Yes, you can still be ordered to pay child support with 50/50 custody in Texas. Equal parenting time changes the math, not the obligation. Under Texas Family Code Section 154.001, a court may order either or both parents to pay support, and in shared-custody cases the amount almost always comes down to the difference between what each parent earns.1State of Texas. Texas Family Code FAM 154.001 – Support of Child
Why Equal Time Doesn’t Cancel the Obligation
Texas treats child support as the child’s right, not a transfer one parent collects from the other. Both parents owe a legal duty to support the child financially. Splitting time evenly satisfies the care side of that duty. It doesn’t address the money side.
The concern courts focus on is the standard of living the child experiences in each home. When one parent earns significantly more, the child’s day-to-day life would look very different depending on which house they woke up in. A support order narrows that gap. If both parents earn about the same, the order often comes out to $0. If one earns much more, a payment usually still flows.
How Texas Courts Calculate Support in 50/50 Cases
The Texas Family Code doesn’t contain a formula written specifically for equal custody. The statutory guidelines assume a traditional arrangement with one primary custodian and one paying parent. To handle 50/50 cases, Texas judges and family lawyers use what’s known as the offset method. It isn’t in the statute, but it has become standard practice.
Here’s how the offset works. The court calculates what each parent would owe the other under the standard guideline percentages, treating each as if they were the paying parent. It then subtracts the smaller figure from the larger. The parent with the higher hypothetical obligation pays the difference.
A worked example. Parent A has $8,000 in monthly net resources. Parent B has $4,000. The guideline percentage for one child is 20%. Parent A’s hypothetical obligation is $1,600, and Parent B’s is $800. Subtract $800 from $1,600, and Parent A pays Parent B $800 per month. Same income on both sides would produce a $0 order.
Guideline Percentages and the Income Cap
The percentage applied to each parent’s net resources depends on how many children need support. Texas Family Code Section 154.125 sets these rates:
- 1 child: 20%
- 2 children: 25%
- 3 children: 30%
- 4 children: 35%
- 5 children: 40%
- 6 or more: no less than the amount for five children
The percentages only apply to net resources up to a statutory cap, which the Office of the Attorney General adjusts every six years based on the Consumer Price Index. The current cap is $11,700 per month.2State of Texas. Texas Family Code 154.125 – Application of Guidelines to Net Resources If a parent earns above that, the guideline math stops at the cap. A court can order more if the requesting parent proves the child needs it, but the burden is on that parent to show the need.
What Counts as Net Resources
Net resources is defined by statute and pulls in more than a paycheck. The court starts with all income actually being received, then subtracts specific deductions.
Income that counts includes wages, salary, commissions, overtime, tips, and bonuses; interest, dividends, royalties, and capital gains; self-employment income; rental income net of operating expenses and mortgage payments; Social Security (excluding SSI), VA disability (excluding non-service-connected pensions), unemployment, and workers’ compensation; and severance, trust income, annuities, gifts, prizes, and spousal maintenance received.
From that total, the court subtracts Social Security taxes, federal income tax calculated as a single filer with one exemption and the standard deduction, union dues, and the cost of court-ordered health or dental insurance for the child. Parents who don’t pay Social Security taxes get a deduction for mandatory retirement contributions instead.3State of Texas. Texas Family Code FAM 154.062 – Net Resources
One quirk catches people off guard. The federal tax deduction always uses the single-filer, one-exemption formula, regardless of how you actually file. Married filing jointly with three dependents on your real return doesn’t change the net resources calculation.
Adjustments a Judge Can Make
The guideline percentages are presumptive. Courts start there, but Section 154.123 lets a judge move up or down if strict application would be unfair. Several factors matter especially in 50/50 cases.
The amount of time each parent spends with the child is on the list, and in an equal-custody arrangement it typically supports a downward adjustment. The paying parent is already covering food, utilities, transportation, and other daily costs during their possession time. Some judges reduce the offset amount to reflect that overlap in spending.4State of Texas. Texas Family Code FAM 154.123 – Additional Factors for Court to Consider
Other factors that come up: work-related childcare each parent pays; extraordinary medical or educational costs; travel expenses tied to the possession schedule; existing support obligations for other children; and non-cash benefits like employer-provided housing or a company car. A parent covering private school tuition or significant out-of-pocket medical expenses for the child can point to those costs when arguing for an adjustment.
Medical and Dental Support
Separate from the cash payment, Texas courts must order medical and dental support. Usually one parent maintains health and dental insurance, and both parents share responsibility for uninsured costs.3State of Texas. Texas Family Code FAM 154.062 – Net Resources
The premium the covering parent pays is deducted from their gross resources before the net resources calculation. When the same plan covers other children, the court divides the total premium by the number of children on it to find the per-child cost. That deduction can meaningfully drop the offset in a 50/50 case.
Can Parents Agree on a Different Amount
Yes, and the code encourages it. Section 154.124 lets parents put a written agreement in place that varies from the standard percentages. You can agree to more, less, or nothing.
An agreement has no legal effect until a judge signs off. The court must find that the terms serve the child’s best interest before entering the agreement as an order. If the judge doesn’t agree, the parents can revise the deal or the court will apply the guidelines and order that amount.5State of Texas. Texas Family Code 154.124 – Agreement Concerning Support
Once approved, the agreement is enforceable as a court order rather than as a contract. That matters later: it can be modified under the same rules that apply to any other support order.
When the Obligation Ends
A Texas child support obligation runs until the earliest of:
- The child turns 18 or graduates high school, whichever is later. A child who turns 18 in January but graduates in May is still owed support through graduation.
- Emancipation by marriage, court order removing the disabilities of minority, or other operation of law.
- Death of the child.
The big exception is a child with a physical or mental disability that existed or was known before age 18. In those cases, a court can order support to continue indefinitely.1State of Texas. Texas Family Code FAM 154.001 – Support of Child
Payments don’t stop automatically. The paying parent generally needs to file a motion to terminate and get an updated order. Continuing to pay while the paperwork moves is safer than stopping on your own and risking an arrears balance.
Modifying the Order Later
Either parent can ask for a modification. Under Section 156.401, a court can change the order when there’s been a material and substantial change in circumstances since the order was last set. Common triggers: a significant income change either direction, job loss, a shift in the custody arrangement, new medical or educational costs, or the birth of additional children.
Texas also allows modification on a time-based track. If at least three years have passed since the order was set or last modified, and the current guideline amount differs from the existing order by 20% or $100 per month, that alone is grounds to modify.
The existing order stays in effect until a judge signs a new one. You can’t reduce or stop payments on your own based on a change in circumstances. File the petition, keep paying the current amount, and wait for the new order.
