Understanding child support in Texas is one of the most important steps in your divorce preparation. This guide covers what Texas law requires, what to expect, and how to prepare — in plain language, not legalese.
Section · 01
Texas uses a percentage-of-income model. The non-custodial parent pays a percentage of net resources: 20% for one child, 25% for two, 30% for three, 35% for four, and 40% for five or more children.
Section · 02
Child support calculations include income from all sources: wages, salary, bonuses, commissions, self-employment, rental income, dividends, interest, retirement distributions, and other earnings. Texas calculates from net resources — gross income minus taxes, Social Security, health insurance, and union dues.
Section · 03
Parenting time directly affects child support. When the non-custodial parent has substantial time (more than the standard possession schedule), courts may adjust the support amount downward.
Section · 04
Either parent can request a modification when there's a substantial change in circumstances. Common triggers include job loss, significant income change, change in custody arrangement, or a child's changing needs (medical, educational). Texas allows modification when there's a material and substantial change, or when it's been 3+ years and the new amount would differ by 20% or $100.
What Makes Texas Different
Texas uses one of the simplest child support formulas in the country: a flat percentage of net resources (20% for 1 child, 25% for 2, etc.). This makes Texas child support more predictable than income-shares states.
FAQ

Yes, when there's a substantial change in circumstances — job loss, significant income change, or change in custody. Texas also allows modification if 3+ years have passed and the amount would change by at least 20% or $100.
Generally until the child turns 18 (or 19 if still in high school). Texas support continues until 18 or high school graduation, whichever is later. Support for children with disabilities may continue indefinitely.
Texas has enforcement mechanisms including wage garnishment, tax refund interception, driver's license suspension, passport denial, and contempt of court proceedings. Contact the Texas Attorney General's Child Support Division.
