Texas parents navigating divorce or custody proceedings need clear information about child support calculations. The state uses a percentage-based formula that many find confusing, particularly when determining what income counts and how deductions work. Understanding these calculations helps both custodial and non-custodial parents set realistic expectations and budget for their financial obligations.
Texas is one of the fastest-growing states in the nation, with over 30 million residents across diverse metropolitan areas and rural communities. As more families face separation and divorce, questions about child support calculations become increasingly common. The guidelines aim to provide consistent, fair support while accounting for Texas's wide range of income levels and family situations.
Key Takeaways for How Child Support Is Calculated in Texas
- Texas uses percentage guidelines based on the obligor's net monthly resources: 20% for one child, 25% for two children, 30% for three children, with increasing percentages for additional children.
- Net resources include nearly all income sources after specific deductions for Social Security taxes, federal income tax, union dues, and children's health insurance premiums—most other expenses cannot be deducted.
- The guideline cap increased to $11,700 in net monthly resources effective September 1, 2025, with courts having discretion about support on income exceeding this amount.
- Maximum guideline support under the new cap is $2,340 monthly for one child, $2,925 monthly for two children, and $3,510 monthly for three children, applying only to orders finalized on or after September 1, 2025.
- Courts may deviate from guidelines when applying them would be unjust or inappropriate, considering factors like possession time, special needs, and income disparity between parents.
Understanding Texas Child Support Guidelines
Texas Family Code Section 154.125 establishes percentage guidelines for calculating child support based on the paying parent's net resources. These percentages apply to net monthly resources up to $11,700 as of September 1, 2025. This cap applies to all new and modified support orders finalized on or after this date. Orders finalized before September 1, 2025, remain based on the previous $9,200 cap unless successfully modified.
The guidelines create presumptively correct support amounts. Courts must order guideline amounts unless parties agree to different amounts, the paying parent proves that applying guidelines would be unjust or inappropriate, or the child has special needs requiring different support levels. The party seeking deviation from the guidelines bears the burden of proving that the guidelines are inappropriate.
What Are Net Resources?
Net resources—the income amount used for support calculations—means something specific under Texas law. Texas Family Code Section 154.062 defines net resources as all income from all sources minus only specific allowed deductions.
Income Sources Included in Net Resources
Texas law counts nearly every income source when calculating net resources. In most cases, recurring income counts toward net resources. Income included in calculations encompasses:
- Wages, salary, and overtime pay
- Tips, gratuities, bonuses, and commissions
- Self-employment income and business profits
- Rental income from investment properties
- Interest, dividends, and royalty income
- Retirement and pension income
- Social Security benefits (excluding SSI)
- Disability and unemployment benefits
- Workers' compensation benefits
- Regular or recurring gifts may be included as income, depending on the facts
Certain limited exceptions exist. Courts exclude return of principal or capital, accounts receivable until actually received, and means-tested public assistance like SSI, SNAP, or TANF.
Allowed Deductions From Gross Income
Texas law permits only specific deductions when calculating net resources from gross income. Texas Family Code Section 154.062(b) lists the allowed deductions:
- Social Security taxes
- Federal income tax based on proper withholding allowances under IRS withholding schedules
- Union dues, if applicable
- Health insurance premiums paid for the children receiving support
These are the only permitted deductions. Texas has no state income tax, so no state tax deduction applies. Parents cannot deduct retirement contributions, 401(k) contributions, HSA contributions, child care costs, expenses for other children, credit card payments, or other financial obligations when calculating net resources.
This limited deduction list reflects legislative intent that child support receives priority over discretionary spending decisions. The law prioritizes the needs of children over the paying parent's other expenses and financial goals.
The Percentage Guidelines
Once net resources are calculated, Texas applies specific percentages based on the number of children before the court. The guideline percentages are:
- 20% for one child
- 25% for two children
- 30% for three children
- 35% for four children
- 40% for five children
- Not less than 40% for six or more children
These percentages apply to net monthly resources up to the $11,700 cap for orders finalized on or after September 1, 2025. Under the updated cap, maximum guideline support amounts are $2,340 monthly for one child, $2,925 monthly for two children, and $3,510 monthly for three children.
Step-by-Step Calculation Examples
Understanding how calculations work in practice helps parents anticipate support obligations and verify whether proposed amounts are accurate.
Example 1: Moderate Income, One Child
A father earns $5,000 monthly gross income as a W-2 employee. His deductions include $382.50 for Social Security and Medicare taxes. Federal income tax totals $500. Children's health insurance costs $150. Total deductions equal $1,032.50.
His net resources are $3,967.50 ($5,000 minus $1,032.50). Support for one child at 20% equals $793.50 monthly.
Example 2: Higher Income, Two Children
A mother earns $8,000 monthly gross income. Her deductions include $612 for Social Security and Medicare taxes. Federal income tax totals $900. Children's health insurance costs $200. Total deductions equal $1,712.
Her net resources are $6,288. Support for two children at 25% equals $1,572 monthly.
Example 3: Net Income Below the Cap
A father earns $15,000 monthly gross income. His deductions include $1,147.50 for Social Security and Medicare taxes. Federal income tax totals $2,200. Children's health insurance costs $300. Total deductions equal $3,647.50.
His net resources are $11,352.50. Because this falls below the $11,700 cap, the full amount is subject to guideline percentages. Support for three children at 30% equals $3,405.75 monthly.
Example 4: Income Exceeding the Cap
A mother earns $18,000 monthly gross income. After all allowed deductions, her net resources total $13,500. This exceeds the $11,700 cap. Guideline support on the cap for two children at 25% equals $2,925 monthly. Courts have discretion whether to order additional support on the $1,800 above the cap.
