Yes, you can still owe child support with 50/50 custody in Texas. Equal possession time changes how the number is calculated, but it does not eliminate the obligation. When one parent earns more than the other, a Texas court will usually order the higher earner to pay the difference between what each parent would owe under the state’s guideline percentages. If both parents earn the same, the calculation can come out to zero.
Why Equal Time Doesn’t End the Obligation
Texas treats financial support as the child’s right, not something one parent collects from the other. Both parents owe a legal duty to support their child financially, and equal parenting time only satisfies the time-and-care side of that duty. The money side still has to be addressed separately.1State of Texas. Texas Family Code FAM 154.001 – Support of Child
The practical reason is standard of living. If one parent earns substantially more, the child would otherwise experience two very different households depending on which house they woke up in that morning. A support order closes that gap. Under Section 154.001, the court may order either or both parents to pay, and in equal-custody cases the deciding factor is almost always the income difference between the two homes.
How the Offset Calculation Works
Texas has no formula for 50/50 arrangements written into the Family Code. The statutory guidelines were built for a traditional setup with one primary custodian and one paying parent. When parents share time equally, courts typically use what practitioners call the offset method. It has become standard practice even though it is not codified.
The offset works in three steps. The court calculates what each parent would owe the other under the guideline percentages, as if each were the paying parent. It subtracts the smaller figure from the larger. The parent with the bigger hypothetical obligation pays the difference.
A concrete example makes this easier to follow. Say Parent A has $8,000 in monthly net resources and Parent B has $4,000. The guideline percentage for one child is 20%, so 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. If both parents earned exactly the same, the offset would produce a $0 order.
The Guideline Percentages and the Income Cap
The percentage of net resources applied depends on how many children need support. Texas Family Code Section 154.125 sets the standard guidelines:
- 1 child: 20% of net resources
- 2 children: 25% of net resources
- 3 children: 30% of net resources
- 4 children: 35% of net resources
- 5 children: 40% of net resources
- 6 or more: no less than the amount for five children
Parents earning less than $1,000 per month in net resources fall under a reduced schedule, with each tier five percentage points lower. For one child, that drops the rate to 15%.2State of Texas. Texas Family Code 154.125 – Application of Guidelines to Net Resources
These percentages only apply up to a statutory cap on net resources. The cap is adjusted every six years based on changes in the Consumer Price Index, with the current figure published in the Texas Register by the Office of the Attorney General. As of the most recent adjustment, it sits at $11,700 per month. Income above the cap is excluded from the guideline calculation. A court can order additional support above that line if the child’s proven needs justify it, but the parent asking for more must show evidence of those needs.
What Counts as Net Resources
Net resources is a defined term, and it captures more than a paycheck. The calculation 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 after operating expenses and mortgage payments; Social Security (excluding SSI), VA disability benefits (excluding non-service-connected pensions), unemployment, and workers’ compensation; and severance pay, trust income, annuities, gifts, prizes, and spousal maintenance or alimony received.
The deductions subtracted to reach the net figure are Social Security taxes, federal income tax, union dues, and the cost of court-ordered health or dental insurance for the child. If a parent does not pay Social Security taxes, mandatory retirement plan contributions are also deducted.3State of Texas. Texas Family Code FAM 154.062 – Net Resources
One detail catches people off guard. The federal tax deduction is calculated using a fixed formula regardless of how the parent actually files: single filer, one exemption, standard deduction. A parent who files jointly or claims multiple dependents still has their net resources calculated that way.
Adjustments That Matter in 50/50 Cases
The guideline percentages are presumptive. Courts start there but can adjust up or down based on the family’s circumstances. Section 154.123 of the Family Code lists seventeen factors a judge can weigh when strict application would be unfair, and several of them matter a great deal when time is split evenly.
The amount of time each parent has with the child is an explicit factor. In a 50/50 arrangement, this cuts in favor of a downward adjustment because the paying parent is already covering many of the child’s daily costs directly during their possession time. Judges have wide discretion, and some will reduce the offset amount to account for that overlap in spending.4State of Texas. Texas Family Code FAM 154.123 – Additional Factors for Court to Consider
Other factors that frequently come up: childcare costs each parent pays to maintain employment, extraordinary medical or educational expenses, travel costs to exercise the possession schedule, existing obligations to support other children, and non-cash benefits like employer-provided housing or a company car. A parent paying private school tuition or covering significant out-of-pocket medical costs for the child may see those expenses reflected in the final order.
Medical and Dental Support
Separate from the cash payment, Texas courts are required to order medical and dental support. One parent typically has to maintain health and dental insurance coverage, and both parents share responsibility for uninsured medical costs.3State of Texas. Texas Family Code FAM 154.062 – Net Resources
The cost of providing that insurance matters for the calculation. If one parent carries the child on an employer-sponsored plan, the monthly premium is deducted from that parent’s gross resources before the guideline percentage is applied. When the same plan covers other children too, the court divides the total premium by the number of children on the plan to get the per-child cost. That deduction can meaningfully lower the paying parent’s net resources, and with them the offset amount.
Agreeing on a Different Amount
Parents are free to negotiate their own child support arrangement rather than relying on the court to run the guidelines. Texas Family Code Section 154.124 encourages this, allowing written agreements that depart from the standard percentages. Parents can agree to more, less, or $0.
The catch is enforceability. An agreement between parents has no legal force until a judge signs off on it. The court must find that the terms serve the child’s best interest before entering the agreement as an order. If the judge concludes it falls short, the court can send the parents back to revise it or calculate support under the standard guidelines and order that amount instead.5State of Texas. Texas Family Code 154.124 – Agreement Concerning Support
Once a judge approves the agreement and enters it as a court order, the terms are enforceable through all the same remedies as any other support order. The agreement is enforceable as a court order, though, not as a contract, which means it can be modified later under the same standards that apply to any support order.
Changing the Order Later
Either parent can ask the court to modify an existing support order. Under Texas Family Code Section 156.401, a judge can modify the order if the requesting parent shows a material and substantial change in circumstances since the order was last set. Common qualifying changes include a significant increase or decrease in either parent’s income, a job loss, a change in the custody arrangement, increased medical or educational expenses for the child, or the birth of additional children.
Texas also provides an automatic path. If at least three years have passed since the order was last set or modified, and the current guideline amount differs from the existing order by either 20% or $100 per month, that difference alone qualifies as grounds to modify. The three-year rule exists because income and circumstances naturally shift over time.
One point trips people up. The existing order stays in effect until the court signs a new one. A parent cannot reduce or stop payments based on changed circumstances alone. Filing the modification petition is the first step, and the original amount keeps running until a judge says otherwise.
