Ohio Statutory Child Support Calculator

Ohio calculates child support pursuant to Ohio Revised Code § 3119.01 using the Income Shares Model. Under R.C. § 3119.051, when a parent exercises court-ordered parenting time equal to or exceeding 90 overnights per year, the court must reduce that parent’s annual child support obligation by an automatic 10% statutory credit. If parenting time reaches 147+ overnights, courts may award additional deviations. Official statutory authority: Ohio Rev. Code § 3119.01 et seq..

Ohio Legal Mechanics & Court Standards

Legislative Formula & Terminology

Combined gross incomes determine basic support from the ODJFS schedule table. Each parent pays their pro-rata income share. Parents with 90+ overnights receive an automatic 10% reduction under R.C. § 3119.051, and 50/50 shared parenting triggers reciprocal offset.

Ohio Custody Schedules, High-Income Caps & Precedent

How Ohio family courts apply Ohio Rev. Code § 3119.01 et seq. across 50/50 equal parenting schedules, high-net-worth income deviations, and traditional sole physical custody orders:

Equal Parenting Time

Ohio: 50/50 Shared Custody

Load 50/50 Shared Custody Preset ↑

Statutory Rule: Under R.C. § 3119.051, 50/50 custody triggers reciprocal cross-credit offset on Form JFS 07768, plus the statutory 10% parenting time credit.

Key Statutory Rules

  • Ohio applies reciprocal cross-credit calculations on Form JFS 07768 for equal 50/50 shared parenting schedules.
  • Under R.C. § 3119.051, the 10% statutory parenting time credit is applied directly to reduce the higher earner’s net support order.
  • Courts consider whether shared parenting plans truly duplicate living expenses before granting supplemental deviations.
  • Health insurance and cash medical support remain allocated pro-rata based on gross income shares.

Judicial Application & Controlling Case Law

Ohio Common Pleas judges enforce Form JFS 07768 and statutory 10% credits under R.C. § 3119.051.

Controlling Authority: Pauly v. Pauly, 80 Ohio St. 3d 386 (1997); R.C. § 3119.051.

Practical Calculation Benchmark

Parent A earning $6,000/mo and Parent B earning $4,000/mo with 2 children results in Parent A paying approximately $378/month after 10% credit.

Cap Deviation Analysis

Ohio: High-Income Deviation

Load High-Income Deviation Preset ↑

Statutory Rule: R.C. § 3119.04 caps combined gross income at $336,400/yr ($28,033/mo). Above this, courts award the guideline maximum plus case-by-case supplemental needs.

Key Statutory Rules

  • Under R.C. § 3119.04, when combined gross income exceeds $336,400/year ($28,033/month), the schedule table reaches its statutory ceiling.
  • The court orders the maximum guideline amount as a baseline ($3,850/month for 2 children) and evaluates qualitative needs for supplemental support.
  • Courts review whether high expenses are reasonable in light of the parents’ wealth without awarding a disguised windfall to the residential parent.
  • High-income parents are required to fund children’s college trusts or private preparatory education directly.

Judicial Application & Controlling Case Law

Ohio judges refuse to mechanically extrapolate table percentages into high-earner brackets, prioritizing documented needs.

Controlling Authority: Siegel v. Siegel, 2021-Ohio-1811; R.C. § 3119.04.

Practical Calculation Benchmark

On combined gross income of $50,000/month, the court orders base support on $28,033 ($3,850/mo) plus direct payment of $3,000/mo tuition.

Primary Custodian Baseline

Ohio: Sole Custody Guidelines

Load Sole Custody Guidelines Preset ↑

Statutory Rule: Standard sole residential parent calculation applies on Form JFS 07768; no 10% credit applies if overnights are under 90.

Key Statutory Rules

  • In traditional sole residential parent situations where the non-residential parent has under 90 overnights, Form JFS 07768 applies without parenting credits.
  • The obligor pays their full pro-rata percentage of the ODJFS schedule table.
  • The obligor is protected by the Ohio self-support reserve ($1,215/month) and statutory $80/month minimum order.
  • Direct expenses during visitation are not credited against court-ordered child support.

Judicial Application & Controlling Case Law

Ohio courts apply the basic child support schedule without modification when visitation does not reach 90 nights.

Controlling Authority: R.C. § 3119.01; Marker v. Grimm, 65 Ohio St. 3d 139 (1992).

