How Missouri child support law works
Legal starting point. Missouri uses Supreme Court Form 14 as the child-support calculation framework. The form produces a presumed child-support amount, but the court can consider the form’s adjustments and statutory deviation factors before entering an order. Read Missouri Supreme Court Form 14 and directions.
How the guideline is calculated
Form 14 combines the parents’ adjusted monthly gross income, takes the basic amount from the current schedule, and allocates it by proportional income share. Child care, insurance, tax credit, extraordinary costs, overnight adjustments, and other-child credits require the complete form.
What this site’s worksheet covers
Uses the 2024 Child Support Guideline Review updated schedule attached to the Missouri Supreme Court Form No. 14 order effective January 1, 2026. Form No. 14 uses each parent’s adjusted monthly gross income for support, their proportionate share, and the schedule basic support amount for the number of children. This base module uses the next encoded schedule row at or above combined adjusted monthly gross income. The schedule stops at $40,000; above that row it shows no amount. Work-related child care, federal child-care tax credit, health insurance, uninsured medical costs, extraordinary child-rearing costs, overnight adjustment, other-child credits and deviations require the full Missouri Form No. 14 worksheet.

Before you enter your numbers
What is Missouri Form 14's overnight adjustment for?
Form 14 includes an adjustment for overnight custody or visitation as part of the presumed-support calculation. Its instructions govern when and how the adjustment applies. It is separate from the basic schedule lookup and from the amounts credited for child care or health coverage.
Prepare this: Use the current Form 14 instructions with the overnight calendar and itemized child expenses. Keep a copy of the completed lines so a reviewer can see the reason for each adjustment.
Read the relevant official instructions: Missouri Supreme Court: Form 14 and directions; Missouri Courts: Form 14 worksheet, lines 10 and 11.
These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.
How Missouri cases actually get to a number
Form 14 combines adjusted monthly gross income, takes the basic amount from the schedule, and allocates by proportional share. Line items for child care, insurance, overnight adjustments, and other-child credits are easy to skip and expensive to skip.
Missouri Supreme Court Form 14 produces a presumed child-support amount from combined adjusted monthly gross income and the current schedule. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.
Parenting time in Missouri
Overnight adjustments on Form 14 are line-item math, not a new schedule. Split custody and alternating weeks still have to match the form’s definitions.
Costs Missouri usually treats separately
- Work-related child-care costs
- Health-insurance costs
- Extraordinary medical and educational costs
- Other-child credits
When Missouri courts leave the guideline
After Form 14 is complete, the court may consider rebuttal factors. Completing the form incorrectly is not a deviation; it is just an incorrect presumed amount.
