Key takeaways

    • Percentage-based guidelines: Texas typically uses 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more.

    • Based on net resources: Support is calculated on net monthly resources after specific deductions, not gross income.

    • $11,700 monthly cap: Guideline percentages generally apply to the first $11,700 of net monthly resources (effective September 1, 2025).

    • Medical and dental support are part of the order: Child support orders usually address health insurance and the split of uninsured costs.

    • Modifications are possible: You can request a change after a material change in circumstances, or after three years if the guideline amount would differ by 20% or $100.

Texas child support percentage guidelines

Texas guidelines start with a straightforward idea: once the court determines the paying parent’s net monthly resources, it applies a percentage based on the number of children in the case. The standard guideline percentages are: 20% (1 child), 25% (2), 30% (3), 35% (4), 40% (5), and not less than the amount for 5 children (6+).



A quick example: if your net monthly resources are $5,000 and you’re paying support for two children, the guideline amount is typically 25%, or $1,250/month (before considering things like health insurance provisions).



One important detail people miss: Texas guideline support is primarily based on the paying parent’s net resources, not a combined-income model. Judges can deviate, but the guideline number is the usual starting point.

What counts as income for child support?

Texas uses the term “resources,” and it’s broader than just your paycheck. The court looks at income from many sources, then applies only the deductions Texas law allows to reach “net resources.”

Included income

You don’t need to memorize a giant list, but you do want to think beyond base salary. Common sources that may be counted include:

    • Wages/salary (including overtime, commissions, bonuses)

    • Self-employment or business income (after appropriate expenses)

    • Interest/dividends and other investment income

    • Rental income

    • Retirement/pension income

    • Unemployment or disability benefits (in many situations)

Texas law is intentionally broad here, so if income is available to you, assume it may be part of the calculation unless a specific exclusion applies.

Excluded income

Some items generally aren’t included in net resources (for example, certain means-tested public benefits). The exclusions can be specific, so if a big part of your income falls into a gray area, it’s worth getting it reviewed using the statute’s definition rather than guessing.

Net resources calculation

Here’s the piece that catches a lot of people off guard: Texas does not let you subtract whatever bills you have to get to a fair number. The law lists specific deductions, and those deductions are what the court uses to calculate net resources.



Typically, net resources are calculated by taking your gross monthly income and subtracting allowable items such as:

    • Social Security/FICA (or equivalent, depending on how you’re paid)

    • Federal income tax (calculated using the statute’s assumptions)

    • Union dues (if applicable)

    • The cost of the child’s health insurance premium (when applicable)

If you’re self-employed, the process can get more technical because the court may look closely at business income, business expenses, and consistency over time.

Cap on child support calculations

Texas applies the guideline percentages only up to a maximum level of monthly net resources (the cap). As of September 1, 2025, the cap is $11,700 in net monthly resources for guideline calculations.



What does that mean in real terms?

    • If your net monthly resources are $11,700 or more, the guideline amount for one child is typically $2,340/month (20% of $11,700).

    • For two children, it’s typically $2,925/month (25%).

    • For three children, typically $3,510/month (30%), and so on.

Income above the cap doesn’t automatically disappear from the conversation. In higher-income cases, support above the guideline amount can come up when there are proven needs that justify it, but it’s not a percentage of everything you make forever.

Factors that can modify child support amounts

Most cases track the guidelines, but Texas courts can order a different amount if the guideline number would be unjust or inappropriate and the evidence supports a deviation.



A few situations where deviations commonly come up include:

    • You support other children (the multiple family situation)

    • A child has extraordinary medical, psychological, or educational needs

    • Travel or possession schedules create unusually high expenses

    • There are other significant factors affecting what’s fair and appropriate for the child

The key idea is that deviations aren’t automatic. If you want a court to go above or below guidelines, you generally need facts, documentation, and a clear explanation of why the guideline number doesn’t fit the situation.

Medical support and additional expenses

In Texas, child support is often more than a single monthly amount. Orders commonly address medical support (health insurance) and the handling of uninsured expenses.



Texas also defines when insurance is available at a reasonable cost. For medical support, “reasonable cost” is generally tied to 9% of the obligor’s annual resources (and there’s a separate standard for dental).



On top of premiums, many orders specify how to split costs for copays, prescriptions, orthodontics, therapy, and other uninsured expenses. Some families also negotiate or litigate additional categories (such as extracurriculars or certain educational costs), depending on the child’s needs and the parents’ finances.

Modifying child support orders

Child support doesn’t stay locked in place forever. You can ask the court to modify support when:

    • There’s been a material and substantial change in circumstances, or

    • It’s been three years since the last order (or last modification) and the new guideline amount would differ by 20% or $100.

A couple of practical points that matter in real life:

    • A modification usually requires a formal filing and court process; it’s not automatic.

    • If your income changes, it’s usually smarter to address it early rather than letting arrears build up.

Child support arrears and criminal penalties in Texas

Texas takes enforcement seriously. If support isn’t paid, the state can use tools like wage withholding and other enforcement mechanisms through the child support system.



In more serious situations, unpaid support can also become a criminal issue. Under Texas law, criminal nonsupport involves intentionally or knowingly failing to provide support for a child, and it’s classified as a state jail felony (with an affirmative defense if you truly couldn’t provide support).

Getting help with child support

Child support looks simple on paper, but the outcome can change fast when you add real-world details like self-employment income, irregular bonuses, multiple children across households, or disputes about what should (and shouldn’t) count as income.



Marble can help you understand how Texas guidelines apply to your situation, review support calculations for accuracy, and support you through modifications or enforcement steps when circumstances change. And if you’re walking into a negotiation, you’ll usually feel more in control when you understand what the guideline number is likely to be and why.
