How the Texas Child Support calculator works

Texas child support uses a percentage-of-net-resources model rather than a pure income-shares formula. The baseline percentages come from Texas Family Code § 154.125 and are applied to the obligo...

Texas child support laws: what you need to know

Texas child support is famously not an “income shares of both parents” model like Florida (Fla. Stat. § 61.30) or Illinois guideline worksheets (750 ILCS 5/505). Texas applies percentage‑of‑obligor net resources under Tex. Fam. Code § 154.125, with guideline percentages that scale by the number of children before the court (1 child: 20%, 2: 25%, 3: 30%, 4: 35%, 5+: 40% of net resources). “Net resources” is a statutory construct: you start from gross income and then deduct taxes and certain enumerated items to reach the net figure the guidelines apply to—so a gross paycheck number is not the end of the analysis. Texas law also recognizes a cap concept tied to net resources (commonly discussed in materials referencing § 154.125(a) and a monthly figure that has been updated over time—verify the current cap year in your hearing packet rather than relying on any static blog number). If you are comparing states, the biggest mistake is treating Texas like California: California’s Fam. Code § 4055 K/HN/TN guideline is driven by both parents’ net disposable incomes and embedded timeshare math, while Texas starts from obligor net resources and then layers custody deviations in a different procedural posture.

Frequently asked questions

Texas applies percentage guidelines to the obligor’s net resources under Texas Family Code § 154.125 and § 154.062. Courts may deviate under Texas Family Code § 154.123 when guideline application would be unjust or inappropriate. The calculator estimates guideline baseline first, then highlights potential deviation contexts. Consulting a licensed attorney in Texas before taking any legal action is strongly advised.

Support generally continues until the child turns 18 or graduates from high school, whichever occurs later, with exceptions for disability. Termination and continuation issues depend on order language and statutory rules in Texas child support law. Arrears remain collectible after current support ends. A licensed Texas attorney can review your specific facts and give guidance tailored to your case.

Yes. Texas courts can evaluate earning potential where evidence shows voluntary underemployment or underreporting. They may rely on work history, qualifications, and available labor-market evidence, especially when resource disclosures are incomplete. Self-employment records are often central to this dispute. Legal outcomes vary by case — speaking with a Texas attorney before filing is the safest next step.

Modification generally proceeds under Texas Family Code § 156.401 when statutory thresholds are met. Enforcement may include withholding, judgments, and other remedies depending on order terms and arrears history. Filing promptly matters because delayed actions can increase financial exposure. Every case has unique facts. An attorney licensed in Texas can evaluate your specific situation.

Courts analyze net resources under Texas Family Code § 154.062 and often review tax returns, bank records, and business statements to determine reliable support income. They may average volatile earnings or structure support to address variable compensation. Unsupported deductions are frequently challenged. This estimate is a planning tool. Verify current Texas law with a licensed attorney.

A parent’s duty to support their child continues despite remarriage or cohabitation. Household changes may affect practical budgets or available coverage, but support remains a child-centered obligation under Texas law. Where finances materially change, modification may still be pursued through statutory procedure. Consulting a licensed attorney in Texas before taking any legal action is strongly advised.

Child support is generally not taxable income to the recipient and not deductible by the payer under current federal treatment. That said, tax planning still matters for withholding, credits, and household cash flow. Parties should confirm assumptions in real filing scenarios. A licensed Texas attorney can review your specific facts and give guidance tailored to your case.

You can file without counsel, but statutory net-resource disputes, deviation arguments, and enforcement issues can be technical. Legal representation helps build admissible records and protect against avoidable calculation errors. This is especially important in self-employment and contested-parenting-time cases. Legal outcomes vary by case — speaking with a Texas attorney before filing is the safest next step.
