Understanding Texas Child Support Guidelines
Texas uses established legal guidelines to outline how child support is calculated. The state relies on a percentage-of-income model. The system takes into account the financial circumstances of both parents. Still, the main emphasis is placed on the possessory conservator (non-custodial) parent’s net monthly income.
Either parent may apply for child support, regardless of whether they were ever married to the other parent, as long as they are the primary conservator of the child.
Income Calculation Methods


The calculation process involves several deductions from gross income to arrive at net monthly resources. Allowable deductions typically include:
- Federal income taxes based on a single person claiming one exemption
- State income taxes, where applicable
- Social Security and Medicare taxes (FICA)
- Union dues and professional licensing fees
After establishing net monthly resources, courts apply statutory percentages based on the number of children requiring support. These percentages reflect the state’s determination of what portion of income should support children’s needs.
Only the biological or legal parents’ income is considered when calculating child support in Texas. If a parent remarries, their new spouse’s income is not included in the calculation.
Standard Percentage Guidelines
The Texas Family Code establishes clear percentage guidelines that courts apply to net monthly resources. For families with a net monthly income under the annual capped amount, the percentages are straightforward and mandatory unless specific circumstances warrant a deviation:
- One Child: 20% of their net monthly resources in support
- Two Children: See this percentage increase to 25%
- Three Children: Require 30% of net resources
- Four Children: Increase to 35% of their net monthly income
- Five or More Children: Require 40% of net resources
When net monthly resources exceed the annual capped amount, courts have discretion in applying these percentages to the excess amount. Judges may consider the children’s actual needs, the parents’ financial circumstances, and other relevant factors when determining support for higher-income families.
Factors That Influence Calculating Child Support in Texas


Special Circumstances and Modifications
Medical expenses represent one significant factor influencing child support calculations.
Educational considerations also play a role in support determinations. Private school tuition, tutoring costs, special education services, and extracurricular activities may warrant modifications to standard calculations, particularly when these expenses were established during the marriage. The following factors commonly influence support modifications:
- Extraordinary healthcare or dental expenses not covered by insurance
- Child care costs necessary due to the managing conservator’s employment
- Educational expenses, including private school or special needs services
- Travel expenses for extended visitation in long-distance visitation arrangements
Courts evaluate these circumstances on a case-by-case basis. They examine documentation and evidence to determine whether the modifications serve the children’s best interests.
Required Financial Documentation
Texas courts require both parents to provide extensive financial disclosure to ensure accurate support calculations. Income verification through recent pay stubs, tax returns, and employment records forms the foundation of most cases. Self-employed parents face additional documentation requirements. Business tax returns, profit and loss statements, bank records, and accounting reports help courts understand actual income levels. Professional evaluations may be necessary when business income varies significantly or when questions arise about reported earnings.
Parents should prepare the following documentation for support proceedings:
- Two years of complete tax returns, including all schedules and attachments
- Six months of pay stubs or income statements
- Bank statements from all accounts for the previous year
- Documentation of bonuses, commissions, or irregular income
- Records of business expenses for self-employed individuals
- Evidence of other income sources, including investments or rental properties
The documentation process extends beyond income verification to include expenses and financial obligations. Childcare costs, health insurance premiums, and existing support obligations for other children all require proper documentation.
Parents who experience significant income changes, job loss, or other financial hardships must seek court approval for modifications rather than making unilateral changes to payment amounts.
