Child Support Laws

What Is Child Support?

Child support is an ongoing payment by a non-custodial parent to assist with the financial support of their children. Child support payments are often determined during the process of dissolution of a marriage through divorce, though the only requirements for requesting child support payments are establishment of paternity and maternity.

Child support is handled on a state level, and Missouri has a set of specific child support guidelines. On this page you can learn about how child support is calculated in Missouri, how custody split and extraordinary costs affect child support payments, and more.




Missouri Child Support Law Summary

Missouri uses the "income share" method for calculating child support payments, which is designed to ensure that both the custodial and non-custodial parents contribute to their child's upkeep.

In the event of parents sharing custody of a child, the Missouri judge who sets child support may deviate from the basic child support formula to account for this. Other special situations accounted for under Missouri's child support law include childcare costs, extraordinary medical costs and college costs. These costs may be additions to the basic Missouri child support order.

What Factors are Considered in Determining Child Support Payments?

The obligation of a parent to make child support payments may be terminated as follows:



  • Given the state case registry or child support order contains the child's date of birth, after the child reaches the age of 21, if the child support order does not specifically require payment of child support beyond age of 21.


  • when the parent receiving child support submits a sworn statement notifying the obligor parent of the child's emancipation


  • when the parent paying child support files a sworn statement or affidavit with the court which entered the order establishing the child support obligation, or the family support division for an order states that the child is emancipated and is not responded to in writing within thirty days of receipt by the child support obligee


  • entered the order establishing the child support obligation, or the family support division for an order entered, when the parent paying child support files a sworn statement with the court which entered the order establishing the child support obligation, or the family support division, as applicable, stating that the child is emancipated and the statement is served by the court on the child support obligee.


  • when the court determines the amount owed by a parent for support provided to a child by another person, other than a parent, prior to the date of filing of a petition requesting support, or when the director of the family support division establishes the amount of state debt due, the court will use the guidelines established.




Upon requiring showing substantial and continuing change in circumstances, the court can modify a support order according to the state child support guidelines and any regulations if the amount in the current order differs from the amount which would be ordered according to child support guidelines.


Missouri Child Support Calculation Formula Methods

Child support can be arranged out of court by a mutual support agreement between the parents, or can be decided in Missouri family court through a child support order. In Missouri, a number of factors are taken into account when determining the amount of child support to be paid in court. Here is an explanation of the two most common methods used to calculate basic child support amounts.

Income Share Method

Under the income share model, the court uses economic tables to estimate the total monthly cost of raising the children. The non-custodial parent pays a percentage of the calculated cost that is based on their proportional share of both parents' combined income.

Example: The non-custodial parent of one child has an income of $2,000 per month, and the custodial parent has an income of $1,000 per month. The court estimates that the cost of raising one child is $1,000 a month. The non-custodial parent's income is 66.6% of the parent's total combined income. Therefore, the non-custodial parent pays $666 per month in child support, or 66.6% of the total child support obligation.

Missouri does use the income share method to calculate child support

Percentage Of Income Method

This method of calculating child support is simple - a set percentage of the non-custodial parent's income is paid monthly to the custodial parent to cover basic child support expenses. The percentage paid may stay the same, or vary if the non-custodial parent's income changes.

Example: The non-custodial parent of one child has an income of $2,000 per month. The court orders a flat percentage of 25% of the non-custodial parent's income to be paid in child support to the custodial parent. Therefore, the non-custodial parent pays $500 per month in child support. If the non-custodial parent's monthly income changes, the dollar amount they pay in child support will change as well.

Missouri does not use the percentage of income method to calculate child support

Missouri Child Support Frequently Asked Questions


How does having shared custody of the child affect child support in Missouri?

All states have a method of modifying the amount of child support owed in cases where the custody agreement provides for joint or shared custody of a child between both parents.

Missouri law allows the judge overseeing the child support order to use a shared custody agreement as justification for a variation from the state's general child support calculations. This means that if the non-custodial parent shares parenting time with the custodial parent, the judge might reduce the amount of child support owed to account for the resources spent by the non-custodial parent during their time with the child.


How are extraordinary medical costs treated by child support in Missouri?

Missouri has specialized guidelines for the sharing of a child's extraordinary medical care costs that are separate from, and in addition to, basic child support payments. Extraordinary medical costs are generally costs generated by things such as illness, hospital visits, or costly procedures such as getting braces.


How are child care costs treated by child support in Missouri?

Due to the high costs of child care for a single payment, Missouri has specialized guidelines that consider child care costs separately from the general costs of raising a child for the purposes of calculating child support payments.


Does child support cover college education expenses in Missouri?

Missouri state law does allow courts to order the non-custodial parent to contribute to their child's college education upon graduating high school. Whether post-secondary education support is ordered, and the amount that may be ordered, varies depending on the situation.


How is child support enforced in Missouri?

In the state of Missouri, child support is enforced by the state child support agency. The state agency handles the location of non-custodial parents, enforcement of support orders, and the handling of unpaid child support arrears.


What are child support arrears?

Child support arrears are the amount of child support that is delinquent, or unpaid, by the noncustodial parent to the custodial parent. Child support arrears may be collected by the state through wage garnishment, bank levy. withholding of Missouri welfare benefits, or other collection methods.


How are child support payments taxed in Missouri?

Under IRS guidelines, the recepient of child support does not need to pay federal tax on child support payments, and the payer of child support cannot deduct their child support payments. This differs from the federal taxation of alimony payments, which are treated as taxable income by the receiver and are deductible by the payor. Missouri tax law may vary on tax treatment of child support.
