Missouri uses Form No. 14
The worksheet combines adjusted monthly gross income, selects the closest schedule row, allocates basic and additional child costs by income share, and credits qualifying payer expenses.
Line 11 applies a published overnight adjustment, with court-controlled treatment above 109 overnights and self-support restrictions.
Worked example: two children
- Add both adjusted monthly incomes.
- Select the closest row and two-child amount.
- Allocate costs by income share, subtract payer-paid costs, then apply the qualifying overnight adjustment.

Does an overnight credit begin immediately?
No. The published table starts at 36 overnights with 6%.
