Child Support Calculator in Ohio: What You Should Know

Ohio uses the Income Shares Model applied to gross income, with specific deductions for taxes, local income taxes, union dues, and other mandatory deductions built into the guideline worksheet. Ohio updated its guidelines in 2019, adjusting the income tables and introducing a more refined parenting time adjustment schedule. The 2019 update also changed how self-employment income is calculated. Self-employed parents now use actual business income after ordinary and necessary business expenses, rather than gross business revenue. Ohio has no hard income cap, but courts have discretion to deviate from the guideline in high-income cases.

Child Support in Ohio - Frequently Asked Questions

How is child support calculated in Ohio?

Ohio uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.

Can child support be modified in Ohio?

Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in Ohio typically require a change of at least 15-20% in the support amount to justify modification.

Does custody arrangement affect child support in Ohio?

Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.

Is there an income cap for child support in Ohio?

Ohio does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.

How long does child support last in Ohio?

Child support in Ohio typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
