Unpaid Child Support Statistics: Arrears, Collections, and Enforcement

Americans owe more than $115 billion in unpaid child support, and the latest unpaid child support statistics show that only about half of custodial parents with an order receive the full amount they are owed. In fiscal year 2024, the federal child support program distributed $28.6 billion to families, yet nearly one in four custodial parents with a support arrangement got nothing at all that year.

The National Arrears Total

Cumulative child support debt in the United States has passed $115 billion. That figure includes money owed directly to families and money owed to state governments that advanced public assistance when support went unpaid. When a family receives benefits like Temporary Assistance for Needy Families, the state can keep child support collections to reimburse itself, so a large share of the national total is technically owed to government agencies rather than to custodial parents.

In FY 2024, the federal child support program collected and distributed $29.5 billion in total, with $28.6 billion of that going to families. The program reported collections on 63% of cases with arrears, meaning more than a third of arrears cases saw zero recovery during the year.¹

Much of the stacked-up debt is functionally uncollectable. Many parents who owe large arrears have low incomes, are incarcerated, or have left the formal economy. When someone earning minimum wage owes $50,000 in back support, the balance exists on paper but has little realistic chance of being paid in full. The national arrears figure overstates what could reach families even under perfect enforcement.

How Many Custodial Parents Actually Get Paid

The Census Bureau’s 2022 report on custodial parents is the clearest national picture of who receives support and who doesn’t. About 49.5% of custodial parents who were supposed to receive child support got the full amount.² That’s the highest figure in recent surveys, which previously found full-payment rates between 44% and 46%.

Roughly 26% received partial payments, and 24.5% received nothing at all despite having a legal order or agreement in place.² For parents receiving partial payments, the inconsistency makes budgeting nearly impossible. A custodial parent planning around $500 a month who actually gets $200 some months and nothing in others often ends up relying on credit cards or public assistance to cover the gap.

The bigger problem sits upstream of enforcement. Only 41% of the 13.9 million custodial parents in 2022 had either a court order or an informal agreement for financial support.² The share with formal legal agreements has fallen from 55.1% in 2003 to 37.3% in 2022. Without a legal order, parents cannot access federal enforcement tools, and millions of children receive no structured support at all.

Custodial-parent households also face a family poverty rate of 20.7%, roughly double the national rate.² An earlier federal analysis found that 61% of children receiving services through the Title IV-D program lived in poverty or near poverty, compared with 49% of children whose parents were not using IV-D services.³

Why Individual Balances Keep Growing

About 34 states charge interest on unpaid child support, and interest is a major reason individual balances balloon past the original amount owed. Rates range from 4% per year in states like Minnesota and New Mexico up to 12% in states like Kentucky and Washington. Some states compound the interest; others, like Arizona, use simple interest on the principal only.

A $10,000 arrears balance at 10% interest grows by $1,000 per year before a single payment is applied. In compounding states, the growth accelerates. Several states have created arrears compromise or debt reduction programs for exactly this reason: when parents see a debt they can never realistically pay off, they are less likely to pay anything at all.

How Collections Actually Happen

Wage withholding does most of the work. Employers withhold about 75% of all child support collected nationwide, routing money directly from the noncustodial parent’s paycheck before they see it. The automatic nature of the process is why most successful collections happen without the paying parent ever writing a check.

Federal tax refund offsets come next. Through the Treasury Offset Program, the Bureau of the Fiscal Service intercepts tax refunds from parents who owe past-due support and redirects the money to arrears.⁴ Unemployment benefits and certain other federal payments can be intercepted the same way. The program’s overall cost-effectiveness ratio was $4.24 collected for every $1 spent in FY 2024.¹

What Happens If a Parent Doesn’t Pay

Nonpayment triggers several escalating consequences, and they stack rather than replace each other.

Credit reporting. Federal law requires states to report delinquent child support to consumer credit agencies, where it damages credit scores and shows up to lenders, landlords, and employers who run credit checks.⁵
Passport denial. When arrears exceed $2,500, the State Department will refuse to issue or renew a passport and can revoke an existing one. Removal from the denial list typically requires paying the balance down or arranging payment with the state agency.⁶
License suspension. Most states can suspend driver’s, professional, and recreational licenses for child support delinquency. This tool is especially effective against self-employed parents whose income is not reached by wage withholding.
Civil contempt and jail. Courts can hold a noncustodial parent in contempt for nonpayment, but the Supreme Court held in Turner v. Rogers (2011) that incarceration requires a finding that the parent has the actual, present ability to pay and is choosing not to. States must screen cases before pursuing contempt.⁷

The ability-to-pay rule is a real protection. A parent who lost work or became disabled cannot be jailed just for being unable to afford the ordered amount. The catch is that parents who don’t show up in court or don’t request a modification can still be found in contempt by default.

Modifying an Order When Income Drops

Federal law requires every state to review and, if appropriate, adjust child support orders at least every three years when either parent asks. During these scheduled reviews, the requesting parent does not need to prove a change in circumstances; the state recalculates using current income and its guidelines.⁸

Outside the three-year cycle, a parent can still request review but must show a substantial change in circumstances, such as job loss or disability. States must notify parents of this right at least once every three years.⁸

Here is where many parents create a problem for themselves. An order stays in effect at its current amount until a court or agency formally changes it. Paying less than the ordered amount because income dropped, without filing for a modification, still creates arrears. Those arrears accrue interest in many states and generally cannot be reduced retroactively to before the modification was filed. If your financial situation changes, file right away rather than paying what you think you can afford.

Why Child Support Debt Doesn’t Go Away

Child support cannot be wiped out in bankruptcy. Federal bankruptcy law classifies it as a domestic support obligation and makes it non-dischargeable under both Chapter 7 and Chapter 13.⁹ Filing will not reduce, eliminate, or pause the obligation. Chapter 13 can let a parent fold past-due support into a three-to-five-year repayment plan, which helps spread out a large lump sum, but the full arrears balance has to be paid through the plan.

The debt also survives the death of the paying parent. In most states, arrears become a claim against the deceased parent’s estate, and the custodial parent can file in probate court to recover unpaid amounts from estate assets. Future support generally ends at death, but accumulated debt does not. Assets that pass directly to named beneficiaries, such as life insurance payouts, may bypass probate and sit out of reach in some states.

There is no federal statute of limitations on child support enforcement. Federal law requires states to keep enforcing orders as long as they remain in effect and to pursue arrears even after the child reaches adulthood. State time limits vary, from no limit at all to roughly 10 to 20 years after the obligation ends, depending on whether the state treats unpaid support as an ongoing obligation or as a civil judgment under its general judgment timeline. Arrears from the 1990s can still produce wage garnishment, tax offsets, and passport denial today. A custodial parent can forgive the private portion of a debt, but money owed to the state for reimbursed public assistance generally cannot be waived.
