If you are staring at a Texas Attorney General worksheet—or a court order that suddenly feels “too high” or “too low”—you are not imagining the math. Texas is the second-most populous state in the country, and it uses one of the cleanest child support models in the United States: a percentage of the obligor’s net monthly resources, not a California-style algebraic monster with twelve moving parts. That simplicity is a blessing when you need a ballpark fast. It is also a trap when people confuse gross pay on a pay stub with net resources under Tex. Fam. Code § 154.062, or when they forget the $11,700 monthly cap on net resources (updated September 2025) that stops guideline percentages from running forever up the income ladder.
This article is written for parents who want straight answers: how Texas calculates child support in 2026, what actually counts as net resources, what the 20% / 25% / 30% / 35% / 40% ladder means in real dollars, how the cap bites high earners, how custody time can still matter even though Texas is not an “income shares” state like Florida or New York, and how modification works when life changes. At the end, you can jump into TheLegalCalc’s Texas child support calculator to stress-test your own numbers before you pay a retainer or walk into mediation unprepared.
One tone note up front: Texas law loves labels like obligor, obligee, and SPO (Standard Possession Order). You do not need to sound like a paralegal at dinner—but you do need to know which parent is the paying parent under the guideline, because Texas starts from that parent’s net, not both parents’ combined gross the way Florida does.
How Texas Calculates Child Support
The statutory backbone. Texas guideline child support is anchored in Tex. Fam. Code § 154.125, which applies fixed percentages to the obligor’s net monthly resources for children covered by the order. The percentages are not a secret handshake: 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more—with statutory adjustments when the obligor has other children outside the case. Courts presume the guideline is just and appropriate unless a party proves otherwise under the deviation framework in § 154.123.
Why “net resources” matters more than your W-2. Texas does not slap the percentage on your gross paycheck. The statute walks through what counts as income and what you subtract to reach net monthly resources under § 154.062. Think of it as: start from money that actually shows up in the real world, then subtract the boring stuff you cannot spend twice—federal income tax withholding, Social Security (6.2%), Medicare (1.45%), state income tax (Texas: zero), health insurance premiums for the children in the order, and reasonable child-care costs necessary for a parent to work. If you skip those subtractions, you will overstate support and panic for no reason.
Example 1 — one child, $6,000 gross (illustrative “real life” walkthrough). Imagine a paying father with $6,000 monthly gross wages, typical withholding, one child on his insurance, and no wild bonus structure. A planning-style breakdown might look like: federal income tax roughly $720, FICA roughly $459, children’s health insurance roughly $200, leaving net resources around $4,621. Guideline support is 20% × $4,621 ≈ $924/month before the court adds medical support orders, cash medical support, or other adjustments. Your numbers will wiggle with W-4 elections and pre-tax deductions, which is why you should treat this as a conversation starter, not a filed order.
Example 2 — two children, $3,000 gross. A tighter income picture might net out near $2,550 after taxes and FICA (illustrative). Two kids means 25%, so 25% × $2,550 ≈ $637/month guideline. That is the same statute, different bracket—this is why Texas feels “predictable” compared with states where the worksheet hides the policy choices inside a table.
Example 3 — when the cap saves the day. Texas law caps the portion of net resources subject to the guideline percentages at $11,700 per month (effective September 2025). Suppose a high earner’s net after taxes still lands around $15,000—above the cap. You do not multiply 20% × $15,000. You multiply 20% × $11,700 = $2,340/month for one child at the guideline’s resource ceiling, and then courts may address amounts above the cap using different legal tools depending on the facts and pleadings. If you assumed 20% × $15,000 = $3,000, you just invented a payment Texas law does not require at the guideline step.
Custody is not “ignored”—it is just not the headline. Texas is famous for obligor-percentage math, but parenting time still shows up in real cases through possession orders, expanded schedules, and deviation arguments when guideline application would be unjust or inappropriate. More on that in the custody section—because the internet oversimplifies Texas into “time does not matter,” and that is not how courtrooms behave when possession is truly equal or when expenses are wildly asymmetric.
The $11,700 Cap — What It Means for High Earners
The $11,700 figure is the kind of rule that sounds small on paper and feels enormous at the kitchen table. It is not a “maximum child support in Texas forever” label; it is a cap on net monthly resources used in the guideline percentage step under § 154.125. Practically, it means high earners hit a ceiling where the guideline math stops scaling up—even if their lifestyle still looks expensive.
