How Child Support Is Calculated in Texas

When parents separate or divorce, one of the most common questions is how child support is determined. In Texas, child support is based on statutory guidelines designed to provide consistency while still allowing for adjustments when needed.

Understanding how these calculations work—and what factors may affect them—can help parents set realistic expectations and plan ahead.

What Income Is Used to Calculate Child Support?

Texas child support is typically based on the paying parent’s net monthly resources. This includes:

• Wages and salary 

• Commissions, bonuses, and overtime 

• Self-employment income 

• Rental income and certain benefits 

After calculating total income, certain deductions are applied, such as:

• Social Security taxes 

• Federal income tax (based on guidelines) 

• Health insurance premiums for the child 

The result is the net resources used for child support calculations.

Texas Child Support Guidelines

Texas applies a percentage-based system depending on the number of children before the court:

• 1 child: 20% of net resources 

• 2 children: 25% 

• 3 children: 30% 

• 4 children: 35% 

• 5 children: 40% 

• 6 or more children: Not less than 40% 

These percentages apply up to a certain income cap, which is periodically adjusted under Texas law.

Real-World Examples

Example 1: One Child

A parent earns $5,000 in net monthly resources.

• 20% of $5,000 = $1,000 per month in child support 

Example 2: Two Children

A parent has $6,000 in net monthly resources.

• 25% of $6,000 = $1,500 per month 

Example 3: Income Above the Cap

If a parent earns more than the guideline cap, the percentage is typically applied to the capped amount. However, courts may consider additional support depending on the child’s proven needs.

Additional Factors That May Affect Child Support

While guideline calculations are the starting point, courts may adjust child support based on factors such as:

• The child’s specific needs 

• Medical or educational expenses 

• The amount of time each parent spends with the child 

• Whether a parent has other children to support 

• Agreements reached between the parties 

These factors may result in deviations from standard guideline amounts.

Medical and Dental Support

In addition to monthly child support, Texas courts require that medical and dental support be addressed. This often includes:

• Providing health insurance coverage 

• Sharing out-of-pocket medical expenses 

These obligations are typically outlined separately in the court order.

What If Income Changes?

Child support is not automatically adjusted when circumstances change. If a parent experiences a significant change in income or financial circumstances, a modification may be necessary.

To request a change, a parent must generally show a material and substantial change in circumstances or meet statutory thresholds for review.

The Importance of Accurate Calculations

Accurate income reporting and proper application of guidelines are essential. Miscalculations or incomplete information can lead to disputes or enforcement issues later.

Taking the time to understand how support is calculated can help both parents avoid confusion and plan more effectively.
