How Is Child Support Calculated in Texas?

When parents separate or divorce, child support is among the most practically important and most frequently disputed financial issues they will face. The amount of support can significantly affect both households — the custodial parent’s ability to meet the child’s daily needs, and the obligor’s ability to manage their own financial obligations. Texas law provides a guideline formula that governs how child support is calculated in most cases, but the formula involves more variables and more potential for dispute than many parents initially expect.

Understanding how the Texas guideline formula works — what income is included, what deductions are allowed, how the statutory cap operates, and when courts can deviate from the guidelines — gives parents a realistic foundation for evaluating their situation and making informed decisions about negotiation, modification, and enforcement.

Cuccia Wilson, PLLC represents parents in child support matters in Dallas, Cleburne, and across North Texas. Michael Wilson handles family law from the firm’s Cleburne office. Below, we explain the Texas child support calculation framework under Chapter 154 of the Texas Family Code, the statutory income cap, deviation factors, shared custody considerations, duration of the obligation, and enforcement mechanisms.

The Texas Child Support Guideline Formula

Texas child support is governed by Chapter 154 of the Texas Family Code. The guideline formula calculates support based on the obligor’s net monthly resources and the number of children being supported. The standard guideline percentages are:

Number of Children Supported	Guideline Percentage of Net Resources	Example: $5,000 Net Monthly Resources
1 child	20%	$1,000 per month
2 children	25%	$1,250 per month
3 children	30%	$1,500 per month
4 children	35%	$1,750 per month
5 or more children	40% (minimum)	$2,000 per month (minimum)

These percentages apply to the obligor’s net resources up to the statutory income cap. When the obligor has children from multiple relationships, the percentages are adjusted under Texas Family Code § 154.128 to account for support obligations to other children.

What Counts as Net Resources Under Texas Law?

Calculating the obligor’s net resources is the first and often most contested step in the child support calculation. Texas Family Code § 154.062 defines net resources as gross income from all sources minus specific allowable deductions.

Income That Is Included

• Wages, salary, and hourly pay (including overtime)
• Self-employment income (gross receipts minus ordinary and necessary business expenses)
• Tips, bonuses, and commissions
• Rental income from real and personal property
• Interest, dividends, and investment income
• Royalties and licensing fees
• Trust distributions and annuity income
• Social Security retirement and disability benefits
• Unemployment compensation and workers’ compensation benefits
• Veterans’ benefits
• Net income from partnerships and S corporations

Allowable Deductions From Gross Income

• Federal income taxes (based on the obligor’s filing status and withholding)
• Social Security taxes (FICA)
• Medicare taxes
• State and local income taxes
• Union dues, if applicable
• Cost of health insurance or health maintenance organization premiums paid for the child

After these deductions are applied, the remaining figure is the obligor’s net monthly resources for child support purposes. Note that personal expenses, voluntary retirement contributions, and most other deductions not listed above are not subtracted when calculating net resources.

The Statutory Income Cap and High-Income Cases

Texas Family Code § 154.125 establishes a cap on the net resources used in the guideline calculation. For 2024, the cap is $9,200 per month in net resources. When an obligor’s net monthly resources are at or below the cap, the standard guideline percentages apply directly. When net monthly resources exceed the cap, the guideline percentages are applied only to the first $9,200, producing the presumptive minimum guideline amount.

In cases where the obligor’s income significantly exceeds the cap, the court may order additional support above the minimum guideline amount if evidence establishes that the child’s proven needs justify a higher figure. The obligee (receiving parent) bears the burden of presenting evidence of the child’s actual needs in excess of what the minimum guideline amount would cover. Courts are not required to award additional support in high-income cases — the decision is discretionary and evidence-dependent.

Imputed Income: When the Court Looks Beyond Actual Earnings

Texas courts are not required to accept an obligor’s stated income at face value. Under Texas Family Code § 154.066, if the court finds that an obligor is intentionally unemployed or underemployed — earning less than they are capable of earning given their education, skills, and work history — it may impute income at the level the obligor has the earning capacity to achieve and calculate child support on that basis.

