- High incomes: When combined income is above the basic schedule, support is set case by case but not less than the amount at the schedule's maximum income (ORC 3119.04).
- Shared parenting time: Support is reduced by 10 percent when court-ordered parenting time equals or exceeds 90 overnights a year (ORC 3119.051).