Why legislatures cap. Guideline systems try to balance predictability (parents can plan) with fairness (children should share in economic upside). Without a cap, percentage models can produce eye-popping transfers that become politically and practically difficult for courts to administer as “presumptively correct” in every case. Texas responds by letting the guideline run on capped resources, then allowing arguments about additional needs and deviations where facts justify more than the baseline structure.
How to talk about it without sounding greedy. If you are the recipient, the cap is not a personal insult—it is a statutory design choice you can still address through medical support, cash medical, uninsured expenses, and sometimes above-guideline arguments tied to proven needs and the child’s best interest. If you are the payor, the cap is not a “get out of parenting free” card either—courts can still allocate health insurance, dental, and daycare with teeth, and enforcement tools for nonpayment are brutal when arrears stack.
A simple mental model. Step one: compute net resources honestly. Step two: if net is above $11,700, pretend it is $11,700 for the percentage math. Step three: apply the correct percentage for the number of children. Step four: add court-ordered medical and child-care components as separate lines so you do not double-count or forget them.
Where people fight anyway. High earners fight about bonus income, RSUs, owner draws, and business expenses that may or may not reduce true cash available for support. Texas courts can examine whether deductions are legitimate or whether income is intentionally suppressed. If your financial life is not “W-2 simple,” budget for real discovery—bank statements, corporate returns, and payroll detail—not a three-minute web estimate.
How to Calculate Net Resources in Texas
If you only remember one sentence from this article, remember this: Texas guideline support is a percentage of net resources, not a percentage of “what I feel like I have left.” The statute defines net resources broadly to include wages, self-employment income, interest, dividends, rental income, and other categories, then subtracts specific items like federal taxes, Social Security, Medicare, the child’s health insurance premium, and work-related child care—see Tex. Fam. Code § 154.062 for the full list your lawyer will use line-by-line.
Federal income tax withholding. Use realistic withholding, not fantasy. If you are intentionally under-withholding to inflate “net,” a court can normalize you back to reality. If you are over-withholding to shrink “net,” expect pushback from the other side.
State income tax. Texas does not impose a state income tax on wages the way New York does. That is a real cross-border difference: a Texas pay stub is not trying to hide a giant state-tax hole the way a NYC pay stub might.
FICA: Social Security (6.2%) and Medicare (1.45%). These are the usual payroll taxes people see on pay stubs. Self-employed parents have a different presentation (Schedule SE concepts), but the policy goal is the same: approximate real payroll tax drag.
Health insurance for the child. If you pay the premium that covers the kids in the order, that belongs in the deduction column for net resources purposes—not as a vague “I spend a lot on kids” anecdote.
Child care necessary for employment. Daycare with a real provider contract is the classic example. Courts dislike “babysitter cash” with no receipts. Bring invoices, provider tax IDs, and schedules that match work hours.
A step-by-step you can actually follow at home. (1) Write down gross monthly income from all guideline sources. (2) Subtract taxes and FICA using documented withholding or a defensible estimate. (3) Subtract the children’s health premium attributable to the order. (4) Subtract reasonable work-related child care tied to earning income. (5) Compare the result to the $11,700 cap. (6) Multiply by the correct percentage for the number of children. That is the Texas “spine” of the calculation—then lawyers argue the edges.
Common self-help mistakes. Counting 401(k) as if it disappears from income forever. Mixing in new spouse income (usually not the driver you think). Forgetting that multiple families can change the percentage structure when the obligor has other children. Using last year’s tax refund as “income” without understanding whether it is recurring. If you are doing this alone, at least do it twice: once optimistic, once conservative, and see how wide the band is—wide bands mean “hire counsel.”
Does Custody Time Affect Child Support in Texas?
Texas is not Florida: you will not see a neat “20% overnight threshold” baked into the same place in the statute. But custody still matters because kids cost money in two houses, and because Texas law allows courts to deviate from the guideline when application would be unjust or inappropriate under Tex. Fam. Code § 154.123.
