How Missouri Child Support Payments Work and What Happens If You Fall Behind
What Missouri child support is and how the state collects it
Missouri child support is a court-ordered payment from one parent to the other, intended to cover a child's living expenses. The state does not decide the amount — a judge does, based on both parents' income, custody arrangement, and the child's needs. Once ordered, Missouri's Family Support Division (part of the Department of Social Services) takes over collection and payment processing, even if both parents agree on the amount.
Payments flow through the state's payment system, not directly between parents. This means the paying parent sends money to Missouri's centralized collection unit, which then distributes it to the receiving parent or, if the receiving parent is on public assistance, to the state first. The state keeps a portion to reimburse itself for benefits paid.
The payment method depends on your situation. Most payments are collected through wage withholding — the court orders your employer to deduct child support directly from your paycheck before you see it. If you are self-employed or your employer does not comply, you can pay by check, money order, or electronic transfer to the state's collection account. Some parents set up automatic bank transfers.
Key Takeaways
- Missouri's Family Support Division collects and distributes all child support payments, even if parents agree on the amount.
- Wage withholding is the most common collection method and happens automatically once a court order is in place.
- If you fall behind on payments, the state can intercept tax refunds, suspend your driver's license, and report the debt to credit bureaus.
- You can request a modification of the payment amount if your income has changed significantly, but you must file the request with the court.
- If you cannot pay, contact the Family Support Division to discuss payment plans or hardship options rather than ignoring the debt.
How much you owe and where the money goes
The judge sets the payment amount based on Missouri's child support guidelines, which use a formula tied to both parents' gross income. The guidelines assume a certain percentage of income goes to child support — roughly 20% for one child, 25% for two, 32% for three, and higher percentages for more children. However, judges can deviate from this if circumstances warrant it, such as if one parent has significant debt or unusual expenses.
Once you pay, the state takes its cut first. If the receiving parent is on Temporary Assistance (TANF), Supplemental Nutrition Assistance (SNAP), or Medicaid, Missouri keeps the first $50 of each month's payment to reimburse the state for benefits. After that, the remainder goes to the receiving parent. If the receiving parent is not on public assistance, you pay the full amount and it all goes to them, minus a small processing fee in some cases.
Your payment obligation continues until the child turns 18, or 19 if they are still in high school. If you have multiple children with the same parent, the obligation typically ends for each child on their individual birthday, reducing your monthly payment at each step.
What happens if you miss a payment or fall behind
Missouri treats unpaid child support as a debt to the state, not just a private matter between parents. If you miss a payment, the state's collection system flags the account. After 30 days, the debt is reported to credit bureaus, which damages your credit score. After 60 days, the state can begin enforcement actions.
The most common enforcement tools are tax refund interception and driver's license suspension. The state automatically intercepts your federal and state income tax refunds and applies them to your arrears. Your driver's license can be suspended if you owe more than one month's payment or if you have failed to pay for 30 days after a court hearing. A suspended license makes it illegal to drive and can result in criminal charges if you are caught.
The state can also place a lien on your property, garnish your wages beyond the original withholding order, suspend your professional licenses (such as a nursing or contractor's license), and report you to the Missouri Case Registry, which is a public record. In cases of willful non-payment, the state can pursue contempt of court charges, which can result in jail time.
Modifying your payment amount if your income changes
If your income has dropped significantly — due to job loss, illness, or a major reduction in hours — you can request that the court lower your payment amount. This is called a modification. You must file a motion with the court that issued the original order; simply telling the Family Support Division or the receiving parent will not change your legal obligation.
To file a modification, contact the circuit court in the county where the order was issued and ask for the forms to request a modification of child support. You will need to provide recent pay stubs, tax returns, or other proof of your current income. There is a filing fee, though you may be able to request a fee waiver if you cannot afford it. The court will schedule a hearing, and both parents will have a chance to present their case.
Important: if you stop paying while waiting for a modification hearing, you will still owe all the back payments, and the state will continue enforcement. File the modification request as soon as your income changes, not after you have missed payments.
