Ohio Child Support Laws & Guidelines
Child support in Ohio is calculated using statutory guidelines designed to ensure both parents contribute to a child’s financial needs. Primary authority is found in Chapter 3119 of the Ohio Revised Code and related administrative rules.
Guidelines consider gross income, parenting time arrangements, health insurance costs, childcare expenses, and other factors listed on the official child support worksheet. Courts may deviate from the guideline amount when circumstances warrant.

Chapter 3119
How Ohio Calculates Child Support
Ohio’s child support schedule and worksheet translate parental income and other financial factors into a guideline support amount. Accurate income disclosure — including wages, bonuses, self-employment income, and certain benefits — is essential.
Parenting time adjustments may reduce or modify the basic obligation when a parent has substantial overnight time with the child. Health insurance premiums and extraordinary medical expenses may also affect the calculation.