Standard Possession Order (SPO). Many families operate under an SPO-style pattern where the noncustodial parent has possession on first, third, and fifth weekends, Thursday evenings during the school year, extended summer time, and a holiday rotation. A rough shorthand people use in planning conversations is that the noncustodial parent might land around about 42% of the time under a classic SPO—not legal advice, just why you keep hearing “42%” in Texas parenting Facebook groups. The actual percentage depends on your order language, holidays, and reality on the ground.
Expanded SPO. When parents agree (or a court orders) an expanded schedule under Tex. Fam. Code § 153.317, the noncustodial parent can pick up additional weekday overnights around the standard weekend pattern. That can change expenses and sometimes becomes part of the factual story for deviation arguments—especially when possession approaches equal and each household is truly carrying half the week-in, week-out costs.
Deviations are possible—not automatic. Texas courts can consider factors like the child’s age, extraordinary educational or health needs, travel costs, and possession arrangements. The key is evidence: calendars, school records, receipts, and credible testimony. “I feel it is unfair” is not a statute; § 154.123 factors are.
Practical negotiation tip. If you are near equal possession and both parents earn real incomes, do not assume the guideline percentage is the last word on what fair looks like in mediation. You might still start from guideline as the anchor—Texas culture often does—but your final deal might include adjustments to healthcare splits, private school, or activities that matter more than fighting the percentage by a point.
If you are enforcing an old order. Possession and support are legally separate problems, but parents experience them as one fight. If possession changed years ago but the order never updated, do not be shocked if the Attorney General’s accounting still follows the old paperwork until someone files to modify.
How to Modify Child Support in Texas
Child support orders are not tattoos. When income, custody, or a child’s needs change in a material way, Texas law provides a modification pathway—but you should expect procedure, not magic.
Chapter 156 framework. Texas modifications generally live in Fam. Code Chapter 156. A common shorthand lawyers use is that modification may be available when there has been a material and substantial change in circumstances, sometimes paired with timing rules like three years since the last order or a change large enough to move the monthly amount by 20% or $100 (these are the kinds of thresholds people discuss in consults—bring your actual order and your attorney will translate it into the correct legal test for your case).
What counts as “material.” Involuntary job loss with real documentation is the classic example. A big promotion is another. A new baby in another household can change percentage structures. A medical crisis can change needs. What usually fails is “my ex makes me mad” without a financial or child-centered change tied to admissible facts.
Retroactivity reality. People want modifications to start the day their life changed. Courts often work from filing dates and procedural rules that mean delays cost money. If you wait a year to file after a layoff, do not be surprised if you still owe the prior amount for months you thought were “obvious.”
Where to file and who is involved. Some cases involve the Office of the Attorney General when public assistance or enforcement services are part of the picture. Private divorce decrees may be modified in district court. Procedures differ; mistakes here waste months.
Evidence checklist. Updated pay stubs, termination letters, unemployment filings, new lease costs (where relevant), daycare invoices, insurance premium statements, and a clear proposed order. If you are self-employed, bring profit-and-loss statements that tie to bank deposits—not a napkin margin guess.
Mediation vs hearing. Many counties push mediation hard. That is not a punishment; it is where a lot of Texas families land on a workable number without paying for a full trial record.
Run the Numbers on the Texas Child Support Calculator
When you are done reading statutes on your phone at 1 a.m., the useful next step is to model your situation with clean inputs. TheLegalCalc’s Texas child support calculator is built to help you translate gross → net resources → percentage → monthly guideline in a way you can print and take to a consult.
Use it like this: enter a realistic gross, back out taxes and FICA the way your pay stub actually behaves, include the kids’ insurance premium if you pay it, include daycare if it is truly work-related, and then look at how the cap changes the story for high earners. Then change one variable at a time: add a second child, remove daycare, adjust income—watch how fast the number moves.
What the calculator will not do. It will not file your motion, serve the other parent, negotiate holiday possession, or predict a judge’s deviation. It will help you avoid the two classic Texas errors: gross vs net confusion and cap blindness.
Next step: open /child-support-calculator/texas and run a conservative and an aggressive scenario. If the spread between them is huge, that is your signal to stop DIY-ing and hire a Texas family lawyer for a paid strategy session.