Practical Calculation Benchmark

Non-residential parent earning $5,000/mo gross where residential parent earns $3,000/mo (62.5% share) pays $1,125/month for 2 children.

Statutory Adjustment Guide

Allowable Income Deductions in Ohio

Ohio calculates child support from Gross Income on Form JFS 07768 under R.C. § 3119.01. While federal and state income taxes are already factored into the ODJFS economic tables, Ohio law permits specific statutory adjustments for municipal/local income taxes, self-employment FICA, and prior support:

R.C. § 3119.01(C)(13)

Local Income Taxes Paid

Actual municipal or regional income taxes paid or withheld.

R.C. § 3119.01(C)(13)

FICA and Medicare Withholding

Mandatory Social Security and Medicare payroll tax contributions.

R.C. § 3119.01(C)(13)

Mandatory Union Dues

Union dues paid as a mandatory condition of active employment.

R.C. § 3119.05(B)

Court-Ordered Support for Other Children Paid

Pre-existing child support orders actively paid for other children.

Judicial Discretion

Grounds for Departure from Ohio Guideline Math

Under Ohio Rev. Code § 3119.22, a Common Pleas judge or magistrate may deviate from the Form JFS 07768 worksheet amount if, upon considering the 16 statutory factors in R.C. § 3119.23, the court enters journalized findings that the guideline amount would be unjust, inappropriate, and not in the child’s best interest:

⚖️ Parenting Time Credit (R.C. § 3119.051)

Mandatory 10% reduction for 90+ overnights; extended discretionary deviation for 147+ overnights.

⚖️ Special and Unusual Needs of Children (R.C. § 3119.23(A))

Significant medical, educational, or therapeutic costs exceeding standard guidelines.

⚖️ Extraordinary Travel Costs for Visitation (R.C. § 3119.23(D))

Substantial transportation and lodging expenses necessary to exercise scheduled parenting time.

⚖️ Disparity in Income and Earning Capacity (R.C. § 3119.23(G))

Substantial wealth or earning differential between households.

Mathematical Case Study

Ohio Income Shares Worked Example (2 Children, 100 Overnights)

Case Facts: Parent A earns $7,000/mo gross; Parent B earns $3,000/mo gross. Combined income is $10,000/mo. Parent A exercises 100 overnights (qualifying for the 90-night 10% credit under R.C. § 3119.051).
Step 1: Calculate Combined Gross Income$7,000 + $3,000 = $10,000/mo

Parent A represents 70.0% of combined income; Parent B represents 30.0%.

Step 2: Schedule Table Lookup$2,100 basic support

The ODJFS economic schedule sets basic family support at $2,100/mo for 2 children at $10,000 income.

Step 3: Prorate Obligor Share$2,100 × 70% = $1,470/mo

Parent A’s preliminary guideline obligation is 70% of $2,100.

Step 4: Apply 10% Parenting Time Credit$1,470 - ($1,470 × 10%) = $1,323/mo

Because Parent A has 100 overnights (≥ 90), R.C. § 3119.051 applies an automatic 10% discount (-$147).

💡 Calculated Judicial Order: Parent A pays $1,323/month in guideline child support to Parent B.
State Legal Questions

Ohio Child Support Guidelines FAQ

What is the 90-night parenting time credit in Ohio?

Under Ohio Revised Code § 3119.051, when a court issues a parenting time order granting an obligor 90 or more overnights per calendar year (approximately 25% of parenting time), the court is statutorily required to apply an automatic 10% reduction to the obligor’s annual child support obligation.

How does Ohio calculate child support in 50/50 shared parenting?

In equal 50/50 shared parenting plans (182.5 or 183 overnights), Ohio courts apply a reciprocal cross-credit calculation on Form JFS 07768. The basic obligation is computed for each parent based on their respective incomes, and the higher-earning parent pays the net difference minus the 10% statutory parenting credit.

How does Ohio handle parental income exceeding the $336,400 statutory cap?

Pursuant to R.C. § 3119.04, when combined gross income exceeds $336,400 annually ($28,033 monthly), the court determines child support on a case-by-case basis. The court orders the guideline maximum as a baseline and assesses the developmental and standard-of-living needs of the child to determine any supplemental support.

How are health insurance premiums credited on Ohio Form JFS 07768?

Under R.C. § 3119.05, the parent who provides health insurance coverage for the minor child receives a direct worksheet credit for the actual out-of-pocket marginal premium cost, apportioned between parents in proportion to their gross incomes.
