What Is the Minimum Child Support Percentage in the State of Texas for One Child?

Texas guidelines state that a noncustodial parent should pay 20 percent of net income for a single child. This calculation is for parents earning less than $7,500 per month.

This calculation is based on net income, which includes salary, self-employment income, interest, dividends, net rental income and disability income. It does not include welfare payments nor payments from a new spouse. Social Security tax, federal income tax, union dues and health insurance dues are deducted before the calculation of child support. If a court believes the individual is not earning within expectations, the amount is based on the earning potential of the individual rather than the actual amount the individual earns.
