Key Takeaways

  • Texas child support laws, governed by the Texas Family Code Chapter 154, establish guidelines to ensure children receive necessary financial support from both parents.
  • When calculating child support, all sources of income are considered, and allowable deductions from gross income help determine net resources crucial for support calculations.
  • Recent updates to the income cap for child support calculations set a new threshold of $11,700 to reflect rising costs, influencing financial obligations for higher earners.

Understanding Texas Child Support Laws

Texas child support laws were created to ensure that every child receives consistent financial support from both parents, regardless of changes in their family structure. The foundation of these laws is found in Texas Family Code Chapter 154, which governs how support is calculated, enforced, and modified. The process of Texas Child Support Calculation Based on Income uses a parent’s net resources—not their gross pay—to determine fair contributions. This approach ensures that the child’s best interests remain at the heart of every order, balancing financial responsibility with practical realities faced by both parents.

Under Texas Family Code §154.125(a-1), the state recently increased the income cap for guideline calculations from $9,200 to $11,700 per month effective September 1, 2025. This update reflects rising living costs and helps ensure that child support amounts better meet children’s actual needs. Guideline percentages—20% for one child, 25% for two, 30% for three, and so on—are applied to the paying parent’s net monthly resources. For a deeper understanding of how these resources are defined and calculated, explore our comprehensive guide on Net Resources in Texas.

Under §154.062 of the Texas Family Code, courts consider multiple income sources such as wages, commissions, bonuses, and self-employment earnings when determining child support. From that total, deductions like taxes, union dues, and the child’s health insurance premiums are subtracted to find the true “net” amount. These detailed provisions create a transparent framework designed to ensure fairness, prevent disputes, and protect the financial well-being of the child.

Navigating child support can feel overwhelming, but guidance from an experienced Texas family law attorney makes all the difference. The legal team at The Law Office of Bryan Fagan, PLLC, provides personalized strategies to ensure your child support order is accurate, enforceable, and fair.

What Counts as Income for Child Support Calculations?

When calculating child support in Texas, various types of income are considered, including wages, bonuses, and self-employment income. Monthly gross income is calculated before any deductions are applied, ensuring that all sources of income are accounted for. Self-employed parents must report a variety of income sources, such as salary, commissions, bonuses, and rental income, to ensure accurate child support calculations.

Texas courts determine child support payments based on a parent’s net income, as outlined in the Texas Family Code and the texas child support guidelines. This comprehensive approach ensures that all financial resources are considered, providing a fair basis for calculating child support obligations.

Understanding what counts as income is crucial for one or both parents, as it directly impacts the amount of support owed and received.

Determining Net Resources for Child Support

Determining net resources for child support calculations involves several steps, including deducting allowable expenses from gross income. These certain deductions include:

  • Business expenses
  • OASDI (Old-Age, Survivors, and Disability Insurance)
  • Medicare
  • Federal taxes
  • Union dues
  • Health insurance premiums These deductions are subtracted from gross income to determine net resources.

The monthly amount for state income taxes should be entered if applicable. When calculating net resources for child support, the following are deducted:

  • Social security taxes
  • Federal income tax
  • State income tax
  • Union dues
  • Health insurance
  • Social security tax

Accurately determining net resources ensures that Texas courts’ child support calculations are fair and reflective of the parent’s true financial situation.

Net monthly income for child support is calculated by dividing yearly income by 12 and subtracting taxes, union dues, and medical support. This comprehensive child support calculation includes income from wages, salaries, commissions, bonuses, and self-employment, minus taxes and health insurance to determine monthly net resources. Both parents need to understand this process for calculating child support payments and the child support payment obligations to ensure that a child support calculator is used to accurately assess and enforce child support obligations. Additionally, it is important to know how to calculate child support effectively.

Texas Child Support Percentages Based on Number of Children

When it comes to Texas Child Support Calculation Based on Income, the law provides clear and structured guidelines designed to ensure children receive fair and consistent financial support from both parents. Under Texas Family Code §154.125, child support is calculated as a percentage of the noncustodial parent’s net monthly resources, with the percentage increasing based on the number of children covered by the order. Generally, the state’s guidelines allocate 20% of net income for one child, 25% for two, 30% for three, 35% for four, and up to 40% for five or more children. This system reflects the principle that as the number of children increases, so does the financial responsibility required to support their well-being.