Self-Employment Income Calculations
Self-employed parents present calculation challenges because gross business receipts don't equal income available for support. Courts examine tax returns and financial statements to determine actual business income available for child support.
Analyzing Business Income
Courts typically review tax returns from the most recent one to three years. They also examine profit and loss statements. The process starts with identifying gross receipts. Courts then subtract legitimate business expenses.
Business Expense Review
Courts scrutinize self-employment expenses carefully. Legitimate business expenses include materials, supplies, equipment, employee wages, commercial rent, utilities, insurance, and necessary advertising. However, courts often disallow or limit certain claimed expenses.
Paper expenses like depreciation may be added back because they don't reduce actual cash available. Vehicle expenses for personal-use vehicles claimed as business vehicles face scrutiny. Excessive meals and entertainment may be limited. Partially personal travel expenses receive close examination. Inflated home office deductions often get reduced. Courts evaluate whether expenses are truly necessary for business operations or represent personal spending.
Income Above the Cap
For parents with net resources exceeding $11,700 monthly, courts first calculate guideline support on the capped amount. This represents the minimum support amount for high earners.
Courts then consider whether to order additional support based on above-cap income. This decision involves evaluating several factors specific to each family's circumstances.
Factors Courts Consider
Important factors include the children's proven needs and their standard of living before separation. Courts examine the paying parent's ability to pay additional support. The amount of possession time each parent has matters. Child care costs necessary for employment are considered.
Courts assess whether children have special needs that require additional support. Educational expenses factor into decisions. Other relevant circumstances affecting the children's best interests also matter.
High-income parents sometimes argue that guideline amounts on the cap already provide generously. Custodial parents counter with evidence of actual expenses like private school tuition, extracurricular activities, and enrichment programs.
Multiple Children With Different Parents
When paying parents have children with multiple partners, calculations become more complex. Courts in Texas are required to consider a parent's proven responsibilities for supporting other children when calculating child support, as mandated by Section 154.128 of the Texas Family Code.
When a parent already pays child support for children from prior relationships, courts may reduce the guideline percentage for subsequent children. Courts have discretion to adjust percentages. The goal is ensuring all children receive appropriate support while avoiding obligations that exceed the parent's ability to pay.
Possession Time and Support
Even with true 50-50 possession schedules, Texas courts typically don't eliminate child support. When parents have equal possession but income disparity exists, the higher earner typically pays support to the lower earner. The amount might be at reduced percentages from standard guidelines.
Health Insurance and Medical Support
Texas Family Code Section 154.182 requires courts to order parents to provide health insurance for children when available at a reasonable cost. "Reasonable cost" generally means insurance is available through employers at subsidized group rates.
Medical Support Orders
Beyond insurance, courts establish medical support addressing uninsured medical expenses. These include copays, deductibles, prescriptions, and expenses for uncovered services. Typically, parents split uninsured medical costs on a percentage basis. This percentage reflects their relative incomes.
When parents pay children's health insurance premiums, Section 154.062 allows the deduction of those premiums from gross income. This prevents double-counting. Parents shouldn't have to pay for insurance and have that expense reflected in the net resources used to calculate support.
When Courts Deviate From Guidelines
Texas Family Code Section 154.123 lists factors courts may consider when determining whether guidelines would be unjust or inappropriate. Common factors that may support guideline deviations include:
- Age and needs of the children
- Ability of parents to contribute to support
- Amount of possession time each parent has
- Childcare costs necessary for employment
- Extraordinary medical expenses
- Travel expenses for possession and access
- Whether either parent provides health insurance
- Educational expenses beyond typical costs
- Other relevant factors affecting the children's best interests
Courts have broad discretion to deviate based on these factors. However, they must make specific findings. These findings must explain why guidelines are inappropriate and why the ordered amount serves the best interest of the children.
Modification of Child Support Orders
Support orders may be modified when circumstances materially and substantially change. Texas Family Code Section 156.401 creates presumptions about when modification is warranted.
Courts presume modification is appropriate if applying current guidelines to current circumstances would vary from existing support by $100 monthly or 20%, whichever is greater. Common modification circumstances include significant changes in income resulting from job loss or promotions. Children's changing needs provide grounds for modification. Possession schedule changes may also justify modifications.
Support doesn't automatically change when circumstances change. Parents must file modification petitions and obtain court orders. Parents who experience income changes but don't seek modification continue owing the original amounts. Unpaid support accumulates as arrears.
FAQ for Calculation of Child Support in Texas
What Is the Difference Between Gross Income and Net Resources?
Gross income includes all wages and earnings before any deductions. Net resources are what remain after subtracting only specific allowed deductions. These include Social Security taxes, federal income tax, union dues, and children's health insurance premiums. Most other deductions, like retirement contributions or debt payments, cannot be subtracted when calculating net resources.
Do Bonuses and Overtime Count Toward Child Support?
Yes. Texas law includes bonuses, overtime pay, commissions, and other variable income when calculating net resources. Courts may average bonuses over multiple years for parents who receive irregular annual bonuses. Alternatively, courts may annualize bonuses and include monthly portions in net resources calculations.
Can Judges Order More Than the Guideline Percentages?
Yes, but only after making specific findings that guidelines would be unjust or inappropriate under the circumstances. Courts consider factors like children's special needs and extraordinary expenses. Substantial income disparity between parents matters. Other circumstances affecting children's best interests are evaluated when deciding whether to deviate from guidelines.
What Happens If I'm Self-Employed?
Courts examine your tax returns from recent years along with profit and loss statements. They determine the actual business income available for support. Legitimate business expenses are subtracted. However, courts scrutinize expenses carefully. They ensure expenses are necessary business costs rather than personal expenses run through the business.