Frequently asked questions
Texas guideline child support starts with the **obligor’s net monthly resources** under **Tex. Fam. Code § 154.062**, not the obligor’s gross paycheck headline. Once net resources are calculated—and compared to the **$11,700** monthly cap on resources used in the guideline percentage step under **§ 154.125**—the court applies the statutory percentage for the number of children in the case: **20%** for one child, **25%** for two, **30%** for three, **35%** for four, and **40%** for five or more, subject to adjustments when the obligor has other children to support. After that baseline, orders commonly add separate components for **medical support** and **cash medical support**, and may allocate **child care** costs tied to employment. Courts presume the guideline amount is just and appropriate unless a party proves a deviation is warranted under **§ 154.123** with evidence about the child’s needs, possession, travel costs, and other statutory factors. Because Texas is a “percentage of obligor net” state, the custodial parent’s income is not blended into the same starting point the way it is in **income shares** states like Florida—though the custodial parent’s situation can still matter for deviations and for expense allocations.
People mean different things when they say “maximum.” If you mean the **guideline percentage cap on net resources**, Texas law caps the **net monthly resources** subject to the guideline percentages at **$11,700** (updated **September 2025**). For a one-child case, that means the guideline percentage step applies to **$11,700** of net resources even if the obligor’s true net is higher—so **20% × $11,700 = $2,340/month** at the guideline percentage stage before medical and child-care additions. If you mean “the most a parent can ever be ordered to pay,” the answer is messier: courts can still order **medical support**, allocate uninsured expenses, and address above-cap realities through statutory mechanisms and findings when justified by evidence and the child’s best interest. If you mean “maximum enforcement pressure,” that is a different conversation: arrears can draw **wage withholding**, **license** issues, and **contempt** risk depending on procedural posture. For planning purposes, start with the **$11,700** guideline cap so you do not multiply percentages against fantasy income.
**Net resources** is a defined term, not a vibe. Under **Tex. Fam. Code § 154.062**, courts start from income and resources that count under the statute—wages, self-employment earnings, certain benefits and investment income depending on the facts—and then subtract permitted items like **federal income tax**, **Social Security taxes**, **Medicare taxes**, **state income taxes** (Texas has none on wages like many states), **union dues** if actually withheld, **health insurance premiums for the children**, and **reasonable and necessary** child-care costs for the obligor to keep earning income. The point is to approximate **actual spending power** available for child support, not to reward clever accounting. Common disputes include whether bonuses are recurring, whether self-employment expenses are legitimate, whether a new spouse’s income is relevant (often misunderstood), and whether a parent is voluntarily underemployed. If your “net” number differs wildly from your pay stub reality, expect the other side to ask for bank statements and tax returns until the story reconciles.
Sometimes yes—**but not because you want it**, and not because your ex remarried. Texas modifications generally require a **material and substantial change** in circumstances under the modification rules in **Fam. Code Chapter 156**, and timing thresholds sometimes matter (many people discuss a **three-year** rule or a **20% / $100** change test—your lawyer will apply the correct test to your order). Examples that frequently support a downward adjustment include **involuntary job loss** with documentation, a **disability** that reduces earning capacity, a **material change in custody** that changes the expense reality, or a change in the number of children the law requires you to support. What usually fails is “I have new bills” without a legally recognized change, or voluntary career choices that look like intentional underemployment. Procedure matters: until a court signs a new order, the old order typically remains enforceable, so delaying a filing can be expensive. If you are the recipient and you think the other parent is manipulating income, your response is also evidence-driven: discovery, subpoenas, and sometimes imputation arguments.
Nonpayment is not a budgeting disagreement—it is a legal problem that can escalate quickly. Texas enforcement tools can include **wage withholding**, **license suspension** issues in administrative processes, **liens**, **contempt** proceedings in court, and **interest** on arrears depending on the order and context. Federal criminal nonpayment statutes exist in extreme cases, but day-to-day life for most families is shaped by state enforcement and private contempt motions, not dramatic TV-law moments. If you truly cannot pay because income collapsed, the responsible move is usually to **seek a modification** with proof rather than silently falling behind—because arrears often do not vanish retroactively. If you are receiving support and the other parent stopped paying, document everything: missed payments, partial payments, and communications. Enforcement strategy depends on whether the case is primarily OAG-driven or private decree-driven, and mistakes there waste months. The boring truth: paying something negotiated temporarily while litigation proceeds is sometimes cheaper than building a giant arrears balance.