Payment plans and hardship options
If you are unable to pay the full amount but want to avoid enforcement, contact the Missouri Family Support Division directly. You can negotiate a payment plan — an agreement to pay a smaller amount each month until you catch up on arrears. Payment plans are not automatic; you must request one and the state must agree. The plan will be documented, and if you stick to it, the state typically will not pursue other enforcement actions while you are in compliance.
If you are facing a temporary hardship — such as a brief period of unemployment or an unexpected medical expense — explain this when you contact the Division. They cannot forgive the debt, but they can pause enforcement temporarily or adjust the payment schedule. Some parents have also had success requesting a temporary reduction in the payment amount through the court, even without a full modification hearing, if the hardship is documented and time-limited.
The Family Support Division's phone number is 573-751-4301. Have your case number ready when you call. You can also visit their office in person in Jefferson City or contact your local circuit court's family support office.
How to make a payment or set up automatic payments
If you are not on wage withholding, you need to send your payment to Missouri's centralized collection unit. Payments can be made by check or money order mailed to the address on your court order, or by electronic transfer through the state's online payment system. Some employers offer payroll deduction options even without wage withholding; ask your payroll department if this is available.
To set up automatic payments, contact the Family Support Division or visit the Missouri Department of Social Services website. You can authorize a monthly bank transfer from your account to the state's collection account. This ensures you never miss a payment and creates a record of on-time payment, which can help if you later dispute arrears or request a modification.
Keep records of every payment you make. If you pay by check, keep the cancelled check or bank statement. If you pay electronically, print or save the confirmation. These records protect you if there is ever a dispute about whether a payment was received.
Understanding arrears and how they accumulate
Arrears are the total amount of child support you owe but have not paid. They accumulate daily at the rate of your monthly obligation divided by the number of days in the month. For example, if you owe $500 per month and miss one month, you owe $500 in arrears. If you miss three months, you owe $1,500, plus any interest or penalties the state has added.
Missouri does not charge interest on child support arrears in most cases, but the state does add a $25 monthly collection fee if you are behind. This fee compounds, so the longer you go without paying, the more you owe beyond the base child support amount. Additionally, if you owe more than $150 in arrears, the state can report you to the Missouri Case Registry, which is a public record that can affect your reputation and employment prospects.
Arrears do not disappear. Even if the child turns 18 and your regular payment obligation ends, you still owe all the back payments. The state can pursue collection for years, and arrears can follow you if you move to another state — Missouri has reciprocal agreements with other states to enforce child support orders.
Frequently Asked Questions
Can I stop paying child support if I lose my job?
No, but you should file a modification request immediately. Your obligation continues until the court changes it. If you stop paying without filing a modification, you will owe arrears and face enforcement. Contact the Family Support Division or your local court to start the modification process as soon as you lose income.
What if the receiving parent and I agree to stop child support payments?
A private agreement between you and the other parent does not change your legal obligation. Only a court can modify or terminate a child support order. If you both want to end payments, you must file a joint motion with the court. If you pay based on a private agreement instead of the court order, you are still technically in violation, and the state can pursue enforcement.
Will my child support payment go down if I get custody?
It may, depending on the new custody arrangement. If you gain primary custody, your payment obligation typically decreases or ends. You must file a modification request with the court and provide proof of the custody change. The judge will recalculate based on the new arrangement and both parents' current income.
Can I go to jail for owing child support?
Yes, if the court finds you in contempt — meaning you willfully refused to pay despite having the ability to do so. Jail is typically a last resort after other enforcement methods have failed, but it is possible. If you are struggling to pay, contact the Family Support Division before enforcement reaches that stage.
How do I find out how much I owe in arrears?
Contact the Missouri Family Support Division at 573-751-4301 or visit your local circuit court's family support office. You can also request a statement of arrears in writing. The state will provide a detailed breakdown of what you owe, including the base child support amount, any collection fees, and the date through which the arrears have been calculated.
