Child Support
Texas Guidelines
Modification
4 min read
Child support isn't just a number — it's an ongoing obligation that can be challenged, adjusted, and enforced. Knowing how it works protects you on both sides of the equation.
Whether you're the parent paying support or the one receiving it, understanding how Texas calculates child support — and under what conditions it can change — is essential to protecting your family's financial stability. The guidelines provide a starting point, but the final order depends on the full picture of your circumstances.
Statutory Guidelines
How Texas Calculates Child Support
Child support in Texas is primarily determined using statutory guidelines based on the paying parent's net monthly income. The percentage applied increases with the number of children:
-
→
1 child — 20% of net monthly income
-
→
2 children — 25% of net monthly income
-
→
3 children — 30% of net monthly income
-
→
4 children — 35% of net monthly income
-
→
5+ children — not less than 40% of net monthly income
⚖
Income Cap
Texas guidelines apply only up to a statutory cap on net monthly income. Income above that threshold is not automatically subject to the percentage formula — though courts can order additional support beyond the cap in appropriate circumstances.
Net Income Defined
What Counts as Income — and What Doesn't
Net income for child support purposes is broader than most people expect. It includes wages, salary, bonuses, commissions, self-employment income, rental income, and most other sources of earnings. From that gross figure, Texas allows specific deductions to arrive at net monthly income:
-
→
Federal and state income taxes (based on the tax rate for a single person)
-
→
Social Security and Medicare (FICA) taxes
-
→
Health insurance premiums paid for the child
-
→
Union dues and other allowable deductions
The goal is to ensure children receive consistent financial support regardless of how the parents structure their living arrangements. Accurately documenting all income sources — and all legitimate deductions — is critical to arriving at a fair number.
Judicial Discretion
When Courts Deviate from the Guidelines
Courts may deviate from standard guidelines when applying them would not serve the best interest of the child. Judges have discretion to tailor orders to the unique needs of the family — and the factors they consider include:
-
→
The child's special needs or extraordinary medical expenses
-
→
Educational costs or extracurricular expenses
-
→
Significantly unequal parenting time between the parties
-
→
Other resources or assets available to either parent for the child's benefit

Know Your Position
If you believe the standard guideline amount is either too high or too low given your family's circumstances, you have the right to present evidence and argue for a deviation. Courts respond to documented facts — not assumptions.
Modification
When and How Child Support Can Be Changed
Child support orders are not permanent. Texas law allows for modification when there has been a material and substantial change in circumstances since the last order was entered. Common qualifying events include:
-
→
Job loss or a significant change in either parent's income
-
→
A change in the child's medical needs, living situation, or primary caregiver
-
→
Three years have passed since the last order and the amount would differ by at least 20% or $100 under current guidelines
-
→
A material change in either parent's health insurance coverage for the child
Modifications require a formal court order — informal agreements between parents are not enforceable and can create legal complications. If your circumstances have changed, acting through proper legal channels protects both you and your child.