Effective September 1, 2025, the Texas Legislature updated the income cap that applies to these calculations, raising it from $9,200 to $11,700 per month. This adjustment, outlined in Texas Family Code §154.125(a-1), recognizes the impact of inflation and the rising cost of raising children. However, for parents whose income exceeds that amount, the court may order additional support if the child’s proven needs justify it. Understanding how this cap functions is especially important for high-income parents navigating complex financial situations, as discussed in the firm’s in-depth resource on How the Texas Child Support Cap Works for High-Income Parents.

While these guideline percentages form the foundation of most child support orders, courts have discretion to deviate when unique circumstances arise—such as special medical needs, educational expenses, or extraordinary extracurricular costs. In those situations, judges rely on Texas Family Code §154.123, which allows for adjustments to ensure the final order truly serves the child’s best interest. Knowing how these statutes interact can help parents plan ahead, avoid misunderstandings, and ensure compliance with court expectations.

For families seeking clarity on how their income, number of children, or unique financial factors might influence support obligations, working with an experienced Texas family law attorney is essential. The compassionate legal team at The Law Office of Bryan Fagan, PLLC, has guided countless parents through every stage of the child support process—from calculation to modification and enforcement. To learn more about how Texas courts approach these cases, explore our Texas Child Support Resources. With the right legal guidance, you can protect your rights, meet your obligations, and build a stable foundation for your family’s future.

The Income Cap on Net Resources for Texas Child Support

Starting September 1, 2025, the income cap for calculating child support in Texas will rise from $9,200 to $11,700, reflecting inflation and rising costs for child-related expenses. For parents exceeding the new cap of $11,700, only the first $11,700 of their income is considered for child support calculations. This change aims to balance the financial burden on high earners while ensuring that children’s needs are met, raising questions about how much child support will be required.

High earners might be oblivious to the guideline cap. As a result, they could end up paying several thousand dollars extra each month beyond what is legally necessary. The income cap on net resources determines the maximum income considered for Texas child support calculations, ensuring that support obligations are fair and proportionate to the parent’s financial capability.

This cap helps parents avoid child support and ensures that child support payments align with legal requirements.

Factors Affecting Child Support Calculations

When determining Texas Child Support Calculation Based on Income, courts look beyond simple percentages to ensure every order reflects the real circumstances of the family. While the foundation for these calculations comes from Texas Family Code Chapter 154, judges have discretion to adjust support based on shared custody arrangements, medical needs, or other family obligations. This approach ensures that child support remains fair, practical, and focused on the child’s best interests.

Shared custody can have a meaningful impact on how child support is determined. When both parents share significant parenting time, courts may credit the noncustodial parent for expenses like food, housing, and extracurricular activities. Similarly, under Texas Family Code §154.128, if a parent has additional children from another relationship, those obligations may reduce the amount owed, as Texas law seeks to balance a parent’s duty among all dependents fairly.

Courts may also adjust child support for extraordinary circumstances, such as a child’s medical or educational needs. Under Texas Family Code §154.123, judges can deviate from the standard percentages to account for unique factors like special therapies, tutoring, or high travel costs for visitation. These provisions give courts the flexibility to tailor orders to meet each child’s specific needs while maintaining fairness between parents.

The 2025 update to Texas Family Code §154.125(a-1) increased the income cap for support calculations from $9,200 to $11,700, aligning with modern living costs and providing more accurate support for families. To understand how these new limits and percentages work, visit the firm’s in-depth guide on the New Texas Child Support Guideline Cap and Percentages 2025 Update. The compassionate attorneys at The Law Office of Bryan Fagan, PLLC, continue to help parents navigate these updates with clarity and confidence, ensuring every child receives the support they deserve.

Factors affecting child support calculations in Texas.

Requesting a Modification of Child Support Payments

Requesting a modification of child support payments due to income changes involves a formal process under Texas Family Code §156.401. A modification request can be based on material and substantial changes in circumstances since the last order. If the current amount differs from the guideline amount by 20% or $100 after three years, the court may alter child support orders.

Accurate documentation, such as pay stubs and tax returns, supports the request for modifying child support payments. Changes in income or expenses should meet the legal standard for a ‘material change in circumstances’ to qualify for a modification. The court must consider if the modification is in the child’s best interest when deciding on changes to support orders.

