Support in Ohio (2026)

Ohio’s Child Support Computation Worksheet

Ohio’s child support system revolves around a structured computation worksheet that courts and the Child Support Enforcement Agency (CSEA) use to calculate every child support order. Understanding how this worksheet operates is essential for any parent facing a support determination.

The worksheet, prescribed by ORC § 3119.022, follows a step-by-step process. It begins with each parent’s gross income, which includes wages, salaries, commissions, bonuses, overtime, self-employment income, rental income, retirement benefits, and most other income sources. The court may impute income to a parent who is voluntarily unemployed or underemployed. From gross income, the worksheet subtracts certain mandatory deductions — including local income taxes, mandatory retirement contributions, and existing support obligations for other children — to arrive at each parent’s adjusted gross income.

The two adjusted gross incomes are combined to produce a combined gross income figure. That figure is then matched to the basic child support schedule in ORC § 3119.021, which is a statutory table that specifies a dollar amount of support based on the combined income level and the number of children. Each parent’s share of the obligation is proportional to their percentage of the combined gross income. For example, if one parent earns 60% of the combined income, they are responsible for 60% of the basic obligation.

The worksheet then applies adjustments for health insurance premiums paid on behalf of the child, work-related childcare expenses, and cash medical support for uninsured medical costs. The result is the final child support order amount, which the obligor parent (typically the parent with less parenting time) pays to the obligee parent through the Ohio Child Support Payment Central (OCSPC).

This worksheet-driven approach provides transparency and consistency, but it does not account for every family situation — which is why Ohio law also provides for deviations.

Overview of Ohio Support Law

Ohio uses the income shares model for child support, meaning both parents’ incomes factor into the calculation. The governing statutes are found in Ohio Revised Code §§ 3119.01 through 3119.99, which lay out the child support schedule, computation worksheet, and rules for deviation. Spousal support (Ohio’s term for alimony) is addressed separately under Ohio Revised Code § 3105.18 and is left largely to the court’s discretion. There is no statutory formula for spousal support in Ohio.

These two forms of financial support serve different purposes, but they often intersect during divorce proceedings. Understanding how each works can help you prepare for what lies ahead.

How Child Support Is Calculated

Ohio’s child support computation starts with determining each parent’s gross income. Gross income includes wages, salaries, commissions, bonuses, overtime, self-employment income, rental income, retirement benefits, and most other sources of income. The court may also impute income to a parent who is voluntarily unemployed or underemployed.

Once each parent’s gross income is established, the court combines them to produce a combined gross income figure. That figure is then applied to the basic child support schedule found in Ohio Revised Code § 3119.021, which specifies a base support obligation depending on the combined income and the number of children.

Each parent’s share of the obligation is proportional to their share of the combined gross income. The court then adjusts the base obligation for:

• Health insurance costs for the child
• Work-related childcare expenses
• The local self-sufficiency reserve, which ensures the obligor parent retains enough income to meet basic living needs
• Cash medical support for uninsured medical expenses

The obligor parent (typically the parent with less parenting time) pays their share to the obligee parent. For a broader explanation of income shares calculations, see our guide on how child support is calculated.

Key Factors and Deviations

Ohio courts can deviate from the calculated guideline amount when the standard calculation would be unjust or inappropriate. Under Ohio Revised Code § 3119.23, the court considers the following deviation factors:

• Special or unusual needs of the child
• Extraordinary obligations for either parent, such as court-ordered support for other children
• Extended parenting time or other extraordinary costs associated with visitation
• The obligor’s net income and ability to pay
• The standard of living the child would have enjoyed had the marriage continued
• The physical and emotional condition of the child
• The educational needs and opportunities of the child
• The financial resources and earning ability of the child
• The relative financial resources and needs of each parent
• Whether either parent has a prior support obligation that is being paid

Any deviation must be accompanied by written findings explaining why the guideline amount is unjust and why the deviated amount is appropriate.

Modifying Child Support

Either parent can seek a modification of child support by demonstrating a change in circumstances. Ohio law also provides for administrative reviews. The Child Support Enforcement Agency (CSEA) will review an order every 36 months upon request by either parent. If the recalculated amount differs from the current order by 10 percent or more, the CSEA will recommend a modification.

