The federal government can take your tax refund for unpaid child support once you owe as little as $150 or $500, depending on whether the child ever received public assistance. If the child received Temporary Assistance for Needy Families (TANF) at any point, the threshold is $150. If the child never received TANF, the threshold is $500. Once your arrears reach the applicable number, your state child support agency can refer your case to the federal Treasury Offset Program, which will intercept your refund the next time you file.
The Two Thresholds Explained
Federal regulation sets two dollar amounts, and which one applies to you turns on the child’s history with public benefits.1eCFR. 45 CFR 303.72
- $150 if the child ever received TANF. The lower figure exists because the state is recovering money it already paid out on the child’s behalf, and the past-due support in that situation is assigned to the state.
- $500 if the child never received TANF and the state agency is enforcing the order on behalf of the custodial parent.
States can combine what you owe across multiple cases to reach either threshold, but the two categories cannot be mixed together. If you owe $100 in TANF-assigned arrears and $400 in non-TANF arrears, neither category meets its own minimum on its own, so neither qualifies for offset. Each bucket has to clear its own floor independently.
Meeting the Threshold Is the Only Trigger
There is no separate requirement that you’ve missed a certain number of payments or been delinquent for any specific stretch of time. If your past-due balance clears $150 or $500, your refund is eligible for interception. Making consistent partial payments on the arrears does not take you out of the program. As long as the total owed sits above the threshold when the state certifies the debt, the offset can happen.
How the Interception Works
Your local child support enforcement agency flags your account once your arrears meet the federal threshold, then certifies the debt by sending your name, Social Security number, and the amount owed to the federal Office of Child Support Services. From there it moves to the Department of the Treasury’s Bureau of the Fiscal Service, which runs the Treasury Offset Program and matches your record against outgoing federal payments.2Administration for Children & Families. How Does a Federal Tax Refund Offset Work?3Bureau of the Fiscal Service. Treasury Offset Program
When you file your federal return and a refund is generated, the system reduces the refund by what you owe, or takes the entire refund if it’s smaller than the debt, and routes the money to the state agency. The state typically receives the funds within two to three weeks. For an individual return, federal law requires the state to send the money to the custodial parent within 30 calendar days of receiving it, barring something like a pending appeal.
A small administrative fee is deducted from the intercepted amount before anyone sees the money. Federal regulations cap this fee at $25 per case, and it is only charged when an actual offset occurs.4eCFR. 31 CFR Part 285 Subpart A
If you owe other debts too, child support gets paid first. Federal law puts past-due child support ahead of federal agency debts, state income tax debts, and unemployment overpayments when a refund is split across multiple claims.5Office of the Law Revision Counsel. 26 USC 6402
The Pre-Offset Notice and Your Right to Challenge
Before any money is taken, the state child support agency must send you a written Pre-Offset Notice. The notice tells you the amount of past-due support being reported, how to contest it, and how a spouse filing jointly can protect their share.6eCFR. 31 CFR 285.3 It also warns that your debt may trigger other federal enforcement actions, such as passport denial.
You can request an administrative review with the state agency after receiving the notice. The deadline varies by state but is typically around 30 days from the date on the notice. The grounds for a successful challenge are narrow:
- You are not the person who owes the support.
- Your support order was vacated, terminated, or never entered.
- The amount is wrong because payments weren’t credited, the calculation is off, or an order modification wasn’t reflected.
Disagreeing with the original order or thinking the amount is unfair is not a basis for stopping the offset. The review is about whether the reported debt is accurate, not whether the underlying order should exist. If only part of the amount is disputed, the undisputed portion remains eligible for interception.
If You File Jointly With a Spouse
When someone who owes child support files a joint return with a spouse who doesn’t owe the debt, the entire joint refund gets intercepted. The spouse who doesn’t owe is called the “injured spouse” and can file IRS Form 8379, Injured Spouse Allocation, to recover their share.7Internal Revenue Service. Injured Spouse Relief The form can be submitted electronically with the joint return, on paper with the return, or by itself after the refund has already been seized.8Internal Revenue Service. Instructions for Form 8379
The IRS recalculates the return as if each spouse had filed separately, based on each person’s income, withholding, and credits, and refunds the injured spouse’s portion. Processing takes roughly 11 weeks if the form is filed electronically with the return, 14 weeks if filed on paper with the return, and about 8 weeks if filed separately after the offset.9Internal Revenue Service. Injured Spouse Community property states follow their own allocation rules, so the split can look different there.
While that process plays out, the state child support agency can hold the intercepted joint-return funds for up to six months before releasing them to the custodial parent, so the IRS has time to issue an allocation decision.
Other Things That Can Happen at Higher Balances
Once your arrears exceed $2,500, the state can certify your debt to the U.S. Department of State, which will refuse to issue or renew your passport and can revoke an existing one.10Office of the Law Revision Counsel. 42 USC 652 The Treasury Offset Program also reaches beyond tax refunds to other federal payments, including federal salary, retirement benefits, and Social Security retirement and disability (though Supplemental Security Income is exempt).11Social Security Administration. Can My Social Security Benefits Be Garnished or Levied?
Most states run their own tax refund interception programs for child support arrears, often with lower thresholds than the federal minimums. If you owe back support, both your federal and state refunds may be at risk in the same tax year.
Bankruptcy will not stop any of this. The Bankruptcy Code specifically carves tax refund interception for child support out of the automatic stay, and child support debt itself cannot be discharged.12Office of the Law Revision Counsel. 11 USC 362 Filing Chapter 7 or Chapter 13 changes nothing about the government’s ability to seize your refund for arrears.
