Texas uses the Percentage of Income model to calculate child support, which means child support is calculated as a flat percentage of the non-custodial parent's income.
Under the Percentage of Income model, child support is calculated as a percentage of the non-custodial parent's income (gross or net, depending on the state). The custodial parent's income is generally not considered. Typical percentages are around 20% for one child, 25% for two children, 30% for three, and so on. This means every dollar of hidden income directly reduces child support.
The Texas child support guidelines provide specific tables and formulas that courts use to determine the appropriate amount. Judges can deviate from these guidelines in special circumstances, but the calculated amount is the presumptive starting point.

In Texas, income includes wages, tips, bonuses, commissions, self-employment income, interest, dividends, rental income, severance pay, retirement benefits, trust income, annuity payments, and Social Security benefits.
Importantly, courts in Texas can look beyond what appears on a tax return. If a parent is self-employed or owns a business, the court can examine business records, bank statements, and lifestyle evidence to determine true income. Personal expenses paid by a business, unreported cash income, and excessive business deductions can all be added back as income for child support purposes.