Common grounds for modification include:

• A substantial change in either parent’s income (increase or decrease)
• A change in the child’s needs
• A change in the parenting time arrangement
• A change in the cost of health insurance or childcare
• A child aging out of support (in Ohio, child support generally continues until the child turns 18, or 19 if still attending high school)

Enforcing Child Support

Ohio enforces child support through the CSEA and the Office of Child Support within the Ohio Department of Job and Family Services. Enforcement tools include income withholding orders (wage garnishment), interception of federal and state tax refunds, suspension of driver’s licenses and professional licenses, passport denial, liens on property, and contempt of court proceedings. Ohio is among the more aggressive states in pursuing non-payment.

Spousal Support in Ohio

Ohio uses the term “spousal support” rather than alimony. Unlike child support, there is no formula or guideline schedule for spousal support. Courts have broad discretion to determine whether spousal support is appropriate, and if so, the amount and duration. Some county courts use informal benchmarks or local guidelines, but these are not binding.

Spousal support can be awarded as part of a divorce, dissolution, or legal separation. It may be temporary (during the proceedings) or long-term (as part of the final decree).

Factors the Court Considers for Spousal Support

Under Ohio Revised Code § 3105.18(C)(1), the court must consider the following factors when making a spousal support determination:

• The income and earning ability of each spouse
• The ages and physical, mental, and emotional conditions of both spouses
• The retirement benefits of each spouse
• The duration of the marriage
• The extent to which it would be inappropriate for a spouse who is custodial parent to seek employment outside the home
• The standard of living established during the marriage
• The relative extent of education of each spouse
• The relative assets and liabilities of each spouse, including court-ordered payments
• The contribution of each spouse to the education, training, or earning ability of the other
• The time and expense necessary for the requesting spouse to acquire education, training, or experience to obtain appropriate employment
• The tax consequences of spousal support for each party
• The lost income production capacity of either party resulting from marital responsibilities
• Any other factor the court finds relevant and equitable

Ohio courts commonly consider the length of the marriage as a rough guide to duration. In marriages under 10 years, spousal support is often limited. In marriages of 20 years or more, longer-term awards are more common. But there are no hard rules — every case depends on its facts.

Modifying Spousal Support

Whether spousal support can be modified depends on the terms of the original order. If the divorce decree or separation agreement states that spousal support is non-modifiable, neither party can request a change. If the order does not include such a restriction, either party may petition for modification based on a change in circumstances.

Courts may also terminate spousal support upon the death of either party, the remarriage of the recipient, or cohabitation of the recipient with another person in a relationship analogous to marriage. However, cohabitation is not an automatic termination trigger — the paying spouse must file a motion and prove the cohabitation.

When to Seek Legal Help

Ohio’s child support guidelines provide structure, but spousal support remains highly discretionary. The difference between a well-prepared case and a poorly prepared one can be significant in dollar terms. Whether you expect to pay or receive support, understanding the statutory factors and how Ohio courts apply them in practice is essential.

Frequently Asked Questions

What child support model does Ohio use?

Ohio uses an income shares model under Ohio Revised Code Sections 3119.01 through 3119.99. Both parents’ gross incomes are combined and applied to the basic child support schedule in Section 3119.021. Each parent’s share is proportional to their percentage of the combined gross income.

How does Ohio’s child support computation worksheet work?

The worksheet prescribed by ORC § 3119.022 starts with each parent’s gross income, subtracts mandatory deductions (local taxes, retirement contributions, and existing support obligations), combines the adjusted incomes, and matches the total to the basic child support schedule table. Each parent’s share is proportional to their percentage of the combined income. The worksheet then adjusts for health insurance, childcare, and cash medical support to produce the final order amount.

Until what age does child support last in Ohio?

Child support in Ohio generally continues until the child turns 18, or 19 if the child is still attending high school. The Child Support Enforcement Agency (CSEA) will review an order every 36 months upon request, and if the recalculated amount differs by 10% or more, a modification may be recommended.

Does Ohio use a formula for spousal support?

No. Ohio has no formula or guideline schedule for spousal support. Under Ohio Revised Code Section 3105.18, courts have broad discretion, considering 14 statutory factors including income, earning ability, ages, duration of the marriage, and standard of living. Some county courts use informal benchmarks, but these are not binding.

What term does Ohio use for alimony?

Ohio uses the term “spousal support” rather than alimony. Spousal support can be awarded as part of a divorce, dissolution, or legal separation, and may be temporary or long-term. Whether it can be modified depends on the terms of the original order — if marked non-modifiable, neither party can request a change.
