If your financial situation has changed and you believe your child support order should be reduced, don’t wait. Acting early can prevent unpaid support from escalating.
Child support helps meet a child’s basic needs, such as food, shelter, clothing, and health care. In Texas, child support is ordered by the court and does not automatically change when life changes. Many parents ask, “Is child support mandatory in Texas?” The answer is yes. Because it is required by law, parents cannot reduce or stop payments on their own. If you want to reduce your child support payments, you must ask the court and meet certain legal requirements.
This article explains child support in simple terms, including how it’s calculated, when it can be reduced, whether it’s optional, and what steps you can take if your situation has changed.
How Child Support is Calculated in Texas
Texas uses statutory guidelines when calculating child support. These guidelines ensure that child support is fair and consistent for each specific case. The court considers the paying parent’s monthly tax and deduction income (net income) and uses a fixed percentage of that income to calculate child support.
In most cases, Texas courts use these percentages:
- One child: 20 percent of net income
- Two children: 25 percent
- Three children: 30 percent
- Four children: 35 percent
- Five or more children: at least 40 percent
Depending on whether the paying parent has more than one child, these percentages may be adjusted. There are many factors the court will take into account when calculating child support, including:
- Wages and salaries
- Overtime, bonuses, and commissions
- Self-employment income
- Unemployment or disability benefits
Don’t try to hide any of your income. This can lead to fines. Some expenses are deducted before child support, such as:
- Federal income tax
- Social Security and Medicare Taxes
- Health insurance costs for the child
After deductions are applied, the court uses the remaining amount to calculate child support.
When a child support order can be legally modified
In Texas, child support orders can only be modified through legal process and must be approved by a judge. Even if both parents agree to modify the terms, the new agreement requires a court order modification to be enforceable. Any private child support agreement—including any support arrangements—without judicial review has no legal authority and cannot be legally enforced unless it is formally filed, reviewed, and signed by a court.
What justifies the modification?
For a modification request to be considered, the change in circumstances must be mandatory, real and ongoing and not temporary or voluntary. Common legitimate reasons include:
- Significant reduction in income due to loss of involuntary employment
- Cut back on work hours not initiated by parents
- Changes in physical custody or parenting time
- New or increased medical, educational, or special needs of the child
A parent requesting a modification must demonstrate that circumstances have materially changed and that the changes affect the financial responsibility specified in the original support order.
When courts generally refuse to amend
Texas courts are unlikely to grant a request to reduce or terminate child support if:
- Parents voluntarily quit their jobs or deliberately reduce their income
- Financial difficulties are short-term or self-inflicted
- Parents try to bypass the legal process by relying on informal agreements or verbal arrangements
Legal enforcement and liability
The obligation to pay child support is a financial obligation imposed by the court, and it remains active until formally modified. Attempting to avoid payments through private contracts or unapproved changes may result in enforcement actions including wage garnishment, fines and legal consequences.
Is child support optional in Texas?
Many people wonder, “Is child support optional in Texas?” No, child support is not optional in Texas. Child support is about the child, not the parent, so parents can’t choose to ignore it. However, parents can request a change. If the judge believes that the change is not in the best interests of the child, it will be denied. Failure to pay your child support can result in severe penalties, including:
- Unpaid balances are accruing with interest
- Wage garnishment
- Suspension of driver’s or professional license
- Court penalties including jail time
Understanding your options moving forward
You can reduce child support in Texas, but only through the court. Child support does not automatically change, even if your income drops. To obtain a reduction, you must demonstrate an actual and ongoing change in circumstances, such as a loss of employment, reduced income, or a change in custody. Child support is not optional, and stopping payments without court approval can lead to serious penalties.

It is possible to reduce child support in Texas, but it requires following a legal process. Courts use set guidelines to calculate support and allow changes only when there is a significant and lasting change in circumstances. Parents cannot privately change or override a child support order, even if both agree. Acting quickly, providing adequate evidence, and understanding how the system works can help protect your finances while providing for your child’s needs.
If your financial situation has changed and you believe your child support order should be reduced, don’t wait. Acting early can prevent unpaid support from escalating. Consider speaking with a Texas family law attorney to understand your options and make sure your application is handled correctly.
