Back child support in Ohio is past-due support that a parent failed to pay under a valid court or administrative order, governed by Ohio Revised Code Chapters 3119, 3121, and 3123. As of 2026, Ohio courts assess 7% annual interest on willful arrears reduced to judgment, intercept tax refunds when past-due support reaches $150, and can suspend licenses, deny passports above $2,500, and pursue contempt or felony non-support. Ohio has no statute of limitations on collecting child support arrears.

What Counts as Back Child Support in Ohio?
Back child support in Ohio is the unpaid balance of a court-ordered or administrative support obligation, plus any interest assessed by the court. Under Ohio Rev. Code Ch. 3123, a parent (the obligor) is legally in default after falling one full month behind. The unpaid total is called an arrearage, and Ohio treats it as a money judgment that cannot be retroactively reduced or eliminated.
Past due child support in Ohio differs from a current monthly obligation because arrears survive even after the child turns 18 or the case otherwise closes. Ohio child support arrears remain a legal debt until satisfied in full, including any portion owed to the state for public assistance reimbursement. When child support arrears are owed to both the family and the Ohio Department of Job and Family Services, payments are allocated under Ohio Rev. Code § 3123.19 in accordance with Title IV-D of the Social Security Act, 42 U.S.C. 651. Federal tax intercept dollars are applied first to any arrears owed to the State of Ohio when public assistance reimbursement is outstanding.
How Does Ohio Calculate Interest on Child Support Arrears?
Ohio assesses 7% annual interest on child support arrears in 2026, but only when the court finds the non-payment was willful and the arrears have been reduced to a judgment. The rate is set by Ohio Rev. Code § 1343.03 and adjusts each year; the Ohio Tax Commissioner fixed the 2026 judgment rate at 7%, down from 8% in 2024 and 2025.
Interest does not automatically attach to every past-due child support balance. Under Ohio Rev. Code § 3123.17, a court shall assess interest on support an obligor failed to pay if it determines the failure was willful and the arrears accrued after July 15, 1992. The obligee typically must file a motion for a lump-sum judgment, after which interest accrues from the date the judgment is rendered, unless the court finds it would be inequitable to assess interest. The rate stated in the judgment entry is locked in for the life of the judgment under Ohio Rev. Code § 1343.03(B), meaning a 7% rate set in 2026 continues at 7% even if the statutory rate later changes. This makes early resolution of child support debt financially significant for obligors.
How Ohio Enforces Back Child Support
Ohio enforces back child support through county Child Support Enforcement Agencies (CSEAs), which deploy administrative and judicial tools under Ohio Rev. Code Ch. 3123. When an obligor falls one month behind, the CSEA issues a default notice and reports the obligor to the credit bureau. The Ohio Department of Job and Family Services oversees the statewide IV-D program, but each of Ohio's 88 counties operates its own CSEA.
Enforcement escalates with the size and age of the child support debt. Income withholding under Ohio Rev. Code § 3121.03 is the primary tool, deducting support directly from wages and other income. Beyond wage withholding, a CSEA may place liens on real and personal property under Ohio Rev. Code § 3123.67, seize funds from financial accounts, attach retirement and pension funds, report the obligor to credit bureaus, and require an unemployed obligor to seek work. The default-notice process is detailed in Ohio Rev. Code § 3123.03, which requires the agency to send written notice; if the obligor does not request a hearing within the stated period, the notice becomes a final determination of the arrearage. These layered enforcement actions continue indefinitely because Ohio recognizes no statute of limitations on collecting past due child support.
Tax Refund Intercept for Ohio Child Support Debt
Ohio automatically intercepts state and federal tax refunds once past-due child support reaches $150. When this threshold is met, the case is submitted to the Ohio Department of Taxation and, where federal criteria are satisfied, to the Internal Revenue Service. Intercepted refunds are forwarded to the CSEA and applied to the obligor's child support arrears.
The $150 threshold is notably low and triggers automatic submission without a separate court order. Federal tax intercept payments are applied first to any arrears owed to the State of Ohio when public assistance reimbursement is outstanding, before family-owed arrears are paid. For obligors with a current spouse, the non-obligated spouse may file an injured-spouse claim with the IRS to recover their share of a jointly filed federal refund. Tax intercept is one of the most common enforcement mechanisms because it operates automatically through data matching rather than requiring agency staff to initiate individual actions. Importantly, intercepted tax refund dollars do not count toward the 50% payment requirement that the obligor must meet to avoid license suspension, so receiving a tax offset alone will not shield an obligor from losing their driver's, professional, or recreational license.
License Suspension for Unpaid Child Support in Ohio
Ohio can suspend an obligor's driver's, professional, and recreational licenses when they pay less than 50% of their child support obligation for 90 consecutive days. Before suspending, the CSEA must send a pre-suspension notice to the obligor's last known address and allow 10 days to contact the agency and arrange payment to avoid the suspension.
