Your refund may be reduced to pay a past due obligation such as child support, another federal agency debt, or state income tax. If this applies to you, the Financial Management Service, who issues IRS refunds, will send you a notice informing you of any offset they have made. The details of the debt are not provided to the IRS. Please do not call us to inquire about the details because we will not be able to answer your questions. Instead, direct any questions you have about the offset or debt to the agency identified on the notice.