Imputation of income is a significant litigation issue in many child support cases. Common scenarios include: a parent who voluntarily leaves a higher-paying job to reduce their support obligation; a self-employed parent who underreports income by characterizing personal expenses as business deductions; a parent who takes an extended period of voluntary unemployment; and a parent who accepts a position far below their demonstrated earning capacity without justification. The court considers the parent’s work history, education and credentials, the job market in the area, and other relevant factors in determining what income should be imputed.

When Courts Deviate From the Child Support Guidelines

The guideline amount is presumed appropriate, but Texas Family Code § 154.123 allows courts to order a different amount when the evidence establishes that the guideline amount would be unjust or inappropriate. The court must make written findings explaining the deviation. Factors that may justify ordering more or less than the guideline amount include:

• The age, physical condition, educational needs, and actual expenses of the child
• Whether either parent is responsible for other children, including children not covered by the current order
• The amount of time the obligor spends with the child and any related travel and transportation costs
• Significant debt obligations of the obligor, particularly those incurred for the benefit of the child or family
• Whether the obligee provides substantial benefits to the child in kind (such as free housing in a family property)
• Special educational needs, healthcare expenses, or other documented extraordinary expenses for the child
• Any other relevant factor that the court determines is in the best interest of the child

Modifying a Texas Child Support Order

A child support order is not necessarily permanent. Under Texas Family Code § 156.401, modification is available when either of two conditions is met:

• There has been a material and substantial change in the circumstances of the child or a person affected by the order since it was entered — examples include a significant change in the obligor’s income, job loss, a substantial change in the child’s medical or educational needs, or a change in custody arrangements
• It has been three years or more since the order was established or last modified, and the amount of child support ordered differs by either 20% or $100 per month from the amount that would be awarded under the current guidelines

The three-year / 20% or $100 rule provides an alternative path to modification that does not require proving a material and substantial change — the passage of time and the difference from current guidelines is itself sufficient. Parents who believe their support obligation has become significantly out of line with current guidelines should have the amount reviewed rather than making informal adjustments, as unilateral reductions in child support payments are not legally recognized and can result in enforcement actions for the full ordered amount.

Frequently Asked Questions: Child Support in Texas

How is child support calculated in Texas?

Texas child support is calculated under a statutory guideline formula established in Texas Family Code Chapter 154. The formula begins with the obligor’s (paying parent’s) net monthly resources, which are determined by taking gross income from all sources and subtracting specific allowable deductions including federal income tax, Social Security taxes, Medicare taxes, union dues if applicable, and the cost of health insurance coverage for the child. The resulting net resources figure is then multiplied by a percentage that increases with the number of children being supported: 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more. These percentages are applied up to the statutory income cap — for 2024, $9,200 per month in net resources. If the obligor’s net resources exceed the cap, the court may order additional support above the guideline amount if the child’s proven needs justify it, but is not required to do so. The guideline amount is presumed to be in the best interest of the child, and courts may deviate from it only when specific statutory factors justify a different amount.

What counts as income for Texas child support purposes?

Texas Family Code § 154.062 defines net resources broadly to include virtually all forms of income and financial benefit received by the obligor. Income that counts includes: wages, salary, and hourly pay; self-employment income (gross receipts minus ordinary and necessary business expenses); tips, overtime, and shift differentials; bonuses and commissions; rental income from real and personal property; royalties and licensing fees; interest, dividends, and investment income; trust and annuity income; Social Security retirement and disability benefits; veterans’ benefits; unemployment compensation; workers’ compensation benefits; and net income from partnerships and S corporations. The court also considers whether an obligor is intentionally unemployed or underemployed. If the court finds that a parent is earning less than they are capable of earning — by voluntarily reducing income, taking a lower-paying position without justification, or refusing to seek employment consistent with their skills and experience — it may impute income at the level the parent has the capacity to earn and base child support on that imputed amount rather than actual earnings.

What is the Texas statutory income cap for child support, and how does it work?

