Yes, the state can take money from child support, but only in specific situations. The most common one is when the custodial parent’s family has received Temporary Assistance for Needy Families (TANF); federal law treats the collected support as reimbursement for those benefits. States also charge a small annual service fee once collections cross a threshold, and they can intercept federal tax refunds when a non-custodial parent owes arrears. How much actually reaches your family depends on whether you currently receive assistance, formerly received it, or never received it at all.
Why the State Keeps Some Support: The TANF Assignment
When a custodial parent applies for TANF, federal law requires them to assign their child support rights to the state as a condition of receiving benefits.1Administration for Children and Families. Guidance on Child Support Cooperation and Good Cause Provisions That means the parent legally transfers the right to collect and keep support payments while receiving assistance. The state then pursues the non-custodial parent through the Title IV-D enforcement program and uses what it collects to offset the cost of the benefits it paid.
The assignment is capped at the total amount of assistance the state provided, and it covers only support that accrues while the family receives benefits. Once the family stops receiving TANF, the state cannot require them to assign rights to future support.2GovInfo. 42 USC 608 – Prohibitions; Requirements Current monthly support at that point goes to the custodial parent. The state may still have a claim to past-due support that built up during the assistance period.
How Much of My Child Support Do I Actually Get?
Federal law sets a distribution hierarchy, and it works very differently for three groups of families.
Currently Receiving TANF
The state keeps most of the collected support to reimburse itself and the federal government for benefits paid. Any amount collected is split between the federal and state governments, with only the remainder going to the family.3Office of the Law Revision Counsel. 42 USC 657 – Distribution of Collected Support In practice, families on active TANF see little to none of the collected support unless their state has a pass-through policy.
Formerly Received TANF
Once a family leaves TANF, the rules shift heavily in the family’s favor. Current monthly support goes to the family first. Any collection beyond current obligation goes next to satisfy arrears owed to the family, meaning past-due support that built up during periods when the family was not receiving assistance. Only after both current support and family-owed arrears are paid does the remaining money go toward reimbursing the state for its TANF costs.3Office of the Law Revision Counsel. 42 USC 657 – Distribution of Collected Support
Never Received TANF
There is no assigned debt and no state reimbursement claim. All collected support goes directly to the family. The only deduction is the annual service fee described below.
State-Owed Arrears: Why the State Can Still Take Payments After You Leave TANF
When a non-custodial parent falls behind while the family is on TANF, the unpaid support doesn’t disappear. It becomes “assigned arrears” or “state-owed arrears,” owed to the government rather than the family. The state was paying benefits during that period, so it steps into the family’s shoes as creditor for the missed payments.
These arrears can persist for years. The state keeps collecting on that debt even after the family leaves TANF, and any payments applied to state-owed arrears go to the government. For families who spent extended time on assistance, the assigned balance can be substantial, especially in states that charge interest on unpaid support.
Pass-Through Payments for Families Still on TANF
Pass-through policies are the main exception to the rule that families on TANF don’t see their child support. Federal law allows states to pass through up to $100 per month for families with one child, or up to $200 for families with two or more children, without reducing the family’s TANF benefits.3Office of the Law Revision Counsel. 42 USC 657 – Distribution of Collected Support The passed-through amount is disregarded when TANF eligibility is calculated, so it functions as extra money for the family rather than a replacement for benefits.
About half of states have adopted some version of a pass-through. Some pass through the full federal maximum; others pass through smaller amounts like $50. Whether your family benefits depends entirely on which state you live in. Your local child support office can confirm whether a pass-through applies and what the current dollar amount is.
The $35 Annual Service Fee
Families who have never received TANF and use the state’s enforcement services are subject to a $35 annual fee. The fee only kicks in after the state has collected at least $550 in support for the family during the year.4Office of the Law Revision Counsel. 42 USC 654 – State Plan for Child and Spousal Support It covers administrative costs like locating non-custodial parents, establishing paternity, and enforcing court orders.
States can collect the fee in several ways: deducting it from a support payment (though not from the first $550 collected), billing the non-custodial parent directly, or absorbing it with state funds. The fee does not apply to families who received TANF, since those families already repay the state through the assignment. The current $35 amount and $550 threshold were set by the Bipartisan Budget Act of 2018, raising both figures from the earlier $25 fee and $500 threshold.5Congressional Research Service.

Federal Tax Refund Intercepts
When a non-custodial parent owes past-due child support, the state can refer the case to the U.S. Treasury Department to intercept that parent’s federal tax refund. For arrears assigned to the state during a TANF period, the statute sets no specific minimum dollar threshold. For arrears owed to a family that was never on public assistance, the past-due balance must be at least $500 before the state can request an offset.6Office of the Law Revision Counsel. 42 USC 664 – Collection of Past-Due Support From Federal Tax Refunds
Intercepted refund money follows the same distribution rules as any other collection. For former assistance families, current support and family-owed arrears are satisfied before the state keeps anything.
Protecting a Joint Refund
If the non-custodial parent filed jointly with a new spouse, the entire refund can be intercepted, including the new spouse’s share. The new spouse can reclaim their portion by filing IRS Form 8379 (Injured Spouse Allocation).7Internal Revenue Service. Instructions for Form 8379 The form splits the joint return as though each spouse had filed separately, and the IRS releases the injured spouse’s portion.
Form 8379 can be filed with the original return or after the offset has occurred. Processing takes roughly 11 weeks electronically or 14 weeks on paper. Filed separately after processing, it takes about 8 weeks. In community property states, special rules apply and may limit recovery to 50% of the joint overpayment.7Internal Revenue Service. Instructions for Form 8379
Other Programs That Trigger a Support Assignment
TANF is not the only program that triggers an assignment. When a child enters foster care under the federal Title IV-E program, the state must secure an assignment of child support rights on behalf of that child.8Child Welfare Policy Manual. Title IV-E, General Title IV-E Requirements, Child Support The foster care agency evaluates each case individually and considers whether pursuing support from the parent would interfere with reunification. A child’s Title IV-E eligibility is not affected if a parent refuses to cooperate with the assignment.
Medicaid also requires applicants to assign to the state any rights they have to medical support or third-party payments for medical care.9Social Security Administration. Assignment of Rights for Medicaid Eligibility If a child support order includes a medical support component and the child receives Medicaid, the state can retain that portion to reimburse itself for healthcare costs. Refusing to assign these rights generally results in denial of Medicaid eligibility.
What to Do If You Think the State Is Taking Too Much
Contact your local child support agency and request a detailed payment history showing how each payment was distributed between current support, family-owed arrears, and state-owed arrears. Every state is required to maintain a State Disbursement Unit that tracks these distributions.
If you believe the state has been fully reimbursed for the TANF benefits you received and should no longer be retaining payments, ask the agency to review the assigned arrears balance. Errors happen, particularly in older cases or ones that have transferred between states. If your state offers a pass-through policy and you currently receive TANF, confirm the amount is being applied to your case. It is not always applied automatically.