Key points regarding modification of child support obligations due to incarceration:

  • Incarceration of a child support obligor for over six months qualifies as a substantial change for modifying support obligations.
  • Parents with existing child support orders must formally request a modification to reflect the new cap.
  • Following this process ensures that child support payments accurately reflect the current financial situation.

Checklist for Verifying Child Support Calculations

Verifying child support calculations involves several crucial steps to ensure accuracy and compliance with legal requirements. First, confirm legal obligations to order child support by reviewing court orders and administrative orders. Thorough and organized documentation of financial records is essential for strengthening a child support case.

Maintaining records of interactions with the other parent helps build a stronger case. Following this checklist helps parents ensure their child support calculations are accurate and reflective of their financial obligations. This proactive approach helps avoid disputes and ensures that children receive the support they need.

Common Mistakes in Calculating Child Support

Common mistakes in calculating child support can lead to significant financial discrepancies and legal complications. One frequent error is failing to verify actual child support payments through documents such as:

  • Canceled checks
  • Wage withholding statements
  • Records from the Attorney General Providing proof of payments is crucial, and this can be substantiated by statements from the custodial parent regarding direct payments.

Another common mistake is miscalculating the amount owed by not accounting for all sources of income or allowable deductions. Accurately reporting and verifying all financial details helps avoid these mistakes. By being vigilant and thorough, parents can prevent errors that could lead to overpayment or underpayment of child support.

Tips for Managing Child Support Orders After Income Changes

When it comes to Texas Child Support Calculation Based on Income, life doesn’t always stay the same—especially when it comes to finances. A sudden job loss, promotion, or change in self-employment income can quickly make an existing child support order outdated. Under Texas Family Code §156.401, either parent has the right to request a modification when there has been a “material and substantial change” in circumstances, such as a significant increase or decrease in income. Acting promptly protects both parents from falling behind and ensures the child’s needs continue to be met without interruption.

If your income changes—whether up or down—it’s important to request a modification rather than simply adjusting payments on your own. Texas courts rely on verified financial information to ensure fairness, and formal modification keeps you in compliance with the law. The goal of every modification is to align payments with your current financial reality while maintaining the child’s financial stability. The focus remains on what matters most: ensuring that your child continues to have the resources they need to thrive.

Under the updated Texas Family Code §154.125(a-1), effective September 1, 2025, the maximum monthly net resources used for guideline calculations increased to $11,700. This change means that both income increases and decreases can have a more meaningful impact on child support amounts than in previous years. For parents wondering how these changes affect real-life numbers, the firm’s resource on What Is the Average Child Support for One Child in Texas provides helpful examples and legal insight into current guideline expectations.

Frequently Asked Questions

How to calculate net income for child support in Texas?

Texas calculates child support based on “net resources,” not gross pay. That means you start with all income sources—wages, bonuses, overtime, self-employment, rental income, and more—then subtract approved deductions like federal income tax, Social Security (OASDI), Medicare, union dues, and the child’s health insurance or cash medical support. The court then applies a percentage (20% for one child, 25% for two, and so on) to the resulting monthly net resources as outlined in Texas Family Code §§154.061–154.063.

What is the biggest factor in calculating child support?

The biggest factor is the paying parent’s monthly net resources. Texas Family Code §154.125 outlines how much of that income goes toward child support depending on how many children are included in the order. The court can adjust the guideline amount if special circumstances—like medical needs or extraordinary expenses—make it necessary.

Does Texas have a child support calculator?

Yes. The Texas Office of the Attorney General offers an online child support calculator that estimates monthly payments based on income and number of children. It’s a great starting point, but real cases can vary when bonuses, self-employment, or additional financial factors are involved, so it’s best to confirm with an attorney before relying on the estimate.

How does the Texas court determine child support?

Texas courts verify income, apply allowable deductions, and calculate monthly net resources. Then, they apply guideline percentages based on how many children are before the court—capped at a maximum monthly net income of $11,700 as of September 1, 2025. Judges can order more or less support if the situation calls for it, particularly when a child has unique needs.

How much do most dads pay in child support in Texas?

There’s no fixed amount, since every case depends on the parent’s income and the number of children. The guideline percentages are 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more. These percentages apply up to the statutory cap, and the court may adjust the amount if special circumstances apply.

