The Treasury Department can take a federal tax refund to cover past-due child support, federal agency debts, state income tax or certain state unemployment compensation debts, the IRS says. The Bureau of the Fiscal Service does the taking through the Treasury Offset Program, and the refund that arrives can be smaller than the return said, or not arrive at all.
The IRS lists four kinds of debt that can reduce a refund: past-due child support, federal agency non-tax debts, state income tax obligations and certain state unemployment compensation debt. The Fiscal Service, which the IRS says “is authorized by Congress to conduct the Treasury Offset Program,” matches the debt to the payment. The IRS page was last updated June 1, 2026.
The question for anyone who owes one of those debts is whether a refund is already spoken for. The Bureau of the Fiscal Service mails a notice when an offset happens, and the IRS does not receive the details. A person who expects a refund and owes child support, a state tax bill or a federal agency debt should plan for the possibility that the deposit will fall short.

How does the Treasury match a debt to a refund?
The Fiscal Service describes the Treasury Offset Program as the collector of past-due debts that people and businesses owe to state and federal agencies, with child support as its example. The program matches people who owe delinquent debts with money that federal agencies are paying, and a tax refund is the example it gives. When there is a match, the money is withheld to pay the debt “to the extent allowed by law.”
The scale is large. The Fiscal Service says the program recovered more than $3.8 billion in federal and state delinquent debts in fiscal year 2024, across the debts the program handles for state and federal agencies.
What does the offset notice show?
The notice from the Bureau of the Fiscal Service “will show the original refund amount, your offset amount, and the agency receiving the payment,” the IRS says. Because the IRS does not get the offset details, a person who did not receive the notice should contact the Fiscal Service at 800-304-3107, or 800-877-8339 for TTY/TDD users. The IRS lists the hours as Monday to Friday, 7:30 a.m. to 5 p.m. CST.
The IRS says to contact it only if the refund amount on the notice differs from the amount on the tax return. For recurring payments such as benefits or salary, the Fiscal Service says it may send a warning letter before an offset, according to its page for people with offset debts.
Who answers for the debt itself?
The Treasury Offset Program staff cannot answer debt questions, resolve disputes or negotiate payment arrangements, the Fiscal Service says. Anyone who disagrees with a reduction has to contact the agency servicing the debt, and the same office can discuss a payment arrangement based on ability to pay. The IRS says a dispute should follow the instructions in the notice.
People can also call the program’s automated line at 1-800-304-3107 to find out whether they have a debt referred for offset. That call is the quickest way to learn whether child support, a state tax bill or a federal agency balance has been referred.
What if the debt was paid off, or never existed?
The Fiscal Service’s frequently asked questions, updated March 6, 2026, say a person whose payment was reduced for a debt they do not owe should contact the agency named in the notice. If the debt was paid in full or does not exist, the federal agency that authorized the collection must return any amount that should not have been taken, the page says. Anyone unsure which agency is involved can call the program’s automated line at 800-304-3107.
The same FAQ says the debtor is notified in advance of any offset action, and the offset notice follows once money is taken. For child support, a state can use the program to offset certain federal payments, and people are told to contact their state or local child-support office to learn whether that applies. The collected money goes to the Department of Health and Human Services, which sends it to the states, and the HHS Office of Child Support Enforcement answers questions at 202-401-9373.
What if a spouse’s debt took a joint refund?
When a joint return produces a refund that pays only one spouse’s debt, the other spouse may be entitled to get back a portion, the IRS says. The claim is made with IRS Form 8379, Injured Spouse Allocation, according to the Fiscal Service. For help with the form, it points people to a local IRS office or 800-829-1040.
The Fiscal Service says to use that form when a joint refund was offset for a spouse’s debt, and the IRS says a spouse who is not responsible for the debt may be entitled to get back their portion. A joint filer who sees a short deposit should look at the offset notice first to see whose debt it names. The FAQ adds that anyone who has already filed Form 8379 and still sees the refund offset can call 800-829-1040.
Refund came back smaller than the return said?
An offset notice lists the original refund, the amount taken and the agency that received it, and it is easy to set aside with the rest of the mail. A smaller deposit with no explanation can leave a household short on a bill it was counting on.
The IRS Refund Recovery Kit is a 20-page guide that includes a notice decoder and a refund status tracker spreadsheet. Part 6, “A Smaller Refund, or None at All,” is written for the situation where the amount that arrived does not match the return.