License suspension in Ohio reaches far beyond driving privileges. A notice to suspend may be sent to every licensing board in Ohio with authority over the obligor, blocking issuance, renewal, and reinstatement of professional licenses (such as nursing, law, or contractor licenses) and recreational licenses (such as hunting and fishing). No board may reinstate a suspended license until the CSEA issues a release. To restore a suspended driver's license after the CSEA releases the hold, the obligor must apply for reinstatement at one of seven Ohio BMV branches offering this service and satisfy all other reinstatement requirements, including proof of insurance and clearing any out-of-state suspensions. Because tax intercept payments do not count toward the 50% threshold, obligors who owe back child support in Ohio must make voluntary or withheld payments to protect their licenses.
Passport Denial and Property Liens
Ohio refers obligors to the U.S. State Department for passport denial when past-due child support exceeds $2,500, and the State Department refuses to issue or renew a passport until the CSEA confirms the debt has been satisfied. This federal enforcement tool applies to the aggregate arrearage across all of an obligor's Ohio cases.
Property enforcement gives the CSEA powerful leverage over assets. Under Ohio Rev. Code § 3123.67, an unpaid child support arrearage becomes a lien against the obligor's real and personal property, which can prevent the sale or refinancing of a home until the support debt is paid. The CSEA may also reach claims the obligor holds against third parties: under Ohio Rev. Code § 3123.19, an obligor in default who has a claim against another person exceeding $1,000 must notify the CSEA of the claim, its nature, and the name of the person against whom it exists. Additional collection authority appears in Ohio Rev. Code § 3123.22 and § 3123.23, allowing the agency to pursue arrearages from collateral sources such as lottery winnings, workers' compensation awards, and unemployment benefits.
Contempt of Court and Criminal Non-Support
Ohio can hold a non-paying parent in contempt of court, and a first finding of contempt may result in up to 30 days in jail plus court costs, with subsequent findings carrying jail terms of roughly 30 to 90 days. Severe cases can escalate to felony criminal non-support under Ohio Rev. Code § 2919.21, which carries potential prison time of up to five years.
Civil contempt is purpose-driven: judges typically allow the obligor to purge the contempt by paying a lump sum toward the child support debt, and incarceration is generally a last resort after the CSEA investigates the reasons for non-payment. Criminal non-support applies when a parent fails to provide support for 26 weeks within a two-year period, and that conduct can be charged as a felony. Federal law adds an interstate dimension: Ohio CSEAs must pursue criminal non-support when support is unpaid for at least a year, the arrears exceed $5,000, and the parent and child live in different states. Even after a criminal conviction, the obligor still owes every dollar of unpaid child support — a contempt or criminal sanction punishes the non-payment but never discharges the underlying child support debt.
Can You Reduce or Eliminate Back Child Support in Ohio?
Ohio courts cannot retroactively reduce or eliminate child support arrears, because past-due support is treated as a fixed money judgment. A modification of a support order under Ohio Rev. Code § 3119.79 only changes the obligation going forward from the date the modification motion was filed — it never erases arrears that have already accrued.
There are limited, lawful pathways to address a back child support balance. The obligee can voluntarily agree to forgive or compromise arrears owed to the family, and Ohio participates in debt compromise programs for arrears owed to the State (typically tied to past public assistance). An obligor who believes the calculated arrearage is wrong may request an administrative or judicial hearing during the default-notice process under Ohio Rev. Code § 3123.032 before the determination becomes final. An obligor facing genuine inability to pay should proactively contact the CSEA, because the agency investigates reasons for non-payment such as job loss or illness and will work with parties acting in good faith. The safest strategy for managing child support debt in Ohio is to seek a prospective modification immediately when income drops, rather than letting arrears accumulate while waiting for relief.
How to Pay Off Past Due Child Support in Ohio
Obligors pay off past due child support in Ohio through their county CSEA, which applies payments to current support first and then to arrears unless a court orders otherwise. Under Ohio Rev. Code § 3123.21, a presumed minimum payment on arrears is added to support orders, structuring how quickly the child support debt is repaid.
Payment methods include automatic income withholding, the Ohio Child Support Payment Central system, online payment portals, and direct payments to the CSEA. When arrears are owed to multiple parties, allocation follows Ohio Rev. Code § 3123.19 and Title IV-D rules, with state-owed balances often satisfied before family-owed balances and federal tax intercepts applied first to state arrears. Obligors who want to accelerate repayment and stop the accrual of 7% interest can make lump-sum payments or negotiate a structured payment plan with the CSEA. Because each Ohio county operates its own enforcement agency, obligors should confirm the exact balance, interest assessed, and accepted payment methods directly with their local CSEA, which can be located through the Ohio Department of Job and Family Services county directory.
