Texas courts order one or both parents to provide health insurance for the child. If private insurance is not available at a reasonable cost (generally defined as no more than 9% of the obligor's gross income), the court may order cash medical support instead. The court also typically orders both parents to share unreimbursed medical expenses proportionally.
