Child Support in Texas: How It’s Calculated for Corpus Christi Families

Child support questions come up in nearly every family law case involving children, whether it’s part of a divorce, a custody arrangement between parents who were never married, or a modification years after the original order. Texas uses a guideline formula that’s more structured than people often expect, but the formula also depends heavily on how “income” is defined — and that’s where most disputes actually happen.

The Guideline Percentages: Starting Point for Every Calculation

Texas Family Code § 154.125 establishes guideline percentages applied to the paying parent’s net monthly resources: generally 20% for one child, 25% for two children, 30% for three children, 35% for four children, and 40% for five or more children, with a slight reduction in the percentage for each additional child if the paying parent also has children from another relationship. These percentages are the starting point that Texas courts are directed to apply, and in the majority of cases, the guideline amount is what ends up in the final order.

What Counts as “Net Resources”

This is where the calculation gets more involved than most people expect, and it’s frequently the source of disagreement between parents. Texas Family Code § 154.062 defines “net resources” broadly — it includes wage and salary income, overtime pay, commissions, bonuses, tips, and self-employment income, as well as other sources like rental income, retirement and pension income, and certain government benefits.

From that gross figure, specific deductions are subtracted to arrive at “net resources”: Social Security taxes, federal income tax based on the tax rate for a single person claiming one exemption (regardless of the paying parent’s actual filing status or number of dependents), union dues if applicable, and the cost of health insurance or cash medical support for the child. The result of this calculation — not the parent’s gross pay, and not their take-home pay after their actual personal deductions — is what the guideline percentage is applied to.

The Net Resources Cap and What Happens Above It

Texas Family Code § 154.125 includes a cap on the net resources amount to which the guideline percentages apply. This cap is periodically adjusted by the Office of the Attorney General based on changes in the Consumer Price Index, so the specific dollar figure changes over time — it’s worth confirming the current cap amount, since it’s adjusted on a recurring statutory schedule rather than remaining fixed.

For a paying parent whose net resources exceed the cap, the guideline percentage applies only up to the capped amount as a baseline. Family Code § 154.126 allows a court to order additional amounts above the guideline calculation based on the proven needs of the child — but this requires evidence of what those additional needs actually are, rather than simply applying the percentage to the parent’s full income. This distinction matters significantly for higher-income families, where the difference between “guideline support on the capped amount” and “support based on the child’s actual proven needs” can be substantial.

Health Insurance and Medical Support

Texas Family Code § 154.182 requires courts to address medical support for the child as part of a support order — generally requiring one parent to maintain health insurance coverage for the child, with the cost factored into the net resources calculation as described above. Dental support is addressed similarly. These obligations are separate line items from the basic guideline support amount, and a complete child support order addresses both.

When Courts Deviate From the Guidelines

While the guideline percentages are the default, Texas Family Code § 154.123 lists factors a court can consider in deciding whether to apply the guidelines or deviate from them, including the age and needs of the child, the ability of the parents to contribute, any special or extraordinary educational, health care, or other expenses, travel costs associated with a possession schedule, and the financial resources available to support the child from other sources. A deviation isn’t automatic just because one of these factors exists — it requires the court to find that applying the guidelines would be unjust or inappropriate under the specific circumstances.

Child Support for Military and Self-Employed Parents

For families connected to NAS Corpus Christi, it’s worth noting — as discussed in our post on military divorce — that Basic Allowance for Housing and Basic Allowance for Subsistence are generally included as part of a service member’s net resources for child support purposes, even though these allowances aren’t taxed the same way as base pay. For self-employed parents, “net resources” under § 154.062 is based on actual income from the business, not simply the lowest figure reported for tax purposes — and self-employment income is frequently a point of dispute precisely because business expenses, owner draws, and reported income don’t always provide a clear picture of what’s actually available.

Modifying an Existing Child Support Order

Child support orders aren’t permanent and unchangeable. Texas Family Code § 156.401 allows a court to modify a support order if there’s been a material and substantial change in circumstances since the order was entered, or — as an alternative standard — if it’s been at least three years since the order was rendered or last modified and the monthly amount under the current guidelines would differ from the existing order by either 20% or $100, whichever is less. This second standard provides a path to modification based purely on the passage of time and changed guideline calculations, without needing to prove a specific change in circumstances.

Enforcement: What Happens If Support Isn’t Paid

Child support orders are generally enforced through income withholding under Family Code § 158.001, which directs an employer to withhold the support amount directly from a paying parent’s wages. When support isn’t paid and withholding either isn’t in place or isn’t sufficient, enforcement options include contempt proceedings, which can result in jail time for willful non-payment, along with other remedies like license suspension and intercepting tax refunds. The Office of the Attorney General’s Child Support Division also plays a significant role in enforcement for many cases, operating alongside — and sometimes in addition to — enforcement through the family court itself.