Can my ex go after my new wife’s income?

Generally, no. Texas law considers only the parent’s own income when calculating child support. A new spouse’s earnings are separate and aren’t used in support calculations. However, if a parent is intentionally underemployed or receiving significant financial help from a new spouse, the court may consider those circumstances when evaluating fairness or intent.

What looks bad in a custody case?

Courts prioritize a child’s stability and best interests. Behaviors that hurt your credibility or show poor judgment—like missed visitations, negative talk about the other parent, exposing children to unsafe conditions, failing to pay child support, or ignoring court orders—can negatively affect custody outcomes. Consistency, cooperation, and respect for boundaries go a long way.

What is the minimum a father has to pay for child support?

There’s no universal minimum, but Texas courts typically base it on at least minimum wage if a parent is unemployed or underemployed. The court can impute income based on earning potential. In very limited cases—such as disability or incarceration—child support may be temporarily lowered, though health insurance obligations still apply.

What is the most money child support can take?

As of September 1, 2025, the guideline cap for monthly net resources is $11,700. Applying the standard percentages, the maximum guideline amounts are about $2,340 for one child, $2,925 for two, $3,510 for three, $4,095 for four, and $4,680 for five or more children. Courts can order more if the child’s proven needs justify it, especially in high-income cases.

Instructions & Forms: Revising Texas Child Support Calculation Based on Income

When your financial situation changes, your child support order should change with it. Texas law recognizes that job loss, promotions, medical expenses, and new family responsibilities can all affect your ability to meet support obligations. Use the steps below to revise your Texas Child Support Calculation Based on Income in compliance with the Texas Family Code.


Step 1: Confirm Eligibility for Modification

You can request a modification of your existing child support order if one of the following applies:

  • There has been a material and substantial change in circumstances since your last order (e.g., job loss, significant pay increase, changes in childcare or health insurance costs, or custody changes).
  • Your order is more than three years old, and the new calculation under state guidelines would differ by 20% or $100 from your current payment amount.

Relevant law: Texas Family Code §154.125 (Guidelines) and Texas Family Code §156.401 (Modification).

Step 2: Gather Financial and Supporting Documents

Accurate documentation helps the court fairly recalculate support using your current net resources.

  • Three most recent pay stubs or income statements
  • Most recent federal income tax return (Form 1040) and W-2s/1099s
  • Proof of health and dental insurance premiums paid for the child(ren)
  • Childcare, medical, or therapy invoices and receipts
  • Proof of income change (termination letter, offer letter, unemployment statement)
  • Documentation of new dependents or household changes (if applicable)

Need a quick prep guide? Review our checklist: Texas Child Support Documentation Checklist.

Step 3: Complete the Required Forms

Prepare and file the following in the county where your current order was issued:

  1. Petition to Modify the Parent–Child Relationship — explains the change requested and the legal basis.
  2. Financial Information Statement — details income, deductions, and expenses per Texas Family Code §154.062 (Net Resources).
  3. Proposed Order Modifying Parent–Child Relationship — the judge-signed order that replaces the old support terms.
  4. Waiver of Service (optional) — if the other parent agrees, this can avoid formal service.

Tip: When both parents agree, an Agreed Modification Order can often be finalized more quickly. Our team can draft compliant agreed orders for signature and submission.

Step 4: File Your Forms

File your documents with the District Clerk’s Office where your order is on record.

  • Expect a filing fee (often $50–$75). If you cannot afford it, ask the clerk about the Statement of Inability to Afford Payment of Court Costs from the Texas Judicial Branch.
  • Serve the other parent with the filed petition and hearing notice unless they signed a waiver of service.

Prefer hands-off filing? We can handle preparation, filing, and service for you. Contact our office.

Step 5: Prepare for the Hearing

Bring two copies of all financial documents and any updated evidence of income or expenses. At the hearing, the judge will review your net resources, deductions, and the child’s needs. If you meet the criteria under §156.401, the court will issue a new order reflecting your updated income. Agreed cases can often be finalized in a single session.

Step 6: Implement & Monitor the New Order

After the judge signs, provide a copy of the new order to the Texas Office of the Attorney General (OAG) if they process payments, so wage withholding updates promptly. Track payments and account activity through the OAG portal: Texas Child Support Interactive.