Texas Family Code § 154.125 establishes a statutory cap on the net resources used in the guideline child support calculation. The cap is adjusted periodically and for 2024 stands at $9,200 per month in net resources. When a parent’s net monthly resources are at or below the cap, the standard guideline percentages apply directly to the full net resources figure. When net monthly resources exceed the cap, the standard guideline percentages are applied only to the first $9,200 — producing the minimum guideline amount. If the obligor’s income significantly exceeds the cap, the court may order additional child support above the minimum guideline amount if evidence demonstrates that the child’s proven needs justify a higher amount. The court is not required to award additional support in high-income cases, but it has the discretion to do so when the evidence supports it. This means that in high-income cases, child support is not automatically a simple percentage of the obligor’s total earnings — it requires a separate evidentiary showing about the child’s actual needs.

Can a Texas court deviate from the child support guidelines?

Yes. Texas Family Code § 154.123 permits courts to order child support in an amount different from the guideline amount when the evidence establishes that the guideline amount would be unjust or inappropriate. The court must make specific written findings explaining why the guideline amount was not followed. Factors that may justify deviation include: the age, educational requirements, physical conditions, and actual needs of the child; whether either parent has custody of other children; the amount of time the obligor spends with the child and any related travel costs; significant debt obligations of the obligor; whether one parent provides substantial in-kind contributions such as housing; special educational or healthcare expenses not covered by insurance; and any other factor the court considers relevant to the best interest of the child. In shared custody arrangements where each parent has the child for a substantial portion of time, courts may also apply an extended possession offset, which adjusts the guideline amount downward to reflect the costs the obligor bears during their own possession time.

How does shared custody affect child support in Texas?

Shared or equal custody does not automatically eliminate child support in Texas. The guideline formula is based primarily on the obligor’s net resources and the number of children — not on the possession schedule. Even when both parents share custody on an approximately equal basis, a court will still typically calculate guideline support and consider whether an adjustment is appropriate based on the extended possession offset. The extended possession offset under Texas Family Code § 154.123 may reduce the guideline amount when the obligor exercises substantially more than the standard possession schedule — particularly in true 50/50 arrangements. However, if one parent earns significantly more than the other, some level of child support is likely to remain even in a truly equal possession arrangement, because the goal is to equalize the standard of living the child experiences in each household to the extent possible. Parents who reach private agreements about child support in shared custody situations should have those agreements reviewed by an attorney and incorporated into a court order, because informal arrangements are not enforceable.

How long does child support last in Texas, and what ends the obligation?

Under Texas Family Code § 154.001, the obligation to pay child support in Texas generally continues until the earliest of the following: the child turns 18 years of age; the child graduates from high school (if the child is enrolled and attending when they turn 18, support continues through graduation or until the end of the school year in which the child turns 19, whichever comes first); the child marries; the child’s disabilities are removed by court order (emancipation); the child dies; or a court order specifically terminating the obligation earlier. For a child with disabilities that substantially limit their ability to live independently and support themselves, child support may continue beyond age 18 upon request. The termination of child support does not happen automatically by operation of law in all cases — to stop wage withholding or other enforcement mechanisms, a formal termination process through the court or the Texas Attorney General’s Child Support Division may be required. Obligors who stop paying based on their belief that the obligation has ended without obtaining formal confirmation risk accumulating arrears that are enforceable even after the child reaches adulthood.

What enforcement tools does Texas use when child support is not paid?

Texas law provides extensive enforcement mechanisms for child support orders, administered through both courts and the Texas Attorney General’s Child Support Division. Income withholding — automatic deduction of child support from the obligor’s paycheck — is required in virtually all new child support orders and is the most common enforcement mechanism. When an obligor falls behind in payments, additional enforcement tools may include: interception of federal and state tax refunds; suspension of the obligor’s driver’s license, professional licenses, recreational licenses, and passport; filing of a lien against the obligor’s real and personal property; reporting of delinquencies to credit bureaus; civil contempt proceedings in district court, which can result in fines and jail time; and referral to the Texas Attorney General’s Office for criminal prosecution under Texas Penal Code § 25.05 (criminal nonsupport), which is a state jail felony when the obligor intentionally or knowingly fails to provide support and the child is in danger of going without necessities. Arrears in Texas child support do not expire and continue to accrue interest at the rate of 6% per year.
